Quick Summary

  • Grant will help researchers develop climate change adaptation strategies for groundwater and irrigated agriculture
  • Researchers will develop tools to help growers meet goals of California's Sustainable Groundwater Management Act
  • Grant will establish Agricultural Water Center of Excellence

Researchers from the University of California, Davis, have been awarded a $10 million by the U.S. Department of Agriculture鈥檚 National Institute of Food and Agriculture to find ways to sustain irrigated agriculture while improving groundwater quantity and quality in the Southwest under a changing climate.

, associate professor of agrohydrology and irrigation at 新澳门六合彩内幕信息 Davis, is leading a team of more than two dozen climate, plant and soil scientists; hydrologists; engineers; economists, educators and extension specialists from 新澳门六合彩内幕信息 Davis and other institutions in California, Arizona and New Mexico. They will develop climate change adaptation management strategies that ensure sustainability of groundwater and irrigated agriculture.

Kisekka says the project team in California will work with Groundwater Sustainability Agencies to develop tools and data to enhance water management at both the farm and groundwater basin scales to improve crop production and achieve sustainability goals under the state鈥檚 , which provides a statewide framework to help protect groundwater resources over the long-term. The research team will also work with grower coalitions to achieve the groundwater quality goals of the Central Valley Salt and Nitrate Management Plan. 

鈥淔or farmers, the biggest challenge threatening their business is water,鈥 Kisekka said. 鈥淥ur project is going to develop climate-smart adaptation management practices to help growers achieve their production goals while addressing the co-benefits for the environment and human health. We are going to develop cutting edge tools to manage groundwater quantity and quality as well as study how policies impact behaviors such as water use in agriculture.鈥

The practices, models and tools developed will be used by growers or their advisors, policymakers, irrigation districts, coalitions and groundwater sustainability agencies to address climate change extremes such as drought or floods.

Growing dependence on groundwater

Growers have increasingly depended on groundwater during multi-year droughts and heat stress. Part of the five-year project includes looking into aquifer systems in California鈥檚 Central Valley, central Arizona and the lower Rio Grande basin in New Mexico. These regions have all experienced unprecedented overdraft, which happens when more water is pumped from a groundwater basin than is replaced from sources, including rainfall.

鈥淔or a long time, a lot of farmers would use groundwater as an insurance policy whenever there was a drought,鈥 Kisekka said. 鈥淭he negative consequences of that became obvious: groundwater levels declined, we had subsidence which causes land to sink, we had deterioration in water quality and so on. What are growers going to do when we have another drought like we are now? We have to think more broadly.鈥 

Kisekka says they will also come up with management practices to improve soil health, develop alternative water supplies and reduce water demand so the region can continue to produce various agriculture commodities, such as vegetables, grapes and almonds.

鈥淲e grow crops in California that we cannot shift to another part of the country because they won鈥檛 grow well there,鈥 Kisekka said. 鈥淲e can鈥檛 grow almonds in the Southeast where they have a lot of water because they require a certain climate. We want to ensure food and nutritional security of the United States by sustaining irrigated agriculture in the Southwest.鈥

Project researchers will also establish innovative education and extension programs to teach students of all backgrounds and ages, as well as the public, about the importance of water in agriculture.

Part of this is to develop educational curriculums from elementary to high school to college, where instructors can pull our modules on water management or sustainable agricultural systems and teach that in their classes,鈥 Kisekka said.

While the depletion of groundwater supplies, among other factors, puts major pressure on agricultural operations in the southwestern region, Kisekka hopes the management practices and tools that will be developed during this project will help improve production and resource sustainability and help make California and the country more resilient to climate change. 新澳门六合彩内幕信息 Davis will establish the Agricultural Water Center of Excellence as part of the grant. This unique Center of Excellence will also have capacity to support agricultural water research, education and extension activities at collaborating institutions with potential impact at local, state, national and international levels.

鈥淲e hope at the end of the day we can still grow food in California and the Southwest in general without drying out our groundwater aquifers,鈥 he said. 鈥淲e have to learn to adapt to climate change. We may not be able to stop it in the short term, but we should be able to adapt.鈥

Researchers from University of California, Berkeley, 新澳门六合彩内幕信息 Agriculture and Natural Resources, Stanford University, CSU Fresno, University of Arizona, New Mexico State University, USDA Agricultural Research Service (Sustainable Agricultural Water Systems Research: Davis, CA and Water Management and Conservation Research: Maricopa, AZ) and USDA Climate Hub are also participating in the project.
