Consumptive water footprint and economic green and blue-water productivity (EWP) of the 20 crops with the highest total water footprint produced in South Africa, plus the most important livestock products. Note that fodder crops do not have an economic water productivity. Therefore oats, which ranks 21st with respect to the total water footprint of production, has been added. Data are averaged for the time period 1996–2005. (Own elaboration based on Mekonnen and Hoekstra (2010a) and FAO (2014)
