As a response, it is increasingly recommended that efforts should focus on improving water productivity in agriculture, and significant public and private investments are being made with this goal in mind. Yet most public communications are vague on the meaning of agricultural water productivity, and on what should be done to improve it. They also tend to emphasize water as if it were the only input that mattered. This paper presents findings from a first attempt to survey the agricultural productivity and efficiency literature with regard to the explicit inclusion of water aspects in productivity and efficiency measurements, with the aim of contributing to the discussion on how to assess and possibly improve agricultural water productivity. The focus is on studies applying single-factor productivity measures, total factor productivity indices, frontier models, and deductive models that incorporate water. A key finding is that most studies either incorporate field- and basin-level aspects but focus only on a single input (water), or they apply a multi-factor approach but do not tackle the basin level. It seems that no study on agricultural water productivity has yet presented an approach that accounts for multiple inputs and basin-level issues. However, deductive methods do provide the flexibility to overcome many of the limitations of the other methods.en-USCC BY 3.0 IGOACCESS TO WATERACTUAL EVAPOTRANSPIRATIONAGRICULTURAL ACTIVITIESAGRICULTURAL ECONOMYAGRICULTURAL PRODUCTIONAGRICULTURAL WATERAGRICULTURAL WATER USEAGRICULTURE WATERAQUIFERAVAILABLE WATERBASINSCALIBRATIONCANALSCATCHMENTCLIMATE CHANGECLIMATIC CONDITIONSCOLLECTIVE ACTIONSCOMPETITION FOR WATERCONJUNCTIVE USECONSUMPTIVE USECOST OF WATERCOVERINGCROP PRODUCTIONCROP YIELDSCUBIC METERSDEMAND MANAGEMENTDOWNSTREAM USERSDRAINAGEDRIP IRRIGATIONENGINEERINGENVIRONMENTAL QUALITYEROSIONEVAPORATIONEVAPOTRANSPIRATIONEXPORTFARM MANAGEMENTFARMERSFARMINGFLOW WATERFOOD PRODUCTIONFOOD SECURITYFRESHWATERGLOBAL WATER CRISISGLOBAL WATER PARTNERSHIPGRAVITYGROUNDWATERHYDROGEOLOGYHYDROLOGIC CYCLEHYDROLOGYINTERNATIONAL WATERIRRIGATIONIRRIGATION CANALSIRRIGATION DEVELOPMENTIRRIGATION DISTRICTIRRIGATION SYSTEMSIRRIGATION TECHNOLOGYIRRIGATION WATERMEASUREMENTSMOISTURE CONTENTNATURAL RESOURCESOASESON-FARM WATER MANAGEMENTOWNERSHIP OF WATERPIPELINESPOLLUTIONPOPULATION GROWTHPRESSUREPRICE OF WATERPRODUCTION PROCESSPROGRAMSQUANTITIES OF WATERQUANTITY OF WATERRAINRAINFALLREGIONAL WATER RESOURCESREMOTE SENSINGRIVER FLOWROOT ZONERUNOFFSALINITYSEEPAGESOIL MANAGEMENTSOIL MOISTURESURFACE RUNOFFSURFACE WATERSURFACE WATER QUALITYSUSTAINABLE USETRANSPIRATIONUSE OF WATERWATER ALLOCATIONWATER ANALYSISWATER APPLICATIONWATER AVAILABILITYWATER BUDGETSWATER CONSUMPTIONWATER DEMANDWATER DEMAND MANAGEMENTWATER DEVELOPMENTWATER LOSSESWATER MANAGEMENTWATER NEEDSWATER PARTNERSHIPWATER QUALITYWATER QUANTITYWATER RESOURCEWATER RESOURCESWATER RIGHTSWATER SAVINGSWATER SCARCITYWATER SHORTAGESWATER SOURCEWATER STORAGEWATER STRATEGYWATER SUPPLIESWATER SUPPLYWATER TRANSFERSWATER USEWATER USERSWATER USESWATER WITHDRAWALSHow to Assess Agricultural Water Productivity?
