Rosenberg joins UCCE as regenerative agriculture farm advisor 
Sara Rosenberg joined UCCE on May 1 as a regenerative agriculture farm advisor for Mariposa, Merced and Stanislaus counties.
Her disciplinary focuses are agroecology, sustainable nutrient management, and extension research and methodology. Her past research centers on understanding the implications of diversification (with a focus on crop rotations and cover crops) for California rice systems. For her master's program thesis, she conducted a countywide assessment to learn from rice growers about their experiences with crop rotations and understand barriers to adoption, opportunities, and required resources for successful implementation. This two-year study engaged grower communities to help develop research goals for her Ph.D. studies.
Her doctoral research explored how different summer crop rotations affect multiple sustainability factors including soil health, crop yields, weeds, input use and economics. She also assessed different cover crop species performance in rice environments and their carbon and nitrogen contributions.
She earned a master's in international agriculture development and a Ph.D. in horticulture and agronomy from UC Davis.
Prior to working on her Ph.D., Rosenberg was an agriculture advisor in the Peace Corps for more than three years. She worked closely with smallholder farmers in West Africa, implementing conservation agriculture programs and increasing agricultural resilience in both annual crops and tree crops, mainly in the cashew forestry sector. In California, she has worked on farms for more than eight years, including running her own small, diversified farm in Woodland.
She is passionate about community-led development and using participatory research as a powerful tool for developing sustainable solutions. Her aim is to develop collaborative programming that will support a wide range of farm types, including commercial and small-scale, organic and conventional, annual crops, tree and vine crops, and livestock production systems.
She is developing a robust research program aimed at assessing farm sustainability impact across ecological, agronomic, social and economic factors. She will be collaborating with farmers to help overcome barriers to adopting regenerative practices and build their capacity to advance sustainability goals. Rosenberg also will be developing and promoting tested integrative management practices that increase climate resilience and ecosystem sustainability across diverse farming environments.

Pedroncelli named interim South Coast REC director 
Lindsey Pedroncelli started her new role as interim director of South Coast Research and Extension Center in Irvine on May 1.
Pedroncelli, former staff research associate for UC Cooperative Extension in San Diego County, will serve as the liaison between South Coast REC and the community. Her primary responsibility is maintaining or expanding current partnerships and identifying new opportunities for academic and programmatic collaboration. Additionally, she is responsible for securing funding, supervising education specialists and communicating the significance of the REC.
Pedroncelli first learned about UC ANR during graduate school at UC Riverside where she worked with Alexander Putman, UC Cooperative Extension plant pathology specialist. As a Ph.D. student, Pedroncelli studied a fungus (Macrophomina phaseolina) that kills strawberry plants and conducted research at the South Coast REC.
“California grows 90% of the nation's strawberries,” said Pedroncelli. “The fungus I was researching is economically important and since it is a somewhat new disease on strawberries, there isn't a lot of information on how to manage it.” She was particularly interested in how soil moisture can be applied as a management strategy.
Before earning a Ph.D. in plant pathology from UC Riverside, Pedroncelli completed her undergraduate degree in microbiology at Cal Poly San Luis Obispo.
In September 2022, Pedroncelli joined the UCCE office in San Diego County as a staff research associate and helped establish a small-scale urban agriculture demonstration site at the Flower Fields in Carlsbad. A collaboration with Eric Middleton, integrated pest management advisor for San Diego County, the project is designed to investigate the economic feasibility of growing specialty crops in urban areas.
“Orange County has become so urban, and it used to be an ag hot spot. I don't want people to forget that,” said Pedroncelli, who emphasized the importance of expanding the REC's educational programs and spreading awareness of its community impact.
Pedroncelli can be reached at lrpedroncelli@ucanr.edu and her Instagram handle is @theplantpathologist.

Gross named UCCE aquaculture specialist
Jackson Gross joined UCCE on Aug. 14, as an aquaculture specialist. His current research program aims to be at the forefront of environmental and production sustainability and ecological integrity. To achieve this vision, his research is focused into three distinct, yet overlapping applied research themes: aquaculture, invasion biology and environmental/ecological toxicology. This research usually addresses data gaps and provides scientific solutions, determined through rigorous experimentation, meeting the immediate biological and engineering needs of the aquaculture industry and natural resource community. His research is historically a mix of laboratory and field experimentation. However, there are many times where the research is not exclusively one or the other, but instead, a blend where controlled laboratory experimentation is brought into the field. Other areas of interest include aquaponic production systems.
Prior to joining UCCE, Gross worked at a private engineering firm evaluating the effects of anthropogenic activity on aquatic resources.

NAS elects Ronald and Zilberman as members
The National Academy of Sciences announced April 30 the election of 100 new members and 25 foreign associates in recognition of their distinguished and continuing achievements in original research. Forty percent of the newly elected members are women—the most ever elected in any one year to date.
Pamela Ronald, professor and geneticist in the UC Davis Department of Plant Pathology and Genome Center, and David Zilberman, a UC Cooperative Extension specialist and professor of agricultural and resources economics at UC Berkeley, are among the new members.
Ronald researches genes that control disease resistance and tolerance to environmental stress in rice, one of the world's most important crops. She is known for engineering flood-tolerant rice, for which she and her colleagues received the USDA 2008 National Research Discovery Award.
Zilberman is one of the most cited scholars in agricultural, environmental and resource economics. During the 1980s, his work served as the basis for several projects on the adoption of modern irrigation technology and computers in California agriculture. These studies demonstrated that farmers adopt new technologies when it makes economic sense and that extreme events, such as droughts or high prices, can trigger changes in farming practices. During the early 1990s, his research on pesticide economics and policy made the case against policies that called to ban pesticides, and advocated instead for policies that take advantage of the vast economic benefits that pesticides generate while using incentives to protect against environmental side effects. In January, Zilberman was awarded the 2019 Wolf Prize in Agriculture in recognition of his work developing economic models for fundamental problems in agriculture, economics and policy.
Dahlquist-Willard and Pathak honored by CalCAN
Two UC Cooperative Extension scientists were recognized for their contributions to the field of agriculture and climate change at the California Climate & Agriculture Summit at UC Davis on March 5, 2019.
Dahlquist-Willard helps keep small-scale, diversified farmers in business by providing support with marketing, regulatory compliance, processing of value-added products, water and energy efficiency, and integrated pest management. She has been a driving force behind increasing access by Hmong farmers in the Fresno area to California's State Water Efficiency and Enhancement Program (SWEEP). Dahlquist-Willard has promoted the program, provided thousands of hours of one-on-one, culturally relevant support to farmers on grant applications, and assisted with project design and installation. The farmers she has supported are now benefiting from water, energy and financial savings.
"There are large environmental problems to solve in the Central Valley, and it's time for a different conversation around farming there," Dahlquist-Willard said. "I feel that there needs to be a conversation in the middle to solve problems rather than a conflict-based approach."
Pathak is the chair of the UC Cooperative Extension Climate Change Adaptation Workgroup, which brings together scientists across the UC system to collaborate on research and extension projects related to climate change adaptation in California agriculture. Pathak is the lead author on an important and timely paper that was published in 2018 in the journal Agronomy. It synthesizes the impacts of climate change on California agriculture and offers directions for future research and implementation.
"We need more facilitated dialog with policy researchers and scientists on the science of climate change, and the implications of not taking action," Pathak said. "Given the scale of California agriculture and the pressure of climate change impacts, we need even more substantial funding for incentives for farmers and for research and tools, and we must integrate growers from the beginning of the process."
The summit, organized by CalCAN, brought together some of the state's foremost experts in agriculture — including farmers, agriculture professionals, researchers, advocates and policymakers — to grapple with the challenges of climate change and share knowledge about the opportunities facing the industry.
Mitloehner wins Borlaug CAST Communication Award
The Council for Agricultural Science and Technology (CAST) named UC Davis animal scientist Frank Mitloehner the 2019 Borlaug CAST Communication Award recipient. Mitloehner, a professor and UC Cooperative Extension air quality specialist in the Department of Animal Science, is the 10th recipient of this award.
“I'm honored to be selected by CAST, an organization I've long admired, and to be in the company of so many recipients who have inspired me during my career,” Mitloehner said. “Being recognized with the Borlaug CAST Communication Award is not only a high honor, it's an affirmation of the importance of sharing research and academic pursuits well beyond labs, classrooms and universities.”
CAST bestows the award annually to a nominated expert in the agricultural, environmental or food sectors. The nominee must show remarkable communication skills through various types of media with the purpose of advancing science in the public policy sector.
Mitloehner's nominators state he reaches beyond academia to inform experts and various members of the public around the globe about animal agriculture's influence on greenhouse gas emissions. His goal is to change societal views about the influence of animals on our climate through various channels of communication.
“His involvement as a communicator and scientist at the national and global levels has put him and his message in a strategic position to share and influence policy,” said one of Mitloehner's nominators.
Numerous like-minded agencies and institutions have reached out for his guidance on timely and relevant issues regarding animal agriculture's impacts on air quality, including chairing a committee for the Food and Agriculture Organization of the United Nations.
Since he joined UC Davis in 2002, Mitloehner has amassed more than 800 presentations focused on animal agriculture through various speaking events such as conferences and professional meetings. He has contributed to national news stories published by CNN, PBS, Newsweek, The Washington Post and other media outlets.
Mitloehner does not shy away from social media either. He began tweeting with the handle @GHGGuru in April 2018 and his Twitter account has more than 7,000 followers. In late 2018, Mitloehner launched GHG Guru Blog, a personal website with the goal of delivering the “latest, most accurate research” focused on the intersection between animal agriculture and the climate.
“Science for science's sake has no role in making our world more sustainable,” Mitloehner said. “Sharing what we know — and backing it up with facts — leads to discussions and solutions,” Mitloehner said.
The Borlaug CAST Communication Award is sponsored by the CropLife Foundation. CAST announced the 2019 BCCA recipient at the USDA Whitten Patio in Washington, D.C., on April 16.
The award will be presented held during a side event at the World Food Prize Symposium on Oct. 16. – UC Davis
Fung and Staskawicz elected Royal Society members
The Royal Society of London, the oldest scientific academy in continuous existence, announced their newest fellows and foreign members April 16, among them two UC Berkeley College of Natural Resources faculty.
The newly-elected CNR foreign members are climate scientist Inez Fung and plant biologist Brian Staskawicz. Fung and Staskawicz are among 51 new fellows, 10 new foreign members and one new honorary member.
“Over the course of the Royal Society's vast history, it is our fellowship that has remained a constant thread and the substance from which our purpose has been realized: to use science for the benefit of humanity,” said society president Venki Ramakrishnan. “This year's newly elected Fellows and Foreign Members of the Royal Society embody this, being drawn from diverse fields of enquiry – epidemiology, geometry, climatology — at once disparate, but also aligned in their pursuit and contributions of knowledge about the world in which we live. It is with great honor that I welcome them as Fellows of the Royal Society.”
The learned society dates from 1660 and today is the U.K.'s national science academy and a fellowship of some 1,600 of the world's most eminent scientists.
Fung, a professor of earth and planetary science and of environmental science, policy and management, models the processes that maintain and alter the composition of the atmosphere and, hence, the climate.
Staskawicz, a professor of plant and microbial biology and a co-director of the Innovative Genomics Institute, studies plants' innate immunity with the goal of engineering disease resistance in agricultural crops.
