Report What If California’s Drought Continues? By Ellen Hanak, Jay Lund, Jeffrey Mount, Peter Moyle ... Aug 19, 2015 California is in the fourth year of a severe, hot drought—the kind that is increasingly likely as the climate warms. Although no sector has been untouched, impacts so far have varied greatly, reflecting different levels of drought preparedness. Urban areas are in the best shape, thanks to sustained investments in diversified water portfolios and conservation. Farmers are more vulnerable, but they are also adapting. The greatest vulnerabilities are in some low-income rural communities where wells are running dry and in California’s wetlands, rivers, and forests, where the state’s iconic biodiversity is under extreme threat. Two to three more years of drought will increase challenges in all areas and require continued—and likely increasingly difficult—adaptations. Emergency programs will need to be significantly expanded to get drinking water to rural residents and to prevent major losses of waterbirds and extinctions of numerous native fish species, including most salmon runs. California also needs to start a longer-term effort to build drought resilience in the most vulnerable areas.
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.
Report Comparing Futures for the Sacramento-San Joaquin Delta By Ellen Hanak, Jay Lund, William Fleenor, Jeffrey Mount ... Jul 17, 2008 For over 50 years, California has been pumping water through the Sacramento-San Joaquin Delta for extensive urban and agricultural uses around the state. Today, the Delta is ailing and in urgent need of a new management strategy. This report concludes that building a peripheral canal to carry water around the Delta is the most promising way to balance two critical policy goals: reviving a threatened ecosystem and ensuring a reliable, high-quality water supply for California.
