seven times more green water than blue water is used in agriculturalproduction (6,884 billion m 3 compared to 945 billion m 3 ).Agricultural production accounts for 92 per cent of the global waterfootprint, with 78 per cent of world crop production relying onrainfall. Industrial production takes up 4.4 per cent, while 3.6 perthe global water footprint relates to production for export – 19 percent in the agricultural sector and 41 per cent for industry (Hoekstraand Mekonnen, 2012).vulnerable in some areas due to climate change affecting rainfallpatterns. There will also be areas where rainfall will increase,presenting opportunities for new regions. Irrigation has increasedincreased water scarcity downstream. Irrigation is sometimes poorlymonitored and managed, and groundwater may be pumped faster9191Water footprint of production Gm 3 x 1000 / year876543210Agriculturalproduction0.50IndustrialproductionIndustrialproductionDomesticwater supplyDomesticwater supplyWater footprint production categoryWater footprint of production Gm 3 x 1000 / year876543210Cropproduction0.50PasturePasture Water supplyin animal raisingWater supply inanimal raisingAgricultural production categoryFigure 28: Breakdownof the global bluegreen and grey waterfootprint of productionin billion m 3 /year,1996-2005A further breakdownshows that the agriculturesector has the largest waterfootprint, dominated by thegreen water component(Hoekstra andMekonnen, 2012).KeyGreen waterBlue waterGrey waterWWF Living Planet Report 2014 page 48
