Although water is a universal human requirement, the use people make of it varies hugely. The average Malian draws 4 cubic metres a year for domestic use, the average American 215. Include all uses, and the figures range from 20 cubic metres for the average Ugandan to over 5,000 for his Turkmenistani counterpart. The statistics can be misleading: in places where rain falls copiously and evenly from the skies, withdrawals will be small. Moreover, water-blessed countries have much less reason to be careful with their resources than the water-starved. Yet high use of water is not necessarily bad. It depends how it is employed, and whether it is naturally replaced. However essential, farming is not the most lucrative use of water. Industry generates about 70 times as much value from a litre of water as agriculture, which helps to explain why industry takes the lion's share in most rich countries. Yet the ratio of water use to GDP has declined dramatically in many rich and middle-income countries in recent decades, which suggests that industry can use water much more productively if it tries.
