    Description: Since the middle of the 20th century, human society experiences a "Great Acceleration" manifesting in historically remarkable growth rates that create severe sustainability problems. The globally exploding potentials of information and knowledge exchange have been and are vital drivers for this acceleration. Society has now come to the point that it requires a "Great Transformation" towards sustainability to ensure the viability of the planet for a vital society. The energy transition plays a central role for this transformation. In this context, human society has developed a comparably good understanding of the necessary infrastructural changes of this transition. For transforming the patterns of energy production and use in an energy transition as part of the "Great Transformation", this process of change now needs to strengthen its focus on information, communication, and knowledge systems. Human society needs to establish a knowledge system that has the potential to create usable knowledge for sustainability solutions. This requires organizing a communication system that is sufficiently complex, interconnected, and, at the same time, efficient for integrating reflexive, open-ended, inter- and transdisciplinary learning, evaluation, and knowledge co-production processes across multiple levels. This challenge opens a wide field of research. This cumulative dissertation contributes to research in this direction by applying a systemic sustainability perspective on the content and organization of communication in the field of research on sustainable energy and the operational level of municipal climate action as part of the energy transition. Regarding sustainability, this thesis uses strong sustainability and its principles as a frame for evaluating the content of communication. Regarding the systemic perspective, the thesis particularly relies on the following theories: (i) the human-environment system model by R. Scholz as an overarching framework regarding interactions between humans and nature, (ii) social systems theory by N. Luhmann to reflect the complexity of society, (iii) knowledge management to consider the human character of knowledge and a practice-oriented perspective, and (iv) management cybernetics, in particular, the Viable System Model by S. Beer as a framework to analyze and assess organizational structures. Furthermore, the thesis leverages the potential of text mining as a method to identify and visualize patterns in texts that reflect prevalent paradigms in communication. The thesis applies the above conceptual and methodological basis in three case studies. Case Study 1 investigates the measures proposed in 16 municipal climate action plans of regional centers in Lower Saxony, Germany. It uses a text mining approach in the form of an Summary interpretation network analysis. It analyzes how different societal subsystems are connected at the semantic level and to what extent sustainability principles can be recognized. Case Study 2 analyzes and reflects paradigms and discursive network structures in international scientific publications on sustainable energy. The study investigates 26533 abstracts published from 1990 to 2016 using a text mining approach, in particular topic modeling via latent Dirichlet allocation. Case Study 3 turns again to the cases of municipal climate action in Lower Saxony examined in Case Study 1. It examines the involvement of climate action managers of these cities in multilevel knowledge processes. Using design principles for knowledge systems, it evaluates to what extent knowledge is managed in this field across levels for supporting the energy transition and to what extent local innovation potential is leveraged or supported. The three case studies show that international research on sustainable energy and municipal climate action in Germany provide promising contributions to achieve a transformation towards sustainability but do not fully reflect the complexity of society and still support a growth paradigm, in contrast to a holistic sustainability paradigm. Further, the case studies show that research and local action are actively engaging with the diversity of energy technologies but are lagging in dealing with the socio-epistemic (communication) system, especially with regard to achieving cohesion. Using the example of German municipalities, Case Studies 1 and 3 highlight the challenges of achieving coherent local action for sustainability and bottom-up organizational learning due to incomplete or uncoordinated multilevel knowledge exchange. At the same time, the studies also point out opportunities for supporting the required coherent multilevel learning processes based on local knowledge. This can be achieved, for instance, by strengthening the coordinating role of intermediary organizational units or establishing closer interactions between the local operational units and the national level. The thesis interprets and synthesizes the results of the three case studies from its systemic sustainability perspective. On this basis, it provides several generalized recommendations that should be followed for establishing viable communication systems, especially but not exclusively in policy-making: Systemic holism: Consider matter, energy, and information flows as an integrated triplet in the context of scales, structures, and time in the various subsystems. Knowledge society: Focus on the socio-epistemic (communication) system, e.g., using the perspective of knowledge systems and associated design principles considering, for instance, working environments across horizontal and vertical levels, knowledge forms and types, and knowledge processes. Sufficiency communication: Emphasize sufficiency approaches, make it attractive, and find differentiated ways for communicating them. Multilevel cohesion and innovation: Achieve cohesion between the local and higher levels and leverage local innovations while avoiding isolated local action. Organizational interface design: Define the role of organizational units by the interactions they create at the interfaces with and between societal subsystems. Local transdisciplinarity: Support local transdisciplinary approaches integrating various subsystems, especially industry, while coordinating these approaches from a higher level for leveraging local innovation. Digital public system: Exploit existing digital technologies or infrastructures in the public system and recognize the value of data in the public sphere for achieving cohesion. Beyond the above recommendations, this thesis suggests that potential for further research lies in: Advancing nature-inspired systemic frameworks. Understanding the structure and creation of human knowledge. Developing text mining methodologies towards solution-oriented approaches.

    Description: The transdisciplinary research mode has gained prominence in the research on and for sustainability transformations. Yet, solution-oriented research addressing complex sustainability problems has become complex itself, with new transdisciplinary research formats being developed and tested for this purpose. Application of new formats offers learning potentials from experience. To this end, we accompanied fourteen research projects conceptualized as real-world labs (RwLs) from 2015 to 2018. RwLs were part of a funding program on "Science for Sustainability" in the German federal state of Baden-Württemberg. Here, we combine conceptual and empirical work to a structured collection of experiences and provide a comprehensive account of RwLs. First, we outline characteristics of RwLs as transformation oriented, transdisciplinary research approach, using experiments, enabling learning and having a long-term orientation. Second, we outline eleven success factors and concrete design notes we gained through a survey of the 14 RwLs: (1) find the right balance between scientific and societal aims, (2) address the practitioners needs and restrictions, (3) make use of the experimentation concept, (4) actively communicate, (5) develop a "collaboration culture", (6) be attached to concrete sites, (7) create lasting impact and transferability, (8) plan for sufficient time and financial means, (9) adaptability, (10) research-based learning, and (11) recognize dependency on external actors. Characteristics and success factors are combined to illustrate practical challenges in RwLs. Third, we show which methods could be used to cope with challenges in RwLs. We conclude discussing the state of debate on RwLs and outline future avenues of research.

    Description: Practices of urban experimentation are currently seen as a promising approach to making planning processes more collaborative and adaptive. The practices develop not only in the context of ideal-type concepts of urban experiments and urban labs but also organically in specific governance contexts. We present such an organic case in the city of Wuppertal, Germany, centred around a so-called change-maker initiative, "Utopiastadt." This initiative joined forces with the city administration and collaborated with a private property owner and the local economic development agency in an unusual planning process for the development of a central brownfield site. Ultimately, the consortium jointly published a framework concept that picked up the vision of the "Utopiastadt Campus" as an open-ended catalyst area for pilot projects and experiments on sustainability and city development. The concept was adopted by the city council and Utopiastadt purchased more than 50% of the land. In order to analyse the wider governance context and power struggles, we apply the social-constructivist theory of Strategic Action Fields (SAFs). We focused on the phases of contention and settlement, the shift in interaction forms, the role of an area development board as an internal governance unit and the influences of proximate fields, strategic action, and state facilitation on the development. We aim to demonstrate the potential of the theory of SAFs to understand a long-term urban development process and how an episode of experimentation evolved within this process. We discuss the theory's shortcomings and reflect critically on whether the process contributed to strengthening collaborative and experimental approaches in the governance of city development.

    Description: Citizen science is a transdisciplinary approach that responds to the current science policy agenda: in terms of supporting open science, and by using a range of science communication instruments. In particular, it opens up scientific research processes by involving citizens at different phases; this also creates a range of opportunities for science communication to happen This article explores methodological and practical characteristics of citizen science as a form of science communication by examining three case studies that took different approaches to citizens' participation in science. Through these, it becomes clear that communication in citizen science is "always" science communication and an essential part of "doing science".

    Description: Geoarchives in ancient settlement sites and their environs bear valuable information about Holocene landscape evolution and human–environment interactions. During the last six millennia, sea-level and coastline changes have had a significant impact on coastal settlements, some of which even had to be relocated. This paper reveals new insights into the spatio-temporal development of the Lycian city of Limyra. Selected sediment cores were analyzed using a multiproxy approach, combining sedimentology, geochemistry, micropaleontology, and 14C dating. When the postglacial sea-level rise decelerated, a coastal barrier and a deep lake, presumably a lagoon, evolved after the mid-Holocene. The siltation history of the lake is complex: three coastal peat layers (mid-4th millennium BC, end of 3rd/beginning of 2nd millennium BC, beginning of 1st millennium BC), indicate periods of semiterrestrial conditions. That they are sandwiched by lake sediments is consistent with new expansion phases of the lake, most likely triggered by coseismic subsidence. There is evidence of a former lakeshore, dated to between 1400 and 1100 BC, with an intentionally deposited layer of anthropogenic remains, now at 5.5 m below the surface. In the mid-1st millennium BC, the lake silted up, river channels evolved, and people started to settle the area of the later city of Limyra.

    Description: To which extent do happiness correlates contribute to the stability of life satisfaction? Which method is appropriate to provide a conclusive answer to this question? Based on life satisfaction data of the German SOEP, we show that by Negative Binomial quasi-maximum likelihood estimation statements can be made as to how far correlates of happiness contribute to the stabilisation of life satisfaction. The results show that happiness correlates which are generally associated with a positive change in life satisfaction, also stabilise life satisfaction and destabilise dissatisfaction with life. In such as they lower the probability of leaving positive states of life satisfaction and increase the probability of leaving dissatisfied states. This in particular applies to regular exercise, volunteering and living in a marriage. We further conclude that both patterns in response behaviour and the quality of the measurement instrument, the life satisfaction scale, have a significant effect on the variation and stability of reported life satisfaction.

    Description: The target of zero emissions sets a new standard for industry and industrial policy. Industrial policy in the twenty-first century must aim to achieve zero emissions in the energy and emissions intensive industries. Sectors such as steel, cement, and chemicals have so far largely been sheltered from the effects of climate policy. A major shift is needed, from contemporary industrial policy that mainly protects industry to policy strategies that transform the industry. For this purpose, we draw on a wide range of literatures including engineering, economics, policy, governance, and innovation studies to propose a comprehensive industrial policy framework. The policy framework relies on six pillars: directionality, knowledge creation and innovation, creating and reshaping markets, building capacity for governance and change, international coherence, and sensitivity to socio-economic implications of phase-outs. Complementary solutions relying on technological, organizational, and behavioural change must be pursued in parallel and throughout whole value chains. Current policy is limited to supporting mainly some options, e.g. energy efficiency and recycling, with some regions also adopting carbon pricing, although most often exempting the energy and emissions intensive industries. An extended range of options, such as demand management, materials efficiency, and electrification, must also be pursued to reach zero emissions. New policy research and evaluation approaches are needed to support and assess progress as these industries have hitherto largely been overlooked in domestic climate policy as well as international negotiations.

    Description: Cities and municipalities have had to endure a great deal in recent years, including a global coronavirus pandemic, fire disasters in the US and devastating floods like those in Germany. These are also consequences of anthropogenic climate change, and cities have to be better prepared for such events in future. In particular, the cata-strophic flooding Germany experienced in July 2021 demonstrated how ill-equipped municipalities are for this type of incident. In this paper, we look at how cities can become more resilient, sustainable and ready for the future.

    Description: Nutrition is one of the most important areas for the great transformation. So how can a shift towards a sustainable food system be achieved? This paper addresses this question - based on more than ten years of research on sustainable nutrition at the Wuppertal Institute. It focuses on public catering, because even small changes - for example in the choice of ingredients - have a huge impact here. With appropriate policy frameworks, public catering can serve as an easily accessible place for consumers to experience sustainable food and at the same time be a reliable buyer of biodiversity and climate-friendly food from farmers. However, other actors are also needed for a transformation of the food system: The "Zukunftsimpuls" addresses politics, (agricultural) industry, science and every individual - because the transformation of the food system is a task for the entire society.

    Description: At the heart of transition research lies the question of how to "scale up" sustainable alternatives from a protected niche to the creation of mainstream practices. While upscaling processes are often seen as an essential element that contributes to societal transformation, upscaling itself remains a fuzzy concept. We argue that some fundamental dilemmas of upscaling can be identified, for example, the different understanding of the concept by researchers and practitioners. The dilemmas should be addressed in a more reflexive way by those from the worlds of science and practice who are involved in collaborative research settings.

    Description: We conducted a random allocation experiment at fashion week in Berlin in 2017, testing how face-to-face (f2f) communication affects sales of a fashion start-up focusing on second-hand. The experiment revealed that 11% of guests of an f2f event afterwards turned paying customers with an average basket size 11.8% higher than the overall sales event average. We add insights to research on entrepreneurial practice as well as on offline operations in the context of circular consumption in fashion, exposing the leveraging effect of f2f communication for customer acquisition and revenue of start-ups in the field of sustainable fashion.

    Description: Businesses like Airbnb have shown that a successful circular economy (CE) business can operate exclusively online. Although online communication and web appearance attributes have been subject to academic research given accelerated digitization, there is still a lack of knowledge about online attributes and their role in facilitating CE. We close the portrayed knowledge gap by conducting a discrete-choice experiment with best to worst scaling and focusing on the effect of CE experience on the perception of a CE website by ranking nine online attributes, grouped in three subsets. We therefore contribute by identifying online attributes that are perceived as favorable for CE businesses and detect how participation in CE activities affects the perception of these attributes. We find that third-party associated online attributes (e.g., user reviews or third-party guarantees) rank significantly higher throughout CE consumption patterns of the sample, being always amongst the top three attributes. This novel finding on online preferences opens a new direction for further research, as well as allows practitioners to optimize online operations accordingly. Furthermore, we find that users without prior touchpoints with CE have a higher need for information about the business model as compared to CE active users who are more interested in community related attributes.

    Description: This research project approached the emergence of social business innovations from the periphery, working towards the core: the first article features the representation of the concept of Social Business City, which was newly implemented by Wiesbaden in 2010. Here, social businesses are to be founded with the help of a network based on both public and private institutions. At the time of conducting the research, three such Social Business Cities existed: Wiesbaden (Germany), Fukuoka (Japan) and Pistoia (Italy); in 2016 Barcelona joined the list of Social Business Cities. The second article analyses the ways in which microfinance organisations that are based on the concept of social business according to Yunus differ from one another. Included in this research was Grameen Bank in Bangladesh, Social Business Women in Germany and Grameen America in the United States. Subsequently, a third article investigates the similarities and differences to be found between social businesses and charities. The research focuses on advantages and disadvantages on both sides and aims at answering the questions: which approach is appropriate under what circumstances and which aspects could be adopted by the other? Finally, we investigated the various cooperation of the Grameen Group with global players such as Danone, Veolia and Intel in Bangladesh and the particular challenges which result therefrom.

    Description: Automakers close factories, the stock exchange crashes, empty streets and cafés everywhere and suddenly working from home is recommended or even required for a large part of the working population in Germany. The Corona pandemic is defining our current everyday life and hitting Germany, Europe and the world at a time when there are a multitude of huge challenges to be solved already. Economic aid is indispensable during and in the aftermath of such a crisis, but the primary focus is to prevent the spread of the pandemic and limiting the health implications. Economic stimulus packages and structural aid are an effective means of overcoming the long-term economic consequences of such disruptive developments. However, they must not be distributed according to the "watering can principle"; financial support must be provided in a future-oriented manner for urgently needed investments. The aim must be to promote the necessary sustainable transformation processes within our economy and society, such as climate protection. According to the authors, the preparations must be made now. This discussion paper shows which criteria and measures are needed.

    Description: Addressing the prevailing mode of high-carbon lifestyles is crucial for the transition towards a net-zero carbon society. Existing studies fail to fully investigate the underlining factors of unsustainable lifestyles beyond individual determinants nor consider the gaps between current footprints and reduction targets. This study examines latent lifestyle factors related to carbon footprints and analyzes gaps between decarbonization targets and current lifestyles of major consumer segments through exploratory factor analysis and cluster analysis. As a case study on Japanese households, it estimates carbon footprints of over 47,000 households using expenditure survey microdata, and identifies high-carbon lifestyle factors and consumer segments by multivariate regression analysis, factor analysis, and cluster analysis. Income, savings, family composition, house size and type, ownership of durables and automobiles, and work style were confirmed as determinants of high-footprint Japanese households, with eight lifestyles factors, including long-distance leisure, materialistic consumption, and meat-rich diets, identified as the main contributory factors. The study revealed a five-fold difference between lowest and highest footprint segments, with all segments overshooting the 2030 and 2050 decarbonization targets. The findings imply the urgent need for policies tailored to diverse consumer segments and to address the underlying causes of high-carbon lifestyles especially of high-carbon segments.

    Description: This doctoral research is located in the branch of sustainability sciences that has the realisation of sustainable development as its core subject of research. The most broadly accepted notion of sustainable development is that which evolves along the resolutions, declarations, and reports from international processes in the framework of the United Nations (UN). The consensual outputs from such processes feature global-generalised and context-free perspectives. However, implementation requires action at diverse and context-rich local levels as well. Moreover, while in such UN processes national states are the only contractual parties, it is increasingly recognised that other ("nonstate") actors are crucial to sustainability. The research presented here places the attention on bottom-up initiatives that are advancing innovative ways to tackle universal access to clean energy and to strengthen small-scale family farmers. This means, the focus is on bottom-up initiatives advancing local implementation of global sustainability targets, more precisely, targets that make part of the Sustainable Development Goals two and seven (SDG 2 and SDG7). The research asks how such bottom-up initiatives can contribute to the diffusion of sustainability innovations, thereby also contributing to social change.

    Description: Background: Facing planetary boundaries, we need a sustainable energy system providing its life support function for society in the long-term within environmental limits. Since science plays an important role in decision-making, this study examines the thematic landscape of research on sustainable energy, which may contribute to a sustainability transformation. Understanding the structure of the research field allows for critical reflections and the identification of blind spots for advancing this field. Methods: The study applies a text mining approach on 26533 Scopus-indexed abstracts published from 1990 to 2016 based on a latent Dirichlet allocation topic model. Models with up 1100 topics were created. Based on coherence scores and manual inspection, the model with 300 topics was selected. These statistical methods served for highlighting timely topic trends, differing thematic fields, and emerging communities in the topic network. The study critically reflects the quantitative results from a sustainability perspective. Results: The study identifies a focus on establishing and optimizing the energy infrastructure towards 100% renewable energies through key modern technology areas: materials science, (biological) process engineering, and (digital) monitoring and control systems. Energy storage, photonic materials, nanomaterials, or biofuels belong to the topics with the strongest trends. The study identifies decreasing trends for general aspects regarding sustainable development and related economic, environmental, and political issues. Conclusions: The discourse is latently adopting a technology-oriented paradigm focusing on renewable energy generation and is moving away from the multi-faceted concept of sustainability. The field has the potential to contribute to climate change mitigation by optimizing renewable energy systems. However, given the complexity of these systems, horizontal integration of the various valuable vertical research strands is required. Furthermore, the holistic ecological perspective considering the global scale that has originally motivated research on sustainable energy might be re-strengthened, e.g., by an integrated energy and materials perspective. Beyond considering the physical dimensions of energy systems, existing links from the currently technology-oriented discourse to the social sciences might be strengthened. For establishing sustainable energy systems, future research will not only have to target the technical energy infrastructure but put a stronger focus on issues perceivable from a holistic second-order perspective.

    Description: Climate researchers agree that anthropogenic greenhouse gas emissions significantly contribute to climate change, and that radical measures to reduce greenhouse gas emissions and to adapt to the impacts of no longer avoidable climate change are needed. The German Federal Government with its Climate Protection Plan 2050 reinforced its target to reduce Germany's greenhouse gas emissions by 80 to 95 percent compared with 1990. The achievement of these targets requires nothing less than a fundamental transformation of spatial planning. In the paper a methodology to scientifically assess the likely impacts of possible combinations of policies or strategies to achieve the energy transition, i.e. to reduce the greenhouse gas emissions of urban mobility and transport is proposed and demonstrated, using the Ruhr Area, the largest conurbation in Germany, as an example. The results of the policies examined so far can be summarised as follows: Push measures as high energy prices, speed limits or reduction of the number of lanes of main roads are more effective in reducing greenhouse gas emissions than pull measures as the promotion of cycling, walking, electric cars or public transport. Between policies or policy packages there can be positive or negative synergies, i.e. the impacts of measures can reinforce or weaken each other. The results show that even with ambitious policies the greenhouse gas emission targets of the national and state governments will not be achieved and that more radical policies are needed.

    Description: The decarbonisation of the building stock is an important element for the success of the German Energiewende (energy transition). Despite some progress having been made, the rate of energy renovation falls below the level required to meet political commitments. This gives rise to the question: what deters property owners from making energy efficiency investments and how can the policy framework foster such investments? To answer this question, the paper focuses on a widely neglected property owner group: small private landlords (SPL). Although they manage 37% of all residential rental properties in Germany, very little is known about their decision-making processes for energy efficiency investments. We applied a mixed-method design to identify factors that hindered and supported their investments. In an explorative study, we initially conducted 18 problem-centred interviews. Subsequently, we carried out a postal survey and analysed the questionnaires using a hierarchical linear regression model. The results show that energy renovation is a multi-dimensional decision-making process, which can only be adequately addressed by a comprehensive policy package. To develop such a package, the author recommends that the specific investment behaviour of SPL must be better targeted, their knowledge about energy efficiency investments must be improved through exchange and networking, a sense of responsibility for the neighbourhood must be fostered, and greater focus must be placed on improving local framework conditions

    Description: As part of the lagoon barrier accretions plain characterizing the NW coast of the Peloponnese, the Kotychi Lagoon is believed to have formed in the prograding delta of the Palaeo-Peneus River over 7000 years ago. Geochemical/sedimentological proxies-data (XRF, grain size, OC-, IC-, C/N-analysis) combined with Bayesian age-depth-modeling revealed that from 8500 to 8000 cal BP marine conditions were prevailing. Around 8000 cal BP, a short-lived sequence of coastline progradation and barrier accretion created lagoonal conditions. Thus, the first chronological control for the onset of lagoon formation in coastal Elis is presented. Pronounced lagoonal conditions developed approximately 6300 cal BP, simultaneously to the period of circum-Mediterranean lagoon formation. A rapidly varying sedimentary record indicates a phase of geomorphological instability between 5200 and 3500 cal BP terminating with the erosional unconformity of a river channel. This evolution reflects a two-phase development: (1) Early Holocene morphology was controlled by the postglacial sea level rise; (2) with receding of the ice sheets by mid-Holocene, the preeminent role of the eustatic signal was overwhelmed giving local and regional processes, such as human-induced soil erosion and climatic forcing an accentuated role. Thus, the evolution of the Elean coastline shows analogies to circum-Mediterranean lagoon formation.

    Description: The Zoolithen Cave, in the Wiesent River Valley of Upper Franconia, Bavaria, South Germany, has a very long excavation history. The site is of international paleobiological importance as the Type site for five Pleistocene top predators (cave bear, Ice Age hyena, lion, wolf, dhole). This large cave system has developed in three elevations and preserves three fluvial sedimentary sequences including two speleothem genesis phases representing changing ponor, dry and wet stages from the Oligocene/Miocene (Neogene), over the Pliocene/Early Pleistocene to Late Pleistocene. The cave bear Ursus deningeri used the cave as den during the MIS 6–9 (Holsteinian interglacial-Saalian glacial). Single P4 tooth and skull shape analyses (“= cave bear clock”) date different cave bear species (U. spelaeus eremus/spelaeus, U. ingressus) within the Late Pleistocene (MIS 3–5d). Finally the bones of other Pleistocene megamammals were washed from two former cave entrances at elevations of about 455 m a.s.l. up to 30 meters deep into lower elevation cave parts, during the Last Glacial Maximum (Post-U. deningeri times or Postglacial), -historically believed to be the result of the “great deluge”. The young “river terrace dolomite gravels” which occur as relic sediments at elevations of about 455 a.s.l in several caves around Muggendorf cannot be explained by natural erosion/river terrace stratigraphy, and must relate to an uncertain glacial context. Finally Iron Age (La Tène) humans left secondary burials (human skulls and long bones with pottery and after-life food animal donations) only in the first deep vertical shaft (Aufzugsschacht) similar to the situation in the nearby Esper’s Cave.

    Description: Exotic ice-rafted debris from the breakup of ice-dammed glacial lakes Missoula and Columbia is common in slackwater areas along the 1,100-km route for outburst floods in the northwestern US. A detailed analysis was performed at Rattlesnake Mountain, which lay beyond the limit of the former ice sheet, where an exceptionally high concentration of ice-rafted debris exists midway along the floods’ path. Here floodwaters temporarily rose to 380 m elevation (forming short-lived Lake Lewis) behind the first substantial hydraulic constriction for the outburst floods near Wallula Gap. Within the 60 km2 study area more than 2,100 erratic isolates and clusters, as well as bergmounds were recorded. Three quarters of erratic boulders are of an exotic granitic composition, which stand in stark contrast to dark Columbia River basalt, the sole bedrock in the region. Other exotics include Proterozoic quartzite and argillite as well as gneiss, diorite, schist and gabbro, all once in direct contact with the Cordilleran Ice Sheet to the north. Most ice-rafted debris is concentrated between 200 and 300 m elevation. Far fewer erratics and bergmounds lie above 300 m elevation because of the preponderance of less-than-maximum floods. Plus, larger deep-rooted icebergs were forced to ground farther away from the ancient shorelines of transient Lake Lewis. As floodwaters moved across the uneven surface of Rattlesnake Mountain, many erratic-bearing icebergs congregated into pre-existing gullies that trend crosswise to flood flow.

    Description: It is widely accepted that environmental awareness is essential, yet does not inevitably lead to responsible use of resources. Additional factors on the individual level include the meaning constructed by the term "resources" and the individual and social norms that influence the relevant behavior. Current didactic concepts do not take into account such aspects. Therefore, this article uses a didactic-psychological approach for designing an educational concept for raising awareness for a responsible use of natural resources. Combining insights of environmental psychology and of constructivist didactics, a general principal of "norm-oriented interpretation learning" is outlined to enrich the didactic debate on responsible and efficient resource use. Based on the presentation of a qualifying module for resource efficiency consultants as a practical example of resource education, a new didactical approach, namely "open-didactic exploration" (short form: ODE) is introduced. The article discusses the theory-based elements of ODE and illustrates a step by step process for designing educational materials. This adds to the theoretical debate about a didactic design for resource oriented education. Furthermore, this method can be directly used by practitioners developing education and training material (e.g., teachers, trainers in vocational education). The Wuppertal Institute developed and applied this method in numerous projects. The conclusion and outlook discusses future expectations and scope of the introduced ODE method as a contribution to foster "norm-oriented interpretation learning", suggesting perspectives for further development.

    Description: The year 2015 has special importance for the transformation towards sustainable development. New Sustainable Development Goals (SDGs) are then supposed to replace the Millennium Development Goals (MDGs). The aim is to offer a new orientation for political action in the coming decades. The WBGU recommends orienting the new catalogue of goals towards the key message of the 1992 Earth Summit: that development and environmental protection must be considered together and do not contradict each other. The SDGs should not be reduced to poverty eradication, but must address all dimensions of sustainable development. In particular, global environmental change must be incorporated, otherwise even poverty eradication will become impossible. Up to now, too little attention has been paid to this link in the ongoing discourse on SDGs. Although many reports mention the concept of planetary guard rails or planetary boundaries, they do not back this up with specific targets. The WBGU presents recommendations on how guard rails for global environmental problems should be incorporated in the SDG catalogue and operationalized by means of corresponding targets.

    Description: Access to sustainable and affordable energy services is a crucial factor in reducing poverty in developing countries. In particular, small-scale and community-based renewable energy projects are recognized as important forms of development assistance for reaching the energy poor. However, to date only a few empirical evaluations exist which analyze and compare the impact of these projects on local living conditions and their sustainability ex-post implementation. To better understand the impacts and the conditions that influence sustainability of these projects, the research presented in this paper evaluated 23 local development projects post implementation. By applying an standardized evaluation design to a cross-sectional sample in terms of renewable energy sources (solar, wind, biomass, hydro), user needs (electricity, food preparation, lighting, productive uses), community management models, finance mechanisms and geographical locations, the review results provide valuable insights on the underlying conditions that influence the success or failure of these small-scale local energy interventions. The empirical evidence suggests that the sustainability of small-scale energy implementations (≤100 kW) in developing countries is determined by the same factors, independent of the socio-cultural, political and ecological context. These findings allow to better predict the long-term success of small sustainable energy projects in developing countries, this can help to improve project designs and increase the certainty for future investment decisions.

    Description: In contrast to the original investigation by William Stanley Jevons, compensations of energy savings due to improved energy efficiency are mostly analyzed by providing energy consumption or greenhouse gas emissions. In support of a sustainable resource management, this paper analyzes so-called rebound effects based on resource use. Material flows and associated expenditures by households allow for calculating resource intensities and marginal propensities to consume. Marginal propensities to consume are estimated from data of the German Socio-Economic Panel (SOEP) in order to account for indirect rebound effects for food, housing and mobility. Resource intensities are estimated in terms of total material requirements per household final consumption expenditures along the Classification of Individual Consumption according to Purpose (COICOP). Eventually, rebound effects are indicated on the basis of published saving scenarios in resource and energy demand for Germany. In sum, compensations due to rebound effects are lowest for food while the highest compensations are induced for mobility. This is foremost the result of a relatively high resource intensity of food and a relatively low resource intensity in mobility. Findings are provided by giving various propensity scenarios in order to cope with income differences in Germany. The author concludes that policies on resource conservation need to reconsider rebound effects under the aspect of social heterogeneity.

    Description: A decent, or sufficient, lifestyle is largely considered an important objective in terms of a sustainable future. However, there can be strongly varying definitions of what a decent lifestyle means. From a social sustainability point of view, a decent lifestyle can be defined as the minimum level of consumption ensuring an acceptable quality of life. From an ecological sustainability point of view, a decent lifestyle can be defined as a lifestyle that does not exceed the carrying capacity of nature in terms of natural resource use. The paper presents results of a study on the natural resource use of 18 single households belonging to the lowest income decile in Finland. The yearly "material footprint" of each household was calculated on the basis of the data gathered in a questionnaire and two interviews. The results show that the natural resource use of the participating households was lower than the one of the average consumer. Furthermore, 12 of 18 households had a smaller material footprint than the "decent minimum" reference budget defined by a consumer panel. However, the resource use of all the households and lifestyles studied is still higher than long-term ecological sustainability would require. The paper concludes that the material footprint is a suitable approach for defining and measuring a decent lifestyle and provides valuable information on how to dematerialize societies towards sustainability.

    Description: Among the factors that decelerate progress of CCS demonstration and deployment is the lack of public acceptance of local projects in Germany as well as in other countries. The study presented here aims to take the issue of public CCS perceptions further by empirically investigating the relevance of different specifications of the three main steps of the CCS chain, i.e. capture, transport and storage. An experimental approach is chosen and applied in an online survey with a representative sample from Germany with 1830 participants. With regard to possible CO2 sources we varied whether the CO2 of a specific setting is captured i) as part of an energy-intensive industry process (e.g. production of steel or cement), ii) from a power plant running on biomass, or iii) a coal-fired power plant. For transport, half of the settings described made reference to transport of CO2 via pipelines, the other half did not provide information about transport. With regard to storage the setting descriptions i) either explained that CO2 can be stored in saline aquifers, ii) can be used to enhance gas production from an emptying natural gas field or iii) can be stored in a depleted natural gas field. We find that overall the average of the ratings for perception of the settings fall into the neutral part of the answering scale. If the source of CO2 is a coal-fired power plant the setting is perceived less positively than if it includes biomass or industry. A significant interaction effect between transport and storage specifications is observed. This points out that storage in saline aquifers is perceived more negatively than a combination with enhanced gas recovery while storage in a depleted natural gas field is rated less positively if a pipeline is mentioned and more positively if no transport option is mentioned.

    Description: Changing consumer behaviour is key to reducing the environmental effects of industrialised societies. Social practice theories provide an integrated approach to understanding consumer behaviour. The mechanisms underlying the emergence and diffusion of social practices are however until now poorly understood. This paper presents a conceptual framework and an abstract agent-based simulation model for generating social practices which use and extend approaches from social practice theories. The main results are twofold. First, the simulation model is able to generate social practices, what confirms that the conceptual framework captures relevant elements and processes. Second, a new mechanism for behavioural lock-in is identified that provides additional insights into the widely acknowledged challenge of changing social practices and respective consumption.

    Description: Since in 1992 the United Nations Conference on Environment and Development (UNCED) has been held in Rio de Janeiro, efforts to achieve sustainable development appear to have made only insufficient progress, as the results of the 2012 follow-up conference show. One reason for this is that among the various paths to sustainability being discussed, the strategies enjoying greater support are those that continue to be committed to economic and material growth, this as opposed to those that question the growth paradigm. Among the latter are the sufficiency and subsistence approaches. The sufficiency approach delves into the causes and (supposed) boons of a continuous increase in material and immaterial goods. With the demand that individuals not always be forced to always want more, it points out a way to a structural transition in society. The subsistence approach, on the other hand, seeks to draft a path to greater autonomy and quality of life by strengthening regional, local or indi-vidual self-provisioning. To be in harmony with sustainability, it must be possible to freely choose the two ways of life; they must not be mandated by the authorities.

    Description: This guidebook - developed by the Wuppertal Institute - is meant to accomplish two things: i) to provide some hands-on examples of how the transformational impact of capacity development activities can be enhanced and ii) to give some guidance on identifying which activities should be funded. Applying these guidelines will (hopefully) help to create the enabling conditions needed to increase the transformational impact of climate finance. Moreover, this guidebook should be seen as a bridge between the work of development cooperation and the global debate on transformation by giving guidance and demonstrating the practical value of this concept.

    Description: The diversification of the national electricity generation mix has risen to the top of Tunisia's energy planning agenda. Presently, natural gas provides 96% of the primary energy for electric power generation, but declining domestic gas reserves and a soaring electricity demand are urgently calling for alternative fuel strategies. Currently discussed diversification options include the introduction of coal and nuclear power plants and/or an increased use of renewable energies. This article presents a methodology to assess different electricity system transformation strategies. By combining an electricity market model with a subsequent multi-criteria decision analysis (MCDA), we evaluate five power mix scenarios regarding power generation costs as well as non-economic dimensions such as energy security, environmental impact and social welfare effects. Based on criteria valuations obtained during consultations with Tunisian stakeholders, a final, best-ranking electricity scenario was selected, consisting of 15% wind, 15% solar and 70% natural gas-generated electricity in the national power mix by 2030.

    Description: A book promoting policies to make it easier to live the Good Life must do two things. Firstly, it must demonstrate that such policies are necessary; secondly, it must set out how such a policy programme is to be implemented. In other words, it has to show that the politics of sufficiency is feasible. "The Politics of Sufficiency" deals with claims of feasibility, and with the objections to them. It demonstrates that a politics of the Good Life can be both justified and legitimated in modern free democratic societies - indeed, that it is an essential condition of such societies. The main section of the book sets out in detail how such a politics can be implemented, organised along four political dimensions. At the same time, this book can only represent a beginning, and that is its aim - a starting-point for a broad discussion over the coming years.

    Description: The use of models to study the dynamics of transitions is challenging because of several aspects of transitions, notably complexity, multi-domain and multi-level interactions. These challenges are shared by other research areas that extensively make use of models. In this article we survey experiences and methodological approaches developed in the research areas of social-ecological modeling, integrated assessment, and environmental modeling, and derive lessons to be learnt for model use in transition studies. In order to account for specific challenges associated with different kinds of model applications we classify models according to their uses: for understanding transitions, for providing case-specific policy advice, and for facilitating stakeholder processes. The assessment reveals promising research directions for transition modeling, such as model-to-model analysis, pattern-oriented modeling, advanced sensitivity analysis, development of a shared conceptual framework, and use of modeling protocols.

    Description: Both focus group discussions and information-choice questionnaires (ICQs) have previously been used to examine informed public opinions about carbon dioxide capture and storage (CCS). This paper presents an extensive experimental study to systematically examine and compare the quality of opinions created by these two research techniques. Depending on experimental condition, participants either participated in a focus group meeting or completed an ICQ. In both conditions participants received identical factual information about two specific CCS options. After having processed the information, they indicated their overall opinion about each CCS option. The quality of these opinions was determined by looking at three outcome-oriented indicators of opinion quality: consistency, stability, and confidence. Results for all three indicators showed that ICQs yielded higher-quality opinions than focus groups, but also that focus groups did not perform poor in this regard. Implications for the choice between focus group discussions and ICQs are discussed.

    Description: Current well-being research often overlooks human dependency on natural resources and undervalues the way environmental impacts affect human activities. This article argues that the capability approach provides an applicable framework for inquiring into ecologically sustainable well-being. Therefore, this pilot study aims to develop a research method for integrating the measurement of natural resource use with capability-based well-being research. Semi-structured interviews were carried out with 18 Finnish minimum income receivers and their natural resource use (material footprints) was measured in five central functionings by using the Material Input Per Unit of Service (MIPS) method. The connections between capabilities, functionings and material footprints are interpreted from a person-centered perspective in order to explain the individual variety in material footprints. The results show that the material footprints of minimum income receivers are smaller than with an average Finn but they still exceed what is estimated to be an ecologically sustainable level of natural resource use.

    Description: Resource efficiency in production and technological innovations are inadequate for considerably reducing the current use of natural resources. Both social innovations and a complementary and equally valued strategy of sustainable consumption are required: goods must be used longer, and services that support collaborative consumption (CC) patterns must be extended. "Using rather than owning" strategies, such as product sharing, have the potential to conserve resources. Based on the results of different German studies, this article highlights the resource-saving potentials of CC patterns and recommendations proposed for policies and further research questions. The purpose of this paper is to show that a general resource-saving potential can be realized by "use rather than own" schemes, depending on the application field and the framework for implementation. CC is suitable for making a positive contribution to achieving the Factor 10 target by playing an important role in changing consumer patterns.

    Description: This paper argues that the contemporary growth paradigm needs to be reconsidered on a micro level of consumption and product service-systems. This becomes necessary since a dynamic link between macro strategies and micro implementation of sustainable growth is missing up to date. Therefore, mainstream sustainability strategies of efficiency and consistency are extended by sufficiency in order to integrate strategies for individual welfare within their social environment. Limits to and drivers for growth are revised and updated socially in terms of qualitative values, diminishing marginal utility or symbolic social distinction. We elaborate a definition of sustainable growth that fosters individual welfare by enhancing social enactment within the boundaries of environmental space. Shifting focus on social aspects in design fosters more sustainable production and consumption patterns while sustaining individual welfare. We derive latent indications for eco-intelligent product service-arrangements and evaluate to concepts by referring to introduced definitions and according indications. With doing so, we illustrate new pathways for the translation of sustainable growth and strategies into product service-systems.

    Description: This chapter addresses material leakage as a major problem of international open markets for used goods, in particular for used vehicles. It develops elements of an international metal covenant that should allow for a more sustainable management of global material flows in that area. The arguments in favour of such a proposal are as follows: Any regulation should actively seek for industry participation, taking advantage of business interest in supplying a sufficient amount of materials while lowering materials cost. It should also address public issues such as sustainability of recycling and waste. A first section analyses contracts as a tool to overcome knowledge problems that occur when many actors are involved. A second short section gives empirical evidence for material leakage in the case of used vehicles from Germany. A third section develops elements of an international metal covenant. A fourth section analyses potential impacts and discusses legal and institutional issues. Finally, some conclusions are drawn.

    Description: The need for recycling obsolete mobile phones has significantly increased with their rapidly growing worldwide production and distribution. Return and recycling rates are quite low; people tend to keep old, unused phones at home instead of returning them for recycling or further use because of a lack of knowledge and acceptance of return programmes. Thus far, individual use and recycling behavior has not shown any trend towards more sustainable patterns. Consequently, an increased awareness is needed for the high environmental and social impact throughout the whole value chain of a mobile phone - there is simply a lack of information and knowledge regarding sustainability issues around the mobile phone. A teaching material was therefore developed in a German research project, based on the concept of the ecological rucksack, presenting comprehensive information about the value chain of a mobile phone. Its application in different schools led to an increased awareness and interest among pupils for the connection between sustainability, resources and mobile phones. Based on these research results, this paper analyses young people’s knowledge of sustainability issues linked to their mobile phones and their acceptance of more sustainable behavioral patterns regarding their mobile, including return and recycling programmes.

    Description: In communication sciences partnerships between entertainment media professionals and sustainability organizations conveying prosocial messages are called "Entertainment-Education (E-E) collaborations". Whereas comprehensive research takes place in countries such as the Netherlands and the US, the field is a terra incognita in Germany. Even though German E-E collaborations are designed and implemented they still are unusual experiments. The qualitative study presents first results on characteristics, conditions and forms of E-E collaborations in Germany's television field since the 1990s. It reveals various factors leading to a highly complex situation for the collaborating partners. One central factor is the media legislation, which does not provide a clear orientation standard for the partners. Another one is the public acceptance of E-E collaborations. Some forms are accepted while others are not. Hence, for German television formats, forms with a low to medium level of collaboration (E-E service and E-E license partnerships) should be preferred in contrast to high level collaboration forms (E-E co-productions and E-E inscript participations).

    Description: The article argues for a need to overcome a conventional notion of product design. In this regard, the article offers an integrative and systemic approach to sustainable design. Instead of focusing on objects, a user-centred perspective is adopted. A sustainable design of products and services requires the integration of production-orientated (efficiency and consistency) and consumption-orientated (sufficiency) strategies. The article introduces the concept of an indicator that is capable of comprehending a lifecycle-wide analysis of products and that favours the integration of existing sustainability strategies. The goal is not to design sustainable products but rather to design systems that manage to foster sustainable lifestyles. The article illustrates the usability of the introduced concept by showing examples of strategic integrative thinking in sustainable design from the Sustainable Summer Schools.

    Description: A cost-minimizing electricity market model was used to explore optimized infrastructures for the integration of renewable energies in interconnected North African power systems until 2030. The results show that the five countries Morocco, Algeria, Tunisia, Libya and Egypt could together achieve significant economic benefits, reaching up to EUR 3.4 billion, if they increase power system integration, build interconnectors and cooperate on joint utilization of their generation assets. Net electricity exports out of North Africa to Europe or Eastern Mediterranean regions, however, were not observed in the regime of integrated electricity markets until 2030, and could only be realized by much higher levels of renewable energy penetration than currently foreseen by North African governments.

    Description: Our perception of design is changing, for design today is no longer concerned only with aesthetics. Now the key factors are interdisciplinary competence and approaches to problem solving. Both politicians as well as businesses recognise design's hybridity and increasingly implement it as a driver of sustainable development (see Chap. 2: Design as a Key Management Factor for Sustainability). But what exactly does "sustainability" mean? What does it mean in this specific context? People must make use of natural resources to meet their basic needs. In this process, resources are transferred into commercial circulation and usually transformed into products with a particular function. Yet the environment is limited and humanity uses more resources than the Earth can sustainably provide. It is time to rethink and generate the same usage while consuming fewer resources (see Chap. 3: Environmental Space - Challenging Transitions). Most countries have incorporated sustainability strategies into their political agendas in order to counteract the threats of climate change caused by the overuse of natural resources, high CO2 emissions, and other factors. The indicators for these strategies vary greatly from country to country (see Chap. 4: Sustainability - Challenges, Politics, Indicators). These indicators need to be taken into account if we are to successfully implement a product or service within a specific context. A concept can only be successful when country-specific indicators are taken into account and the societal context is incorporated into the plan right from the start. The goal is to develop services that support national sustainability targets in production and consumption systems (see Chap. 5: Managing Sustainable Development). When it comes to companies, these changes can simply be introduced in the form of services or products. In the end, it is the users who decide on the success or failure of innovative solutions by either integrating them into their daily lives or ignoring them. Solutions will only be integrated into users' lives when their role within the social framework remains unchallenged by behavioural transformations caused by use of the solution. In order for users to be able to adopt innovations, sustainable development must take place simultaneously on many different levels. These multi-levelled transitions allow for the transformation of society as a whole. Designers can act as agents of change by providing the needed innovations (see Chap. 6: Transition Requires Change Agents for Sustainability). If we are to develop suitable solutions and new approaches, the real needs have to be analysed at the beginning of the development process. New physical products, which frequently result in auxiliary products, are often developed without taking into account the overall context, whereas the development of service-orientated solutions is ignored. A physical product is not absolutely necessary. A service (which is naturally dependent on physical products) can usually fulfil the need just as well - or perhaps even better and at a lower cost – while using fewer or no resources (see Chap. 7: Needs & Services - An Approach). There are a variety of possible approaches to integrate sustainability into the design process (see Chap. 8: Design Process). Precisely which solution is "most or more sustainable" (this is dependent on the defined targets and the indicators used) is often not immediately obvious, and we must turn to a set of methods for a transparent and tangible assessment (see Chap. 9: Sustainability Assessment in Design - Overview and Integration of Methods).

    Description: Another summit of change, known as Rio+20, has passed in summer 2012, nourishing the rumours of a green economy. Building up a green economy seems to be the all over recipe for different crises of capitalism, among them climate change and resource scarcity. Yet efficiency and consistency, as their main strategies, do not suffice to reach sustainable levels, as they cause rebound effects and keep stimulating economy growth. Obviously, there are limits to green growth, too. Can we conceive an economy, and respective economic institutions, that serve human needs and wealth without a built-in necessity to grow? What kind of political, mental, and individual changes does a sufficiency economy require? And what are perspectives and policies to actually start implementing it? Just before Rio +20 the symposium "Economy of Sufficiency", devoted to Wolfgang Sachs on the occasion of his 65th birthday in 2011, examined these questions in three dimensions. Accordingly this selection of contributions to the symposium follows the chapters "Wealth in diversity" (Ashok Khosla, Marianne Gronemeyer, Vandana Shiva), "Enjoyable limits" (Richard B. Norgaard, Tim Jackson) and "Creating commons" (Ezio Manzini, Silke Helfrich). The essays indicate the historical development of the ideas on a sufficiency economy. Wandering through discourses of sustainable development for several decades, the authors map the range of perspectives, practices as well as barriers and bridge them between cultures, agencies and schools.

    Description: "Planet Dialectics" explores the ambivalences and ironies, the controversies and conflicts that pervade the terrain of global environmental politics. Most inquiries turn around one nagging suspicion: that the Western development model is at odds with both the quest for justice among the world's people and the aspiration to reconcile humanity and nature. By any stretch of imagination, it will not be possible that all citizens of the world will share in the fossil fuel-based, money-driven development model - with all its attendant paraphernalia - that has come to hold sway in the world today. The biosphere, as we know it, may give in. Against this background, the book probes Western-style development, examines its hidden assumptions, its glamour, its obsessions and the hopes it holds out for a better life. Moreover, it examines under various aspects if sustainability (truly conceived) - comprising both ecology and social fairness - is incompatible with the worldwide rule of economism. And finally, it suggests ways to leave conventional modernity behind by creating sophisticated but moderate-impact technologies, redirecting relentless accumulation, and appreciating ways of living that are simpler in means, but richer in ends.

    Description: Die Lokalität Schwalbenberg bei Remagen am Mittelrhein erschließt ein sehr vollständiges Profil durch den letztglazialen Löss mit drei Großgliedern. Gut gegliedert sind der Löss der Keldach-Formation (Früh-Weichsel/Würm-Hochglazial, MIS 4) mit einem Interstadial-Boden und der Löss der Ahrgau-Formation (Mittelweichsel/-Würm-Interstadial-Komplex, MIS 3) mit acht Interstadial-Böden. Den Abschluss nach oben bildet weniger gut gliederbarer Löss des Jung-Weichsel/Würm-Hochglazials. Zu bereits veröffentlichten organischen Kohlenstoff (Corg)- und Phosphor-Kurven einer ersten Profilaufnahme, Schwalbenberg I, präsentiert dieser Text Daten des Profils Schwalbenberg II: AMS 14C-Datierungen, Korngrößen, Corg- und Karbonatgehalt. Die Korngrößen spiegeln die Dreigliederung wider mit Grobsilt-ärmerem Keldach-Löss, schwankendem Siltgehalt im Ahrgau-Löss und Grobsilt-reicherem Jungwürmlöss. Auch im Karbonatgehalt spiegelt sie sich mit Karbonat-ärmerem Keldach-Löss, schwankenden Gehalten im Ahrgau-Löss und Karbonat-reicherem Jungwürmlöss. Die neun interstadialen Böden erweisen sich durch Corg-Gipfel und Karbonat-Minima vereinigt mit pedogener Zonierung bodenintern von oben nach unten als autochthone Böden. Alle Nassböden zeigen Karbonatmaxima. Der Vergleich der Corg-Kurve mit der der δ18O-Kurve des jahrring-zonierten grönländischen Eiskerns GISP 2 zeigt für die Ahrgau-Formation – wie früher schon die Kurven vom Schwalbenberg I – erneut nach Kurvenrhythmik und Magnitude hohe Gleichläufigkeit des Klimaverlaufes zu den Grönland-Interstadialen 17 bis 5. Nummerische Daten vom Schwalbenberg II unterstützen das weitgehend. Zur Frage, ob die Grenze Mittel-/Oberwürm (MIS 3/MIS 2) nach dem obersten braunen Boden (Sinzig 3-Boden) oder wenig höher mit der Hesbaye-Diskordanz zu ziehen ist, sprechen die meisten lithologischen und die chronologischen Kriterien für die Grenzziehung an der Hesbaye-Diskordanz. Ansonsten ist der Schwalbenberg unter den gut vergleichbaren Lössprofilen im westlichen Europa bisher das am detailliertesten gegliederte MIS 3-Profil. Reicher gegliedert sind nur Lössprofile des kontinentaler geprägten Raumes in der nordöstlichen Karpatenregion und in Sibirien.

    Description: Anhand von 18 Kurzkernen aus der Talsperre Lehnmühle (Inbetriebnahme 1932) im Osterzgebirge (Deutschland) wurden mittels mikrofaziellen und hochauflösenden μ-XRF Scanning Verfahren Auswirkungen des extremen Augusthochwassers 2002 auf den Sedimenteintrag untersucht. Fast über den gesamten Talsperrenboden hinweg wurde eine für die gesamte Sedimentsequenz einmalig markante detritische Lage detektiert, welche eine Mächtigkeit von 5 mm an der Staumauer bis 33 mm nahe dem Zufluss misst. Die eingetragene Sedimentmenge dieser Lage wird auf ca. 2.400 Tonnen geschätzt, wovon etwa zwei Drittel im südlich-zentralen Teil des Beckens (ca. 32 % der Gesamtfläche) abgelagert wurden, begründet durch die Beckenmorphologie und die Lage zum Zufluss. Feine Silt- und Tonpartikel wurden dagegen vornehmlich weiter in Richtung Staumauer transportiert, forciert durch eine ständige Wasserströmung durch das Staubecken. Eine erhöhte Akkumulation von detritischem Material in einer seitlichen Bucht zeigt, dass Sedimente nicht nur durch den Hauptzufluss eingetragen wurden, sondern ebenfalls durch Oberflächenabfluss in nicht ständig wasserführenden Rinnen um die Talsperre herum. Neben der markanten Lage des Jahres 2002, wurden 22 weitere, mikroskopisch dünne detritische Lagen in den Sedimentkernen nachgewiesen, die meisten im Profundalbereich nahe der Staumauer. Eine Chronologie der detritischen Lagen wurde an drei 137Cs datierten Kernsequenzen erstellt und durch detaillierte Korrelation mittels vier lithologischer Marker auf die übrigen Kerne übertragen. Der Vergleich mit instrumentellen Abflussdaten des Hauptzuflusses zeigt, dass während der letzten drei Jahrzehnte 64 % von insgesamt 22 Hochwasserereignissen mit einem Tagesabfluss 〉 8 m3s-1 in die Ablagerung von detritischem Material resultierten.

    Description: Im Einzugsgebiet des ‘Giessenbaches’ (Nördliche Kalkalpen, NKA) lagerte sich eine mächtige Sedimentabfolge während bis wenig nach dem Zerfall des hochglazialen Eispanzers ab. Das Einzugsgebiet liegt auf gestörten, geklüfteten triassischen Dolomitgesteinen. Die quartäre Abfolge besteht aus, (a) aufgearbeitetem Till mit Leitgeschieben des Letzten Glazialen Maximums (LGM), (b) alluvialen Kiesen, die vom Dolomitgesteins-Untergrund gespeist wurden, (c) Decklagen von Flusssedimenten auf Terrassen, und (d) grossen Schutthalden. Die ehemalige (Vor-LGM) obere Hälfte des Giessenbach-Laufs ist noch heute ein trockenes, erhöhtes Tal das wesentlich durch spätglaziale bis holozäne Sedimente verfüllt ist. Der heutige Giessenbach zeigt ein konvexes Längsprofil mit einer Klamm im Unterlauf; diese Klamm war wahrscheinlich teilweise durch Toteis versperrt während die Sedimentation der Eiszerfallsphase bereits eingesetzt hatte. Außer glazial überformten Felsflächen und ehemaligen Nunatakkern ist die heutige Morphologie des Einzugsgebiets im wesentlichen bestimmt durch (a) einen ‚Schub‘ sehr rascher Sedimentation vom Eiszerfall bis ins ?frühe Spätglazial, gefolgt von (b) Hangstabilisierung durch Bewachsung, und Einschneiden von Gerinnen. Die rasche Sedimentation wurde durch den Untergrund aus tektonisch verformtem Dolomitgestein gefördert, das unter reichlicher Schuttbildung abwittert. Ähnliche Verläufe von rapider Sedimentation vom Eiszerfall bis zum Spätglazial hin zu einem längeren Zeitabschnitt vorwiegend mit Einschneiden von Gerinnen sind in den NKA weit verbreitet.

    Description: Eine klassische weichselspätglaziale Lokalität ist die kleine Toteishohlform des Niedersees, welche direkt an der südöstlichen Küste der Halbinsel Jasmund (Rügen, Ostsee) aufgeschlossen ist. Neue Studien wurden durchgeführt, bei denen sich die sedimentäre Abfolge des Niedersees als ein hervorragendes Archiv für paläoökologische/-klimatische Rekonstruktionen erwies, wodurch detaillierte Aussagen zur regionalen Vegetationsgeschichte sowie zum regionalen Klima und Milieu während des Weichselspätglazials und auch teilweise für das Holozäns möglich sind. Mit Hilfe der Pollenstratigraphie, AMS 14C-Datierungen und dem Nachweis der Laacher See Tephra konnte die sedimentäre Abfolge in die bestehende Quartärstratigraphie eingehängt werden; als Besonderheit ist hier das quasi gesamte Weichselspätglazial vollständig aufgeschlossen. Die Sedimentation beginnt schon im ausgehenden Weichselhochglazial und dauert zunächst bis zum Präboreal an (~15.000–~10.000 Jahre v. H.) und ist vor allem durch Ablagerungen eines kleinen, flachen Sees charakterisiert. Änderungen im Wasserhaushalt führten letztendlich während des Präboreals zu einem Hiatus. Eine letztmalige Vernässung des Standorts führte im Atlantikum zur Entwicklung eines kalkigen Niedermoors. Die sich ergänzenden Analysen der verschiedenen und vielfältigen Organismenreste des Niedersees (z. B. Pollen, Ostracoden, Mollusken, Makroreste von Pflanzen etc.), erlaubten in sehr detaillierter Weise Änderungen im Klima und deren Auswirkungen auf das Habitat zu erfassen.

    Description: Gegenstand dieser Studie ist die würm-spätglaziale und holozäne Talentwicklung am Zusammenfluss von Lech und Donau im Nördlichen Alpenvorland. Die morphologischen Formen im Untersuchungsgebiet wurden mit Hilfe von Geländekartierungen und digitalen Geländemodellen aufgenommen. Die Ablagerungen beider Flüsse wurden in zahlreichen Aufschlüssen untersucht und deren Alter mit Radiokarbon- sowie Lumineszenzdatierungen bestimmt. Daneben wurden auch archäologische Daten und historische Karten genutzt, um die Altersstellung der einzelnen Terrassen einzugrenzen. Im Untersuchungsgebiet bildet eine spätglaziale Niederterrasse die älteste Flussterrasse innerhalb des Talbodens, die allerdings nur im Donautal unterhalb der Lechmündung erhalten ist. In beiden Tälern sind präboreale bis boreale Terrassenflächen nur kleinräumig verbreitet, während ein Sockelschotter gleichen Alters weiträumig unter jüngeren Ablagerungen anzutreffen ist. Atlantische Flussbettablagerungen sind im Untersuchungsgebiet nicht zu finden. Dagegen dominieren subboreale und subatlantische Terrassen das Lechmündungsgebiet. Die heutigen Flussläufe von Lech und Donau werden von bis zu sechs subatlantischen Terrassen begleitet. Deren Verbreitung und morphologisches Erscheinungsbild verweist im Donautal oberhalb der Lechmündung auf einen mäandrierenden Flusslauf, die der jüngsten Lechterrasse auf ein verzweigtes Gerinnebettmuster. Unterhalb der Lechmündung treten dagegen Übergangsformen beider Flussgrundrisstypen auf.

    Description: In Petäjäselka (Nord-Finnland) wurde ein geschichtetes Sedimentpaket mit einer zwischengeschalteten Organiklage nachgewiesen, welches in Till der Grundmoräne eingebettet war. Die Grundmoräne hatte eine Mächtigkeit von 3 m und wurde von einem Moor überlagert. Durch Rammkernbohrungen war dann eine 1–15 cm mächtige Organiklage nachweisbar, die in Tiefen von 5.5–6.0 m jeweils in Sanden eingebettet war. Der organische Horizont ist durch eine Pinus-Betula-Gemeinschaft und ein absolutes Alter von 35,300 ± 600 BP (14C) gekennzeichnet. Die unterlagernden Sande wurden an zwei Lokalitäten per OSL auf Alter von 72.6 ± 21.3 ka und 58.1 ± 17.0 ka datiert. Für den überlagernden Sand wurde per OSL an einer der Lokalitäten ein Alter von 31.8 ± 5.6 ka bestimmt. Den Datierungsergebnissen zufolge repräsentieren die in den Till eingebetten Sande mit dem Organikhorizont ein Interstadial des Mittel-Weichsel. Desweiteren lässt sich daraus für Nord-Finnland eine eisfreie Phase während des Mittel-Weichsels im Zentrum des Skandinavischen Eisschildes ableiten.

    Description: Der vorliegende Artikel gibt einen Überblick über neu datierte Abschnitte in bekannten Löss/Paläoboden-Sequenzen Niederösterreichs. Die Ergebnisse der Datierungen im Profil Joching deuten darauf hin, dass es im letzten Hochglazial zur Lösssedimentation kam. Die meisten erfassten Alter sind jedoch älter als das letzte Hochglazial, was auf Erosionsprozesse hindeutet, die zur Abtragung der jüngeren Lösse geführt hat. In dem Abschnitt zwischen ~28 ka and ~35 ka wurden überwiegend Tundragleye gebildet. Eine intensivere interstadiale Bodenbildung ist nicht nachzuweisen. Dieses Ergebnis kann auch für die stratigraphische Einstufung von ‚Stillfried B‘ (sensu Fink) von Bedeutung sein. Der folgende chronologische Abschnitt liegt zwischen ~35 ka and ~57 ka in Lösssedimenten mit eingeschalteten Tundragleyen. Auch dieser Abschnitt ist durch Umlagerungsprozesse charakterisiert. Im Zeitraum von ~57 ka bis ~106 ka befindet sich eine markante Zeitlücke, die vermutlich auf langandauernde und intensive Erosionsprozesse im Untersuchungsgebiet zurückzuführen ist. Die älteste Datierung in den Sedimenten des letzten Glazials mit 106 ± 12 ka befindet sich in Paudorf direkt über dem ‚Stillfried A‘- Komplex (Paudorfer Bodenbildung). Direkt unter diesem Pedokomplex, bzw. vergleichbaren Pedokomplexen treten in Lössablagerungen Alter von 124 ± 2 5 ka (Göttweig-Aigen), 159 ± 20 ka (Paudorf 1), and 170 ± 16 ka (Joching) auf. Darüber hinausgehende Alter konnten in Stratzing, Paudorf 2, Göttweig-Furth und Langenlois nachgewiesen werden.

    Description: Geoarchäologische Untersuchungen im Bereich eines glazigenen Solls verweisen auf den holozänen menschlichen Einfluss auf einer Grundmoränenplatte in Vorpommern in prähistorischer und historischer Zeit sowie dessen geomorphologische Rückkopplung. Die basale sedimentäre Füllung der untersuchten Depression besteht aus Torf, Mudde und Verlandungstorf und spiegelt früh- bis mittelholozäne hydrologische Schwankungen wider. Die obere Sequenz von wechselnden Kolluvien und organogenen Schichten deutet auf einen variierenden menschlichen Einfluss im Laufe der Zeit hin. Absolute AMS 14C-Datierungen von begrabenen Torfen und Mineralbodenhorizonten mit zum Teil erhöhten Anteilen organischer Substanz, abgesichert durch palynologische und archäologische Daten, belegen zwischenzeitliche Phasen von Oberflächenstabilität. Hingegen reflektieren die kolluvialen Sande Phasen erhöhter prähistorischer und historischer Besiedlung und Landnutzung. Die Sande können zum einen relativ durch die organogenen Schichten datiert und zum anderen zu den benachbarten archäologischen Funden in Beziehung gebracht werden. Erhöhte Erosionsprozesse werden demnach in das späte Neolithikum, den Übergang späte Bronzezeit zur frühen Eisenzeit, das Mittelalter und letztendlich in die Moderne gestellt. Die Akkumulation des jüngsten Kolluviums führt im Randbereich des Solls zur völligen Verfüllung bis an die rezente Oberfläche.

    Description: Eine Übersicht der aktuellen stratigraphischen Bezeichnungen für die quartäre Schichtenfolge Südbayerns wird gegeben, wie sie am Geologischen Dienst des Bayerischen Landesamts für Umwelt in Verwendung ist. Unterschiedliche stratigraphische Gliederungsansätze für kontinentale Quartärablagerungen werden vorgestellt und die klimatostratigraphische Einteilung sowie die Terrassenstratigraphie als in Bayern meistverwendete Varianten näher ausgeführt. Die Beschreibung der zugehörigen, bisher informellen Einheiten bezweckt eine Dokumentation des jeweiligen Stands der Verwendung und kann womöglich formelle Definitionen vorbereiten. Die klimatostratigraphischen Einheiten sollen den gesamten Zeitraum des Quartärs lückenlos abdecken und vertreten derzeit Überregionale, formelle Stufenbezeichnungen. In Bayern wird weiterhin die klassische Gliederung nach Penck & Brückner (1901–1909) mit ihren Erweiterungen verwendet. Neue Erkenntnisse über eine stärkere Gliederung des Eiszeitalters durch untergeordnete Kalt- und Warmphasen werden in dieses System integriert. Für diese Gliederung des Quartärs in Südbayern ausschlaggebend sind zum Einen die Terrassentreppen, deren zeitliche Interpretation eine Grundlage der sogenannten Morphostratigraphie bildet. Die zweite Grundlage bilden Endmoränengirlanden, die mit den davon ausgehenden Terrassen glazial-glazifluviale Sequenzen (‚Glaziale Serien’) bilden. Neben der ausführlichen Dokumentation der Terrassen-Einheiten, werden deshalb auch verschiedene Endmoränen-Gliederungen vorgestellt. Weitere Nomenklaturen, die auf anderen Kriterien beruhen oder zu anderen chronologischen Einstufungen gelangen, sind für Bayern oder in den angrenzenden Ländern in Gebrauch. Auch die beschriebenen stratigraphischen Gliederungen werden nicht von allen Bearbeitern in gleicher Weise verwendet. Die Dokumentation der derzeitigen Verwendung soll eine Abstimmung dieser Nomenklaturen im Interesse der Nutzer fördern.

    Description: Es wird ein Überblick über die in Österreich verwendete Quartär-Stratigraphie gegeben. Die stratigraphische Gliederung der kartierbaren Sedimenteinheiten basiert teilweise auf Kriterien der Lithostratigraphie (lithologischer Eigenschaften) und jenen der Allostratigraphie (z.B. Diskonitinuitäten). Für das Altpleistozän (2.58–0.78 Ma) fehlen bis jetzt Spuren einer Vergletscherung. Die wenigen und isolierten Sedimentvorkommen belegen fluviatile Akkumulation und Lössablagerung in der Umgebung der Flüsse. Paläomagnetisch korrelierte Löss-Paläoboden – Sequenzen wie das Profil Stranzendorf mit der Gauss/Matuyama – Grenze bzw. Neogen/Quartär – Grenze dokumentieren in Übereinstimmung mit den globalen δ18O Werten etwas wärmere Bedingungen als im Mittelpleistozän (0.78–0.13 Ma). Vier Großvergletscherungen (Günz, Mindel, Riß und Würm) sind für Mittelpleistozän und Jungpleistozän belegt. Diese sind mit Sedimenten aus der Vorstoßphase überlagert von Grundmoräne, Endmoränen im Alpenvorland und damit verknüpfte Terrassenschüttungen sowie Lössakkumulation dokumentiert. Daraus ist die klimagesteuerte Sedimentation im Zusammenhang mit dem Vorstoß der Gletscher, der Ausbreitung des Permafrostes und der Frostschuttbildung bis ins Vorland erkennbar. Die jüngsten Großvergletscherungen Riß und Würm werden aufgrund geochronologischer Daten mit den Marinen Isotopenstufen (MIS) 6 und 2 korreliert. Für Günz und Mindel scheint eine Gleichzeitigkeit mit den Phasen massiver globaler Klimaverschlechterung während MIS 16 und MIS 12 plausibel. Dokumente für die schwächeren Glaziale wurden bisher nur in Lössprofilen (z.B. Krems Schießstätte) gefunden.

    Description: Anhand zweier Profile aus dem Niederrheingebiet wird die Komplexität der Genese und Chronologie letztinterglazialer bis früh-weichselzeitlicher Löss-Paläoboden-Sequenzen diskutiert. Die untersuchten Profile wurden in den Braunkohletagebauen Inden und Garzweiler aufgenommen und sind mit mittelpaläolithischen Fundkomplexen verknüpft. Erstmalig werden dabei Multi-Element-Analysen neben Lumineszenz-Datierungen an Quarzen (ITL, OSL) aus niederrheinischen Lössprofilen vorgestellt und diskutiert. Die Ergebnisse offenbaren große Unsicherheiten hinsichtlich einer stratigraphischen und paläoklimatischen Interpretation von polygenetisch uüberprägten Sediment- und Paläobodensequenzen. Eine bedeutende Rolle nimmt dabei auch die Reliefposition in Verbindung mit der Morphogenese des Paläoreliefs ein, die in höherem Maße als bisher berücksichtigt werden sollte.

    Description: Während der letzten ~100 ka Glazial-Interglazial-Zyklen war die Konzentration des Treibhausgases CO2 in der Atmosphäre eng mit der globalen Temperatur gekoppelt. Die Gründe fuür die CO2 Konzentrationsschwankungen wurden bislang vor allem im Ozean vermutet, bleiben aber rätselhaft. Darüberhinaus gibt es nur spekulative Erklärungsansätze für den mittelpleistozänen Übergang von den 41 ka Eiszeitzyklen im Frühpleistozän vor ~0.7 Ma zu den ~100 ka Eiszeitzyklen danach. Die klassische Milankovitch Theorie der Sommerinsolation in hohen nördlichen Breiten kann die Abfolge der pleistozänen Eiszeiten nicht vollständig erklären. Basierend auf jüngsten Erkenntnissen, dass die Menge des organischen Bodenkohlenstoffs in Permafrostgebieten massiv unterschätzt wurde, und der simplen Logik, dass Permafrostgebiete und die entsprechende Kohlenstoffspeicherung in den Eiszeiten vermutlich wesentlich größer waren als in den Warmzeiten, soll hier eine „Permafrost Hypothese“ vorgestellt werden: (i) Langsame Anreicherung von Kohlenstoff in Permafrostböden während Abkühlungsphasen, sowie rasche Freisetzung von CO2 und Methan während Erwärmungsphasen, sind entscheidende positive Rückkopplungsprozesse für das Klima. (ii) Änderungen der integrierten annuellen Insolation an der südlichen, und damit sensitiven Permafrostgrenze könnten als externe Auslöser für globale Klimaveränderungen fungieren. (iii) Der mittelpleistozäne Wechsel der Eiszeitzyklen könnte implizit damit erklärt werden, dass Permafrostgebiete im Laufe der langfristigen pleistozänen Abkühlung Breiten von ~45°N erreichten. Dort verschwindet das für höhere nördliche Breiten charakteristische aus der Schiefe der Ekliptik resultierende ~41 ka Signal der annuellen Insolation, und es dominiert allein das ~100 ka Signal der orbitalen Ekzentrizität.

    Description: Die Kenntnis der regionalen Paläohydrologie ist eine wesentliche Grundlage für das Verständnis aktueller Umweltfragen, wie zum Beispiel nach den Gründen von hydrologischen Veränderungen, dem Einfluss von Landnutzungsstrategien und der Wirksamkeit von Renaturierungsvorhaben in Feuchtgebieten. Auch die Interpretation von Modellierungsergebnissen zu den künftigen Einflüssen des Klima- und Landnutzungswandels auf das Gewässersystem kann durch die Einbeziehung (prä-) historischer Analogien verbessert werden. Für das glazial geprägte nordostdeutsche Tiefland wurde eine Übersicht der vorliegenden paläohydrologischen Befunde für den Zeitraum der letzten etwa 20.000 Jahre erarbeitet. Die Entwicklung der Flüsse wurde mit Blick auf die Tal-/Auengenese und das Ablagerungsmilieu, die Veränderung des Tal- und Gerinneverlaufs sowie den Paläoabfluss bzw. das Paläohochwasser betrachtet. Wesentliche genetische Unterschiede bestehen zwischen Alt- (Elster- und Saalekaltzeit) und Jungmoränengebieten (Weichselkaltzeit) sowie zwischen hoch und tief gelegenen Tälern. Letztere sind stark durch Wasserspiegelveränderungen in der Nord- und Ostsee beeinflusst worden. Die Entwicklung der Seen wurde hinsichtlich der Seebildung, die überwiegend eine Folge der spätpleistozänen bis frühholozänen Toteistieftau-Dynamik ist, und der Veränderungen im Ablagerungsmilieu analysiert. Weiterhin standen Seespiegelveränderungen im Fokus, wobei sich hoch variable lokale Befunde mit einigen Übereinstimmungen zeigten. Der Überblick zur Moorentwicklung konzentrierte sich auf hydrogenetische Moorentwicklungsphasen und auf die langfristige Entwicklung des Grundwasserspiegels. Enge Beziehungen zwischen der Entwicklung der Flüsse, Seen und Moore bestanden insbesondere im Spätholozän durch komplexe Vermoorungsprozesse in den großen Flusstälern. Bis in das Spätholozän wurde die regionale Hydrologie überwiegend durch klimatische, geomorphologische und nicht-anthropogene biologische Faktoren gesteuert. Seit dem Spätmittelalter wurde in der Region das Gewässernetz und der Wasserkreislauf im starken Maß durch anthropogene Interventionen beeinflusst (z.B. Aufstau von Flüssen und Seen, Bau von Kanälen und Deichen, Moorkultivierung). In den letzten etwa 50 Jahren haben dann sogar die kurzfristigen anthropogenen Eingriffe, z.B. in Form von Abflussregulierung, Hydromelioration und künstlicher Seebildung, die Wirksamkeit langfristiger klimatischer und geomorphologischer Prozesse übertroffen.

    Description: Eine revidierte Vergletscherungsgeschichte des nördlichen Vorlandes der Schweizer Alpen wird vorgestellt, basierend auf Feldbefunden und chronologischen Daten von verschiedenen Schlüssellokalitäten und Regionen. Die ältesten quartären Sedimente der Schweiz sind mehrphasige Kiese, in die Till und Hochflutsedimente eingeschaltet sind (’Deckenschotter’). Bedeutende Unterschiede im Basisniveau der Schotterablagerungen erlauben die Unterscheidung zweier komplex augebauter Einheiten (’Höhere Deckenschotter’, ’Tiefere Deckenschotter’), die durch eine Phase bedeutender Einschneidung getrennt sind. Säugetierreste stellen die ältere Einheit (‘Höhere Deckenschotter’) in die Zone MN 17 (2.6–1.8 Ma). Jeder der Komplexe enthält Belege für zumindest zwei, möglicherweise sogar bis zu vier eigenständige Eiszeiten, woraus sich in Summe bis zu acht frühpleistozäne Vergletscherungen des Schweizer Alpenvorlands ergeben. Die frühpleistozänen Deckenschotter sind von mittelpleistozänen Ablagerungen durch eine Zeit bedeutender Erosion getrennt, die wahrscheinlich durch tektonische Bewegungen und/oder eine Umleitung des Alpenrheins verursacht wurde (Mittelpleistozäne Reorganisation – MPR). Das Mittel-/Spätpleistozän beinhaltet vier oder fünf Eiszeiten, die nach ihren Schlüsselregionen als Möhlin-, Habsburg-, Hagenholz- (unsicher, unzureichend belegt), Beringen- und Birrfeld-Eiszeit benannt sind. Die Möhlin-Eiszeit repräsentiert die grösste Vergletscherung des Schweizer Alpenvorlandes, während die Beringen-Eiszeit von nur wenig geringerer Ausdehnung war. Der letzte Glazialzyklus (Birrfeld-Eiszeit) umfasst wahrscheinlich drei eigenständige Gletschervorstösse, die auf ca. 105 ka, 65 ka und 25 ka datiert wurden. Für den letzten Eisvorstoss wird eine detaillierte Radiokohlenstoffchronologie für den Eisaufbau und das Abschmelzen präsentiert.
