Tribal Engagement at the Hopland Research and Extension Center

 

The Hopland Research and Extension Center is situated on the traditional, ancestral and unceded lands of the Shóqowa and Hopland People, whose historical and spiritual relationship with these lands continues to this day and beyond (for more on the Land and people history of the site, see this story map). It was, and continues to be, difficult for Indigenous people to thrive in the Shanél Valley after they were forced off the fertile land and had to resettle on relatively small upland parcels and away from freshwater sources. UC ANR staff and academics at the Hopland Research and Extension Center are working to build relationships with the Hopland Band of Pomo Indians who live and work next door at the Hopland and Nacomis Rancherias.

Hopland REC Director John Bailey is committed to building relationships with the intention of enabling maximum benefits for local tribal communities. Tribal Chairperson Sonny Elliot and the Council have been helping us find ways to collaborate after a long history of distrust and despite the University's founding using the sales of expropriated lands (Land-Grant College Act, 1862) and our continued occupation of California Indian territories. Bailey is working with local tribes to define a newly funded Academic Advisor position to build relationships, advance UC policy around working with Tribes, and restore good fire to the landscape with the help of cultural practitioners. 

We have secured funding to hire a Native college student to help revitalize ecocultural wetlands in Hopland this summer. The intern will spend time talking with Indigenous people living within the oak woodland landscape or North Coast California and develop a plan for stewarding ecoculturally important sites at the Hopland Research and Extension Center with the Hopland Band of Pomo Indians and local experts in traditional ecological knowledge. This internship offers an opportunity for a Native American college student or two to learn about wetland systems and traditional ecological knowledge; and share their experience with other tribal community members.

Hunting opportunities for Tribal youth and their families and plant collection sites for basket materials are available. The hope is that more cultural ceremonies can take place where generations of Pomo people spent time near the waterways that span Hopland REC. Finally, together we are exploring ways to modify access of existing roads at Hopland REC to allow for potential emergency evacuation for Rancheria residents.

More to come, we hope.

Agricultural research and education center moving to new site in Ventura County

UC Hansen Research and Extension Center to expand capacity at Camarillo location

The University of California Hansen Agricultural Research and Extension Center – the site of popular school field trips, 4-H programs, a UC Master Gardener demonstration garden, and numerous research trials on crops and landscape plants – is moving to a new location on the west side of Camarillo. The center was established through an endowment bequeathed to the UC by Saticoy farmer Thelma Hansen, who sought to support university research and extension activities benefiting Ventura County.

For the past 25 years, Hansen REC has been located on the historic Faulkner Farm in Santa Paula. At 27 acres, Hansen REC was the smallest of the nine RECs across the state operated by UC Agriculture and Natural Resources; in 2019, UC ANR leadership decided a larger property was needed to expand the center's capacity. The Faulkner Farm was sold in March 2021, but a portion was leased back to the UC to sustain its programs until a new location was identified.

In December 2022, the UC acquired a 114-acre farm property in Camarillo to serve as Hansen REC's new home. Moving structures and equipment from Faulkner Farm will take place over the next six months. Public programs at the new location are on hold until seismic retrofitting and other building upgrades are completed. A new research and educational facility also will be built, with an estimated opening date in 2027 or 2028.

“Our planning committee looked for a site on the Oxnard Plain that is representative of the coastal agriculture environment and conducive to research on Ventura County's high-value crops, such as strawberries,” said Annemiek Schilder, Hansen REC director. “We also sought a location with diverse soil types, access to sufficient irrigation water, and a low risk of flooding – and we're pleased that this Camarillo property meets most of our search criteria.”

Of the approximately 104 cultivable acres, 28 are certified organic, which will allow researchers to study organic as well as conventional crop production methods, Schilder noted. She said another bonus of the new location is its proximity to California State University, Channel Islands and the Rodale Institute California Organic Center, which are both potential partners for future research and a student organic farm on site.

Initial plans for the new Hansen REC facility include offices, conference rooms, laboratories, greenhouses, a demonstration kitchen, and indoor and outdoor education areas. The center will aim to be water-efficient and energy-neutral, relying on solar panels for much of its energy usage. The UC Cooperative Extension Office in Ventura is also slated to move to the new facility.

“We fully expect Hansen REC to become a vibrant research and education hub that provides science-based solutions and is responsive to the needs of agricultural, rural and urban communities and the environment in Ventura County,” said Glenda Humiston, UC vice president for agriculture and natural resources. “We're excited to expand current programming while bringing in new educational opportunities, such as the UC Master Food Preserver and Master Beekeeper programs.”

Desert Research and Extension Center hosts international agriculture student interns

Caring for feedlot cattle, examining onion irrigation practices, and teaching preschoolers about agriculture are not part of the typical college curriculum. But for Desert Research and Extension Center's five college student interns, these activities are what fill their days.

Located on 255 acres of Southern California desert, DREC focuses on advancing irrigated desert agriculture, livestock and feedlot management, and pest management. It is also home to the Farm Smart agricultural education program, reaching approximately 7,800 participants annually.

In February, DREC welcomed the college student interns - creative thinkers working at the intersection of experimental research and agriculture education. During the internship, the students are working on-site under the mentorship of academics and staff members on applied projects. After years of COVID restrictions, the center is excited to welcome the students in person for hands-on engagement with the research and the public.

"Hosting students at DREC helps us to fulfill our mission while training the next generation of professionals," says Jairo Diaz, Director of DREC. "I am particularly motivated to provide experiential learning activities to underrepresented groups in agriculture and STEM careers."

Read on to learn about each of these budding agronomists.

Dianely Alba

Dianely Alba is majoring in agronomy at the Universidad Autonoma de Baja California, Mexico (This university is about 20 miles south of DREC). She is working under the mentorship of Jairo Diaz-Ramirez on a project focused on improving irrigation and nutrient management practices in onion production in Imperial County.

Melina Munoz

Melina Munoz is a student at Imperial Valley College studying elementary education. She is an intern for DREC's Farm to Preschool Festival. Munoz is in charge of developing and translating activities, planning and implementing the festival, and data entry for participant registration and evaluation information.

Lester Nolasco

Lester Nolasco grew up on a farm in Honduras, so he has been involved with animals and agriculture from a young age. He is working under the mentorship of Pedro Carvalho, the Feedlot Management Specialist. Nolasco is currently working on feedlot cattle management and beef cattle nutrition. 

“Although my passion is cattle, when you work with these animals, you indirectly learn about agriculture and crops in general because that is also an important part of cattle nutrition,”says Nolasco. Alongside the other feedlot management interns, Nolasco feeds animals, cleans pens, mixes feed, weighs cattle, and does lab work. “It is such a nice experience for me because I had only worked with dairy cattle in the past and this internship is teaching me a lot. I would like to learn as much as I can about beef cattle nutrition. Hopefully, in the future, I will be a professor and share the knowledge I have learned with other professionals back in my country.”

Heitor Otávio Martins de Oliveira

Heitor Otávio Martins de Oliveira has worked with animals throughout his life, starting with his parents' farm. He attended veterinary school, where he continued to learn about agriculture. At DREC, Otávio Martins de Oliveira is working on beef cattle nutrition management. In addition to daily maintenance tasks, he weighs the cattle monthly and provides any necessary treatments. 

“I would like to get as much knowledge as I can about nutrition in the USA and then return to my home country of Brazil to work there,” says Otávio Martins de Oliveira. “Maybe I will get a master's degree related to reproduction in cattle.”

Willi Meireles

Willi Meireles was introduced to Carvalho by his professor in Brazil. He is working on evaluating the use of feed additives to increase the performance of feedlot cattle.

“My grandparents own a farm where beef cattle are raised, so since I was a child, I have worked with animals and always liked animal science,” reflects Meireles. “I intend to specialize in ruminant nutrition and, after working hard, be able to have my own beef cattle.”

New wave of California Naturalists emerge from course at Hopland REC

Thirty-eight young, budding naturalists sit in a meadow while journaling and sketching their observations of the wildflowers and birds around them. They have come from various educational backgrounds to gather at the University of California Agriculture and Natural Resources' Hopland Research and Extension Center (REC) to learn about local natural ecosystems through a California Naturalist course.

Although they vary in expertise, these students share a common motivation: immerse themselves in the natural world and eventually teach others about its importance.

“The class really changed the way I view the world around me,” said Will Zuniga, a recent class participant at Hopland REC. “Now that I've taken it, I don't just see plants around me – I see stories. I understand more about the relationship that all of nature's moving parts have with each other. The class has given me more drive to learn about the world around me and to teach others as well.”

Under the UC ANR umbrella, the California Naturalist Program certifies participants through an immersive 40+ hour class delivered by one of its partner organizations, in this case, the California Conservation Corps (CCC). Aged 18 to 25 (and U.S. military veterans up to age 29) and from diverse educational backgrounds across the state, these California Naturalist students worked hard to fulfill the mission of the CCC – to protect and enhance California's natural resources and communities through education and service. 

The California Naturalist Program promotes environmental literacy and stewardship through discovery and action. The program is designed to introduce Californians to the wonders of our unique ecology, engage the public in the study and stewardship of California's natural communities, and increase community and ecosystem resilience. Many other states have similar naturalist programs, but this is the first statewide program in California.

“California Naturalist training allows people of different backgrounds to come together to set what is the standard for how we talk about the sky, the ground below us, and the water that's flowing around us,” reflected Jacob Croasdale, a former class participant. “[They teach us] how to engage respectfully in a way that allows us to both receive and give back to nature.”

Although students graduate with broad knowledge of California's natural wonders, prior knowledge of the course's subject matter is unnecessary. “At first, I thought…I don't belong here. I'm just this artist - what do I have to offer?” shared Monique Wales, another former class participant. “There were Master Gardeners, geologists, biologists and people with crazy amounts of knowledge. But we all came together with such enthusiasm, and we wanted to learn from each other. It was such a fun group.”

“People who are thinking about the California Naturalist program but aren't sure that they know enough to step into something where the language is maybe more technical than they're familiar with should not be intimidated,” added Pete Devine, resident naturalist at Yosemite Conservancy. “A lot of participants are beginners and just generally interested folks. These people belong in the California Naturalist Program.”

A quick peek at the syllabus reveals many themes, field trips and interactions with local experts that culminate in the well-rounded knowledge necessary to help preserve our unique ecosystems. California has an incredibly diverse range of wildlife, habitats, rivers, lakes and coastal resources – wild and urban alike – and ecosystem and community resilience are essential.

After the course is completed, California Naturalists perform service through education and interpretation, stewardship, participatory science, environmental program support, community resilience and environmental justice. To date, certified California Naturalists, together with Climate Stewards (another component of the program), have volunteered more than 250,000 hours, worth over $7 million, in 52 of 58 counties in California.

The relationship between CCC and California Naturalist was piloted at the Hopland REC over the last two years and is now being rolled out across the state with support from the Prop 64 Youth Community Access fund. Overall, the project aims to offer three California Naturalist instructor trainings for 48 youth leaders, 24 California Naturalist certification courses for 480 Corps members, visits to or engagement with over 40 unique cultural and natural resources around the state each year, and 3,840 hours of service-learning outreach through youth-led video capstone projects promoting natural and cultural resources.

Overall (and most importantly), the California Naturalist Program allows corps members to have a solid connection to the “why” of their hard work.

Perhaps if we can all connect a bit more with nature in our backyard, we too will see the stories hidden in the plants, water, animals and land.

Drip irrigation in arid regions can cut greenhouse gas emissions, improve air quality

Study at Desert Research and Extension Center highlights agriculture's sustainability role

Under the blistering sun of Southern California's Imperial Valley, it's not surprising that subsurface drip irrigation is more effective and efficient than furrow (or flood) irrigation, a practice in which up to 50% of water is lost to evaporation.

But a recent study also concludes that drip irrigation can dramatically reduce greenhouse gas emissions from soil – which contribute to climate change and unhealthy air quality in the region – without sacrificing yields of forage crops alfalfa and sudangrass.

“It was really exciting to see,” said lead author Holly Andrews, a National Science Foundation postdoctoral fellow at the University of Arizona. “The crop yield was at least maintained and in some cases increased, but the water use and gaseous emissions were especially decreased under drip irrigation.”

Desert REC crucial to collecting data

Andrews and her colleagues gathered data from field studies at University of California Agriculture and Natural Resources' Desert Research and Extension Center, a crucial hub of desert agriculture research for more than 100 years. Studies in that context are increasingly important, as much of California and the Southwest becomes hotter and drier.

“We already have this history of looking at drip irrigation at this site, so our study was trying to build on that,” said Andrews, who lauded Desert REC's facilities and staff.

In their study published in Agriculture, Ecosystems & Environment, researchers found that – in comparison to furrow irrigation – drip irrigation in alfalfa slashed per-yield soil carbon dioxide emissions by 59%, nitrous oxide by 38% and nitric oxide by 20%.

Nitrous oxide is a greenhouse gas with nearly 300 times more warming potential as carbon dioxide, and nitric oxide is a precursor to ozone and major contributor to air pollution.

While drip irrigation only decreased water demand 1% in alfalfa, the practice led to a substantial 49% decrease in irrigation for sudangrass. For more fertilizer-intensive sudangrass, drip irrigation also reduced soil emissions of nitrous oxide by 59% and nitric oxide by 49% – the result of drip irrigation making those fertilizers more efficient.

Water management can help mitigate climate change

Studying alfalfa and sudangrass – forage crops with very different fertilizer requirements – was a strategic choice by the researchers. They are number one and number three on the list of most widely grown crops by acreage in the Imperial Valley (Bermudagrass, another forage crop, is number two).

With so much land dedicated to producing these crops, the adoption of drip irrigation at scale could deliver significant benefits to residents' health and quality of life.

“The thought that saving water can increase yields while lowering the emission of trace gases that affect regional air quality and Earth's climate is quite encouraging,” said Pete Homyak, an assistant professor of environmental sciences at UC Riverside who contributed to the study. “This is especially true for the Imperial Valley, an arid region where water is a limited resource and where residents are exposed to bad air quality.”

Homyak, who is affiliated with UC ANR through UC Riverside's Agricultural Experiment Station, said that this study illustrates how changes in water management can substantially mitigate agricultural impacts on the environment.

The study findings should encourage growers to replace furrow irrigation systems with drip irrigation infrastructure – especially in combination with financial incentives from the state, such as cap-and-trade and carbon credit programs, that can help defray high installation costs.

“It really is worthwhile if you're thinking sustainability and environmental activism in how agriculture can actually support climate change mitigation,” Andrews explained. “These practices might be a way that we can start to change that picture a little bit – and make agriculture more sustainable by tailoring irrigation management to local climate conditions.”

In addition to Andrews and Homyak, the other study authors are Patty Oikawa, California State University, East Bay; Jun Wang, University of Iowa; and Darrel Jenerette, UC Riverside.
