The authors find that adequate irrigation, chemical fertilizer, and labor inputs are the key to high productivity. Chemical fertilizer is expensive in Uganda and Mozambique and is barely used. This is aggravated when water access is limited because of the complementarities between fertilizer and irrigation. Meanwhile, in the schemes located in four countries in West Africa's Sahel region, where water access is generally good and institutional support for chemical fertilizer exists, rice farmers achieve attractive yields. Some countries' wage rate is high and thus mechanization could be one solution for this constraint. Improvement of credit access also facilitates the purchase of expensive fertilizer or the employment of hired labor.CC BY 3.0 IGOACCESS TO IRRIGATIONACCESS TO WATERAGRICULTURAL DEVELOPMENTAGRICULTURAL WATERAGRONOMYANNUAL RAINFALLAVERAGE YIELDSCANALSCLIMATIC CONDITIONSCONSTRUCTIONCREDIT ACCESSCREDIT PROGRAMCROPCROP MANAGEMENTCROP MANAGEMENT PRACTICESCULTIVATED AREACULTIVATED RICECULTIVATION PRACTICESDAILY WAGEDAMDEVELOPING REGIONSDRY LANDEXTENSION AGENCYFAOFARMFARM MANAGEMENTFARM SIZEFARMERFARMER ORGANIZATIONSFARMERSFARMINGFARMING PRACTICESFERTILIZERFERTILIZER SUBSIDYFERTILIZER USEFOOD POLICYFOOD SECURITYGERMPLASMGRAINGRAIN QUALITYGRAVITYGRAVITY IRRIGATIONGREEN REVOLUTIONHARVESTINGHOUSEHOLD HEADHOUSEHOLD SIZEHUMAN CAPITALINCOME DISTRIBUTIONINLAND VALLEY BOTTOMSINTERNATIONAL FOOD POLICY RESEARCH INSTITUTEINTERNATIONAL RICE RESEARCH INSTITUTEIRRIIRRIGATIONIRRIGATION AREAIRRIGATION DEVELOPMENTIRRIGATION INVESTMENTSIRRIGATION MANAGEMENTIRRIGATION PROJECTSIRRIGATION SCHEMEIRRIGATION SCHEMESIRRIGATION SYSTEMIRRIGATION WATERLABOR DEMANDLANDLESS HOUSEHOLDSLOCAL FARMERSMICRO-FINANCEMICRO-FINANCE INSTITUTIONSPADDYPADDY YIELDSPESTICIDEPOVERTY REDUCTIONPRODUCTION COSTPRODUCTION TECHNOLOGYPUMPINGRAINFALLRAINFED AREASRICERICE CULTIVATIONRICE PRICERICE PRICESRICE PRODUCTIONRICE RESEARCHRICE VARIETIESRIVER VALLEYRURAL DEVELOPMENTSCHOOLINGSEEDSEEDINGSMALL FARMERSSMALL-SCALE IRRIGATIONSOIL FERTILITYTRANSPLANTINGTROPICAL AGRICULTUREWATER DELIVERYWATER DELIVERY SYSTEMSWATER DISTRIBUTIONWATER HARVESTINGWATER SHORTAGEWATER SUPPLYWETLANDSYIELDSWorld Bank10.1596/1813-9450-5560
