Opportunities and challenges for a sustainable energy future

Abstract: Access to clean, affordable and reliable energy has been a cornerstone of the world's increasing prosperity and economic growth since the beginning of the industrial revolution. Our use of energy in the twenty–first century must also be sustainable. Solar and water–based energy generation, and engineering of microbes to produce biofuels are a few examples of the alternatives. This Perspective puts these opportunities into a larger context by relating them to a number of aspects in the transportation and electricity generation sectors. It also provides a snapshot of the current energy landscape and discusses several research and development opportunities and pathways that could lead to a prosperous, sustainable and secure energy future for the world.

Closing yield gaps through nutrient and water management

Abstract: In the coming decades, a crucial challenge for humanity will be meeting future food demands without undermining further the integrity of the Earth’s environmental systems1, 2, 3, 4, 5, 6. Agricultural systems are already major forces of global environmental degradation4, 7, but population growth and increasing consumption of calorie- and meat-intensive diets are expected to roughly double human food demand by 2050 (ref. 3). Responding to these pressures, there is increasing focus on ‘sustainable intensification’ as a means to increase yields on underperforming landscapes while simultaneously decreasing the environmental impacts of agricultural systems2, 3, 4, 8, 9, 10, 11. However, it is unclear what such efforts might entail for the future of global agricultural landscapes. Here we present a global-scale assessment of intensification prospects from closing ‘yield gaps’ (differences between observed yields and those attainable in a given region), the spatial patterns of agricultural management practices and yield limitation, and the management changes that may be necessary to achieve increased yields. We find that global yield variability is heavily controlled by fertilizer use, irrigation and climate. Large production increases (45% to 70% for most crops) are possible from closing yield gaps to 100% of attainable yields, and the changes to management practices that are needed to close yield gaps vary considerably by region and current intensity. Furthermore, we find that there are large opportunities to reduce the environmental impact of agriculture by eliminating nutrient overuse, while still allowing an approximately 30% increase in production of major cereals (maize, wheat and rice). Meeting the food security and sustainability challenges of the coming decades is possible, but will require considerable changes in nutrient and water management.

Transdisciplinary research in sustainability science: practice, principles, and challenges

Abstract: There is emerging agreement that sustainability challenges require new ways of knowledge production and decision-making. One key aspect of sustainability science, therefore, is the involvement of actors from outside academia into the research process in order to integrate the best available knowledge, reconcile values and preferences, as well as create ownership for problems and solution options. Transdisciplinary, community-based, interactive, or participatory research approaches are often suggested as appropriate means to meet both the requirements posed by real-world problems as well as the goals of sustainability science as a transformational scientific field. Dispersed literature on these approaches and a variety of empirical projects applying them make it difficult for interested researchers and practitioners to review and become familiar with key components and design principles of how to do transdisciplinary sustainability research. Starting from a conceptual model of an ideal–typical transdisciplinary research process, this article synthesizes and structures such a set of principles from various strands of the literature and empirical experiences. We then elaborate on them, looking at challenges and some coping strategies as experienced in transdisciplinary sustainability projects in Europe, North America, South America, Africa, and Asia. The article concludes with future research needed in order to further enhance the practice of transdisciplinary sustainability research.

Business Models for Sustainable Innovation: State of the Art and Steps Towards a Research Agenda

Abstract: The aim of this paper is to advance research on sustainable innovation by adopting a business model perspective. Through a confrontation of the literature on both topics we find that research on sustainable innovation has tended to neglect the way in which firms need to combine a value proposition, the organization of the upstream and downstream value chain, and a financial model, in order to bring sustainability innovations to the market. Therefore, we review the current literature on business models in the contexts of technological, organizational, and social sustainability innovations. As the current literature does not offer a general conceptual definition of sustainable business models, we propose examples of normative 'boundary conditions' that business models should meet in order to support sustainable innovations. Finally, we sketch the outline of a research agenda by formulating a number of guiding questions.

The Impact of Corporate Sustainability on Organizational Processes and Performance

Abstract: We investigate the effect of corporate sustainability on organizational processes and performance. Using a matched sample of 180 US companies, we find that corporations that voluntarily adopted sustainability policies by 1993 - termed as High Sustainability companies - exhibit by 2009 distinct organizational processes compared to a matched sample of companies that adopted almost none of these policies - termed as Low Sustainability companies. The boards of directors of High Sustainability companies are more likely to be formally responsible for sustainability and top executive compensation incentives are more likely to be a function of sustainability metrics. High Sustainability companies are more likely to have established processes for stakeholder engagement, to be more long-term oriented, and to exhibit higher measurement and disclosure of nonfinancial information. Finally, High Sustainability companies significantly outperform their counterparts over the long-term, both in terms of stock market and accounting performance.

World Energy Outlook 2012

Abstract: Industry and government decision-makers and others with a stake in the energy sector all need WEO-2012. It presents authoritative projections of energy trends through to 2035 and insights into what they mean for energy security, environmental sustainability and economic development. Oil, coal, natural gas, renewables and nuclear power are all covered, together with an update on climate change issues. Global energy demand, production, trade, investment and carbon dioxide emissions are broken down by region or country, by fuel and by sector. Special strategic analyses cover -What unlocking the purely economic potential for energy efficiency could do, country by country and sector by sector, for energy markets, the economy and the environment. -The Iraqi energy sector, examining both its importance in satisfying the country’s own needs and its crucial role in meeting global oil and gas demand. -An examination of the cost of delaying action on climate change. -The water-energy nexus,as water resources become increasingly stressed and access more contentious. -Measures of progress towards providing universal access to modern energy services. There are many uncertainties; but many decisions cannot wait. The insights of WEO‑2012 are invaluable to those who must shape our energy future.

The ecosystem services agenda:bridging the worlds of natural science and economics, conservation and development, and public and private policy

Abstract: The Ecosystem Services Journal starts in 2012 with a formidable basis in the reports and books from the Millennium Ecosystem Assessment and TEEB projects. Following a half-century history of growing awareness and associated scientific based policy development a bridging concept with natural and social science notions was developed and coined “ecosystem services”. The agenda for the journal Ecosystem Services, presented in this introductory paper to the Journal Ecosystem Services is aimed at scientists and policy analysts who consider contributing to better knowledge and better use of that knowledge about ecosystem services. This should include knowledge of the ecological systems that provide the services, the economic systems that benefit from them, and the institutions that need to develop effective codes for a sustainable use. The agenda is derived from the experience of the authors in science and policy analysis and extended with some of the recommendations from the TEEB book for national and international policy making emphasising the science—policy—practice linkage, which is the philosophy of the Journal.

Growing Grassroots Innovations: Exploring the Role of Community-Based Initiatives in Governing Sustainable Energy Transitions:

Abstract: The challenges of sustainable development (and climate change and peak oil, in particular) demand system-wide transformations in sociotechnical systems of provision. An academic literature around coevolutionary innovation for sustainability has recently emerged as an attempt to understand the dynamics and directions of such sociotechnical transformations, which are termed 'sustainability transitions'. This literature has previously focused on market-based technological innovations. Here we apply it to a new context of civil-society-based social innovation and examine the role of community-based initiatives in a transition to a low-carbon sustainable economy in the UK. We present new empirical research from a study of the UK's Transition Towns movement (a 'grassroots innovation') and assess its attempts to grow and infl uence wider societal sociotechnical systems. By applying strategic niche management theory to this civil society context, we deliver theoretically informed practical recommendations for this movement to diff use beyond its niche: to foster deeper engagement with resourceful regime actors; to manage expectations more realistically by delivering tangible opportunities for action and participation; and to embrace a community-based, action-oriented model of social change (in preference to a cognitive theory of behaviour change). Furthermore, our study indicates areas where theory can be refi ned to better explain the growth and broader impacts of grassroots innovations —namely, through a fuller appreciation of the importance of internal niche processes, by understanding the important role of identity and group formation, and by resolving how social practices change in grassroots innovations.

Sustainable supply management: An empirical study

Abstract: Sustainable business development has received much attention over the past decade owing to the significant attention given by governments and both profit and not-for-profit organizations to environmental, social and corporate responsibility. The emergence of a changing economic order has also made companies around the world seriously think about manufacturing and service sustainability. Global markets and operations have prompted companies to revisit their corporate, business and functional strategies in addition to focusing on outsourcing, virtual enterprise and supply chain management. Sustainability research on supply management has received limited attention. Nevertheless, considering the physically disbursed enterprise environment, supply management is critical for organizational competitiveness. Realizing the importance of sustainability in supply management, an attempt has been made to develop a theoretical framework and then to study the framework by means of an empirical study using perceptions and practices of selected French companies. Finally, a summary of findings and conclusions are reported.

Business Cases for Sustainability: The Role of Business Model Innovation for Corporate Sustainability

Abstract: A considerable body of literature deals with the creation of economic value while increasing corporate environmental and social performance. Some publications even focus on the business case for sustainability which aims at increasing corporate economic value through environmental or social measures. The existence of a business case for sustainability is, however, mostly seen as an ad hoc measure, a supplement to the core business, or simply a coincidence. As a contrast, this paper argues that business model innovations may be required to support a systematic, ongoing creation of business cases for sustainability. A framework for business model innovation is proposed as a means to strategically create business cases on a regular basis as an inherent, deeply integrated element of business activities.

Urban land teleconnections and sustainability

Abstract: This paper introduces urban land teleconnections as a conceptual framework that explicitly links land changes to underlying urbanization dynamics. We illustrate how three key themes that are currently addressed separately in the urban sustainability and land change literatures can lead to incorrect conclusions and misleading results when they are not examined jointly: the traditional system of land classification that is based on discrete categories and reinforces the false idea of a rural–urban dichotomy; the spatial quantification of land change that is based on place-based relationships, ignoring the connections between distant places, especially between urban functions and rural land uses; and the implicit assumptions about path dependency and sequential land changes that underlie current conceptualizations of land transitions. We then examine several environmental “grand challenges” and discuss how urban land teleconnections could help research communities frame scientific inquiries. Finally, we point to existing analytical approaches that can be used to advance development and application of the concept.

Making connections: a review of supply chain management and sustainability literature

Abstract: Purpose – The objective of this paper is to investigate systematically the discipline of supply chain management (SCM) within the context of sustainability. The two concepts are increasingly aligned, and sustainable supply chain management (SSCM) represents an evolving field where they explicitly interact. Given their complex and holistic nature, breaking down the literature to understand its structures, processes, connections and limitations can provide an objective view of the status of research in these highly important fields, identifying key areas for future research/theory development.Design/methodology/approach – A systematic review of current SCM literature is carried out, specifically in relation to the social and environmental dimensions of sustainability.Findings – SSCM and the integration of sustainability into supply chains is a significant but evolving field evidenced by a current bias in the literature towards theory development and highly qualitative research methods. The environmental dim...

Sustainable manufacturing: trends and research challenges

Abstract: Sustainability is and will be a crucial issue for the present and future generations. The current assumption that natural resources are infinite and that the regenerative capacity of the environment is able to compensate for all human action is no longer acceptable. Hence, sustainability issues will influence all organisational aspects of the human life, from the economical, political, social and environmental points of view. The reason is simple: until now, all human activities have been based on the paradigm of unlimited resources and unlimited world's capacity for regeneration; from now on, the awareness of the termination of this assumption means that all related behavioural models must be changed. This is a very impressive objective embracing all fields of culture, economy, technology and much more. A continuing effort, together with a reasonable time span, will be required to pursue this goal. Fortunately, nature and the environment are capable of self-regulation and will give man a chance to recove...

Exploiting diversity and synthetic biology for the production of algal biofuels

Abstract: Modern life is intimately linked to the availability of fossil fuels, which continue to meet the world's growing energy needs even though their use drives climate change, exhausts finite reserves and contributes to global political strife. Biofuels made from renewable resources could be a more sustainable alternative, particularly if sourced from organisms, such as algae, that can be farmed without using valuable arable land. Strain development and process engineering are needed to make algal biofuels practical and economically viable.

Extending sustainability to suppliers: a systematic literature review

Abstract: Purpose – To make their supply chains more socially responsible, many companies are implementing supplier assessment tools and collaborative practices. The aim of this paper is to provide a systematic literature review on the governance structures used to extend sustainability to suppliers. More specifically, the authors aim to answer two questions: “What is the impact of these mechanisms or governance structures on sustainable performance?” and “What are the enablers of these mechanisms?”.Design/methodology/approach – A structured literature review is carried out that analyses published studies, evaluates contributions, summarises knowledge and identifies managerial implications and lines for further research.Findings – Both assessment and collaboration have a positive impact on environmental performance and corporate social responsibility, although the most recent collaborative paradigm stresses that assessment alone is not enough. Some enablers of these practices are identified.Research limitations/imp...

Socio-technical regimes and sustainability transitions: Insights from political ecology

Abstract: Sustainability is increasingly becoming a core focus of geography, linking subfields such as urban, economic, and political ecology, yet strategies for achieving this goal remain illusive. Socio-technical transition theorists have made important contributions to our knowledge of the challenges and possibilities for achieving more sustainable societies, but this body of work generally lacks consideration of the influences of geography and power relations as forces shaping sustainability initiatives in practice. This paper assesses the significance for geographers interested in understanding the space, time, and scalar characteristics of sustainable development of one major strand of socio-technical transition theory, the multi-level perspective on socio-technical regime transitions. We describe the socio-technical transition approach, identify four major limitations facing it, show how insights from geographers – particularly political ecologists – can help address these challenges, and briefly examine a c...

Food webs: reconciling the structure and function of biodiversity

Abstract: The global biodiversity crisis concerns not only unprecedented loss of species within communities, but also related consequences for ecosystem function. Community ecology focuses on patterns of species richness and community composition, whereas ecosystem ecology focuses on fluxes of energy and materials. Food webs provide a quantitative framework to combine these approaches and unify the study of biodiversity and ecosystem function. We summarise the progression of food-web ecology and the challenges in using the food-web approach. We identify five areas of research where these advances can continue, and be applied to global challenges. Finally, we describe what data are needed in the next generation of food-web studies to reconcile the structure and function of biodiversity.

Taking the “Waste” Out of “Wastewater” for Human Water Security and Ecosystem Sustainability

Abstract: Humans create vast quantities of wastewater through inefficiencies and poor management of water systems. The wasting of water poses sustainability challenges, depletes energy reserves, and undermines human water security and ecosystem health. Here we review emerging approaches for reusing wastewater and minimizing its generation. These complementary options make the most of scarce freshwater resources, serve the varying water needs of both developed and developing countries, and confer a variety of environmental benefits. Their widespread adoption will require changing how freshwater is sourced, used, managed, and priced.
