Drought and economic depression are driving thousands from Oklahoma. As their land becomes just another strip in the dust bowl, the Joads, a family of sharecroppers, decide they have no choice but to follow.

Water scarcity is the next big climate crisis. Water stress – not just scarcity, but also quality issues caused by pollution – is already driving the first waves of climate refugees. Rivers are drying out before they meet the oceans and ancient lakes are disappearing. It’s increasingly clear that human mismanagement of water is dangerously unsustainable, for both ecological and human survival. And yet in recent years some key countries have been quietly and very successfully addressing water stress. How are Singapore and Israel, for example – both severely water-stressed countries – not in the same predicament as Chennai or California? In The Last Drop, award-winning environmental journalist Tim Smedley meets experts, victims, activists and pioneers to find out how we can mend the water table that our survival depends upon. He offers a fascinating, universally relevant account of the environmental and human factors that have led us to this point, and suggests practical ways to address the crisis, before it’s too late.
