Using exploratory factor analysis on 363 respondents recruited from U.S.-based agricultural networks, this study developed a survey-based scale to capture what Black- and Brown-led food justice organizations value most about community farming and gardening. The analysis supported a five-factor structure—termed "Agricultural Community Power" (AgCPS), covering collective self-determination, community care, land-based spiritual wellbeing, embodied Earth care, and Ubuntu/interdependence—with adequate reliability (Cronbach's alpha = 0.93).

This 8-week pre-post feasibility study tested a culturally tailored community gardening intervention—embedding Black History Knowledge—among 11 middle-aged African American women in Champaign, Illinois, in summer 2023. Participants significantly increased device-measured daily step count (median +880 steps/day) and fruit and vegetable consumption (median +82 units), with smaller effects on physical activity and perceived stress. The authors conclude the intervention may be a feasible way to improve physical activity, produce intake, and psychological health, though larger, adequately powered studies are needed.

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.

An explanatory mixed-methods study using community-based participatory research and an Indigenous evaluation approach, examining a māla kalo (a community garden growing taro) run by Native Hawaiians living in the continental United States. At the end of the 2023 growing season, 12 volunteers and 5 programme leaders aged 18–75 completed a survey and interview. Satisfaction was high and participants wanted to take part more often; thematic analysis identified connection to self, community and land, learning and sharing knowledge, and connection to culture. With only 17 participants and no health outcome measures, the study cannot establish health effects — it documents how a community garden growing a traditional staple can serve as a site of cultural connection for a displaced Indigenous community.

An evaluation of VeggieRx, a produce prescription programme anchored to the Farm on Ogden — a 20,000-square-foot urban agriculture facility opened in 2016 in a historically disinvested food desert in Chicago, Illinois, by the Chicago Botanic Garden together with Lawndale Christian Health Center. Clinicians refer patients to the farm for free produce boxes, nutrition counselling and cooking classes. Using a retrospective, propensity-score-weighted cohort design covering January 2016 to December 2021, the study compared 680 VeggieRx participants with 978 weighted controls and found a mean body weight difference of −6.71 pounds (−4.7% of body weight) at eighteen months. Because the design is observational rather than randomised, residual confounding such as selection by motivation cannot be excluded.

A quasi-experimental study in Mexico with 21 adults over 65 evaluated a community urban garden intervention for nutritional status. Participants showed increased nutrition knowledge, a 47.7% rise in vegetable intake, and a 23.8% increase in physical activity. However, anthropometric variables did not show significant differences, indicating limited impact on physical measurements despite positive changes in knowledge and habits.

An integrative literature review investigated the potential of Community-Supported Agriculture (CSA) to promote food security in Brazil. CSA can ensure a decent income for family farmers, reducing social vulnerability, and shows significant potential for promoting food sustainability due to its strong influence from agroecology. However, CSA faces a significant limitation in the elitization of this movement, reflecting historical social inequalities where only a relatively small portion of the population can afford healthier food.

This study aimed to develop safe community garden sites in Miawpukek First Nation, Newfoundland, Canada, addressing potential soil contamination. Soil testing revealed inorganic arsenic levels exceeding Canadian agricultural guidelines. Hügelkultur-style raised beds with imported soil were used, resulting in undetectable arsenic in potatoes grown there, while potatoes from contaminated soil exceeded safety limits. Kale grown in both raised beds and native soil remained within safety limits.

Tamanda Chabvuta · Western Journal of Communication · United States

This paper examined resilience narratives about a community garden in a predominantly Black neighborhood in the United States during a period of recovery from COVID-19 disruptions. Applying the communication theory of resilience, the analysis revealed themes of honoring legacy, belief in community and sharing, maintaining external collaborations, and persistence despite a lack of internal involvement. The study highlighted the critical role of external collaborators and community history in resilience efforts.

This 10-week study in Tucson, Arizona, examined the role of a collaborative urban garden in addressing food security and social isolation among nine university students, refugees, and asylum seekers. Using pre- and post-study surveys, interviews, and observations, researchers found that both groups experienced positive impacts on food access and social connections. The results indicate that urban gardening creates pathways to empowerment and equalizes differences between the groups and society.

This review article analyzed the effects of school urban gardens on environmental education and child nutrition in public institutions of Metropolitan Lima. Examining 25 national and international scientific studies using the PRISMA methodological approach, findings showed that school gardens strengthen ecological awareness and promote fruit and vegetable consumption. However, structural barriers such as lack of resources, teacher training, and sustained institutional support were also identified.

Katie L. Butterfield, Kathryn P. Daniels · Wellbeing Space and Society · United States

This study analyzed 34 in-depth interviews with rural and urban community garden organizers across the United States to compare perceptions of health benefits. Rural participants emphasized the holistic community orientation of their gardens, while urban participants highlighted their gardens as natural spaces and a driver for interacting with nature. The findings demonstrate varying impacts of community gardens in rural and urban settings.

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.

This study analyzed 87 multidrug-resistant (MDR) bacterial strains from leafy greens (n=29), root zone soil (n=42), and bulk soil (n=16) in Washington, D.C. urban agriculture systems using whole genome sequencing. The isolates, spanning 4 phyla and 14 genera, carried diverse antimicrobial resistance genes (ARGs) and mobile genetic elements (MGEs). The results indicate that MDR bacteria are present in urban agriculture systems, including on fresh produce, dominated by soil-associated taxa carrying diverse ARGs and MGEs, which suggests implications for resistance mobilization.
