En Afrique tropicale et dans le bassin béninois de la Volta, de nombreuses études montrent que les eaux de surface sont très tributaires de la variabilité climatique. L'instabilité pluviomérique des années 1960 à nos jours a contribué à une modification des régimes hydrologiques dans le bassin de la Pendjari. Le but de cette étude est la modélisati...
Les changements environnementaux à l’échelle globale peuvent se traduire par une modification des conditions abiotiques et de la diversité biologique. La fonction de production des écosystèmes forestiers a la particularité d'être à la fois soumise à, et régulatrice de ces changements environnementaux. Il apparaît alors primordial de comprendre la m...

An approach to derive relationships for defining land degradation and desertification risk and developing appropriate tools for assessing the effectiveness of the various land management practices using indicators is presented in the present paper. In order to investigate which indicators are most effective in assessing the level of desertification...
Until the 2000s, water resources in Tunisia were managed solely by government bodies without any consultation with water users. At the local level, Commissariats Régionaux de Développement Agricole [Regional Agricultural Development Committees (CRDAs)], which represented the government bodies, managed water resources. The Tunisian Government then d...
L’irrigation de précision est essentielle dans les zones arides et semi-arides confrontées à des réserves en eau limitées. Cela a poussé la communauté scientifique à développer de nouvelles technologies pour le pilotage de l'irrigation permettant de rationaliser les apports en fonction des besoins de la culture vis-à-vis des objectifs de production...

Global and regional climate models (GCM and RCM) are generally biased and cannot be used as forcing variables in ecological impact models without some form of prior bias correction. In this study, we investigated the influence of the bias correction method on drought projections in Mediterranean forests in southern France for the end of the twenty-...
