Homeless people cultivate food, better health while gardening in Alameda County
Fresh fruits and vegetables are essential to a healthful diet, but it's hard to keep perishable foods on hand if one doesn't have a refrigerator or a home. To enhance the health of homeless people, the CalFresh Healthy Living, UC Cooperative Extension team in Alameda County has partnered with the South County Homeless Project to grow fresh produce for people staying at the emergency housing in Hayward.
For the past seven years, CalFresh Healthy Living, UCCE Alameda has been delivering nutrition lessons to residents of the South County Homeless Project, part of Building Opportunities for Self Sufficiency. The classes include Rethink Your Drink, Food Safety, Making Every Dollar Count, Eat Healthy Be Active Community Workshops, and Fresh from the Garden.
The South County Homeless Project facility houses 24 people for up to a year. With the help of the CalFresh Healthy Living, UC Cooperative Extension team, its existing garden was refurbished and redesigned. The large outdoor garden behind the facility offers therapeutic gardening opportunities to residents and provides food for their meals.
"I love the garden and when the cook cooks the vegetables, they taste amazing,” said one resident. “I am thankful for this garden and for having the CalFresh Healthy Living team.”
At one time, South County Homeless Project's backyard featured a flower garden. After years of neglect, weeds overtook the garden.
In 2022, CalFresh Healthy Living, UCCE Alameda proposed getting residents involved in growing food by resurrecting the garden with edible plants.
“Not only could we continue to engage residents in nutrition education classes, but we could also work together to reinvigorate their neglected garden,” said MaxFairbee, nutrition educator withCalFresh Healthy Living team,UCCE Alameda.
More than 15 varieties of herbs and vegetables planted
Residents and staff set out to replace the weedy beds with a vegetable and herb garden.
“We worked with South County staff and residents on the design, clean up, planting, harvesting and ultimately incorporating food from the garden into the kitchen for residents to enjoy the fruits of their labor,” Fairbee said.
For gardening expertise and support, Fairbee enlisted the UC Master Gardeners of Alameda County's Community Garden Team to help. While the CalFresh Healthy Living, UCCE staff continued providing nutrition classes, the UC Master Gardener volunteers trained the residents on the basics of gardening.
In April, after heavy rains, the group planted 50 seedlings, half donated by the UC Master Gardeners. They planted two varieties of lettuce,arugula, four varieties of tomatoes, zucchini, kale, onions, cucumbers, green beans, Swiss chard, kale, basil, cilantro, tarragon, thyme, parsley, rosemary, oregano and mint.
From garden to table
“In May, we harvested lettuce and in June, we harvested green beans, cucumbers, kale and onions,” Fairbee said.
The fresh vegetables and herbs were used to prepare salads, sandwiches and pasta dishes for the residents. Fairbee and the other educators have also used the fresh produce for cooking demonstrations and tastings as part of their Fresh from the Garden class.
"We have been able to use many of the veggies as sides or to go in the salad," said one of the South County Homeless Project cooks.
"One of the chefs used the zucchini in the pasta sauce, it was so good! I didn't really know you could use it that way!" said a resident.
After tasting summer squash andgazpacho made with tomatoes from the garden, a South County resident namedSelina said, "I was surprised how good the raw summer squash tasted and how the flavor was different after it was cooked. I'll definitely be adding more zucchini to my plate."
Challenges to keeping the garden going
To keep the garden healthy, they faced competition with plant-chewing snails, slugs and aphids and cats digging in the soil. Because the water source is over 200 feet from the garden, they run a long hose across the main path, along the parking lot to water the plants, then unhook the hose and stash it indoors after each use so that it won't get stolen.
Another challenge of maintaining the garden is getting enough residents and staff to volunteer to work on it.
“Although staff are supportive of the garden, none actually have time to work in the garden,” Fairbee said.
The residents harvest, wash and store the produce in the kitchen. Only four to six of the 24 residents are typically interested in working in the garden, pulling weeds and protecting the plants from pests – most are focused on getting a new job and a home. South County residents usually leave the temporary housing within a few months.
For more consistent garden maintenance, Fairbee is looking to other community groups for volunteers. He is also hoping to persuade the county government to install a water spigot close to the garden so they can install drip irrigation to water the garden.
“We'd like to work with the UC Master Food Preservers to teach residents how to preserve herbs and vegetables,” Fairbee said.
He hopes South County Homeless Project residents will continue gardening in their new homes to grow fresh vegetables so they can enjoy a more nutritious diet and better health.
Beyond the fresh food, the South County Homeless Project residents and staff enjoy the ambience of the garden.
"It's really nice to go back there and just sit, it's really peaceful," said one staff member.
A resident added, "(The garden) relaxes me from stress. I love the garden."
Organic strawberry yields boosted by technique refined through UCCE research
Anaerobic soil disinfestation helps suppress weeds, disease without fumigants
Troubled by puny plants, low yields and persistent mite problems, third-generation Southern California strawberry grower Glen Hasegawa was ready to give up on his transition from conventional to organic 12 years ago.
“I've always liked a challenge – but it turned out to be more of a challenge than I thought it would be!” he said.
But then, with the help of scientists including Oleg Daugovish, UC Cooperative Extension strawberry and vegetable crop advisor in Ventura County, Hasegawa tried a technique called anaerobic soil disinfestation (ASD). When applied correctly, the multi-step ASD process creates a soil environment that suppresses pathogens and weeds and makes for healthier, more robust crop growth.
“Back in the day, it was really hard to get the plant growing vigorously in organic,” said Hasegawa, owner of Faria Farms in Oxnard. “So we started using the ASD and then you could definitely see that the plant had more vigor and you could grow a bigger, better plant using it.”
Seeing that he could produce yields “in the neighborhood” of those grown in conventional strawberry fields fumigated with synthetic fumigants, Hasegawa was able to expand his original 10 acres of organic strawberries to 50 acres.
“I guess you could say I'm kind of a convert,” he said, noting that he now applies ASD to all his acreage each year in late spring.
Joji Muramoto, UC Cooperative Extension specialist in organic production based at UC Santa Cruz, has been experimenting with ASD since it was first brought to the U.S. from the Netherlands and Japan in the early 2000s. Carol Shennan, a professor in the Department of Environmental Studies at UCSC, and Muramoto were among the first to try the technique in California. They found that ASD successfully controlled an outbreak of Verticillium wilt – caused by the pathogen Verticillium dahliae – at UCSC's small organic farm in 2002.
Since then, Shennan, Muramoto, Daugovish and their colleagues have seen encouraging results at 10 trial sites across the state.
“We demonstrated that ASD can provide comparable yields with fumigants, in side-by-side replicated trials,” Muramoto said.
ASD promotes host of beneficial changes to soil ecosystem
ASD comprises three basic steps: incorporating a carbon source that is easily digestible by microbes in the soil (traditionally, rice bran has been used), further encouraging fermentation by covering the soil with plastic to limit oxygen supply, and finally adding water through drip irrigation to initiate the “anaerobic” decomposition of the carbon source and maintain the three-week “cooking” process.
The resulting cascade of chemical, microbiological and physical changes to the soil creates an ecosystem that is both conducive to strawberry growth – and inhospitable to pathogens and weeds.
“It's not like a pesticide where you have a mode of action, and thus resulting in ‘A' and ‘B' for you,” Daugovish explained. “There's a sort of cocktail of events that happens in the soil; they all happen interconnectedly.”
Compared to similar fields that did not undergo the process, ASD-applied organic strawberry fields across California have seen yields increase by 60% to 70% – and even doubling in some cases, according to Daugovish.
The UCCE advisor also shared the story of a longtime grower in Ventura County, who came to him with fields in “miserable” condition; they were plagued by one of the world's worst weeds, yellow nutsedge, and infected with charcoal rot, a disease caused by the fungus Macrophomina phaseolina. But after applying rice bran and following the ASD recipe, the grower saw phenomenal results.
“The only complaint he said to me was, ‘Now I have too many berries – we have to have more pickers to pick the berries!'” Daugovish recalled.
Via researchers' meetings, online resources, on-farm demonstration trials and word of mouth from peers, use of ASD by California strawberry growers has grown significantly during the past two decades. Tracking the purchase of rice bran, Muramoto estimated that about 2,500 acres were treated by the ASD-related practices in 2023 – covering roughly half of the 5,200 total acres of organic strawberries in California.
Muramoto directly links the growth of California organic strawberry production – which now comprises about 13% of total strawberry acreage in the state – with the increasing adoption of ASD.
“If you remove the acreage with the applied rice bran over the last 10 years or so, organic strawberry acreage is just flat,” he said.
Within the last decade, acreage of organic strawberries with ASD-related practices increased by 1,640 acres, which is a boon for air quality, human health and long-term soil vitality. According to Muramoto's calculations, that increase in organic acreage translates to a reduction of about 465,000 pounds of fumigant active ingredients that would have been used in growing conventional strawberries.
“There are hundreds of reports of acute illnesses related to fumigation in the record, so it's very important to find alternatives to fumigants,” said Muramoto, citing California Department of Pesticide Regulation documents.
Research continues to make ASD more economical, effective
The popularity of ASD has come at a price, however, for organic strawberry growers.
“There's more organic out there, and I think most of the organic guys are using it, so there's more demand on the rice bran; the price has been steadily going up every year, like everything else,” said Hasegawa, adding that he has been trying to decrease the amount of carbon while maintaining ASD's efficacy.
On top of greater demand from other growers and from beef cattle and dairy producers (who use rice bran as feed), the price also has increased due to higher costs in transporting the material across the state from the Sacramento Valley. So Daugovish and his colleagues – including Peter Henry, a U.S. Department of Agriculture plant pathologist – have been searching for a cheaper alternative.
“We all want an inexpensive, locally available, reliable, easy to use and functional carbon source, which sounds like a big wish list,” Daugovish said.
Carbon sources such as bark, wood chips, or compost are ineffective, as the crucial ASD microorganisms are choosy about their food.
“Microbes are just like cows; you can't feed them straight wood; they get pretty angry,” Daugovish explained. “And if you feed them something with too much nitrogen, they can't digest it – they get the runs. Microbes are the same way – you have to have the right proportion of stuff so they feel comfortable doing what they're doing.”
In search of an ideal replacement, researchers tried and ruled out grass clippings, onion waste, glycerin and coffee grounds. Finally, they pivoted to a material with properties very similar to rice bran: wheat bran, in the form of wheat middlings (also called midds, a byproduct of flour milling) and dried distillers' grain (DDG, a byproduct of ethanol extraction).
After field experiments in Santa Paula, the UC and USDA researchers found that midds and DDG were just as effective at controlling soilborne pathogens and weeds as rice brain – but at 25% to 30% less cost. Their results were published last year in the journal Agronomy.
“Not surprisingly, the wheat bran has worked almost exactly the same as rice bran,” Daugovish said.
He and Muramoto are now conducting trials with wheat bran at commercial fields, and the initial results are promising. Daugovish said the grower at one site in Ventura County has seen a 90% reduction in Macrophomina phaseolina, the causal pathogen of charcoal rot, in the soil – and an 80% to 90% drop in yellow nutsedge germination. They are waiting for final yield numbers after the coming summer.
While ASD has been beneficial to organic productivity and soil health, both Daugovish and Muramoto acknowledged specific limitations in suppressing the “big three” strawberry diseases: Verticillium wilt, Fusarium wilt and charcoal rot. In coastal areas with cooler soil temperatures, for example, ASD can actually exacerbate the latter two diseases, as the fungal pathogens feed on the rice bran.
“We know it works at warmer temperatures, but, practically, it's hard to do in coastal California,” Muramoto said. “It would be nice if we can find a way to suppress Fusarium wilt at a lower temperature, but we don't have it right now.”
That's why researchers emphasize that ASD is not a “silver bullet.” It's just one tool in the organic toolbox, which includes careful crop rotation, disease-resistant strawberry varieties and better diagnostic tests that help growers pinpoint outbreaks and make the application of various methods more targeted and more efficient.
And scientists will continue to optimize ASD to make it more effective and economical for growers in the different strawberry regions of California – from the Central Coast to the Oxnard Plain.
“We know it can work really well; it's just finding the most sustainable way to do this in our region,” Daugovish said. “We've got to just have an open mind and keep trying.”

Harnessing the Magic of the Soil Food Web: Turning Dirt into Gold. Soil is the foundation for life providing habitat, recycling wastes and toxins, providing structural and nutritional support for plants. Over the past 150 years, more industrial practices have replaced natural methods that degrade soil structure and degrade populations of soil organisms, weakening the natural control of soil borne diseases and pests. This has contributed to a reliance on the use of chemical fertilizers, insecticides and herbicides. These chemicals not only affect the soil, but the biodiversity of organisms that rely on the soil and the plants that grow in it. Nurturing soil is one of the best things you can do as a gardener. Plants thrive in soil that is teeming with life.
Kit Veerkamp, UC Master Gardener volunteer in El Dorado County, will discuss why this really matters and how to modify your soils to improve plant health and reduce disease and pests.

Study: Government shutdown stressed food assistance program participants
A U.S. federal government shutdown can represent a minor inconvenience, a delay in paychecks, or – for people living in some of the most difficult circumstances – an extended period of hunger and anxiety.
A study published recently in the journal Nutrients provides a unique glimpse into the shutdown experiences of participants in CalFresh – California's name for the federally funded Supplemental Nutrition Assistance Program (formerly known as food stamps). Currently, about 42 million people participate in SNAP across the U.S.
In focus groups conducted in 2019 with 26 low-income CalFresh participants from four diverse California counties, participants shared how the 2018-19 federal government shutdown affected their SNAP benefits, their perception of the program and their faith in government.
One of the immediate effects of the 2018-19 shutdown was that February CalFresh benefits were distributed in January. And while that meant program participants saw extra benefits that month, they then had to wait 40 to 44 days until the March issuance – much longer than the usual 28 to 31 day cycle.
“What we saw with this study is that this extended lag in benefit receipt from January to March was devastating,” said Wendi Gosliner, senior researcher and policy advisor at the Nutrition Policy Institute of UC Agriculture and Natural Resources, and an author of the study funded by UC ANR.
She recalled one participant who, despite having a gastrointestinal issue that requires a special diet, had to eat canned food from the food bank that made her sick – rather than go hungry while waiting for her March benefits. Others described cascading financial challenges after using rent money for food in February, or going into debt to pay for food and getting behind on other expenses.
The study also chronicles the experiences of a woman who was anguished to hear the suffering of her daughter, also a CalFresh participant: “She called me several times crying, ‘Ma, I don't – we don't have enough food. What am I going to do…? You know, I can't afford to this and this and this.' And I can't help her.”
For individuals grappling with food insecurity, the stress of feeding their families was compounded by the uncertainties of the government shutdown. And while many participants exercised their agency and resourcefulness in coping with the situation, they also felt a degree of powerlessness amid the “confusion and craziness,” as one person put it.
“No one knew how long that shutdown was going to last; no one knew if the March benefits were going to be paid,” Gosliner said. “And as we learned, there were all kinds of stories circulating out there about what was going on with the uncertainty – a lot of people didn't have the information about what was actually happening.”
Some participants, seeing the “double benefit” in January 2019, thought that it was the last-ever distribution and that SNAP was ending. Others described being unable to get in touch with the CalFresh agency to get their questions answered about the benefits. Most participants had not heard about the disrupted benefit schedule before receiving the benefits. As a result, many people in the focus groups shared that their overall faith in government had been shaken.
Improving customer service, boosting benefit levels and adjusting eligibility and benefit formulas to reflect high cost-of-living and expenses related to working were three recommendations that came from the focus group participants.
A fourth recommendation tackles the shutdown issue head-on: Don't let it happen again.
“Congress should do absolutely everything in their power to be sure that the program operates on the usual time schedule – even if the government is shut down,” Gosliner said.
In the context of the global pandemic, when financial and social inequities and physical and mental health disparities have been laid bare, ensuring access to healthful food is even more important. And with studies showing that hospitalizations increase with longer lags between SNAP distributions, Gosliner said the “absolute last thing” the overburdened health system needs is more people in emergency departments seeking acute care.
“It's the worst time to be having people who need money to feed their families face additional insecurity,” she said. “It's critically important that Congress acts to be sure that there is not any disruption in benefits.”
The authors of the study, “Participants' Experiences of the 2018–2019 Government Shutdown and Subsequent Supplemental Nutrition Assistance Program (SNAP) Benefit Disruption Can Inform Future Policy,” are Wendi Gosliner, Wei-Ting Chen, Cathryn Johnson, Elsa Michelle Esparza, Natalie Price, Ken Hecht and Lorrene Ritchie.
