Scientist and Stakeholder Views on the Delta Ecosystem

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

There is broad scientific recognition that a wide range of ecosystem stressors are responsible for the declines in native fish populations in the Sacramento–San Joaquin Delta. But science and policymaking have been at odds about the roles of different stressors and the potential of various management actions to improve ecosystem health. In the summer of 2012, PPIC conducted two confidential surveys on the impact of ecosystem stressors: one sought input from scientific experts and the other focused on stakeholders and policymakers. This report analyzes the results and examines the implications of both surveys.

This research was supported with funding from the S. D. Bechtel, Jr. Foundation.

Several companion reports contain related findings:

Aquatic Ecosystem Stressors in the Sacramento–San Joaquin Delta (Mount et al. 2012) summarizes the science of Delta ecosystem stressors for a policymaking audience.

Costs of Ecosystem Management Actions for the Sacramento–San Joaquin Delta (Medellín-Azuara et al. 2013) assesses costs of water management actions.

Integrated Management of Delta Stressors: Institutional and Legal Options (Gray et al. 2013) lays out proposals for institutional reform of science, management, and regulation.

Stress Relief: Prescriptions for a Healthier Delta Ecosystem (Hanak et al. 2013) summarizes the overall research project and the recommendations it generated.

Where the Wild Things Aren’t: Making the Delta a Better Place for Native Species (Moyle et al. 2012) outlines a realistic long-term vision for achieving a healthier ecosystem.

Driving Change: Reducing Vehicle Miles Traveled in California

By Ellen Hanak, Louise Bedsworth, Jed Kolko

Can Californians cut down on their driving? Encouraging job growth near transit stations will help. So will pursuing policies that raise the cost of driving. This report examines California’s progress in these and other areas, finding both opportunities and challenges ahead.

This research was supported with funding from The William and Flora Hewlett Foundation, as part of the California 2025 project on the state's future, and the David A. Coulter Family Foundation.

Policy Brief: Improving California’s Water Market

By Andrew Ayres, Ellen Hanak, Brian Gray, Gokce Sencan ...

This policy brief distills key takeaways from our report on water trading and banking in California, and how they will help the state bring its groundwater basins into balance under the Sustainable Groundwater Management Act (SGMA). A broad range of policy changes could improve and expand California’s water market while protecting communities from harm.
