Beschreibung: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉Infrared spectroscopy in the visible to near‐infrared (vis–NIR) and mid‐infrared (MIR) regions is a well‐established approach for the prediction of soil properties. Different data fusion and training approaches exist, and the optimal procedures are yet undefined and may depend on the heterogeneity present in the set and on the considered scale. The objectives were to test the usefulness of partial least squares regressions (PLSRs) for soil organic carbon (SOC), total carbon (C〈sub〉t〈/sub〉), total nitrogen (N〈sub〉t〈/sub〉) and pH using vis–NIR and MIR spectroscopy for an independent validation after standard calibration (use of a general PLSR model) or using memory‐based learning (MBL) with and without spiking for a national spectral database. Data fusion approaches were simple concatenation of spectra, outer product analysis (OPA) and model averaging. In total, 481 soils from an Austrian forest soil archive were measured in the vis–NIR and MIR regions, and regressions were calculated. Fivefold calibration‐validation approaches were carried out with a region‐related split of spectra to implement independent validations with n ranging from 47 to 99 soils in different folds. MIR predictions were generally superior over vis–NIR predictions. For all properties, optimal predictions were obtained with data fusion, with OPA and spectra concatenation outperforming model averaging. The greatest robustness of performance was found for OPA and MBL with spiking with 〈italic toggle="no"〉R〈/italic〉〈sup〉2〈/sup〉 ≥ 0.77 (N), 0.85 (SOC), 0.86 (pH) and 0.88 (C〈sub〉t〈/sub〉) in the validations of all folds. Overall, the results indicate that the combination of OPA for vis–NIR and MIR spectra with MBL and spiking has a high potential to accurately estimate properties when using large‐scale soil spectral libraries as reference data. However, the reduction of cost‐effectiveness using two spectrometers needs to be weighed against the potential increase in accuracy compared to a single MIR spectroscopy approach.〈/p〉

Beschreibung: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉In recent years, many two‐dimensional (2D) hydrodynamic models have been extended to include the direct rainfall method (DRM). This allows their application as a hydrological‐hydrodynamic model for the determination of floodplains in one model system. In previous studies on DRM, the role of catchment hydrological processes (CaHyPro) and its interaction with the calibration process was not investigated in detail. In the present, case‐oriented study, the influence of the spatiotemporal distribution of the processes precipitation and runoff formation in combination with the 2D model HEC‐RAS is investigated. In a further step, a conceptual approach for event‐based interflow is integrated. The study is performed on the basis of a single storm event in a small rural catchment (low mountain range, 38 km〈sup〉2〈/sup〉) in Hesse (Germany). The model results are evaluated against six quality criteria and compared to a simplified baseline model. Finally, the calibrated improved model is contrasted with a calibrated baseline model. The results show the enhancement of the model results due to the integration of the CaHyPro and highlight its interplay with the calibrated model parameters.〈/p〉

Beschreibung: Spatiotemporal characterisation of the soil redox status within the capillary fringe (CF) is a challenging task. Air‐filled porosities (ε), oxygen concentration (O〈sub〉2〈/sub〉) and soil redox potential (EH) are interrelated soil variables within active biogeochemical domains such as the CF. We investigated the impact of water table (WT) rise and drainage in an undisturbed topsoil and subsoil sample taken from a Calcaric Gleysol for a period of 46 days. We merged 1D (EH and matric potential) and 2D (O〈sub〉2〈/sub〉) systems to monitor at high spatiotemporal resolution redox dynamics within self‐constructed redoxtron housings and complemented the data set by a 3D pore network characterization using X‐ray microtomography (X‐ray μCT). Depletion of O〈sub〉2〈/sub〉 was faster in the organic matter‐ and clay‐rich aggregated topsoil and the CF extended 〉10 cm above the artificial WT. The homogeneous and less‐aggregated subsoil extended only 4 cm above the WT as indicated by ε–O〈sub〉2〈/sub〉–EH data during saturation. After drainage, 2D O〈sub〉2〈/sub〉 imaging revealed a fast aeration towards the lower depths of the topsoil, which agrees with the connected ε derived by X‐ray μCT (ε〈sub〉CT_conn〈/sub〉) of 14.9% of the total porosity. However, small‐scaled anoxic domains with O〈sub〉2〈/sub〉 saturation 〈5% were apparent even after lowering the WT (down to 0.25 cm〈sup〉2〈/sup〉 in size) for 23 days. These domains remained a nucleus for reducing soil conditions (E〈sub〉H〈/sub〉 〈 −100 mV), which made it challenging to characterise the soil redox status in the CF. In contrast, the subsoil aeration reached O〈sub〉2〈/sub〉 saturation after 8 days for the complete soil volume. Values of ε〈sub〉CT_conn〈/sub〉 around zero in the subsoil highlighted that soil aeration was independent of this parameter suggesting that other variables such as microbial activity must be considered when predicting the soil redox status from ε alone. The use of redoxtrons in combination with localised redox‐measurements and image based pore space analysis resulted in a better 2D/3D characterisation of the pore system and related O〈sub〉2〈/sub〉 transport properties. This allowed us to analyse the distribution and activity of microbiological niches highly associated with the spatiotemporal variable redox dynamics in soil environments. Highlights: The time needed to turn from reducing to oxidising (period where all platinum electrodes feature E〈sub〉H〈/sub〉 〉 300 mV) condition differ for two samples with contrasting soil structure. The subsoil with presumably low O〈sub〉2〈/sub〉 consumption rates aerated considerably faster than the topsoil and exclusively by O〈sub〉2〈/sub〉 diffusion through medium‐ and fine‐sized pores. To derive the soil redox status based upon the triplet ε–O〈sub〉2〈/sub〉–E〈sub〉H〈/sub〉 is challenging at present in heterogeneous soil domains and larger soil volumes than 250 cm〈sup〉3〈/sup〉. Undisturbed soil sampling along with 2D/3D redox measurement systems (e.g., redoxtrons) improve our understanding of redox dynamics within the capillary fringe.

As treatment changes have occurred due to agricultural advancements, so too have analytical soil methods. This may lead to method bias over time, which could affect the robust interpretation of data and conclusions drawn. This study aims to quantify differences in SOC due to changes in dry combustion methods over time, using soil samples of a LTE established in 1963 that focuses on mineral and organic fertilizer management in the temperate zone of Northeast Germany. For this purpose, 1059 soil samples, collected between 1976 and 2008, have been analysed twice, once with their historical laboratory method right after sampling, and a second time in 2016 when all samples were analysed using the same elementary analyser. In 9 of 11 soil sampling campaigns, a paired 〈italic toggle="no"〉t〈/italic〉‐test provided evidence for significant differences in the historical SOC values when compared with the re‐analysed concentrations of the same LTE sample. In the sampling years 1988 and 2004, the historical analysis obtained about 0.9 g kg〈sup〉−1〈/sup〉 lower SOC compared with the re‐analysed one. For 1990 and 1998, this difference was about 0.4 g kg〈sup〉−1〈/sup〉. Correction factors, an approach often used to correct for different analytical techniques, could only be applied for 5 of 11 sampling campaigns to account for constant and proportional systematic method error. For this particular LTE, the interpretation of SOC changes due to agronomic management (here fertilization) deviates depending on the analytical method used, which may weaken the explanatory power of the historical data. We demonstrate that analytical method changes over time present one of many challenges in the interpretation of time series data of SOC dynamics. Therefore, LTE site managers need to ensure providing all necessary protocols and data in order to retrace method changes and if necessary recalculate SOC.〈/p〉 〈/sec〉〈sec xmlns:mml="http://www.w3.org/1998/Math/MathML" id="ejss13362-sec-0003" xml:lang="en"〉 〈title〉Highlights〈/title〉 〈p xml:lang="en"〉〈list list-type="bullet" id="ejss13362-list-0001"〉 〈list-item id="ejss13362-li-0001"〉〈p〉A total of 1059 LTE soil samples taken between 1976 and 2008 were re‐analysed for SOC in 2016〈/p〉〈/list-item〉 〈list-item id="ejss13362-li-0002"〉〈p〉Several methodological changes for SOC determination led to significant different SOC concentration in the same sample〈/p〉〈/list-item〉 〈list-item id="ejss13362-li-0003"〉〈p〉Interpretation and time series of LTE soil data suffer from consideration of analytical method changes and poor documentation of the same〈/p〉〈/list-item〉 〈list-item id="ejss13362-li-0004"〉〈p〉Soil archive establishment, thorough method protocols and diligent proficiency testing after soil method changes ameliorate the dilemma〈/p〉〈/list-item〉 〈/list〉〈/p〉 〈/sec〉

Many methods and data sets have been refined considerably to cover more details of spatial, temporal, or process information. We compile case studies indicating that refined methods and data have a considerable effect on the overall assessment of flood risk. But are these improvements worth the effort? The adequate level of detail is typically unknown and prioritization of improvements in a specific component is hampered by the lack of an overarching view on flood risk. Consequently, creating the dilemma of potentially being too greedy or too wasteful with the resources available for a risk assessment. A “sweet spot” between those two would use methods and data sets that cover all relevant known processes without using resources inefficiently. We provide three key questions as a qualitative guidance toward this “sweet spot.” For quantitative decision support, more overarching case studies in various contexts are needed to reveal the sensitivity of the overall flood risk to individual components. This could also support the anticipation of unforeseen events like the flood event in Germany and Belgium in 2021 and increase the reliability of flood risk assessments.〈/p〉

Beschreibung: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉The increasing demand for biomass for food, animal feed, fibre and bioenergy requires optimization of soil productivity, while at the same time, protecting other soil functions such as nutrient cycling and buffering, carbon storage, habitat for biological activity and water filter and storage. Therefore, one of the main challenges for sustainable agriculture is to produce high yields while maintaining all the other soil functions. Mechanistic simulation models are an essential tool to fully understand and predict the complex interactions between physical, biological and chemical processes of soils that generate those functions. We developed a soil model to simulate the impact of various agricultural management options and climate change on soil functions by integrating the relevant processes mechanistically and in a systemic way. As a special feature, we include the dynamics of soil structure induced by tillage and biological activity, which is especially relevant in arable soils. The model operates on a 1D soil profile consisting of a number of discrete layers with dynamic thickness. We demonstrate the model performance by simulating crop growth, root growth, nutrient and water uptake, nitrogen cycling, soil organic matter turnover, microbial activity, water distribution and soil structure dynamics in a long‐term field experiment including different crops and different types and levels of fertilization. The model is able to capture essential features that are measured regularly including crop yield, soil organic carbon, and soil nitrogen. In this way, the plausibility of the implemented processes and their interactions is confirmed. Furthermore, we present the results of explorative simulations comparing scenarios with and without tillage events to analyse the effect of soil structure on soil functions. Since the model is process‐based, we are confident that the model can also be used to predict quantities that have not been measured or to estimate the effect of management measures and climate states not yet been observed. The model thus has the potential to predict the site‐specific impact of management decisions on soil functions, which is of great importance for the development of a sustainable agriculture that is currently also on the agenda of the ‘Green Deal’ at the European level.〈/p〉

Beschreibung: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉Temperature and soil moisture are known to control pesticide mineralization. Half‐life times (DT〈sub〉50〈/sub〉) derived from pesticide mineralization curves generally indicate longer residence times at low soil temperature and moisture but do not consider potential changes in the microbial allocation of pesticide‐derived carbon (C). We aimed to determine carbon use efficiency (CUE, formation of new biomass relative to total C uptake) to better understand microbial utilization of pesticide‐derived C under different environmental conditions and to support the conventional description of degradation dynamics based on mineralization. We performed a microcosm experiment at two MCPA (2‐methyl‐4‐chlorophenoxyacetic acid) concentrations (1 and 20 mg kg〈sup〉−1〈/sup〉) and defined 20°C/pF 1.8 as optimal and 10°C/pF 3.5 as limiting environmental conditions. After 4 weeks, 70% of the initially applied MCPA was mineralized under optimal conditions but MCPA mineralization reached less than 25% under limiting conditions. However, under limiting conditions, an increase in CUE was observed, indicating a shift towards anabolic utilization of MCPA‐derived C. In this case, increased C assimilation implied C storage or the formation of precursor compounds to support resistance mechanisms, rather than actual growth since we did not find an increase in the 〈italic toggle="no"〉tfdA〈/italic〉 gene relevant to MCPA degradation. We were able to confirm the assumption that under limiting conditions, C assimilation increases relative to mineralization and that C redistribution, may serve as an explanation for the difference between mineralization and MCPA dissipation‐derived degradation dynamics. In addition, by introducing CUE to the temperature‐ and moisture‐dependent degradation of pesticides, we can capture the underlying microbial constraints and adaptive mechanisms to changing environmental conditions.〈/p〉

Beschreibung: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉Gas transport in soils is usually assumed to be purely diffusive, although several studies have shown that non‐diffusive processes can significantly enhance soil gas transport. These processes include barometric air pressure changes, wind‐induced pressure pumping and static air pressure fields generated by wind interacting with obstacles. The associated pressure gradients in the soil can cause advective gas fluxes that are much larger than diffusive fluxes. However, the contributions of the respective transport processes are difficult to separate. We developed a large chamber system to simulate pressure fields and investigate their influence on soil gas transport. The chamber consists of four subspaces in which pressure is regulated by fans that blow air in or out of the chamber. With this setup, we conducted experiments with oscillating and static pressure fields. CO〈sub〉2〈/sub〉 concentrations were measured along two soil profiles beneath the chamber. We found a significant relationship between static lateral pressure gradients and the change in the CO〈sub〉2〈/sub〉 profiles (R〈sup〉2〈/sup〉 = 0.53; 〈italic toggle="no"〉p〈/italic〉‐value 〈2e‐16). Even small pressure gradients between −1 and 1 Pa relative to ambient pressure resulted in an increase or decrease in CO〈sub〉2〈/sub〉 concentrations of 8% on average in the upper soil, indicating advective flow of air in the pore space. Positive pressure gradients resulted in decreasing, negative pressure gradients in increasing CO〈sub〉2〈/sub〉 concentrations. The concentration changes were probably caused by an advective flow field in the soil beneath the chamber generated by the pressure gradients. No effect of oscillating pressure fields was observed in this study. The results indicate that static lateral pressure gradients have a substantial impact on soil gas transport and therefore are an important driver of gas exchange between soil and atmosphere. Lateral pressure gradients in a comparable range can be induced under windy conditions when wind interacts with terrain features. They can also be caused by chambers used for flux measurements at high wind speed or by fans used for head‐space mixing within the chambers, which yields biased flux estimates.〈/p〉

Beschreibung: Charcoal‐rich Technosols on century‐old relict charcoal hearths (RCHs) are the subject of ongoing research regarding potential legacy effects that result from historic charcoal production and subsequent charcoal amendments on forest soil properties and forest ecosystems today. RCHs consist mostly of Auh horizons that are substantially enriched in soil organic carbon (SOC), of which the largest part seems to be of pyrogenic origin (PyC). However, the reported range of SOC and PyC contents in RCH soil also suggests that they are enriched in nonpyrogenic SOC. RCH soils are discussed as potential benchmarks for the long‐term influence of biochar amendment and the post‐wildfire influences on soil properties. In this study, we utilised a large soil sample dataset (n = 1245) from 52 RCH sites in north‐western Connecticut, USA, to quantify SOC contents by total element analysis. The contents of condensed highly aromatic carbon as a proxy for black carbon (BC) were predicted by using a modified benzene polycarboxylated acid (BPCA) marker method in combination with diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy‐based partial least square regression (r2 = 0.89). A high vertical spatial sampling resolution allowed the identification of soil organic matter (SOM) enrichment and translocation processes. The results show an average 75% and 1862% increase in TOC and BPCA‐derived carbon, respectively, for technogenic Auh horizons compared to reference soils. In addition to an increase in aromatic properties, increased carboxylic properties of the RCH SOC suggest self‐humification effects of degrading charcoal and thereby the continuing formation of leachable aromatic carbon compounds, which could have effects on pedogenic processes in buried soils. Indeed, we show BPCA‐derived carbon concentrations in intermediate technogenic Cu horizons and buried top/subsoils that suggest vertical translocation of highly aromatic carbon originating in RCH Auh horizons. Topmost Auh horizons showed a gradual decrease in total organic carbon (TOC) contents with increasing depth, suggesting accumulation of recent, non‐pyrogenic SOM. Lower aliphatic absorptions in RCH soil spectra suggest different SOM turnover dynamics compared to reference soils. Furthermore, studied RCH soils featured additional TOC enrichment, which cannot be fully explained now. Highlights BC to TOC ratio and high resolution vertical SOC distribution in 52 RCH sites were studied. RCH soils non‐BC pool was potentially different to reference soils. RCH soils feature TOC accumulation in the topmost horizon. There is BC translocation into buried soils on RCH sites.

Beschreibung: Little research attention has been given to validating clusters obtained from the groundwater geochemistry of the waterworks' capture zone with a prevailing lake‐groundwater exchange. To address this knowledge gap, we proposed a new scheme whereby Gaussian finite mixture modeling (GFMM) and Spike‐and‐Slab Bayesian (SSB) algorithms were utilized to cluster the groundwater geochemistry while quantifying the probability of the resulting cluster membership against each other. We applied GFMM and SSB to 13 geochemical parameters collected during different sampling periods at 13 observation points across the Barnim Highlands plateau located in the northeast of Berlin, Germany; this included 10 observation wells, two lakes, and a gallery of drinking production wells. The cluster analysis of GFMM yielded nine clusters, either with a probability ≥0.8, while the SSB produced three hierarchical clusters with a probability of cluster membership varying from 〈0.2 to 〉0.8. The findings demonstrated that the clustering results of GFMM were in good agreement with the classification as per the principal component analysis and Piper diagram. By superimposing the parameter clustering onto the observation clustering, we could identify discrepancies that exist among the parameters of a certain cluster. This enables the identification of different factors that may control the geochemistry of a certain cluster, although parameters of that cluster share a strong similarity. The GFMM results have shown that from 2002, there has been active groundwater inflow from the lakes towards the capture zone. This means that it is necessary to adopt appropriate measures to reverse the inflow towards the lakes.

Beschreibung: Article impact statement: The probability of cluster membership quantified using an algorithm should be validated against another probabilistic‐based classifier.

Beschreibung: Copper (Cu) is an essential element for plants and microorganisms and at larger concentrations a toxic pollutant. A number of factors controlling Cu dynamics have been reported, but information on quantitative relationships is scarce. We aimed to (i) quantitatively describe and predict soil Cu concentrations (CuAR) in aqua regia considering site‐specific effects and effects of pH, soil organic carbon (SOC) and cation exchange capacity (CEC), and (ii) study the suitability of mixed‐effects modelling and rule‐based models for the analysis of long‐term soil monitoring data. Thirteen uncontaminated long‐term monitoring soil profiles in southern Germany were analysed. Since there was no measurable trend of increasing CuAR concentrations with time in the respective depth ranges of the sites, data from different sampling dates were combined and horizon‐specific regression analyses including model simplifications were carried out for 10 horizons. Fixed‐ and mixed‐effects models with the site as a random effect were useful for the different horizons and significant contributions (either of main effects or interactions) of SOC, CEC and pH were present for 9, 8 and 7 horizons, respectively. Horizon‐specific rule‐based cubist models described the CuAR data similarly well. Validations of cubist models and mixed‐effects models for the CuAR concentrations in A horizons were successful for the given population after random splitting into calibration and validation samples, but not after independent validations with random splitting according to sites. Overall, site, CEC, SOC and pH provide important information for a description of CuAR concentrations using the different regression approaches. Highlights: Information on quantitative relationships for factors controlling Cu dynamics is scarce. Site, CEC, SOC and pH provide important information for a description of Cu concentrations. Validations of cubist models and mixed‐effects models for A horizons were successful for a closed population of sites.

Beschreibung: Soil aeration is a critical factor for oxygen‐limited subsoil processes, as transport by diffusion and advection is restricted by the long distance to the free atmosphere. Oxygen transport into the soil matrix is highly dependent on its connectivity to larger pore channels like earthworm and root colonised biopores. Here we hypothesize that the soil matrix around biopores represents different connectivity depending on biopore genesis and actual coloniser. We analysed the soil pore system of undisturbed soil core samples around biopores generated or colonised by roots and earthworms and compared them with the pore system of soil, not in the immediacy of a biopore. Oxygen partial pressure profiles and gas relative diffusion was measured in the rhizosphere and drilosphere from the biopore wall into the bulk soil with microelectrodes. The measurements were linked with structural features such as porosity and connectivity obtained from X‐ray tomography and image analysis. Aeration was enhanced in the soil matrix surrounding biopores in comparison to the bulk soil, shown by higher oxygen concentrations and higher relative diffusion coefficients. Biopores colonised by roots presented more connected lateral pores than earthworm colonised ones, which resulted in enhanced aeration of the rhizosphere compared to the drilosphere. This has influenced biotic processes (microbial turnover/mineralization or root respiration) at biopore interfaces and highlights the importance of microstructural features for soil processes and their dependency on the biopore's coloniser.

Beschreibung: Application of farmyard manure (FYM) is common practice to improve physical and chemical properties of arable soil and crop yields. However, studies on effects of FYM application mainly focussed on topsoils, whereas subsoils have rarely been addressed so far. We, therefore, investigated the effects of 36‐year FYM application with different rates of annual organic carbon (OC) addition (0, 469, 938 and 1875 g C m−2 a−1) on OC contents of a Chernozem in 0–30 cm (topsoil) and 35–45 cm (subsoil) depth. We also investigated its effects on soil structure and hydraulic properties in subsoil. X‐ray computed tomography was used to analyse the response of the subsoil macropore system (≥19 μm) and the distribution of particulate organic matter (POM) to different FYM applications, which were related to contents in total OC (TOC) and water‐extractable OC (WEOC). We show that FYM‐C application of 469 g C m−2 a−1 caused increases in TOC and WEOC contents only in the topsoil, whereas rates of ≥938 g C m−2 a−1 were necessary for TOC enrichment also in the subsoil. At this depth, the subdivision of TOC into different OC sources shows that most of the increase was due to fresh POM, likely by the stimulation of root growth and bioturbation. The increase in subsoil TOC went along with increases in macroporosity and macropore connectivity. We neither observed increases in plant‐available water capacity nor in unsaturated hydraulic conductivity. In conclusion, only very high application of FYM over long periods can increase OC content of subsoil at our study site, but this increase is largely based on fresh, easily degradable POM and likely accompanied by high C losses when considering the discrepancy between OC addition rate by FYM and TOC response in soil. Highlights A new image processing procedure to distinguish fresh and decomposed POM. The increase of subsoil C stock based to a large extend on fresh, labile POM. Potential of arable subsoils for long‐term C storage by large FYM application rates is limited. The increase in TOC has no effect on hydraulic properties of the subsoil.

Beschreibung: Erosion is a severe threat to the sustainable use of agricultural soils. However, the structural resistance of soil against the disruptive forces steppe soils experience under field conditions has not been investigated. Therefore, 132 topsoils under grass‐ and cropland covering a large range of physico‐chemical soil properties (sand: 2–76%, silt: 18–80%, clay: 6–30%, organic carbon: 7.3–64.2 g kg−1, inorganic carbon: 0.0–8.5 g kg−1, pH: 4.8–9.5, electrical conductivity: 32–946 μS cm−1) from northern Kazakhstan were assessed for their potential erodibility using several tests. An adjusted drop‐shatter method (low energy input of 60 Joule on a 250‐cm3 soil block) was used to estimate the stability of dry soil against weak mechanical forces, such as saltating particles striking the surface causing wind erosion. Three wetting treatments with various conditions and energies (fast wetting, slow wetting, and wet shaking) were applied to simulate different disruptive effects of water. Results indicate that aggregate stability was higher for grassland than cropland soils and declined with decreasing soil organic carbon content. The results of the drop‐shatter test suggested that 29% of the soils under cropland were at risk of wind erosion, but only 6% were at high risk (i.e. erodible fraction 〉60%). In contrast, the fast wetting treatment revealed that 54% of the samples were prone to become “very unstable” and 44% “unstable” during heavy rain or snowmelt events. Even under conditions comparable to light rain events or raindrop impact, 53–59% of the samples were “unstable.” Overall, cropland soils under semi‐arid conditions seem much more susceptible to water than wind erosion. Considering future projections of increasing precipitation in Kazakhstan, we conclude that the risk of water erosion is potentially underestimated and needs to be taken into account when developing sustainable land use strategies. Highlights Organic matter is the important binding agent enhancing aggregation in steppe topsoils. Tillage always declines aggregate stability even without soil organic carbon changes. All croplands soil are prone to wind or water erosion independent of their soil properties. Despite the semi‐arid conditions, erosion risk by water seems higher than by wind.

Beschreibung: Stable hydrogen isotope ratios (δ2H values) in structural hydroxyl groups of pedogenic clay minerals are inherited from the surrounding water at the time of their formation. Only non‐exchangeable H preserves the environmental forensic and paleoclimate information (δ2Hn value). To measure δ2Hn values in structural H of clay minerals and soil clay fractions, we adapted a steam equilibration method by accounting for high hygroscopicity. Our δ2Hn values for USGS57 biotite (−95.3 ± SD 0.9‰) and USGS58 muscovite (30.7 ± 1.4‰) differed slightly but significantly from the reported δ2H values (−91.5 ± 2.4‰ and −28.4 ± 1.6‰), because the minerals contained 1.1%–4.4% of exchangeable H. The low SD of replicate measurements (n = 3) confirmed a high precision. The clay separation method including destruction of Fe oxides, carbonates and soil organic matter, and dispersion did not significantly change the δ2Hn values of five different clay minerals. However, we were unable to remove all organic matter from the soil clay fractions resulting in an estimated bias of 1‰ in two samples and 15‰ in the carbon‐richest sample. Our results demonstrate that δ2Hn values of structural H of clay minerals and soil clay fractions can be reliably measured without interference from atmospheric water and the method used to separate the soil clay fraction. Highlights We tested steam equilibration to determine stable isotope ratios of structural H in clay. Gas‐tight capsule sealing in Ar atmosphere was necessary to avoid remoistening. Our steam equilibration method showed a high accuracy and precision. The clay separation method did not change stable isotope ratios of structural H in clay.

Beschreibung: Soil fauna drives crucial processes of energy and nutrient cycling in agricultural systems, and influences the quality of crops and pest incidence. Soil tillage is the most influential agricultural manipulation of soil structure, and has a profound influence on soil biology and its provision of ecosystem services. The objective of this study was to quantify through meta‐analyses the effects of reducing tillage intensity on density and diversity of soil micro‐ and mesofaunal communities, and how these effects vary among different pedoclimatic conditions and interact with concurrent management practices. We present the results of a global meta‐analysis of available literature data on the effects of different tillage intensities on taxonomic and functional groups of soil micro‐ and mesofauna. We collected paired observations (conventional vs. reduced forms of tillage/no‐tillage) from 133 studies across 33 countries. Our results show that reduced tillage intensity or no‐tillage increases the total density of springtails (+35%), mites (+23%), and enchytraeids (+37%) compared to more intense tillage methods. The meta‐analyses for different nematode feeding groups, life‐forms of springtails, and taxonomic mite groups showed higher densities under reduced forms of tillage compared to conventional tillage on omnivorous nematodes (+53%), epedaphic (+81%) and hemiedaphic (+84%) springtails, oribatid (+43%) and mesostigmatid (+57%) mites. Furthermore, the effects of reduced forms of tillage on soil micro‐ and mesofauna varied with depth, climate and soil texture, as well as with tillage method, tillage frequency, concurrent fertilisation, and herbicide application. Our findings suggest that reducing tillage intensity can have positive effects on the density of micro‐ and mesofaunal communities in areas subjected to long‐term intensive cultivation practices. Our results will be useful to support decision making on the management of soil faunal communities and will facilitate modelling efforts of soil biology in global agroecosystems. HIGHLIGHTS Global meta‐analysis to estimate the effect of reducing tillage intensity on micro‐ and mesofauna Reduced tillage or no‐tillage has positive effects on springtail, mite and enchytraeid density Effects vary among nematode feeding groups, springtail life forms and mite suborders Effects vary with texture, climate and depth and depend on the tillage method and frequency

Beschreibung: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉Hydrogeological information about an aquifer is difficult and costly to obtain, yet essential for the efficient management of groundwater resources. Transferring information from sampled sites to a specific site of interest can provide information when site‐specific data is lacking. Central to this approach is the notion of site similarity, which is necessary for determining relevant sites to include in the data transfer process. In this paper, we present a data‐driven method for defining site similarity. We apply this method to selecting groups of similar sites from which to derive prior distributions for the Bayesian estimation of hydraulic conductivity measurements at sites of interest. We conclude that there is now a unique opportunity to combine hydrogeological expertise with data‐driven methods to improve the predictive ability of stochastic hydrogeological models.〈/p〉

Beschreibung: Marine Ökosysteme wie Mangrovenwälder, Seegraswiesen, Salzwiesen und Makroalgen sowie marine Sedimente verfügen über die Eigenschaft, Kohlenstoff in ihrer Biomasse und Sedimenten zu speichern. Durch die Rehabilitation, Wiederherstellung und den Schutz dieser Ökosysteme kann somit das Potential des Ozeans zur Aufnahme von atmosphärischem CO2 erhöht werden. Dieses Potential wurde in Vorbereitung der 15. UN-Klimakonferenz in Kopenhagen 2009 unter dem Konzept „Blue Carbon" eingeführt und wird seitdem weiter erforscht und in politischen Prozessen weiterentwickelt. Die langfristige Sequestrierung von atmosphärischem CO2 durch Blue-Carbon-Ökosysteme unterstützt Umsetzungsprozesse zur Erreichung der Ziele des Pariser Abkommens. Das über Blue-Carbon-Ökosysteme sequestrierte CO2 zählt als Teil der globalen Kohlenstoffsenke als „negative Emissionen". So erreichte negative Emissionen sollten jedoch nicht zur Umgehung von ohnehin notwendigen politischen und wirtschaftlichen Schritten in Richtung einer CO2-neutralen Zukunft führen. Die Wiederherstellung und Rehabilitation von Blue-Carbon-Ökosystemen zur Erhöhung der natürlichen Kohlenstoffsenke des Planeten sollte zusätzlich zu einer signifikanten globalen Emissionsreduktion eingesetzt werden. Diese Studie erörtert die wissenschaftlichen, ökonomischen und politischen Fortschritte im Bereich Blue Carbon und stellt mögliche politische Handlungspfade vor, die das Potential von Blue-Carbon-Ökosystemen zum Klimaschutz in, durch und mit Deutschland stärken. Für die verschiedenen Blue-Carbon-Ökosysteme wird aufgezeigt, inwiefern die Ausweitung und der Schutz dieser Ökosystemen weitere Ziele der Klimaanpassung und der nachhaltigen Entwicklung unterstützen. Aufbauend auf einer Auswertung praktischer Umsetzungsbeispiele von Blue-Carbon-Projekten und möglicher Finanzierungsmechanismen wird nachfolgend ein politischer Handlungsleitpfaden für Deutschland in Bezug auf Blue Carbon entwickelt. Die politischen Handlungsempfehlungen wurden gemeinsam mit dem Bundesministerium für Umwelt, Naturschutz und Nukleare Sicherheit entwickelt.

Beschreibung: Marine ecosystems like mangroves forests, seagrass meadows, salt marshes and macroalgae can store carbon in their biomass and sediments. Rehabilitation, restoration and conservation of these ecosystems can increase the potential for atmospheric carbon uptake by the ocean. This concept was first introduced as ‘blue carbon’ during the preparation for the 15th UN Climate Change Conference in Copenhagen in 2009 and since then it has seen continuous incorporation into politics and research. The long-term sequestration of atmospheric CO2 via blue carbon ecosystems supports the 1.5°C goal of the Paris Agreement. The CO2 that is sequestered by blue carbon ecosystems is part of the global carbon sink and therefore it can be counted as ‘negative emissions’ in the global carbon stocktake. However, such negative emissions should not be implemented as a substitute for necessary political and economic measures towards a carbon neutral future. Rehabilitation and restoration of blue carbon ecosystems as a natural carbon sink is one of many measures but cannot replace the significant reduction of global emissions needed for the realisation of the global climate targets. This study discusses the scientific, economic and political realm of blue carbon. Furthermore, possible courses for political action “in”, “by”, and “through” Germany that could strengthen the potential of blue carbon ecosystems to sequester carbon are explored. The study investigates a variety of blue carbon ecosystems to determine to what extent the expansion and conservation of blue carbon ecosystems can support additional climate adaptation targets and Sustainable Development Goals. The evaluation of a multitude of implemented and ongoing blue carbon projects across the globe gives insight to best practices and possible financing mechanisms. A political guideline for Germany regarding blue carbon was developed together with the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

Beschreibung: The challenges facing European regions undergoing structural transformations as they transition towards sustainable development pathways have attracted increasing interest in recent years. Straddling the border between Germany and Poland, Lusatia is experiencing considerable transformation pressure. Various domestic and European funding programmes, for example under the umbrella of the European Green Deal, are intended to cushion the impacts of the phase-out or reduction of coal-fired power generation. The recently adopted EU Just Transition Mechanism aims to support sustainable structural transformations and the broader goal of achieving climate neutrality by mitigating impacts on the workforce and contributing to the diversification of economies in the most affected areas. Funds made available through this mechanism should be deployed in consultation with regional stakeholders in Lusatia to complement national support measures. Further funding programmes are available targeting various policy areas and could be harnessed to strengthen integration throughout the region. Funding programmes that are centrally managed by the European Commission (i.e. not under shared management with national governments) are of particular interest in this context. Closer political and economic cooperation, coupled with a deeper exchange of experience, can accelerate regional integration and guide processes of structural transformation towards sustainable outcomes. However, there are some practical hurdles to overcome in border regions. The primary objectives in using available EU funding are to mitigate the social impacts of processes of structural transformation and to deliver a just transition at all levels. Measures funded through these programmes should be aligned with the sustainable development goals (SDGs) and contribute to the goal of achieving climate neutrality.

Beschreibung: This report was prepared as part of the STRONG High Seas project, based on a series of stakeholder surveys and experience gathered through various workshops held in the Southeast Pacific region, as well as on literature surveys and expert opinion. The report was reviewed by experts to validate findings and ensure robust content. This report is part of a series of reports covering issues of ocean governance with a focus on the ABNJ of the Southeast Pacific and the Southeast Atlantic regions and builds on previous reports published by the STRONG High Seas project. Further project reports cover the legal and institutional framework applicable to ABNJ, the ecological state and the socioeconomic importance of ABNJ in the project regions, options for management and conservation measures for conservation of marine biodiversity in ABNJ, and considerations for integrated ocean management. These reports are available through the STRONG High Seas project website. Following this introductory chapter, Chapter 2 provides relevant context with regards to ocean governance in areas beyond national jurisdiction, the ongoing negotiations towards a new agreement under UNCLOS and related capacity development needs and approaches. Chapter 3 presents a short summary of the surveys undertaken by the STRONG High Seas project with regards to capacity needs in the Southeast Pacific region and Chapter 4 is a summary of the corresponding capacity development efforts undertaken as part of the STRONG High Seas project. Chapter 5 provides reflections and recommendations for future capacity development activities beyond the scope of the project and highlights lessons learned through the five years of this project. Additional background information is provided in the Annexes.

Beschreibung: Local cooperation between civil society and the public sector is becoming increasingly important – in local transformation projects, in science, and occasionally in politics and administration. Commons-Public Partnerships (CPPs) provide a way to frame, promote and extend this collaboration. In civil society, CPPs are typically defined by the practice of commoning, where local communities exercise self-regulation based on the principles of community welfare and the common good. This discussion paper examines the theory and practice of commoning and other forms of cooperation. While focusing on the challenges of social-ecological transformation, the paper also identifies areas where CPPs can be implemented and highlights fields of tension exposed by the concept.

Beschreibung: Measures to support conservation efforts must put the protection of biodiversity and/or ecological integrity as the primary objective and consider cumulative pressures on the marine environment. This also means including ecological connectivity (e.g., migratory routes of marine species, transboundary impacts of human activities), and climate change impacts in their design and implementation. Moreover, the complexity and dynamic nature of the ocean, including in areas beyond national jurisdiction (ABNJ), requires that conservation efforts acknowledge uncertainty, include options to address it or adapt swiftly to new scientific information, and consider the three-dimensional space of the ocean. This also requires that the best available interdisciplinary scientific and indigenous knowledge provide the basis for the design and implementation of such measures. It will be essential that measures to support conservation efforts apply mechanisms for cross-sectoral consultation, cooperation, and collaboration, as well as consider appropriate spatial and temporal scales for implementation. They must reflect broad societal goals and consider uneven distribution of socio-economic outcomes resulting from exploitative activities in ABNJ. Governance and management actions must recognise coupled and diverse social-ecological systems, and the interconnection between ocean health and human wellbeing, including diverse stakeholder considerations in the design and implementation of the measure or approach. It is essential that the design and implementation of measures to support conservation efforts include appropriate means to ensure the regular monitoring, control, and surveillance of human activities as well as the compliance and enforcement of the laws and regulations in place. States are familiar with legal instruments, such as those under the United Nation Convention on the Law of the Sea (UNCLOS), United Nations Food and Agricultural Organisation (FAO), International Maritime Organisation (IMO) conventions, International Seabed Authority (ISA), and management measures adopted by the Regional Fisheries Management Organisations (RFMOs). They have developed governance structures and capacity to support their implementation. The recommendation in this context would be for States to support the consolidation and further development of measures to support conservation efforts with the aim to ensure that they integrate their approach with considerations for ecological connectivity, biodiversity protection, ecosystem-based integrated ocean management and climate change implications for the conservation and management of biodiversity in ABNJ. To be effective, any measures to support conservation efforts proposed for ABNJ in the Southeast Atlantic region must consider the socio-economic and political realities of the countries whose Exclusive Economic Zones border these areas. In this sense, it is important to note the important role that the fishing sector has historically played and continues to play for most economies of this region. The proposed Biodiversity Beyond National Jurisdiction (BBNJ) Instrument in negotiation at the United Nations, will be fundamental for establishing the legal basis for developing and implementing cross-sectoral measures to support conservation efforts in ABNJ. The way in which the proposed BBNJ Instrument is integrated and how the link to existing conservation and sustainable use measures established under existing management organisations is made will determine the effectiveness of the possible measures to support current and future conservation efforts. In this regard, it is particularly important for the Southeast Atlantic region how existing RFMOs will be able to interact with the proposed BBNJ Instrument. Considering the capacity (technological, experience, financial, logistical) challenges of many of the countries in the Southeast Atlantic, it is important that measures to support conservation efforts under existing international treaties or legal mechanisms be integrated, practical, and cost-effective. The different legal status of the water column and the deep seabed beyond national jurisdiction and the different legal provisions in place represent a challenge for the development of a coherent, comprehensive, and integrated approach to the conservation and sustainable use of biodiversity in ABNJ. Lack of uniformity in compliance among flag States and the lack of monitoring and enforcement mechanisms in ABNJ jeopardise the achievement of an integrated approach for conservation and sustainable use of marine biodiversity in these vast areas of ocean. The wide array of existing instruments can be used to improve conservation of biodiversity in ABNJ through improved monitoring and enforced compliance. This remains the responsibility of individual flag States, but at present there is limited reporting of vessels and minimum follow up action by flag or port States.

Beschreibung: In April 2021, under the “IMPACT R” project, IASS Potsdam and HEDERA Sustainable Solutions GmbH in Berlin, together with University of Rwanda and Sustainable Villages Foundation (SVF), conducted a household survey in two villages in Rwanda. SVF has started an integrated village development pilot project in those two villages and wanted to better understand the local populations’ needs and establish a baseline for impact measurement, in order to track the project’s progress over time. In parallel, focus group discussions and key stakeholder interviews were carried out. The main results are as follows: Over 80 % of households get their main income from agriculture, largely on small plots. Two-thirds of the households have USD 45 or less to spend on a 5-person family, on average. There is no public electricity grid. Half of the households have access to very basic electricity through solar systems; the other half has none at all. Over 90 % of households use wood and open fire pits or handmade clay stoves for cooking, mostly indoors, causing deforestation and health problems because of the smoke. There is no public or private drinking water supply. Villagers collect rainwater and/or surface water, which has to be carried over several kilometers by adults and children. The water is dirty and not treated before drinking in one-third of households, which triggers diseases. Only 26 % of households are classified as food-secure, whereas 15.5 % are above the severe food insecurity threshold. A significant percentage of the inhabitants does not eat a balanced diet due to lack of resources. The local community especially emphasized the need for: Priority 1: Safe drinking water Priority 2: Electricity Priority 3: Clean cooking devices Another severe challenge is poverty in general. There is a shortage of food in terms of quantity and quality for a significant portion of the population. This is caused by households’ limited financial capacity and insufficient agricultural yield due to the absence of water for irrigation and inefficient agricultural techniques. Furthermore, teacher qualification in English and information technology (IT) is not satisfactory, and the primary school has no electricity in most of the classrooms and no computers. Professional training options are only offered far away from the villages and are very costly. New business development is hindered by the lack of electricity. The target communities seek for support to address all the above challenges and are willing to contribute their part.

Beschreibung: This report presents a framework for the systematic monitoring of the global hydrogen economy. It suggests data sources and indicators to systematically survey the most important trends and developments of a future global hydrogen economy. Monitoring based on this framework could provide an important knowledge base for the continuous review of policy measures related to the German and European hydrogen policy.

Beschreibung: Im folgenden Bericht wird ein Konzept für ein systematisches Monitoring der globalen Wasserstoffwirtschaft vorgestellt.

Ein entsprechendes Monitoring könnte einen wichtigen Beitrag zur kontinuierlichen Überprüfung von Politikmaßnahmen im Rahmen der deutschen und europäischen Wasserstoffpolitik leisten.

Beschreibung: Deep-seabed mining in the Area is regulated by the International Seabed Authority (ISA) which is mandated to act on behalf of humankind as a whole. Consistent with international environmental law and human rights norms, in its decision making the ISA is expected to engage with its broad constituency. Using ten assessment criteria, this paper analyses the extent to which the ISA has facilitated public participation to date. This paper finds that, while the ISA has increased outreach activities, significant scope for improvement remains. Several ways to improve public participation at the ISA are identified, including (1) proactive consultation with a wider reach, including stakeholders that are hitherto not engaged; (2) mechanisms to ensure stakeholder consultations and submissions are given due consideration, and that the rationale for decisions are publicly communicated; and (3) enhanced public engagement in the implementation of decisions.

Beschreibung: La gestión integrada de los océanos (GIO) es un enfoque adaptativo de la gestión de las actividades humanas en el océano, que tiene sus raíces en el enfoque ecosistémico. Requiere la consideración de todas las dimensiones del espacio oceánico – esferas física, oceanográfica, climática, biológica, social y económica – e incluye la dinámica espacial y temporal del sistema. Su objetivo es crear un marco para una economía oceánica sostenible. Para lograr este ambicioso objetivo, los procesos de gestión deben integrarse entre la gobernanza, las partes interesadas, los conocimientos, la dinámica del sistema y ser transfronterizos, lo que constituirá los "pilares" para una integración eficaz. Las características clave del enfoque integrado propuesto para la gestión de los océanos exigen una mayor colaboración, intercambio de conocimientos, transparencia, coordinación y comunicación. Los puntos de vista y valores de la comunidad, así como los conocimientos científicos, tradicionales y locales, desempeñan un papel fundamental en la definición y puesta en marcha de los pilares mencionados. El enfoque de la GIO aún no se ha aplicado a las ABNJ, pero sí a las aguas costeras. La GIO será cada vez más importante en las ABNJ para hacer frente a los crecientes desafíos de lograr la conservación y el uso sostenible de la biodiversidad marina. Por ello, este informe pretende ofrecer una visión general de la aplicación de la GIO en el contexto de la conservación y el uso sostenible de la biodiversidad marina en las ABNJ, especialmente en las regiones del Atlántico Sudeste y del Pacífico Sudeste. En particular, pretende promover la GIO para las ABNJ en todos los sectores y dimensiones ecológicas, considerando la aplicación de condiciones propicias para lograr la cooperación y la colaboración entre los diversos actores que trabajan en las ABNJ o que las afectan. Este informe resume Resumen ejecutivo los retos actuales a los que se enfrenta la gestión de las ABNJ, identifica las oportunidades para aplicar la GIO a través de las fronteras y ofrece recomendaciones para avanzar en esta prioridad urgente, guiada por los Objetivos de Desarrollo Sostenible. Abordar la GIO en las ABNJ es especialmente pertinente en este momento, ya que los Estados están negociando un nuevo instrumento jurídicamente vinculante para la conservación y el uso sostenible de la biodiversidad marina en las ABNJ (denominado en este informe Acuerdo BBNJ). Por lo tanto, existe la oportunidad de que los Estados incorporen disposiciones que permitan que el mecanismo sea plenamente operativo en el marco del Acuerdo BBNJ una vez que éste sea adoptado y ratificado. Este informe abarca los conceptos de la GIO, sus pilares, la importancia de la GIO para la conservación y el uso sostenible de la biodiversidad marina en las ABNJ y las oportunidades de reforzar la GIO para la conservación de la BBNJ en las dos regiones focales del proyecto STRONG High Seas: el Atlántico Sudeste y el Pacífico Sudeste. Tras analizar las oportunidades en estas dos regiones, este informe destaca algunas vías claras por las que este enfoque integrado puede apoyar significativamente la conservación de la biodiversidad en ABNJ. A continuación, se incluyen algunas recomendaciones de este informe. Para un conjunto más completo de posibles acciones y decisiones que podrían adoptar una serie de actores para mejorar la GIO, véase Table 2 en el capítulo 3.

Beschreibung: The high volume of plastic packaging currently consumed in Germany poses a complex socio-ecological risk. As part of the BMBF-funded ENSURE research consortium, environmental psychologists at the Institute for Advanced Sustainability Studies (IASS) in Potsdam have studied various policy options to promote a reduction in individual consumption of plastic food packaging. A representative nationwide survey of 1,200 persons conducted by the researchers shows that 92 per cent of the interviewed consumers consider plastic waste in the environment a threat to the preservation of our natural resources and the foundations of life. Despite this widespread awareness, the consumption of plastic packaging continues to grow: In 2018, Germany generated over three million tonnes of plastic packaging waste; more than double the amount produced in 1997. The findings of the ENSURE project indicate that consumers are willing and indeed wish to reduce their consumption of plastic packaging; however, they are hindered by personal and structural barriers. Political action is needed to break down these barriers to change and support consumers in their efforts. This IASS Policy Brief presents three strategic policy recommendations that could help reduce the consumption of packaging in daily life. Following an outline of the broader context and key issues, these three recommendations are explained in detail. In conclusion, we highlight the need for a systemic approach to the reduction of plastic packaging.

Beschreibung: This report aims to showcase and assess the participative multi-stakeholder approach used in the STRONG High Seas project to co-develop and co-design activities and outputs such as scientific assessments and capacity development programs. In particular, the report provides reflections from the project team on the numerous lessons learned during the project duration on participative multi-stakeholder approaches in transdisciplinary ocean governance research, such as designing and implementing effective engagement strategies, designing targeted capacity development programmes, and fostering co-creative research processes for supporting decision-making and achieving policy impact. The reflections on and recommendations for participative multi-stakeholder approaches within transdisciplinary ocean governance research gained through the course of the STRONG High Seas project can be found in Chapter 3.

Beschreibung: This COBENEFITS report gives an overview of enabling policies that have high potential to make fair use of the maximum potential of co-benefit opportunities that can be unlocked by following the pathway of a high share of renewable energies in the power sector. They are presented according to the different COBENEFITS categories. Enabling policies for renewable energy (RE) cobenefits and their specification and implementation are highly context-specific. They need to take into account the context of the country or region they are planned for, and need to be tailored to remove specific barriers preventing communities from unlocking them. Therefore, each enabling policy option presented in this report is accompanied by a short summary of an initial situation that they might solve or improve.

Beschreibung: In the last years, the concept of tipping points received increasing recognition in social science and rose on the political agenda. Identifying tipping points would allow researchers to identify the point in time in which a transition happens, and to understand the processes of overcoming lock-in mechanisms and trigger deliberate tipping an existing system into a qualitatively new state. Because tipping points bring about rapid systemic change, it is desirable to further understand how tipping points may be triggered to accelerate the transformation of social and economic systems. There is little doubt that tipping points exist in both social and socio-technical systems because we can observe that systems and societies are fundamentally different today than they were in the past. However, despite a growing body of literature, there remain many open questions how to conceptualise and ultimately operationalize social tipping points. This also stems from a lack of empirical studies and insights observing tipping points in social contexts. In the Tipping.Plus project we addressed this gap with a literature review and empirical case studies investigating tipping dynamics from a public policy and governance perspective. In the literature review we explored definitions, characteristics, and the application of the concept and notion of tipping points in political and governance theories and contexts. In the second step, we conducted an empirical study investigating the socio-economic transition processes of the two German neigbouring cities Essen and Duisburg, which have both phased out their coal industries, as part of the wider structural change in the Ruhr Region. We focused on (political) interventions and their effects on the cities’ development trajectories in the last 30+ years to identify differences in outcome as a function of policy interventions and/or contextual differences. Apart from identifying the key development drivers, we investigate whether either city crossed a tipping point in their transition process (yet), away from coal towards a low carbon but still prosperous future (Mey and Lilliestam 2022). In the following we synthesise the findings of this work and our observations and experiences in order to contribute to the overall Tipping.Plus Integration Framework and Social Theory on social tipping points in energy transitions.

Beschreibung: Research undertaken in Task 2.2 identified a range of governance challenges to ocean-based NETs related to the global ocean governance framework, e.g., linked to the transboundary nature of the ocean, potential effects of ocean-based NETs on the ocean’s condition and marine ecosystem services, as well as the many unknowns and uncertainties linked to NET-deployment. The fragmented approaches and frameworks in place to govern the global ocean further complicate comprehensive governance of these emerging technologies. This deliverable presents results from a workshop that explored how ocean-based NETs should be governed to best confront these challenges and integrate international climate targets as well as global goals for ocean and biodiversity conservation, in addition to global ambitions towards sustainable development. The workshop is part of research undertaken by Task 2.2 to assess how ocean-based NETs are addressed by the current global ocean governance framework and develop governance scenarios and recommendations to policy makers for a “good governance” of NETs in the ocean.

Beschreibung: Die Arktis erwärmt sich substanziell schneller als der globale Durchschnitt. Der rasche Temperatur-anstieg verändert die Arktis bereits tiefgreifend - und wird dies auch weiterhin tun - mit noch unbekannten Folgen für die Region und die ganze Welt. Gleichzeitig mit dem Rückgang des Meereises und der sich verändernden Verteilung der lebenden Meeresressourcen hat eine Zunahme des wirtschaftlichen Interesses an der Region zu Bedenken hinsichtlich der Nachhaltigkeit der wirtschaftlichen Aktivitäten in der Arktis geführt. Um Wege zu finden, wie der Schutz und die nachhaltige Nutzung der arktischen Meeresumwelt gewährleistet werden können, ist ein umfassendes Verständnis der Meeresumwelt, der sie beeinflussen-den Belastungen und der relevanten Regulierungen und Managementmaßnahmen erforderlich. DasEcologic Institut und das Institute for Advanced Sustainability Studies haben sich zum Ziel gesetzt, durch eine Reihe von Berichten zum Meeresschutz in der Arktis einen Überblick über die relevantenInformationen zu geben. Die Berichte konzentrieren sich auf die fünf arktischen Anrainerstaaten: Ka-nada, Dänemark (durch Grönland), Norwegen, die Russische Föderation und die Vereinigten Staaten.Darüber hinaus gibt ein regionaler Bericht einen umfassenden Überblick und fasst die einschlägigen internationalen und regionalen Vorschriften zusammen. Der vorliegende Bericht behandelt die für den Meeresschutz in der russischen Arktis relevanten Informationen. Der Bericht deckt vier Hauptthemen ab: Er beginnt mit der Beschreibung der wichtigstenMerkmale der Meeresumwelt der russischen Arktis. Anschließend werden wesentlichen Belastungen untersucht, die sich auf die marine Biodiversität in der Region auswirken, gefolgt von einer Untersuchung der soziokulturellen und wirtschaftlichen Rolle sowie der Umweltauswirkungen der wichtigsten meeresbezogenen menschlichen Aktivitäten in der russischen Arktis. Der letzte Teil des Berichts gibt einen Überblick über die relevanten nationalen Institutionen sowie über Regulierungen, Vorschriften und Instrumente, die zum Schutz der russischen arktischen Meeresbiodiversität und zur Gewährleistung ihrer nachhaltigen Nutzung eingesetzt werden oder eingesetzt werden könnten. Hinweis: Die in diesem Bericht präsentierten Informationen wurden hauptsächlich während der weltweiten Covid-19-Pandemie und vor dem russischen Einmarsch in die Ukraine im Jahr 2022 zusammengetragen. Die (weiteren) politischen und wirtschaftlichen Auswirkungen dieser Ereignisse und dies ich daraus ergebenden Veränderungen in der Arktis-Governance sind zum jetzigen Zeitpunkt nichtabsehbar, und es ist zu erwarten, dass sich einige der in diesem Bericht dargestellten Entwicklungen und Trends erheblich ändern werden. Die Kernbotschaften des Berichts finden sich unter der folgenden englischen Zusammenfassung.

Beschreibung: Global interest and activity in the Arctic have increased greatly in recent decades. The Arctic is warming three times faster than the global average. These rapidly increasing temperatures are already profoundly changing – and will continue to change – the Arctic, with yet unknown consequences for the people, environment, and economy in the region as well as worldwide (SDWG, 2021). The diminishing sea ice extent and the changing distribution of marine living resources have led to an increase in economic interest in the region as well as concerns about the sustainability of economic activities in the Arctic (Raspotnik et al., 2021). The challenge now is to identify development pathways that can ensure the sustainable use and conservation of the Arctic marine environment (SDWG, 2021). In order to identify ways in which conservation and sustainable use of the Arctic marine environment can be ensured, a broad understanding of the marine environment, the pressures affecting it, and the relevant regulations is needed. Ecologic Institute and the Institute for Advanced Sustainability Studies aim to provide an overview of relevant information through a series of reports on marine conservation in the Arctic. The reports focus on the five Arctic coastal states: Canada, Denmark (by virtue of Greenland), Norway, the Russian Federation, and the United States. In addition, a regional report is providing a broader overview and summarises relevant international and regional regulations. The reports were published in 2022 and are available for download on the websites of the Ecologic Institute and the Institute for Advanced Sustainability Studies. This current report presents an overview of information relevant to marine conservation in the Russian Arctic. The report covers four main issues: it starts with the description of the key characteristics of the Russian Arctic marine environment. Then it examines significant pressures impacting marine biodiversity in the region, followed by exploring the socio-cultural and economic role as well as the environmental impact of the main sea-based human activities in the Russian Arctic. The last part of the report describes the Russian ocean governance system and provides an overview of relevant national institutions as well as rules, regulations and tools which are, or could be, employed to protect marine biodiversity in this region and ensure its sustainable use. NB: The information presented in this report was mainly collated during the global Covid-19 pandemic and prior to the 2022 Russian invasion of Ukraine. The (further) political and economic impacts of these events and resulting changes in Arctic governance cannot be foreseen at this point in time and it can be expected that some of the developments and trends presented in this report may change substantially.

Beschreibung: Este informe – Estudio sobre medidas para apoyar esfuerzos de conservación en áreas fuera de la jurisdicción nacional en la región del Pacífico Sudeste – pretende proporcionar recomendaciones para la conservación y uso sostenible de la biodiversidad marina en áreas fuera de la jurisdicción nacional (ABNJ, por sus siglas en inglés) en la región del Pacífico Sudeste. Estas recomendaciones incluyen consideraciones para establecer nuevas medidas de conservación y manejo y expandir o mejorar en la región otras medidas existentes; así como el uso de herramientas que apoyan el desarrollo de medidas de conservación. Este informe ha sido elaborado por investigadores del proyecto STRONG High Seas a partir de una revisión bibliográfica de artículos académicos, análisis de datos, conocimientos de las partes interesadas y experiencias recogidas en talleres de expertos celebrados en la región de interés del proyecto en 2021. La información presentada aquí pretende apoyar a tomadores de decisiones, incluyendo funcionarios de los gobiernos, el sector privado y otras partes interesadas que trabajen en el tema de la gobernanza oceánica en ABNJ y que participen o tengan interés en el actual desarrollo de la Conferencia Intergubernamental sobre un instrumento internacional jurídicamente vinculante en el marco de la Convención de las Naciones Unidas sobre el Derecho del Mar (CONVEMAR) relativo a la conservación y el uso sostenible de la diversidad biológica marina de las áreas fuera de la jurisdicción nacional (BBNJ, por sus siglas en inglés). Este informe hace parte de una serie de informes publicados por el proyecto STRONG High Seas [Strengthening Regional Ocean Governance for the High Seas (June 2017 – May 2022)], que cubren aspectos de la gobernanza de los océanos con un foco geográfico en la región del Pacífico Sudeste (y el Atlántico Sudeste).

Beschreibung: In diesem Beitrag wird das aktuelle Interesse der politischen und wirtschaftlichen Entscheidungsträger in den öl- und gasproduzierenden Staaten des Golf-Kooperationsrates (GCC) an der Wasserstoffenergie untersucht. Obwohl die Hauptakteure die fossilen Energieträger, die die politische Ökonomie der Region seit Jahrzehnten bestimmen, weiterhin stärken, erkennen sie zunehmend, dass sich das Zeitalter der Kohlenwasserstoffe dem Ende zuneigt. Dies hat zu einer Zunahme verschiedener "Post-Öl"-Energieinvestitionen geführt, zu denen in letzter Zeit auch Wasserstoff gehört. In diesem Diskussionspapier wird untersucht, warum dies der Fall ist, d. h. warum die politischen und unternehmerischen Spitzen des Golf-Kooperationsrates (GCC) an der Förderung von Wasserstoffenergiesystemen in der Region interessiert sind. Es wird gezeigt, dass die Bestrebungen zur Herstellung von "grünem" Wasserstoff - die ihren Ursprung in Europa und insbesondere in Deutschland haben - zunehmend als eine Möglichkeit gesehen werden, den grünen Ruf der Region zu verbreiten und gleichzeitig Investitionen in "blauen" Wasserstoff zu unterstützen, die von den staatlichen Öl- und Gasriesen in den Vereinigten Arabischen Emiraten (VAE) und Saudi-Arabien gefördert werden.

Beschreibung: Dieses Paper behandelt Barrieren und positive Einflussfaktoren auf persönliches und öffentliches Engagement für Klimaschutz. Der Erfolg von ambitionierter Klimaschutzpolitik hängt in Demokratien von gesellschaftlicher Zustimmung und Ownership für die unternommenen Maßnahmen ab. AktivistInnen und EntscheidungsträgerInnen müssen ihre Ideen auf eine Weise kommunizieren, die die Menschen anspricht und sie aufrüttelt. Um dabei Erfolg zu haben, muss zunächst verstanden werden, was Menschen zum Handeln motiviert und was sie daran hindert. Dieses Paper trägt zur Beantwortung dieser Fragen bei, indem es einen Überblick über Theorien der Psychologie und der Kommunikationswissenschaft über die kognitiven Tendenzen gibt, die eine logische Entscheidungsfindung behindern. Anschließend wird eine Alternative zum weitverbreiteten „Angstaufruf“ in der Klimawandelkommunikation vorgeschlagen: ein positives, chancenorientiertes Framing, das mit den Werten der Menschen im Einklang steht und das Potenzial hat, langfristiges Engagement für nachhaltige Maßnahmen anzuregen. Schließlich wird aufgezeigt, wie das sogenannte Co-benefits Framing in der Politik genutzt werden kann.

Beschreibung: Jordan’s energy transition has been rapid and ambitious: in 2021 renewables accounted for 26 % of electricity production in Jordan, up from less than 1 % in 2014. This massive leap forward was prompted by energy security concerns in the wake of the Arab Spring that forced the government to scramble for alternatives to Egyptian gas. Today, Jordan is a regional clean energy industry frontrunner, with over 300 PV companies and around 13 000 employees in the sector. However, recent policy decisions have stalled further progress. Auctions for new projects have been scaled back or postponed, and new ventures in excess of 1 MW were indefinitely suspended in January 2019. At the same time, changes to electricity tariff structures have dampened demand for residential PV. This loss of momentum is largely due to financial constraints on Jordan’s state-owned National Electric Power Company (NEPCO), which is caught in long-term purchasing agreements for fossil fuels that conflict with the goal of growing Jordan’s renewable energy sector and are exacerbating NEPCO’s already significant debt burden. With 20 % of public debt linked to the electricity sector, this also has ripple effects for the rest of the Jordanian economy. Increased regional cooperation will be needed to re-negotiate Jordan’s commitments to purchase fossil fuels and to expand the regional market for renewable energy, allowing Jordan to export surplus electricity and establish itself as a clean energy hub while at the same time giving neighbours the chance to sell energy elsewhere and increasing regional stability. And while Jordan’s top-down approach to energy policy was crucial to driving the rapid growth of renewables, the current risk of stalling progress makes it clear that stakeholders from different ministries as well as industry and civil society must be involved in future policy development processes to accelerate Jordan’s energy transition and shift the country from the current single-buyer model towards a more competitive market for electricity.

Beschreibung: Die lokale Zusammenarbeit von organisierter Zivilgesellschaft und öffentlicher Hand gewinnt zunehmend an Bedeutung: in lokalen Transformationsprojekten, in der Wissenschaft und vereinzelt auch in Politik und Verwaltung. Commons-Public Partnerships (CPPs) bieten eine Möglichkeit, diese Zusammenarbeit zu rahmen, zu fördern und auszuweiten. Auf Seite der Zivilgesellschaft zeichnen sich CCPs durch die Praxis des Commoning aus, also gemeinschafts- wie gemeinwohlorientierte Praktiken der lokalen Selbstorganisation. Im vorliegenden Diskussionspapier wird sowohl das Commoning als auch die Form der Kooperation konzeptuell und in der Praxis verortet. Mit einem Fokus auf die Herausforderungen der sozialökologischen Transformation werden Potenzialfelder für den Einsatz von CPPs identifiziert. Darüber hinaus werden konzeptuelle Spannungsfelder beleuchtet.

Beschreibung: Carbon capture and utilization (CCU) or CO2 utilization technologies attract researchers, policy makers, and industry actors in search of sustainable solutions for industrial processes. This increasing interest can be explained by the fact that these processes comprise the capturing of CO2 – the most relevant greenhouse gas (GHG) – from the air or industrial point sources, and promote its use as a feedstock for the production of goods. CCU processes are expected to contribute to the greenhouse gas neutrality targets of several industrial sectors and the development of a circular economy. Therefore, understanding the environmental impacts and economics of CO2 utilization routes is essential for decision makers from relevant fields, such as technology developers, entrepreneurs, funding agencies, policy makers, administrators and more. A deep understanding of the specific implications of CO2 utilization technologies is needed to make decisions in line with sustainability strategies, and to discard inappropriate solutions. The ‘Techno-Economic Assessment & Life Cycle Assessment Guidelines for CO2 Utilization’1 (henceforth TEA and LCA Guidelines) published by the Global CO2 Initiative (GCI) in October 2018, represent a milestone in the harmonization of Life Cycle Assessment (LCA) and Techno-Economic Assessment (TEA) for evaluating CCU technologies. Henceforth, we refer to this document as TEA and LCA Guidelines. The TEA and LCA Guidelines provide a guide to overcoming methodological discrepancies that lead to confusion among practitioners, concerning how to conduct assessments, and which often lead to contradictory results.2 3 Documents with a similar focus have also been published by the National Energy Technology Laboratory (NETL).4 The success of the GCI publication and the demand for such guidelines is evidenced by the strong response that the authors registered in the months following its publication: more than 2,000 copies of the TEA and LCA Guidelines have been distributed in digital form or hard copy, and a growing community of practitioners, and decision makers from science, industry, and public administration are learning how to generate robust and comparable assessments when evaluating CCU technologies. In addition to the guidelines and the present report, the same research group has recently released five illustrative worked examples5 to support the application of the TEA and LCA Guidelines, and three accompanying peer-reviewed articles.6 At the same time, policy officers at national and international levels have frequently signaled the urgency of further developing these tools, to enable evaluation of innovative technologies as a basis for decision making in funding and policy design (e.g., the EU Innovation Fund). Despite the urgent need to address planetary climate change, the development and diffusion of new technologies often takes considerable time. Consequently, leveraging the current momentum amongst all involved actors that CCU has achieved to date is paramount and is an opportunity that must not be missed. Despite demands for aligned assessment methods from the industrial and policy spheres,7 there are evident challenges in dealing with the practical application of such methods in commissioning, reading, and interpreting LCA and TEA studies. There is also a risk of insufficient transfer into policy or other decision-making processes, in cases where the involved actors do not possess disciplinary expertise in the relevant methodology.

Beschreibung: In this paper, we investigate the socio-economic transition processes of Essen and Duisburg as part of the wider structural change in the Ruhr Region. In the two case studies, we explore causes and effects of the cities’ development trajectories in the last 30+ years, seeking to identify differences in outcome as a function of the interventions and/or contextual differences. We analyse events, interventions and their impacts on the social and economic systems of the two cities across time. Apart from identifying the key development drivers, we investigate whether either city crossed a tipping point in their transition process (yet), away from coal towards a low-carbon but still prosperous future. Therefore, we specifically evaluate the cities’ development trajectories by seeking evidence for “no”, “incremental” or “radical” changes in a set of indicators. Here, we have taken a long temporal perspective, because trajectories of and trajectory changes in social systems are specifically visible in demographic dynamics, economic structures and political arrangements across time.

Beschreibung: Die Arktis erwärmt sich substanziell schneller als der globale Durchschnitt. Der rasche Temperatur-anstieg verändert die Arktis bereits tiefgreifend - und wird dies auch weiterhin tun - mit noch unbekannten Folgen für die Region und die ganze Welt. Gleichzeitig mit dem Rückgang des Meereises und der sich verändernden Verteilung der lebenden Meeresressourcen hat eine Zunahme des wirtschaftlichen Interesses an der Region zu Bedenken hinsichtlich der Nachhaltigkeit der wirtschaftlichen Aktivitäten in der Arktis geführt.

Beschreibung: Ernährung ist zentral für die sozial-ökologische Transformation und dabei ein für Bürger:innen zugängliches Alltagsthema. Einige Städte und Gemeinden in Deutschland und Frankreich haben das Potenzial einer innovativen lokalen Politik für nachhaltige Ernährung erkannt und spannende Ansätze entwickelt und erprobt. Dabei stoßen sie jedoch auf strukturelle Barrieren, die nicht auf der kommunalen Ebene zu beseitigen sind. Das Deutsch-Französische Zukunftswerk hat zu den Chancen und Hemmnissen lokaler Ernährungswenden recherchiert und engagierte Kommunen beider Länder miteinander in Austausch gebracht. Gemeinsam mit Expert:innen aus der Wissenschaft, Verwaltung und Zivilgesellschaft hat es darüber hinaus die Handlungsempfehlung „Entwicklung lokaler und nachhaltiger Ernährungssysteme priorisieren“ mit fünf Aktionsvorschlägen an die nationalen Regierungen entwickelt. Diese Studie versteht sich als Hintergrundpapier zur Handlungsempfehlung. Anhand des konkreten Beispiels von Mouans-Sartoux und anderen Kommunen beschreibt es die Potenziale einer nachhaltigen kommunalen Ernährungspolitik und liefert – aus der konkreten lokalen Praxis heraus – das Hintergrundwissen für jeden der fünf Aktionsvorschläge.

Beschreibung: Food and food policy is central to social-ecological transformation. It is also an everyday issue that is easy to communicate to citizens. Municipalities in Germany and France have recognized the potential of innovative local food policies and have developed and tested innovative approaches to transforming local food systems. However, they are encountering structural barriers that cannot be overcome at the municipal level. The Franco-German Forum for the Future has researched the opportunities and obstacles of local nutritional change and brought engaged municipalities from both countries into exchange with each other. Together with experts from academia, public administrations and civil society, it has developed the seven recommendations for the national governments, one of which concerns "Prioritizing the development of local and sustainable food systems" with five proposals for action. This study is intended as a background paper to the Recommendation. With recourse to the concrete example of Mouans-Sartoux and other municipalities in France and Germany, it describes the potentials of a sustainable municipal food policy and provides – from concrete local practice – the background knowledge for each of the five proposals for action.

Beschreibung: Deliberative Mini-Publics (DMPs) employ randomly selected groups of citizens, who work together to develop recommendations on specific issues. In democratic practice, DMPs, which include Citizens’ Assemblies, Citizens’ Councils, Deliberative Panels, Citizens’ Jury, etc., are usually called into action by policymakers to complement representative decision-making. The following describes how DMPs work, why they are used, and what determines their success.

Beschreibung: Kenya is a climate and renewable energy frontrunner in the sub-Saharan region. The country is committed to decarbonisation and currently aims to reduce greenhouse gas emissions by 32 % by 2030, relative to the business-as-usual scenario. Kenya has rapidly increased electrification access over the last decade thanks to a strong on- and off-grid renewable energy sector. Electricity from renewable sources covered 88 % of total domestic demand in 2020. The bulk of this is generated using geothermal energy, followed by hydro and wind power. These are complemented by a growing solar PV sector. Despite this laudable progress and the introduction of policies to foster renewables, the energy sector still faces significant challenges, including a lack of universal access, affordability issues and limitations in the transmission and distribution network. These circumstances result in a capacity surplus of generated electricity that cannot be absorbed by demand. Recent discoveries of oil and gas reserves risk derailing efforts to decarbonise the energy sector unless the Kenyan government strengthens its current course. This policy brief identifies three key areas for action to enhance energy security and continue on a sustainable energy path: Recommendation 1: Improve the quality of the grid Kenya should bolster its digitalisation efforts, support the adoption of new technologies, invest in research to reduce inefficiencies, foster regional integration to increase connectivity, and implement demand scheduling mechanisms to harness the advantages of different energy sources. These efforts should be flanked by an update of the national grid code. Recommendation 2: Liberalise the electricity market The procurement process needs to remain competitive and based on least cost criteria. Net metering programmes and renewables auctions should be implemented in order to attract more players and investment. Improved regulations about public-private partnerships and power purchase agreements will be needed to remove bottlenecks for market entry and establish an equal playing field. These measures should be accompanied by open consultations to ensure public participation and improve the investment climate. Recommendation 3: Promote decentralised energy supply options Decentralised renewable energy generation should be promoted to ensure that off-grid consumers can access affordable, reliable, and secure energy. Kenya should enhance sustainable financing structures and improve tax incentives for technology development and distribution of decentralised energy options. Capacity building efforts should target local communities, domestic companies, and government agencies to facilitate the maintenance and administration of off-grid systems and increase their sustainability.

Beschreibung: Integrated ocean management (IOM) is an adaptive approach to managing human activities in the ocean, which is rooted in the ecosystem approach. It requires all dimensions of ocean space to be considered – physical, oceanographic, climatic, biological, social, economic spheres – and includes spatial and temporal dynamics of the system. It aims to create a framework for a sustainable ocean economy. To achieve this ambitious aim, management processes need to be integrated across governance, stakeholders, knowledge, system-dynamics, and be trans- boundary, which will form the ‘pillars’ for effective integration. Key features of the proposed integrated approach to ocean management call for enhanced collaboration, knowledge sharing, transparency, coordination, and communication. Community views and values, and scientific, traditional, and local knowledge play key roles in defining the design and operationalization of the above-mentioned pillars. The IOM approach has yet to be applied to ABNJ but is commonly applied to coastal waters. IOM will be increasingly important in ABNJ for addressing the rising challenges of achieving conservation and sustainable use of marine biodiversity. This report therefore aims to provide an overview on the application of IOM in the context of the conservation and sustainable use of marine biodiversity in ABNJ, particularly within the Southeast Atlantic and Southeast Pacific regions. It particularly aims at promoting IOM for ABNJ across sectors and ecological dimensions by considering the application of enabling conditions to achieve cooperation and collaboration between the various actors working in or affecting ABNJ. This report summarises the current challenges facing management of ABNJ, identifies opportunities to implement IOM across boundaries and provides recommendations for moving forward on this urgent priority, guided by the Sustainable Development Goals. Addressing IOM in ABNJ is particularly relevant at this point in time as States are negotiating a new legally binding instrument for the protection and sustainable use of marine biodiversity in ABNJ (referred to in this report as the BBNJ Agreement). Therefore, an opportunity exists for States to embed provisions that will allow IOM to be fully operational in the framework of the BBNJ Agreement upon its adoption and ratification. This report covers the concepts of IOM, its pillars, the importance of IOM for the conservation and sustainable use of marine biodiversity in ABNJ and the opportunities for strengthening IOM for BBNJ conservation in both STRONG High Seas project focal regions: the Southeast Atlantic and the Southeast Pacific. After analysing opportunities in these two regions, this report highlights some clear pathways by which this integrated approach can significantly support the conservation of biodiversity in ABNJ. Selected recommendations from this report are included below. For a more thorough set of possible actions and decisions that could be adopted by a range of actors to improve IOM, see Table 2 in Chapter 3.

Beschreibung: This paper examines the recent interest in hydrogen energy among political and economic leaders in the oil and gas producing states of the Gulf Cooperation Council (GCC). Although key stakeholders continue to reinforce the fossil fuel systems that have defined the region’s political economy for decades, they increasingly recognize that the hydrocarbon era is drawing to a close. This has led to an increase in various “post-oil” energy investments, which most recently include hydrogen energy. This discussion paper examines why this is the case – that is, why the GCC’s political and corporate leaders are keen on promoting hydrogen energy systems in the region. It shows that the aspiration to produce “green” hydrogen – originating in Europe and Germany in particular – is increasingly seen as a way to broadcast the region’s green credentials, while simultaneously supporting the investments in “blue” hydrogen promoted by the state-owned hydrocarbon giants in the UAE and Saudi Arabia.

Beschreibung: Les mesures visant à soutenir les efforts de conservation doivent faire de la protection de la biodiversité et/ou de l’intégrité écologique leur principal objectif et prendre en compte les pressions cumulatives sur l’environnement marin. Cela implique également d’inclure la connectivité écologique (par ex. les voies de migration des espèces marines ou les impacts transfrontaliers des activités humaines) et les impacts du changement climatique dans leur conception et leur mise en œuvre. En outre, la complexité et la nature dynamique de l’océan, notamment dans les zones situées au-delà de la juridiction nationale (ZAJN), exigent que les efforts de conservation reconnaissent l’incertitude, incluent des options pour y faire face ou s’adapter rapidement aux nouvelles informations scientifiques, et tiennent compte de l’espace tridimensionnel de l’océan. Cela nécessite également que la conception et la mise en œuvre de ces mesures s’appuient sur les meilleures connaissances interdisciplinaires scientifiques et autochtones disponibles. Il sera essentiel que les mesures visant à soutenir les efforts de conservation appliquent des mécanismes de consultation, de cooperation et de collaboration intersectorielles, et qu’elles tiennent compte des échelles spatio-temporelles appropriées pour leur mise en œuvre. Elles doivent refléter des grands objectifs sociétaux et tenir compte de la répartition inégale des retombées socio-économiques découlant des activités d’exploitation dans les ZAJN. Les actions de gouvernance et de gestion doivent reconnaître les systèmes socio-écologiques associés et diversifiés, ainsi que l’articulation entre la santé des océans et le bien-être humain, en intégrant les préoccupations des différentes parties prenantes dans la définition et la mise en œuvre de la mesure ou de l’approche. Il est essentiel que la conception et la mise en œuvre des mesures visant à soutenir les efforts de conservation comprennent des moyens appropriés pour assurer le suivi, le contrôle et la surveillance réguliers des activités humaines, ainsi que le respect et l’application des lois et règlements en vigueur. Les États connaissent bien les instruments juridiques, tels que ceux de la Convention des Nations unies sur le droit de la mer (CNDUM), de l’Organisation des Nations unies pour l’Alimentation et l’Agriculture (FAO, par son acronyme en anglais), des conventions de l’Organisation maritime internationale (OMI), de l’Autorité internationale des fonds marins (ISA, par son acronyme en anglais), ainsi que les mesures de gestion adoptées par les organisations régionales de gestion de la pêche (ORGP). Ils ont développé des structures et des capacités de gouvernance pour soutenir leur mise en œuvre. Dans ce contexte, il est recommandé aux États de soutenir la consolidation et le développement des mesures visant à soutenir les efforts de conservation, afin de s’assurer qu’elles inscrivent leur approche dans le cadre de considérations relatives à la connectivité écologique, à la protection de la biodiversité, à la gestion intégrée des océans fondée sur les écosystèmes et aux implications du changement climatique pour la conservation et la gestion de la biodiversité dans les ZAJN. Pour être efficace, toute mesure visant à soutenir les efforts de conservation proposés pour les ZAJN dans la région de l’Atlantique du Sud-Est doit tenir compte des réalités socio-économiques et politiques des pays dont les zones économiques exclusives bordent ces espaces. En ce sens, il est important de noter le rôle considérable que le secteur de la pêche a historiquement joué et continue de jouer pour la plupart des économies de cette région. La proposition d’instrument relatif à la biodiversité marine des zones situées au-delà de la juridiction nationale (BZAJN), en cours de négociation aux Nations unies, sera fondamentale pour établir la base juridique du développement et de la mise en œuvre de mesures intersectorielles visant à soutenir les efforts de conservation dans les ZAJN. L’efficacité des mesures envisageables pour soutenir les efforts de conservation actuels et futurs dépendra du mode d’intégration de l’instrument BZAJN proposé et de son articulation avec les mesures de conservation et d’utilisation durable établies dans le cadre des organisations de gestion existantes. À cet égard, il est particulièrement important pour la région de l’Atlantique du Sud-Est de savoir comment les ORGP existantes pourront interagir avec l’instrument BZAJN proposé. Compte tenu des difficultés en termes de capacité (technologique, expérience, financière, logistique) de nombreux pays de l’Atlantique du Sud-Est, il est important que les mesures visant à soutenir les efforts de conservation dans le cadre des traités internationaux ou des mécanismes juridiques existants soient intégrées, pratiques et rentables. Le statut juridique différent de la colonne d’eau et des grands fonds marins au-delà de la juridiction nationale et les différentes dispositions juridiques en place représentent un défi pour le développement d’une approche cohérente, complète et intégrée de la conservation et de l’utilisation durable de la biodiversité dans les ZAJN. Le manque d’uniformité dans le respect des règles entre les États du pavillon et l’absence de mécanismes de surveillance et d’application dans les ZAJN compromettent la réalisation d’une approche intégrée pour la conservation et l’utilisation durable de la biodiversité marine dans ces vastes zones océaniques. La grande variété d’instruments existants peut être utilisée pour améliorer la conservation de la biodiversité dans les ZAJN grâce à une meilleure surveillance et une application plus stricte des règles. Cette responsabilité reste celle de chaque État du pavillon, mais à l’heure actuelle, cela se limite au signalement des navires et à une action de suivi minimale de la part des États du pavillon ou du port.

Beschreibung: The STRONG High Seas project has published a guidance document to support the implementation of the international legally binding instrument for the conservation and sustainable use of marine biodiversity beyond national jurisdiction (BBNJ Agreement) that is being negotiated under the United Nations. This work is framed in the context of achieving spatial conservation measures but draws on examples from other biodiversity conservation efforts and offers guidance for achieving binding measures for any matter, in any regional fisheries management organisation (RFMO). Aspirations for achieving biodiversity conservation using enforceable, area-based management tools (ABMTs) in an RFMO will require dedicated action if they are to move from aspirations to actuality. Getting legally binding measures for areas beyond national jurisdiction approved and enforced in an RFMO is a complex, multi-stage process. The guidance document offers insights and strategic considerations on how to achieve biodiversity conservation outcomes in an RFMO and have such measures adopted (i.e. made legally binding). It is a distillation of personal experiences including successes, failures, and insights into some of the more arcane aspects of RFMOs’ functioning, derived from the authors’ participation in dozens of meetings at many RFMOs.

Beschreibung: This report - Study on Measures to Support Conservation Efforts in Areas Beyond National Jurisdiction in the Southeast Pacific Region - aims to provide recommendations for the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction (ABNJ) in the Southeast Pacific region. These recommendations include considerations for establishing new conservation and management measures and expanding or improving existing measures in the region, as well as the use of tools to support the development of conservation measures. This report has been prepared by STRONG High Seas project researchers based on a literature review of cademic articles, data analysis, stakeholder insights, and experiences gathered at expert workshops held in the project’s focus regions in 2021. The information presented here is intended to support decision-makers, including government officials, the private sector and other stakeholders working on ocean governance in ABNJ who are involved or have an interest in the ongoing development of the Intergovernmental Conference on an international legally binding instrument under the United Nations Convention on the Law of the Sea (UNCLOS) on the conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction (BBNJ). This report is part of a series of reports published by the STRONG High Seas project [Strengthening Regional Ocean Governance for the High Seas (June 2017 - May 2022)], covering aspects of ocean governance with a geographic focus on the Southeast Pacific (and Southeast Atlantic) region.

Beschreibung: Malaysia has set ambitious targets to increase the share of renewable energy (RE) in its energy mix. In 2021, the Ministry of Energy and Natural Resources of Malaysia (KeTSA) established an aspirational target for national installed RE capacity of 3 1% by 2025.1 This aspiration was recently reaffirmed by the National Energy Policy 2022 – 20402, which lays out a long-term plan for Malaysia’s green future. Although the country has abundant solar, biomass, and hydro resources for clean energy production, a number of barriers are slowing the energy transition. With its economy heavily reliant on fossil fuels, Malaysia risks a carbon lock-in that would perpetuate existing pathdependencies, infrastructure, technologies, institutions and behaviours that are embedded in and intertwined with the carbon economy. State revenues derive to a large extent from fossil fuels and previous reforms to support the growth of renewables have been hampered by the fact that the state is both responsible for shaping energy policy and is also the largest stakeholder in Malaysia’s highly centralised fossil-based energy system. Structural changes in both the energy system and decision-making processes are needed to support a timely transition to a sustainable, low-carbon economy. Post-pandemic recovery packages and policy changes can lend critical momentum to this process if they are properly targeted. In this policy brief we identify three key opportunities for action to advance the Malaysian energy transition: Recommendation 1: Broaden the range of actors in the electricity sector Efforts to liberalise Malaysia’s highly concentrated electricity sector, increase competition, and improve market efficiency should be strengthened. Existing reform plans should be extended to the areas of transmission and distribution. Recommendation 2: Involve stakeholders in policy design processes The government should facilitate the participation of stakeholders in all stages of the policy process by formalising participation processes and establishing permanent, independent bodies to vet government decisions as well as regular forums for stakeholder dialogue. The decentralisation of decision processes should be promoted. Recommendation 3: Prioritise green growth in post-pandemic recovery programmes Recovery programmes should prioritise investment in sustainable energy infrastructure, clean technology industries, capacity-building, and research and development. Targeted social investment is needed to cushion the social impacts of decarbonisation and harness co-benefits.

Beschreibung: Als Teil der kollaborativen Aktionsforschung des Deutsch-Französischen Zukunftswerkes beleuchtet diese Studie die aktuellen Entwicklungen der Universitätsstadt Marburg in ihren Bestrebungen, bis 2030 klimaneutral zu werden. Die Analyse skizziert die Chancen und Herausforderungen lokaler Klimapolitik. Sie zeigt auf, wie trotz einer hohen Motivation seitens der lokalen politischen Führung und der Zivilgesellschaft, die Klimaneutralität zu erreichen, strukturelle Hemmnisse – wie zum Beispiel eine versäulte Verwaltung, Mangel an Kapazitäten und Ressourcen für die Messung des Fortschritts und für strukturierte Beteiligungs- und Kollaborationsmöglichkeiten – die Umsetzung des lokalen Klima-Aktionsplans ausbremsen können. Anhand der Daten über einen Beobachtungszeitraum von einem Jahr erläutert die Analyse ebenso, wie transformative Forschungsansätze, in Form von regelmäßigen Reflektionen mit Akteur:innen vor Ort, lokale Bestrebungen der Klimapolitik unterstützen und vorantreiben können.

Beschreibung: This paper reflects on how, and under what conditions local transformative change towards climate neutrality can flourish, based on the case of the German city of Marburg, which has committed to become a climate neutral city by 2030. The research findings are drawn from the work of the Franco-German Forum for the Future established in 2020. The Forum seeks to accelerate social and ecological transformation through collaborative action research with pioneering municipalities in France and Germany, through the fostering of dialogue among these initiatives and through the development of political recommendations for the respective national governments. We show how despite a strong political will in Marburg among both political leadership and civil society to act decisively for the achievement of climate neutrality, institutional constraints, such as a lack of flexibility within the local administration, shortage of capacity and resources for the monitoring of progress and the absence of institutionalised mechanisms for citizen participation and collaboration can hamper progress towards achieving the ambitious goals.

Beschreibung: W ostatnich latach coraz większą uwagę zyskują wyzwania stojące przed europejskimi regionami związane ze zmianami strukturalnymi w kierunku zrównoważonego rozwoju. Łużyce, leżące na granicy Niemiec i Polski, doświadczają znacznej presji związanej z transformacją. Krajowe i europejskie programy finansowania, m.in. w ramach Europejskiego Zielonego Ładu, mają na celu łagodzenie skutków odchodzenia od wydobycia i konsumpcji węgla. Niedawno przyjęty unijny Mechanizm Sprawiedliwej Transformacji ma za zadanie wspieranie zrównoważonych zmian strukturalnych poprzez pomoc pracownikom i przyczynianie się do dywersyfikacji gospodarki w najbardziej dotkniętych obszarach. Niniejszy Policy Brief przedstawia trzy rekomendacje związane z wykorzystaniem funduszy UE w polsko-niemieckim obszarze granicznym w celu wspierania sprawiedliwej transformacji. Po pierwsze, fundusze udostępnione w ramach Mechanizmu powinny być wykorzystywane w porozumieniu z regionalnymi interesariuszami w Łużycach w celu uzupełnienia krajowych środków wsparcia. Dalsze programy finansowania ukierunkowane na różne obszary polityki publicznej powinny być wykorzystane w celu wzmocnienia spójności w całym regionie. W tym kontekście szczególnie interesujące są programy zarządzane centralnie przez Komisję Europejską (tzn. nie podlegające zarządzaniu dzielonemu z rządami krajowymi). Ściślejsza współpraca polityczna i gospodarcza, w połączeniu z głębszą wymianą doświadczeń, może przyspieszyć integrację regionalną i ukierunkować procesy przekształceń strukturalnych na osiągnięcie trwałych rezultatów. Użycie tych programów w obszarze granicznym obarczone jest jednak praktycznymi przeszkodami, które należy pokonać. Ponadto powyżej wymienione działania powinny być realizowane zgodne z celami zrównoważonego rozwoju (SDGs), przyczyniać się do osiągnięcia celu, jakim jest neutralność klimatyczna, a także do złagodzenia społecznych skutków transformacji strukturalnej na wszystkich poziomach.

Beschreibung: The STRONG High Seas project has published a Glossary of Ocean Governance Terms to provide decision-makers and other stakeholders, including the private sector, scientific communities, civil society, and traditional communities, with a reference lexicon on ocean governance related terms to facilitate understanding when engaging in negotiations and implementation of international and national policies and regulations. As in most areas of knowledge or activity, the field of ocean governance is associated with specialized terminology, or jargon. The use of specific terms is essential for clear communication, particularly among peers, but also to a wider audience. However, as one area becomes more specialized and consequently the use of jargons increases, the challenge for comprehensible communication also grows. A shared understanding of terms by stakeholders engaging in policy instruments is particularly critical. Texts of policy instruments and of decisions (or similar documents, such as Resolutions or measures) under these instruments are, in some cases, legally-binding, which makes States Parties generally abide by them. The same word could have different meaning to different audiences and at different times. Having a common understanding of a term will, therefore, ease communication and, ultimately, help decision-makers achieve agreement in a political context.

Beschreibung: In dieser qualitativen Analyse dreier kommunaler Planungsprozesse wird das in Norderstedt entstehende Quartier „Grüne Heyde“ mit dem etwa gleichzeitig entstehenden Hamburger Stadtteil „Oberbillwerder“ sowie der lang zurückliegenden Planung des „Rotbäumlesfeldes“ in Ludwigsburg verglichen. In allen drei Fällen wurden besondere Ansprüche an die Nachhaltigkeit der Planungen gestellt und jeweils in unterschiedlichem Grade realisiert und durchgehalten. Die Studie arbeitet heraus, dass insbesondere der Zugriff auf verwaltungsexterne Kompetenzen, die explizite Heraushebung der Vorhaben als „Modelle“, der Bezug auf gesamtstädtisch-strategische Ziele sowie der Mut, beim Projektmanagement strukturell zu experimentieren, in einigen der Fälle zu einem ‚Mehr‘ an Nachhaltigkeit beitrugen bzw. dass diese Faktoren dort, wo sie fehlten, zu Risiken in der Planung führten. Eine strategisch durchdachte Bodenpolitik bildet einen weiteren Einflussfaktor, der sich aufgrund der Fallstudien solide bejahen lässt, während Öffentlichkeitskommunikation und -beteiligung in ihrer Auswirkung auf die städtebaulichen Qualitäten schwerer zu beurteilen sind. Der Studie separat zugeordnet ist ein Einleger mit Handlungsempfehlungen an kommunale Verwaltungen.

Beschreibung: In this qualitative analysis of three municipal planning processes, the housing project “Grüne Heyde” in Norderstedt is compared with projects in Hamburg (“Oberbillwerder”) and Ludwigsburg (“Rotbäumlesfeld”). The former two are still being developed whereas the third was planned quite some time ago. In all three cases, special demands were made for sustainable planning which were carried out and maintained to different degrees. The study shows that especially making use of competencies external to public administration, the fact that the projects are explicitly called “models”, the reference to strategic goals for the city as a whole, and the courage to experiment structurally in project management contributed to “more” sustainability in some of the cases. On the other hand, these factors led to risks in planning where they were lacking. A strategically though-out land policy is another influential factor that can be solidly affirmed on the basis of the case studies; however, public communication and participation are more difficult to assess in terms of their impact on urban development qualities. The study is accompanied by an insert with recommendations for action for municipal administrations.

Beschreibung: Cette analyse qualitative de trois processus de planification communaux compare le quartier “Grüne Heyde” en cours de réalisation à Norderstedt avec le quartier “Oberbillwerder” à Hambourg, qui a vu le jour à peu près au même moment, ainsi que la planification du “Rotbäumlesfeld” à Ludwigsburg, qui remonte à plus longtemps. Dans les trois cas, des exigences particulières ont été posées à la durabilité des planifications, qui ont été réalisées et maintenues à des degrés divers. L'étude montre que le recours à des compétences externes à l'administration, la mise en avant explicite des projets en tant que “modèles”, la référence à des objectifs stratégiques pour l'ensemble de la ville ainsi que le courage d'expérimenter des structures de gestion de projet ont contribué dans certains cas à un “plus” en matière de durabilité ou que ces facteurs ont entraîné des risques dans la planification lorsqu'ils faisaient défaut. Une politique foncière stratégiquement réfléchie constitue un autre facteur d’une influence positive sur la durabilité de ces études de cas, tandis que la communication et la participation du public sont plus difficiles à évaluer dans leur impact sur les qualités urbanistiques. L'étude est accompagnée d'un encart contenant des recommandations d'action pour les administrations communales.

Beschreibung: The deployment of solar photovoltaic (PV) technology is accelerating across the globe, as prices continue to fall and countries begin their transition from fossil to renewable energy. Public auctions have become the dominant policy tool for solar PV deployment: 106 countries held renewable energy auctions (dominated by solar) by the end of 2018 (IRENA a, 2019). One third of the 55 countries that held renewable auctions in 2017 – 2018 did so for the first time (ibid.). Little solar-specific experience and capacity in newly adopting countries can result in technical failures and lower solar plant performance (IRENA 2017). For instance, it was reported that 30 percent of nearly 100 analysed projects in different countries indicate severe defects that impact performance (TÜV Rheinland 2015). This makes investment in solar plants in newcomer countries risky, hindering the development of the solar sector and undermining political targets of solar energy deployment in these countries. In this context, international organisations have suggested that policymakers in adopting countries include international quality standards1 as technical requirements in the design of public auctions. This policy brief outlines the potential benefits and challenges of doing so, highlighting the crucial role of the Quality Infrastructure (QI) system in newcomer countries. Key lessons learnt are synthesised from international experiences with technical requirements in solar PV auctions. On this basis, entry points are identified for the development of strategies for their introduction in newly adopting countries. The two key things policymakers should consider are the adoption of appropriate standards based on the specific country context and the implementation of real-time data monitoring.

Beschreibung: This report was prepared as part of the STRONG High Seas project, based on a series of stakeholder surveys and experience gathered through various workshops held in the Southeast Atlantic region, as well as on literature surveys and expert opinion. The report was reviewed by multiple experts to validate findings and ensure robust content. This report is part of a series of reports covering issues of ocean governance with a focus on the ABNJ of the Southeast Pacific and the Southeast Atlantic regions and builds on previous reports published by the STRONG High Seas project. Further project reports cover the legal and institutional framework applicable to ABNJ, the ecological state and the socioeconomic importance of ABNJ in the project regions, options for management and conservation measures for conservation of marine biodiversity in ABNJ, and considerations for integrated ocean management. These reports are available through the STRONG High Seas project website.

Beschreibung: Ce document est un guide pragmatique à destination de ceux qui souhaitent coopérer avec les organisations régionales de gestion des pêches (ORGP). Il explique comment mettre en œuvre des mesures de conservation dans une ORGP, en adoptant des décisions juridiquement contraignantes. Il s’agit d’une synthèse d’expériences personnelles, composées de réussites et d’échecs, et d’un aperçu de certains des aspects les plus obscurs des ORGP. L’objectif de ce document est celui du projet STRONG High Seas – explorer le régime de gouvernance fracture des océans, et plus précisément pour ce travail, formuler des conseils pour soutenir la mise en œuvre de la conservation spatiale en haute mer. Ce travail s’inscrit donc dans le contexte de la mise en place de mesures de conservation spatiale, mais s’inspire d’exemples tirés d’autres efforts de préservation de la biodiversité et propose des orientations pour la mise en place de mesures contraignantes pour tout type de sujet, dans n’importe quelle ORGP.

Beschreibung: In einem Bürgerrat erarbeitet eine heterogen zusammengesetzte und zufällig ausgewählte Gruppe von Bürgerinnen und Bürgern Empfehlungen zu einer bestimmten Fragestellung. Bürgerräte werden meist von politischen Entscheidungsträgerinnen und -trägern eingesetzt und stellen eine Ergänzung zu repräsentativen Entscheidungen dar. Im Folgenden wird dargestellt, wie Bürgerräte ablaufen, warum sie zum Einsatz kommen und was gelungene Bürgerräte ausmacht.

Beschreibung: La gestion intégrée des océans (GIO) est une approche adaptative de la gestion des activités humaines dans l'océan, qui est ancrée dans l'approche écosystémique. Elle nécessite la prise en compte de toutes les dimensions de l'espace océanique – sphères physique, océanographique, climatique, biologique, sociale, économique – et inclut la dynamique spatiale et temporelle du système. Elle vise à créer un cadre pour une économie océanique durable. Pour atteindre cet objectif ambitieux, les processus de gestion doivent être intégrés dans la gouvernance, les parties prenantes, les connaissances, la dynamique du système et être transfrontaliers, ce qui constituera les "piliers" d'une intégration efficace. Les principales caractéristiques de l'approche intégrée proposée pour la gestion des océans exigent une collaboration accrue, le partage des connaissances, la transparence, la coordination et la communication. Les points de vue et les valeurs des communautés, ainsi que les connaissances scientifiques, traditionnelles et locales, jouent un rôle clé dans la definition de la conception et de l'opérationnalisation des piliers susmentionnés. L'approche de la GIO n'a pas encore été appliquée aux zones situées au-delà des limites de la juridiction nationale, mais elle est couramment appliquée aux eaux côtières. La GIO sera de plus en plus importante dans les ZAJN pour relever les défis croissants de la conservation et de l'utilisation durable de la biodiversité marine. Ce rapport vise donc à donner un aperçu de l'application de la GIO dans le contexte de la conservation et de l'utilisation durable de la biodiversité marine dans les ZAJN, en particulier dans les régions de l'Atlantique du Sud-Est et du Pacifique du Sud-Est. Il vise en particulier à promouvoir l'application de la GIO pour les ZAJN à travers les secteurs et les dimensions écologiques en envisageant l'application de conditions favorables pour parvenir à une coopération et une collaboration entre les différents acteurs travaillant dans les ZAJN ou les affectant. Ce rapport résume les défis actuels auxquels est confrontée la gestion des ZAJN, identifie les opportunités de mise en œuvre de la GIO à travers les frontières et fournit des recommandations pour aller de l'avant sur cette priorité urgente, guidée par les objectifs de développement durable. La question de la GIO dans les ZAJN est particulièrement pertinente à l'heure actuelle, car les Etats négocient actuellement un nouvel instrument juridiquement contraignant pour la protection et l'utilisation durable de la biodiversité marine dans les ZAJN (appelé dans le présent rapport l'Accord BZAJN). Les États ont donc la possibilité d'intégrer des dispositions qui permettront à la GIO d'être pleinement opérationnelle dans le cadre de l'Accord BZAJN dès son adoption et sa ratification. Ce rapport couvre les concepts de la GIO, ses piliers, l'importance de la GIO pour la conservation et l'utilisation durable de la biodiversité marine dans les ZAJN et les opportunités de renforcement de la GIO pour la conservation des ZAJN dans les deux régions focales du projet STRONG High Seas: l'Atlantique du Sud-Est et le Pacifique du Sud-Est. Après avoir analysé les opportunités dans ces deux régions, ce rapport met en évidence certaines voies claires par lesquelles cette approche intégrée peut soutenir de manière significative la conservation de la biodiversité dans les ZAJN. Les recommandations sélectionnées dans ce rapport sont incluses ci-dessous. Pour un ensemble plus complet d'actions et de décisions possibles qui pourraient être adoptées par une série d'acteurs pour améliorer la GIO, voir Table 2 au chapitre 3.

Beschreibung: This report contributes to the modelling work in SENTINEL and beyond in three main ways. First, we provide three social storylines that are closely linked to different governance logics and build on observed social and political drivers and barriers in the European energy transition. This is different than most other storylines used for modelling, because ours are based on governance patterns and normative assumptions of a “good future”, and not on the more commonly used geopolitical or techno-economic storyline assumptions. Second, we provide quantitative, empirical data for several important social/political parameters that can be used together with the storylines or as separate building blocks to answer specific research questions with energy models. Third, to test the usefulness of QTDIAN, we have soft-linked QTDIAN with the energy demand models DESSTINEE, HEB and DREEM, the energy system design model Euro-Calliope, and indirectly with the economic model WEGDYN. Based on feedback from the modelling exercises, we have revised QTDIAN and publish now this updated report 2.0 to improve its usefulness for a more realistic analysis of potential future energy systems.

Beschreibung: Die Arktis erwärmt sich substanziell schneller als der globale Durchschnitt. Der rasche Temperatur-anstieg verändert die Arktis bereits tiefgreifend - und wird dies auch weiterhin tun - mit noch unbekannten Folgen für die Region und die ganze Welt. Gleichzeitig mit dem Rückgang des Meereises und der sich verändernden Verteilung der lebenden Meeresressourcen hat eine Zunahme des wirtschaftlichen Interesses an der Region zu Bedenken hinsichtlich der Nachhaltigkeit der wirtschaftlichen Aktivitäten in der Arktis geführt. Um Wege zu finden, wie der Schutz und die nachhaltige Nutzung der arktischen Meeresumwelt gewährleistet werden können, ist ein umfassendes Verständnis der Meeresumwelt, der sie beeinflussen-den Belastungen und der relevanten Regulierungen und Managementmaßnahmen erforderlich. DasEcologic Institut und das Institute for Advanced Sustainability Studies haben sich zum Ziel gesetzt, durch eine Reihe von Berichten zum Meeresschutz in der Arktis einen Überblick über die relevantenInformationen zu geben. Die Berichte konzentrieren sich auf die fünf arktischen Anrainerstaaten: Ka-nada, Dänemark (durch Grönland), Norwegen, die Russische Föderation und die Vereinigten Staaten.Darüber hinaus gibt ein regionaler Bericht einen umfassenden Überblick und fasst die einschlägigen internationalen und regionalen Vorschriften zusammen. Der vorliegende Bericht behandelt die für den Meeresschutz in der norwegischen Arktis relevantenInformationen. Der Bericht deckt vier Hauptthemen ab: Er beginnt mit der Beschreibung der wichtigsten Merkmale der Meeresumwelt der norwegischen Arktis. Anschließend werden wesentlichenBelastungen untersucht, die sich auf die marine Biodiversität in der Region auswirken, gefolgt von einer Untersuchung der soziokulturellen und wirtschaftlichen Rolle sowie der Umweltauswirkungen der wichtigsten meeresbezogenen menschlichen Aktivitäten in der norwegischen Arktis. Der letzteTeil des Berichts gibt einen Überblick über die relevanten nationalen Institutionen sowie über Regulierungen, Vorschriften und Instrumente, die zum Schutz der norwegischen arktischen Meeresbiodiversität und zur Gewährleistung ihrer nachhaltigen Nutzung eingesetzt werden oder eingesetzt wer-den könnten. Hinweis: Die in diesem Bericht präsentierten Informationen wurden hauptsächlich während der weltweiten Covid-19-Pandemie und vor dem russischen Einmarsch in die Ukraine im Jahr 2022 zusammengetragen. Die (weiteren) politischen und wirtschaftlichen Auswirkungen dieser Ereignisse und dies ich daraus ergebenden Veränderungen in der Arktis-Governance sind zum jetzigen Zeitpunkt nichtabsehbar, und es ist zu erwarten, dass sich einige der in diesem Bericht dargestellten Entwicklungen und Trends erheblich ändern werden. Die Kernbotschaften des Berichts finden sich unter der folgenden englischen Zusammenfassung.

Beschreibung: The Arctic is warming three times faster than the global average. These rapidly increasing temperatures are already profoundly changing the Arctic, and will continue to do so, with yet unknown con-sequences for the region as well as worldwide. The diminishing sea ice extent and the changing distribution of marine living resources have led to an increase in economic interest in the region as well as concerns about the sustainability of economic activities in the Arctic. In order to identify ways in which conservation and sustainable use of the Arctic marine environment can be ensured, a broad understanding of the marine environment, the pressures affecting it, and the relevant regulations is needed. Ecologic Institute and the Institute for Advanced Sustainability Studies aim to provide an overview of relevant information through a series of reports on marine conservation in the Arctic. The reports focus on the five Arctic coastal states: Canada, Denmark (by virtue of Green-land), Norway, the Russian Federation, and the United States. In addition, a regional report is providing a broader overview and summarises relevant international and regional regulations. This current report presents an overview of information relevant to marine conservation in the Norwegian Arctic. The report covers four main issues: it starts with the description of the key characteristics of the Norwegian Arctic marine environment. Then it examines significant pressures impacting marine biodiversity in the region, followed by exploring the socio-cultural and economic role as well as the environmental impact of the main sea-based human activities in the Norwegian Arctic. The last part of the report describes the Norwegian ocean governance system and provides an overview of relevant national institutions as well as rules, regulations and tools which are, or could be, employed to protect Norwegian Arctic marine biodiversity and ensure its sustainable use. NB: The information presented in this report was mainly collated during the global Covid-19 pandemic and prior to the 2022 Russian invasion of Ukraine. The (further) political and economic impacts of these events and resulting changes in Arctic governance cannot be foreseen at this point in time and it can be expected that some of the developments and trends presented in this report may change substantially.

Beschreibung: Efforts to collaboratively manage the risk of flooding are ultimately based on individuals learning about risks, the decision process, and the effectiveness of decisions made in prior situations. This article argues that much can be learned about a governance setting by explicitly evaluating the relationships through which influential individuals and their immediate contacts receive and send information to one another. We define these individuals as “brokers,” and the networks that emerge from their interactions as “learning spaces.” The aim of this article is to develop strategies to identify and evaluate the properties of a broker's learning space that are indicative of a collaborative flood risk management arrangement. The first part of this article introduces a set of indicators, and presents strategies to employ this list so as to systematically identify brokers, and compare their learning spaces. The second part outlines the lessons from an evaluation that explored cases in two distinct flood risk management settings in Germany. The results show differences in the observed brokers' learning spaces. The contacts and interactions of the broker in Baden‐Württemberg imply a collaborative setting. In contrast, learning space of the broker in North Rhine‐Westphalia lacks the same level of diversity and polycentricity.

Beschreibung: Most common machine learning (ML) algorithms usually work well on balanced training sets, that is, datasets in which all classes are approximately represented equally. Otherwise, the accuracy estimates may be unreliable and classes with only a few values are often misclassified or neglected. This is known as a class imbalance problem in machine learning and datasets that do not meet this criterion are referred to as imbalanced data. Most datasets of soil classes are, therefore, imbalanced data. One of our main objectives is to compare eight resampling strategies that have been developed to counteract the imbalanced data problem. We compared the performance of five of the most common ML algorithms with the resampling approaches. The highest increase in prediction accuracy was achieved with SMOTE (the synthetic minority oversampling technique). In comparison to the baseline prediction on the original dataset, we achieved an increase of about 10, 20 and 10% in the overall accuracy, kappa index and F‐score, respectively. Regarding the ML approaches, random forest (RF) showed the best performance with an overall accuracy, kappa index and F‐score of 66, 60 and 57%, respectively. Moreover, the combination of RF and SMOTE improved the accuracy of the individual soil classes, compared to RF trained on the original dataset and allowed better prediction of soil classes with a low number of samples in the corresponding soil profile database, in our case for Chernozems. Our results show that balancing existing soil legacy data using synthetic sampling strategies can significantly improve the prediction accuracy in digital soil mapping (DSM). Highlights Spatial distribution of soil classes in Iran can be predicted using machine learning (ML) algorithms. The synthetic minority oversampling technique overcomes the drawback of imbalanced and highly biased soil legacy data. When combining a random forest model with synthetic sampling strategies the prediction accuracy of the soil model improves significantly. The resulting new soil map of Iran has a much higher spatial resolution compared to existing maps and displays new soil classes that have not yet been mapped in Iran.

Beschreibung: The application of biochar to agricultural soils to increase nutrient availability, crop production and carbon sequestration has gained increasing interest but data from field experiments on temperate, marginal soils are still under‐represented. In the current study, biochar, produced from organic residues (digestates) from a biogas plant, was applied with and without digestates at low (3.4 t ha−1) and intermediate (17.1 t ha−1) rates to two acidic and sandy soils in northern Germany that are used for corn (Zea mays L.) production. Soil nutrient availability, crop yields, microbial biomass and carbon dioxide (CO2) emissions from heterotrophic respiration were measured over two consecutive years. The effects of biochar application depended on the intrinsic properties of the two tested soils and the biochar application rates. Although the soils at the fallow site, with initially low nutrient concentrations, showed a significant increase in pH, soil nutrients and crop yield after low biochar application rates, a similar response was found at the cornfield site only after application of substantially larger amounts of biochar. The effect of a single dose of biochar at the beginning of the experiment diminished over time but was still detectable after 2 years. Whereas plant available nutrient concentrations increased after biochar application, the availability of potentially phytotoxic trace elements (Zn, Pb, Cd, Cr) decreased significantly, and although slight increases in microbial biomass carbon and heterotrophic CO2 fluxes were observed after biochar application, they were mostly not significant. The results indicate that the application of relatively small amounts of biochar could have positive effects on plant available nutrients and crop yields of marginal arable soils and may decrease the need for mineral fertilizers while simultaneously increasing the sequestration of soil organic carbon. Highlights A low rate of biochar increased plant available nutrients and crop yield on marginal soils. Biochar application reduced the availability of potentially harmful trace elements. Heterotrophic respiration showed no clear response to biochar application. Biochar application may reduce fertilizer need and increase carbon sequestration on marginal soils.

Beschreibung: Social inequalities lead to flood resilience inequalities across social groups, a topic that requires improved documentation and understanding. The objective of this paper is to attend to these differences by investigating self‐stated flood recovery across genders in Vietnam as a conceptual replication of earlier results from Germany. This study employs a regression‐based analysis of 1,010 respondents divided between a rural coastal and an urban community in Thua Thien‐Hue province. The results highlight an important set of recovery process‐related variables. The set of relevant variables is similar across genders in terms of inclusion and influence, and includes age, social capital, internal and external support after a flood, perceived severity of previous flood impacts, and the perception of stress‐resilience. However, women were affected more heavily by flooding in terms of longer recovery times, which should be accounted for in risk management. Overall, the studied variables perform similarly in Vietnam and Germany. This study, therefore, conceptually replicates previous results suggesting that women display slightly slower recovery levels as well as that psychological variables influence recovery rates more than adverse flood impacts. This provides an indication of the results' potentially robust nature due to the different socio‐environmental contexts in Germany and Vietnam.

Beschreibung: Nitrogen (N) fertilization is the major contributor to nitrous oxide (N2O) emissions from agricultural soil, especially in post‐harvest seasons. This study was carried out to investigate whether ryegrass serving as cover crop affects soil N2O emissions and denitrifier community size. A microcosm experiment was conducted with soil planted with perennial ryegrass (Lolium perenne L.) and bare soil, each with four levels of N fertilizer (0, 5, 10 and 20 g N m−2; applied as calcium ammonium nitrate). The closed‐chamber approach was used to measure soil N2O fluxes. Real‐time PCR was used to estimate the biomass of bacteria and fungi and the abundance of genes involved in denitrification in soil. The results showed that the presence of ryegrass decreased the nitrate content in soil. Cumulative N2O emissions of soil with grass were lower than in bare soil at 5 and 10 g N m−2. Fertilization levels did not affect the abundance of soil bacteria and fungi. Soil with grass showed greater abundances of bacteria and fungi, as well as microorganisms carrying narG, napA, nirK, nirS and nosZ clade I genes. It is concluded that ryegrass serving as a cover crop holds the potential to mitigate soil N2O emissions in soils with moderate or high NO3− concentrations. This highlights the importance of cover crops for the reduction of N2O emissions from soil, particularly following N fertilization. Future research should explore the full potential of ryegrass to reduce soil N2O emissions under field conditions as well as in different soils. Highlights This study was to investigate whether ryegrass serving as cover crop affects soil N2O emissions and denitrifier community size; Plant reduced soil N substrates on one side, but their root exudates stimulated denitrification on the other side; N2O emissions were lower in soil with grass than bare soil at medium fertilizer levels, and growing grass stimulated the proliferation of almost all the denitrifying bacteria except nosZ clade II; Ryegrass serving as a cover crop holds the potential to mitigate soil N2O emissions.

Beschreibung: High‐performance numerical codes are an indispensable tool for hydrogeologists when modeling subsurface flow and transport systems. But as they are written in compiled languages, like C/C++ or Fortran, established software packages are rarely user‐friendly, limiting a wider adoption of such tools. OpenGeoSys (OGS), an open‐source, finite‐element solver for thermo‐hydro‐mechanical–chemical processes in porous and fractured media, is no exception. Graphical user interfaces may increase usability, but do so at a dramatic reduction of flexibility and are difficult or impossible to integrate into a larger workflow. Python offers an optimal trade‐off between these goals by providing a highly flexible, yet comparatively user‐friendly environment for software applications. Hence, we introduce ogs5py, a Python‐API for the OpenGeoSys 5 scientific modeling package. It provides a fully Python‐based representation of an OGS project, a large array of convenience functions for users to interact with OGS and connects OGS to the scientific and computational environment of Python.

Beschreibung: Transport processes that lead to exchange of mass between surface water and groundwater play a significant role for the ecological functioning of aquatic systems, for hydrological processes and for biogeochemical transformations. In this study, we present a novel integral modeling approach for flow and transport at the sediment–water interface. The model allows us to simultaneously simulate turbulent surface and subsurface flow and transport with the same conceptual approach. For this purpose, a conservative transport equation was implemented to an existing approach that uses an extended version of the Navier–Stokes equations. Based on previous flume studies which investigated the spreading of a dye tracer under neutral, losing and gaining flow conditions the new solver is validated. Tracer distributions of the experiments are in close agreement with the simulations. The simulated flow paths are significantly affected by in‐ and outflowing groundwater flow. The highest velocities within the sediment are found for losing condition, which leads to shorter residence times compared to neutral and gaining conditions. The largest extent of the hyporheic exchange flow is observed under neutral condition. The new solver can be used for further examinations of cases that are not suitable for the conventional coupled models, for example, if Reynolds numbers are larger than 10. Moreover, results gained with the integral solver provide high‐resolution information on pressure and velocity distributions at the rippled streambed, which can be used to improve flow predictions. This includes the extent of hyporheic exchange under varying ambient groundwater flow conditions.

Beschreibung: Sustainable arable cropping relies on repeated liming. Yet, the associated increase in soil pH can reduce the availability of iron (Fe) to plants. We hypothesized that repeated liming, but not pedogenic processes such as lessivage (i.e., translocation of clay particles), alters the Fe cycle in Luvisol soil, thereby affecting Fe isotope composition in soils and crops. Hence, we analysed Fe concentrations and isotope compositions in soil profiles and winter rye from the long‐term agricultural experimental site in Berlin‐Dahlem, Germany, where a controlled liming trial with three field replicates per treatment has been conducted on Albic Luvisols since 1923. Heterogeneity in subsoil was observed at this site for Fe concentration but not for Fe isotope composition. Lessivage had not affected Fe isotope composition in the soil profiles. The results also showed that almost 100 years of liming lowered the concentration of the HCl‐extractable Fe that was potentially available for plant uptake in the surface soil (0–15 cm) from 1.03 (standard error (SE) 0.03) to 0.94 (SE 0.01) g kg−1. This HCl‐extractable Fe pool contained isotopically lighter Fe (δ56Fe = −0.05 to −0.29‰) than the bulk soil (δ56Fe = −0.08 to 0.08‰). However, its Fe isotope composition was not altered by the long‐term lime application. Liming resulted in relatively lower Fe concentrations in the roots of winter rye. In addition, liming led to a heavier Fe isotope composition of the whole plants compared with those grown in the non‐limed plots (δ56FeWholePlant_ + Lime = −0.12‰, SE 0.03 vs. δ56FeWholePlant_‐Lime = −0.21‰, SE 0.01). This suggests that the elevated soil pH (increased by one unit due to liming) promoted the Fe uptake strategy through complexation of Fe(III) from the rhizosphere, which favoured heavier Fe isotopes. Overall, the present study showed that liming and a related increase in pH did not affect the Fe isotope compositions of the soil, but may influence the Fe isotope composition of plants grown in the soil if they alter their Fe uptake strategy upon the change of Fe availability. Highlights Fe concentrations and stocks, but not Fe isotope compositions, were more heterogeneous in subsoil than in topsoil. Translocation of clay minerals did not result in Fe isotope fractionation in the soil profile of a Luvisol. Liming decreased Fe availability in topsoil, but did not affect its δ56Fe values. Uptake of heavier Fe isotopes by graminaceous crops was more pronounced at elevated pH.

Beschreibung: We present a workflow to estimate geostatistical aquifer parameters from pumping test data using the Python package welltestpy. The procedure of pumping test analysis is exemplified for two data sets from the Horkheimer Insel site and from the Lauswiesen site, Germany. The analysis is based on a semi‐analytical drawdown solution from the upscaling approach Radial Coarse Graining, which enables to infer log‐transmissivity variance and horizontal correlation length, beside mean transmissivity, and storativity, from pumping test data. We estimate these parameters of aquifer heterogeneity from type‐curve analysis and determine their sensitivity. This procedure, implemented in welltestpy, is a template for analyzing any pumping test. It goes beyond the possibilities of standard methods, for example, based on Theis' equation, which are limited to mean transmissivity and storativity. A sensitivity study showed the impact of observation well positions on the parameter estimation quality. The insights of this study help to optimize future test setups for geostatistical aquifer analysis and provides guidance for investigating pumping tests with regard to aquifer statistics using the open‐source software package welltestpy.

Beschreibung: In designed experiments, different sources of variability and an adequate scale of measurement need to be considered, but not all approaches in common usage are equally valid. In order to elucidate the importance of sources of variability and choice of scale, we conducted an experiment where the effects of biochar and slurry applications on soil properties related to soil fertility were studied for different designs: (a) for a field‐scale sampling design with either a model soil (without natural variability) as an internal control or with composited soils, (b) for a design with a focus on amendment variabilities, and (c) for three individual field‐scale designs with true field replication and a combined analysis representative of the population of loess‐derived soils. Three silty loam sites in Germany were sampled and the soil macroaggregates were crushed. For each design, six treatments (0, 0.15 and 0.30 g slurry‐N kg−1 with and without 30 g biochar kg−1) were applied before incubating the units under constant soil moisture conditions for 78 days. CO2 fluxes were monitored and soils were analysed for macroaggregate yields and associated organic carbon (C). Mixed‐effects models were used to describe the effects. For all soil properties, results for the loess sites differed with respect to significant contributions of fixed effects for at least one site, suggesting the need for a general inclusion of different sites. Analysis using a multilevel model allowed generalizations for loess soils to be made and showed that site:slurry:biochar and site:slurry interactions were not negligible for macroaggregate yields. The use of a model soil as an internal control enabled observation of variabilities other than those related to soils or amendments. Experiments incorporating natural variability in soils or amendments resulted in partially different outcomes, indicating the need to include all important sources of variability. Highlights Effects of biochar and slurry applications were studied for different designs and mixed‐effects models were used to describe the effects. Including an internal control allowed observation of, e.g., methodological and analytical variabilities. The results suggested the need for a general inclusion of different sites. Analysis using a multilevel model allowed generalizations for loess soils. The results indicated the need to include all important sources of variability.

Beschreibung: Temperate forest soils are often considered as an important sink for atmospheric carbon (C), thereby buffering anthropogenic CO2 emissions. However, the effect of tree species composition on the magnitude of this sink is unclear. We resampled a tree species common garden experiment (six sites) a decade after initial sampling to evaluate whether forest floor (FF) and topsoil organic carbon (Corg) and total nitrogen (Nt) stocks changed in dependence of tree species (Norway spruce—Picea abies L., European beech—Fagus sylvatica L., pedunculate oak—Quercus robur L., sycamore maple—Acer pseudoplatanus L., European ash—Fraxinus excelsior L. and small‐leaved lime—Tilia cordata L.). Two groups of species were identified in terms of Corg and Nt distribution: (1) Spruce with high Corg and Nt stocks in the FF developed as a mor humus layer which tended to have smaller Corg and Nt stocks and a wider Corg:Nt ratio in the mineral topsoil, and (2) the broadleaved species, of which ash and maple distinguished most clearly from spruce by very low Corg and Nt stocks in the FF developed as mull humus layer, had greater Corg and Nt stocks, and narrow Corg:Nt ratios in the mineral topsoil. Over 11 years, FF Corg and Nt stocks increased most under spruce, while small decreases in bulk mineral soil (esp. in 0–15 cm and 0–30 cm depth) Corg and Nt stocks dominated irrespective of species. Observed decadal changes were associated with site‐related and tree species‐mediated soil properties in a way that hinted towards short‐term accumulation and mineralisation dynamics of easily available organic substances. We found no indication for Corg stabilisation. However, results indicated increasing Nt stabilisation with increasing biomass of burrowing earthworms, which were highest under ash, lime and maple and lowest under spruce. Highlights We studied if tree species differences in topsoil Corg and Nt stocks substantiate after a decade. The study is unique in its repeated soil sampling in a multisite common garden experiment. Forest floors increased under spruce, but topsoil stocks decreased irrespective of species. Changes were of short‐term nature. Nitrogen was most stable under arbuscular mycorrhizal species.

Beschreibung: Coping with the growing impacts of flooding in EU countries, a paradigm shift in flood management can be observed, moving from safety‐based towards risk‐based approaches and holistic perspectives. Flood resilience is a common denominator of most of the approaches. In this article, we present the ‘Flood Resilience Rose’ (FRR), a management tool to promote harmonised action towards flood resilience in European regions and beyond. The FRR is a result of a two‐step process. First, based on scientific concepts as well as analysis of relevant policy documents, we identified three ‘levels of operation’. The first level refers to the EU Floods Directive and an extended multi‐layer safety approach, comprising the four different layers of protection, prevention, preparedness and recovery, and related measures to be taken. This level is not independent but depends both on the institutional (second level) and the wider (third level) context. Second, we used surveys, semi‐structured interviews and group discussions during workshops with experts from Belgium, Denmark, Germany, the Netherlands and the United Kingdom to validate the definitions and the FRR's practical relevance. The presented FRR is thus the result of rigorous theoretical and practical consideration and provides a tool capable to strengthen flood risk management practice.

Beschreibung: In recent years, German cities were heavily impacted by pluvial flooding and related damage is projected to increase due to climate change and urbanisation. It is important to ask how to improve urban pluvial flood risk management. To understand the current state of property level adaptation, a survey was conducted in four municipalities that had recently been impacted by pluvial flooding. A hybrid framework based on the Protection Motivation Theory (PMT) and the Protection Action Decision Model (PADM) was used to investigate drivers of adaptive behaviour through both descriptive and regression analyses. Descriptive statistics revealed that participants tended to instal more low‐ and medium‐cost measures than high‐cost measures. Regression analyses showed that coping appraisal increased protection motivation, but that the adaptive behaviour also depends on framing factors, particularly homeownership. We further found that, while threat appraisal solely affects protection motivation and responsibility appraisal affects solely maladaptive thinking, coping appraisal affects both. Our results indicate that PMT is a solid starting point to study adaptive behaviours in the context of pluvial flooding, but we need to go beyond that by, for instance, considering factors of the PADM, such as responsibility, ownership, or respondent age, to fully understand this complex decision‐making process.

Beschreibung: The female flowers (“cones”) of the hop plant (Humulus L.) produce compounds that contribute to the flavor and other properties of beer. Hop leaves and cones produce many of the same compounds, which also confer agronomic traits such as insect and disease resistance. Targeted and untargeted ultraperformance liquid chromatography-quadrupole time-of-flight–mass spectrometry with Waters MSE technology (UPLC-QTof-MSE) metabolomics were used to compare leaf phytochemical compositions of greenhouse-grown southwestern American wild Humulus neomexicanus (A. Nelson and Cockerell) Rydb. against a group of commercial hop cultivars consisting of both pure European Humulus lupulus L. and European–North American hybrids. Principal component analysis showed a clear distinction in chemical profiles between the two groups. H. neomexicanus leaves had a significantly higher content of total α acids (p = 4.4 × 10–9), total bitter acids (p = 2.6 × 10–6), cohumulone (p = 1.0 × 10–13), humulone + adhumulone (p = 9.1 × 10–4), and the prenylflavonoids xanthohumol (p = 0.013) and desmethylxanthohumol (p = 0.029) as well as significantly higher densities of glandular trichomes (p = 1.3 × 10–6), the biosynthetic site of those compounds. Most flavonol glycosides measured were also significantly more abundant in H. neomexicanus (p = 1.5 × 10–22 to 0.0027), whereas phenolic acids were consistently, but generally nonsignificantly (p 〉 0.05), more abundant in the cultivars. The higher bitter acid, prenylflavonoid, and flavonol glycoside content of H. neomexicanus leaves may help to confer more favorable insect and disease-resistance properties.

Beschreibung: Iron is an indispensable metabolic cofactor in both pro- and eukaryotes, which engenders a natural competition for the metal between bacterial pathogens and their human or animal hosts. Bacteria secrete siderophores that extract Fe3+ from tissues, fluids, cells, and proteins; the ligand gated porins of the Gram-negative bacterial outer membrane actively acquire the resulting ferric siderophores, as well as other iron-containing molecules like heme. Conversely, eukaryotic hosts combat bacterial iron scavenging by sequestering Fe3+ in binding proteins and ferritin. The variety of iron uptake systems in Gram-negative bacterial pathogens illustrates a range of chemical and biochemical mechanisms that facilitate microbial pathogenesis. This document attempts to summarize and understand these processes, to guide discovery of immunological or chemical interventions that may thwart infectious disease.

Beschreibung: While thousands of environmental metagenomes have been mined for the presence of novel biosynthetic gene clusters, such computational predictions do not provide evidence of their in vivo biosynthetic functionality. Using fluorescent in situ enzyme assay targeting carrier proteins common to polyketide (PKS) and nonribosomal peptide synthetases (NRPS), we applied fluorescence-activated cell sorting to tunicate microbiome to enrich for microbes with active secondary metabolic capabilities. Single-cell genomics uncovered the genetic basis for a wide biosynthetic diversity in the enzyme-active cells and revealed a member of marine Oceanospirillales harboring a novel NRPS gene cluster with high similarity to phylogenetically distant marine and terrestrial bacteria. Interestingly, this synthase belongs to a larger class of siderophore biosynthetic gene clusters commonly associated with pestilence and disease. This demonstrates activity-guided single-cell genomics as a tool to guide novel biosynthetic discovery.

Beschreibung: People living or working in the Arctic are faced with uncertainty regarding future social, political, economic, and environmental change. This uncertainty is due not least to the ongoing transformations caused by climate change. This paper presents results from a project entitled “Yamal 2040: Scenarios for the Russian Arctic”, which employed ‘Strategic Foresight’, a specific co-design and engagement methodology, to support stakeholders of one particular region in the Arctic, the Yamal-Nenets Autonomous Okrug (Yamal region) in Western Siberia, Russia. It was the project’s objective to respond to this situation of general uncertainty, to develop forward-looking scenarios to better understand the risks and opportunities associated with future transformations in the Arctic. The findings presented here may be of interest for stakeholders in other parts of the Arctic and Russia that depend on the exploitation of fossil fuels and/or are facing complex and uncertain situations.

Beschreibung: This report – Study on the socio-economic importance of areas beyond national jurisdiction (ABNJ) in the Southeast Atlantic region – aims to analyse the socio-economic importance of the ABNJ adjacent to the countries within the Abidjan Convention Area in West, Central and Southern Africa. It characterizes the socio-economic interests in ABNJ, underpinned by the ecosystem services concept, and the actual and potential social and economic outcomes (costs and benefits) associated with the conservation and use (exploitation) of marine resources, both in qualitative, and to the extent possible in quantitative terms. In this study, the term “socio-economics” is taken in a broad context to include the social aspects related to human well-being, livelihoods, impacts on communities, equity, socio-political systems, as well as economic ones. The analysis is based on an extensive literature review of scientific publications, articles, analysis of available data, stakeholder knowledge and experience, as well as expert opinion gathered through targeted interviews. It provides a narrative and forward-looking assessment of the key activities. The information presented is intend-ed to support decision-makers, including government officials, the private sector and other stakeholders to make informed decisions about ABNJ and weigh environmental, social and eco-nomic objectives, in the context of a new internationally binding treaty for the conservation and sustainable use of marine biological diversity beyond national jurisdiction, the BBNJ agreement. This report is part of a series of reports covering issues of ocean governance with a focus on the Southeast Atlantic (and Southeast Pacific) published under the STRONG High Seas project – Strengthening Regional Ocean Governance for the High Seas (June 2017 – May 2022).

Beschreibung: Kopenhagen ist eine der Städte mit der besten Fahrradinfrastruktur weltweit. Um zu verstehen, wie die dänische Hauptstadt das erreicht hat, lohnt sich ein Blick in ihre Vergangenheit. Nach Jahrzehnten der autogerechten Stadtplanung, vor der auch Kopenhagen nicht gefeit war, demonstrierten in den späten 1970er und frühen 1980er Jahren Zehntausende für mehr Radwege – mit Erfolg. Welche Rolle haben Diskurse und Erzählungen über das Fahrrad im Dänemark dieser Zeit gespielt, damit aus Kopenhagen die Fahrradstadt werden konnte, die sie heute ist? Und was können wir daraus lernen, um selbst die politische Förderung des Fahrrads als nachhaltiges Verkehrsmittel kommunikativ zu befördern? Diesen Fragen widmet sich das vorliegende Discussion Paper. Es untersucht drei repräsentative Korpora der auflagenstärksten Tageszeitungen Dänemarks aus den Jahren 1977, 1980 und 1983 mithilfe der im Projekt „Narrative der Nachhaltigkeit“ entwickelten „pentadischen“ Narrativanalyse. Das Ziel ist es, erfolgreiche Narrative für die Verkehrswende hin zu einer nachhaltigen urbanen Mobilität zu identifizieren.

Beschreibung: Ce rapport - Étude sur l‘importance socio-économique des zones situées au-delà de la juridiction nationale (ZAJN) dans la région de l‘Atlantique Sud-Est - vise à analyser l‘importance socio-économique des ZAJN adjacentes aux pays de la region de la Convention d‘Abidjan en Afrique occidentale, centrale et australe. Elle caractérise les intérêts socio-économiques dans les ZAJN, étayés par le concept de services écosystémiques, et les résultats sociaux et économiques réels et potentiels (coûts et bénéfices) associés à la conservation et à l‘utilisation (exploitation) des ressources marines, à la fois en termes qualitatifs et, dans la mesure du possible, en termes quantitatifs. Dans cette étude, le terme „socio-économique“ est pris dans un contexte large pour inclure les aspects sociaux liés au bien-être humain, aux moyens de subsistance, aux impacts sur les communautés, à l‘équité, aux systèmes socio-politiques, ainsi que les aspects économiques. L‘analyse se fonde sur une étude approfondie de publications et d‘articles scientifiques, sur l‘analyse des données disponibles, sur les connaissances et l‘expérience des parties prenantes, ainsi que sur l‘opinion d‘experts recueillie lors d‘entretiens ciblés. Elle fournit une évaluation narrative et prospective des activités clés. Les informations présentées ont pour but d‘aider les décideurs, y compris les responsables gouvernementaux, le secteur privé et d‘autres parties prenantes, à prendre des décisions éclairées sur les ZAJN et à peser les objectifs environnementaux, sociaux et économiques, dans le contexte d‘un nouveau traité international contraignant pour la conservation et l‘utilisation durable de la biodiversité marine audelà de la juridiction nationale, l‘accord BZAJN. Ce rapport fait partie d‘une série de rapports couvrant les questions de gouvernance des océans avec un accent sur l‘Atlantique du Sud-Est (et le Pacifique du Sud-Est) publiés dans le cadre du projet STRONG High Seas - Strengthening Regional Ocean Governance for the High Seas (juin 2017 - mai 2022).

Beschreibung: Este reporte tiene como objetivo evaluar la con-tribución al bienestar humano de las activida-des socioeconómicas, actuales y potenciales, en las áreas marinas fuera de la jurisdicción nacio-nal (ABNJ por sus siglas en inglés) del Pacífico Sudeste, destacando la dependencia humana de los servicios ecosistémicos que la biodiver-sidad marina en las áreas fuera de la jurisdic-ción nacional (o BBNJ por sus siglas en inglés) provee, así como también de aquellas activi-dades que compiten en uso o bien generan efectos negativos sobre ella como consecuen-cia de su desarrollo. El estudio se focaliza en los aspectos socioeconómicos que dependen de, e interactúan con, la BBNJ en la región FAO 87, correspondiente al área f rente a las áreas juris-diccionales de Chile, Perú, Ecuador y Colombia (países miembros de la Comisión Permanente del Pacífico Sur o CPPS1), y de manera general para el bienestar de la humanidad. Como parte de esta introducción, se presenta a continuación una primera subsección que provee de contexto en relación a la importancia de los ecosistemas marinos y la relación de la BBNJ con el bienestar humano, seguida por una segunda donde se describe la organización de este reporte.

Beschreibung: While the positive impacts of renewable energy development, the implementation and use of renewable energy for people and the planet are widely recognised, the direct contribution of local renewable energy projects to local community well-being has received limited attention. And while the Paris Climate Agreement and the 2030 Agenda for Sustainable Development, with its Sustainable Development Goals (SDGs), have been rightfully celebrated as global milestones towards securing livelihoods and opportunities now and in the future, they lack societal ownership and traction among communities, who are decisive in supporting and driving the necessary sustainability transformation. However, aside from energy access, the opportunities for local energy projects to provide broader positive effects (such as community revenues) through co-investments are largely regarded as secondary co-benefits, if not entirely ignored by development policies and practices. Tapping into these opportunities for effective policies and practices in climate action and international development calls for a different approach to sustainable energy development (energy transitions in some countries): a social performance approach to energy development and investment, which we outline in this paper. In the context of this paper, the social performance of energy sector investments refers to direct and positive social impacts on the well-being of individuals and communities during the development and implementation of energy projects and the usage of locally generated energy, in both monetary and non-monetary ways. In essence, the social performance approach in energy-sector investments and energy-project development puts the needs and well-being of people – both current and future generations – at the centre of energy development and related investments and activities. The social performance approach that we propose builds on the conceptual foundations of the capability approach, the co-benefits approach, the Need–Opportunity–Ability (NOA) model, and important groundwork on community development in South Africa’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP). An important aspect of the social performance approach is its focus on the direct contribution of these investments in fostering the well-being of individuals in a manner that reflects their aspirations for good quality of life. This approach can facilitate regular evaluation of progress and ensures accountability and adjustment of implementation strategies so that future investments, design, and implementation strategies perform both for people and the planet. Social performance can be used to compare how different energy options (e.g., a coal-mining site, a renewable wind park, or decentralised energy services such as solar mini-grids) may effectively and comprehensibly improve the lives of people and local communities. The social performance approach helps to identify concrete intervention points or enablers, to ensure and increase the positive contributions of energy-sector investments to the well-being of individuals and communities, either in monetary ways such as local economic value creation and employment, or in non-monetary ways such as community cohesion and social inclusion. In this paper we suggest that, consequently, policy interventions and investments aimed at decarbonising energy systems should not simply be monitored in view of how they perform for communities and people on the ground; rather, these interventions and investments should be intentionally designed to maximise their social performance for individuals and communities.

Beschreibung: Die Klimagerechtigkeitsbewegung (KB) hat in jüngster Zeit eine erstaunliche Dynamik entwickelt und dazu beigetragen, die Klimakrise in Deutschland auf die politische Agenda zu setzen. Die sichtbarsten und mobilisierungsstärksten Bewegungsakteur*innen sind Extinction Rebellion (XR), Ende Gelände (EG) und Fridays for Future (FFF). In ihrer öffentlichen Kommunikation zur Klimakrise zeigen sich unterschiedliche thematische Schwerpunkte. Die Studie analysiert vergleichend die narrativen Strukturen von Pressemitteilungen und Blog-Artikeln von XR, EG und FFF aus dem Jahr 2019 und führt die dortigen Motive und (Mikro-)Erzählungen auf ihre jeweiligen Grundwerte zurück. Es werden Potenziale identifiziert, wie XR, EG und FFF ihre politischen Anliegen innerhalb rhetorisch überzeugenderer, (strukturell vollständigerer) Erzählungen kommunizieren können. Die Untersuchung von Klima-Frames thematisiert zudem, ob und wie ein Bezug nicht nur zu Klimaschutz, sondern zu Klimagerechtigkeit hergestellt wird.

Beschreibung: Post-pandemic recovery plans will play an important role in strengthening healthcare systems and rebuilding economies. These stimulus packages and policy responses present a unique opportunity to steer the global economy towards sustainable growth, increase resilience and bolster efforts to tackle the challenge of climate change. This IASS Discussion Paper shows how policymakers could align post-pandemic recovery planning with existing climate goals to unlock co-benefits for sustainable development and climate change mitigation and adaptation.

Beschreibung: The International Seabed Authority (ISA) is presently developing regulations (the “Mining Code”) to govern the exploration and exploitation of mineral resources of the international seabed (or “Area”). Whilst the financial mechanism is a critical component of this Mining Code, its development has been delegated to the Open-Ended Ad Hoc Working Group of the Council. These informal discussions have prioritized a model that gives preference to enabling mining over delivering fair compensation for the loss of resources. This policy brief argues that a fundamentally different and comprehensive approach is required and outlines some of its key components.

Beschreibung: Wenn die EU einen CO2-Grenzausgleich (Carbon Border Adjustment Mechanism, CBAM) einführt, könnten Länder, denen die Ressourcen für die Dekarbonisierung fehlen, schwerwiegende wirtschaftliche Folgen zu spüren bekommen. Die EU sollte daher mögliche politische Risiken berücksichtigen und Stakeholder aus Drittstaaten in die Gestaltung des CBAM einbeziehen. Sie sollte mit den CBAM-Einnahmen die Dekarbonisierung in den von Risiken betroff enen Ländern fördern und die Emissionsberichterstattung mit bestehenden internationalen Vorgaben verknüpfen.
