Is water the new oil?
It's the world's most precious commodity, yet many of us take it for granted. But that's all about to change... Special report by Juliette Jowit

It's hard to imagine why humans would have chosen the achingly arid stone desert of Wadi Faynan for their first settlement. But water would have been one important reason, says archaeologist Steven Mithen. When Neolithic men and women arrived 11,500 years ago, things were very different: the climate was cooler and wetter; the landscape was covered in vegetation including wild figs, legumes and cereals, and there would have been wild goats and ibex for meat.

Initially WF16, as it's now called, would have been a seasonal camp. But Mithen, professor of early prehistory at the University of Reading, and his fellow archaeologist Bill Finlayson believe that, gradually, people stayed longer. Sifting evidence from so long ago, the archaeologists can't be sure, but remains of food from different seasons and the scale of 'rubbish' piles suggest that about 10,000 years ago the inhabitants stopped moving altogether. If they are right, it would make this one of the oldest sites ever found where humans made a permanent settlement, learned to farm, and changed the course of human civilisation. But the tiny community drawn to water, which attracted successive waves of settlements, would eventually all but destroy the resource which made life possible. It is a pattern that's been repeated for millennia, around the world, and it now threatens us on a global scale.

First people cut trees for shelter and fuel, until rains swept away the soil instead of seeping into shallow aquifers, and the springs dried up. At least as long ago as the Bronze Age, farmers began mankind's obsession with diverting water for crops to feed the growing population. Meanwhile, the moist, cool climate which encouraged the first settlement was naturally becoming drier and hotter.
