06 helenedillardA Message from Dean Helene Dillard: CA&ES Faculty Vital to California Water Challenges

The top concern for agricultural stakeholders, environmentalists, and many other Californians right now is water. As experts weigh in on the drought, many faculty members from our college are providing science-based information to help the state address water resource challenges.

At a University of California “Drought Science, Policy and Management Summit” held in Sacramento in April, our college faculty contributed to discussions on the economic effects of drought, its impact on agriculture and endangered species, as well as water management and water policy in the state.

Cooperative Extension specialists based in our college are contributing to an online seminar series sponsored by UC ANR and the California Department of Water Resources. Our experts provide insight on groundwater, water management strategies for specific crops, detecting water stress in crops, and other topics as well.

Every day, our college faculty, staff, and students conduct research that will help Californians mitigate the effects of the current drought and help prepare the state for future water shortages due to climate change and variations in the availability of water.

At the multidisciplinary UC Davis Center for Watershed Sciences, scientists from our college collaborate with experts from engineering, geology, and other departments on water policy issues. Faculty from the Department of Agricultural and Resource Economics analyze the economic impact of the drought on California agriculture. Others assess the Sacramento–San Joaquin Delta—the major supply of freshwater for the state—for ways to ensure a stable water supply for agriculture and urban areas while maintaining a balanced and healthy environment.

Another area of exploration is more efficient use of water in the processing of food and beverages. At the Robert Mondavi Institute for Wine and Food Science, our food processing pilot plant allows food scientists to test ways to process fruits and vegetables using less water. Our Teaching and Research Winery and the adjoining Jess S. Jackson Sustainable Winery Building have made our facility the most water-efficient winery ever built, modeling water-saving techniques for the California wine industry.

In plant sciences, we have experts who help agricultural stakeholders manage water in ways that benefit agriculture and rangeland, as well as wildlife and ecosystems. Rice farmers are providing wetland habitat for fish and waterfowl. Ranchers are adopting techniques developed by UC Davis scientists to help protect water quality on rangeland and promote herd sustainability. In addition, we have plant scientists who are breeding drought-resistant crop varieties and are exploring the fundamental science behind drought and salinity resistance in plants.

Our irrigation specialists in the Department of Biological and Agricultural Engineering and the Department of Land, Air and Water Resources conduct research that helps make optimal use of water for agriculture, which utilizes approximately 80 percent of the developed (managed) water supply in the state. Our groundwater experts examine the impact of agricultural practices on groundwater and the effects of pumping groundwater to make up for shortages of surface water deliveries. The goal is not only to identify the problems, but also to develop solutions for these critical issues.

We also have wildlife biologists and hydrologists who contribute research on the restoration of rivers and the management of water flow for endangered fish and wildlife, as well as the health of the overall ecosystem. Experts in the Department of Land, Air and Water Resources are tracking hydrology shifts in the state that are due to climate variability and changes in water availability.

In the Department of Environmental Science and Policy, experts analyze the risks of wildfire vulnerability, particularly with the higher temperatures associated with climate change. To conserve the state’s biodiversity, our scientists are helping resource managers develop adaptation strategies to reduce the risks of climate-driven extinction of species.

Our California Center for Urban Horticulture provides homeowners and others with information on drought-resistant landscaping and efficient irrigation. This program is conducting a series of workshops throughout the state this summer to show landscape professionals how to save water by making improvements to irrigations systems.

A safe and reliable water supply is vital to agriculture, the environment, and the people of California. Our faculty, staff, and students are vital to California, helping to promote water conservation, preserve water quality, protect watersheds, improve water management and policies, restore ecosystems, and address changes in water availability due to climate change.

flintMary Louise Flint: James H. Meyer Distinguished Achievement Award

Mary Louise Flint, a UC Davis Cooperative Extension specialist and associate director of the UC Statewide IPM Program, is the 2014 recipient of the James H. Meyer Distinguished Achievement Award. The award recognizes a distinguished career of achievement by an Academic Federation member. A secondary but important consideration is voluntary service to the campus, UC community, or state, regional, or national bodies.

Flint oversaw development of UC IPM’s highly regarded series of manuals on 15 different agricultural crops; online pest management guidelines; and pest notes for home, garden, landscape, and urban audiences. She is the author of several important books on integrated pest management, including “Pests of the Garden and Small Farm,” “IPM in Practice: Principles and Methods of IPM,” and “The Natural Enemies Handbook.”  Flint also developed hands-on train-the-trainer programs for UC Master Gardeners, retail nursery personnel, and landscape professionals.

Meyer, a former CA&ES dean and UC Davis chancellor, was Flint’s father-in-law. “This is a special award for me because of my father-in-law and his strong support for the Academic Federation and the Cooperative Extension specialists, Agricultural Experiment Station researchers, and other non-Senate academics it represents,” she said.

Gurdev KhushGurdev Khush: Honorary Doctorate from McGill University

Gurdev Khush, an adjunct professor in the Department of Plant Sciences, received an honorary doctorate degree from McGill University. He is an agronomist who spearheaded a program developing improved rice varieties that were part of the Green Revolution.

In 1967, Khush joined the International Rice Research Institute (IRRI) in the Philippines and was appointed head of the plant breeding division a few years later. He conceptualized and developed a new type of rice with a 20 percent higher yield potential. The adoption of modern varieties has helped double the world’s rice supply and enabled self-sufficiency in most of the major rice-producing countries in the world.

For his contribution to world food security, Khush received the World Food Prize (1996) and the Wolf Prize in Agriculture (2000). Ronald P. Cantrell, former director general of the IRRI, said of Khush: “While his name may have passed the lips of many, his life’s work passed the lips of almost half mankind.”
