Gestion intégrée des ressources naturelles en zones inondables tropicales


Book Description

De par leur richesse en ressources naturelles renouvelables, les zones inondables tropicales revêtent un intérêt social et économique majeur pour les pays en développement. Cependant, les fleuves tropicaux sont aujourd'hui de plus en plus aménagés pour satisfaire les besoins liés à de nouvelles activités. Les zones jusque-là régulièrement inondées par la crue annuelle se réduisent ou alors les rythmes de leur inondation sont profondément modifiés. Les impacts de tels changements sont nombreux




Gestion intégrée des ressources naturelles en zones inondables tropicales


Book Description

De par leur richesse en ressources naturelles renouvelables, les zones inondables tropicales revêtent un intérêt social et économique majeur pour les pays en développement. Cependant, les fleuves tropicaux sont aujourd'hui de plus en plus aménagés pour satisfaire les besoins liés à de nouvelles activités. Les zones jusque-là régulièrement inondées par la crue annuelle se réduisent ou alors les rythmes de leur inondation sont profondément modifiés. Les impacts de tels changements sont nombreux et portent atteinte à la biodiversité et à la durabilité des systèmes d'exploitation. Il s'avère alors nécessaire de définir de nouvelles approches de la gestion de l'eau, des espaces et des ressources vivantes, qui tout à la fois préservent les écosystèmes et prennent en considération les besoins des différents usagers. Tel est l'objectif de cet ouvrage qui pose, dans un premier temps, la problématique sociétale autour de laquelle cette gestion doit être repensée, en faisant apparaître la diversité d'acteurs et d'institutions concernés. Il présente ensuite les acquis les plus récents de la recherche sur le fonctionnement de ces écosystèmes ainsi que sur les pratiques et stratégies déployées par les populations qui les exploitent. Enfin est abordée la question des instruments à mettre en place pour assurer l'effectivité d'une gestion durable des zones inondables tropicales : après avoir fait le point sur les apports de la recherche concernant les outils de traitement et de partage de l'information environnementale, l'ouvrage se termine par un débat sur les conditions de création et de fonctionnement des institutions de suivi, de concertation et de décision.




Les ailes du Sahel


Book Description

'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa? Winner of the BB/BTO Best Bird Book Award 2010 The Jury commented: "It is a tremendous book in every department. It marks a step-change in our knowledge of the ecology of this critically important region in the European-African migration system and of the many species (familiar to us on their breeding grounds) that winter there. The authors combine the latest scientific information with vivid descriptions of landscapes and animals. Their book is richly illustrated with large numbers of drawings, maps and photographs by acclaimed experts. The wealth of coloured graphics has been particularly well thought out and encourages readers to delve into the figures and learn more about the region, rather than having the (all-too-common) opposite effect. Summing up, the jury praises not just the high quality of the texts, the information and the illustrations, but also the sheer pleasure of reading the book: "One of the key attributes of a good book is to be able to grip the reader's attention and transport him or her to another place. We feel confident that [Living on the edge] will have that effect."




River Basin Management


Book Description

River Basin Management – Under a Changing Climate is a collection of relevant research, experiments, and case study chapters. This book offers a comprehensive overview of recent developments in water resources planning, monitoring, and management using in situ measurements, modeling, and community participation. The book includes five sections and fourteen chapters that discuss water resources management, focusing on river basins, which includes quantifying water resources, evaluating water quality, and evaluating the impact of hydraulic structures on water resources management. Chapters also discuss the critical role of community/stakeholders in water resources, planning, monitoring, conservation, and management at smaller to larger river basins.




The World's Largest Wetlands


Book Description

This volume presents the views of leading experts on each of the world's largest wetland systems. This international team of authors share their understanding of the ecological dynamics of large wetlands and their significance, and emphasise their need of conservation.

Groundwater Pollution in Africa


Book Description

In 2000, various UN organizations launched a collaborative effort to assess the vulnerability of groundwater in several African cities. The project addressed the issue of aquifer vulnerability and the protection of groundwater quality. This book is a collection of thirty peer-reviewed papers on the topic, and provides a glimpse of the situation acr




Heritage Regimes and the State


Book Description

What happens when UNESCO heritage conventions are ratified by a state? How do UNESCO’s global efforts interact with preexisting local, regional and state efforts to conserve or promote culture? What new institutions emerge to address the mandate? The contributors to this volume focus on the work of translation and interpretation that ensues once heritage conventions are ratified and implemented. With seventeen case studies from Europe, Africa, the Caribbean and China, the volume provides comparative evidence for the divergent heritage regimes generated in states that differ in history and political organization. The cases illustrate how UNESCO’s aspiration to honor and celebrate cultural diversity diversifies itself. The very effort to adopt a global heritage regime forces myriad adaptations to particular state and interstate modalities of building and managing heritage.




The Niger River Basin


Book Description

The Niger River Basin, home to 100 million people, is a vital yet complex asset for West and Central Africa. It is the continent's third largest river basin, traversing nine countries -Benin, Burkina Faso, Cameroon, Chad, C©þte d'Ivoire, Guinea, Mali, Niger, and Nigeria. The River embodies both these nations' livelihoods and their geopolitics. It is not simply water but rather an origin of identity, a route for migration and commerce, a source of conflict, and a catalyst for cooperation. Cooperation among decision-makers and users is crucial to address the threats to water resources. The Niger.
