The present study proposes a methodology for design and implementation of low-cost runoff water harvesting basins, using an approach based on community mutual aid. Soil structure has a strong influence on the need for labour for excavation, waterproofing, and choice of materials for stabilization of the walls. Excavation must be made immediately after the harvest season, when the weather is relatively mild, the soil is still moist enough, and food is not a limiting factor.application/pdfenRAINFED FARMINGDRY SPELLSWATER HARVESTINGSUPPLEMENTAL IRRIGATIONFOOD SECURITYBURKINA FASORUNOFF WATERSAHELCLIMATE CHANGE ADAPTATIONJournal Article
