Janet Caprile, UCCE advisor for Contra Costa and Alameda counties, and the Contra Costa County Agriculture Department have been awarded a 2016 IPM Achievement Award by the California Department of Pesticide Regulation for their cherry buckskin project.
Cherry buckskin disease has wiped out cherry production in several areas of California since it was first reported in 1931. In the 1980s, the disease became established in San Joaquin County. To prevent the establishment of the disease in neighboring Contra Costa County, a collaborative effort among UC Cooperative Extension, the county agriculture department and local cherry growers began in 1987.
Caprile trained UC Master Gardener volunteers to identify cherry buckskin disease symptoms and organized them to help perform an annual survey during harvest. Mid Valley Ag Services covers the cost of lab testing each year. The Master Gardeners and former coordinator Emma Conner first detected infected trees during the 2002 survey.
Caprile informed growers of the disease detection and worked with them to develop an aggressive IPM treatment and eradication program to prevent the establishment of this devastating disease. As a result of these efforts, the disease has been eliminated in Contra Costa County.
The 2016 Achievement Awards will be presented at a ceremony at the California Environmental Protection Agency headquarters on Jan. 26 in Sacramento.
The Renewable Natural Resources Foundation honored Doug Parker, director of the California Institute for Water Resources, with its Chairman's Award for Professional Service to the foundation.
In announcing the award, Robert D. Day, RNRF executive director, wrote to Parker: “You received the award because of your essential volunteer assistance in developing the program and identifying eminently qualified prospective speakers for RNRF's 2015 Congress on sustaining Wester Water. Plus, you launched the congress with an excellent opening address. We would not have had the program that we did without you.”
Parker is president of the Universities Council on Water Resources, an association of universities and organizations leading in education, research and public service in water resources. As UCOWR president, he serves on the executive council for NIDIS, the National Integrated Drought Information System, which maintains the Drought.gov website at https://www.drought.gov/drought.

Last year, the 4-H Youth Development Program and UC Master Gardener Program successfully participated in #GivingTuesday campaigns.
“Our goal for 4-H was to raise $10,000 and we exceeded our goal with donations totaling over $13,000,” said Andrea Ambrose, acting director of Development Services. 4-H programs in 17 counties participated. In Placer County, the robotics team got their friends and family involved to promote #4HGivingConfidence on social media, leading Placer County to collect the largest amount for the 4-H Youth Development Program.
Although not as widely recognized as the shopping events Black Friday and Cyber Monday, #GivingTuesday appeals to people swept up in the spirit of giving at the end of the year.
“#GivingTuesday is a wonderful opportunity for all ANR programs to augment their funding with private donations,” said Ambrose.
A website is being created with links to all of ANR's programs, Research and Extension Centers and extension offices. Donors will be invited to designate the program or location to which they wish to donate. The URL for the #GivingTuesday website will be announced in ANR Update soon.
ANR will provide a toolkit for county offices and programs to participate. It will include:
- A customizable letter to send to stakeholders
- Templates for “unselfies.” Donors may take photos of themselves holding an unselfie sign and share on social media how they are giving.
- Sample tweets and social media posts
- Sample thank you note
“We focused on fostering a good dialogue and facilitating co-learning among attendees,” said event co-chair Leslie Roche, assistant UC Cooperative Extension specialist in rangeland management. “We hosted university faculty, statewide CE specialists and academics, and county-based CE advisors—as well as local policymakers and leaders from non-governmental organizations and statewide programs.”
UC researchers who have successfully engaged in the public policy arena provided numerous models of linking research and policy. There were five key take-aways for scientists:
- Honest broker role – Present policymakers with various policy options, based on sound research. Have a clear understanding of the science behind your messaging. Use qualitative data to tell the story of the hard quantitative data.
- Active engagement – Be part of informational and oversight hearings. Empower communities to take action and foster community engagement.
- Build coalitions – Collaboration is imperative. Develop unexpected allies and foster long-term relationships, realizing it may take some time to bear fruit.
- Disseminate information – Share your data in user-friendly formats. Target local community, Legislature and state agencies to inform policies. Get your science into trainings and continuing education programs. Leverage your coalition to expand the circulation of your research results.
- Target messages – Develop a strong, concise message to deliver your research. Use an emotional connection – “Old-growth oak woodlands” versus “oak woodland.”
Throughout the conference, speakers highlighted the multiple levels of engagement for researchers in the policy arena, with different roles matching different needs – some take a center stage, while others play imperative behind-the-scenes roles.
Keynote speaker Jason Delborne, associate professor of science, policy and society at North Carolina State University, encouraged engaging the public. “Science is a social process,” he said, noting that community and public engagement is often key to successfully applying research to policy. Delborne also touched on the tension between expertise and democracy, commenting that we can't always resolve it and often we have to learn to live with this tension.
A diverse set of researchers shared their perspectives from experiences in engaging in policy. The panel included Thomas Harter, Robert M. Hagan Endowed Chair in Water Management and Policy and UCCE specialist in the Department of Land, Air, and Water Resources at UC Davis; Lorrene Ritchie, director of the UC ANR Nutrition Policy Institute; Mindy Romero, founder and director of California Civic Engagement Project at UC Davis Center for Regional Change; and Yana Valachovic, UCCE forest advisor and county director in Humboldt and Del Norte counties. They discussed the importance of building strong science-based programs, actively engaging local communities and building coalitions of support.
Guests from both government and non-government organizations who use research to shape policy shared their perspectives on translating science to decision-making.
“Science is the foundation for developing programs,” said Amrith Gunasekara, science advisor for the California Department of Food and Agriculture.
Tina Cannon Leahy, attorney with the State Water Resources Control Board, noted that policymakers and decision-makers are often looking for a clear, “black-and-white” answer, while for scientists, there is “no answer,” but rather information.
Anne Megaro, consultant to the California Senate Committee on Agriculture, and Rebecca Newhouse, consultant to the California Senate Environmental Quality Committee, both emphasized the importance of making sure science is accessible and digestible.
Juliet Sims of the Prevention Institute explained how her organization uses both published scholarly literature and community stories to effectively inform its advocacy platform.
Keynote speaker Rachel Morello-Frosch, associate professor in the Department of Environmental Science, Policy and Management at UC Berkeley, introduced the concept of moving from “translational research” to “transformational research,” a shift that requires deep community engagement in meaningful ways to effect policy change.
In the afternoon, four breakout sessions were offered: “Policy structures and opportunities for engagement” with Robert Waste, “Relational approaches to science communication and engagement” with Faith Kearns, “Putting it into practice–UC ANR case studies” with Dave Campbell, Clare Gupta and Lucas Frerichs, and “Navigating policy engagement: Education vs advocacy,” with Adrian Lopez and Kit Batten. These training modules helped participants build technical skills and analytical frameworks for successful policy engagement.
The Research to Policy Conference was a forum to exchange ideas and share perspectives, continuing to bridge the gap between science and policy communities. It challenged attendees to be open to new ways of thinking, shared innovative outreach methods and showcased how research can have an impact in the policy arena.
“The event brought cross-fertilization and co-learning between disciplines – nutrition, forest management, water quality – and there were common themes that resonated for all participants,” said event co-chair Gupta, assistant UCCE specialist in public policy and translational research.
VP Glenda Humiston wrapped up the policy conference by saying, "Good science is vital for good policy. It's great to see UC folks enhancing these skills to bring science together with policy."

Pourreza wins international prize for HLB detection
Newly appointed UC Cooperative Extension agricultural engineering advisor Alireza Pourreza has been awarded the 2016 Giuseppe Pellizzi Prize by the Club of Bologna, an honor presented every other year to the best doctoral dissertations focused on agricultural machinery and mechanization. The Club of Bologna is a world taskforce on strategies for the development of agricultural mechanization.
Pourreza, who earned his Ph.D. at the University of Florida in 2014, worked on early detection of Huanglongbing disease of citrus. Huanglongbing, an incurable disease that is spread by Asian citrus psyllid, has seriously impacted citrus production in Florida. The disease has been found in commercial and residential sites in all counties with commercial citrus.
Early detection allows growers to remove infected trees before the disease can spread to healthy trees. Currently HLB infection is confirmed when leaves with yellowing blotches are submitted for PCR testing, which is expensive and time-consuming. However, the yellowing can be also symptomatic of other conditions, such as nutrient deficiency.
"We discovered we could see the symptoms of Huanglongbing using a camera, a set of cross-polarizers and narrowband lighting before it is visible to the human eye," said Pourreza, who is based at the UC Kearney Agricultural Research and Extension Center in Parlier.
He said the yellow blotches on HLB-infected leaves are caused by starch accumulation.
"If we could detect abnormal levels of starch in the leaf, we could tell it is affected with HLB," Pourreza said. "Starch showed the ability to rotate the polarization plane of light. We used this optical characteristic to develop the sensing methodology."
Pourreza said the team has patented the technique and is working on developing a commercial product. He is seeking funding to continue the research in California, where, to date, HLB has only been detected in isolated Los Angeles neighborhoods. Asian citrus psyllid is found in important California commercial citrus production regions from the Mexican border to as far north as Placer County.
4-H Youth Development team wins national diversity award
4-H Youth Development advisors Dorina Espinoza, Russell Hill, Fe Moncloa and Keith Nathaniel and 4-H associate director Shannon Horrillo have won the National Extension Diversity Award for systematically enhancing the intercultural competency of 4-H personnel and others in California.
The award, given by USDA National Institute of Food and Agriculture (NIFA), Cooperative Extension System and the Association of Public and Land-grant Universities (APLU), honors the team for creating and using Intercultural Development Inventory© to shift organizational culture. This shift includes mutual respect, acceptance, teamwork and productivity among diverse people.
To meet the needs of a culturally and ethnically diverse youth population in California, they created a professional-development intervention for 4-H academics and staff. The Intercultural Development Inventory© is a cross-culturally generalizable, valid and reliable assessment of intercultural competence. Calling themselves the Intercultural Development Inventory Qualified Administrators, they applied the strategy over three years, providing 176 hours of intercultural communication feedback sessions, learning communities and regional conferences to enhance the intercultural competence of 65 4-H personnel.
Evaluations demonstrated that after the intervention UC 4-H Youth Development Program personnel had acquired skills and characteristics to become more culturally competent. The program has moved from focusing on similarities across diverse people that can mask deeper recognition of cultural differences to recognizing the complexity of dimensions of diversity.
The action plan and resulting positive change provides the potential to improve hiring and professional development nationwide by replication in other states. A summary of California's IDI professional development activities can be found in the National 4-H Latino Youth Outreach: Best Practices Toolkit, Professional Development.
The National Extension Diversity Award will be presented on Nov. 13 at the 129th APLU Annual Meeting in Austin, Texas.
