Available in PDF, EPUB and Kindle. Book excerpt: Face aux changements globaux et aux défis du développement soutenable, l'approvisionnement alimentaire urbain doit à la fois être analysé à travers les processus qui le sous-tendent et quantifié en termes de mobilisation des ressources naturelles et d'émission des polluants dans l'environnement. On s'est intéressé dans le cadre de cette thèse à comprendre le mécanisme d'approvisionnement en viande et en lait frais de l'agglomération parisienne sur une période longue de deux siècles et à déterminer, produit par produit, l'empreinte environnementale de l'approvisionnement en termes d'emprise spatiale, de mobilisation d'eau et de flux d'azote entre les agro-systèmes et l'environnement au début des XIXe, XXe et XXIe siècles. On a utilisé des données statistiques nationales et internationales de transport et de production agricole pour déterminer et suivre l'évolution de l'aire géographique d'approvisionnement, évaluer la fraction des subsistances régionales que réclame la capitale pour son approvisionnement, reconstituer à l'aide des modèles de rationnement et des tables d'alimentation les rations des animaux approvisionnant Paris, déterminer, en termes à la fois de biomasse, d'énergie et de protéines, le rendement en viande et en lait du fourrage aux différentes dates et enfin calculer, de manière spatialisée, l'étendue des terres agricoles (empreinte spatiale) - et les flux d'azote et d'eau impliqués dans la production. L'empreinte hydrique a pour objectif de mesurer le volume des prélèvements d'eau (pluviale et d'irrigation) et le taux moyen de mobilisation des apports d'origine pluviale. L'empreinte azotée brute désigne le tonnage total d'azote mis en jeu dans la production, dont le partage entre la production d'aliments et les pertes environnementales dépend de la manière dont fonctionnent les agro-systèmes et caractérise la profondeur de l'empreinte urbaine. On propose ainsi d'élargir la notion d'équivalent habitant (Equ/Hab) classiquement considéré comme représentatif des émissions individuelles d'azote dans les eaux usées urbaines et de définir un équivalent habitant amont qui englobe en quelque sorte tous les rejets individuels d'azote en amont de la ville, relatifs à la production de la nourriture d'un citadin. Depuis le début du XIXe siècle, l'étendue de production par habitant s'est réduite d'un facteur six (pour une consommation de viande et de lait égale à environ 2 kg N/hab/an au début du XIXe siècle comme actuellement) - la réduction étant pour 30 % environ relative au doublement du rendement en viande et en lait du fourrage - mais l'intensité d'utilisation de l'eau et la profondeur de l'empreinte par hectare ont respectivement doublé et quadruplé. On estime qu'actuellement, 45 % des pertes d'azote - soit 5,1 kg N/hab/an ou 60 kg N/ha - proviennent des fumures laissées à l'abandon, faute de n'être reconduites à l'agriculture végétale. Etant donné que la somme des importations de viande bovine, porcine et de lait représente 25 % de l'apport protéique total dans l'alimentation du Parisien et sachant que la fraction végétale de l'alimentation est à priori caractérisée par moins de pertes d'azote que la fraction animale, on estime l'équivalent habitant amont de l'ensemble de l'alimentation du Parisien, à environ 7 Equ/Hab.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, interest for local energy production, supply and consumption has increased in academic and public debates. In particular, contemporary energy transition discourses and strategies often emphasize the search for increased local energy autonomy, a phrase which can refer to a diverse range of configurations, both in terms of the spaces and scales of the local territory considered and in terms of what is meant by energy autonomy. This book explores policies, projects and processes aimed at increased local energy autonomy, with a particular focus on their spatial, infrastructural and political dimensions. In doing so, the authors – Sabine Barles, Bruno Barroca, Guilhem Blanchard, Benoit Boutaud, Arwen Colell, Gilles Debizet, Ariane Debourdeau, Laure Dobigny, Florian Dupont, Zélia Hampikian, Sylvy Jaglin, Allan Jones, Raphael Ménard, Alain Nadaï, Angela Pohlmann, Cyril Roger-Lacan, Eric Vidalenc – improve our understanding of the always partial and controversial processes of energy relocation that articulate forms of local metabolic self-sufficiency, socio-technical decentralization and political empowerment. Comprising fifteen chapters, the book is divided into four parts: Governance and Actors; Urban Projects and Energy Systems; Energy Communities; and The Challenges of Energy Autonomy.

Book excerpt: What do we mean when we say that cities have altered humanity’s interaction with nature? The more people are living in cities, the more nature is said to be "urbanizing": turned into a resource, mobilized over long distances, controlled, transformed and then striking back with a vengeance as "natural disaster". Confronting insights derived from Environmental History, Science and Technology Studies or Political Ecology, Urbanizing Nature aims to counter teleological perspectives on the birth of modern "urban nature" as a uniform and linear process, showing how new technological schemes, new actors and new definitions of nature emerged in cities from the sixteenth to the twentieth century.

Available in PDF, EPUB and Kindle. Book excerpt: In the same realm as social ecology, industrial ecology and the circular economy, a new interdisciplinary field is growing: territorial ecology. Based on the analysis of the metabolism of human societies at a local level, it helps us diagnose a socioecosystem. This diagnostic is not only based on what is circulating, but also on how it is organized and why. Who is at the origin of a flow? What are their motivations? Who has the power to make decisions about it? This methodology, taking into account both the material description of human societies and the analysis of decisionmaking processes, might also be relevant for territorial diagnostics. It leads us to a systemic view of the consequences of individual and collective actions on the sustainability of local socio ecosystems. Socio-ecological transition implies a substantial evolution of human societies. Innovation, be it technological, organizational or social, is intrinsically involved in this evolution. However, if transition calls for disruptive rather than incremental innovations, we must also assess these innovations with a systemic view of their consequences.

Available in PDF, EPUB and Kindle. Book excerpt: The global food crisis is a stark reminder of the fragility of the global food system. The Global Food Crisis: Governance Challenges and Opportunities captures the debate about how to go forward and examines the implications of the crisis for food security in the world’s poorest countries, both for the global environment and for the global rules and institutions that govern food and agriculture. In this volume, policy-makers and scholars assess the causes and consequences of the most recent food price volatility and examine the associated governance challenges and opportunities, including short-term emergency responses, the ecological dimensions of the crisis, and the longer-term goal of building sustainable global food systems. The recommendations include vastly increasing public investment in small-farm agriculture; reforming global food aid and food research institutions; establishing fairer international agricultural trade rules; promoting sustainable agricultural methods; placing agriculture higher on the post-Kyoto climate change agenda; revamping biofuel policies; and enhancing international agricultural policy-making.

Available in PDF, EPUB and Kindle. Book excerpt: As western-style food systems extend further around the world, food sustainability is becoming an increasingly important issue. Such systems are not sustainable in terms of their consumption of resources, their impact on ecosystems or their effect on health and social inequality. From 2009 to 2011, the duALIne project, led by INRA and CIRAD, assembled a team of experts to investigate food systems downstream of the farm, from the farm gate, to consumption and the disposal of waste. Representing a diverse range of backgrounds spanning academia and the public and private sectors, the project aimed to review the international literature and identify major gaps in our knowledge. This book brings together its key conclusions and insights, presenting state-of-the-art research in food sustainability and identifying priority areas for further study. It will provide a valuable resource for researchers, decision-makers and stakeholders in the food industry.

Book excerpt: Risk analysis is widely recognised as the fundamental methodology underlying the development of food safety standards. As recognised in the 1995 consultation, risk analysis is composed of three separate but integrated elements, namely risk assessment, risk management and risk communication. That consultation recognised risk communication as an interactive process of exchange of information and opinion on risk among risk assessors, risk managers, and other interested parties. Risk management is defined within Codex as the process of weighing policy alternatives in the light of the results of risk assessment and, if required, selecting and implementing appropriate control options, including regulatory measures. The outcome of the risk management process, as undertaken by Committees within the Codex Alimentarius system, is the development of standards, guidelines and other recommendations for food safety, m the national situation it is likely that different risk management decisions could be made according to different criteria and different ranges of risk management options. The overall objective of Codex is to ensure consumer protection and to facilitate international trade.

Available in PDF, EPUB and Kindle. Book excerpt: Water has always been a source of risks and opportunities in the Middle East and North Africa. Yet rapidly changing socioeconomic, political, and environmental conditions make water security a different, and more urgent, challenge than ever before. This report shows that achieving water security means much more than coping with water scarcity. It means managing water resources in a sustainable, efficient, and equitable way. It also involves delivering water services reliably and affordably, to reinforce relationships between service providers and water users and contribute to a renewed social contract. Water security also entails mitigating water-related risks such as floods and droughts. Water security is an urgent target, but it is also a target within reach. A host of potential solutions to the region’s water management challenges exist. To make these solutions work, clear incentives are needed to change the way water is managed, conserved, and allocated. To make these solutions work, countries in the region will also need to better engage water users, civil society, and youth. The failure of policies to address water challenges can have severe impacts on people’s well-being and political stability. The strategic question for the region is whether countries will act with foresight and resolve to strengthen water security, or whether they will wait to react to the inevitable disruptions of water crises.

This book was released on 2012-03-30 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over half the world's population now deemed to be urbanised, cities are assuming a larger role in political debates about the security and sustainability of the global food system. Hence, planning for sustainable food production and consumption is becoming an increasingly important issue for planners, policymakers, designers, farmers, suppliers, activists, business and scientists alike. The rapid growth of the food planning movement owes much to the fact that food, because of its unique, multi-functional character, helps to bring people together from all walks of life. In the wider contexts of global climate change, resource depletion, a burgeoning world population, competing food production systems and diet-related public health concerns, new paradigms for urban and regional planning capable of supporting sustainable and equitable food systems are urgently needed. This book addresses this urgent need. By working at a range of scales and with a variety of practical and theoretical models, this book reviews and elaborates definitions of sustainable food systems, and begins to define ways of achieving them. To this end 4 different themes have been defined as entry-points into the discussion of 'sustainable food planning'. These are (1) urban agriculture, (2) integrating health, environment and society, (3) food in urban design and planning and (4) urban food governance.
