The California Institute for Water Resources is a hub for research, extension, and education programs in California that address water resource challenges. As part of the University of California's Division of Agriculture and Natural Resources, our mission is to help bring knowledge into practice.
What We Do

CIWR collaborates with researchers and water agencies to support applied research projects that address water management challenges in California. Through our projects, we focus on systems approaches to identify ways to adapt California's existing water policies and infrastructure for 21st Century needs. We value working across disciplines and institutions through communities of practice, which foster a future generation of water researchers in California.
UC ANR partnered with the California Department of Food and Agriculture (CDFA) to provide technical assistance in applying for and implementing Climate Smart Agriculture Incentives Programs that build resiliency to climate change, increase water use efficiency, and reduce greenhouse gas emissions. The program is hosted by the California Institute for Water Resources. Find a Technical Assistance Provider and learn about our UC ANR-CDFA Climate-Smart Agriculture program.
CIWR has a decade of experience in research and education for nitrogen management. We developed series of science-based nitrogen management publications and related training materials to help growers to develop efficient nitrogen management practices. We also work with experts throughout the UC Cooperative Extension to provide education and training workshops throughout California.
