De Guzman named first UCCE specialist at UCLA 

Edith de Guzman joined UC ANR Sept. 1 as a UC Cooperative Extension water equity and adaptation policy specialist. She is the first UCCE specialist to be based at UCLA.  

Her work investigates best practices for the sustainable transformation of the Los Angeles region and beyond, and has included research, demonstration projects, public policy and planning in the areas of water management, climate adaptation, heat mitigation and urban forestry. She tackles these topics through the lenses of urban planning, public health, behavioral sciences, biophysical sciences and public policy. 

She co-founded and directs the Los Angeles Urban Cooling Collaborative, a multisectoral partnership working to alleviate the public health risks of extreme heat. Their research has found that one in four lives currently lost to extreme heat could be saved if L.A.'s land cover had more trees and its built surfaces were more reflective, particularly where low-income communities and communities of color live and work.

From 2014 to 2020, de Guzman served as director of research at the Los Angeles-based organization TreePeople. Her projects at the nonprofit included the City of Los Angeles Stormwater Capture Master Plan; facilitating the creation of a Greening Plan with the Inglewood and Lennox communities; bringing to fruition multiple urban water-management demonstration projects; and leading an extensive study tour of Australia's response to its historic Millennium Drought and gleaning lessons for California. She also produced the first interactive, high-resolution public map and spatial analysis of Los Angeles County's urban forest. 

Having completed all of her studies at UCLA, de Guzman holds a Ph.D. in environment and sustainability, a master's degree in urban planning and a bachelor's degree in history and art history.

Van Cleave-Hunt named UCCE nutrition, health and food security advisor 

Veronica Van Cleave-Hunt began a new position within UC ANR on July 5 as the UC Cooperative Extension community nutrition, health and food security advisor serving Butte, Colusa, Glenn, Sutter and Yuba counties.

Before beginning her current position, Van Cleave-Hunt served for four years as a community education specialist for the CalFresh Healthy Living, UC program before becoming the program supervisor serving the same counties.

“Luckily, I already have my finger on the pulse of the community in these five counties just through my experience with CalFresh. I've been able to build rapport and connections with a lot of community partners and stakeholders,” said Van Cleave-Hunt.

As an advisor, Van Cleave-Hunt will focus on nutrition, education and healthy living efforts for people who are at a disadvantage, for example, those living in food deserts or experiencing food insecurity, a term used to describe the societal and environmental barriers to access and manage food. 

“Food security is about environment and access, but also skills related to food,” Van Cleave-Hunt said. “For instance, budgeting, even things like gardening, cooking and knowing how to prepare food so that you don't always have to buy ready-made food, or how to store things properly so that they last as long as possible.” 

According to Van Cleave-Hunt, food security includes skills that will help you get the most out of the food that you have.

Currently, Van Cleave-Hunt is compiling secondary data to conduct a needs assessment. In addition to engaging stakeholders such as resident service coordinators at low-income housing units or community organizations, she is also working with the State Council on Developmental Disabilities to develop healthy living trainings and curricula that will benefit communities in her counties.

Van Cleave-Hunt said that her time with UC Cooperative Extension has been a “full-circle journey” since she studied human behavior and health in school. She started her undergraduate career at Santa Rosa Junior College before transferring to California State University, Chico where she earned a bachelor's in nutrition and a master's degree in nutrition education.

Chelsey Slattery, former UCCE area nutrition, family, and consumer sciences advisor for Butte County, recruited Van Cleave-Hunt right out of college to be a UC Cooperative Extension community education specialist. Today, Van Cleave-Hunt holds the position that Slattery once did. 

Van Cleave-Hunt can be reached at vvancleavehunt@ucanr.edu and is based in Oroville.

Wayne joins UCCE as food systems advisor 

Laurie Wayne joined UC Cooperative Extension on July 5 in Modoc County as a nutrition and food systems advisor for Modoc, Lassen and Siskiyou counties. Wayne will work with community members on healthy lifestyles, nutrition, food access and security, local food production, preservation and availability. 

Wayne brings years of high-desert food systems experience to her role: she owned and operated Locavore Farms in Fort Bidwell, helped found the Surprise Valley Saturday Market and Modoc Harvest, and was on the team that started the Modoc Harvest Food Hub. She also has worked supporting healthy communities for Oregon State University Extension in Klamath Falls, and at the High Desert Food and Farm Alliance in Bend, Oregon.

She earned a master's degree in TESOL (to teach English as a second language) from Portland State University and worked in school and community gardens with immigrants and refugees as part of her research project. She earned a bachelor's degree in Italian literature from UC Santa Cruz.

This job feels like the culmination of the farming, studying, supporting farmers and working in food systems she has done in the past 15 years, Wayne said.

“I'm especially interested in working on expanding access to affordable, healthy, local food year-round, including extending and preserving the harvest,” Wayne said. Her goal is to help everyone feel empowered to make healthy food choices, and she's learning what resources producers need to improve processing, transportation and production strategies, and overcome barriers that are unique to the region. 

To better understand both the food systems needs and the abundant food assets of northeastern California, she will be meeting with community members; state, local and regional nonprofits; schools and other organizations in the next few months. They will discuss ways to strengthen community food system resilience.

“It's all about healthy community members who can eat good local food without breaking the bank, and producers who can make a living feeding them,” Wayne said.

Based in Alturas, Wayne can be reached at lwayne@ucanr.edu and (530) 233-6400.

Hyland named UCCE environmental health sciences specialist 

Carly Hyland joined UC ANR in July as a UC assistant Cooperative Extension environmental health sciences specialist and assistant professor in the UC Berkeley School of Public Health.

She recently finished a mixed-methods project at Boise State University examining pesticide exposure and perceptions of the risks of pesticides among Latino men and women farmworkers in Idaho. In California, she is pursuing projects examining interventions to protect farmworkers from pesticides, extreme heat and wildfire smoke in collaboration with community partners.

“There are so many reasons I wanted to come back to Berkeley, and I think one of the biggest motivating factors for me was the collaborative environment focused not just on conducting innovative research, but also translating those findings into solutions to improve community health,” Hyland said. “Farmworkers are increasingly experiencing the health impacts of climate change on a daily basis, and this position will provide me with the resources and collaborations necessary to identify strategies to address these urgent issues.”

Hyland earned her Ph.D. in environmental health sciences and master's degree in global health and the environment, both from UC Berkeley, and bachelor's degree in environmental science from Carthage College in Wisconsin.

Hyland is based at UC Berkeley and can be reached at chyland@berkeley.edu and on X (formerly Twitter) @c_hyland1.

Smith-Helman joins Climate Smart Agriculture Program 

Bailey Smith-Helman joined UCCE Santa Cruz County on July 3 as a community education specialist with the UC ANR Climate Smart Agriculture Program.

Smith-Helman, who relocated from Washington, D.C., is excited to get back in the field and support Santa Cruz County growers with climate-smart agriculture practices and California Department of Food and Agriculture financial incentive programs.

CDFA programs provide financial incentives to eligible farmers and ranchers implementing new practices that maximize water efficiency, build soil health, and improve manure management. She is ready to assist interested growers with grant applications, project planning and implementation.

After graduating from Northwestern University with a bachelor's degree in political science and environmental policy, Smith-Helman moved to Paraguay to serve as an agriculture volunteer with the Peace Corps. In Paraguay, she worked closely with agricultural educators and local producers to develop education plans and lessons to engage high school students in agricultural coursework.

After returning to the U.S., Smith-Helman worked for USDA Supplemental Nutrition Assistance Program, where she gained experience in agriculture policy analysis and program management.

Sayre named UCCE agriculture and resource economics specialist 

James “Jay” Sayre joined UC Cooperative Extension and the UC Davis Department of Agriculture and Resource Economics as a CE Specialist on July 1. 

His role focuses on the economics of food supply chains across the state of California. Sayre aims to study policies to promote greater competition in food supply chains to benefit smaller-scale producers, understand the role of international trade in agriculture and its effects on Californian consumers, and assess how supply chains can best respond to a changing climate. 

Sayre is excited about combining economic theory and modeling approaches with understanding the needs of stakeholders in California to benefit food supply chains within California.

Sayre earned a doctorate in Agricultural and Resource Economics at UC Berkeley. His dissertation research spanned several disciplines, with chapters seeking to understand how agricultural supply chains lead regions to specialize in certain crops, the consequences of phytosanitary and other non-tariff barriers to trade, as well as developing methodology to accurately assess crop yields across large regions using satellite imagery and other sources of publicly available data. He earned a bachelor's degree in economics and mathematics from the University of Minnesota-Twin Cities. 

The Colorado native is looking forward to addressing a variety of issues relevant to California stakeholders. An ongoing project looks to develop fine-scale projections of future agricultural productivity for most of the major crops California produces, including crops that have historically not had such measures available, like perennials such as almonds, avocados and other fruits.

He hopes such information will be relevant not only for growers seeking to understand whether their land will be relatively more suitable in the future for different crops, but also agricultural intermediaries and policy makers looking to understand where production of certain crops may shift in the future.

Before joining Cooperative Extension and UC Davis, Sayre worked in Mexico, seeking to better understand the cross-border nature of supply chains that operate in both California and Mexico. He is proficient in Spanish and aims to increase the accessibility of extension to Spanish speakers. 

Sayre is based out of the Department of Agriculture and Resource Economics at UC Davis and can be reached at jsayre@ucdavis.edu.  

Valliere joins UCCE as weed and restoration ecology specialist 

Justin Valliere joined UC ANR on July 1 as an assistant professor of Cooperative Extension in invasive weed and restoration ecology at UC Davis. 

Valliere's research aims to evaluate how human-caused environmental change and invasive plant species impact native ecosystems, and how we can reverse this degradation through ecological restoration. The overarching goal of his research and outreach is to develop real-world solutions for land management in the face of global change.

“CE already is such an effective system for supporting agriculture, but it's also an important model for natural resource management and restoration,” Valliere told Trina Kleist, writer for the UC Davis Department of Plant Sciences. “There is a real need for help advising folks throughout the state about managing and restoring natural lands, and I'm excited to help bolster that.”

Prior to joining UC Davis, Valliere was an assistant professor of biology at CSU Dominguez Hills, a research fellow at the University of Western Australia, and a postdoctoral fellow at the La Kretz Center for California Conservation Science at UCLA.

Valliere earned his Ph.D. in plant biology from UC Riverside, and a bachelor's degree in biology from Green Mountain College in Poultney, Vermont. 

Valliere is based in the Department of Plant Sciences at UC Davis and can be reached at jmvalliere@ucdavis.edu. 

Hill named UCCE specialist in diversity and equity economics 

Alexandra “Ali” Estvan Hill joined UC ANR and UC Berkeley's Department of Agricultural and Resources Economics on July 1 as an assistant professor of Cooperative Extension specializing in the economics of diversity and equity. 

From 2019 until she joined UC, Hill worked as an assistant professor of agricultural economics at Colorado State University. Her research centers around the U.S. agricultural workforce and seeks to demonstrate how a variety of factors impact worker well-being, quantified in terms of income or health impacts – and to make a business case for employers, in terms of implications for production or profits, to institute policies and practices that promote worker well-being.

Hired farmworkers contribute greatly to the racial, ethnic, cultural and socioeconomic diversity of U.S. agriculture; however, they are frequently not treated equitably and face a multitude of economic, physical, legal and emotional hardships in their personal and professional lives. Hill's research seeks to begin dismantling these inequities by finding avenues through which employers can increase worker well-being while maintaining or increasing profits. 

Hill brings extensive experience working with individual agricultural businesses to accomplish these objectives through enhancing firm data collection and analysis to provide an array of effective, efficient and actionable insights. 

She is building an extension program centered around advancing diversity, equity, inclusion and belonging in the agri-food system by enhancing the well-being of agricultural employees and other disadvantaged members of rural and urban agricultural communities. 

She earned her Ph.D. in agricultural and resource economics from UC Davis and master's degree in agricultural and applied economics and bachelor's degree in agricultural and consumer economics from University of Illinois, Urbana-Champaign.

Hill is based at UC Berkeley and can be reached at alihill@berkeley.edu and on LinkedIn www.linkedin.com/in/alexandra-estvan-hill.
