Some half a million acres of the most productive agricultural region on the planet — California’s San Joaquin Valley — will have to fall fallow, a new report says. There just isn’t enough water.
Farmers have been using so much water that wells have run dry and the ground has sunk as much as 28 feet in places. So California passed a law back in 2014 to stop its overdraft of groundwater and gave itself 20 years to figure out how to make it work. According to a report just out from the nonpartisan Public Policy Institute of California, it will require giving up a chunk of farmland more than twice the size of San Diego.
