New Data Reveals Farmers Are Mining Groundwater at Alarming Rate

“California farms represent 8% of the US’s agriculture value, and the Central Valley is where most of that growing takes place. However, as the state struggles with ongoing droughts, the groundwater supplies are dwindling at a frightening rate. According to satellite technology used by NASA, over a 6.5 year period the groundwater supplies in Central Valley leaked away by an amount equal to 63% of the capacity of Lake Mead, the nation’s largest reservoir. With that much water disappearing, it is harder to replenish supplies when it finally does rain. Does this water debt mean a future food crisis?

National Geographic‘s Sandra Postel reports, “Rarely is groundwater use monitored, measured or regulated. This is true for most of the world, as well as for California’s Central Valley-the fruit and vegetable bowl of the United States. Farmers in the 52,000 square-kilometer valley produce 250 different kinds of crops that together account for 8 percent of the nation’s agricultural value. But thanks to the National Atmospheric and Space Administration’s (NASA) satellite mission called GRACE (the Gravity Recovery and Climate Experiment), we’re getting some excellent assessments of what’s happening to water underground-and the picture is sobering.”
