Crop water productivity
Definition / description
Crop water productivity is defined by Kassam and Smith (2001) at FAO as “Crop yield/Water consumptively used in ET”. It may be quantified in terms of wet or dry yield, nutritional value or economic return. According to Moulden (1997), the productivity of water is defined as “the physical mass of production or the economic value of production measured against gross inflows, net inflow, depleted water, process depleted water, or available water”.
