Soil water crop modeling for decision support in millet-based systems in the Sahel: a challenge

Food insecurity in the Sahelian environment was extensively shown to be a result of low soil fertility and high climate risks. But décisions and recommendations made from the great wealth of research have little been adopted by farmers. Soil water crop models (SWCM) can assist researchers and development actors in this environment if they can appropriately deal with the constraints and mainly farmer's agricultural development goals.
