Figure 7 shows the total consumptive (green- and blue-) water footprints and the economic green- and blue-water productivity of the major crop and livestock products in SA. Grapes, potatoes, green maize, apples, pears, and oranges have a relatively high economic green and blue-water productivity, while at the same time their consumptive water footprint is relatively low compared to other crops that are considered here. In particular seed cotton and oats have a large share of the blue-water footprint of production to total consumptive water footprint, with less economic water productivity than most other crops. Meat products do have a large consumptive water footprint overall,for which the main portion is green water. Their economic water
productivities do not rank particularly high.
