Note générale :	The need to understand the technical and socioeconomic constraints in irrigation management for diversified cropping underlies this study. The main constraints identified include the unreliability and inequity of supply at the secondary and tertiary levels of the irrigation system, the lak of organization and management for sharing water below the secondary level, and the pour communication between agency staff and farmers in water delivery acheduling. Intervention studies have shown that flow measurements combined with regulary scheduled rorations and regular meetings between agency staff and farmers can enhance the management capacity of both. Because of the grater economic risks faced by farmers in growing non-rice crops as compared with rice, an assured market and a competitive price are indispensable for promoting diversified cropping.
