Discover how much water the sector uses and how groundwater laws and climate change are bringing change.
Report Preparing California for a Changing Climate By Ellen Hanak, Louise Bedsworth Nov 17, 2008 California has ambitious plans to cut greenhouse gas emissions. But the state also needs an integrated policy to prepare for―and adapt to―climate change. This report finds that some institutions, such as water agencies and electrical utilities, have already begun planning for change. But other areas have yet to prepare effectively for the challenges of a changing California. More information can be found in the following supporting reports: Climate Change in California: Scenarios for Adaptation Adapting California’s Water Management to Climate Change Adaptation of California’s Electricity Sector to Climate Change California Coastal Management with a Changing Climate Air Quality Planning and California’s Changing Climate Climate Change and California’s Public Health Institutions Conservation and Management of Ecological Systems in a Changing California
California Economic Policy, Report Lawns and Water Demand in California By Ellen Hanak, Matthew Davis Jul 12, 2006 Over the next 25 years, outdoor water use will be a major factor in escalating water demand in California. The demand will be aggravated by the dominant land-use pattern in inland areas: single-family homes with lush lawns. Without efforts aimed specifically at reducing outdoor urban water use, the demand will pose significant financial and environmental challenges for California. In this issue of CEP, the authors analyze population growth and housing trends in the state’s major climactic regions, estimate residential lot and yard sizes, and examine the water needs of cool-season turf grass lawns. They also evaluate several outdoor water conservation programs.
Report Water for Growth: California’s New Frontier By Ellen Hanak Jul 27, 2005 California’s population is expected to add another 14 million people by 2030, reaching a total of 48 million. One of the most serious concerns of policymakers is whether the state will be able to supply the water needed to sustain such a population. Although many large water projects in the past were undertaken with state and federal leadership, most current options are local or regional in scope. The frontline agencies responsible for water supply are the hundreds of municipal utilities serving the state’s residential and commercial customers. In this report, the author examines how well California is faring in meeting the water supply challenges of growth throughout the state and the extent to which local governments are integrating water supply concerns into their land-use planning. The report also evaluates progress in implementing the new “show me the water” laws, SB 610 and SB 221, which require up-front screening of water availability for large development projects.
Statewide Survey PPIC Statewide Survey: Californians and the Environment By Mark Baldassare, Jennifer Paluch, Dean Bonner, Sonja Petek Jul 29, 2009 Some findings of the current survey: Solid majorities of Californians favor government regulation of greenhouse gas emissions and policies to curb global warming. More Californians support than oppose expanding coastal oil drilling; even more favor improving fuel efficiency. Three in four Californians say the state should expand public transit and use existing transportation networks more efficiently—only 18 percent say the state should build more freeways.

Report Transitions for the Delta Economy By Ellen Hanak, Jay Lund, Richard Howitt, Josué Medellín-Azuara Jan 10, 2012 Enormous changes—from natural forces to management decisions—are coming to California’s fragile Delta region and will have broad effects on its residents. This report finds that in the first half of this century, the Delta as a whole is likely to experience a loss of 1 percent of economic activity as a result of these changes. It also identifies planning priorities for managing the Delta’s future. This research was supported with funding from the Watershed Sciences Center at UC Davis.
Report A Path Forward for California’s Freshwater Ecosystems By Jeffrey Mount, Brian Gray, Karrigan Bork, James Cloern ... Dec 4, 2019 California’s freshwater ecosystems are under pressure and its aquatic biodiversity is in decline. The state needs a new approach to protect the many beneficial uses these ecosystems provide. This report describes a way to manage the state’s freshwater ecosystems—called “ecosystem-based management”—that can improve conditions for native biodiversity and human uses, and increase resilience to climate change.
Report Integrated Management of Delta Stressors: Institutional and Legal Options By Ellen Hanak, Jay Lund, Jeffrey Mount, Brian Gray Apr 28, 2013 Despite some recent progress, the current institutional landscape for regulation and management of stressors in the in the Sacramento–San Joaquin Delta is highly fragmented. A modest but powerful set of institutional changes can help produce better environmental outcomes while containing management costs—which are likely to exceed several hundred million dollars annually. This report lays out proposals for institutional reform. 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. Scientist and Stakeholder Views on the Delta Ecosystem (Hanak et al. 2013) presents detailed results of the two surveys conducted by the report’s authors. 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.
Report Improving the Health of California’s Headwater Forests By Van Butsic, Henry McCann, Jodi Axelson, Brian Gray ... Sep 18, 2017 This report looks at regulatory, legal, and management reforms that can help build resilience in the state’s headwater forests and prepare them for a challenging future.
Report Water and the California Economy By Ellen Hanak, Jay Lund, Richard Howitt, Brian Gray ... May 30, 2012 California’s economy can grow and prosper despite droughts and water shortages caused by a changing climate—but only if threats to the water system are addressed now. So far, innovative water management has supported the needs of a growing population but serious concerns remain, including water supply reliability and declining groundwater basins. This research was supported with funding from the S.D. Bechtel, Jr. Foundation.
