Agricultural Sustainability Institute Update
I am pleased to welcome Tom Tomich on board as director of our Agricultural Sustainability Institute (ASI), as well as director of the statewide ANR Sustainable Agriculture Research and Education Program (SAREP). These programs will be jointly administered through our college by Tom, who is the first professor to hold the new UC Davis W.K. Kellogg Endowed Chair in Sustainable Food Systems.
An international search was held last year for the director of ASI and SAREP, and Tom Tomich was selected from a pool of highly qualified candidates. Most recently, Tom served as global coordinator of the Alternatives to Slash-and-Burn Programme, hosted by the World Agroforestry Centre and headquartered in Nairobi, Kenya. During his 12 years with the World Agroforestry Centre, Tom worked with collaborative partnerships in the Amazon, Congo Basin, and Southeast Asia to raise the income of rural households without increasing deforestation. Prior to his work with the World Agroforestry Centre, Tom spent 10 years as an associate at the Harvard Institute for International Development and a lecturer at the J.F. Kennedy School of Government and the economics department at Harvard University.
Tom is a native of the Sacramento Valley and did his undergraduate work in economics here on campus. He received his M.S. and Ph.D. degrees from Stanford’s Food Research Institute in agricultural production economics, and food consumption economics and human nutrition.
In his role as the director of the Agricultural Sustainability Institute, Tom will provide leadership for research, teaching, outreach, and extension efforts in agricultural sustainability. He holds a joint faculty appointment in the Department of Human and Community Development and in the Department of Environmental Science and Policy. Please welcome Tom Tomich (530-752-2379; [email protected]), whose office is in Hart Hall.
As always, I value your feedback. If you have questions or comments, please e-mail me.

Transportation expert Daniel Sperling, a civil engineering professor in the Department of Environmental Science and Policy, has been appointed to the Air Resources Board by Gov. Arnold Schwarzenegger. A state regulatory agency, the Air Resources Board consists of 11 members appointed by the governor with consent of the Senate. ARB members include experts from the fields of engineering, law, medicine, and air pollution control. Among the goals of the ARB is to reduce air pollutants in the state based on the best scientific and economic information available.
Sperling is an international authority on transportation technology assessment, energy and environmental aspects of transportation, and transportation policy. He is founder and director of the UC Davis Institute of Transportation Studies and a frequent advisor to policymakers, auto manufacturers, and the transportation fuel industry. ITS is the world’s leading academic program in clean vehicle fuels, technologies, and policy.
Joan Ogden, professor of environmental science and policy, was one of two CA&ES faculty to receive the 2007 Distinguished Scholarly Public Service Award. The honor is awarded to four faculty members each year by the Academic Senate for voluntary service in the scholar’s field of expertise. It recognizes professors for unpaid dissemination of information from their discipline to the public and nonprofit sector. Faculty receive the award for service activities such as advising public or nonprofit commissions, educating business, community groups, or the media, and giving testimony before government bodies.
Ogden, co-director of the Sustainable Transportation Energy Pathways Program at the Institute of Transportation Studies, does research on new energy technologies, with a focus on alternative fuels, fuel cells, renewable energy and energy conservation. She served on the Blueprint Plan advisory panel for the California Hydrogen Highway Network in 2005.
Joy Mench, professor of animal science and director of the Center for Animal Welfare, was one of two CA&ES faculty to receive the 2007 Distinguished Scholarly Public Service Award. The honor is awarded to four faculty members each year by the Academic Senate for voluntary service in the scholar’s field of expertise. It recognizes professors for unpaid dissemination of information from their discipline to the public and nonprofit sector. Faculty receive the award for service activities such as advising public or nonprofit commissions, educating business, community groups, or the media, and giving testimony before government bodies.
Mench does research on the assessment and improvement of animal welfare. Part of her research focuses on improving the housing, handling, and management of poultry, and she has helped develop voluntary standards for agricultural animals used in food production. Mench has also served on the Council on Accreditation for the Assessment and Accreditation of Laboratory Animal Care International, which helps promote humane treatment of laboratory animals.
Temple Grandin, a professor of animal science at Colorado State University, who has expertise on humane animal handling, recently visited the Department of Animal Science and the UC Davis M.I.N.D. Institute.
In the animal science department, she met with several groups of graduate students and faculty, provided a standing-room-only seminar, held a lecture/discussion with undergraduates at the Swine Center, and visited the animal facilities. She also gave two seminars on her experiences with autism for the M.I.N.D. Institute.
The animal science Web site has her seminar “Reducing Stress During Animal Handling” on video. The video can be viewed at http://animalscience.ucdavis.edu.
A campus memorial service for Shang Fa Yang, who died on February 12, will be held on Thursday, March 22, 4:00 to 5:00 p.m. at the International House, with a reception immediately following.
Yang was an internationally acclaimed professor emeritus in the Department of Plant Sciences (formerly vegetable crops), with expertise on the plant hormone ethylene, and how it impacts the postharvest biology of fruits, vegetables, and flowers. Among his many achievements, Yang was elected to the National Academy of Sciences and received the distinguished Wolf Prize in Agriculture.
Per the family’s wishes, contributions may be made to a UC Davis plant sciences student research fund in Dr. Yang’s memory. Checks should be made payable to the UC Davis Foundation in memory of Shang Fa Yang and sent to UC Davis Foundation, One Shields Avenue, University of California, Davis, CA 95616.
