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 alim...
Understanding the temporal and spatial variability of soil moisture is fundamental for improving the management of water and soil resources on rainfed agrosystems. The present study focused on the soil moisture (SM) patterns observed in a hilly rainfed agrosystem. We analyzed five datasets from measurement at 15 sites during various crop growth cyc...
Climate and environmental changes since the Last Glacial Maximum in the tropical zone of West Africa are usually inferred from marine and continental records. In this study, the potential of carbonate pedo-sedimentary geosystems, i.e. Vertisol relics, to record paleoenvironmental changes in the southwestern part of Chad Basin are investigated. A mu...

La réduction des risques de contamination des eaux de surface et souterraines par les herbicides est un enjeu important en région viticole méditerranéenne du fait de risques élevés liés à l'importance des écoulements de surface et aux usages d'herbicides. L'article présente une méthodologie d'évaluation par modélisation de stratégies d'entretien du...
The transfer of energy and water, as well as gaseous components, in the soil–plant–atmosphere system plays a crucial role in many processes involved in climate change. The surface energy balance drives both evapotranspiration (closely linked to the CO2 flux) and sensible heat flux. By providing direct information on heat dissipation efficiency, sur...
