2009 California climate adaptation strategy

The 2009 California climate adaptation strategy was a statewide plan issued by the California Natural Resources Agency with contributions from the California Environmental Protection Agency, the California Energy Commission, and the Governor of California's office. It synthesized findings from the Intergovernmental Panel on Climate Change synthesis reports, drew on regional planning models used by the Metropolitan Transportation Commission, and aligned with Assembly Bill 32 and Senate Bill 375 to guide resilience for coastal, agricultural, urban, and natural systems. The strategy integrated scientific assessment from institutions such as the Scripps Institution of Oceanography, the Lawrence Berkeley National Laboratory, and the Stanford Woods Institute for the Environment to recommend prioritized actions.

Background and development

Development of the strategy followed precedent climate work by United States Global Change Research Program contributors and state-level initiatives including reports by the California Climate Change Center at the Lawrence Berkeley National Laboratory. Key participants included the California Environmental Protection Agency, the California Air Resources Board, and the California Department of Water Resources, with technical input from the U.S. Geological Survey and National Oceanic and Atmospheric Administration. The drafting process engaged regional stakeholders such as the San Francisco Bay Conservation and Development Commission, the Los Angeles County Department of Public Works, and academic partners like University of California, Berkeley and University of California, Davis. Policy framing referenced international protocols such as the Kyoto Protocol and national strategies prepared by the White House Council on Environmental Quality.

Key objectives and guiding principles

The document articulated objectives to protect public health, preserve California's infrastructure, and sustain economic sectors including California agriculture and tourism in California. Principles emphasized adaptive management, stakeholder engagement, and integration with existing mandates like Assembly Bill 32 and planning frameworks used by the Association of Bay Area Governments and the Southern California Association of Governments. The strategy recommended aligning local hazard mitigation plans used by the Federal Emergency Management Agency with regional planning bodies such as the Sacramento Area Council of Governments and the San Diego Association of Governments.

Vulnerability assessment and risk priorities

Vulnerability assessment drew on climate projections from the Intergovernmental Panel on Climate Change and regional downscaling by the California Climate Change Center and Scripps Institution of Oceanography. Identified risks included sea level rise affecting the San Francisco Bay, increased wildfire risk in ranges like the Sierra Nevada, altered hydrology for the Central Valley, and heatwave impacts in urban areas such as Los Angeles and San Diego. The strategy prioritized risks to transportation corridors like Interstate 5, water infrastructure managed by the California Department of Water Resources and agencies such as the Metropolitan Water District of Southern California, and ecosystems including the Sacramento–San Joaquin River Delta and Channel Islands National Marine Sanctuary.

Sectoral adaptation measures

Recommended measures spanned coastal protection for places including Santa Cruz and Monterey, forest management in the Sierra Nevada and Mendocino National Forest, and water portfolio strategies involving the Central Valley Project and the State Water Project. Urban measures referenced green infrastructure examples from San Francisco and Portland, Oregon and public health preparedness models used by the California Department of Public Health. Agricultural adaptation invoked techniques promoted by University of California, Davis Extension and irrigation practices linked to the Natural Resources Conservation Service. Transportation resilience involved asset mapping used by the California Department of Transportation and floodplain management practices aligned with the Federal Emergency Management Agency.

Implementation, funding, and coordination

Implementation called for coordination among state entities including the California Natural Resources Agency, the California Environmental Protection Agency, the California Air Resources Board, and local governments represented by councils of governments such as the San Joaquin Council of Governments. Funding pathways referenced state budgeting processes overseen by the California State Legislature and grant programs administered by federal partners like the Department of the Interior and U.S. Department of Agriculture. The strategy suggested leveraging finance mechanisms from the California Infrastructure and Economic Development Bank and collaboration with philanthropic partners such as the William and Flora Hewlett Foundation and the Packard Foundation.

Monitoring, evaluation, and updates

The plan proposed monitoring frameworks drawing on scientific networks including the National Oceanic and Atmospheric Administration, the U.S. Geological Survey, and academic partners such as Stanford University and the University of California, Santa Barbara. Evaluation metrics were to be coordinated with the California Environmental Protection Agency's reporting systems and tied to statutory review cycles under Assembly Bill 32. The strategy anticipated iterative updates informed by subsequent climate assessments from the Intergovernmental Panel on Climate Change and state reports produced by the California Climate Change Center.

Reception, critiques, and subsequent influence

Initial reception included endorsements from environmental organizations like the Natural Resources Defense Council and criticism from some water and agricultural stakeholders represented by organizations such as the Western Growers Association and California Farm Bureau Federation over water allocation and land-use implications. Academic critiques from researchers at University of California, Berkeley and Scripps Institution of Oceanography focused on the need for finer-resolution modeling and stronger enforcement mechanisms, while municipal planners in jurisdictions including San Diego and Los Angeles cited implementation challenges. The 2009 strategy influenced later statewide actions including the climate adaptation components of Senate Bill 7X and informed regional plans under Senate Bill 375, and it contributed to evolving practice in agencies such as the California Natural Resources Agency and the California Coastal Commission.
