Flavell remains interim director of Sierra Foothill REC

Dustin Flavell

An internal search to fill the director position at Sierra Foothills REC was conducted during November-December 2020. Unfortunately, no applications were received. UCANR leadership and UC Livestock & Natural Resources academics are exploring options to provide sustained leadership for SFREC.

In the meantime, SFREC superintendent Dustin Flavell will continue to oversee the center. Flavell has served as interim director since September, when Jeremy James left UC ANR to become department chair of Natural Resources at Cal Poly San Luis Obispo.

DOE honors Sanchez for carbon removal research

Dan Sanchez

The U.S. Department of Energy (DOE) granted a Secretary of Energy Achievement Award to a team including UC assistant Cooperative Extension specialist Daniel Sanchez and Ph.D. candidate Bodie Cabiyo in the Department of Environmental Science, Policy, and Management at UC Berkeley.

Sanchez and Cabiyo's team "Getting to Neutral Carbon Emissions" was selected for their outstanding service and research contributions, both to the agency's mission and the benefit of the nation, in greenhouse gas emissions reduction scholarship.  

The team's final report, titled “Getting to Neutral: Options for Negative Carbon Emissions in California,” provides a comprehensive study of technologies that remove carbon dioxide from the atmosphere. It offers frameworks for developing public policy and legislative action based on scientific data to help California achieve carbon neutrality by 2045 or sooner. Sanchez and Cabiyo contributed research to help estimate the amount of forest biomass that can be used in negative emission pathways, as a result of managing 1 million acres of forest each year. They used economically driven models to identify the most cost-efficient forest management strategies for the team's Forest Carbon Plan goals. 

The award is one of the highest internal, non-monetary recognitions that DOE employees and contractors can receive. 

Mitchell receives No-Till Innovator Research & Education award

Jeffrey Mitchell, UC Cooperative Extension specialist, received the No-Till Innovator Research & Education award for his commitment to the advancement of no-till farming systems.

Mitchell, who is based at Kearney Agricultural Research and Extension Center, has been a pioneer in design, research, knowledge generation and extension in conservation cropping systems in California. With his dedication, these conservation cropping systems are now beginning to be gradually adopted in the state and are receiving much attention from growers, extension, industry, educational institutions, state and federal government agencies, and non-governmental agencies, says Anil Shrestha, chair of the department of Viticulture and Enology at Fresno State University.

Initially, Mitchell established the UC Conservation Tillage Workgroup that was primarily focused on no-till systems. Later, he expanded the workgroup and established the Conservation Agriculture Systems Initiative (CASI) group with a broader conservation systems approach. CASI won the No-Till Innovator Award in 2018. 

Mitchell expanded his work to vegetable crops and is among the first in the U.S. to work on these systems combined with precision irrigation technology. Mitchell organizes the CASI Workgroup Field Days and Demonstrations at the UC West Side Research and Extension Center. 

An important part of Mitchell's research and education efforts has emphasized evaluations of the impacts and tradeoffs that reduced disturbance tillage and cover cropping have on soil and cropping system function. 

Based on a long-term study dating to 1999, Mitchell worked with a team that documented that no-till and cover crop practices in sorghum, cotton, corn, wheat and tomato could not only maintain productivity, but also greatly impact a number of important soil quality indicators — including higher soil carbon and nitrogen, aggregation and infiltration. This work has documented that significant positive changes have occurred even in the arid, irrigated soils in the San Joaquin Valley. 

Wang honored for olive research

Selina Wang evaluates oil quality.

Selina Wang, research director at the UC Davis Olive Center and UC Cooperative Extension specialist in the UC Davis Department of Food Science and Technology, recently received the Olive Wellness Institute's inaugural award for achievement in olive science research.

Wang joined the Olive Center as a postdoctoral researcher in 2010 and became research director in 2011, leading the center's research efforts in olive oil quality, authenticity and standardization. She took on her Cooperative Extension duties in 2018. “I still do the work I've been doing with olives and olive oil, but now I cover all the crops that are important for California,” she said.

Research from the Olive Center contributed to the scientific basis for the establishment of California grade and labeling standards for olive oil, refined-olive oil and olive-pomace oil. Under the standards, producers of greater than 5,000 gallons per year must test every lot of oil for quality, thereby instilling confidence in consumers.

Wang said she looks forward to continued research on maximizing quality, health benefits, yield and sustainability — in the field and in processing. “We've made a tremendous amount of progress in the past decade, and there's more work to be done, especially in response to climate change,” she said. “I will continue extension with the growers and processors and education with the students at UC Davis who are the future leaders.”

Dan Flynn, the recently retired Olive Center director, nominated Wang for the award. “Dr. Wang stands among the very best people I have worked with,” he said. “Her independent and significant research achievement, skill at attracting financial backing and resources, ability to inspire students, robust work ethic, dedication to the public interest and exceptional interpersonal skills place her among the noteworthy olive scientists globally.” – UC Davis News and Media Relations 

Khan elected to national hydrologic science board

Safeeq Khan

Safeeq Khan, assistant UC Cooperative Extension specialist for water and watershed sciences based at UC Merced, has been elected to the board of directors for the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI).

Gosliner to serve on Farm to School Working Group subcommittee

Wendi Gosliner
Wendi Gosliner, project scientist at the Nutrition Policy Institute, has been invited to work on a California Department of Food and Agriculture subcommittee of the California Farm to School Working Group by CDFA Secretary Karen Ross and First Partner of California Jennifer Siebel Newsom.

Gosliner was recommended to participate in the Health Systems Data subcommittee because of her experience in measuring impact for food systems projects.

As a subcommittee member, Gosliner will help create a unified vision for the future of farm to school in California. The group will meet January 2021 through October 2021, culminating in the publishing of a “Roadmap to Success” for California's farm to school movement.

“Our state leaders recognize the need to transform our food system into one that is climate-smart, equitable, resilient, reflective of all of California's diverse cultures, and accessible to all,” said Ross and Siebel Newsom. “We know school nutrition is a key element of this transformation, and a recent $10m budget allocation from Governor Newsom shows the state is making a serious effort to expand its impact.”

UC ANR and AgStart receive $500,000 to cultivate the VINE

The Verde Innovation Network for Entrepreneurship will connect entrepreneurs statewide to resources to commercialize a new product or start a business.

California is constantly being challenged by pest invasions, obesity, labor shortages, water scarcity, food insecurity, climate change and more. To accelerate the development and adoption of technologies that address these challenges and advance food, agriculture and natural resources in California, UC Agriculture and Natural Resources and AgStart will receive a $500,000 grant from the U.S. Economic Development Administration (EDA) to cultivate the Verde Innovation Network for Entrepreneurship (the VINE).

Like a grapevine, the VINE will connect existing clusters of innovation across California and link entrepreneurs with mentors, advisors, collaborators, events, competitions, education and other services to turn good ideas into products and services people can use. 

“We want to make sure every Californian has the support system to take a novel idea and commercialize a new product or start a new business,” said VP Glenda Humiston. “They don't have to be a university inventor, they could be a farmer or a young person.”

John Selep of AgStart, left, works with Olivier Jerphagnon and Kevin Langham of Powwow Energy, which uses electric utility smartmeters to help growers measure irrigation water use.

AgStart itself was established with an EDA i6 Challenge grant to assist agriculture and food technology entrepreneurs in the Sacramento Valley region. Since 2012, AgStart has supported more than 58 entrepreneurs and their companies.

“In 2016, of the 16 entrepreneurial companies that AgStart assisted, eight resided outside our region, and leveraged AgStart's program to make connections into our Sacramento Valley region,” said John Selep, president of AgTech Innovation Alliance, AgStart's sponsor. 

“The VINE will expand this AgStart model of connecting entrepreneurs to the resources they need to be successful, to enable entrepreneurs residing anywhere in California to connect to the clusters of resources, contacts, mentors and potential partners that have emerged across the state,” said Selep.  

“The VINE is really exciting because of its potential to unite all the regions of California in an innovation ecosystem for food, agriculture and natural resources,” said Gabe Youtsey.
Gabriel Youtsey, UC ANR chief innovation officer, said the VINE won't recreate the wheel. 

 “There are many wonderful regional innovation hubs in food, agriculture and natural resources so we plan to bring value by amplifying their efforts, connecting regions and organizations into a more cohesive ecosystem, and bringing value-added resources that ultimately benefit all Californians through the innovations affecting our economic prosperity, food supply and environment,” Youtsey said.

UC Cooperative Extension specialists and advisors, who work in every county, can provide insight into real-world conditions that entrepreneurs should consider in the development stage. UC ANR's nine research and extension centers can provide locations to field-test products and demonstrate their effectiveness. For example, start-up Blue River is testing its technology by flying a drone over sorghum crops to collect data at the UC Kearney Agricultural Research and Extension Center in Parlier.

2017 Apps for Ag hackathon winners Sreejumon Kundilepurayil and Vidya Kannoly are getting help from UC ANR to commercialize their smartphone app.
“The VINE is really exciting because of its potential to unite all the regions of California in an innovation ecosystem for food, agriculture and natural resources,” said Youtsey. “Not only will it help bridge the Silicon Valley and Bay Area with California's food-producing valleys, but it will bring opportunities for our innovators and entrepreneurs in rural communities in every part of California to participate.”

For the last two years, UC ANR has hosted the Apps for Ag hackathon and has introduced the winners to mentors, tech industry advisors, farmers, funders and legal experts who can advise entrepreneurs on business structure.

The VINE, which is working with UC Davis Innovation Institute for Food and Health and Valley Vision, is being structured to complement other efforts to establish food, agriculture, and natural resources incubation and innovation resources in cluster locations around the state, such as the BlueTechValley Regional Innovation Cluster, the Western Growers Innovation & Technology Center, UC Merced's VentureLab and others.

Youtsey and Selep are seeking more VINE partners with expertise across the business spectrum.

“If our vision is successful, the VINE will make California the most fertile region in the world for entrepreneurs in ag and food technology to establish themselves, to prosper and grow,” Selep said.

UC ANR Staff Assembly Updates

Senior delegate Jeannette Warnert, left, and junior delegate LeChé McGill represented UC ANR staff at the Council of UC Staff Assemblies meeting in San Diego.

Ambassadors Meeting

The UC ANR Staff Assembly Council will hold a Staff Assembly Ambassadors meeting at the ANR Building in Davis on Oct. 10. The engagement will provide an opportunity for ambassadors to visit and network with colleagues and review Staff Assembly priorities. Additionally, they will discuss opportunities for staff to become more involved in addressing staff concerns and furthering organizational goals.

UC ANR Tote Bags

UC ANR Staff Assembly tote bag

In an effort to help spread the word about UC ANR Staff Assembly, all Staff Assembly members will receive a We Are UC ANR Staff Assembly tote bag. Members of the UC Staff Assembly include all ANR staff, whether employed by the county or the university, represented by a union or not represented. UC ANR Staff Assembly Ambassadors are the points of contact for distributing the bags at each office.

CUCSA Fall 2017 Meeting

UC San Diego was the site of the CUCSA (Council of University of California Staff Assemblies) Fall 2017 Meeting Sept. 6-8. The meeting included a team building exercise, work group action planning, post retirement health benefit discussions and a review of UC Employee Engagement Survey results. UC ANR junior delegate LeChé McGill and senior delegate Jeannette Warnert represented UC ANR staff at the meeting.

On the subject of potential changes to post-retirement health benefits, CUCSA chair Lina Layiktez provided the summary below and links for more information.

Proposed change to post-retirement health benefits
The proposed action item for the July 2017 Regents meeting was to remove the 70 percent floor on the UC contribution to retiree health benefits and place a cap of 3 percent on year-over-year increases to UC costs. This is a policy change to offset the accounting rule changes required in "GASB 75." GASB 75 requires that the full actuarial value of other postemployment benefits (OPEB) be included on the systemwide balance sheet. This means that UC will have a perceived “new” liability of $21 billion, which would affect the system's overall credit rating. A hit to the UC's credit rating has obvious impacts to financing for the university.

The “new” GASB 75 requirement definition is subject to interpretation, since it was already a liability that was disclosed in previous year's financials. The value of this liability under current assumptions/retiree rules is approximately $21 billion. The current assumptions are being driven by the number of retirees in the system plus the number of potential retirees (active staff and faculty) and how much it would cost the system in health-care costs should the current employees retire today.

What does this all mean?
By removing the floor and capping UC's costs, the university effectively transfers rising health-care premiums to retirees. The assumed rate of health-care cost increase is 7 percent. Over the course of 20 years this would flip the proportion that UC pays to ~30 percent and the retiree to ~70 percent. The 70 percent floor was designed to provide some stability to retiree health-care costs.

What do we see happening?
Many UC employees choose to retire after calculating their retirement income. This is necessary because, except for Cost of Living Adjustments (COLA), there is no way for retirees to increase their income from the university. So when out-of-pocket health-care costs go up for retirees, this eats into their living expenses. There are already retirees and survivors of retirees who have to choose between health-care costs and food. To suddenly remove the 70% floor exacerbates this problem.

What can you do?
The campus staff assemblies are collecting feedback locally and sharing this up to the Council of UC Staff Assemblies (CUCSA), who will be coordinating a response to the UC President and/or Board of Regents. We are also working on a list of questions that include queries, such as what OPEB would look like if it grandparented current employees and implemented the changes to future retirees? What does this mean for retention of employees with 10 to 20 years of service?

The most powerful and helpful thing for us now is to hear about your personal concerns and how this impacts you. Would no OPEB mean you are less likely to retire from the UC system and take a job elsewhere for more money now? Will you have to postpone your retirement if, in retirement, you will have to pay a greater portion of your OPEB than you had planned for under the current plan?

Share your questions and stories with us on the UC ANR Staff Assembly website.

What's next?
Fortunately, the July agenda was revised and this item was moved to the November meeting agenda. Moving the item to November will allow for more consultation and discussion. It is unknown what approach the UC Office of the President (OP) will take to solicit feedback and engage in discussion. But as that information becomes available, we will make sure to share it broadly. We are hopeful that CUCSA (and therefore a voice of staff) will be included in the discussions and that OP will convene a task force representing all parties that will be affected by the proposed changes. Stay tuned.

Click here for the original July Regents Meeting Agenda Item (F7), which was then revised to remove the discussion on the 70 percent floor.

The immediate past chair of the systemwide Academic Senate, Jim Chalfant, has already written a letter to the UC President on this issue. You can read it online here: http://senate.universityofcalifornia.edu/_files/reports/JC-JN-Retiree-Health.pdf.

We can work collectively to inform and educate staff on this important matter. We are stronger together and the more voices that participate, the louder the message will be to those making the decisions that affect all of us.

UC ANR human resources director John Fox also said one important point that isn't addressed in the CUCSA summary is Medicare coverage. “When a UC retiree enrolls in Medicare, the monthly medical premium costs are significantly reduced (both for the retiree and for UC). Much of the future liability that UC is trying to control (and the risk of high monthly costs for the retirees) is during the time between retirement from UC and the start of Medicare eligibility (typically age 65).”

If you would like to share your stories or post a comment on this proposed change, please fill out the form on the UC ANR Staff Assembly website. We will share comments and stories from UC ANR with CUCSA leadership, who will compile it with information from other campuses to share with the UC President and UC Regents.

Carbon Neutrality Initiative fellows seek to reduce our carbon footprint

UC Berkeley doctoral candidates Jose Daniel Lara, Allegra Mayer and Carmen Tubbesing, UC ANR's Carbon Neutrality Initiative (CNI) fellows for 2017-18, are studying new sources of renewable energy and strategies to cut carbon emissions.

The UC President's Carbon Neutrality Initiative Student Fellowship Program, established in 2015, funds student-generated projects that support the UC system's goal to produce zero-net greenhouse gas emissions by 2025.

Each fellow will receive $3,000 to fund their sustainability-themed project.

The 2017-18 CNI fellows:

Jose Daniel Lara
Jose Daniel Lara of San Jose, Costa Rica, is a first-year Ph.D. candidate in the Energy and Resources Group at UC Berkeley. Lara aims to determine the feasibility of producing electric power from dead trees. To analyze the resources available from tree die-off, he will develop a method to simulate harvesting of dead trees and evaluate the cost of harvesting dead biomass for electricity production. These results will inform policies regarding the use of biomass feedstocks to generate electric power and help mitigate the consequences of massive tree die-offs in forest communities throughout California.

Allegra Mayer
Allegra Mayer of Palo Alto is a fourth-year Ph.D. candidate in the Department of Environmental Science, Policy, and Management at UC Berkeley. Mayer is studying the potential for storing carbon in grassland soils across California to reduce global temperatures. Allegra will combine laboratory incubations with a state-of-the-art carbon model (DayCent) to measure and predict the effect of compost applications on grassland soil. She will then apply these results to quantify the potential change in grassland productivity and soil carbon storage associated with compost amendments. This will allow her to model the impact of climate change on the carbon cycle at these sites. 

Carmen Tubbesing
Carmen Tubbesing of Redmond, Wash., is a fourth-year Ph.D. candidate in the Department of Environmental Science, Policy, and Management at UC Berkeley and a fellow in the Graduate Student Program in Extension. The recent California drought led to a massive tree die-off, particularly in the southern Sierra Nevada, that will have long-term impacts on forest carbon storage. To gain a better understanding of the impact of carbon from dead trees, Tubbesing will calculate forest carbon transfers from live tree pools to dead pools between 2012 and 2016.
