Successful small-scale irrigation in the Sahel

This study reviews the experience with irrigation projects in Africa with particular attention to small-scale irrigation in the Sahel, where small-scale private irrigation systems, based on simple, low-cost technologies, are expanding successfully in a number of countries. It examines the characteristics of the successful projects in order to determine the basis for future successful project design. It then outlines those factors most critical to project success, including full and early farmer participation, low-cost technologies, an adequate financial return that provides a cash flow to farmers at the time that they need it, and sustainability through groundwater surveys and attention to environmental considerations.
