SALINITY IS A LOOMING THREAT TO AGRICULTURE AND groundwater sustainability in many parts of the world and in California. According to Central Valley Salinity Alternatives for Long-term Sustainability (CV-SALTS), nearly 2 million tons of salt accumulate each year in the San Joaquin Valley, where more than 250,000 acres of irrigated land have been fallowed and 1.5 million acres are potentially salt impaired. In a March 2009 study, The Economic Impacts of Central Valley Salinity, the University of California, Davis reported that if salinity keeps increasing at the current rate, California’s Central Valley will experience reductions in income ranging from $1.2 billion to $2.2 billion a year by 2030.
