Building Capacity for Food Justice: The Multifaceted Benefits of an Urban Home Gardening Intervention
2026Taylor Swenski, Jocelyn Smith Carter, Marjorie Kersten, Elizabeth Berkeley, K. Varner, Howard Rosing · Ecology of Food and Nutrition · United States (Chicago)
The "Grow Your Groceries Home Garden" intervention program, implemented in Chicago, United States in 2022, aimed to improve food access in food-insecure communities. A longitudinal investigation over two annual cycles surveyed 46 participants, complemented by focus groups with 9 participants, to evaluate food access, cost savings, health, and socioemotional outcomes. While results on improved gardening confidence over time emerged non-significant, participants reported increased food access, cost savings, healthier eating, stress reduction, and strengthened relational bonds.

2024Wendy Demark-Wahnefried, Robert A. Oster, Kerry P. Smith, Harleen Kaur, Andrew D. Frugé, W. Walker Cole, Julie L. Locher, Gabrielle B. Rocque, Maria Pisu, Jennifer R. Bail, Harvey Jay Cohen, Douglas R. Moellering, Cindy K. Blair · JAMA Network Open · United States (Alabama)
A randomized trial in Alabama, USA, assigned 381 older cancer survivors (mean age 69.8 years, 69.0% female) with suboptimal vegetable and fruit intake, physical activity or physical function to a one-year home vegetable gardening intervention (supplies plus mentoring by certified master gardeners) or to a waitlist. The primary outcome — a composite index of improvement in vegetable and fruit intake, moderate-to-vigorous physical activity and physical function — did not differ significantly (4.5% intervention vs 3.1% waitlist, P=.53), nor did vegetable and fruit intake between arms (mean difference 0.3 servings/day, P=.10). The intervention arm did show significant gains in physical performance (2-minute step test +6.0 steps; 30-second chair stand +0.8 repetitions), perceived health (+8.4 points on a 100-point scale) and gut microbiome alpha diversity. The COVID-19 pandemic significantly moderated effects, so the trial does not establish that gardening halts functional decline in older adults.

2024Moses Wanyakha, Nancy Grudens‐Schuck, Ann M. Oberhauser · Journal of Agriculture Food Systems and Community Development · United States (Iowa)
This study investigated resilience and vulnerabilities in fresh produce donation partnership programs to food pantries in Iowa during the COVID-19 pandemic. Findings revealed a significant decrease in labor hours during the pandemic years of 2020–2021, attributed to government policies and social distancing requirements. Volunteer shortages, donation inconsistency, and exclusionary community practices appeared to be inherent vulnerabilities of volunteer-based food donation programs.

2022Julie Cornfield, Harmonii Odinga, Jaleh Kermani, Katherine P. Theall, M. Pia Chaparro · American Journal of Health Promotion · United States (New Orleans)
An environmental assessment of 10 community gardens and interviews with 20 community members and administrators in New Orleans, Louisiana, explored factors affecting garden use. Gardens scored high in design and cleanliness but low in accessibility and information availability. While community members perceived gardens could increase fresh food access, administrators believed gardens could not produce enough food for community-wide impact, emphasizing social benefits instead.

2022S.B. Jilcott Pitts, R.A. Seguin, J. Kolodinsky, E.H. Morgan, M.J. White, M. Sitaker, J.T. McGuirt, W. Wang, K.L. Hanson, A.S. Ammerman · UNC Libraries · United States
This study examined perspectives on food access among 53 low-income families with children participating in a cost-offset community-supported agriculture (CO-CSA) program across nine communities in the US states of New York, North Carolina, Washington, and Vermont. Focus groups revealed that while produce quantity was abundant and affordability was generally good, payment timing was a barrier for some, and unfamiliar foods and quick spoilage hindered acceptability. The study concluded that CO-CSA may facilitate increased access to fruits and vegetables, but perceptions of positive diet change may be limited by challenges in incorporating share pick-up into regular travel patterns and meal planning, with food waste concerns being particularly acute for families with constrained resources.

Scott, Kristine G. Koski · Frontiers in Public Health · Peru (Lima)
In peripheral settlements of the Pachacámac district of metropolitan Lima, Peru, community health promoters delivered a sequence of (1) home and community gardens, (2) 'conscious nutrition' and (3) parenting workshops (ICDP), comparing 113 children aged 0–3 in intervention communities with 127 in control communities at baseline, 8 and 12 months. The interventions significantly reduced the risk of food insecurity (adjusted risk ratio 0.20, 95% CI 0.08–0.51) and of language delay (0.39, 0.19–0.82), but did not significantly improve motor or social/cognitive delay. Multiple micronutrient supplement use lowered motor delay risk (0.12), while households with more pets had higher risk of motor delay (3.24), social/cognitive delay (2.72) and food insecurity (1.73). Because gardens were bundled with nutrition and parenting components, the contribution of the gardens alone cannot be isolated.

2018Zsofia Mendly‐Zambo, Dennis Raphael · Social Policy and Society · Canada
Household food insecurity (HFI) affects over 1.7 million Canadian households, yet government action to address it has been remarkably limited. Non-governmental efforts like food banks and community gardens have depoliticized HFI, complicating solutions. The study argues that the critical materialist political economy discourse, which is least considered, best explains HFI in Canada and offers the most effective response.

2018Shannon Donovan · Case Studies in the Environment · United States (Anchorage)
A multi-faceted needs assessment, including a community survey, stakeholder workshop, and key informant interviews, was conducted in Anchorage, Alaska, to explore the strategic expansion of its community garden system. The study found that demand for community gardens far outweighs supply. To sustainably meet diverse needs, expansion efforts should focus on accessible locations, gardener capacity building, and strengthening partnerships.

2018Walter W. Furness, Courtney M. Gallaher · Local Environment · United States (Rockford)
A study in Rockford, Illinois, examined community gardens to assess their contribution to residents' access to fresh produce and other social benefits. Data was collected through interviews with gardeners, focus groups, and surveys of food pantry users. The findings indicate that while non-gardening community members benefit from increased produce provided by the gardens, they do not receive all the social and communal benefits associated with active garden participation.

2016Mónica M. Gerber, Jennifer L. Callahan, Danielle N. Moyer, Melissa L. Connally, Pamela M. Holtz, Beth M. Janis · International Perspectives in Psychology · United States
This exploratory mixed-methods study investigated the perspectives on community gardening among Nepali Bhutanese refugees (N=50; 62% female) in the United States, comparing gardeners (n=22) and non-gardeners (n=28). Quantitative results showed no significant differences between groups regarding symptoms of depression, anxiety, somatic complaints, or adjustment to life in the US. However, community gardening was significantly positively associated with social support, a finding further supported by qualitative data.

2016Daniel Orlins Trigg · ScholarWorks -A service of University of Vermont Libraries (University of Vermont) · United States
This study investigated food insecurity screening among clinicians in Vermont, where 76% of residents experience some level of food insecurity. It found that physicians and physician assistants prefer using an established two-item screen for food insecurity. However, these clinicians tend to underestimate the actual prevalence of food insecurity in their practice communities.

2015Hugo Puerto · Journal of International Crisis and Risk Communication Research · United States (Florida)
This ethnographic study in Indian River County, Florida, investigated challenges in engaging Mexican im/migrant farmworkers in community-based health solutions, specifically community gardens. Despite efforts by farmworker leaders and the health department to promote community gardens for health and economic benefits, little engagement was observed within the farmworker community. The research, based on participant observation, surveys, and interviews, analyzed barriers to healthy eating and the limited role of grassroots initiatives in improving health outcomes.

2014Katherine Luke · D-Scholarship@Pitt (University of Pittsburgh) · United States (Pittsburgh)
This study used a door-to-door survey in six Pittsburgh, Pennsylvania neighborhoods to measure the impact of community gardens on residents' perceptions of food access. It found that many gardeners do not consider gardening to improve their personal food security, and despite geographic proximity and expressed interest, community garden participation rates were low. Social and emotional barriers, including lack of gardening knowledge and racial prejudice, appeared to prevent residents from becoming active participants.

2008Anne‐Marie Hamelin, Céline Mercier, Annie Bédard · Public Health Nutrition · Canada (Quebec City)
A study in Quebec City, Canada, interviewed 55 food-insecure households and 59 stakeholders to compare perceptions of food security needs and community programs. While both groups agreed on the need for better financial resources, households reported that food quality and access were neglected, and that existing programs, even combined, were insufficient to meet their needs. Stakeholders, however, largely perceived households as satisfied with programs and believed their primary need was a basic amount of food. The study concluded that community programs alone cannot bring about the social change needed to prevent food insecurity.
