Description: Salinity and trace mineral accumulation threaten the sustainability of crop production in many semi-arid parts of the world, including California’s western San Joaquin Valley (WSJV). We used data from a multi-year field-scale trial in Kings County and related container trials to simulate a forage-grazing system under saline conditions. The model uses rainfall and irrigation water amounts, irrigation water quality, soil, plant, and atmospheric variables to predict Bermuda grass (Cynodon dactylon (L.) Pers.) growth, quality, and use by cattle. Simulations based on field measurements and a related container study indicate that although soil chemical composition is affected by irrigation water quality, irrigation timing and frequency can be used to mitigate salt and trace mineral accumulation. Bermuda grass yields of up to 12 Mg dry matter (DM)·ha−1 were observed at the field site and predicted by the model. Forage yield and quality supports un-supplemented cattle stocking rates of 1.0 to 1.2 animal units (AU)·ha−1. However, a balance must be achieved between stocking rate, desired average daily gain, accumulation of salts in the soil profile, and potential pollution of ground water from drainage and leaching. Using available weather data, crop-specific parameter values and field scale measurements of soil salinity and nitrogen levels, the model can be used by farmers growing forages on saline soils elsewhere, to sustain forage and livestock production under similarly marginal conditions.

Description: In form and in content, cities are the epitome of diversity. This state is the result of the accumulation of layers of history, of construction, of demolition and reconstruction cycles. These tensions are the catalyst for the emergence of new urban forms and participate in the construction of heritage. As such they should be encouraged. As important as the existing fabric of the city is, its evolution to accommodate the ever-changing needs and fashions of its inhabitants is paramount. For regeneration to be successful it must inscribe itself in this process and it must be driven by an understanding of the environment where it occurs. This paper explores, through the lens of an architectural practice, some design processes and architectural proposals that have been generated by working on the Valletta harbours. It also discusses the necessary dynamics required to accommodate stakeholder engagement and planning policy while ensuring design quality and the perpetuation of the creative process inherent to the city. Finally, the paper introduces, as a possible future, the experiments and studies of the practice on the wider Valletta, putting into perspective the benefits of theoretical research combined with formal and aesthetic explorations of the harbour region.

Description: Migrant remittances are increasingly seen as a potential form of development in the global South, but the impact of international migration on sending regions is far from straightforward. In this article, I analyze migrant communities of origin in rural Bolivia as dynamic places that are constantly reproduced through connections with other places. I document the movement of migrant practices between Washington D.C. and Cochabamba and the influence of monetary and non-monetary flows on Bolivian cultural practices, politics, and development. I demonstrate how hometown associations and returning migrants have transferred organizational practices and political ideas about development from the United States to rural Bolivia. In addition, I explore migration’s role in struggles over belonging in Cochabamba, focusing on the efforts by migrants in Washington D.C. to stake their claim through transnational houses and collective remittance projects and on recent internal migration from other regions in Bolivia. Finally, I assess the sustainability of migrant-led development in Cochabamba. Although collaboration with migrants can strengthen the local state by providing more resources, it conditions the type of development that can take place and has yet to provide adequate opportunities for returning migrants or young people in rural Bolivia.

Description: Discussions on how to define, design, and implement sustainable development goals (SDG) have taken center stage in the United Nations since the Rio+20 summit. Energy is one of the issues that enjoyed consensus, before and after Rio, as an important area for SDGs to address. Many proposals have been put forward on how SDGs should be formulated and what areas they should cover, but there have been few attempts to develop a generic integrated framework within which diverse areas can be accommodated and treated in a coherent way. The purpose of this paper is to develop such a framework for SDGs and to demonstrate its application by elaborating specific target areas for the energy sector. Based on a review and integration of global debates around SDG and energy, the framework puts human wellbeing at the center of the agenda, with the supporting resource base and global public goods forming additional tiers. A complementary set of enabling goals is suggested with four layers: capacity & knowledge, governance & institutions, public policy, and investment & finance. An energy SDG is elaborated to illustrate the application of the framework. The illustrative SDG architecture for energy includes eight target areas: basic energy access, energy for economic development, sufficiency, renewable supply, efficiency, infrastructure, greenhouse gas emissions and security. These target areas are relevant for energy for all countries, but depending on national circumstances such as levels of development, the relative emphasis will be different between countries, and over time.

Description: A survey of wastewater treatment facilities in the Federated States of Micronesia revealed a lack of fully functional treatment systems and conditions that potentially could lead to adverse environmental impacts and public health concerns. Due to inadequate facilities, the amount and composition of wastewater entering the plants as well as the degree of treatment being achieved is largely unknown. In some cases raw sewage is being discharged directly into the ocean and waste sludge is regularly taken by local residents for agricultural purposes without adequate treatment. In addition, the need to establish best management practices for placement and maintenance of septic tanks is urgent. Furthermore, development of eco-friendly solutions is needed to more effectively treat wastewater from industrial and agricultural sources in an effort to abate current pollution problems. Comparisons of treatment methods being used and problems encountered at different locations in the islands would provide valuable information to aid in the development of sustainable treatment practices throughout Micronesia.

Description: The purpose of this study was to examine the role and visibility of disabled people in the discourses of various global policy processes related to sustainable development and the Post-2015 development agenda. This article makes several recommendations for strengthening the role of disabled people in these discourses. The research addresses the question of how the disability community and sustainable development community relate to each other in these discourses. This study provides quantitative and qualitative data on three aspects of the relationship. One set of data highlights who is seen as a stakeholder in general and the visibility of disabled people in the social sustainability, sustainable consumption, Rio+20 and Post-2015 development agenda proposals discourses and what participants of the online consultation for a disability inclusive development agenda towards 2015 and beyond had to say about the issues of visibility of disabled people in development discourses. A second set of data illuminates the attitudes towards disabled people evident in the SD discourses including through the eyes of the participant of the online consultation for a disability inclusive development agenda towards 2015 and beyond. The final set of data compares the goals and actions seen as desirable for the advancement of SD evident in the SD literature covered and the online consultation for a disability inclusive development agenda towards 2015 and beyond. This study interpreted the data through a disability studies lens. The study found that disabled people were barely visible to invisible in the SD literature covered, that the goals and actions proposed in the SD discourses are of high relevance to disabled people but that these discussions have generally not been explicitly linked to disabled people. It found further that disabled people have clear ideas why they are invisible, what the problems with development policies are and what needs to happen to rectify the problems. It found also that there was a lack of visibility of various SD areas and goals within the disability discourse. This paper provides empirical data that can be used to further the goal of mainstreaming of disabled people into the SD and Post-2015 development discourses as asked for in various high-level UN documents. However, we posit that the utility of our paper goes beyond the disability angle. Our quantitative data also highlights other forms of social group visibility unevenness in the literature and as such, we argue that the data we present in this paper is also of use for other stakeholders such as youth, women and indigenous people and also for NGOs and policy makers.

Description: This study presents a unique way by which a university program can contribute to capacity development for coastal sustainability. The program is steered by a working group of volunteer faculty members, having different academic backgrounds, in collaboration with students and marine professionals, including fisherfolk and environment education interpreters. Although the program began with conventional educational ideas and style, its practical framework evolved to include interactive activities with collaborators in the community, all of which were geared toward social learning. The combination of service learning and participatory action research (PAR) was proven to be an adequate approach to link higher education for sustainable development (HESD) and university-community partnerships and to promote learning for coastal sustainability. Challenges identified include (1) ensuring continuity of learning and (2) reducing the heavy workload of faculty members involved in program preparation and coordination. The authors would like to emphasize the possibilities offered by the engagement of scholarship in the capacity development for coastal sustainability by focusing on community-based efforts.

Description: A field experiment was performed in Southwest Germany to examine the effects of long-term reduced tillage (2000–2012). Tillage treatments were deep moldboard plow: DP, 25 cm; double-layer plow; DLP, 15 + 10 cm, shallow moldboard plow: SP, 15 cm and chisel plow: CP, 15 cm, each of them with or without preceding stubble tillage. The mean yields of a typical eight-year crop rotation were 22% lower with CP compared to DP, and 3% lower with SP and DLP. Stubble tillage increased yields by 11% across all treatments. Soil nutrients were high with all tillage strategies and amounted for 34–57 mg kg−1 P and 48–113 mg kg−1 K (0–60 cm soil depth). Humus budgets showed a high carbon input via crops but this was not reflected in the actual Corg content of the soil. Corg decreased as soil depth increased from 13.7 g kg−1 (0–20 cm) to 4.3 g kg−1 (40–60 cm) across all treatments. After 12 years of experiment, SP and CP resulted in significantly higher Corg content in 0–20 cm soil depth, compared to DP and DLP. Stubble tillage had no significant effect on Corg. Stubble tillage combined with reduced primary tillage can sustain yield levels without compromising beneficial effects from reduced tillage on Corg and available nutrient content.

Description: This paper examines the efficiency of electro-oxidation used as the single pretreatment of landfill leachate. The experiments were performed on three different types of leachate. The results obtained using this electrochemical method results were analyzed after seven days of treatment. The main characteristics of leachate and a diagram of the experimental apparatus are presented. The overall objectives were to contribute to the knowledge of electrochemical treatments for the reduction of COD, BOD5, ammonium, and total suspended solids, and also to examine whether there was any resulting hexavalent chromium in the liquid sample. The yields obtained were considered satisfactory, particularly given the simplicity of this technology. Like all processes used to treat refluent water, the applicability of this technique to a specific industrial refluent needs to be supported by feasibility studies to estimate its effectiveness and optimize the project parameters. This could be a future development of the work.

Description: Italian harbours assume a decisive role in order to develop a Euro-Mediterranean web for maritime transportation. The geostrategic position of the Italian peninsula can be seen as a logistic platform at the centre of the maritime trades in the Mediterranean area, giving to its port cities the role of gateway of economic flows. The port poles, meant as hubs, are able to attract investments and create economic growth and territorial development through new operative models of urban usage and management. The management policies have to consider the environmental characteristics and distinctive features, respecting the identity of the places as concrete evidence of history, a source of intellectual development and therefore, cultural richness. In this sense, the current strategic plan “Palermo capital of the Euro-Mediterranean area” imagines the whole city, and not just its harbour, as a “gate city”, a sustainable and cosmopolitan city in the view of a recentralization of the Mediterranean area. The research tests an evaluation method in support of urban planning, which increases the active role of stakeholders in terms of participation and access to the decision-making process of urban renewal strategies for Palermo to the Euro-Mediterranean.

Description: The zero-sum nature of mega-event hosting encourages cities to escalate investment with an eye towards convincing event rights holders that a positive outcome will result. The discursive frameworks of “legacy” and “sustainability”, the global competition to attract events and the compressed event horizon make for mega-event preparation regimes that may seriously compromise long-term urban planning agendas in mega-event hosts. By examining the sustainable urban planning literature, the discursive frameworks of sustainability in the International Olympic Committee (IOC) and the discursive framing of the Rio 2016 bid, this paper will examine the Olympic Golf project being implemented in Rio de Janeiro. Through this case study the paper argues that unless mega-event rights holders change their candidacy and selection processes, these events will inevitably be detrimental to their hosts.

Description: The aim of this paper is to assess the strength and weakness factors of post-industrial cities located in the Gulf of Naples in order to propose the most effective regeneration strategies towards a sustainable development of the urban coastline. This paper focuses on the city of Torre Annunziata and in particular on its industrial port area and waterfront. The analysis suggests that a sustainable development would be possible through the redesign and new functionalization of the waterfront and port area, improving resilience and creativity in order to integrate economic growth, ecological preservation and social opportunities. Thus, this paper is a proposal for a participative approach to the regeneration of the urban waterfront, enhancing the creative potential of the city and developing a new image for the waterfront that could become the strategic vision for a future economic, environmental and cultural development. A comparison between the waterfronts of Torre Annunziata and La Spezia has been carried out in order to assess what are the most effective choices for the future of Torre Annunziata, followed by an applicative process based on interviews.

Description: The paper describes the shifting perspective from the contemplative view to the dynamic-evolutionary view of heritage and the main characteristics of the resulting multi-criterial decision-aid tool for the evaluation of heritage. With the integration of conservation in planning processes and with opening of the procedures to public participation, there is a need for decision-aid tools that can help increase rationality and transparency in decision-making processes related to planning. By understanding the contemporary view of heritage and the landscape, it is possible to create tools capable of accounting for spatial complexity and the extant cultural, social, historic and economic relations. With this in mind, a specific tool was created that can be used for the analysis, diagnosis, evaluation and monitoring of spatial heritage (registered and under consideration for protection), identifying opportunities, defining strategies for heritage management processes, and in the creation and evaluation of development and management scenarios. The paper illustrates a shift in the consideration of heritage in spatial planning and presents an application of the developed model in a case study.

Description: Cities are traditionally considered as centers of prosperity, but after a long process of deindustrialization, the classical opportunities presented by cities as administrative, production, financial and cultural hot spots can no longer be taken for granted without questioning the present organizational and spatial models. After an introduction to the decision-aid tools and processes needed to orient development in a sustainable way, the paper describes the characteristics and an application of the decision-aid tool created for analysis, diagnosis and evaluation of opportunities. The proposal briefly considers the reconnection of the city with its region, urban renewal, creative and productive activities, necessary support institutions, contemporary sustainable economic approaches and infrastructure. This approach is illustrated on the case of the incubator proposal for the City of Rijeka, Croatia, once an important port and industrial city with a long history. The technological modifications in the functioning of the port and abandoning of industrial production in the proximity, but also geological formation and prevalent building typologies, make the case exemplary of the problems faced in contemporary cities. The paper proposes a process and tools for analysis and evaluation and indicators for the sustainability of the proposal.

Description: Sustainability science seeks to identify and implement workable solutions to complex problems. This transdisciplinary approach advances a commitment to work across boundaries that occur among individuals, disciplines, and institutions to build capacities for informed and innovative decision making in the face of uncertainty and change. The concept of boundary work and related discussions of boundary objects and organizations are important, expanding focal areas within sustainability science. While communication is described as central to boundary work, insights from the field of communication have largely yet to inform theorizing about boundaries within sustainability science. In this paper, we highlight three communication perspectives, namely media studies, collaboration and partnerships, and systems theories, which are particularly relevant for understanding how boundaries form, the social context in which boundary work occurs, and informed strategies for enhanced boundary spanning and management. We use three case studies to illustrate how communication theories and methods provide dynamic and strategic lenses within transdisciplinary processes to enable collaborators to build capacity for change, sustain critical and reflective inquiry, and approach difference as generative in collective efforts to produce sustainability.

Description: This study performs a comparison between the theoretical frameworks of sustainable development and its incorporation in the decision-making practices and models used by heavy construction companies. This study was conducted by using documentary analysis of corporate sustainability reports. Specifically, the content analysis method was used to examine the sustainability reports disclosed by the companies studied. The results indicate four main conclusions: first, the social, political and economic context directed the companies towards implementing sustainable management practices; second, human resource development follows the traditional model of training and development; third, there is an evident effort to balance economic goals and profit-making with social responsibility practices as a way to characterize the corporate commitment with sustainability; fourth, effective and indispensable measures to transform decision-making models were not adopted in the business practices analyzed, and thus the economic factor continues to be prioritized at the expense of social and environmental aspects in those models. This paper, in looking at three Brazilian multinational heavy construction companies, examines the synergy between the theoretical and the identified corporate sustainability practices. Lastly, this paper may be characterized as a descriptive study based on a literature review and an analysis of sustainability reports from the companies studied.

Description: Urban renovation projects, which have led to the conversion of port areas through a new vision of waterfronts as elements of the potential development of the urban system in its entirety, have spread since the early 1950s and now some port cities are able to trigger some mechanisms which, even if they are the result of some processes that have been activated for decades and which are still evolving, are able to amplify and to extend over time their generated positive impacts. These impacts also produce a system of relations in the context of the hinterland, attracted also by policies of economic, social, and cultural development. In the case of the city of Valencia, we have seen, in the last 50 years, a progressive spread of the urbanized area to the coasts, simultaneously with a process of renovation of the port area, which has been populated by important architectures, and which has been equipped by efficient infrastructures and subjected to numerous recovery and restoration operations of its historic buildings. However, the environmental conditions near the port area are not well suited to a good quality of life because ports are pollution producers, sites of urban decay, and of social degradation. A good plan can include some instruments to decrease those negative factors, leading to a close merging between the port area and the city hinterland, and generating new economies. The proposal of this research consists in a method of integrating the port planning with an environmental accounting system.

Description: The aim of this paper is to highlight some perspectives for the sustainable development of Naples, to direct future policies for the city. The proposed approach is based on the Historic Urban Landscape, which, being structurally integrated/systemic, allows the relationship between the historic center and the waterfront, as well as many contradictions, to be overcome, which in the city of Naples, have become particularly acute. The notion of Historic Urban Landscape (HUL) is the latest contribution to the international debate concerning the identification, preservation and valorization of cultural heritage. This new category, in fact, refers to the notion of context to emphasize the systemic interrelation between economic, social, environmental and cultural factors and the complexity of the framework within which conservation policies are inserted. It is in this perspective that the experiences of planning taking place in Naples are read, as a starting point for an innovative approach to the issue of an integrated conservation of the Historic Urban Landscape and, more generally, of the regeneration of the city. The starting point is the study of the experiences of urban transformation in some European port cities in order to “learn from comparison” to develop a theoretic approach based on the understanding of reality. The comparative analysis of case studies, through the synthesis of the most significant aspects of each port city, allows the relationship that exists between a phenomenon and its context to be understood and the critical success factors to be identified, in order to transfer the knowledge gained from good practices in the processes of regeneration of the city of Naples. Naples, for its stratified urban fabric, rich in tangible and intangible cultural values, and for its particular nodal position within the Mediterranean basin, lends itself effectively to a different approach to urban regeneration, which focuses on the relationship between the historic city and the sea.

Description: After the 2008 crisis, smart sustainable development of port areas/cities should be developed on the basis of specific principles: the synergy principle (between different actors/systems, in particular the socio-cultural and economic system), the creativity principle and the circularization principle. The Historic Urban landscape (HUL) approach becomes the guarantee that the transition toward the smart city development model is based on specific local cultural resources, and not only on technological innovations. In other words, the eco-town/eco-city strategy becomes culture-led. It stimulates places as spatial “loci” for implementing synergies and circularization processes. Without new evaluation tools and a widespread “evaluation culture” the risks in implementing HUL are very high.

Description: Source separation is a common method for dealing with the increasing problem of Municipal Solid Waste (MSW) in society. The citizens are then responsible for separating waste fractions produced in their home. If the consumers fail to sort the waste according to the source separation scheme, it will lead to an ineffective system. The purpose of this paper is to analyze the environmental, economic and social aspects of incorrect waste sorting in a medium sized Swedish city that has established a source separation system. In order to determine the extent to which citizens correctly sort their waste, food waste (black bags) and combustible fraction (white bags), were collected randomly from a residential area and categorized in different waste fractions. The results show that approximately 68 wt% of the waste in the white and 29 wt% in the black bags were not sorted correctly. This incorrect sorting accrues over 13 million SEK per year cost for this community. In order to improve the inhabitants’ participation in the waste management system, it is necessary to change different factors such as convenience and easy access to the recycling stations in the local MSW management systems as well as to review current regulation and policy.

Description: Much attention is now focused on utilizing ground heat pumps for heating and cooling buildings, as well as water heating, refrigeration and other thermal tasks. Modeling such systems is important for understanding, designing and optimizing their performance and characteristics. Several heat transfer models exist for ground heat exchangers. In this review article, challenges of modelling heat transfer in vertical heat exchangers are described, some analytical and numerical models are reviewed and compared, recent related developments are described and the importance of modelling these systems is discussed from a variety of aspects, such as sustainability of geothermal systems or their potential impacts on the ecosystems nearby.

Description: This paper analyzes the effect of systems to manage environmental aspects on environmental performance at individual polluting facilities. Regulated polluting facilities are increasingly embracing pollution minimization strategies that involve the adoption of broadly defined systems to manage environmental aspects. Despite a meaningful empirical literature, whether or not these systems lead to better environmental performance remains an open question. This study seeks to assess the possible connection between systems to manage environmental aspects and improved environmental performance. It also seeks to identify the factors determining the extent of the adopted system of management and the factors’ direct effects on environmental performance. For this empirical analysis, the study examines the extent of systems to manage environmental aspects employed by and the level of wastewater discharged by U.S. chemical manufacturing facilities during 2001.

Description: Is “diversity” a modern concept, like indigeneity or biodiversity, which is conceived precisely at the time that it seems to be threatened and on the verge of disappearing? In the face of perceived threats to diversity, projects and policies have been crafted to protect, promote, or conserve diversity, but in doing so they have often demonstrated a paradoxical propensity toward purity and authority in representations of diversity. Perceptions of “pure” natural diversity might represent native forests comprised solely of native species; “pure” cultural diversity might represent indigenous peoples who still speak indigenous languages and wear native dress. If purity is emblematic of diversity, what, then, is the place of hybrid landscapes and peoples? In our study, we draw on a range of examples—of agrobiodiversity conservation in Bolivia, satellite mapping initiatives in Madagascar and Ecuador, scientific authority about anthropogenic climate change, indigenous language and identity in Peru, and a comparison of the Amazon and Atlantic Forest in Brazil—to demonstrate gaps between representations of diversity, and the heterogeneous local realities they obscure. We suggest that hybridity is a form of diversity unto itself—albeit a form of diversity that is more complex, and thus harder to codify and categorize.

Description: A bioeconomy can be defined as an economy where the basic building blocks for materials, chemicals and energy are derived from renewable biological resources. This paper provides an overview of the bioeconomy in Europe, examining it from a policy framework and concept perspective. The role of bioenergy in the bioeconomy is discussed particularly through biofuels for transport and biorefineries. The study finds that the definitions of the bioeconomy are evolving and vary depending on the actor, but display similarities such as the emphasis on economic output and a broad, cross-sectoral focus. While there is great optimism about the benefits and opportunities associated with developing an advanced bioeconomy in Europe, significant risks and trade-offs are also expressed. Furthermore, the bioeconomy concept has been criticised for presenting a technical fix and pre-empting alternative visions. To advance a competitive and sustainable bioeconomy, this paper calls for attention on two important themes: participatory governance that engages the general public and key stakeholders in an open and informed dialogue as well as a commitment by government and industry to innovation that drives concerted efforts on sustainable development of the bioeconomy.

Description: One of primary challenges for ensuring effective and efficient functions of the multilateral nuclear approaches (MNA) to nuclear fuel cycle facilities is harmonization between a MNA framework and existing nuclear cooperation agreements (NCA). A method to achieve such harmonization is to construct a MNA framework with robust non-proliferation characteristics, in order to obtain supplier states’, especially the US’s prior consents for non-supplier states’ certain activities including spent fuel reprocessing, plutonium storages and retransfers of plutonium originated in NCAs. Such robust characteristics can be accomplished by MNA member states’ compliances with International Atomic Energy Agency (IAEA) Safeguards, regional safeguards agreements, international conventions, guidelines and recommendations on nuclear non-proliferation, nuclear security, safety, and export control. Those provisions are to be incorporated into an MNA founding agreement, as requirements to be MNA members in relation to NCAs. Furthermore, if an MNA facility is, (1) owned and operated jointly by all MNA member states, (2) able to conclude bilateral NCAs with non-MNA/supplier states as a single legal entity representing its all member states like an international organization, and (3) able to obtain necessary prior consents, stable, smooth, and timely supplies of nuclear fuel and services can be assured among MNA member states. In this paper, the authors will set out a general MNA framework and then apply it to a specific example of Europe Atomic Energy Community (EURATOM) and then consider its applicability to the Asian region, where an establishment of an MNA framework is expected to be explored.

Description: There is a concern that agriculture will no longer be able to meet, on a global scale, the growing demand for food. Facing such a challenge requires new patterns of thinking in the context of complexity and sustainability sciences. This paper, focused on the social dimension of the study and management of agricultural systems, suggests that rethinking the study of agricultural systems entails analyzing them as complex socio-ecological systems, as well as considering the differing thinking patterns of diverse stakeholders. The intersubjective nature of knowledge, as studied by different philosophical schools, needs to be better integrated into the study and management of agricultural systems than it is done so far, forcing us to accept that there are no simplistic solutions, and to seek a better understanding of the social dimension of agriculture. Different agriculture related problems require different policy and institutional approaches. Finally, the intersubjective nature of knowledge asks for the visualization of different framings and the power relations taking place in the decision-making process. Rethinking management of agricultural systems implies that policy making should be shaped by different principles: learning, flexibility, adaptation, scale-matching, participation, diversity enhancement and precaution hold the promise to significantly improve current standard management procedures.

Description: “Sustainable” is among the most sought after of all seafood product adjectives. Ironically it is also one of the most poorly defined and understood. The Global Aquaculture Performance Index (GAPI) is the first tool to assess environmental performance of global marine aquaculture production, permitting direct comparison of disparate species, production methods and jurisdictions. Clear patterns emerge from this analysis; significant variation of environmental performance is driven by the species being farmed, significant room for improvement exists across the entire sector, the worst performing players are also the fastest growing, particularly within Asia, and perhaps most importantly, this work highlights the potential trap awaiting policy makers who focus too narrowly on farm production efficiency alone as a solution to diminishing seafood availability.

Description: The high prevalence of food insecurity experienced by northern First Nations partially results from dependence on an expensive import-based food system that typically lacks nutritional quality and further displaces traditional food systems. In the present study, the feasibility of import substitution by Agroforestry Community Gardens (AFCGs) as socio-ecologically and culturally sustainable means of enhancing food security was explored through a case study of Fort Albany First Nation in subarctic Ontario, Canada. Agroforestry is a diverse tree-crop agricultural system that has enhanced food security in the tropics and subtropics. Study sites were selected for long-term agroforestry research to compare Salix spp. (willow)-dominated AFCG plots to a “no tree” control plot in Fort Albany. Initial soil and vegetative analysis revealed a high capacity for all sites to support mixed produce with noted modifications, as well as potential competitive and beneficial willow-crop interactions. It is anticipated that inclusion of willow trees will enhance the long-term productive capacity of the AFCG test plots. As an adaptable and dynamic system, AFCGs have potential to act as a more reliable local agrarian system and a refuge for culturally significant plants in high-latitude First Nation socio-ecological systems, which are particularly vulnerable to rapid cultural, climatic, and ecological change.

Description: The purpose of this paper is to point out some of the main characteristics and critical factors for success that can substantiate the proposal of a differentiation framework for maritime clusters. We conduct a benchmarking analysis intended to distinguish the most relevant aspects which can or should be observed in these types of clusters, applied to the following countries: Spain (Basque Country), Germany (Lander of Schleswig-Holstein), the Netherlands and Norway. The differentiation factors involve agglomeration economies and endogenous conditions derived from geographic proximity, essential for lowering transaction costs, strengthening the leverage of public/private cooperation through centres of maritime excellence, at the same time providing an adequate local environment that favours positive interactions between the different maritime industries and actors. The main results arising from this article are presented through a reconceptualisation of Porter’s Diamond framework for diagnosing the competitiveness of maritime clusters.

Description: From a holistic view, this paper addresses a perspective of coordinated development of economy, society, and environment for regional sustainability assessment. Firstly, a comprehensive indicator system for co-evaluating the level of economic, social, and environmental subsystems is presented based on a holistic understanding of regional sustainability. Then, a coordinated development index model focusing on the level of coordination among the subsystems as well as their comprehensive development level is established. Furthermore, an empirical study of all the provinces and municipalities is conducted by collecting the panel data from 2004 to 2010. The result shows that: (1) the coordinated developments of the most developed and the most underdeveloped regions stay stable while the regions with medium development level possess more fluctuant trends during the study years; (2) regional disparities are indicated according to the grading of CDI (the coordinated development index), which are further analyzed to be related to the local economic development patterns; (3) the conditions and causes of economic, social, and environmental development in real situations under different grades of CDI are discussed through detailed case studies of typical regions, which indicate specific suggestions of sustainable development for regions in the same pattern.

Description: As the largest solid waste (SW) generator in the world, China is facing serious pollution issues induced by increasing quantities of SW. The sustainability assessment of SW management is very important for designing relevant policy for further improving the overall efficiency of solid waste management (SWM). By focusing on industrial solid waste (ISW) and municipal solid waste (MSW), the paper investigated the sustainability performance of SWM by applying decoupling analysis, and further identified the main drivers of SW change in China by adopting Logarithmic Mean Divisia Index (LMDI) model. The results indicate that China has made a great achievement in SWM which was specifically expressed as the increase of ISW utilized amount and harmless disposal ratio of MSW, decrease of industrial solid waste discharged (ISWD), and absolute decoupling of ISWD from economic growth as well. However, China has a long way to go to achieve the goal of sustainable management of SW. The weak decoupling, even expansive negative decoupling of ISW generation and MSW disposal suggests that China needs timely technology innovation and rational institutional arrangement to reduce SW intensity from the source and promote classification and recycling. The factors of investment efficiency and technology are the main determinants of the decrease in SW, inversely, economic growth has increased SW discharge. The effects of investment intensity showed a volatile trend over time but eventually decreased SW discharged. Moreover, the factors of population and industrial structure slightly increased SW.

Description: Terra Preta Sanitation (TPS) plays a key role in sustainable sanitation (SuSan) and in the sustainable management of resources such as water, energy, soil (agriculture), liquid and solid organic waste streams as well as in the development of sustainable urban environment and infrastructure systems. This paper discusses the advantages of, and requirements for, SuSan systems, focusing on TPS. Case studies showing the stepwise extension and re-development of conventional sanitation systems (CSS) using TPS technologies and system approaches are presented and discussed. Decentralized TPS systems integrated in sustainable urban resource management were implemented in the German cities of Hamburg and Berlin. The compilation of best practice examples and findings using the newest TPS systems illustrates the immense potential of this approach for the transformation from conventional to SuSan systems. For this purpose, the potential savings of drinking water resources and the recycling potential of nutrient components are quantified. The results strongly suggest the need to encourage the development and application of innovative decentralized sanitation technologies, urban infrastructures, and resource management systems that have TP as a key component.

Description: Native chilies (Capsicum spp.) are currently underutilized in Bolivia, one of this crop’s centers of diversity. Fewer local farmers cultivate native chilies annually due to low market demand. Increasing its private use value can lead to the in-situ conservation of this crop. The objective of the paper is to evaluate the market acceptability of three native chili products: (a) chili marmalade; (b) chili cooking paste; and (c) pickled chilies. Multi-product Becker-DeGroot-Marschak experimental auctions and hedonic tests were conducted with 337 participants in La Paz and Santa Cruz. Data were analyzed using seemingly unrelated regressions. Results suggest that consumers are willing to pay price premiums of about 25–50 percent. Biodiversity conservation and improvements in farmers’ quality of life statements would not have influence on first purchase decisions but rather on repurchase decisions and therefore on consumers’ product loyalty. This in turn could lead to sustainable agro-biodiversity conservation, centered on consumers’ purchase of these products over time.

Description: This study proposes a new concept, green organisational ambidexterity, that integrates green exploration learning and green exploitation learning simultaneously. Besides, this study argues that the antecedents of green organisational ambidexterity are green shared vision and green absorptive capacity and its consequents are green radical innovation performance and green incremental innovation performance. The results demonstrate that green exploration learning partially mediates the positive relationships between green radical innovation performance and its two antecedents—green shared vision and green absorptive capacity. In addition, this study indicates that green exploitation learning partially mediates the positive relationships between green incremental innovation performance and its two antecedents—green shared vision and green absorptive capacity. Hence, firms have to increase their green shared vision, green absorptive capacity, and green organisational ambidexterity to raise their green radical innovation performance and green incremental innovation performance.

Description: The South Korean government has long been attempting to reduce the nation’s heavy reliance on fossil fuels and increase environmental safety by developing and installing renewable power generation infrastructures and implementing policies for promoting the green growth of Korea’s energy industry. This study focuses on the use of independent renewable power generation systems in the more than 3000 officially affirmed islands off Korea’s coast and proposes a simulated solution to the electricity load demand on Ulleungdo Island that incorporates several energy sources (including solar, batteries, and wind) as well as one hydro-electric and two diesel generators. Recommendations based on the simulation results and the limitations of the study are discussed.

Description: Evaluation of the sustainability of biomass pyrolysis requires a thorough assessment of the product yields and energy densities. With this purpose, a laboratory scale fixed bed reactor (FBR) was adapted from the standard Gray-King (GK) assay test on coal to conduct fixed bed pyrolysis experiments on agricultural and agro-industrial by-products. The present study provides results on the pyrolysis of two types of biomass: chipped olive tree trimmings (OT) and olive pomace (OP). Solid (char) and liquid (tar) product yields are reported. Mass yields are determined and compared with values obtained in similar works. Results indicate that char yield decreases from 49% (OT-db) and 50% (OP-db) at 325 °C to 26% (OT db) and 30% (OP-db) at 650 °C. Tar yield is almost constant (42%) at different reaction temperatures for OT, while it decreases slightly from 42% to 35% for OP. Energy density of the products at different peak temperatures is almost constant for OT (1.2), but slightly increases for OP (from a value of 1.3 to a value of 1.4).

Description: Efficient delivery and precision provision of urban public services concern quality of urban life and urban sustainability. Amid much debate regarding citizen assessments as a policy tool of public services, this study examines the validity of citizen assessments through user assessments of urban green spaces (UGSs) in Guangzhou, China. Users can distinguish the qualities of UGS across the dimensions and types, the assessment of individual UGSs matches the overall assessment of all UGSs in the city as a whole, and the overall assessment is only slightly influenced by personal backgrounds. Findings consistently support user assessments as a policy tool of UGSs and offer empirical evidence on the validity of citizen assessments. This positive evidence will encourage city managers to seriously consider citizen assessments and even institutionalize them as a standard management practice of (specific) urban public services, including UGSs, in China and abroad.

Description: The aim of this study is to analyze the environmental performance of countries and the variables that can influence it. At the same time, we performed a multivariate analysis using the HJ-biplot, an exploratory method that looks for hidden patterns in the data, obtained from the usual singular value decomposition (SVD) of the data matrix, to contextualize the countries grouped by geographical areas and the variables relating to environmental indicators included in the environmental performance index. The sample used comprises 149 countries of different geographic areas. The findings obtained from the empirical analysis emphasize that socioeconomic factors, such as economic wealth and education, as well as institutional factors represented by the style of public administration, in particular control of corruption, are determinant factors of environmental performance in the countries analyzed. In contrast, no effect on environmental performance was found for factors relating to the internal characteristics of a country or political factors.

Description: The relationship between economic growth, expansion of urban land area and the broader issue of cultivated land conversion in China has been closely examined for the late 1980s and 1990s. Much less is known about recent urban expansion and if the effects of economic growth on this expansion have changed over time. This paper updates estimates of urban expansion for China and examines the relationship with city economic growth for 1993–2012. To see if patterns are robust to different types of evidence, administrative data on the area of 225 urban cores are compared to estimates of brightly lit areas from remotely sensed night lights. The trend annual expansion rate in lit area is 8% and was significantly faster in the decade to 2002 than in the most recent decade. Expansion is slower according to administrative data, at just 5% per annum, with no change in unconditional expansion rates between decades, while conditional expansion rates have declined. The elasticity of area with respect to city economic output is about 0.3. Over time, expansion of urban land area is becoming less responsive to the growth of the local non-agricultural population.

Description: In this study a microclimate analysis on a particular urban configuration: the—street canyon—has been carried out. The analysis, conducted by performing numerical simulations using the finite volumes commercial code ANSYS-Fluent, shows the flow field in an urban environment, taking into account three different aspect ratios (H/W). This analysis can be helpful in the study on urban microclimate and on the heat exchanges with the buildings. Fluid-dynamic fields on vertical planes within the canyon, have been evaluated. The results show the importance of the geometrical configuration, in relation to the ratio between the height (H) of the buildings and the width (W) of the road. This is a very important subject from the point of view of “Smart Cities”, considering the urban canyon as a subsystem of a larger one (the city), which is affected by climate changes.

Description: This paper analyzes the differences in the amount and the structure of residential energy consumption at the provincial level in China and identifies the hidden factors behind such differences. The econometrical analysis reveals that population, economic development level, energy resource endowment and climatic conditions are the main factors driving residential energy consumption; while the regional differences in energy consumption per capita and the consumption structure can be mainly illustrated by various economic development levels, energy resource endowments and climatic conditions. Economic development level has a significant positive impact on the proportion of gasoline consumption, whereas its impact on the proportion of electricity consumption is not notable; energy resource endowment and climatic condition indirectly affect both the proportion of electricity consumption and that of gasoline consumption, primarily through their impacts on the proportions of coal consumption and heat consumption.

Description: Urbanization transforms urban-rural landscape and profoundly affects ecological processes. To maintain a sustainable urbanization, two important issues of land-use need to be quantified: the comprehensive variation of urban-rural construction land and the specific models for consolidating these lands. The purpose of this study is to develop a framework to assess the change of urban-rural construction land and build a decision-support system for consolidating these lands. Four sub-layers were first built in the assessment framework, including the characteristic layer, the coordination layer, the potential layer and the urgency layer. Each layer encompassed specific indices for evaluating the change of urban-rural construction land in different aspects. The entropy method was then applied to the data resources from Landsat TM (Thematic Mapper) images, statistical data and overall land-use and land consolidation planning of Nantong city in coastal China to allocate weightings to the indices in each sub-layer. Finally, the decision-support system was built based on the assessment results and the degree of importance for consolidating urban and rural construction land, respectively. The results of our study show an overall investigation and quantitative description of the change of urban-rural construction land and provide an effective framework for land consolidation and land use management.

Description: The identification and characterization of particulate matter (PM) concentrations from construction site activities pose major challenges due to the diverse characteristics related to different aspects, such as concentration, particle size and particle composition. Moreover, the characterization of particulate matter is influenced by meteorological conditions, including temperature, humidity, rainfall and wind speed. This paper is part of a broader investigation that aims to develop a methodology for assessing the environmental impacts caused by the PM emissions that arise from construction activities. The objective of this paper is to identify and characterize the PM emissions on a construction site with different aerodynamic diameters (PM2.5, PM10, total suspended particulates (TSP)), based on an exploratory study. Initially, a protocol was developed to standardize the construction site selection criteria, laboratory procedures, field sample collection and laboratory analysis. This protocol was applied on a multifamily residential building construction site during three different construction phases (earthworks, superstructure and finishings) aimed at measuring and monitoring PM concentrations arising from construction activities. The particulate matter was characterized in different particle sizes. Results showed that the higher TSP emissions arising from construction activities provoked environmental impacts. Some limitations to the results were identified, especially with regards the need for a detailed investigation about the influence of different construction phases on PM emissions. The findings provided significant knowledge about various situations, serving as a basis for improving the existing methodology for particulate material collection on construction sites and the development of future studies on the specific construction site phases.

Description: With a unique cultural background and fast economic development, China’s adoption of corporate social responsibility (CSR) has become the center of discussion worldwide, and its successful implementation will have great significance for global sustainability. This paper aims to explore how CSR has given way to economic growth in China since the start of economic transition and its cultural, historical and political background, and how this has affected or been affected by the economic performance of firms. Thus, the recent calls for China to adopt CSR in its industries follow a period where the country arguably had one of the strongest implementations of CSR approaches in the world. This transition is considered in the context of a case study of a Chinese state-owned enterprise (SOE) and a group of small private firms in the same industrial sector in Zhengzhou City, Henan Province over a time span of eight years. While the CSR of the SOE has been steadily decreasing along with the change of ownership structure, its economic performance did not improve as expected. On the other hand, with a steady improvement in economic performance, the small private firms are showing a great reluctance to engage in CSR. The results indicate that implementation of CSR in China needs both the manager’s ethical awareness and the change of institutional framework. The results also raise the question as to whether CSR is a universal concept with a desired means of implementation across the developed and developing world.

Description: Interdisciplinary sustainability science teamwork skills are essential for addressing the world’s most pressing and complex sustainability problems, which inherently have social, natural, and engineering science dimensions. Further, because sustainability science problems exist at global scales, interdisciplinary science teams will need to consist of international members who communicate and work together effectively. Students trained in international interdisciplinary science skills will be able to hit the ground running when they obtain jobs requiring them to tackle sustainability problems. While many universities now have sustainability science programs, few offer courses that are interdisciplinary and international in scope. In the fall semester of 2013, we piloted a course for graduate students entitled “Principles of Interdisciplinary Sustainability Research” at Michigan Technological University. This course was part of our United States National Science Foundation Partnerships in International Research and Education project on bioenergy development impacts across the Americas. In this case study, we describe the course development and implementation, share critical insights from our experience teaching the course and student learning outcomes, and give recommendations for future similar courses.

Description: In most emerging economies, there has been many incentives and high availability of funding for low-cost housing projects. This has encouraged product standardization and the application of mass production ideas, based on the assumption that this is the most effective strategy for reducing costs. However, the delivery of highly standardized housing units to customers with different needs, without considering their lifestyle and perception of value, often results in inadequate products. Mass customization has been pointed out as an effective strategy to improve value generation in low-cost housing projects, and to avoid waste caused by renovations done in dwellings soon after occupancy. However, one of the main challenges for the implementation of mass customization is the definition of a set of relevant options based on users’ perceived value. The aim of this paper is to propose a method for defining value adding attributes in customized housing projects, which can support decision-making in product development. The means-end chain theory was used as theoretical framework to connect product attributes and costumers’ values, through the application of the laddering technique. The method was tested in two house-building projects delivered by a company from Brazil. The main contribution of this method is to indicate the customization units that are most important for users along with the explanation of why those units are the most relevant ones.

Description: A fiber optic daylighting system is an evolving technology for transporting illumination from sunlight into building interiors. This system is a solution developed by daylighting designers to reduce operational costs and enhance comfort. As an innovative technology, fiber optic daylighting systems can illuminate building interiors efficiently compared with other daylighting strategies. However, as a transmission medium in daylighting systems, optical fibers require uniform light distribution in sunlight concentration, which could generate heat. Therefore, this study aims to investigate the effect of heat buildup produced by end-emitting fiber optic daylighting systems in tropical buildings. The applied method adopts a new fiber optic daylighting system technology from Sweden called Parans SP3, with a 10 m cable to be tested in an actual room size under the Malaysian climatic environment, particularly within the vicinity of the main campus of the Universiti Sains Malaysia. Results show that the system generated a temperature of 1.3 °C under average conditions through fiber optic diffusers and increases indoor temperature by 0.8 °C in a 60 m3 room. According to the results, applying fiber optic daylighting systems, as renewable energy sources, generates extra heat gain in building interiors in the tropics.

Description: Coastal fisheries contribute to global food security, since fish are an important source of protein for many coastal communities in the world. However, they are constrained by problems, such as weak management of fisheries and overfishing. Local communities perceive that they are fishing less, as in other fisheries in the world. The aim of this study was to evaluate the fisheries sustainability in the Jalisco coast through the fishing footprint, or fishprint (FP), based on the primary productivity required (PPR) and the appropriated surface by the activity (biocapacity). The total catch was 20,448.2 metric tons from 2002–2012, and the average footprint was calculated to be 65,458 gha/year, a figure that quadrupled in a period of 10 years; the biocapacity decreased, and the average trophic level of catches was 3.1, which implies that it has remained at average levels, resulting in a positive balance between biocapacity and ecological footprint. Therefore, under this approach, the fishing activity is sustainable along the coast of Jalisco.

Description: Modern biotechnology, including the application of transgenic techniques to produce Genetically Modified Organisms (GMOs), can play a significant role in increasing agricultural production in a sustainable way, but its products need to be tailored for the developing world. In sub-Saharan Africa, the capacity to develop GMOs and ensure they meet stringent regulatory requirements is somewhat limited. Most African governments contribute little to science and technology either financially or through strong policies. This leaves the determination of research and development priorities in the hands of international funding agencies. Whereas funding from the United States is generally supportive of GM technology, the opposite is true of funding from European sources. African countries are thus pulled in two different directions. One alternative to this dilemma might be for countries in the sub-Saharan Africa region to develop stronger South-South collaborations, but these need to be supported with adequate funding. African governments as well as external funding agencies are urged to consider the important role that biotechnology, including GM technology, can play in contributing to sustainable development in Africa, and to provide adequate support to the development of capacity to research, develop and commercialize GMOs in the region.

Description: The Peruvian anchovy fishery is the largest worldwide in terms of catches. The fishery started during the mid 1950s, and since then it has been highly dependent on natural stock fluctuations, due to the sensitivity of anchovy stocks to ocean-climate variability. The main driver of anchovy stock variability is the El Niño Southern Oscillation (ENSO), and three extreme ENSO warm events were recorded in 1972–1973, 1983–1984 and 1997–1998. This study investigates the evolution of coping strategies developed by the anchovy fisheries to deal with climate variability and extreme ENSO events. Results showed eight coping strategies to reduce impacts on the fishery. These included: decentralized installation of anchovy processing factories; simultaneous ownership of fishing fleet and processing factories; use of low-cost unloading facilities; opportunistic utilization of invading fish populations; low cost intensive monitoring; rapid flexible management; reduction of fishmeal price uncertainty through controlled production based on market demand; and decoupling of fishmeal prices from those of other protein-rich feed substitutes like soybean. This research shows that there are concrete lessons to be learned from successful adaptations to cope with climate change-related extreme climatic events that impact the supply of natural resources. The lessons can contribute to improved policies for coping with climate change in the commercial fishery sector.

Description: Unconferencing is a method for organizing social learning which could be suitable to trigger sustainability learning processes. An unconference is defined as participant-driven meeting that tries to avoid one or more aspects of a conventional conference, such as top-down organization, one-way communication and power-relationships based on titles, formal hierarchies and status. This paper presents a case study on the application of unconferencing in a large Swiss university (ETH Zurich) where an unconference was conducted to engage students, academics, staff and external experts in a mutual learning process aimed at the development of project ideas for reducing its CO2 emissions. The study analyzes how the unconferencing format initiated and promoted sustainability oriented group processes during the unconference, and in how far the projects which were developed contributed to a reduction of the university’s CO2 emissions.

Description: Understanding the socio-economic factors that are associated with fishers’ willingness to delay gratification may be useful for designing appropriate fisheries management and conservation policies. We aim to identify the predictors of low discounting behaviour among fishers, which is analogous to having a longer-term outlook. We base our empirical study on two small-scale tropical reef fisheries in Sabah, Malaysia, and Fiji. We use an experimental approach to identify fishers with low discount rates, and then use a logistic regression model to identify predictors of low discount rates. We find that 42% of the respondents have low discount rates, and that site and village level variables are significant predictors of low discount rates. Within Sabah and Fiji, boat ownership and relative catch differentiate low discounting from non-low discounting fishers, but these variables have contradictory effects in Sabah and Fiji. Overall, our results imply that a substantial proportion of reef fishers may be willing to engage in conservation initiatives; however, local socio-cultural, economic, and ecological conditions have to be considered first during the process of designing management interventions.

Description: This paper explores the politics around the role of agency in the UK climate change debate. Government interventions on the demand side of consumption have increasingly involved attempts to obtain greater traction with the values, attitudes and beliefs of citizens in relation to climate change and also in terms of influencing consumer behaviour at an individual level. With figures showing that approximately 40% of the UK’s carbon emissions are attributable to household and transport behaviour, policy initiatives have progressively focused on the facilitation of “sustainable behaviours”. Evidence suggests however, that mobilisation of pro-environmental attitudes in addressing the perceived “value-action gap” has so far had limited success. Research in this field suggests that there is a more significant and nuanced “gap” between context and behaviour; a relationship that perhaps provides a more adroit reflection of reasons why people do not necessarily react in the way that policy-makers anticipate. Tracing the development of the UK Government’s behaviour change agenda over the last decade, we posit that a core reason for the limitations of this programme relates to an excessively narrow focus on the individual. This has served to obscure some of the wider political and economic aspects of the debate in favour of a more simplified discussion. The second part of the paper reports findings from a series of focus groups exploring some of the wider political views that people hold around household energy habits, purchase and use of domestic appliances, and transport behaviour-and discusses these insights in relation to the literature on the agenda’s apparent limitations. The paper concludes by considering whether the aims of the Big Society approach (recently established by the UK’s Coalition Government) hold the potential to engage more directly with some of these issues or whether they merely constitute a “repackaging” of the individualism agenda.

Description: The development of genetically engineered (GE) crops has focused predominantly on enhancing conventional pest control approaches. Scientific assessments show that these GE crops generally deliver significant economic and some environmental benefits over their conventional crop alternatives. However, emerging evidence indicates that current GE crops will not foster sustainable cropping systems unless the negative environmental and social feedback effects are properly addressed. Moreover, GE crop innovations that promote more sustainable agricultural systems will receive underinvestment by seed and chemical companies that must understandably focus on private returns for major crops. Opportunities to promote crops that convey multi-faceted benefits for the environment and the poor are foundational to a sustainable food system and should not be neglected because they also represent global public goods. In this paper, we develop a set of criteria that can guide the development of GE crops consistent with contemporary sustainable agriculture theory and practice. Based on those principles, we offer policy options and recommendations for reforming public and private R&D and commercialization processes to further the potential contributions of GE crops to sustainable agriculture. Two strategies that would help achieve this goal would be to restore the centrality of the public sector in agricultural R&D and to open the technology development process to more democratic participation by farmers and other stakeholders.

Description: Negligence of former industrial sites (“brownfields”) has adversely impacted urban landscapes throughout the industrialized world. Brownfield redevelopment has recently emerged as a sustainable land use strategy and impetus for urban revitalization. This study presents a system dynamics model of the redevelopment process that illustrates how delays compound before realizing financial benefits from investment in these core urban areas. We construct a dynamic hypothesis, in which brownfield redevelopment activities are dependent upon funding and in turn bolster tax base through job creation. Drawing on previous studies, barriers to brownfield redevelopment are explored, including fear of liability, regulatory concerns, and uncertain cleanup standards and funding mechanisms. We model a case study of redevelopment in the State of Michigan (USA), which is informed by data from the Department of Environmental Quality (MDEQ) and U.S. Conference of Mayors brownfield surveys. Stock-flow structures represent phases of redevelopment, with diverted streams for sites in which no contamination was found (false alarms) and those with excess contamination level. The model is used to examine the point at which cumulative tax revenues from redeveloped areas exceed cumulative expenditures on brownfield redevelopment under different levels of funding availability.

Description: This paper analyzed the characteristic of the tourism destination ecosystem from perspective of entropy in Dunhuang City. Given these circumstances, an evaluation index system that considers the potential of sustainable development was formed based on dissipative structure and entropy change for the tourism destination ecosystem. The sustainable development potential evaluation model for tourism destination ecosystem was built up based on information entropy. Then, we analyzed each indicator impact for the sustainable development potential and proposed some measures for the tourism destination ecosystem. The conclusions include: (a) the requirements of Dunhuang tourism destination ecosystem on the natural ecosystem continuously grew between 2000 and 2012; (b) The sustainable development potential of the Dunhuang tourism destination ecosystem was on an oscillation upward trend during the study period, which is dependent on government attention, and pollution problems were improved.

Description: Exploring the relationship between different services has become the focus of ecosystem services research in recent years. The agro-ecosystem, which accounts for one-third of the global land area, provides lots of services but also disservices, depending on resources provided by other systems. In this paper, we explored the agro-ecosystem from four aspects: a summary of different indicators in the agro-ecosystem, input and output changes with time, relationships between different ecosystem services and disservices, and resource contribution to major services, using Luancheng County of North China as the study area. We then used emergy analysis to unify all the indicators. The conclusions were that the agro-ecosystem maintained provisioning and regulating services but with increasing volatility under continued growth in production inputs and disservice outputs. There was a positive correlation between most of the different services and disservices. Rainfall and groundwater resources were the most used input resources in the agro-ecosystem and all other major ecosystem services depended directly on them.

Description: Integrated analysis on socio-economic metabolism could provide a basis for understanding and optimizing regional sustainability. The paper conducted socio-economic metabolism analysis by means of the emergy accounting method coupled with data envelopment analysis and decomposition analysis techniques to assess the sustainability of Qingyang city and its eight sub-region system, as well as to identify the major driving factors of performance change during 2000–2007, to serve as the basis for future policy scenarios. The results indicate that Qingyang greatly depended on non-renewable emergy flows and feedback (purchased) emergy flows, except the two sub-regions, named Huanxian and Huachi, which highly depended on renewable emergy flow. Zhenyuan, Huanxian and Qingcheng were identified as being relatively emergy efficient, and the other five sub-regions have potential to reduce natural resource inputs and waste output to achieve the goal of efficiency. The results of decomposition analysis show that the economic growth, as well as the increased emergy yield ratio and population not accompanied by a sufficient increase of resource utilization efficiency are the main drivers of the unsustainable economic model in Qingyang and call for polices to promote the efficiency of resource utilization and to optimize natural resource use.

Description: In recent years, there has been an increase in the types of marine weapons used in response to diverse hostile threats. However, because marine weapons are only tested under a single set of environmental conditions, failures due to different environmental stresses have been difficult to detect. Hence, this study proposes an environmental test sequence for multi-environment testing. The environmental test sequences for electrical units described in the international standard IEC 60068-1, and for military supply described in the United States national standard MIL-STD-810G were investigated to propose guidelines for the appropriate test sequences. This study demonstrated the need for tests in multiple environments by investigating marine weapon accidents, and evaluated which environmental stresses and test items have the largest impacts on marine weapons using a two-phase quality function deployment (QFD) analysis of operational scenarios, environmental stresses, and environmental test items. Integer programming was used to determine the most influential test items and the shortest environmental test time, allowing us to propose optimal test procedures. Based on our analysis, we developed optimal environmental test sequences that could be selected by a test designer.

Description: A widespread dissemination of improved cooking stoves in the developing world can lead to considerable improvement of health, to reduced pressure on natural woody resources and to substantial reductions of emissions contributing to global warming. A number of programs have aimed to achieve such dissemination, while few of the programs have had any large-scale success. It has been suggested that a more commercial approach, as opposed to subsidized or freely distributed stoves, would achieve a higher level of success. However, a majority of the households that would benefit from an improved stove are poor and cannot afford the cost of the stove, especially if no monetary savings are possible from a more efficient fuel use, i.e., if the fuel used is collected biomass. The aim of this paper is to propose and evaluate a model that might overcome some of the barriers previous programs have experienced. The proposed model involves commercialization of collected fuels. The methods for evaluation include a qualitative assessment of the proposed model aided by the literature on improved cooking stove programs, fuel wood collection and fuel switching together with a quantitative simplistic model calculation of a hypothetical application of the proposed model principles, in order to assess its financial feasibility. The assessment indicates that the model would increase both households’ incentives and means to purchase and use improved cooking stoves. Furthermore, the model could possibly be partly financed based on carbon credits achieved from the reduction of greenhouse gas emissions.

Description: This paper investigates the state of food security in Romania and its place in the world. We analysed the level of food security indicators for 1990–2012, in Romania, and their average levels worldwide. References are also made to developed and developing countries. The research seeks to answer the questions: Is food security achieved in Romania and, if so, what kind of structural changes can be made towards improving food quality and people’s living standards? As indicators show, the findings indicate that food security is ensured, on average, in Romania. Dietary energy supply is above dietary energy requirements, the ratio of cereals import dependency is below its average level worldwide, and the daily diet is balanced between vegetal and animal origin food. Having solved the quantitative aspect of food security, Romania can look towards improving the qualitative aspects of it. In this regard, organic food may be considered as a direction of developing sustainable agricultural economy.

Description: To achieve agricultural sustainability, basic land planning would allocate more areas for specific land uses with high ecosystem service values. However, this has always failed because of its low economic interest. Paying farmers would be effective for its implementation. To overcome previous studies’ limitation in spatial display, we developed a novel approach with a spatially explicit land use plan under payment policy. It integrates the tradeoff analysis into a traditional land use optimal allocation system. The land allocation system generates an origin land use scenario. Our method analyzes farmers’ tradeoffs in changing crops by adopting payment policy. Finally, the origin land use map is reallocated. The newly reclaimed region of Yili, China is studied as a representative area. Our tool established a tradeoff curve indicating the adoption proportion of farmers changing other land use types to clover, which is a specific crop with high ecosystem service values, at different payment prices. Areas adopting the payment policy were identified, and corresponding spatial distribution maps of land use re-allocation were generated for the tradeoff curve. Sensitivity analysis validated the robustness of our model. Results demonstrated that our method can provide more spatial and economic information for sustainable land use planning.

Description: The need for integrated methodological framework for sustainability assessment has been widely discussed and is urgent due to increasingly complex environmental system problems. These problems have impacts on ecosystems and human well-being which represent a threat to economic performance of countries and corporations. Integrated assessment crosses issues; spans spatial and temporal scales; looks forward and backward; and incorporates multi-stakeholder inputs. This study aims to develop an integrated methodology by capitalizing the complementary strengths of different methods used by industrial ecologists and biophysical economists. The computational methodology proposed here is systems perspective, integrative, and holistic approach for sustainability assessment which attempts to link basic science and technology to policy formulation. The framework adopts life cycle thinking methods—LCA, LCC, and SLCA; stakeholders analysis supported by multi-criteria decision analysis (MCDA); and dynamic system modelling. Following Pareto principle, the critical sustainability criteria, indicators and metrics (i.e., hotspots) can be identified and further modelled using system dynamics or agent based modelling and improved by data envelopment analysis (DEA) and sustainability network theory (SNT). The framework is being applied to development of biofuel supply chain networks. The framework can provide new ways of integrating knowledge across the divides between social and natural sciences as well as between critical and problem-solving research.

Description: The purpose of the paper is two-fold. First, to identify the main sustainability issues that Scottish food supply chain actors are concerned with and any differences that exist between primary producers, processors and distributors and consumers; and second, to explore the implications of respondents’ views for the direction of food and drink policy in Scotland. The analysis was based on a dataset assembled from the written responses to the National Food Policy discussion in Scotland, which contains opinions on the different dimensions of sustainability (economic, environmental and social) from a broad range of individuals and organizations representing different segments of the Scottish population. The empirical analyses involved comparing the responses according to two criteria: by food supply chain stakeholder and by geographical region. The results indicated that whilst there were differences among the studied groups, the importance of social and economic sustainability were strongly evident in the foregoing analysis, highlighting issues such as diet and nutrition, the importance of local food, building sustainability on sound economic performance, the market power of supermarkets, and regulation and support in building human and technical capabilities.

Description: Recently increasing attention has been paid to complementing environmental Life Cycle Assessment (LCA) with social aspects. The paper discusses the selection of social impacts and indicators from existing frameworks like Social Life Cycle Assessment (SLCA) and Social Impact Assessment (SIA). Two ongoing case studies, addressing sustainability assessment within decision support, were considered: (1) Integrated Water Resources Management (IWRM) in Indonesia; and (2) Integrated Packaging Waste Management in Spain and Portugal (FENIX). The focus was put on social impacts occurring due to decisions within these systems, such as choice of technologies, practices or suppliers. Thus, decision makers—here understood as intended users of the studies’ results—are not consumers that buy (or do not buy) a product, such as in recent SLCA case-studies, but mainly institutions that decide about the design of the water or packaging waste management system. Therefore, in the FENIX project, a list of social impacts identified from literature was sent to the intended users to be ranked according to their priorities. Finally, the paper discusses to what extent the entire life cycle is reflected in SLCA impact categories and indicators, and explains how both life-cycle and on-site-related social impacts were chosen to be assessed. However, not all indicators in the two projects will assess all stages of the life cycle, because of their varying relevance in the different stages, data availability and practical interest of decision makers.

Description: The paper is based on findings from research that assesses the potential for enhancing the performance of compressed earth bricks. A set of experiments was carried out to assess the potential for enhancing the bricks’ physical, mechanical and hygrothermal performance through the design of an optimal stabilization strategy. Three different types of bricks were fabricated: soil-cement, soil-cement-lime, and soil-cement-fiber. The different types of bricks did not exhibit significant differences in performances when assessed on the basis of porosity, density, water absorption, and compressive strength. However, upon exposure to elevated moisture and temperature conditions, the soil-cement-fiber bricks had the highest residual strength (87%). The soil-cement and soil-cement-lime bricks had residual strength values of 48.19 and 46.20% respectively. These results suggest that, like any other cement-based material, compressed earth brick properties are affected by hydration-triggered chemical and structural changes occurring in the matrix that would be difficult to isolate using tests that focus on “bulk” changes. The discussion in this paper presents findings from a research effort directed at quantifying the specific changes through an analysis of the microstructure.

Description: World population is projected to reach its maximum (~10 billion people) by the year 2050. This 45% increase of the current world population (approaching seven billion people) will boost the demand for food and raw materials. However, we live in a historical moment when supply of phosphate, water, and oil are at their peaks. Modern agriculture is fundamentally based on varieties bred for high performance under high input systems (fertilizers, water, oil, pesticides), which generally do not perform well under low-input situations. We propose a shift of research goals and plant breeding objectives from high-performance agriculture at high-energy input to those with an improved rationalization between yield and energy input. Crop breeding programs that are more focused on nutrient economy and local environmental fitness will help reduce energy demands for crop production while still providing adequate amounts of high quality food as global resources decline and population is projected to increase.

Description: This is a review of the literature available on data for the EROI (prior to this special issue) of the following 12 sources of fuel/energy: oil and natural gas, coal, tar sands, shale oil, nuclear, wind, solar, hydropower, geothermal, wave/tidal and corn ethanol. Unfortunately, we found that few studies have been undertaken since the 1980s, and such as have been done are often marked more by advocacy than objectivity. The most recent summary of work and data on the EROI of fuels was conducted in the summer of 2007 at SUNY ESF and appeared on The Oil Drum website and in a readable summary by Richard Heinberg. This paper summarizes the findings of that study, and also those preceding and subsequent to it where available. It also summarizes issues raised by some concerning the findings of these studies and with the calculations within. While there are many who believe that such EROI studies are critical to understanding our financial and social future there seems to be very little interest by governments and industries in supporting this research or in using or promulgating such research as has been done. We view this as critical as our main fuels are progressively depleted and as we are faced with making extremely important decisions on a very meager analytical and data base, and with few scientists trained to cut through the reams of insufficiently analyzed energy advocacy saturating our media and the blogosphere.

Description: One of the most common denominators for almost any form of life is the existential need for water. This need has recently received much attention in the frame of sustainability discussions [1,2]. In addition, environmental sustainability and safe access to fresh water is one of the eight United Nation’s millennium development goals, and ultimately most conditions of life rely on water. Expected higher water demands for irrigation, industrial and household purposes outline the need for more investment in freshwater characterization and quantification. In addition, factors including climate change, large-scale reservoirs, re-channelling of streams, expansion of urban centres as well as chemical and microbial loading need to be taken into account.

Description: Ecodesign offers significant potential to reduce the environmental impacts of products. Whilst some integration of environmental considerations into design occurs in progressive companies when engineering the product, this only represents a small share of the possible design interventions to improve the environmental performance of products. For example, developing new product concepts to fulfill needs in a less environmentally harmful way and considering user related aspects offers a large, currently under-realized potential. This paper identifies industrial design (ID) consultancies as potential agents to tackle this issue on a strategic and operational basis. The extent to which this potential is currently applied was assessed by conducting a content analysis of websites of ID consultancies in Australia, China, and Germany. How ID consultancies represent their ecodesign practice is country-specific. Despite the differences, some ID consultancies in all countries announce and/or show the capability to develop completely new concepts and to influence user related factors to improve environmental performance. This shows their potential to address current shortcomings in ecodesign practice. As ID consultancies embracing that potential still are a minority, further research should be directed to a deeper examination of barriers and stimuli for ID consultancies to take up ecodesign.

Description: Energy Return on Investment (EROI) refers to how much energy is returned from one unit of energy invested in an energy-producing activity. It is a critical parameter for understanding and ranking different fuels. There were a number of studies on EROI three decades ago but relatively little work since. Now there is a whole new interest in EROI as fuels get increasingly expensive and as we attempt to weigh alternative energies against traditional ones. This special volume brings together a whole series of high quality new studies on EROI, as well as many papers that struggle with the meaning of changing EROI and its impact on our economy. One overall conclusion is that the quality of fuels is at least as important in our assessment as is the quantity. I argue that many of the contemporary changes in our economy are related directly to changing EROI as our premium fuels are increasingly depleted.

Description: Oil has played a crucial role in the United States’ continued but increasingly tenuous economic prosperity. The continued availability of cheap, high energy return on investment (EROI) oil, however, is increasingly in doubt. If cheap oil is increasingly constrained, how might that impact the American psychological sense of personal and national well-being? We employ general systems theory and certain key paradigms from psychology and sociology to predict the possible societal response to global peak oil and the declining EROI of whatever oil is produced. Based on these frameworks, the following three defense mechanisms seem likely to be employed by individuals and groups within society if and when confronted with stresses associated with declining oil availability. These are: denial of one’s passive helpless state, desire to establish a scapegoat, and arousal of affiliative needs and increased subgrouping. A group’s “survival” is a function of its unified sense of direction and the stability of necessary interdependencies and linkages. We suggest that the ability of the U.S. society, taken as a whole, to adapt to the stresses derived from the declining EROI of oil will increase during periods of moderate stress, and then decline after reaching its maximum ability to cope with stress. The integrity of interdependencies and linkages—power, communication, affect, and goals—must be preserved for continued social unity. Americans will need to acknowledge the reality of biophysical constraints if they are to adapt to the coming energy crisis.

Description: We model the low frequency electrical heating of submarine methane hydrate deposits located at depths between 1000 and 1500 m, and determine the energy return on energy invested (EROI) for this process. By means of the enthalpy method, we calculate the time-dependent heating of these deposits under applied electrical power supplied to a cylindrical heater located at the center of the reservoir and at variable depths. The conversion of the produced water to steam is avoided by limiting the heater temperature. We calculate the volume of methane hydrate that will melt and the energy equivalent of the gas thus generated. The partial energy efficiency of this heating process is obtained as the ratio of the gas equivalent energy to the applied electrical energy. We obtain EROI values in the range of 4 to 5, depending on the location of the heater. If the methane gas is used to generate the electrical energy required in the heating (in processes with a 33% efficiency), the effective EROI of the process falls in the range of 4/3 to 5/3.

Description: Using Pakistan and the Arctic as examples, this article examines security challenges arising from climate change. Pakistan is in crisis, and climate change, a transnational phenomenon perhaps better characterized as radical enviro-transformation, is an important reason. Its survival as a state may depend to great extent on how it responds to 2010’s devastating floods. In the Arctic, the ice cap is melting faster than predicted, as temperatures there rise faster than in almost any other region. Unmanaged, a complex interplay of climate-related conditions, including large-scale “ecomigration”, may turn resource competition into resource conflict. Radical enviro-transformation has repeatedly overborne the resilience of societies. War is not an inevitable by-product of such transformation, but in the 21st Century climate-related instability, from resource scarcity and “ecomigration”, will likely create increasingly undesirable conditions of insecurity. Weak and failing states are one of today’s greatest security challenges. The pace of radical enviro-transformation, unprecedented in human history, is accelerating, especially in the Arctic, where a new, open, rich, and accessible maritime environment is coming into being. The international community must work together to enhance security and stability, promote sustainability, and strengthen sovereignty. Radical enviro-transformation provides ample reason and plentiful opportunity for preventative, collaborative solutions focused broadly on adaptation to climate change, most particularly the effects of “ecomigration”. Nations must work together across the whole of government and with all instruments of national power to create conditions for human transformation—social, political, and economic—to occur stably and sustainably, so as to avoid or lessen the prospects for and consequences of conflict. Collaborative international solutions to environmental issues, i.e., solutions that mobilize and share technology and resources, will build nations and build peace. The military, through “preventative engagement” will play a more and more important role. Further research and analysis is needed to determine what changes in law and policy should be made to facilitate stable and secure “ecomigration” on an international scale, over a long timeline.

Description: Reporting on contributions to community development is one way gold mining companies communicate the expanse and depth of their commitment to social responsibility. These projects are intended to provide the mine-proximate communities with some of the wealth and other benefits generated by mine development in their locales. We raise questions about reporting and evaluation of community development projects undertaken by AngloGold Ashanti in the two communities of Nyakabale and Nyamalembo, near its Geita mining projects in the Lake Victoria goldfields of Tanzania. We use archival data and data obtained from field research conducted during different periods throughout 2005, 2007 and 2010 to compare what the company reports to have done with what is found on the ground. Our findings revealed that the corporate reporting is misleading, ambiguous, and omissive. Much of the effort labeled “community development” benefited the companies directly via infrastructure development, food supplies to the mine cafeteria, and worker health. We argue that, if Corporate Social Responsibility (CSR) projects are to be the primary way local people directly benefit from mine development, the relationship between the value of those projects and the wealth taken from the location should be considered, community projects should be well defined and differentiated from company-oriented projects, and community representatives should participate in monitoring the success and impact of community development projects.

Description: This paper analyzes the formation of Tulou villages and the characteristics of Tulou buildings. The genes of the Tulou are examined within the unique physical forms and the significant social culture background. The paper is concerned with how to apply the valuable genes in the preservation and sustainable development of Tulou with a special case analysis.

Description: It’s the new rock and roll. It’s the new black. Sustainability is trendy, and not just among hipsters and pop stars. The uncool chemical sector helped pioneer it, and today, companies inside and outside the sector have embraced it. But what have they embraced? Surely not the Brundtland definition of meeting “the needs of the present without compromising the ability of future generations to meet their own needs.”

Description: In recent decades, significant financial and professional resources have been invested in urban regeneration, housing renovation, and the revitalization of old neighborhoods, with considerable impacts on the social, physical, and economic structure of cities and their inhabitants. The first objective of this volume is to present the key issues related to these changes, which were discussed at an international symposium of experts organized by the International Association for People-Environment Studies and Housing and CSBE (Culture and Space in the Built Environment) Networks in Istanbul. The second objective is to show how concepts and methods in the field of people-environment studies can be successfully applied to study complex questions related to the revitalization of the built environment, both at the small scale of specific buildings and at the larger scale of neighborhoods.

Description: In this paper we are concerned with what explains public acceptance and support of environmental taxes. We examine findings in environmental psychology emphasizing that people’s (environmental) value-orientation is the dominant driver determining individuals’ support for pro-environmental policy instruments. We introduce a complementary model, mainly drawing upon findings in political science, suggesting that people’s support for policy instruments is dependent on their level of political trust and their trust in other citizens. More specifically, we analyze whether political trust and inter-personal trust affect individuals’ support for an increased carbon dioxide tax in Sweden, while checking their value orientation, self-interest, and various socio-economic values. We make use of survey data obtained from a mail questionnaire sent out to a random sample of 3,000 individuals in 2009. We find that apart from people’s values, beliefs, and norms, both political trust and interpersonal trust have significant effects on people's attitudes toward an increased tax on carbon dioxide.

Description: International policy development and expected climate change impacts such as flooding, landslides, and the extinction of sensitive species have forced countries around the Baltic Sea to begin working on national climate adaptation policies. Simultaneously, the EU is building both a central and a macro-regional Baltic Sea-wide adaptation strategy to support national policy developments. However, it yet remains unclear how these EU strategies will complement each other or national policies. This article analyzes the constraints and opportunities presented by this new institutional interplay and discusses the potential of the forthcoming EU strategies to support national policy. It does so by mapping how adaptation is institutionalized in two case countries, Sweden and Finland, and is organized in the two EU approaches. The vertical institutional interplay between scales is analyzed in terms of three factors: competence, capacity, and compatibility. Results indicate institutional constraints related to: risks of policy complexity for sub-national actors, an unclear relationship between the two EU approaches, an overly general approach to targeting contextualized climate change vulnerabilities, and a general lack of strategies to steer adaptation. However, there are also opportunities linked to an anticipated increased commitment to the national management of adaptation, especially related to biodiversity issues.

Description: The publication Corporate Fraud and Internal Control contains essential guidance for companies to examine and improve their fraud programs: Corporate governance legislation has become increasingly concerned with the ongoing resilience of organizations and, particularly, with their ability to resist corporate fraud from the lowest levels to the upper echelons of executive management. It has become unacceptable for those responsible for corporate governance to claim, "I didn't know". Corporate Fraud and Internal Control focuses on the appropriateness of the design of the system of internal controls in fraud risk mitigation, as well as the mechanisms to ensure effective implementation and monitoring on an ongoing basis. 

Description: Adaptive co-management is a governance approach gaining recognition. It emphasizes pluralism and communication; shared decision-making and authority; linkages within and among levels; actor autonomy; and, learning and adaptation. Adaptive co-management is just starting to be applied for climate change adaptation. In drawing upon adaptive co-management scholarship and a case in progress of application for climate change adaptation in Niagara, Canada, key considerations for the Barents Euro-Arctic Region are identified. Realistic expectations, sensitivity to context, and cultivating conditions for success are highlighted as key considerations for future efforts to implement adaptive co-management approaches in the Barents Region.

Description: The purpose of this study was to (1) discover consumer purchasing behaviors while shopping as a tourist and shopping at home, and (2) investigate tourist shopping preferences for an ideal shopping environment. A sample of 1,235 respondents participated in this study. Survey participants were asked to evaluate what store attributes they desired and what sources of information they used while selecting a store to shop in during their trips. Results indicate that consumers utilized various shopping channels while shopping in various environments. Also, different types of consumers exhibited clear preferences toward their ideal shopping environment. The results of this study are helpful for future service providers, tourism businesses, and tourism retailers to plan product development, provide better services, and equip a wider range of service skills.

Description: Tropical highland regions are experiencing rapid climate change. In these regions the adaptation challenge is complicated by the fact that elevation contrasts and dissected topography produce diverse climatic conditions that are often accompanied by significant ecological and agricultural diversity within a relatively small region. Such is the case for the Choke Mountain watersheds, in the Blue Nile Highlands of Ethiopia. These watersheds extend from tropical alpine environments at over 4000 m elevation to the hot and dry Blue Nile gorge that includes areas below 1000 m elevation, and contain a diversity of slope forms and soil types. This physical diversity and accompanying socio-economic contrasts demand diverse strategies for enhanced climate resilience and adaptation to climate change. To support development of locally appropriate climate resilience strategies across the Blue Nile Highlands, we present here an agroecosystem analysis of Choke Mountain, under the premise that the agroecosystem—the intersection of climatic and physiographic conditions with agricultural practices—is the most appropriate unit for defining adaptation strategies in these primarily subsistence agriculture communities. To this end, we present two approaches to agroecosystem analysis that can be applied to climate resilience studies in the Choke Mountain watersheds and, as appropriate, to other agroecologically diverse regions attempting to design climate adaptation strategies. First, a full agroecoystem analysis was implemented in collaboration with local communities. It identified six distinct agroecosystems that differ systematically in constraints and adaptation potential. This analysis was then paired with an objective landscape classification trained to identify agroecosystems based on climate and physiographic setting alone. It was found that the distribution of Choke Mountain watershed agroecosystems can, to first order, be explained as a function of prevailing climate. This suggests that the conditions that define current agroecosystems are likely to migrate under a changing climate, requiring adaptive management strategies. These agroecosystems show a remarkable degree of differentiation in terms of production orientation and socio-economic characteristics of the farming communities suggesting different options and interventions towards building resilience to climate change.

Description: Instrumental arguments linking inequality to environmental sustainability often suppose a negative relationship between inequality and social cohesion. While social cohesion is difficult to measure, there are measures of a narrower concept, social trust, and empirical studies have shown that social trust is negatively related to inequality. In this paper we test whether at least part of the observed relationship may be explained by income level, rather than income distribution. We use individual response data from the World Values Survey at the income decile level, and find evidence that income level is indeed important in explaining differences in levels of social trust, but it is insufficient to explain all of the dependence. In the sample used for the study, we find that both income level and income distribution help explain differences in social trust between countries.

Description: Land managers in the western US are beginning to understand that early 20th century forests displayed complex patterns of composition and structure at several different spatial scales, that there was interplay between patterns and processes within and across scales, and that these conditions have been radically altered by management. Further, they know that restoring integrity (see Definition of Terms) of these conditions has broad implications for the future sustainability (see Definition of Terms) of native species, ecosystem services, and ecological processes. Many are looking for methods to restore (see Definition of Terms) more natural landscape patterns of habitats and more naturally functioning disturbance regimes; all in the context of a warming climate. Attention is turning to evaluating whole landscapes at local and regional scales, deciphering recent changes in trajectories, and formulating landscape prescriptions that can restore ecological functionality and improve landscape resilience (see Definition of Terms). The business of landscape evaluation and developing landscape prescriptions is inherently complex, but with the advent of decision support systems, software applications are now available to conduct and document these evaluations. Here, we review several published landscape evaluation and planning applications designed with the Ecosystem Management Decision Support (EMDS) software, and present an evaluation we developed in support of a landscape restoration project. We discuss the goals and design of the project, its methods and utilities, what worked well, what could be improved and related research opportunities. For readability and compactness, fine and broad-scale landscape evaluations that could be a part of multi-scale restoration planning, are not further developed here.

Description: Waste and materials management, land use planning, transportation and infrastructure including water and energy can have indirect or direct beneficial impacts on the environment and public health. The potential for impact, however, is rarely viewed in an integrated fashion. To facilitate such an integrated view in support of community-based policy decision making, we catalogued and evaluated associations between common, publically available, Environmental (e), Health (h), and Sustainability (s) metrics and sociodemographic measurements (n = 10) for 50 populous U.S. cities. E, H, S indices combined from two sources were derived from component (e) (h) (s) metrics for each city. A composite EHS Index was derived to reflect the integration across the E, H, and S indices. Rank order of high performing cities was highly dependent on the E, H and S indices considered. When viewed together with sociodemographic measurements, our analyses further the understanding of the interplay between these broad categories and reveal significant sociodemographic disparities (e.g., race, education, income) associated with low performing cities. Our analyses demonstrate how publically available environmental, health, sustainability and socioeconomic data sets can be used to better understand interconnections between these diverse domains for more holistic community assessments.

Description: Water scarcity, land use conversion and cultural and ecosystem changes threaten the way of life for traditional irrigation communities of the semi-arid southwestern United States. Traditions are strong, yet potential upheaval is great in these communities that rely on acequia irrigation systems. Acequias are ancient ditch systems brought from the Iberian Peninsula to the New World over 400 years ago; they are simultaneously gravity flow water delivery systems and shared water governance institutions. Acequias have survived periods of drought and external shocks from changing economics, demographics, and resource uses. Now, climate change and urbanization threaten water availability, ecosystem functions, and the acequia communities themselves. Do past adaptive practices hold the key to future sustainability, or are new strategies required? To explore this issue we translated disciplinary understanding into a uniform format of causal loop diagrams to conceptualize the subsystems of the entire acequia-based human-natural system. Four subsystems are identified in this study: hydrology, ecosystem, land use/economics, and sociocultural. Important linkages between subsystems were revealed as well as variables indicating community cohesion (e.g., total irrigated land, intensity of upland grazing, mutualism). Ongoing work will test the conceptualizations with field data and modeling exercises to capture tipping points for non-sustainability and thresholds for sustainable water use and community longevity.

Description: Resolution A/HRC/RES/16/2 adopted by the UN Human Rights Council on 8 April 2011 declared access to safe drinking water and sanitation a human right. However many people around the globe including people with disabilities do not have access to safe drinking water, hygiene or sanitation facilities. Inaccessibility of clean water sources, hygiene and sanitation facilities negatively impacts among others health, education, the ability to work, and the ability to partake in social activities. This paper looks at the benefits of, and access barriers to, clean water and sanitation for people with disabilities.

Description: A nuclear fission-based energy system is described that is capable of supplying the energy needs of all of human civilization for a full range of human energy use scenarios, including both very high rates of energy use and strikingly-large amounts of total energy-utilized. To achieve such “planetary scale sustainability”, this nuclear energy system integrates three nascent technologies: uranium extraction from seawater, manifestly safe breeder reactors, and deep borehole disposal of nuclear waste. In addition to these technological components, it also possesses the sociopolitical quality of manifest safety, which involves engineering to a very high degree of safety in a straightforward manner, while concurrently making the safety characteristics of the resulting nuclear systems continually manifest to society as a whole. Near-term aspects of this nuclear system are outlined, and representative parameters given for a system of global scale capable of supplying energy to a planetary population of 10 billion people at a per capita level enjoyed by contemporary Americans, i.e., of a type which might be seen a half-century hence. In addition to being sustainable from a resource standpoint, the described nuclear system is also sustainable with respect to environmental and human health impacts, including those resulting from severe accidents.

Description: Large tracts (>1000 ha) of prairie are essential to the sustainability of grassland ecosystem services, yet in many ecoregions only small fragments remain. Glacial Ridge is among the largest prairie-wetland restorations ever attempted. Started in 2000, the 9000 ha project in northwest Minnesota, USA, was initiated to reconnect 14 small tallgrass prairie remnants. In all, 15,200 ha of contiguous habitat comprise the project's direct accomplishment. We created a partnership of more than 30 organizations, filled 177 km of drainage ditch, restored 1240 ha of wetland, and replanted 8100 ha. Flooding has been mitigated, water quality improved, and native vegetation reestablished. Animals not documented for decades have again occupied the site. Despite these accomplishments, the project would have been unnecessary if the land had been purchased in the 1970s, prior to conversion to agriculture, at one-tenth the restoration cost. Our challenges related to funding, differences in partners' restoration philosophy, community concerns about floods and tax losses, difficulties in obtaining seed, and follow-up management of invasive weeds. We summarize the restoration process and share basic principles that will help others to develop large-scale prairie restoration projects in the future.

Description: In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been established to obtain adequate moisture for winter wheat production. Current tilled fallow systems receive significant soil erosion through both wind and water. As a result, no-till chemical fallow systems are being adopted to mitigate erosion concerns. The objective of this study was to evaluate current Pacific Northwest cultivars under no-till chemical fallow and tilled fallow systems to identify cultivars adapted to a late-planted no-till system. Twenty-one cultivars were planted in a split-plot design with fallow type as the main plot and genotype as the sub-plot. Four replications were planted at two locations over three years. Data was collected on heading date, grain yield and grain volume weight. Analysis of variance was conducted on data from each year and location. Results were significant for all traits. Cultivars in the late-planted no-till system yielded an average of 39% less than the tilled fallow system. It is evident that cultivars vary in their adaptability and yield stability across production systems. Chukar and Eltan displayed the highest levels of yield stability, and growers who wish to plant winter wheat in a late-planted no-till system may benefit from choosing these cultivars.

Description: We must develop a serious approach to the fact that emotions, thoughts, assessments, and decisions originate in the mind, and as such are firmly based in human beings. We sense, experience, and act on the basis of internal processes, but which criteria constitute the basis of these processes and how does the internal “control system”, which we all have, function? Moreover, we need to take a closer look at the ways in which the organic and sustainable mechanisms of our living organisms are optimized and explicated. Otto Scharmer calls this process going from ego-system-awareness to eco-system-awareness. These are some of the questions which are at the heart of this book.

Description: A thorium-fueled water-cooled reactor core design approach that features a radially uniform composition of fuel rods in stationary fuel assembly and is fuel-self-sustaining is described. This core design concept is similar to the Reduced moderation Boiling Water Reactor (RBWR) proposed by Hitachi to fit within an ABWR pressure vessel, with the following exceptions: use of thorium instead of depleted uranium for the fertile fuel; elimination of the internal blanket; and elimination of absorbers from the axial reflectors, while increasing the length of the fissile zone. The preliminary analysis indicates that it is feasible to design such cores to be fuel-self-sustaining and to have a comfortably low peak linear heat generation rate when operating at the nominal ABWR power level of nearly 4000 MWth. However, the void reactivity feedback tends to be too negative, making it difficult to have sufficient shutdown reactivity margin at cold zero power condition. An addition of a small amount of plutonium from LWR used nuclear fuel was found effective in reducing the magnitude of the negative void reactivity effect and enables attaining adequate shutdown reactivity margin; it also flattens the axial power distribution. The resulting design concept offers an efficient incineration of the LWR generated plutonium in addition to effective utilization of thorium. Additional R&D is required in order to arrive at a reliable practical and safe design.

Description: In this research article the sustainability of different practices to collect the metal fraction of household waste in the Helsinki metropolitan area, Finland is examined. The study is carried out by calculating and comparing the greenhouse gas reduction potential of optional practices for collecting the metal fraction of household waste in the Helsinki metropolitan area, Finland. In order to locate the greenhouse gas reduction potential of the separate collection of the metallic fraction of municipal solid waste (MSW) collected from residential sources, a comparative carbon footprint analysis using Life Cycle Assessment (LCA) on six different waste management scenarios is carried out. The modeled system consisted of a waste collection system, transportation, and different waste management alternatives, including on-site separation, separation at the waste management facility as well as metallurgical recovery of separated scrap. The results show that, in terms of greenhouse gas emissions, separate collection and recycling of the metallic fraction of solid MSW at residential properties is the preferable option compared to a scenario with no source sorting and incineration of everything. According to this research scenario where the metal fraction of solid household waste was not source-separated or collected separately have clearly higher greenhouse gas emissions compared to all the other scenarios with separate collection for metals. In addition, metal recycling by regional collection points has considerably lower greenhouse gas emission potential than metal recycling by collection directly from residential properties.

Description: Life Cycle Assessment (LCA) is a decision support tool that can be used to assess the environmental performance of an integrated waste management system or to identify the system with the best performance through a comparative analysis of different scenarios. The results of the analysis depend primarily on how the scenarios to be compared are defined, that is on which waste fractions are assumed to be sent to certain treatments/destinations and in what amounts. This paper reviews LCAs of integrated waste management systems with the aim of exploring how the scenarios to be compared are defined in the preliminary phase of an LCA. This critical review highlighted that various criteria, more or less subjective, are generally used for the definition of scenarios. Furthermore, the number of scenarios identified and compared is generally limited; this may entail that only the best option among a limited set of possibilities can be selected, instead of identifying the best of all possible combinations. As a result, the advisability of identifying an integrated life cycle-based methodological approach that allows finding the most environmentally sound scenario among all of those that are theoretically possible is stressed.

Description: The most important target of the concept “sustainability” is to achieve fairness between generations. Its expanding interpolation leads to achieve fairness within a generation. Thus, it is necessary to discuss the role of nuclear power from the viewpoint of this definition. The history of nuclear power has been the control of the nuclear fission reaction. Once this is obtained, then the economy of the system is required. On the other hand, it is also necessary to consider the internalization of the external diseconomy to avoid damage to human society caused by the economic activity itself, due to its limited capacity. An extreme example is waste. Thus, reducing radioactive waste resulting from nuclear power is essential. Nuclear non-proliferation must be guaranteed. Moreover, the FUKUSHIMA accident revealed that it is still not enough that human beings control nuclear reaction. Further, the most essential issue for sustaining use of one technology is human resources in manufacturing, operation, policy-making and education. Nuclear power will be able to satisfy the requirements of sustainability only when these subjects are addressed. The author will review recent activities of a thorium molten-salt reactor (MSR) as a cornerstone for a sustainable society and describe its objectives and forecasts.

Description: The nuclear fuel cycle is the series of stages that nuclear fuel materials go through in a cradle to grave framework. The Once Through Cycle (OTC) is the current fuel cycle implemented in the United States; in which an appropriate form of the fuel is irradiated through a nuclear reactor only once before it is disposed of as waste. The discharged fuel contains materials that can be suitable for use as fuel. Thus, different types of fuel recycling technologies may be introduced in order to more fully utilize the energy potential of the fuel, or reduce the environmental impacts and proliferation concerns about the discarded fuel materials. Nuclear fuel cycle systems analysis is applied in this paper to attain a better understanding of the strengths and weaknesses of fuel cycle alternatives. Through the use of the nuclear fuel cycle analysis code CAFCA (Code for Advanced Fuel Cycle Analysis), the impact of a number of recycling technologies and the associated fuel cycle options is explored in the context of the U.S. energy scenario over 100 years. Particular focus is given to the quantification of Uranium utilization, the amount of Transuranic Material (TRU) generated and the economics of the different options compared to the base-line case, the OTC option. It is concluded that LWRs and the OTC are likely to dominate the nuclear energy supply system for the period considered due to limitations on availability of TRU to initiate recycling technologies. While the introduction of U-235 initiated fast reactors can accelerate their penetration of the nuclear energy system, their higher capital cost may lead to continued preference for the LWR-OTC cycle.

Description: Given that we must farm land in order to eat, the total environmental burden imposed by farming a crop, such as winter wheat in the UK, appears to be close to the minimum given current production techniques. The value of the services other than food production, such as flood water buffering, pollination, carbon storage and so on, that land can provide is relatively large compared with the value in reducing environmental burdens from pesticide use, nutrient pollution and greenhouse gas emissions that might arise by farming less intensively. More land will need to be brought into cultivation in order to provide the same amount of food if the intensity of farming is reduced and the resultant loss of ecosystem services (ES) outweighs the reduction in other burdens. Nevertheless, losses of nutrients, especially nitrogen (N), from agriculture are a serious concern and the current cost of the environmental footprint of agriculture is significant compared with the value of the food it produces. This article examines nutrient burdens and analyses the means by which the total environmental burden might be reduced relative to productivity. These include increasing the efficiency of farming, removing constraints to yield, and establishing multiple uses for land at the same time as farming. It concludes that agronomic measures which improve nutrient capture and which obtain more yield per unit area are valuable means to avoid degradation of environmental quality because both nutrient pollution and land consumption can be avoided.

Description: Although in Sweden the simultaneous use of forests for timber production and game hunting are both of socioeconomic importance it often leads to conflicting interests. This study examines forest stakeholder participation in improving game habitat to increase hunting opportunities as well as redistribute game activities in forests to help reduce browsing damage in valuable forest stands. The data for the study were collected from a nationwide survey that involved randomly selected hunters and forest owners in Sweden. An ordered logit model was used to account for possible factors influencing the respondents’ participation in improving game habitat. The results showed that on average, forest owning hunters were more involved in improving game habitat than non-hunting forest owners. The involvement of non-forest owning hunters was intermediate between the former two groups. The respondents’ participation in improving game habitat were mainly influenced by factors such as the quantity of game meat obtained, stakeholder group, forests on hunting grounds, the extent of risk posed by game browsing damage to the economy of forest owners, importance of bagging game during hunting, and number of hunting days. The findings will help in designing a more sustainable forest management strategy that integrates timber production and game hunting in forests.
