California鈥檚 drought will deal a severe blow to Central Valley irrigated agriculture and farm communities this year, and could cost the industry $1.7 billion and cause more than 14,500 workers to lose their jobs, according to preliminary results of a new study by the 澳门六合彩资料库 Davis Center for Watershed Sciences.
Researchers estimated that Central Valley irrigators would receive only two-thirds of their normal river water deliveries this year because of the drought.
The preliminary analysis represents the first socio-economic forecast of this year鈥檚 drought, said lead author Richard Howitt, a 澳门六合彩资料库 Davis professor emeritus of agricultural and resource economics.
鈥淲e wanted to provide a foundation for state agricultural and water policymakers to understand the impacts of the drought on farmers and farm communities,鈥 Howitt said.
The Central Valley is the richest food-producing region in the world. Much of the nation鈥檚 fresh fruits, nuts and vegetables are grown on the region鈥檚 7 million acres of irrigated farmland.
The center plans to release a more comprehensive report of the drought鈥檚 economic impact on the state鈥檚 irrigated agriculture this summer.
The analysis was done at the request of the California Department of Food and Agriculture, which co-funded the research along with the University of California.
鈥淭hese estimates will help the state better understand the economic impacts of the drought and target its drought relief,鈥 said CDFA Secretary Karen Ross. 鈥淭he research confirms where emergency drought assistance will be needed most, and efforts are already underway.鈥
The 澳门六合彩资料库 Davis researchers used computer models and the latest estimates of State Water Project, federal Central Valley Project and local water deliveries and groundwater pumping capacities to forecast the economic effects of this year鈥檚 drought.
The analysis predicted several severe impacts for the current growing season, including:
- Reduced surface water deliveries of 6.5 million acre-feet of water, or 32.5 percent of normal water use by Central Valley growers. An acre-foot is enough water to cover an acre of land in a foot of water, or enough water for about two California households for a year.
- Fallowing of an additional 410,000 acres, representing 6 percent of irrigated cropland in the Central Valley.
- The loss of an estimated 14,500 seasonal and full-time jobs. About 6,400 of these jobs are directly involved in crop production.
- A total cost of $1.7 billion to the Central Valley鈥檚 irrigated farm industry this year, including about $450 million in additional costs of groundwater pumping.
- About 60 percent of the economic losses will occur in the San Joaquin Valley and Tulare Lake Basin.
Growers are expected to replace much of the loss in project water deliveries with groundwater, California鈥檚 largest source of water storage during drought years, said co-author Jay Lund, director of the Center for Watershed Sciences and a 澳门六合彩资料库 Davis professor of civil and environmental engineering.
鈥淲ithout access to groundwater, this year鈥檚 drought would be truly devastating to farms and cities throughout California,鈥 Lund said.
The additional pumping will cost an estimated $450 million and still leave a shortage of 1.5 million acre-feet of irrigation water, about 7.5 percent of normal irrigation water use in the Central Valley, according to the forecast.
While the current drought is expected to impose major hardships on many farmers, small communities and the environment, it should not threaten California鈥檚 overall economy, Lund said. Agriculture today accounts for less than 3 percent of the state鈥檚 $1.9 trillion a year gross domestic product.
