The U.S. Global Change Research Program (USGCRP) advances global change science and informs our national response to the climate crisis—from President Biden’s climate, environmental justice, and nature priorities to decisions at all levels of government and society. Our Changing Planet: The U.S. Global Change Research Program for Fiscal Year 2024 presents highlights of USGCRP’s recent accomplishments, outlines federal investments in global change research, and sets future priorities for federal global change research as USGCRP implements its 2022-2031 Strategic Plan.

Overcoming Organizational Barriers to Implementing Local Government Adaptation Strategies

Local governments across California have taken immense strides to combat climate change. However, many local governments still face organizational barriers to comprehensively implement climate change adaptation measures. Organizational barriers can delay and even prevent local governments from moving from adaptation planning to implementation due to the wide-reaching scope of climate change impacts. This study aims to further the understanding of the diversity of organizational barriers that California local governments experience and to develop a resource to assist local governments in their efforts to overcome these barriers to more effectively implement climate change adaptation strategies.  The research team conducted a broad literature review, an online survey, multiple regional stakeholder workshops, and focus groups to deepen the understanding of organizational barriers to adaptation in California local governments. These research inputs produced findings on organizational barriers experienced by California local government adaptation practitioners, and enabled the development and testing of the Adaptation Capability Advancement Toolkit. The Toolkit aims to help local governments rapidly assess their current capabilities to overcome organizational barriers and identify key actions and resources for increasing their organizational capability for undertaking climate change adaptation. The Toolkit is based on the Capability Maturity Model process improvement framework, and focuses on developing capabilities within four key process areas which were identified as common sources of organizational barriers: leadership and organizational culture, staffing and technical capacity, stakeholder engagement and partnerships, and operations and institutional processes. The Toolkit was tested by California local government adaptation practitioners in order to ground-truth recommendations and assess the utility of suggested actions and resources. Participants indicated that they view the resource as valuable, particularly if continuously supported. 

Overview on Central Valley Project Financing, Cost Allocation, and Repayment Issues

Delta Vision Blue Ribbon Task Force (Delta Vision) | September 18th, 2008

As part of its strategic plan, the Delta Vision Task Force is considering in detail the entire California water infrastructure. This report summarizes and expands upon four individual reports prepared for the Task Force on the financial characteristics and status of the Central Valley Project (CVP). It begins with an overview of CVP history, organization, costs, and repayment. It then focuses on the overall repayment responsibilities of irrigation and municipal and industrial (M&I) contractors as well as those responsibilities specifically for Sacramento Valley and San Joaquin Valley water users. Next is a review of the summary financial statements of the 10 largest San Joaquin Valley contractors based on reports filed with the California State Controller. Following is a discussion of CVP power generation revenues, expenditures, and repayment. The report is then summarized and conclusions presented, with subsequent appendices showing detailed financial statements and repayment responsibilities by individual contractors; and information on power sales over time to various users.

Pathways and Barriers to Corporate Water Stewardship in the Colorado River Basin

Pacific Institute | October 24th, 2023

The Colorado River is the lifeblood of the American West. It supports 30 Native American tribes and farms, cities, and ecosystems in seven US states—Arizona, California

The Colorado River is the lifeblood of the American West. It supports 30 Native American tribes and farms, cities, and ecosystems in seven US states—Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming—and the Mexican states of Baja California and Sonora. However, the river is in crisis. Twenty-three years of drought, the over-allocation of water, and climate change have exacerbated a structural deficit—where more water leaves the system than enters it—for the tribes, communities, and ecosystems that depend on the Colorado River. To advance water resilience in the Colorado River Basin (Basin), accelerated action and investment are required from all sectors. These efforts must be strategic, coordinated, and amplified to effectively tackle the Basin’s challenges. Corporations can play a key role through their operations and supply chains, and by co-funding innovative projects. While a subset of leading companies is engaging in corporate water stewardship (CWS) in the Basin, more is needed to meet the magnitude of the water crisis at hand. This report outlines barriers and pathways to CWS in the Basin based on 20 interviews with corporate and non-corporate stakeholders from February to April 2022, and interviewee feedback on the results. The report is part of a broader Pacific Institute effort to advance CWS in the Basin. We are using these findings to prioritize CWS projects, initiatives, and approaches to pilot and scale in the Basin. More broadly, the findings are applicable to moving CWS toward building long-term water resilience in the Basin and other water-stressed basins around the world.

Patterns and magnitude of flow alteration in California, USA

The importance of the natural flow regime to stream and river health has received growing attention over the last two decades. Quantifying natural river flows has become an essential component of water resource planning, including assessments of water supplies (Vicuna,Maurer, Joyce, Dracup, & Purkey, 2007; Wurbs, 2005), reservoir operations (Hejazi, Cai, & Ruddell, 2008) and drought risk (Meko,Therrell, Baisan, & Hughes, 2001). Understanding the natural flow regime is also crucial for managing stream ecosystems.

Paying for Water in California

Public Policy Institute of California (PPIC) | March 6th, 2014

California faces serious funding gaps in five key areas of water management—including safe drinking water in small, disadvantaged communities; flood protection; management of stormwater and other polluted runoff; aquatic ecosystem management; and integrated water management. These gaps amount to $2 billion to $3 billion a year. But bold efforts by state and local leaders can pave the way to sustainable solutions for California’s critical water resources.

Perspectives and Guidance for Climate Change Analysis

California Department of Water Resources (DWR) | August 14th, 2015

California's water managers face a climate that changes and is changing as a result of both natural and anthropogenic influences. In some settings and for some variables, California’s natural climate variability still dominates anthropogenic influences and will continue to do so for the foreseeable future. In other cases, anthropogenic influences are already evident in important aspects of California's climate. Much research is still required to unravel this tangled web of atmospheric interactions. In any case, California water planning under a changing climate needs to recognize that the causes of variations and changes include both anthropogenic and natural drivers. This technical information record summarizes the scientific and technical guidance and perspectives of the California Department of Water Resources’ (DWR’s) Climate Change Technical Advisory Group (CCTAG) on the use of climate models and associated technical tools for water resource planning. DWR values the work of the members of the CCTAG and will consider this advice as it moves forward in developing specific actions. DWR empaneled this CCTAG in February 2012 to advise DWR on the scientific aspects of climate change, its impacts on water resources, the use of planning approaches and analytical tools, and the development of adaptation responses. DWR requested specific assistance with developing: • A set of future climate scenarios and analysis procedures appropriate for DWR planning. • An approach to extreme climate change scenarios to provide “stress tests.” • Interim guidance on modeling extreme weather events that cause flooding (time permitting within the tenure of the CCTAG).
