Les interactions entre sociétés humaines et environnement constituent un défi majeur pour l’avenir de la planète. Les conférences internationales (Rio, Kyoto, Johannesburg, etc.) montrent toute l’ambiguïté et tous les enjeux économiques et politiques nationaux qui s’y expriment. Dans ce contexte hautement politique, comment créer des convergences qui répondent aux besoins des populations et à une gestion environnementale appropriée ? C’est bien là toute la difficulté du développement durable. L’une des réponses qu’apporte ce livre passe par la nécessité de renouveler en profondeur les problématiques scientifiques et par l’importance de développer des études au niveau local ; car c’est là où se trouvent confrontées les stratégies des sociétés et les réponses qu’elles apportent aux multiples contraintes auxquelles elles ont à faire face. Connaître et faire connaître, dans les processus de prise de décision, les capacités d’adaptation et d’innovation des sociétés locales, cerner de nouveaux modes de régulation pour l’usage des ressources naturelles, proposer des stratégies alternatives de développement durable : tels sont les enjeux fondamentaux des études développées dans ce livre, à partir d’exemples contrastés pris dans la zone bioclimatique méditerranéenne.

This book attempts to describe runoff, infiltration and subsurface flow of water by adopting a holistic approach rather than restricting itself to a particular section of the hydrological cycle. It includes reports on recent studies which have led to a better understanding of a variety of problems prevailing in semi-arid and arid zones. Emphasis has been put on studies which incorporate the use of advanced applied techniques developed for dealing with these water problems. This has been done with the hope of providing guidance in solving special problems of water supply and safe reuse of wastes, liable to arise during future development in these zones. Audience: This volume is of value for experts from academia, consultancies and water resources planning and management institutes interested in hydrological problems in semi-arid and arid regions.
