Water Stress and a Changing San Joaquin Valley

By Ellen Hanak, Jay Lund, Richard Howitt, Peter Moyle ...

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.

A Pragmatic Reason to Protect Freshwater Fish

By Ellen Hanak, Jeffrey Mount, Peter Moyle

When species make the endangered species list, we’ve not only failed them, we’ve made it harder to manage water during drought.

What If California’s Drought Continues?

By Ellen Hanak, Jay Lund, Jeffrey Mount, Peter Moyle ...

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.

Why Farming Needs the New Groundwater Law

By Ellen Hanak, Sarge Green, David Zoldoske

Declines in groundwater levels are causing problems around the state. The new groundwater law will help manage groundwater so that it’s available during droughts, when it’s most needed.

Policy Priorities for Managing Drought

By Ellen Hanak, Jay Lund, Jeffrey Mount, Peter Moyle ...

State, federal, and local water managers have worked diligently to reduce the economic, social, and environmental harm from the current drought. But as the drought continues, the challenges will grow more acute. California can learn from experiences to date—and from Australia’s response to its Millennium Drought—to better prepare both for the year ahead and for future droughts. State leaders should address weaknesses in four areas of drought preparation and response, by: 1) improving water use information, 2) setting clear goals and priorities for public health and the environment, 3) promoting water conservation and more resilient water supplies, and 4) strengthening environmental management.
