The agriculture sector is typical. Various infrastructures would affect agriculture growth differently depending on the type of commodity. This paper finds that a general transport network is essential to promote coffee and cocoa production, perhaps along with irrigation facilities, depending on local rainfall. Conversely, along with the transport network, the dairy industry necessitates rural water supply services as well. In some African countries, a 1 percent improvement in these key aspects of infrastructure could raise GDP by about 0.1-0.4 percent, and by possibly by several percent in some cases.CC BY 3.0 IGOACCESSIBILITYAGRICULTURAL ACTIVITIESAGRICULTURAL COMMODITIESAGRICULTURAL DEVELOPMENTAGRICULTURAL ECONOMICSAGRICULTURAL EXPORTSAGRICULTURAL GROWTHAGRICULTURAL LABORAGRICULTURAL MARKETINGAGRICULTURAL OUTPUTAGRICULTURAL PRODUCTIONAGRICULTURAL PRODUCTIVITYAGRICULTURAL PRODUCTSAGRICULTURAL RESEARCHAGRICULTUREARBITRAGEBANANASBARLEYBEEFBEERCACANNINGCAPITAL INVESTMENTCASHEW NUTSCASSAVACEREALSCHEESECHOCOLATECIGARETTESCLOVESCOCOACOCOA BEANSCOCOA BUTTERCOCOA INDUSTRIESCOFFEECOFFEE EXPORTSCOFFEE PRODUCTIONCOFFEE SUBSTITUTESCOMMODITYCOMPETITIVENESSCONSUMER PREFERENCESCONSUMERSCOOPERATIVESCOTTONCOTTONSEEDCREAMCROPLANDCROPSDAIRYDAIRY DEVELOPMENTDAIRY INDUSTRYDAIRY PRODUCTIONDAIRY PRODUCTSDAIRY SECTORDEMAND ELASTICITYDEVELOPMENT STRATEGIESDIVIDENDSDRIVERSECONOMETRICSECONOMIC EFFICIENCYECONOMIC PERFORMANCEECONOMICS LITERATUREECONOMIES OF SCALEEFFICIENT TRANSPORTELASTICITYENDOGENOUS VARIABLESEXPORTSFARMFARMERSFARMINGFARMSFLOURFOOD POLICYFOOD POLICY RESEARCHFOOD STAPLESFRUITFRUITSGDPGRAINSGROUNDNUTSGROWTH IN AGRICULTUREGROWTH RATEHUMAN CAPITALINCOME DISTRIBUTIONINCOME GENERATIONINFRASTRUCTURE DEVELOPMENTINFRASTRUCTURE INVESTMENTINFRASTRUCTURE INVESTMENTSINFRASTRUCTURESINTERNATIONAL FOOD POLICY RESEARCH INSTITUTEINTERNATIONAL TRADELABOR FORCELABOR MARKETSLINSEEDLIVESTOCKLIVESTOCK PRODUCTSMAIZEMANGOESMARGINAL COSTMEATMILLETNATIONAL INCOMENATURAL RUBBEROIL PALMONIONSORANGESPADDYPALM OILPAPAYASPERISHABILITYPINEAPPLESPLANTAINSPOTATOESPRICE ELASTICITIESPRICE ELASTICITYPRODUCEPRODUCTION COSTSPRODUCTION EFFICIENCYPRODUCTION FUNCTIONPRODUCTION TECHNOLOGIESPUBLIC ROADPUBLIC SERVICESQUALITY OF TRANSPORTR&DRARAILWAYSRICEROADROAD IMPROVEMENTROAD NETWORKROADSROOT CROPSRURAL DEVELOPMENTRURAL INFRASTRUCTURERURAL ROADSSEEDSEED COTTONSESAMESIDE EFFECTSSILKSMALL FARMERSORGHUMSPRINGSUB-SAHARAN AFRICASUGARSUGAR CANESWEET POTATOESTAROTEATELECOMMUNICATIONSTEXTILESTOBACCOTOMATOESTOTAL FACTOR PRODUCTIVITYTOTAL FACTOR PRODUCTIVITY GROWTHTRADE BARRIERSTRADITIONAL ECONOMIESTRANSPORTTRANSPORT COSTSTRANSPORT INFRASTRUCTURETRANSPORT INFRASTRUCTURESTRANSPORT NETWORKTRANSPORTATIONTRUEUNDERESTIMATESUTILITY FUNCTIONVALUATIONVALUE ADDEDVANILLAVEALVEHICLEWATER SUPPLYWHEATWORLD TRADE ORGANIZATIONWTOYAMYAMSYIELDSWorld Bank10.1596/1813-9450-4411
