Forget about peak oil—we should be worrying about peak water: Groundwater basins that supply 2 billion people are being rapidly depleted , according to a new study. Worse: No one knows how long those reserves will last. A research team led by scientists at the University of California, Irvine, examined the world’s 37 largest aquifers between 2003 and 2013 and found that one-third of them were “stressed,” meaning more water was being removed than replenished, according to one of two studies published Tuesday in the journal Water Resources Research . The eight worst-off aquifers, labeled “overstressed,” had virtually no natural replenishment to offset human consumption. The scientists determined the Northwest Sahara Aquifer System, which supplies water to 60 million people, to be the most overstressed. The Indus Basin aquifer of northwestern India and Pakistan is the second-most overstressed, followed by the Murzuk-Djado Basin in northern Africa. California’s Central Valley […]
