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.

Climate Change in California: Scenarios for Adaptation

By Amy Luers, Michael D. Mastrandrea

This report reviews the most recent assessments of the potential impacts of climate change in California, including sea level rise, higher air and water temperatures, reduced Sierra Nevada snowpack and changes in runoff patterns, and an increase in the frequency of extreme events such as droughts and floods. Resource managers, regional planners, and government agencies need to consider climate change in their planning, both to respond to long-term changes in the climate and to the occurrence of extreme events. This report was prepared as part of the Preparing California for a Changing Climate project.

Adapting California’s Water Management to Climate Change

By Ellen Hanak, Jay Lund

Among the potential impacts of climate change, accelerated sea level rise and a reduced Sierra snowpack are the most certain. Both will pose significant challenges for water supply and flood management. Water utilities have already begun to plan for these changes, but flood control agencies are lagging behind and face greater regulatory constraints. State leadership is needed to resolve some threats, including the risk of catastrophic failure in the Sacramento-San Joaquin Delta. This report was prepared as part of the Preparing California for a Changing Climate project.
