Soils of the Sahelian region, in the broad sense, between 200 and 1200 mm of annual rainfall, are overexploited and therefore degraded. Soil and water conservation measures have to be taken against this degradation. These measures can consist in soil tillage, implementation of permanent structures or use of vegetation. From the experience of earlier or on-going implementation and research, the most commonly applied techniques in the Sahel are described and compared with regard to: The climate, soil and topography to which they can be applied; their impact on agricultural yields and erosion control; their costs: materials and labor needed for construction; specific bottle necks for construction: know-how, equipment, organization, etc. Constraints related to the implementation, the maintenance and the replicability of the soil and water conservation devices are considered from a general point of view: support coming from the projects, importance of the intensification of the farming system, development and management of village territory.
