The Economic Impacts of Central Valley Salinity
University of California Davis       

Final Report to the State Water Resources Control Board Contract 05-417-150-0
March 20, 2009 Richard Howitt      

The study results showed that if salinity increases at the current rate until 2030, the direct annual costs will range from $1 billion to $1.5 billion. Total annual income impacts to California will range between $1.7 billion to $3 billion by 2030. The income impacts to the Central Valley will range between $1.2 billion and $2.2 billion. The production of goods and services in California could be reduced from $5 billion to $8.7 billion a year. The Central Valley output reduction would range between $2.8 billion to $5.3 billion. Furthermore, there is $145 million per year of non-market costs. In terms of job losses the increase in salinity by 2030 could cost the Central Valley economy 27,000 to 53,000 jobs. California could lose 34,000 to 64,000 jobs. In short, the problem is substantial and growing steadily. The magnitude of the economic and employment losses justifies a more detailed study of remedial action and correction policies.

From this study the CV-SALTS program will be piloting the sources of salt and nitrate.  This methodology will be used to review the salt inventory for the entire region.  Additionally the committees are scoping and will be developing a beneficial use and objectives study to develop data critical to the review of the benefical uses of water for the valley and the salt and nitrate objectives needed to protect them.
