This study evaluated the impact of the Caramel Connections Foundation (CCF) Seeds of Joy Community Garden in Ontario, California, on social equity, public health, and community engagement. Using a mixed-methods design, secondary data from program records, surveys, and focus groups were analyzed. The findings suggest that the garden enhances social cohesion and contributes to health equity by addressing food insecurity and increasing access to nutritious food, green space, and educational programs.

A pilot study on implementing an indoor urban gardening cart at Drexel University in the United States. Noting that "food deserts" - areas lacking affordable full-service grocery stores and with a high density of fast-food options - exist not only in communities like Philadelphia but also on college campuses, the student group Microgreens Health Outreach Project (HOP) built and implemented a small, free-standing indoor community garden cart intended for use by Drexel University College of Medicine (DUCOM) students, after consulting DUCOM's Office of Student Affairs and the owners of the Health Sciences Building (HSB) on funding, responsibility, space, and permanence. The cart was installed on the ninth floor of HSB in September 2024. The project found little existing literature on indoor urban gardening and so was unable to effectively compare its construction costs against prior work, instead designing a custom-built cart through internet research and price comparisons; communication, funding, and a supportive DUCOM community were identified as crucial to its success. The study recommends future research into microgreen taste preferences and the effectiveness of shared harvesting and community garden rules.

This engaged, reflexive case study analyzed the implementation of a community garden in a condominium in Heliópolis, a high social-vulnerability neighborhood in São Paulo, Brazil, and the participants' motivations, drawing on participant observation, a field diary, and semi-structured interviews. The garden was established through crowdfunding (a "vaquinha virtual"). It contributed to the household budget, expanded the variety of vegetables consumed to include unconventional food plants, and improved diet. It also became a space for recovering affective memories, socializing, an activity for elderly women, and bringing the condominium's children closer to the practice of growing food.

Quintana Roo, Mexico, depends on imported food for more than 60% of state consumption, creating structural vulnerability for the local economy, ingredient freshness, and food autonomy. Using a qualitative, critical-interpretive documentary approach, this review analyzed 27 academic, institutional, and community sources to examine how local initiatives — urban gardens, resilient Maya agriculture, and food cooperatives — contribute to self-consumption, the recovery of traditional knowledge, fair trade, and access to fresh ingredients. These practices help preserve endemic species such as criollo maize, chaya, and achiote, and the review states that such strategies need to be integrated into territorial public policy.

This study used multilevel negative binomial regression to examine the relationship between urban agriculture site locations and sociodemographic and neighbourhood environmental characteristics at the census tract level in Ohio, USA. Findings challenge the idea that urban agriculture is placed in areas with low food access, raising questions about the food-access rhetoric used to promote urban agriculture, a movement critiqued for often being led by upper-class, urban elites, and contribute to debates about the roles of race and gentrification in urban agriculture.

This scoping review maps the existing literature on food access in American Indian and Alaska Native (AI/AN) communities in the United States onto the Social Ecological Model (SEM). A systematic search of PubMed, CINAHL, SocIndex, Academic Search Premier, ERIC and Google Scholar covered publications from 1988 to 2023, followed by deductive content analysis through the SEM lens using qualitative software; 14 articles met the inclusion criteria. Interventions most frequently targeted the "intrapersonal" and "community" SEM levels, while the "institutional" and "public policy" levels were least targeted, with intervention formats including support for community and school gardens, seed provision, traditional foods at school, family and community events, and meal provision. The review found that valuable research has been conducted on AI/AN food access interventions, many spanning multiple SEM levels, and it points to the importance of leveraging strengths such as culturally aligned programs and traditional foods, calling for further collaboration between AI/AN communities and researchers to develop more informed, multi-level interventions.

At a hybrid food and resource center with an attached community garden in California, USA, a longitudinal, sequential explanatory mixed-methods study of 30 patrons (mean age 45.9, 73.3% women) combined quantitative measures (survey and skin carotenoids) with qualitative semi-structured interviews to examine barriers to and facilitators of fruit and vegetable intake. Skin carotenoid levels, a biomarker of fruit and vegetable intake, were largely unchanged before and after (P = .51); among the 26 participants interviewed, facilitators cited included perceptions of quality and alignment with health goals, while barriers included mental health and competing priorities, leading to the conclusion that programs aiming to improve fruit and vegetable intake should prioritize non-diet determinants.

A community outreach and education project in Gonzales, California, was implemented by the organization Savor the Local in partnership with the City of Gonzales and the Community Alliance with Family Farmers, aiming to raise awareness of healthy eating and identify barriers to accessing nutritious food among the city's working-class residents. Activities included distributing an informational pamphlet, a follow-up survey, and support for a community garden and healthy cooking classes. Eight survey participants reported a better understanding of the importance of healthy eating and helped identify some reasons residents were not easily accessing healthy foods; the project reported meeting its goals of increasing awareness and gathering feedback on food-access barriers.

Cherish Duerst, Robert Williams, Jose Lopez, Douglas LaVergne · Journal of Agriculture, Food Systems, and Community Development · United States (Minnesota)

This study surveyed food-pantry customers in the Bemidji area of rural northern Minnesota about access and barriers to gardening in its many forms—residential, container, and community. Although 91% of respondents wanted to garden and 85% had gardened before, only 31% were active gardeners, and the study identifies specific barriers preventing otherwise motivated low-income individuals from gardening, along with participant-suggested solutions within reach of local policymakers.

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.

The work by Max Rousseau and Vincent Béal illuminates the ambiguities of a policy that organizes urban decline and racial segregation in Cleveland. This policy promotes urban degrowth and racial segregation, balancing algorithmic management and urban greening. The study focuses on the Rust Belt region, which experiences de-urbanization marked by the subprime crisis, racism, and segregation.

This paper examined three types of locally oriented Short Food Supply Chains (SFSCs) in southern New England and their spatial alignment with demographic factors. The findings indicate that pay-as-you-go operations are more prevalent in predominantly White areas and, to some extent, higher-income areas. Box share arrangements (community-supported agricultures) showed stronger associations with educational attainment. The study concludes that local food availability is a systematically uneven phenomenon, varying with both outlet type and social characteristics.

This study adapted "Harvest for Health," a home-based mentored gardening intervention for cancer survivors, into a community-based intervention for Arizona's arid desert environment. The adapted intervention, "Harvest for Health Together Arizona (H4H2-AZ)," will enroll participants for two growing seasons (6 months) in 30 ft2 community garden plots, with Master Gardeners providing one-to-one mentorship and gardening supplies. This pilot six-month single-arm intervention aims to determine the feasibility, acceptability, and appropriateness of the adapted program for skin cancer survivors, with secondary outcomes exploring effects on cancer preventive health behaviors and health-related quality of life.

This scoping review explored factors associated with Community Supported Agriculture (CSA) participation among low-income households in the United States. Analyzing 18 articles, findings suggested that women may be more likely than men to enroll in CSA. A lack of familiarity with CSA may hinder enrollment, whereas more education and self-efficacy for food preparation may facilitate participation.

Gundula Proksch, George Lee · · United States

Based on data from the Chicago Urban Agriculture Mapping Project, this study used GIS mapping to investigate urban agriculture typologies and their distribution in the Chicago metropolitan area. It showed that small-scale non-profit gardens are integrated closely with communities, while commercial controlled environment agriculture (CEA) operations utilize existing infrastructure and buildings in commercial and industrial corridors. Both types of urban agriculture serve different needs, providing various benefits to the urban population, from social services to fresh food production and economic development.
