Apractical research-and-action program has been led on five représentative bottomland sites in the Sahel. Aiming to gain a better knowledge of how they function under natural conditions and the problems currently being encountered, and to identify appropriate water management structures and techniques. THe sites concerned are in the Sine Saloum and Casamance in Senegal, in southern Mali, and in Yatenga and Comoe in Burkina Faso.
This research has provided an opportunity to design, develop and test new measuring instruments, diagnostic tools and water management methods. A bottomland typology has been achieved, leading to several improvedland-management policies.
With techniques for conserving soils and improving their fertility, coupled" with controlled supply of water to the crops, it is now possible to consider moving on from the pilot phase to an integrated development project on larger areas. The determining factors for success or failure in thèse initiatives will then be the socioeconomic processes.
