Blue water consumption on irrigated cropland (mm yr–1 per cropland area, 1971–2000 average).

DescriptionBlue Water Consumption on Cropland

Blue water consumption in agricultural is restricted to irrigated areas. Highest consumption rates occur in warm regions including, for example, northern India and southeast Asia.


Highest blue water consumption rates occur in warm regions where green water (stemming directly from precipitation) is not sufficient to sustain optimal crop growth and where enough blue water is available to fulfill the resulting irrigation water requirements of the crops. Note that the values refer to cropland areas rather than to entire 0.5° grid cells, i.e. the influence of the fractional coverage of a grid cell with cropland is eliminated.

The dataset has been produced within the project “Consistent assessment of global green, blue and virtual water fluxes in the context of food production: Regional stresses and worldwide teleconnections”, funded by the German Research Foundation (DFG). This project is endorsed as a partner project of the GWSP.
