The $20 million, 34,000-square-foot teaching-and-research complex is the first winery, brewery or food-processing facility expected to earn LEED Platinum certification, the highest environmental rating awarded by the U.S. Green Building Council. It is intended to become self-sustainable in energy and water use.
Neal Van Alfen, dean of the College of Agricultural and Environmental Sciences at UC Davis, said, "It will serve as a model for industries throughout the nation that are also committed both to environmental excellence and production efficiency."
The complex houses a brewery, general foods-processing plant, milk-processing laboratory, and a teaching-and-research winery which will serve as a test bed for production processes that conserve water, energy, and other resources. The complex is adjacent to a 12-acre teaching-and-research vineyard.
Its environmentally friendly features include on-site solar power generation, a large-capacity system for capturing rainwater and conserving processing water, and many other features. The facility is expected to be carbon zero in carbon emissions.
Growing concern about social issues related to agriculture – working conditions for laborers and environmental impacts, for example – is giving rise to consumer and retailer interest in buying products that were farmed using “sustainable” methods.
“Sustainable agriculture” is not easy to define. In general, the system puts an emphasis on practices that have long-term environmental and social benefits – such as reducing pollution and providing stable jobs. Sustainable products are perhaps not as familiar as “organic,” but examples of retailers capitalizing on the concept are numerous.
- Walmart is training 1 million farmers and workers worldwide on crop selection and sustainable-farming practices
- Sysco asserts online that it offers products that come from suppliers that take care of the land
- Del Monte Foods formalized its environmental goals in three key areas - waste, greenhouse gas emissions and water
Understanding farmers’ perceptions about adopting sustainable farming is a goal of research by Mark Lubell, professor of environmental science and policy at UC Davis. To document whether winegrape farmers and other experts believe the environmental and economic benefits of adopting sustainable practices are worth the cost, Lubell analyzed data from three sources: a survey of viticulture outreach professionals, including UC farm advisors, campus-based researchers and vineyard management consultants; a 2008 survey of winegrape growers who are part of the California Sustainable Winegrowing Alliance’s Sustainable Winegrowing Program; and 16 interviews with winegrape growers in the Lodi, Napa Valley and Central Coast winegrowing regions.
Many “sustainable” practices were perceived to have economic benefits and are likely to be adopted by growers, Lubbell found. Of the practices where economic benefits outweigh the costs, the practices with the highest environmental benefits are perceived to be:
- Spot spraying for pest problems instead of treating entire vineyards
- Pheromones to disrupt pest mating
- Computer models for disease forecasting
- Dust reduction with cover crops
- Monitoring evapo-transpiration to determine when to irrigate
“Important challenges to the adoption of sustainable practices arise when economic benefits are low and when growers have uncertainty about benefits,” Lubell said.
The take-home message for advisors and crop consultants: Outreach programs should focus grower education on activities with both economic and environmental benefits. Reducing uncertainty should be a primary goal of all outreach programs and requires research to demonstrate the effectiveness of agricultural practices.
Lubell believes adopting sustainable methods makes sense for winegrape growers.
“The market for sustainability is not mature enough now to get a price differentiation,” he said. “But a ‘green’ market is emerging. Some people are willing to pay for it and more will pay over time.”

Long before European settlers arrived in America, the Los Angeles River was an important source of food and water for native peoples. Europeans settled the Los Angeles area in part because of the river and the fertile alluvial soils it provided. The river and its tributaries frequently flooded and changed course, forming wide alluvial floodplains that extended across southern Los Angeles from modern day Santa Monica to Long Beach. When Los Angeles began its transition to teeming metropolis and settled these flat floodplains, the river's natural characteristics led to disastrous flooding.
In the interest of saving lives and property, civil engineers sloped the banks and encased them in more than 30 miles of concrete, a move that completely altered the fishery. Recently completed UC Cooperative Extension research indicates that, despite the concrete and influx of pollutants from LA storm drains and sewage treatment plants, the Los Angeles River is still capable of sustaining life.
Working with Friends of the Los Angeles River, an organization interested in restoring the LA River to a more natural state, UCCE natural resources advisor Sabrina Drill surveyed the fish population in the river's eight-mile Glendale Narrows area, a section that, because of its underlying geology, was left with a natural bottom. The researchers discovered a diverse and bountiful fish population in this stretch of the river.
"To our surprise and delight, toxicity reports show the small number of fish we tested to be free of mercury and have extremely low levels of PCBs," Drill said. "This may not be true for the rest of the river. Glendale Narrows is one of the cleanest sections, probably because the natural river bottom cleans itself and because of the high quality effluent coming out of upstream water reclamation plants."
The survey identified eight species of fishes, none of them native, plus tadpoles and red swamp crayfish in the river. The eight fish species are: fathead minnow, carp, black bullhead, Amazon sailfin catfish, mosquito fish, green sunfish, largemouth bass and tilapia. They hail from Africa, South America, Eastern North America and Asia.
Whether reestablishment of native species to the river is possible remains to be seen, and may not be the most important factor in river restoration.
"Difficult though it may be, you can't make the LA River what it used to be simply by digging up the concrete," Drill said. "Because of all the development, the water we import, and changes in hydrology, temperature, and water quality, it’s not the same system it was before people settled here."
But restoration can still take place, and Drill believes that in the next 10 to 20 years, large-scale habitat restoration and restoration of some historical floodplains will dramatically enhance the ecological function and natural beauty of the Los Angeles River.

Four baby Pacific fishers were released in the forest this week, with the aid of UC Berkeley scientists who are studying the Sierra Nevada population of the rare weasel-like carnivore.
Pacific fishers were once an abundant species, but the population has been in decline for more than 20 years. As part of the Sierra Nevada Adaptive Management Project (SNAMP), an ongoing study aims to determine what factors are influencing the fishers' fate, such as habitat loss, timber harvest, disease, development and climate change.
"We are extremely excited that the four fisher kits have been repatriated back out in the forest, where we hope they will survive and become part of the fisher population in this area," said Rick Sweitzer, UC Berkeley Research Wildlife Biologist and Adjunct Associate Professor.
Last May, two fishers being monitored as part of the SNAMP study were killed – one by a bobcat, the other hit by a car on Highway 41. It just so happened they were both nursing mothers.
“We knew that the female fishers had kits, and that these animals are rare in California,” Sweitzer said. “We couldn’t in good conscience let the baby animals perish in their den cavities knowing we might be able to intervene.”
The scientists staged two daring rescues and spirited the babies to the Fresno Chaffee Zoo for care. In time, the young animals were moved to a large pen and taught to hunt live prey by a regional wildlife rehabilitation organization. The young fisher kits have been under the care of the Fresno Chaffee Zoo, by agreement with the California Department of Fish and Game. Last week, the Department of Fish and Game gave approval for the "juvenile" fishers to be released back out into the forest.
"We aided this process by finding the most appropriate release areas where the animals will be most likely to find food in good quality fisher habitat," said Sweitzer.
Two of the fisher kits were released in the west Kaiser area. Two others were returned to the Beasore Road/Chilkoot Lake area of the Sierra National Forest, close to where their mother was killed in the SNAMP study area.
Unusual circumstances precipitated the two fishers' release into an area where their population is being researched. Late last year, two fishers died during captures when they were given anesthetic agents from a particular production lot that, unbeknownst to the scientists, had been causing serious problems with domestic pets and other animals and were subsequently recalled, but not until after both fisher deaths had occurred. With permission from the California Department of Fish and Game, two of the fisher kits replaced the two that died because of the research project.
