The world has a water shortage, not a food shortage

MOST people may drink only two litres of water a day, but they consume about 3,000 if the water that goes into their food is taken into account. The rich gulp down far more, since they tend to eat more meat, which takes far more water to produce than grains. So as the world’s population grows and incomes rise, farmers will—if they use today’s methods—need a great deal more water to keep everyone fed: 2,000 more cubic kilometres a year by 2030, according to the International Water Management Institute (IWMI), a research centre, or over a quarter more than they use today. Yet in many farming regions, water is scarce and likely to get scarcer as global warming worsens. The world is facing not so much a food crisis as a water crisis, argues Colin Chartres, IWMI’s director-general.

The solution, Mr Chartres and others contend, is more efficient use of water or, as the sloganeers put it, “more crop per drop”. Some 1.2 bill…

But Pickens is just one of thousands of capitalists who sell precious Ogallala water for private gain. Like him, they are aided by government.

Pickens shouldn't be allowed to sell 65 billion gallons a year as he proposes, but neither should Plains farmers be allowed to pump 6.2 trillion gallons annually, over half of which is poured onto corn. With populations increasing and global warming likely to cause widespread drought, we should redirect the billions we spend on co…
