Clarice Turner: Almond Growers Dig In to Find What the Best Practices Are

There is a Halo that Surrounds Almonds

By Patrick Cavanaugh, with the Ag Information Radio Network

Clarice Turner, a ninth-generation California farming family will take the reins of the Almond Board of California at the end of this month, after Richard Waycott steps down after 21 years.

Turner comments on how she prepared for this job, traveling throughout the state in listening sessions with growers and others in the industry. “It’s interesting as I talk to people outside the industry, you realize the halo that almonds have, and how we are so revered as being the leading edge in so many things. And talking to growers you hear that reinforced from people who want to be 100 percent organic to biodynamic,” said Turner.

“Growers told me that they have been farming the same ground for four generations and we have been taking care of the soil, and it is not certified to do any of that, but we know what we know because we have generations to protect. We want to hand this down to our families that will come beyond us,” noted Turner. “So, their care and stewardship are there and they want to dig in to find out what the best practices are.”

And Turner credited almond growers with something very special regarding bees. “This was astounding to me when you think about bees, 86 percent of the bee-friendly certified farms are almond orchards. It’s incredible, all the things that are already happening because it’s the right thing,” she said.

Clarice Turner Will Take the Reins of the Almond Board of California Soon

Turner Comes from A Ninth Generation California Farming Family

By Patrick Cavanaugh with the Ag Information Radio Network

Meet Clarice Turner, who will be the new President and CEO of the Almond Board of California at the end of this month. She is following Richard Waycott who is stepping down as the President and CEO of the Almond Board following 21 years of service.

She comments on her new role at the Almond Board of California. “I could not be more pleased to be in this role. My passion for ag stems a long time back to 1773, that’s nine generations of being a Californian family, and my family has farmed so many different crops over the years as things come and go,” noted Turner.  “I used to do peaches in Modesto, but try to find a stone fruit in Modesto now, there are not too many of them.”

“But it’s a great pleasure to have this role because I’m so passionate about agriculture in the state and I’m worried about it honestly, and the opportunity to be able to make a difference on behalf of a lot of agriculture because we represent such a huge category within the state and frankly within the U.S,” she said.

“That’s a great honor, and pleasure, and I’m not sure exactly how we’re going to go about it yet, but I’m learning like crazy,” noted Turner.  “And what I do know is that there is an amazing group of people out there who care deeply and have lots of ideas, and we are very fortunate to have leaders in the industry who want to collaborate and work together. That gives me a lot of hope and fuels my passion to be able to help take us forward,” she noted.

Key Climate Data Added to Enhance Grower Decision-Support Tool

By Pam Kan-Rice UCANR

Free CalAgroClimate tool helps growers protect crops from frost and extreme heat

California farmers can see how climatic conditions that may affect agriculture are changing in their regions by using CalAgroClimate so they can make strategic changes. Nine new agriculturally important climate indicators have been added to the decision-support tool created by UC Cooperative Extension and U.S. Department of Agriculture scientists.

These new tools use a high-resolution climate dataset called PRISM to provide location-specific or county-aggregated long-term trends in agroclimatic indicators from 1980 to last year. These new agroclimate indicators include Frost Days, Last Spring Freeze, First Fall Freeze, Freeze-Free Season, Tropical Nights, Hot Days, Extreme Heat Days, Heatwaves and Diurnal Temperature Range (see definitions below). These indicators were derived from a study published in the journal Agronomy.

All of the new tools are free and available on CalAgroClimate for anyone to access.

“Frost-related tools such as Frost Days, Last Spring Freeze, First Fall Freeze, and Freeze-Free Season can help farmers and agricultural clientele make informed long-term choices,” said Tapan B. Pathak, UC Cooperative Extension specialist in climate adaptation in agriculture based at UC Merced, who is leading the CalAgroClimate project.

“For instance, if you are planning to invest in a frost sensitive crop in your region, these indicators can provide valuable information on whether frost risk has changed over time and whether it is less risky to make such an investment,” he said. “Wine grapes, for instance, are very sensitive to frost. Although not all frost events are damaging, understanding long-term trends in frost can help in making long-term strategic decisions such as whether to invest in frost protections.”

Another set of new agroclimatic indicators, on CalAgroClimate – Tropical Nights, Hot Days, Extreme Heat Days, Heatwaves and Diurnal Temperature Range – are based on higher maximum and minimum temperatures. Tropical Nights, for instance, calculates total number of nights when overnight temperatures exceed 68 F. More frequent tropical nights can increase crop respiration rates and can be detrimental for fruit quality and quantity, increase the risk of damage from pathogens, and potentially impact fruit set and yield.

Knowing how trends are evolving over time can assist growers in managing their crops to reduce risks. Similarly, growers can easily look at trends related to heat – hot days, extreme heat and heatwaves – on CalAgroClimate to assess their options on what they need to do to be adaptive. In the short term, growers may put up shade or for longer term, choose varieties that are more heat-tolerant.

“In recently published work, one of the farmers in the Central Valley told us, ‘When you really see so much difference in a short amount of time in your immediate area…we would have to look at that and say, well, we’re going to have to adapt varieties because this is a 20- or 25-year planting and we’re going to have to find crops or varieties that will adapt to that,’” Pathak said.

Another farmer told us, “Knowing what’s going to happen or at least having a good idea, if you know something’s going to be become or won’t be viable, then obviously you’re going to try to phase that out, and phase in something that’s better suited.”

Pathak added, “The new agroclimatic indicators on CalAgroClimate provide a reality check on how conditions are changing in short and long-term, what it means for farmers and to assist them on deciding what they need to do to be adaptive. These tools will greatly benefit farmers and agricultural clientele in assessing risks and making informed decisions.”

Other collaborators include Steven Ostoja and Lauren Parker of the USDA California Climate Hub, Prakash Kumar Jha of UC Agriculture and Natural Resources and Robert Johnson and Shane Feirer of UC Agriculture and Natural Resources’ Informatics and Geographic Information Systems.

Definitions of AgroClimatic Indicators:

Frost Days are days in a year with minimum temperature below or equal to 32F.

Last Spring Freeze is the latest day in spring when minimum temperature is below or equal to 32F.

First Fall Freeze is the earliest day in fall when minimum temperature falls to 32F or below.

Freeze-Free Season is the time between the last spring and first fall freeze, represented by the number of consecutive days in a year without freezing temperatures.

Tropical Nights are number of nights when temperatures exceed 68F.

Hot Days are the days per year with maximum temperature exceeding 100 °F.

Extreme Heat Days are the number of days per year with maximum temperatures warmer than the 98th percentile of historical summer maximum temperature for the selected location.

Heatwaves are events that occur when extreme heat lasts for at least three consecutive days.

Diurnal Temperature Range is the difference between daily maximum and minimum temperatures.

Wet Orchard Floors Could Cause Phytophthora Problems

By Patrick Cavanaugh, with the Ag Information Network

With all the rainfall in many parts of the state, standing water in orchards could be a problem to those trees as it could cause anaerobic situations. Katherine Jarvis-Shean is a UCANR farm advisor based in Yolo County with additional coverage in Solano and Sacramento counties. She noted problems if that water stays standing deep in orchards.

The danger zone comes after, say four days or so, in terms of having anaerobic responses. Certainly, if you’re sitting in moisture and saturated soil for more than 24 hours, you’re in the danger zone with phytophthora infections. Which is a serious fungal disease,” she said.

“And we’re even looking at some water lines above the root zone crown. So then you get water just on a pure almond scion that can, it’s very vulnerable to phytophthora, especially aerial phytophthora,” noted Jarvis-Shean.  “It’s a good year to stay on top of your phytophthora management in terms of phosphite, and other potential phytophthora treatments for those wet orchards,” she said.

U.S. EPA Proposed Changes to Rodenticide Labels for Agricultural Use: Opportunity for Public Comment

By Roger A. Baldwin, Professor of Cooperative Extension, UC Davis and Niamh Quinn, Cooperative Extension Advisor, UC South Coast Research and Extension Center

Rodents cause substantial damage and health risks in agricultural productions systems through direct consumption of fruit, nuts, and vegetative material; damage to the plant (e.g., girdling of stems and trunks); by providing a food safety hazard from contamination; damage to irrigation infrastructure; damage to farm equipment; burrow systems posing a hazard to farm laborers; posing a health risk through potential disease transmission; and increased soil erosion by water channeling down burrow systems, among other potential damage outcomes. They also cause substantial damage and food contamination risks in livestock holding facilities, food processing facilities, barns, and other agricultural-related structures. As such, effective management is needed to minimize these risks. The use of rodenticides is often considered the most efficacious and cost-effective tool for managing rodent pests, and as such, it is often included in Integrated Pest Management (IPM) programs designed to mitigate rodent damage and health risks. Given the significance of rodenticides in managing rodent pests, it is important to know that the U.S. EPA has recently released a list of Proposed Interim Decisions (PIDs) for public comment that, if approved, will substantially alter if and how rodenticides may be used to manage rodent pests in the near future. As such, we felt it was important to inform California’s agricultural producers as to the extent of these proposed changes, and if you are so inclined, we have provided a link for you to provide public comment on the PIDs, as well as links to contact your Senate and Congressional representatives to ensure your opinion is heard.

All rodenticides are currently under review. These include first-generation anticoagulants (FGARs; chlorophacinone, diphacinone, and warfarin), second-generation anticoagulants (SGARs; brodifacoum, bromadiolone, difethialone, and difenacoum), zinc phosphide, strychnine, bromethalin, and cholecalciferol. Of these, only FGARs, zinc phosphide, and strychnine have labels for use against field rodents (e.g., ground squirrels, pocket gophers, voles, rats, and mice found in agricultural fields), but not all of these active ingredients can be used for all rodent species. As always, it is imperative to fully read a rodenticide’s label before determining if it is appropriate for use against a particular species and in a specific situation. That said, the following are some significant changes that have been proposed that you should be aware of. Other potential changes have been proposed as well, so please check out the PIDs for additional details (linked at the end of this document).

1. All rodenticides for field applications will become restricted-use products. This means that applicators will need to be certified to use restricted-use products in these settings. They will also have increased reporting requirements for their use.
2. Above ground applications would be eliminated in rangeland, pastureland, and fallow land. This is a substantial deviation, as many/most applications in these areas have traditionally been through broadcast applications or spot treatments. This change would leave only bait stations for ground squirrels and voles.
3. Within-burrow applications of FGARs will generally not be allowed in croplands during the growing season. This would eliminate FGAR application for pocket gophers for much of the year, and would eliminate it for all uses in some crops (e.g., citrus and alfalfa in certain areas of the state).
4. Carcass searches will be required every day or every two days (starting 3-4 days after the initial application), depending on the product used and where applied, for at least two weeks after the last application of the rodenticide. When carcasses are found, they must be disposed of properly. Any non-target mortalities must be reported to the U.S. EPA. Collectively, this will require a major increase in labor, potentially making rodenticide applications impractical in many settings.
5. Extensive endangered species designations are anticipated that will limit or eliminate the potential to apply rodenticides. This could have large-scale impacts, although the full extent is not known at this time.
6. New labels will require the use of a PF10 respirator and chemical resistant gloves during application. This is a substantial change for some rodenticide labels, requiring fit testing for all applicators, with the requirement of respirators ultimately making rodenticide application more physically challenging.

Additional details on these proposed changes can be found at the following websites:

1. Anticoagulant PID: https://www.regulations.gov/document/EPA-HQ-OPP-2015-0778-0094
2. Zinc phosphide PID: https://www.regulations.gov/document/EPA-HQ-OPP-2016-0140-0031
3. Strychnine PID: https://www.regulations.gov/document/EPA-HQ-OPP-2015-0754-0025
4. Bromethalin and cholecalciferol PID: https://www.regulations.gov/document/EPA-HQ-OPP-2016-0077-0024

As mentioned previously, these proposed changes are likely to have a substantial impact on the use of rodenticides in agricultural settings. However, these changes are currently open for public comment. If you would like to comment on these proposed changes, the required links and useful guidance can be found at the following website: https://responsiblerodenticides.org/.

You may also comment on these proposed changes to your Senate and Congressional representatives. If you are unsure who they are or how to contact them, check out: https://www.congress.gov/contact-us.

The deadline for making comments to the U.S. EPA is unfortunately short, with a final deadline of February 13, 2023. Therefore, you will need to provide your comments in short order.

As an academic coordinator, Ikendi will work with farmers and ranchers, state and federal agencies, campus-based academics and Cooperative Extension academics across the state to implement climate-smart agriculture education through workshops and training. He will develop outreach materials such as curricula and fact sheets.

Before joining UC ANR, Ikendi worked at Iowa State University as a postdoctoral research associate on a project to establish core concepts to improve graduate plant-breeding education, curriculum development, and monitoring. He also worked for the Center for Sustainable Rural Livelihoods and Iowa State University’s Uganda Program in Uganda, where he developed performance tracking indicators, conducted the annual evaluation, and developed privacy data protection documents. As an intern with ISU Extension and Outreach, he assisted the county outreach coordinators with delivering research-based educational programming to promote positive youth development.  

Ikendi earned a Ph.D. in agricultural extension education and dual master’s degrees in community and regional planning and sustainable agriculture from Iowa State University. He earned a bachelor’s degree in agribusiness management from Makerere University, Kampala in Uganda. 

Ikendi is based at UC Merced and can be reached at sikendi@ucanr.edu

Reidy named statewide postfire academic coordinator

Katie Reidy joined UC ANR on Dec. 5 as the statewide postfire academic coordinator. She will be overseeing a postfire forest resilience education program for private forest landowners. Reidy will coordinate weekly educational workshops held on Zoom with lessons catered to specific ecosystems, and collaboration with local agencies to promote post-fire education. The goal is to help fire-affected communities begin the process of reversing the ecological, economic and environmental impacts of fire. 

Reidy grew up in Chicago and received an undergraduate degree from University of North Carolina, Asheville. In 2016, she became an environmental educator at Yosemite National Park. In 2020, she moved to Plumas County and worked for the Feather River Resource Conservation District and began to understand the complexities of natural resource management and the implications of fire on the local landscapes. This compelled her to earn a master’s degree in environmental studies with a certificate in science communications and environmental education at the University of Idaho.

After personal experience with catastrophic fire, she is eager and ready to connect and assist communities as the postfire academic coordinator, to combine her passion for ecology and forestry management with outreach and education. 

Reidy is based at the UCCE Central Sierra office in Placerville and can be reached at kkreidy@ucanr.edu

Hartmann named UCCE community health and nutrition advisor

Janessa Hartmann joined UC ANR on Nov. 1 as the UCCE community health and nutrition advisor for Shasta, Trinity and Tehama counties to promote education and advance policy, systems and environmental changes that benefit local communities. 

Having lived and worked in Shasta County for over a decade, Hartmann is committed to improving the region’s health and wellness. She will be developing an integrated and equitable health and nutrition program, applying the latest research and data to address needs identified by the community – especially those of vulnerable populations such as older foster youth. 

In addition to focusing on positive youth development, Hartmann also aims to improve food security by expanding access to affordable and healthy food. 

“I hope to support community partners in health and nutrition across our region, and amplify existing effective programs,” she said. “I also look forward to working alongside the awesome CalFresh Healthy Living, University of California nutrition education program.”

Although Hartmann began her career in the environmental remediation field, she later worked on food sovereignty and security issues in central Mexico as a Peace Corps volunteer. In 2016, she became the CalFresh Healthy Living, UC program supervisor for Shasta, Trinity and Tehama counties. Subsequently, Hartmann joined Shasta County Public Health, where, during the height of the pandemic, she served as director of the COVID-19 Child Care, School and Higher Education Unit.

Jha joins UC ANR to address climate adaption

Prakash Kumar Jha joined UC ANR as an assistant project scientist on Nov. 1 and is responsible for developing decision support tools that help growers understand and minimize climate risks, specifically CalAgroClimate.

Prior to coming to California, he worked as a postdoctoral fellow for over five years in Italy, Spain and Colombia. Jha is eager to understand what California’s climate will look like in the next five to 10 years. Currently, he is working with climate prediction systems to determine future weather conditions, which growers can use to prepare for situations like low versus high chill hours, shortage of irrigation water and high temperature stress in plants.

Jha recognizes that areas currently used for agriculture might not be suitable for some crops a couple of years from now. For example, Jha is identifying which geographical areas growers should invest in while considering factors such as regulations limiting water use. His work will help growers consider the long-term implications of the decisions they make today.   

Before earning a Ph.D. in science management of climate change from the University of Venice Ca’ Foscari, Italy, he completed two master’s degrees – one in climate change adaptation from the University of the Sunshine Coast, Australia, and another in sociology from Tribhuvan University in Nepal. 

Originally from Nepal, Jha is excited about the diversity of crops the California offers. “I’m looking forward to expanding my knowledge, especially in tomatoes, cottons, almonds and pistachios,” he said.

Jha is based at the UC Merced-Sierra Nevada Research Institute and can be reached at prajha@ucanr.edu.

Khodadadi named UCCE plant pathology specialist

Fatemeh Khodadadi joined UC Riverside in October as an assistant professor of extension in the Department of Plant Pathology. She brings expertise in fungal and bacterial diseases of fruit and nut trees and an increasing interest in subtropical plant diseases caused by a variety of plant pathogens. 

Khodadadi’s research focuses on plant pathogens and disease management strategies for subtropical trees, especially citrus and avocado. She studies identification, characterization and development of molecular methods to detect fungal, bacterial and viral diseases affecting citrus and avocado, including but not limited to avocado branch canker and dieback caused by Botryosphaeria species, phytophthora root rot, sweet orange scab caused by Elsinöe australis, avocado sunblotch viroid and other problematic pathogens on citrus and avocado in California. She also studies the citrus and avocado defense responses to pathogens and the efficacy of fungicides and bactericides.

Before joining UC Cooperative Extension, she held postdoctoral fellowships at Cornell University and Virginia Tech conducting research in bacteriology, mycology, genomics, plant pathology and plant disease management focusing on Colletotrichum species (bitter rot of apple), Erwinia amylovora (fire blight), and Diplocarpon coronaria (apple leaf and fruit blotch). 

She identified, described and characterized for the first time a new Colletotrichum species that causes apple bitter rot and belongs to the C. gloeosporioides species complex. Her team named it C. noveboracense.

Khodadadi earned her M.S. and Ph.D. at Shahid Bahonar University of Kerman, Iran. For her M.S., she studied aflatoxin-producing fungi contaminating pistachio. In her Ph.D. research, partly conducted at UC Davis, she studied the interaction between walnut and bacterial blight disease caused by Xanthomonas arboricola pv. juglandis (Xaj). 

Khodadadi is based in the UC Riverside Department of Microbiology & Plant Pathology and can be reached at fatemeh.khodadadi@ucr.edu. She will be posting about her research at https://subtropicalplantpathology.com/category/blog-posts/.

Dompka to help spark economy in Del Norte, Humboldt and Trinity counties

Alec Dompka began with UC ANR on Oct. 20 as a rural communities economic development advisor. He will serve as technical support for economic development projects in Del Norte, Humboldt and Trinity counties.

Dompka said he aims to help local communities by working with government entities and private businesses to coordinate and facilitate beneficial projects.

“In this position, I hope to engage with people in the counties to tie them more closely with planning their economic development,” Dompka said. “I hope to show that economic development in rural communities can be locally led and directed, inclusive and effective.”

By applying technical knowledge and science-based expertise to these projects, Dompka said he also hopes to “generate research that pushes forward our understanding of what economic development looks like for rural communities.”

Born and raised in Raleigh, North Carolina, Dompka earned a bachelor’s degree from North Carolina State, double-majoring in political science and economics. He also holds an M.A. in agricultural and natural resources economics from NC State. 

Dompka is based at the Del Norte County UC Cooperative Extension office in Crescent City and can be reached at (707) 464-4711 or addompka@ucanr.edu. Follow him on Twitter @Alec_rural_dev.

Pearsons named IPM advisor for Monterey County

Kirsten Pearsons began working as a UC Cooperative Extension integrated pest management entomology advisor for Monterey, Santa Cruz and San Benito counties on Nov. 7. This is a new role for Pearsons, who joined UC ANR in March as a small farms advisor in San Luis Obispo County.

Pearsons focuses on insect-related concerns on the Central Coast, such as impatiens necrotic spot virus (INSV), a disease transmitted to lettuce by thrips, and identifying possible solutions. In collaboration with USDA scientists and her UC colleagues, Pearsons is researching the biology and ecology of the thrips populations that vector INSV to identify existing tools and new strategies that can help growers manage thrips and INSV.

Though her research focuses on lettuce and cole crops, Pearsons also supports berry growers and other specialty crop producers in the region with large-scale producers and agricultural pest control advisers as current clients. 

Pearsons earned a bachelor’s in environmental toxicology from UC Davis and a Ph.D. in entomology from Pennsylvania State University, studying how pest management strategies adopted in field crop systems affect non-target soil invertebrates.

During her undergraduate studies at UC Davis, Pearsons was curious to know what alternatives existed for broad-spectrum pesticides.

“Funny enough, I took my first entomology class just to get a basic idea of insect biology, because a lot of what I was learning in my toxicology courses had to do with insecticides,” she said. “The staff and the other students in the entomology department were so awesome that it didn’t take much for me to completely fall for the subject.”

Prior to UC ANR, Pearsons worked for the Rodale Institute, an organic research institute in Pennsylvania.

Pearsons is based out of the UCCE Monterey Bay County office and can be reached at kapearsons@ucanr.edu

Nguyen named UCCE food safety and organic production advisor

Cuong “Jimmy” Nguyen joined UC Cooperative Extension on Nov. 1 as an assistant food safety and organic production area advisor for Imperial and Riverside counties.

“Organic produce has a shorter shelf life and is more susceptible to outbreaks, recalls and foodborne illness due to the lack of chemical sanitizers and fungicides,” Nguyen said. “Therefore, my future research agenda will continue the focus on improving the quality and safety of organic produce commodities by developing alternatives to chemical fumigations/fungicides, as well as organic pest management without the use of chemical sanitizer or pesticide.”

While earning his Ph.D. in food science at UC Davis, Nguyen developed two novel sanitizing platforms for surface decontamination and liquid systems disinfection. The two systems involve the newly discovered synergistic disinfection effect between natural antimicrobials and UV-A light treatment or ultrasound treatment. 

“I am also interested in rapid detection methods using bacteriophage targeting foodborne microbes, and microscopic detection of bacterial microcolonies for early screening and prevention of foodborne outbreaks,” he said.

Nguyen earned a master’s degree at Tokyo University of Agriculture in Japan, where he studied sensory and food safety quality of meat, and a bachelor’s degree in agriculture at Nong Lam University in Vietnam, where he studied postharvest technologies for food and vegetable commodities. He is fluent in English, Japanese and Vietnamese.

Nguyen is based in Holtville and can be reached at (442) 265-7700 and
cgnguyen@ucanr.edu.

Wang named UCCE plant pathology advisor

Yu-Chen Wang joined UC Cooperative Extension Oct. 3 as a plant pathology advisor for Santa Cruz, Monterey and San Benito counties.

“Vegetable and berry are the major crops I work on currently,” said Wang, who will be working with a wide range of crops and different cropping systems on the Central Coast. “So far, I have been contacted by a wide range of growers – including (those who grow) lettuce, broccoli, pepper, celery, bean, apple, strawberry and blackberry – about their disease problems. I am passionate about providing insight to help the community on their disease problems.”

“The lettuce industry here is suffering from impatiens necrotic spot virus (INSV) vectored by Western flower thrip along with soilborne diseases,” she said. Lettuce growers in the Salinas Valley lost an estimated $50 million to $100 million last year and a lettuce supply shortage occurred. Working alongside fellow advisors, UC specialists and industry partners, Wang will be seeking long-term solutions for the industry. 

Prior to becoming a UCCE advisor, Wang worked at AVRDC-World Vegetable Center, for a vegetable seed company, and at UC Kearney Agricultural Research and Extension Center on research and development.

Wang, a native of Taipei, Taiwan, earned her B.S. and M.S. in horticultural and crop science at National Taiwan University. She earned a second M.S. in plant protection from California Polytechnic State University, San Luis Obispo.

“The idea of farmers feeding the world and awareness of crop loss by pests motivated me to pursue a career in agriculture and plant protection,” she said. “During my M.S. at Cal Poly, I worked closely with the California strawberry growers on industry-oriented research. I look forward to extending my study to vegetable and berry crops and serving the farming community.”   

Wang is based in Watsonville and can be reached at yckwang@ucanr.edu and (831) 201-9689.

Hooper named UCCE urban community resiliency advisor

Ashley Hooper joined UC ANR on Sept. 1 as the UC Cooperative Extension urban community resiliency advisor in Los Angeles County, a brand-new position. In her role, Hooper is tasked with working with communities who have historically been disadvantaged due to inequitable systems and/or policies.

In collaboration with the community, Hooper will lead efforts focused on building resilience and adaptive capacity. This could look like increasing the community’s access to capital, green space, transportation, nutritious food or education.

She already has leveraged data, collected by different organizations, to conduct a content analysis of needs assessments across dimensions of community resilience, such as access to parks and healthcare. Then, as next steps, she will prioritize interviews and field observations.

During her master’s program, Hooper worked as a research assistant for the Bureau of Business and Economic Research, where she led interviews with community members facing or trying to counter various inequities like limited access to broadband, housing and health care. For her Ph.D. dissertation, she focused on identifying barriers to and opportunities for resilient food systems in Los Angeles County.

After attending the California Economic Summit in October, Hooper shared her excitement for the prospect of using the arts in building community resilience.

“I went to a creative-economy working group session, and I was reminded of how much the arts and cultural community has to offer in the process of building adaptive capacity in communities,” she said.

Hooper earned a Ph.D. in urban and environmental planning and policy from UC Irvine. She earned a bachelor’s degree in psychology and a master’s degree in water resources with a concentration in policy and management from the University of New Mexico.

Hooper is based out of the UCCE office in Los Angeles County and can be reached at asmhoope@ucanr.edu.

Solins joins UC ANR as new environmental horticulture advisor

Joanna Solins joined UC ANR on Oct. 3 as a UC Cooperative Extension environmental horticulture advisor for Sacramento, Solano and Yolo counties.

Solins will focus on research and outreach related to urban plants, landscaping and climate change, while building relationships with county and municipal governments, nonprofits, landscape and tree care professionals, nursery growers and utilities, among others. She also will support the UC Master Gardener coordinators in her assigned counties, collaborating to extend knowledge and resources to community members. 

“My core goals are to improve the climate suitability and ecological performance of urban landscaping and promote the equitable distribution of benefits from urban plants,” Solins said.

After attaining a bachelor’s degree in environmental studies at Vassar College, Solins began her career leading outreach education programs for the New England Aquarium and writing for educational publishers. She also worked in communications at the Coral Reef Alliance in San Francisco before starting graduate school at UC Davis, which culminated in a master’s in geography and Ph.D. in ecology.

Solins’ research at UC Davis combined field studies and geographic information system analysis to investigate plant communities, tree canopy and soils along urban creeks in the Sacramento area. She also carried out postdoctoral research on green stormwater infrastructure, urban forest composition, and the water demand of urban vegetation across California, and contributed to projects examining residential landscaping and urban heat in Sacramento.

Mar named UCCE organic materials management advisor

Stephanie Mar joined UC Cooperative Extension on Oct. 3 as the assistant organic materials management advisor serving Los Angeles, Orange and San Diego counties. Mar is responsible for investigating ways to divert organic wastes from landfills to alternative end markets, such as circular food economies, composting and wastewater reclamation.

“To me, waste doesn’t have an end life, just a next life,” said Mar. “A lot of people don’t know what happens to their waste after the garbage truck comes or they flush a toilet, so a part of my job is to understand what we are wasting and what happens to it.”

Mar attended the University of North Carolina at Chapel Hill where she earned a master’s degree in public health focused on environmental science and engineering, and a master’s degree in city and regional planning focused on land use and environmental planning. She also has a bachelor’s degree in public health from UC Berkeley. 

Much of Mar’s professional experience, like her time working for the City of Berkeley, is centered on community outreach and policy development, two strengths that she believes will serve her well in this new role. 

Previously, Mar worked as a public health analyst for UC San Francisco and as a social research analyst with the North Carolina Department of Health and Human Services too. Both of which strengthened her understanding of policy and program development, implementation, and monitoring and evaluation.

“Research gives us a lot of information, but then there’s a need for translation from what we know to what it actually means,” she said. “There are a lot of people doing different things [to manage their waste], so there’s a need for coordination and dispersal of information.”

Mar’s background in policy development is something she’ll rely on to operationalize the research being done by herself and her colleagues. 

Behavioral change is one of Mar’s anticipated challenges in this role. Even if research and policy efforts yield successful results, encouraging the community to adapt can be an uphill battle.

“Sorting trash, for example, is more of a mental burden than a physical one,” she explained. “We know what the research says and what we need to do, it’s just about developing the market to make it happen.” 

Mar is based out of Irvine at the South Coast Research and Extension Center and can be reached at samar@ucanr.edu

Conversion to Organics Could Increase Food Prices, Shrink Farm Profits

By Peter Hecht, California Farm Bureau

A European Union policy goal to exponentially increase organic farming to 30% of all agricultural production by 2030 is expected to be considered by Gov. Gavin Newsom for next year’s budget. However, a new economic analysis says such a plan would dramatically increase the price of food for many consumers and jeopardize the solvency of organic farms.

California currently has an estimated 7.35 million acres of irrigated cropland, of which 460,000 acres—or 6%—is certified as organic and not all of that is farmed in any given year.

A preliminary analysis by ERA Economics, a Davis-based consultancy specializing in the economics of agriculture and water resources in California, focused on the potential challenges of applying the EU standards to one California crop: tomatoes. The state produces 95% of America’s processing tomatoes and the total annual tomato crop is valued at $1.2 billion.

Only 5% of California’s 228,000 processing tomato acreage is currently needed to meet consumer demand for organic. The study found that reaching 30% organic production by 2030 would cause substantial disruptions to the market. The farmgate price of conventional tomatoes was estimated to rise by more than 11%. And, importantly, the price for organic tomatoes was estimated to fall by 28% at the farmgate level—potentially putting the market price below the cost of production.

That could mean organic farmers would be forced to cease production, sell, or farm something else—a result that could potentially crash the organic market and ultimately drive-up consumer prices. Mandating an increase in organic acreage without a clear connection to consumer demand could result in market disruptions that would hurt farmers, farm employees and consumers alike, the study noted.

Any initial organic price drop would mostly benefit wealthier consumers who purchase organically grown products, with lower-income customers paying more for traditionally grown products. All tomato farmers, organic or not, could see reduced profits, according to the analysis.

“Farming works when we are able to grow what the consumer actually wants and not what government mandates. California consumers are already struggling to afford higher prices for food than other states because of government mandates and these types of proposals just make things worse,” said Jamie Johansson, president of the California Farm Bureau. “When the government increases the price of food, it acts like a regressive tax, hurting lower- and middle-income families the hardest. At the end of the day, the government needs to let organic markets grow organically.”

The study was funded by Californians for Smart Pesticide Policy, a coalition of farmers and businesses the rely on farmers, focused on educating policymakers on the benefits of modern scientific agricultural tools. It was undertaken on behalf of the California Bountiful Foundation, the 501(c)(3) science and research arm of the California Farm Bureau. The full report may be found at https://www.californiabountifulfoundation.com/research/.

A recently released report (https://www.fb.org/newsroom/farm-bureau-survey-shows-thanksgiving-dinner-cost-up-20) by the American Farm Bureau Federation shows that the average cost of a family’s Thanksgiving dinner—now $64.05—is up 20% from 2021 and nearly 36% from 2020.

The findings by ERA Economics include the following:

• To increase organic acreage for processing tomatoes from an average of 4% to 30% would represent a five- to six-fold increase in current acreage. Tomato growers and processors interviewed for the analysis confirmed industry data regarding consumers’ finite desire to purchase organic tomato products.

• Tomato growers may specialize in organic, non-organic or both, depending on market demands and conditions. By mandating a specific growing method, it could greatly impact the ability of farmers to keep their operation sustainable, both financially and as they encounter other challenges, such as climate change and pests and disease.

• Both conventional and organic farmers of processing tomatoes face risks of economic losses. Conventional growers, with likely reduced acreage, could see a 17% potential downside cost from expected earnings.

• Organic production presents greater risk of crop failure, higher production costs and lower crop yields. As a result, organic farmers are likely to see less stability. They face a potential downside cost of 36% of anticipated net returns, making it potentially unprofitable to grow organic processing tomatoes.

New Interactive Web Tools Help Growers Cope With Climate Change

By Pam Kan-Rice, UCANR

UCCE, USDA California Climate Hub launch CalAgroClimate decision-support tool

Climate and weather variability pose increasing risks to farmers. As world leaders gather in Egypt at COP27 to address the climate crisis, University of California Cooperative Extension and the USDA California Climate Hub are launching new web-based tools to provide farmers with locally relevant and crop-specific information to make production decisions that reduce risk.

“Integrating historical weather data and forecast information with meaningful agricultural decision support information holds the potential to reduce a crop’s vulnerability to such risks,” said Tapan Pathak, UC Cooperative Extension climate adaptation specialist at UC Merced.

“To provide easy access to high-resolution data in the form of agroclimate tools and information, and to enhance agricultural resilience to climate and weather-related risks, we are launching CalAgroClimate,” Pathak said.

Pathak is collaborating on building the decision support tool with partners from the U.S. Department of Agriculture, California Climate Hub, UC Cooperative Extension and UC Agriculture and Natural Resources’ Informatics and Geographic Information Systems or IGIS.

“CalAgroClimate has been designed to support climate-enabled decision making for those working in the California specialty crop industry,” said Steven Ostoja, director of USDA California Climate Hub. “The USDA California Climate Hub is a proud collaborator on this important initiative to ensure the state’s agricultural industry can continue to thrive in a future of climate change.”

Shane Feirer and Robert Johnson of UC ANR IGIS designed the interactive tools on the website and Lauren Parker of the USDA California Climate Hub contributed to content organization.An advisory panel composed of colleagues from UCCE and the Natural Resources Conservation Service ensures CalAgroClimate tools are relevant to stakeholder needs.

“CalAgroClimate is an amazing new tool that puts comprehensive past and forecast weather data at any grower’s disposal,” said Mark Battany, UC Cooperative Extension water management and biometeorology advisor for San Luis Obispo and Santa Barbara counties.

“California’s high-value crops are subject to a myriad of weather-related risk factors; this tool will allow growers to better address both near-term and long-term risks, and in the end grow more profitably,” said Battany, who is a member of the CalAgroClimate advisory panel.

Growers and crop consultants can use CalAgroClimate’s crop and location-specific tools and resources to help make on-farm decisions, such as preparing for frost or untimely rain and taking advantage of expected favorable conditions.

CalAgroClimate currently includes heat advisory, frost advisory, crop phenology and pest advisory tools.

Heat advisory tool: Extreme heat poses a danger for people, animals and crops. With this tool, users can select location and temperature threshold (e.g. 90 F, 95 F 100 F) based on their crop-specific heat tolerance level and the tool will provide a customized map of heat risk for the next seven days for that location, including the number of consecutive days with temperature above that threshold. Users also can assess overall heat risks across the state for a selected temperature threshold as well. With an early warning about hot temperatures, growers can take steps to reduce risks associated with extreme heat such as providing shade, changing farmworkers’ schedules and applying additional irrigation.

Frost advisory tool: Frost risk is a serious issue for many specialty crops across California. Similar to the heat advisory tool, this tool provides a customized map of frost advisory for the next seven days for a user’s location, and a forecast of consecutive days with temperature falling below the selected temperature thresholds (e.g. 35 F, 32 F, 28 F). Early warning about cold temperatures can provide growers some time to protect their crops from frost damage.

Crop phenology tool: The scientists have developed a-crop specific and location-specific crop phenology tool to help users keep track of growing degree days accumulations and estimate critical growth stages. CalAgroClimate uses a high-resolution PRISM dataset to provide near real-time crop phenology information to users. This tool will inform growers about how their crop development compares to previous years, which can be helpful in planning activities specific to critical growth stages.

Pest advisory tool: Similar to crop growth, development of certain pests and diseases is controlled by temperature and heat unit accumulations. With the pest advisory tool, growers can keep track of estimated pest generations during the growing season to make pest management decisions.

“We are launching the website with this initial set of tools while working on adding more crop-specific information and several new tools in the near future,” Pathak said. “We look forward to getting feedback from growers who use CalAgroClimate to make it even more useful.”

Farmers Fear Zero-Emission Trucking Proposal Could Strand Farm Products

By Caleb Hampton, California Farm Bureau

The California Air Resources Board is considering a proposed regulation to phase out big rigs and other trucks with internal combustion engines and replace them with zero-emission vehicles.

The proposed Advanced Clean Fleets regulation would include vehicles that transport agricultural commodities.

It would follow a 2020 executive order by Gov. Gavin Newsom banning the sale of new gas-powered cars by 2030, and apply to medium-duty and heavy-duty internal combustion vehicles. The proposal would force some federal agencies and trucking companies to begin converting their fleets to zero-emission vehicles in 2024 and prohibit the sale of all new fossil-fueled trucks by 2040.

Replacing these trucks and large delivery vehicles with zero-emission vehicles would augment California’s push to reduce air pollution and carbon emissions. While diesel-powered trucks represent a small fraction of the 30 million vehicles registered in the state, they produce about 70% of its smog-forming gases and 80% of carcinogenic diesel pollutants, according to the air resources board.

During a public hearing on Oct. 27, environmental advocates and industry groups clashed over the proposed rule. Environmentalists pushed for tighter rules and faster deadlines. Trucking industry leaders raised concerns about costs and the readiness of the electrical grid, vehicle technology and charging infrastructure for a statewide transition to zero-emission trucks within the proposed timeframe.

California farmers who rely on trucking companies for the timely transport of fresh commodities have also voiced concerns.

“Their concept is great, but the application is going to be hard,” said Keith Nilmeier, who farms 220 acres of oranges, peaches, apricots and grapes in Fresno County, and runs a trucking business with a fleet of 18 trucks. “They’re trying to drop it way too fast.”

Farming groups have pointed to a lack of rural charging stations and the limited range of zero-emission trucks, which they fear could slow or disrupt agricultural transport.

“Livestock, fruits and vegetables need to be transported in a timely manner to ensure food and animal safety,” Katie Little, policy advocate for the California Farm Bureau, said at the air resources board hearing. “The time required to charge these vehicles, in addition to the time needed to travel to these charging facilities, could jeopardize food security and availability.”

In typical tomato haul, for instance, a truck might travel over 800 miles in a 24-hour period. If the zero-emission vehicle’s range isn’t far enough, the charging infrastructure is not in place, or the electrical grid can’t handle the amount of big rig truck batteries that need to be charged, that could leave vehicles stranded in hot temperatures with thousands of pounds of fresh tomatoes.

State officials are pledging to invest $10 billion over several years to expand charging infrastructure and transition to zero-emission vehicles. But there currently are fewer than 2,000 zero-emission medium-duty and heavy-duty vehicles on California roads.

Joe Antonini, owner of Stockton-based Antonini Freight Express, which trucks tomatoes, almonds, walnuts and olives, said, “The infrastructure needs to be built prior to putting in place mandates.”

A coalition of commercial, transportation and agricultural organizations, including the California Farm Bureau, raised concerns about the proposed rule.

“We are extremely concerned that the proposed ACF rule will be unworkable in the real world and could result in compromising the delivery of essential goods and services to Californians,” the groups said in a letter to the air resources board.

Even if the basic infrastructure were in place, trucking company owners say the rule would impose significant hurdles.

Due to the weight of an electric truck battery, trucks could have their load capacity reduced by around 8,000 pounds, forcing companies to operate more vehicles in order to move the same tonnage. And with some of those vehicles sidelined while they charge, Antonini said his company, which has 240 trucks, may need as many as 50% more vehicles to move its freight.

With the sector already facing a driver shortage, the need for trucking companies to scale up their fleets could cause disruptions that impact farmers. “There are so many challenges on the ag side,” Antonini said. “This whole legislation will, in my opinion, have a very negative impact on California agriculture.”

Other farmers and trucking company owners raised questions about the cost of zero-emission vehicles, how long it might take to charge them and how many trucks could charge simultaneously at a single charging station.

“It’s terrifying for me to even think about,” said Tom Barcellos, owner of Barcellos Farms, a Tipton-based dairy farm and trucking company.

The upfront cost of an electric truck exceeds that of a conventional one, though the state’s air board staff project the cost of a zero-emission truck will go down as more models enter the market. They estimate that by 2035 it will be cheaper to buy and operate an electric semi-truck than a conventional one.

Nonetheless, farmers and trucking company owners expressed anxiety over the proposed timeline for transitioning the state’s fleets from diesel to electric. With diesel trucks, Barcellos said, “we can turn the key and go whenever we need to.”

The air resources board is set to hold a second hearing and a vote on the proposed rule in the spring. After a regulation is finalized, it would be subject to a public comment period.
