College students eligible for food assistance deterred by confusing requirements

Food pantries like this one at UC San Francisco supplement student food access. Extra requirements for college students to qualify for SNAP or CalFresh deter many from receiving the food beneftis.

Modifying Farm Bill could reduce barriers to SNAP for students and improve nutrition

Inadequate access to food can harm college students' health and academic performance. A recent University of California research study in the Journal of Nutrition Education and Behavior investigated why UC students who are eligible for the federal Supplemental Nutrition Assistance Program (SNAP) – the nation's largest food assistance program – do not receive the benefit.

“Based on our study findings, eliminating the extra requirements for college students to qualify for SNAP would go a long way in ensuring that more eligible students get the support they need to meet their basic food needs,” said study coauthor Lorrene Ritchie, director of the UC Nutrition Policy Institute, which is part of UC Agriculture and Natural Resources.

A 2015 study by NPI found four in 10 UC students didn't have enough money to buy sufficient food for a healthy lifestyle. To promote better health, UC has taken steps to ensure students are aware of SNAP, established campus food pantries and other basic needs resources.   

"In California, SNAP is known as CalFresh and despite policies and communication to improve college students' access to CalFresh, participation remains low, with approximately 78% of those eligible not receiving benefits," said lead study author Suzanna M. Martinez, associate professor in the Department of Epidemiology and Biostatistics at UC San Francisco.

For insight on why low-income UC students aren't receiving the benefits, Martinez, Ritchie and colleagues at UC San Francisco and Nutrition Policy Institute consulted county agencies that process student CalFresh applications. The researchers interviewed county staff in nine counties that are home to UC campuses: Alameda, Los Angeles, Merced, Orange, Riverside, San Francisco, Santa Barbara, Santa Cruz and Yolo.

While CalFresh benefits have mainly been paid by the federal government through the Farm Bill, counties contribute and county agencies are responsible for implementing policies, determining eligibility, processing applications and distributing funds.

“With the Farm Bill still up for reauthorization, these findings could provide insight into how to strengthen SNAP policy related to eligible students,” Martinez said.

The researchers conducted focus groups and interviews with county staff to determine how agency workers interpret the complex criteria for students to meet CalFresh eligibility.

Their questions focused on how students' applications differed from those of community members, steps taken when processing student applications, student-specific training and suggested improvements to the process.

Five central themes were identified in the interviews: 

  • More consistent policy dissemination and program administration is needed
  • Student exemptions and the application process are perceived as challenges for students
  • Key supports for successful student applications include carefully reviewing applications for potential exemptions, providing useful resources to students, and campus partnerships
  • Tracking policy changes is burdensome
  • Eliminating student rules and treating students as regular clients would be more equitable

The researchers found that CalFresh rules are challenging for students as well as the county agency staff.

Also, eligibility requirements, written over 50 years ago, are based on the assumption that college students are supported by middle-class families.

The research supports simplifying the student CalFresh process to increase participation for eligible students, especially for historically underrepresented racial and ethnic groups and low-income students for whom equitable access to CalFresh benefits is critical.

“Once students get confused or don't know what they need to do, they don't follow through with their application,” one CalFresh eligibility worker told the researchers.

During the COVID-19 pandemic, some federal and state requirements were waived or relaxed for students.

“The timing of this study resulted in a natural experiment since COVID-19-related SNAP modifications streamlined the student application process and reduced administrative burden,” Martinez noted. “These modifications alleviated some challenges discussed by county workers, confirming existing opinions to eliminate the student rules.”

Ritchie said, “We hope our research informs policy to remove some of the barriers so students no longer have as much difficulty getting the food they need.”

This study was funded by the California State Legislature, which provided funding to the University of California to address students' basic needs (UC Basic Needs Initiative).

Grape seeds, stems and skins can reduce dairy cattle emissions

Low-cost wine industry additive also improved feed efficiency and milk quality

Researchers at University of California, Davis, added fresh grape pomace left over from winemaking operations to alfalfa-based feed for dairy cows and found that methane emissions were reduced by 10% to 11%.

The preliminary findings could offer a low-cost sustainable pathway for vineyards to reduce waste while helping dairy operations maintain quality while cutting back on emissions of methane, which is a powerful greenhouse gas.

“This is the first time anybody has shown that this can work in California,” said Ermias Kebreab, an animal science professor and associate dean of global engagement at UC Davis. “You're reducing emissions, you're improving the quality and it may also reduce the cost of production.”

The pilot research project, which will be detailed in a paper later this year, also found that mixing in grape pomace improved feed efficiency and increased healthful fats, said Selina Wang, an associate professor of Cooperative Extension in small scale fruit and vegetable processing.

“We found that the feed with the additive of grape pomace changed the fatty acid composition of the milk and, in particular, increased the polyunsaturated fats, which are the main fats in grape pomace,” Wang said. “This suggests that supplementing the feed with an optimal fatty acid profile may have positive impact on the fatty acid profile of the milk and increase their health benefits.”

Symbiotic commodities?

In 2022, California was the leading dairy producer in the country, generating $10.40 billion in sales, while 90% of wine production came from the Golden State, with a market value of $5.54 billion.

Processing grapes for wine generates thousands of tons of waste in the form of grape pomace, which consists of leftover seeds, skins and stems. Dairy and livestock are responsible for more than half of the state's methane emissions, owed largely to cow burps.

They are the top two agricultural commodities in California, according to state production statistics, and reducing waste and emissions for both industries are key to the state meeting its climate goals.

Tannins for emission reductions

Wine grapes are high in fats and tannin, which is known to reduce methane emissions, so Kebreab sought to test if adding grape pomace to feed could have a positive effect while not adversely affecting production.

“It's a byproduct that's not being used much,” he said. “This is something that can be included in our efforts to try to reduce emissions.”

A mix of feed options

To do the research, scientists worked with Holstein dairy cows and gave the animals feed consisting of alfalfa, wheat, almond hulls, cottonseed and grain. After two weeks, the cows were split into three groups: A control group with no change in diet, another where the feed combination included 10% grape pomace and a third that received 15% grape pomace.

Every four weeks, the cow groups would change feed combinations.

They were fed twice daily by postdoctoral students and interns, and emissions were monitored daily. Milk production was documented in the morning and evening and milk samples were collected weekly to analyze for fat, protein, lactose and other measurements, which showed no differences between the control and other groups.

Methane and hydrogen emissions were reduced compared with the control group, suggesting that grape pomace reduced enteric emissions without affecting production.

“I think the dairy industry will be very interested in this,” Kebreab said. “Sometimes when you're using additives, they have palatability issues. With grape pomace, they absolutely love it.”

Next on the list is a trial with olive pomace and working to understand the mechanism that reduces emissions. “If we have a better understanding of the mechanisms, we can select the feed additive or a mix of feed additives to reduce dairy cattle emissions and make dairy milk healthier while making use of the agriculture byproducts,” Wang said. “There's a lot of room to grow in this space and we're excited about this work.”

The research was supported by the California Dairy Research Foundation.

Connecting California’s forest landowners with California Tree School

While trees and forests are often emblematic of constancy in a fast-paced world, our state's forests are actually changing before our eyes. Since 2020, the UC ANR Forest Stewardship Education (FSE) program has been helping California's forest landowners be proactive about the inevitable shifts their forestland will experience. The Forest Stewardship and Post-Fire Forest Resilience workshop programs use an online educational format, which guide landowners through the basics of creating forest management plans and managing post-fire landscapes, respectively. Now, the FSE team is piloting a new program to engage a wider audience of forest landowners and community members passionate about trees.

This spring, the Forest Stewardship and UC ANR Fire Network teams are holding the first California Tree School, where individuals attend multiple in-person classes on the forestry topics they are most curious about. “The existing online programs are very focused on forest management plans and post-fire activity, and [Tree School] lets us tackle other topics,” said UC ANR forest and natural resources advisor Susie Kocher.

A one-stop shop for continuing forestry education

California Tree School was inspired when Forest Stewardship Academic Coordinator Kim Ingram, Post-fire Academic Coordinator Katie Reidy and Kocher attended Oregon State University Extension's Tree School event in Clackamas County, Oregon. OSU Tree School is a day-long experience comprised of classes that cover the different dimensions of forestry: constructing a house from your own timber, carbon cap and trade, and buying portable sawmills are just a small sampling of the options for attendees. OSU Tree School students ranged from forest landowners to community college students, contributing to a space which would facilitate community connections as well as learning.

Kocher described the experience as a “a great one-day, one-stop shop to keep up-to-date on what we [forest landowners and professionals] should know.” Excited by the breadth of opportunities offered at OSU's Tree School, Ingram, Kocher and Reidy were inspired to bring the format to California.

“It's our time to discuss the whole ecosystem,” noted Reidy. “Tree School is bringing in the trustworthy, reliable group of experts who can provide more information on the questions pertaining to landowners' specific goals.”

California Tree School will be offered in two locations this spring, with CA Tree School- Hopland taking place on May 4, and CA Tree School- El Dorado on June 1. Similar to OSU's Tree School, attendees are expected to be a mix of forest landowners, natural resource professionals and interested community members.

Connecting statewide professionals; personalizing forestry education

Tree School offers attendees the opportunity to focus on subjects that pertain to their specific learning needs. This personalized approach is a new foray for the Forest Stewardship team, but is something that Ingram says workshop participants have been wanting for some time.

“Our participants never think they learn enough. They are always asking for more information, and this Tree School gives us the chance to expand on things we might not have had a chance to go over in the workshop series,” remarked Ingram. Additionally, Tree School instructors had creative freedom when it came to developing their classes, from the topic to the class format. This is evident when browsing through each session's class catalog. CA Tree School attendees choose four classes to attend, meaning they can build their first burn pile, understand the ins and outs of regional wildlife, paint outdoors and learn how to aid statewide reforestation efforts all in one day.

“I felt that Tree School created a sense of trust around complex topics,” noted Reidy about her experience last year in Oregon. For CA Tree School, the Forest Stewardship team aims to do the same. This meant recruiting from throughout the UC ANR network and other organizations, including CALFIRE and CARCD (California Association of Resource Conservation Districts), to bring trusted voices to the community.

“What's exciting about Tree School is that we are bringing natural resource professionals from all around to engage everyone at the same time, and all in one place,” noted Ingram.

CA Tree School is an opportunity to connect professionals and community members in person.

The team is excited to see all the connections that will be made between community members and professionals during this pilot year, and “if this is successful and we can bring it back next year,” commented Kocher, “we are definitely interested in partnering with more people and expanding our outreach.”

Making CA Tree School an in-person experience was important to the team, as much of the education is hands-on. Additionally, Kocher sees enhanced potential for building personal connections: “In person, you have this opportunity for people to identify as part of a community,” noted Kocher, “So I'm excited for people to hang out with each other.”

Encouraging an informed community

“You can't separate the emotional from the physical, and there are a lot of topics in forestry like wildfire and economics that can be a bit of a downer,” said Ingram. “I'm excited to help create a positive learning environment, and one that encourages folks to turn to UC Cooperative Extension for these resources.”

“Our main goal here is to get science out there,” concurred Reidy. “The more exposure people have to science, the more confident they feel in themselves and their wants and needs.”
