US farmers fear the return of the Dust Bowl
For years the Ogallala Aquifer, the world’s largest underground body of fresh water, has irrigated thousands of square miles of American farmland. Now it is running dry

The irrigated Plains grow 20 per cent of American grain and corn (maize), and America's 'industrial' agriculture dominates international markets. A collapse of those markets would lead to starvation in Africa and anywhere else where a meal depends on cheap American exports. 'The Ogallala supply is going to run out and the Plains will become uneconomical to farm,' Brauer says. 'That is beyond reasonable argument. Our goal now is to engineer a soft landing. That's all we can do.'
Not A happy story not a happy story at all.
