The internal water footprint of South African consumption is mainly due to the consumption of agricultural products followed by domestic water supply and industrial products. The external water footprint is largely due to the import of agricultural products for domestic consumption and, to a smaller extent, due to the import of industrial products. It is interesting to note that the ratio of external to total water footprint of consumption is higher for industrial products (74%) than for agricultural products (22%). However, this not surprising, as SA imports the majority of its capital equipment and this practice has been growing at a faster rate than commodity imports (Edwards and Lawrence, 2006). For the agricultural sector, the ratio of the external to the total water footprint is significantly higher for the green-water footprint (20%) than for the blue (1%) or the grey-water footprint (1%). For the industrial sector, the external blue-water footprint to total industrial water footprint ratio is 6%, whereas this figure for the grey component is 67%. About 78% of the water footprint of South African national consumption is internal and 22% is external (Table 5). Hence about one fifth of the water resources consumed or polluted to make all products consumed by South African citizens are located outside of the country (see Figs 3 and 4).
