Processus et enjeux d'eau en Afrique de l'Ouest soudano-sahélienne

Book Description
Ce livre décrit les processus hydrologiques et leurs dynamiques passées et actuelles au gré de l’évolution des agrosystèmes, de leur emprise spatiale, de leur capacité d’adaptation au changement global, et aux changements climatiques. Il se fonde sur l’indicateur que représente la capacité de rétention en eau des sols, qui conditionne la bonne alimentation en eau et en nutriments des systèmes racinaires, tant des cultures que de la végétation naturelle. C’est aussi cette rétention en eau qui permet de limiter le ruissellement et les inondations en aval. Parti d’une réflexion sur le paradoxe hydrologique du Sahel (la hausse des écoulements observée dans cette région durant la sécheresse), l’ouvrage décrit les enjeux de ces évolutions spatio-temporelles et entend montrer que la pression démographique n’est pas forcément un facteur de dégradation des agrosystèmes; au contraire, les régions les plus densément peuplées à l’heure actuelle sont très souvent celles qui font preuve de la plus grande capacité de résilience et d’adaptation aux changements climatiques et environnementaux.
Une évaluation des resources du climat et de l'eau pour le développement de l'agriculture dans la zone soudano-sahélienne de l'Afrique de l'Ouest

Book Description
Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
Climate Prediction and Agriculture

Book Description
Based on an International Workshop held in Geneva in 2005, this book reviews the advances made so far in seasonal climate predictions and their applications for management and decision-making in agriculture. It also identifies the challenges to be addressed in the next 5 to 10 years to further enhance operational applications of climate predictions in agriculture, especially in developing countries.
Tropical Extremes

Languages : en
Pages : 366
Book Description
Tropical Extremes: Natural Variability and Trends features the most up-to-date information on present and future trends related to climate change and tropical extremes. Including contributions from the foremost experts in the field, this important reference addresses the science behind climate change and natural variability in relation to tropical extremes. The book also includes practical insight into modeling and observation approaches. In a warming world, the increase of weather extremes presents a scientifically complex and societally relevant challenge. The book confronts these challenges with observational evidence, modeling studies and expected impacts. This is an essential reference for researchers, modelers and students in the fields of climate and atmospheric science looking to better understand the causes and effects of tropical extremes and natural variability. - Illuminates the role of natural variability and climate change in determining the fate and state of tropical extremes - Offers a robust guide for analysis relating to the impacts of extremes, thus providing a potential roadmap for navigating the future of risk analysis and the water-food-energy nexus - Edited by a diverse team of global experts - Includes contributions from leading researchers in the field, comprising the most up-to-date understanding of tropical extremes
