A Message from Dean Helene Dillard: CA&ES researchers help find solutions to California’s water woes

DeanAfter December rains brought relief—and some measure of hope—to our parched state, a record dry January and subpar February makes a fourth year of drought almost a certainty for California. The below average water levels in our reservoirs and overtaxed groundwater aquifers have placed a heavy burden on the state. Agriculture, in particular, is struggling to make the best of a bad situation.

The College of Agricultural and Environmental Sciences plays a vital role in helping the state develop science-based solutions to stretch scarce water resources. Our researchers are working with growers, industry, and agencies throughout California to find practical solutions. Here are a few examples.

Department of Land, Air and Water Resources professor Helen Dahlke and her team are making headway with groundwater banking, where excess surface water from storms and flood releases can help replenish aquifers. Dahlke’s team has been conducting tests in an alfalfa field near Scott River in Siskiyou County, applying water in various amounts to analyze soil saturation, infiltration rates, and whether winter irrigation adversely affects alfalfa production. The team hopes to launch similar projects in other areas.

In Monterey County’s Pajaro Valley, Professor Samuel Sandoval Solis, a Cooperative Extension specialist with the Department of Land, Air and Water Resources, is leading a water-saving project. Sandoval’s team identified steps that conserved 5,100 acre feet per year—41 percent of what was needed to avoid overdraft—without sacrificing crop quality and yield. Sandoval’s recommendations focused on optimizing irrigation—that fine line between applying too much and too little water.

In yet another example, plant physiology professor Ken Shackel is involved in a five-year experiment in Merced, Kern, and Tehama counties to see how different irrigation levels affect almond yields. Shackel’s team is applying between 70 and 115 percent of recommended irrigation levels based on weather-station data. Preliminary results indicate yield may start dropping at about 90 percent. That kind of information takes the guesswork out of how to get the most of limited water supplies. Similarly, Department of Viticulture and Enology professor David Block and his team are designing a grapevine irrigation system that applies water based on each vine’s individual needs.

Plant breeders are developing new varieties of food and fiber that can thrive in dry, saline conditions. Department of Plant Sciences professor Eduardo Blumwald is working to develop rice varieties that don’t shut down in drought conditions, but rather continue to produce the nutrients necessary to make rice grains. Plant sciences professors Jorge Dubcovsky and Jan Dvorak are mapping, isolating, and cloning genes from the massive wheat genome. Viticulture and enology professor Andy Walker is breeding drought- and salt-tolerant grape rootstocks by optimizing root architecture to improve water-use efficiency.

Many other examples of innovative projects with significant impact can be found throughout the college. Food science professor Chris Simmons is working with food processers, inspecting and analyzing pipes and plant procedures to find inexpensive ways to save water and energy. Dave Fujino, executive director of the California Center for Urban Horticulture, is helping extend information on efficient irrigation management and drought-tolerant plants to reduce urban water use and prevent runoff from landscapes.

While the drought’s impact on agriculture drives important research, we must not overlook the work of our scientists studying how drought affects the environment. Peter Moyle, a professor of wildlife, fish and conservation biology, has been monitoring native fish populations through droughts for more than three decades and has documented the declining status of many of these species. He and fellow scientists determined that climate change and human-caused degradation to aquatic habitats pose serious threats to more than 80 percent of our native fish.

Rangeland watershed specialist Ken Tate in the Department of Plant Sciences works with the ranching community to ensure the health of California’s rangeland. California has millions of acres of public and private rangeland that is vitally important as a source of livestock forage, wildlife habitat, plant diversity, and clean water. Tate and his team organized a recent symposium on campus for an audience of more than 200 ranchers, scientists, land managers, water regulators, and others to learn about many facets of water and other issues on rangelands as they relate to livestock grazing.

There is no one, simple way to deal with California’s drought. But CA&ES researchers are hard at work developing the solutions for managing our vital, scarce water resources.
