Book excerpt: Après avoir été longtemps marginalisées, détruites ou dégradées, les zones humides sont aujourd'hui considérées comme un patrimoine précieux qu'il convient de préserver et de restaurer, en raison des multiples fonctions qu'elles remplissent et des bénéfices qui en découlent pour la société. Cet ouvrage collectif a été réalisé par des spécialistes de tous les domaines concernés par les zones humides. Après une introduction sur les enjeux actuels liés aux zones humides, il traite en détail des différentes fonctions de ces milieux : contrôle des crues, flux polluants, maintien de la biodiversité, etc. Les chapitres suivants exposent les avancées récentes en matière d'évaluation économique des services rendus par les zones humides. Enfin, sont exposées les méthodes mises au point pour la protection, la restauration et la création des zones humides. Concertation, recherche et action apparaissent, en conclusion, comme les clés pour la reconquête de ce patrimoine d'importance majeure. Cet ouvrage s'adresse aux ingénieurs, aux responsables d'administration, institutions publiques ou privées, aux associations et aux divers usagers concernés par les questions d'environnement, de gestion de l'eau, d'agriculture et d'équipement. Il sera également une synthèse utile aux chercheurs et aux étudiants

Available in PDF, EPUB and Kindle. Book excerpt: River Restoration River restoration initiatives are now widespread across the world. The research efforts undertaken to support them are increasingly interdisciplinary, focusing on ecological, chemical, physical as well as societal issues. River Restoration: Political, Social, and Economic Perspectives provides a comprehensive overview of research in the field of river restoration in humanities and the social sciences. It illustrates how, in the last thirty years or so, such approaches have evolved and strengthened within the restoration sciences. The scientific community working in this domain has structured itself, often regionally and circumstantially, to critically assess and improve restoration policies and practices. As a research field, river restoration tackles three thematic axes: Human-river interactions – especially perceptions and practices of rivers, and how these interactions can be changed by restoration projects Political processes, with a particular interest in governance and decision-making, and a specific emphasis on the question of public participation in restoration projects Evaluation of the social and economic benefits of river restoration River Restoration: Political, Social, and Economic Perspectives encompasses these three topics, and more, to provide the reader with the most up-to-date and holistic view of this constantly evolving area. The book will be of particular interest to human and social scientists, biophysical scientists (hydrologists, geomorphologists, ecologists), environmental scientists, public policy makers, design or planning officers, and anyone working in the field of river restoration.

Book excerpt: Les actes de ces journées font état de réflexions, tant en France qu'à l'étranger, sur la restauration de marais, d'estuaires, de baies et de lagunes, incluant l'incidence sur les espèces et ressources. L'ouvrage regroupe une sélection des communications présentées devant un public de scientifiques, enseignants, aménageurs professionnels de la mer et conservateurs du littoral. Y sont présentés quelques grands chantiers (lagunes de Venise et de Tunis, baie du Mont-Saint-Michel, estuaire de Seine...), ainsi que des réalisations de tailles et de natures diverses. Des aspects particuliers de la biorestauration sont abordés au travers du traitement biologique des vases, ou celui des pollutions par hydrocarbures. Les aspects technico-économiques s'appuient sur des exemples accidentels ou naturels. Les aménageurs et les sociétés d'ingénierie écologique pourront trouver, dans ces documents, critères et méthodes d'évaluation scientifique pour quantifier les coûts de restauration d'écosystèmes en fonction de l'importance des " dégâts ".

This book was released on 2007-06-14 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mieux connaître le fonctionnement et la valeur intrinsèque des forêts alluviales d'Europe est essentiel pour aider les scientifiques, les naturalistes, les gestionnaires et les décideurs politiques à les préserver dans leur intégralité. L'enjeu est donc à la fois écologique et économique. Si la connaissance des grands fleuves a beaucoup progressé, il n'en reste pas moins que les forêts riveraines sont souvent négligées ou considérées pour leur seule valeur économique. Or, ces écosystèmes restent parmi les plus complexes et les plus riches en espèces de l'Europe, et leur renouvellement dépend étroitement du système pulsé du fleuve. Cet ouvrage est une synthèse des connaissances actuelles sur les forêts alluviales, largement illustré de photos et de schémas. Il s'adresse aux étudiants, aux chercheurs, aux enseignants, aux gestionnaires d'espaces naturels alluviaux, aux associations de protection de la nature et plus généralement à un public désireux de comprendre des écosystèmes exceptionnels.

This book was released on 2003 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's freshwater resources are coming under growing pressure through such environmental hazards as human waste, urbanization, industrialization, and pesticides. The problems are exacerbated through drought in many parts of the world. The improvement of the water quality itself and access to it have been major concerns for politicians and development agencies for over a decade. First officially formulated at the Rio Earth Summit of 1992, they have been restated or expanded since then. The UN Millennium Declaration of 2000 transformed general guidelines into specific targets. The international community pledged "to halve by 2015 the proportion of people who are unable to reach, or to afford, safe drinking water" and "to stop the unsustainable exploitation of water resources, by developing water management strategies at the regional, national and local levels, which promote both equitable access and adequate supplies." Thus, ten years after Rio it is time to take stock. Based on the collective inputs of 23 United Nations agencies and convention secretariats, this Report offers a global overview of the state of the world's freshwater resources. It is part of an on-going assessment process to develop policies and help with their implementation as well as to measure any progress towards achieving sustainable use of water resources. Generously illustrated with more than 25 full-color global maps and numerous figures, the report reviews progress and trends and presents seven pilot case studies of river basins representing various social, economic and environmental settings: Lake Titicaca (Bolivia, Peru); Senegal river basin (Senegal, Mali, Mauritania, Guinea); Seine Normandy (France); Lake Peipsi/Chudskoe (Estonia, Russia); Ruhuna basin (Sri Lanka); Greater Tokyo region (Japan); and Chao Phraya (Thailand). It assesses progress in 11 challenge areas, including health, food, environment, shared water resources, cities, industry, energy, risk management, knowledge, valuing water and governance. Proposing methodologies and indicators for measuring sustainability, it lays the foundations for regular, system-wide monitoring and reporting by the UN, together with the development of standardized methodologies and data. With its comprehensive maps, glossary, references and coverage of a broad range of themes and examples of real-world river basins, the UN World Water Development Report will no doubt prove to be a most valuable reference work. Visit the United Nation's Water Portal for more information on the report and on the International Year of Freshwater 2003.

Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is Africa’s most precious natural resource, providing reliable water supplies for many people. Further development of groundwater resources is fundamental to increasing access to safe water across the continent to meet coverage targets and reduce poverty. There is also an increasing interest in the use of groundwater for irrigated agriculture as the climate becomes more variable. Sustainable development of the resource is not a trivial task and depends crucially on an understanding of the hydrogeology and people with the skills to make informed decisions on how groundwater can best be developed and managed in a sustainable fashion. Despite these obvious needs, however, little attention has been paid to the systematic gathering of information about groundwater resources in the past few decades, with the result that data are patchy, knowledge is limited and investment is poorly targeted. This book was written to start to bridge the knowledge gap. The 29 chapters are written by a combination of practitioners and researchers mainly from within Africa using experience from recent and ongoing projects. The chapters highlight the complexity and variety of issues surrounding the development and management of groundwater resources across Africa, and provide a snapshot of groundwater research and application in the early 21st century. Chapters range from strategic discussions of the role of groundwater in development and poverty reduction, to case studies on techniques used to develop groundwater, and modelling methods for managing groundwater systems.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.

Available in PDF, EPUB and Kindle. Book excerpt: A multi-country research initiative to understand poverty from the eyes of the poor, the Voices of the Poor project was undertaken to inform the World Bank's activities and the upcoming World Development Report 2000/01. The research findings are being published in three books: "Can Anyone Hear Us?" gathers the voices of over 40,000 poor women and men in 50 countries from the World Bank's participatory poverty assessments (Deepa Narayan, Raj Patel, Kai Schafft, Anne Rademacher, and Sarah Koch-Schulte, authors). "Crying Out for Change" pulls together new field work conducted in 1999 in 23 countries (Deepa Narayan, Robert Chambers, Meera Shah, and Patti Petesch, authors). "From Many Lands" offers regional patterns and country case-studies (Deepa Narayan and Patti Petesch, editors). Voices of the Poor marks the first time such an exercise has been undertaken in so many developing countries and transition economies around the world. It provides a unique and detailed picture of the life of the poor and explains the constraints poor people face to escape from poverty in a way that more traditional survey techniques do not capture well. Each of the three volumes demonstrates the importance of voice and power in poor people's definition of poverty. Voices of the Poor concludes that we need to expand our conventional views of poverty which focus on income expenditure, education, and health to include measures of voice and empowerment.
