This study, based on 24 interviews with urban agriculture (UA) leaders in Sacramento, California, identifies three "taproots" of UA projects: justice, health, and market. The analysis reveals how these roots interact differently with racial capitalism, creating disparities in their growth trajectories. Specifically, UA projects associated with the justice taproot are historically underrepresented and undervalued.

In the Nhapindazal neighborhood of Irati-PR, Brazil, a community garden project was implemented by the PET – Engenharias Group in partnership with "pastoral da criança." The project aimed to supplement food conditions and improve dietary habits for socially vulnerable families. Through a community meeting with representatives, plans for the garden's construction, maintenance, materials, and plant species were discussed. Academic students actively participated in the installation, and the community organized to maintain the garden, resulting in improved and diversified diets for those consuming its produce.

This study investigated remediation strategies to reduce heavy metal uptake in soil from a potential community garden lot near a railroad in Lincoln, NE, where elevated concentrations of lead (Pb) and arsenic (As) were detected. In a greenhouse experiment, romaine lettuce was grown. Biochar amendment resulted in the lowest concentrations of Pb and As in lettuce leaves and stems, whereas coffee grounds amendment led to the highest concentrations across all tested plant parts.

The REACH program of the Kaiser Permanente Northern California pediatrics residency aimed to develop a school-based gardening program for middle-school students to promote nutritional education. A needs assessment of 278 students revealed 33% experienced food insecurity and 51% consumed more than one sugary drink daily. After only three classes, 12 participating students reported improvements in eating at least five vegetables daily (from 58% to 66%) and in nutrition knowledge (from 20% to 50% accuracy in completing a "healthy plate").

Emotional well-being (EWB) during household gardening and other activities was measured in the Minneapolis-St. Paul Area, USA, using an app-based Day Reconstruction Method. Among 370 participants, 118 (32%) reported engaging in household gardening. Gardening EWB ranked among the top 5 out of 15 activities for three average EWB measures and was not statistically different from biking, walking, and eating out. Average net affect of gardening was significantly higher for vegetable gardeners, low-income gardeners, and women, while companionship, race/ethnicity, and urban versus suburban location showed no significant difference.

This 2020 study in Brazil evaluated the bacteriological quality of six medicinal plants from community gardens, including Cymbopogon citratus and Aloysia citriodora. Analysis of cold extracts revealed bacterial contamination, with Plectranthus barbalus showing the highest aerobic mesophile count and Aloysia citriodora the highest coliform count at 45°C. However, the study concluded that heat treatment (boiling for teas) can significantly reduce or eliminate this bacteriological contamination, making the plants safe for consumption.

A process evaluation of the Farm Fresh Foods for Healthy Kids (F3HK) randomized trial, conducted across 4 states and 12 farms, assessed whether cost-offset community-supported agriculture could improve diet quality among children in low-income families. Intervention households (n=305) purchased a 50% subsidized share of local produce and were invited to nutrition classes. Results showed the mean CSA season was 21 weeks, with a median CSA pickup rate of 88% of the weeks. Most adults (77%) and children (54%) attended at least one class, and 82% of caregivers reported consuming most or all produce.

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.

This cross-sectional online survey assessed nutrition policies, practices, and environments in 113 Georgia SNAP-Ed elementary schools from 2015-2017. While most schools had wellness policies and provided nutrition education, fewer had policies limiting sugar-sweetened foods in classrooms or established school gardens. Minimal significant differences were found across school-level demographics.

This study investigated Atlanta residents' knowledge regarding heavy metal and metalloid (HMM) exposures and remediation in urban agriculture, following the detection of industrial slag and hazardous soil contamination in West Atlanta in 2018. Through surveys and follow-up interviews, it was found that participants were concerned about the potential health effects of soil contaminants but unconcerned with produce in their gardens. Gardeners' knowledge of HMM exposure sources and remediation methods was low and varied based on racial group.

This exploratory study surveyed 21 parents from a campus-based preschool in the northwest United States during the 2017-2018 school year to understand the impact of the "Harvest of the Month" program on children's nutrition behavior at home. Findings indicated that a variety of program foods were served and consumed at home, but parents prioritized knowing food origins over serving local foods. Parents' knowledge of farm to ECE, reported farmer's market purchases, and CSA participation were limited, suggesting a need for targeted parent education.

Soils from seven community farms in Newark, New Jersey, USA, were analyzed for lead (Pb) concentration and speciation. Single-step extractable Pb concentration ranged from 22 to 830 mg kg−1, with 21% of samples exceeding the NJDEP limit of 400 mg kg−1 for residential soils. Lowest Pb concentrations were detected in raised beds, while uncultivated native soil and parking lot samples had the highest values. Although most Pb is associated with reducible and oxidizable soil fractions, indicating a lower risk of mobility and bioavailability, Pb exposure through ingestion and inhalation pathways remains a concern when directly handling the soil.

This study estimated the population-level effectiveness and cost-effectiveness of a subsidized community-supported agriculture (CSA) intervention in the United States. A microsimulation model developed in 2019 utilized national demographic, biomedical, and dietary data (NHANES, 2013-2016) and a randomized trial (Massachusetts, 2017-2018). Two interventions were modeled: an unconditional cash transfer ($300/year) and a subsidized CSA ($300/year subsidy), both of which were shown to reduce discounted disability-adjusted life years (DALYs) for cardiovascular disease and diabetes complications. Both interventions had negative incremental cost-effectiveness ratios, implying cost savings to society.

This study, examining community gardens in Calgary, aimed to determine the socio-economic demographics of neighborhoods supporting community gardens and their proximity to active transportation and public transit. GIS visualization and quantitative analyses were used to investigate relationships between demographic variables and transportation accessibility. Findings showed that community garden neighborhoods are located in areas with significantly fewer visible minorities, higher levels of educational attainment, and more attached dwellings like apartments and townhomes. This study suggests potential inequities in the proliferation of public community gardens based on socio-economic factors beyond economic capital.

A quantitative content analysis was conducted on descriptions, missions, and goals provided by 411 community garden managers across Minnesota. Six frames were consistently present, including "greater good" and "community orientation," which were the most common. The findings suggest that the prevalent "greater good" frame may inadvertently reproduce inequality by alienating food-insecure populations, similar to other alternative food programs.

This cross-sectional survey in two low-income, predominantly African American neighborhoods in New Orleans, Louisiana, interviewed 901 participants to explore factors associated with acquiring food from farmers markets (FMs) and community/home gardens (C/HGs). Daily fresh fruit and vegetable servings were positively associated with acquiring food from FMs and C/HGs in the past three months. African Americans and those living farther from an FM were less likely to acquire food from an FM, while those who cooked at home were more likely to use C/HGs.

This study measured the social, educational, civic, and nutritional impacts of four types of urban food system activities: home gardens, community gardens, farmers' markets, and CSAs, through a survey of 424 gardeners and 450 direct market shoppers in California's San Francisco Bay Area. While nutritional impacts were consistently high, significant differences were observed in social interaction and civic engagement between activity types. Gardens generally fostered greater learning, connection, and civic participation than direct marketing.

An experience report describes the implementation of a community garden in a Long-Term Care Institution for the Elderly in Fortaleza, Ceará, Brazil, in 2018. The activity aimed to promote a welcoming eco-social environment and a recreational activity for the well-being of the elderly. Developed through interdisciplinary integration between Nursing and Agronomy courses, it provided an opportunity to learn about the residents' personalities, stories, and aspirations. The implementation of the community garden significantly contributed to the well-being of the elderly, broke the monotony and feelings of abandonment, and enabled the use of an unused space.
