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.

2025Leanne Idzerda, Calin Lazarescu, Tricia Corrin, Eric Vallières, Alix Couture, Sara Khan, Lynn McIntyre, Valerie Tarasuk, Alejandra Jaramillo Garcia · Health Promotion and Chronic Disease Prevention in Canada · Canada
A systematic review (PROSPERO CRD42021254450) searching four databases to 19 February 2025, with duplicate independent screening, risk-of-bias assessment and certainty grading, on food-based interventions that could reduce household food insecurity (HFI) in Canada. Exposure to food voucher programmes may reduce HFI, but exposure to food box, community gardening, school food, hunting and fishing, and food charity programmes may have little to no effect on HFI. The authors conclude that because HFI is primarily an economic problem, food-based responses are unlikely to have a major impact on overall HFI and a more comprehensive public policy approach is required. This is direct counter-evidence to framing community gardens as a food-insecurity intervention.

2025Ana Zepeda, Maria C. Ortíz-Rivera, Clare Cannon, Amanda Crump · The Professional Geographer · United States
This research, conducted in San Juan, Puerto Rico in July 2019, investigates how women experienced the impacts of Hurricane Maria on their urban farms (huertos urbanos). Findings show that while many women enjoy urban farming and it provides fresh produce, almost all women farmers experienced a decline in volunteer participation a few years after the farms' establishment and even more so after Hurricane Maria. Despite this, many women described the urban farms as very important for community food cultivation and gathering.

2025Lucas Velasques, Janaína Wohlenberg, Osmar Manoel Nunes, D. Friedrich, Norton Víctor Sampaio · Revista Científica Agropampa · Brazil (Dom Pedrito/RS)
This field study, involving 20 residents of Dom Pedrito/RS, Brazil, who practice home gardening, aimed to identify motivational factors, difficulties, and benefits. The main difficulties reported were the time required for cultivation and the presence of pests and insects. While benefits included consuming healthy food, health improvements, and supermarket savings, the significant challenges of time commitment and pest management indicate limitations to the widespread positive impact of home gardening.

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.

2024Patsy Kraeger, Rhonda Phillips, J. H. Lubin, Jonathan Weir, Kristina R. Patterson · Sustainability · United States
This study investigated the connection between local farmers markets (FMs), community-supported agriculture (CSAs), and physical well-being at the state level across the 50 states of the United States. Analyzing 2016 data from the United States Department of Agriculture using an ordinal logistic regression model, the study found an inconclusive relationship at the state level. While local FMs and CSAs may increase physical well-being, this study did not find such an increase.

2023Nicholas Greatens, Nick Klejeski, Les J. Szabo, Yue Jin, Pablo D. Olivera · Plant Disease · United States (Minnesota)
In July 2021 and July-October 2022, rust disease was observed on all 20 lemongrass plants in a community garden near Mankato, Minnesota, USA, causing 5-50% leaf loss. Molecular analysis of the rust fungus identified it as Puccinia cesatii or a closely related species. Although P. cesatii has been reported on Cymbopogon species, lemongrass is not generally considered a host, indicating an unusual infection.

2023Sinan Kordon, Patrick Miller · ArtGRID - Journal of Architecture Engineering and Fine Arts · United States (Roanoke)
A survey in five disadvantaged neighborhoods of Roanoke, Virginia, identified primary reasons for non-participation in community gardening. Using descriptive statistics, T-test, and factor analysis, the study found that "theft and damage," "difficult access," "too much effort," and "no personal interest" were the main deterrents. These findings highlight specific barriers to public involvement in community garden projects.

2023Seohyun Kim, Carlos Almeida Peña · Journal of Student Research · United States
This study critically evaluated existing initiatives like SNAP, HFFI, and urban agriculture for addressing food deserts in the United States, which affect approximately 19 million individuals. Through a literature review and interviews, the research found that these programs, while offering some positive impact on food insecurity, largely fail to directly address the fundamental issue of distance and systemic accessibility to supermarkets. The study proposes enhancing public transit and online delivery platforms as comprehensive solutions.

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.

2021Christine Costello, Zeynab Oveysi, Bayram Dündar, Ronald G. McGarvey · Environmental Science & Technology · United States (Chicago)
This study used optimization techniques to assess the land area and radius needed around Chicago, Illinois, to meet nutritional needs. It found that no mix of food items could satisfy vitamin D, B12, and calcium needs within a 650 km radius. While urban agriculture reduced the required radius by 10-15 km, significant nutrient fortification or supplementation was still necessary to localize the food system.

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.

2020Lauren Chenarides, Carola Grebitus, Jayson L. Lusk, Iryna Printezis · Agribusiness · United States
This study examined household-level participation in urban agriculture (community and home growing) before (2017) and during (2020 lockdown) the COVID-19 pandemic in Phoenix, AZ, and Detroit, MI, using two online surveys and bivariate probit models. It found that considerably fewer individuals participated in community gardens compared to home gardening, and overall participation was lower in 2020 than in 2017. The continuity of individuals' participation in growing food at community gardens and home is fragile, and many urban households' food-growing practices may not yet be mainstream, suggesting other barriers inhibit participation.
