The Ecological Footprint Emerged As a Response to the Challenge of Sustainable Development, Which Aims at Securing Everybody's Well-Being Within Planetary Constraints
16 Ecological Footprint accounts The Ecological Footprint emerged as a response to the challenge of sustainable development, which aims at securing everybody's well-being within planetary constraints. It sharpens sustainable development efforts by offering a metric for this challenge’s core condition: keeping the human metabolism within the means of what the planet can renew. Therefore, Ecological Footprint accounting seeks to answer one particular question: How much of the biosphere’s (or any region’s) regenerative capacity does any human activity demand? The condition of keeping humanity’s material demands within the amount the planet can renew is a minimum requirement for sustainability. While human demands can exceed what the planet renew s for some time, exceeding it leads inevitably to (unsustainable) depletion of nature’s stocks. Such depletion can only be maintained temporarily. In this chapter we outline the underlying principles that are the foundation of Ecological Footprint accounting. 16 Ecological Footprint accounts Runninghead Right-hand pages: 16 Ecological Footprint accounts Runninghead Left-hand pages: Mathis Wackernagel et al. 16 Ecological Footprint accounts Principles 1 Mathis Wackernagel, Alessandro Galli, Laurel Hanscom, David Lin, Laetitia Mailhes, and Tony Drummond 1. Introduction – addressing all demands on nature, from carbon emissions to food and fibres Through the Paris Climate Agreement, nearly 200 countries agreed to keep global temperature rise to less than 2°C above the pre-industrial level. This goal implies ending fossil fuel use globally well before 2050 ( Anderson, 2015 ; Figueres et al., 2017 ; Rockström et al., 2017 ). The term “net carbon” in the agreement further suggests humanity needs far more than just a transition to clean energy; managing land to support many competing needs also will be crucial. -

The Greifswalder Theory of Strong Sustainability and Its Relevance for Policy Advice in Germany and the EU
Sustainability Science – The Greifswalder Theory of Strong Sustainability and its relevance for policy advice in Germany and the EU Ralf Döring* , Barbara Muraca 1 *Johann Heinrich von Thünen - Federal Institute for Rural Areas, Forestry and Fisheries, Germany Abstract The Greifswald approach was developed over many years in the co-operation of environmental philosophers and ecological economists. The theory combines normative arguments on our responsibilities for current and future generations (intra- and intergenerational justice), the conceptual debate on weak vs. strong sustainability, a new concept for natural capital with practical applications in three sectors: fisheries, agriculture and climate change policy. It was developed as an answer to the increasingly vague understanding of the sustainability concept in the political arena, which gives politicians the possibility of subsuming under it all sorts of different programs and strategies. A sharper definition of the concept is needed that offers a non-arbitrary orientation ground for action to end the further loss of essential parts of natural capital without becoming too rigid and exclusive of differences. In this paper we give firstly a short overview about the philosophical background of the theory and about the conceptual debate on weak and strong sustainability. Secondly, we depict our concept of Natural Capital, which draws on Georgescu-Roegen’s systematic framework of fund, stock, services, and flows and focuses on a central characteristic of nature: its (re)productivity. Accordingly, natural capital consists of living funds, non-living funds, and stocks. This differentiation offers a helpful ground for identifying specific preservation goals for the different parts of natural capital and can be successfully employed in the advice for policy makers (as it has been the case with the German Advisory Council for the Environment over a decade). -
Dec Issue # 76 What You Have Missed! MARINA BARRAGE’S 10TH ANNIVERSARY FINALE 26-28 Oct 2018
Dec Issue # 76 What you have missed! MARINA BARRAGE’S 10TH ANNIVERSARY FINALE 26-28 Oct 2018 The end of October has held particular significance for PUB since 2008 – on 31 October 2008, the Marina Barrage was officially opened after decades of hard work and planning, realising former Prime Minister Lee Kuan Yew’s vision of a freshwater reservoir in the city. In celebration of this milestone, a 3-day carnival was held from 26-28 October, bringing people a slew of fun and excitement. There were over a hundred stalls for the shopaholics, foodies, and activities for families and even our environmentally-conscious friends! There were specially-curated foods reminiscent of the Barrage’s crest gates and gigantic pumps, both of which work to maintain consistent water levels in the Marina Reservoir and alleviate flooding in low-lying areas of the city. Free river cruises for the public to appreciate the efforts that go into keeping the reservoir waters clean beautiful. The Barrage came alive at night with twinkling fairy lights and the sounds of bustle, when shoppers did what they did best and sourced for their kicks. Many stalls boasted self-designed and handmade items, and the prices of the little trinkets sure were easy on the pocket! With 2018 designated as the year of Climate Action, and the Marina Barrage an icon of water security and sustainability, it only made sense that there be a Sustainable Zone at the Finale! Members of the public could sign up for activities and workshops to try their hand at upcycling everyday items into useful stuff, like milk cartons into coin pouches, and throwaway wallpaper samples into wallets! Image credit: Terra SG The highlight of the three days was when Deputy Prime Minister and Coordinating Minister for National Security, Mr Teo Chee Hean, graced the celebrations on 27 October. -

Latouche writes in Farewell to Growth that “we resist, and must resist all forms of racism and discrimination (skin color, sex, religion, ethnicity)”, biases he insist are “all too common in the West today.” Latouche’s ideas are important for considering “degrowth”, because racial bias and the historical problems presented by that bias, in the United States, continues despite efforts to address it in a significant manner. The World is Yours discusses “degrowth” , economic growth and racial inequality, seeking to not only provide a better understanding of the recent social, legal and political meaning of these terms, but also the difficulties presented by these ideas today in a world increasingly committed to economic growth, even at the expense of human existence. How can a new economic paradigm be pursued that is more sustainable? Will African-Americans and other groups of color and nations of color accept “degrowth” if the US begins to implement a real sustainable agenda that addresses racial inequality?

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. -
Restoring Streams in an Urbanizing World
Freshwater Biology (2007) 52, 738–751 doi:10.1111/j.1365-2427.2006.01718.x Restoring streams in an urbanizing world EMILY S. BERNHARDT* AND MARGARET A. PALMER† *Department of Biology, Duke University, Durham, NC, U.S.A. †Chesapeake Biological Laboratory, University of Maryland Center for Environmental Science, Solomons, MD, U.S.A. SUMMARY 1. The world’s population is increasingly urban, and streams and rivers, as the low lying points of the landscape, are especially sensitive to and profoundly impacted by the changes associated with urbanization and suburbanization of catchments. 2. River restoration is an increasingly popular management strategy for improving the physical and ecological conditions of degraded urban streams. In urban catchments, management activities as diverse as stormwater management, bank stabilisation, channel reconfiguration and riparian replanting may be described as river restoration projects. 3. Restoration in urban streams is both more expensive and more difficult than restoration in less densely populated catchments. High property values and finely subdivided land and dense human infrastructure (e.g. roads, sewer lines) limit the spatial extent of urban river restoration options, while stormwaters and the associated sediment and pollutant loads may limit the potential for restoration projects to reverse degradation. 4. To be effective, urban stream restoration efforts must be integrated within broader catchment management strategies. A key scientific and management challenge is to establish criteria for determining when the design options for urban river restoration are so constrained that a return towards reference or pre-urbanization conditions is not realistic or feasible and when river restoration presents a viable and effective strategy for improving the ecological condition of these degraded ecosystems. -
The Sustainability of Waste Management Models in Circular Economies
sustainability Article The Sustainability of Waste Management Models in Circular Economies Carmen Avilés-Palacios 1 and Ana Rodríguez-Olalla 2,* 1 Escuela Técnica Superior de Ingeniería de Montes, Forestal y del Medio Natural, Universidad Politécnica de Madrid, c/José Antonio Novais 10, 28040 Madrid, Spain; [email protected] 2 Departamento Economía de la Empresa (ADO), Economía Aplicada II y Fundamentos Análisis Económico, Universidad Rey Juan Carlos, Paseo de los Artilleros s/n, Vicálvaro, 28032 Madrid, Spain * Correspondence: [email protected]; Tel.: +34-910671632 Abstract: The circular economy (CE) is considered a key economic model to meet the challenge of sustainable development. Strenous efforts are focused on the transformation of waste into resources that can be reintroduced into the economic system through proper management. In this way, the linear and waste-producing value chain problems are solved, making them circular, and more sustainable solutions are proposed in those chains already benefiting from circular processes, so that waste generation and waste are reduced on the one hand, and on the other, the non-efficient consumption of resources decreases. In the face of this current tide, there is another option that proposes a certain nuance, based on the premise that, although circular systems promote sustainability, it does not mean that they are in themselves sustainable, given that, in the first place, the effects of CE on sustainable development are not fully known and, on the other hand, the CE model includes the flow of materials, with only scant consideration of the flow of non-material resources (water, soil and energy). -
