This project created an ArcGIS inventory of street amenities in downtown Lewiston, Maine, supporting the Healthy Neighborhoods (HN) organization. A scoring index was developed to compare streets, and a brief assessment of vacant lots was conducted to evaluate future development potential. Findings showed trees greatly outnumbered other amenities, significant variation in sidewalk smoothness with vacant lots more common in flawed areas, and limited, non-uniform distribution of community gardens and open access green spaces.

This study surveyed 41 adults and children (2-12 years) in August 2015 and 23 in February 2016 from low-income households participating in a 50% subsidized Community Supported Agriculture (CSA) program in the United States. Participants' fruit and vegetable intake (FVI) was higher than US averages, and they more frequently met vegetable recommendations. While some seasonal produce was consumed more often when locally in-season, causality between CO-CSA participation and FVI could not be inferred due to potential self-selection bias.

This study used spatial optimization models in the Phoenix, Arizona metropolitan area to identify optimal locations for urban gardens near food deserts and on vacant land. Spatial analysis found that existing gardens are primarily in areas with good food access, providing an alternative food source to only 8.4% of food desert residents. The optimization model, however, identified 53 alternative garden locations that could cover 96.4% of all food deserts, demonstrating a significant improvement over the current distribution.

An online survey of 37 educators (36% response rate) in South Carolina, who completed a school gardening training course between 2012-2015, assessed a pilot farm-to-school initiative. The study found that most educators were unaware their garden was part of the initiative, and gardens were not integrated with school-wide programs, particularly cafeteria meals. However, most educators maintained their gardens for over a year and used them for academic instruction.

The alternative food movement (farmers' markets, community gardens) in San Diego, United States, was investigated in relation to gentrification. Uneven urban food landscapes were shown to be intimately connected to gentrification processes, shaped by race, class, political decisions, and capital flows. Farmers' markets and community gardens are primarily located in affluent and gentrifying areas, providing evidence of a growing appropriation of alternative food spaces by urban developers and cultural elites.

In Oklahoma, tribes have initiated numerous food projects over the past three decades aimed at achieving food sovereignty. However, Oklahoma's complex history, environmental issues, and current politics present challenges such as uneven food quality, poor indigenous health, intratribal factionalism, racism, and a stark dichotomy of affluence and extreme poverty. These factors complicate the creation of self-sufficient food systems and the reconnection of tribal members with traditional foodways.

This descriptive study aimed to describe a social urban agriculture project in a community located in Canoas, Rio Grande do Sul, Brazil. Through a literature review and a semi-structured interview with the project coordinator, it was shown that urban agriculture possesses social, economic, ecological, and symbolic dimensions beyond food production. The study concluded that various projects developed around urban food cultivation, with main impacts including the promotion of food security, generation of employment and income, environmental management, social integration, and development of human capital.

Soil contamination with potentially toxic trace elements and anthropogenic organic pollutants is a widespread problem in urban areas worldwide. While urban agriculture increases food security, potential risks exist without knowledge of urban soil contamination. Lead (Pb) contamination is a widespread and common urban soil issue associated with human health risks, with almost half of US EPA Superfund sites having Pb contamination. Cadmium (Cd) is also a widespread urban soil pollutant, largely from industrial activities like plastic manufacturing, battery disposal, and metal ore processing. The bioavailability of soil Pb to humans is unusually low and generally tied to Pb speciation.

This qualitative fieldwork in a large, urban school district in Northern California explored school food reform efforts addressing childhood obesity. Reforms transpired through three processes: sustained involvement of parent-activists, leadership by the school food service director in championing farm-to-school efforts and facilitating partnerships, and widespread community support for funding and implementation. These findings indicate how local social change transformed public school food programs to benefit youth health.

This ethnographic study, conducted in Boston and Somerville in the summer of 2016, investigated how urban chicken keeping might transform keepers’ thinking about food systems and animal relationships. The research revealed the unexpected discovery of lead contamination in urban chicken flocks in the Boston area, which unsettled the imagined simplicity of urban agriculture and exposed a "metabolic rift." This finding prompted keepers to engage more deeply with the history of the soil and opened new ways of thinking about collective metabolism, multispecies living, and food politics.

A controlled pilot study offered 95 first-time shareholders drawn from a university wellness program a $200 voucher to join a Community Supported Agriculture (CSA) program, surveying food lifestyle behaviors before and after participation and comparing changes against an 82-person control group using econometric analysis. Changes were found in four categories — fresh versus processed food consumption, food prepared at home versus away, food purchasing behavior and interest in nutrition, and self-reported health outcomes — and these changes were more strongly realized among shareholders who reported lower-than-average health prior to the CSA.

This report examines a comprehensive community wellness initiative launched in 2014 in Meadville, Pennsylvania — a town classified as a food desert under USDA criteria, where 26.1% of residents lived in poverty and nearly 13% had poor nutritional status in 2014, and where an estimated 70% of adults regionally were overweight or obese with childhood obesity above 30%. The initiative established community gardens, piloted a fresh fruits and vegetables program in a local elementary school, and launched a mobile farmers market — piloted in summer 2016 in collaboration with the local bus company — targeting a low-income neighborhood to increase access to fresh produce and reduce obesity.

A study examined the structure and meaning of community gardens in Frenchtown, Tallahassee, Florida's oldest and most cohesive African American community. Using a mixed-methods approach during a five-week NSF-funded ethnographic field school with the Health Equity Alliance of Tallahassee, the study analyzed how residents transform empty spaces into places of engagement and empowerment, resisting systemic racism. Through garden activities, residents transcend race, culture, income, and neighborhood boundaries while promoting health, heritage, place-making, and economic opportunities, positioning community gardens as an expression of social resistance.

This study surveyed 22 Community Supported Agriculture (CSA) members receiving weekly vegetable shares in central Minnesota, USA, administering a demographic and anthropometric survey at the season's start and four follow-up surveys on vegetable consumption and food waste, each 10 days after a share pickup. Average BMI was 26.1 ± 4.3 kg/m², average family size was 3.1 ± 1.2 persons, and average distance traveled to pickup was 3.4 ± 5.8 miles; the percentage of vegetables consumed depended on vegetable type and family size but not BMI. Leafy greens were both the most frequently included vegetable and the most frequently discarded; 80% of participants reported increased awareness of food waste from taking part in the study, but only 53% believed their food waste had actually decreased, and awareness showed no correlation with vegetable consumption or discarding behavior.

A study from the University of Illinois at Urbana-Champaign, USA, that identifies soil contamination as a universal concern in urban agriculture and notes that the long-term benefits of alternative soil management systems such as raised beds have not been explored in the scientific literature. Its stated objective is to determine the effects of six soil management options - direct soil with synthetic fertilizer (DSF), direct soil with organic amendments (DSO), raised-bed mixture with synthetic fertilizer (RBMF), raised-bed mixture with organic amendments (RBMO), raised-bed compost-only with synthetic fertilizer (RBCF), and raised-bed compost-only with organic amendments (RBCO) - on yield of kale, garlic, pepper, cilantro and radish, on soil biological, chemical and physical properties, and on ecosystem services such as water and nutrient retention. Data collected include marketable versus cull yield, soil nutrients and organic matter, soil moisture, weed emergence, infiltration rate and bulk density, but this abstract does not report the comparative results themselves.

This study genotyped Giardia duodenalis in raw-eaten vegetables (crisp lettuce, regular lettuce, kale, chicory, and rocket) sampled from street markets and community vegetable gardens in an urban area of southern Brazil. Researchers analyzed 130 samples from street markets and 130 from community gardens (260 total), washing them in Tween 80 solution, filtering through a cellulose acetate membrane, amplifying the GDH gene by semi-nested PCR, and genotyping positive samples by PCR-RFLP. 7.3% (19/260) of samples tested positive for G. duodenalis, from both street markets (10/130) and community gardens (9/130), including both organic and non-organic products. Assemblage AI predominated, but assemblages B and E, which carry zoonotic potential, were also found. The study concludes this points to a need for investigating commercially sold raw vegetables and establishing stricter quality control.
