Community Supported Sustainability COMMUNITY SUPPORTED SUSTAINABILITY: HOW ECOVILLAGES MODEL MORE SUSTAINABLE COMMUNITY Jesse Sherry Rutgers University New Brunswick, New Jersey 2014 © 2014 Jesse Sherry ALL RIGHTS RESERVED ii COMMUNITY SUPPORTED SUSTAINABILITY: HOW ECOVILLAGES MODEL MORE SUSTAINABLE COMMUNITY By JESSE SHERRY A dissertation submitted to the Graduate School-New Brunswick Rutgers, The State University of New Jersey In partial fulfillment of the requirements for the degree of Doctor of Philosophy Graduate Program in Planning and Public Policy Written under the direction of Dr. Clinton Andrews and approved by ________________________ ________________________ ________________________ ________________________ New Brunswick, New Jersey May, 2014 iii ABSTRACT OF THE DISSERTATION Community Supported Sustainability: How Ecovillages Model More Sustainable Community By JESSE SHERRY Dissertation Director: Dr. Clinton Andrews Ecovillages are small, intentional communities which focus on reducing environmental impact while creating a community that incorporates the natural world. Despite varying approaches, each ecovillage attempts to create a community that integrates the social, economic, and environmental dimensions of sustainability. This study investigates several of these communities to better understand two key questions: 1) to what extent do ecovillage residents have a lower environmental impact than residents of nearby communities and the national average? and 2) how is the reduction in environmental impact achieved? These questions are addressed through the use of life cycle assessment and qualitative case studies of three sites, specifically one suburban and two rural ecovillages. Comparisons with nearby communities and the national average are made, and the results show that the case study ecovillages have a much lower per capita environmental impact. My research suggests that this is achieved through a combination of physical (village building and planning) and behavioral adaptations supported by community ideals and norms. iv ACKNOWLEDGEMENTS Over the past eight years, I have received support and encouragement from a great number of individuals. Dr. Clinton Andrews has been a supportive and insightful mentor throughout this process. I would like to thank my dissertation committee of Dr. Uta Krogmann, Dr. Kathe Newman, and Dr. Hal Salzman for their support over the past three years as I moved from an idea to a completed study. In addition, Rolando Rodriguez and Ben Klemens both provided valuable methodological advice. During data collection and writing Sarah Wilson Sherry spent countless hours proofreading and listening to me talk about my research. This project would never have been possible without the generous assistance and cooperation of the members of Ecovillage at Ithaca, Sirius, and Earthaven. They welcomed me into their homes, shared the details of their lives, and encouraged me with their interest. In particular I would like to thank Dan Greenberg for his insight into intentional community, Liz Walker for her willingness to take time for one more researcher, and Susan Wolf for providing a home away from home. v Table of Contents Chapter 1: Introduction ................................................................................................................... 1 Chapter 2.

  • Local Utopia As Unobtrusive Resistance: the Greek Village Micro-Economy
    Local Utopia as Unobtrusive Resistance: The Greek Village Micro-Economy Marina Karides Florida Atlantic University [email protected] In late 2008 Athenian youths, triggered by extreme police violence, took to the streets with collective and intensive protests against the growing poverty, unemployment, and political corruption in Greece. The subsequent, regular protests in urban Greece speak not only to the rejection of Greek governance but also to the political and economic promise of the Euro-zone falsely promoted as a boon for its periphery. The oft-reiterated headline “Athens is burning” is varyingly used by left and right media reporting on Greece and its population’s fierce dissent. Yet Greece is not Athens. While half the nation’s population lives in urban centers such as Athens, Thessaloniki, and Patra, the other lives in small agricultural villages often mixed with low-key tourism. It is these small independent and diverse communities, or “meta-industrial populations” (Salleh), in which local agriculture literally feeds the immediate population and its tourists, offering a modest blueprint for a convivial economy. In this Symposium Ariel Salleh highlights the foundations of real ecological sustainability in the work of peasants, women, and Indigenous communities versus the commodification of a green economy. In Greece and its villages, it is not only the historical practices of environmental sustainability – a hallmark of island populations – that is to be showcased, but also an economic culture oriented towards sharing, generosity, and negotiation that is characteristic of many non-core communities. Analyses of the Greek economy are inconclusive; conservative commentators focus on political clientelism, a bloated state sector, migration and the informal economy.

  • Geoengineering in the Anthropocene Through Regenerative Urbanism
    geosciences Review Geoengineering in the Anthropocene through Regenerative Urbanism Giles Thomson * and Peter Newman Curtin University Sustainability Policy Institute, Curtin University, Perth 6102, WA, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-8-9266-9030 Academic Editors: Carlos Alves and Jesus Martinez-Frias Received: 26 June 2016; Accepted: 13 October 2016; Published: 25 October 2016 Abstract: Human consumption patterns exceed planetary boundaries and stress on the biosphere can be expected to worsen. The recent “Paris Agreement” (COP21) represents a major international attempt to address risk associated with climate change through rapid decarbonisation. The mechanisms for implementation are yet to be determined and, while various large-scale geoengineering projects have been proposed, we argue a better solution may lie in cities. Large-scale green urbanism in cities and their bioregions would offer benefits commensurate to alternative geoengineering proposals, but this integrated approach carries less risk and has additional, multiple, social and economic benefits in addition to a reduction of urban ecological footprint. However, the key to success will require policy writers and city makers to deliver at scale and to high urban sustainability performance benchmarks. To better define urban sustainability performance, we describe three horizons of green urbanism: green design, that seeks to improve upon conventional development; sustainable development, that is the first step toward a net zero impact; and the emerging concept of regenerative urbanism, that enables biosphere repair. Examples of green urbanism exist that utilize technology and design to optimize urban metabolism and deliver net positive sustainability performance. If mainstreamed, regenerative approaches can make urban development a major urban geoengineering force, while simultaneously introducing life-affirming co-benefits to burgeoning cities.

  • Exploring Pro-Environmental Behavior Experts' Coping Strategies
    sustainability Article How to Cope with Perceived Tension towards Sustainable Consumption? Exploring Pro-Environmental Behavior Experts’ Coping Strategies Gabriele Torma Department of Management, Aarhus BSS, Aarhus University, Fuglesangs Allé, DK-8210 Aarhus, Denmark; [email protected]; Tel.: +45-87164862 Received: 23 September 2020; Accepted: 20 October 2020; Published: 22 October 2020 Abstract: Pro-environmental behavior experts (PEBEXs) encounter tensions associated with sustainable consumption, just like other individuals. What distinguishes them is their high level of knowledge, motivation, and reflection on climate change topics, as intended by many downstream policy interventions targeting individual consumption behavior. Based on 31 problem-centered interviews with PEBEXs, we found two general coping strategies: contributing to maximizing sustainable consumption and accommodating to the minimization of perceived tension. These coping strategies offer a promising source of information for individuals in general on how to drive personal consumption behavior in more sustainable directions and how to deal with accompanying barriers and tensions. Because coping strategies can be trained, the introduced strategies can support the design of interventions targeting individual consumption decisions. Furthermore, we emphasize the importance of accompanying upstream interventions, such as structural changes, to support individual behavior changes. Keywords: pro-environmental behavior; sustainable consumption; climate change; coping strategies; ecological coping; experts 1. Introduction Climate change is arguably one of the most critical and urgent problems of our time and represents what Rittel and Webber [1] referred to as a “wicked problem”. Wicked problems are problems that cannot be resolved by one individual alone because they are complex, ill-structured, and of public concern. They have no definite formulation, have no ‘true-false’ but rather ‘good-bad’ solutions, and are symptoms of other problems [1,2].

  • Shifting the Peak Oil “Debate” to Strategic Management
    Shifting the Peak Oil “Debate” to Strategic Management Sally Odland March 2007 It’s time to initiate a real public discourse on the Peak Oil “debate” from a management perspective. On the one side, there are the “Peak Oilers”, urgently warning that world oil production will soon hit its maximum, if it hasn’t already. Many predict dire ramifications for the economy and our current way of life. They are a disparate band, but include some prominent businessmen, members of Congress and the Intelligence community. On the other side, a number of government agencies, oil company CEOs, energy consultants and economists are publicly assuring us there is plenty of oil. They say production will not peak until at least 2030, maybe later…assuming we get access to politically and environmentally extreme areas and invest enough. Each side fires predictable volleys from well-entrenched positions. One side clearly has more corporate clout and better access to the mainstream media. The other uses the internet with the tenacity of resistance fighters. But bottom line, everyone is speculating. There’s a conspicuous lack of verifiable data about how much oil is really out there and who has the capacity to produce more. How can ordinary people and businesses decide whom to believe, much less whether to act, in the face of such polarized viewpoints? Out here in daily life, managers – and by that I mean anyone who makes conscious resource allocation decisions for themselves or others – frequently must take action in the face of incomplete and contradictory information. So, instead of arguing about who has correctly predicted the exact date for peak oil, how about shifting the debate? Let’s examine the spectrum of possibilities, the assumptions underlying them, and their probability, uncertainty and risk.

  • A Menu for Change
    A Menu for Change Using behavioural science to promote sustainable diets around the world The Behavioural Insights Team / A Menu for Change 2 The Behavioural Insights Team / A Menu for Change Toby Park, Head of Energy & Sustainability, The Behavioural Insights Team [email protected] Acknowledgements This report has benefitted from several individuals’ contributions. With particular thanks for substantive research support and contributions to early content and the structure of the report, to Emma Garnett (University of Cambridge) and Brittney Titus (University of Oxford), both supporting us while at placement at BIT. With thanks also to Elisabeth Costa (BIT), Dr Filippo Bianchi (BIT), Dr Jessica Barker (BIT), and Dr Christian Reynolds (University of Sheffield) for their valuable feedback and comments. This is a long report. We hope you’ll read it cover-to-cover, but if not, it’s written to allow you to dip into individual sections. Look out for the short orange descriptions at the beginning of each chapter to keep track of where you are. Sections 1.1-1.2 introduce the problem, and make the rationale for shifting global diets. This will be familiar ground for environmental scientists. Section 1.3 looks at the current state, and emerging trends, in diets around the world, and Section 1.4 highlights the many historical occasions when diets have radically changed through technological innovation or deliberate intervention from government and industry. Section 1.5 acknowledges the sensitivities of this topic, and offers some reflections on how we might navigate public and political consent. We don’t have all the answers here but give a series of recommendations for building public support and developing effective policy.
