Report Water Stress and a Changing San Joaquin Valley By Ellen Hanak, Jay Lund, Richard Howitt, Peter Moyle ... Mar 1, 2017 The San Joaquin Valley—California’s largest agricultural region and an important contributor to the nation’s food supply—is facing growing water stress and a number of related environmental and public health problems. Large parts of the valley have become dependent on unsustainable pumping of groundwater. Tackling these linked issues with cooperative, coordinated approaches is key to success. This research was supported with funding from the S. D. Bechtel, Jr. Foundation, the TomKat Foundation, and the US Environmental Protection Agency.
