California Farms Are Sucking Up Enough Groundwater to Put Rhode Island 17 Feet Under

California, the producer of nearly half of the nation’s fruits, veggies, and nuts, plus export crops-four-fifths of the world’s almonds, for example-is entering its third driest year on record. Nearly 80 percent of the state is experiencing “extreme” or “exceptional” drought. In addition to affecting agricultural production the drought will cost the state billions of dollars, thousands of jobs, and a whole lot of groundwater, according to a new report prepared for the California Department of Food and Agriculture by scientists at UC-Davis. The authors used current water data, agricultural models, satellite data, and other methods to predict the economic and environmental toll of the drought through 2016.

Here are four key takeaways:

  • The drought will cost the state $2.2 billion this year: Of these losses, $810 million will come from lower crop revenues, $203 million will come from livestock and dairy losses, and $454 million will come from the cost of pumping additional groundwater. Up to 17,100 seasonal and part-time jobs will be lost.
  • California is experiencing the “greatest absolute reduction in water availability” ever seen: In a normal year, about one-third of California’s irrigation water is drawn from wells that tap into the groundwater supply. The rest is “surface water” from streams, rivers, and reservoirs. This year, the state is losing about one-third of its surface water supply. The hardest hit area is the Central Valley, a normally fertile inland region. Because groundwater isn’t as easily pumped in the Valley as it is on the coasts, and the Colorado River supplies aren’t as accessible as they are in the south, the Valley has lost 410,000 acres to fallowing, an area about 10 times the size of Washington, DC.
