This study evaluated chemical and biological soil-health indicators at 21 urban-to-periurban sites in Chicago (home gardens, community gardens, institutional farms, and private urban farms). It measured soil fertility, nematode trophic composition and food-web indices, and concentrations of lead, arsenic, and zinc; nematode communities differed by management scale and were likely influenced by soil organic matter and pH. Lead, arsenic, and zinc were below levels of concern, and soil fertility was significantly increased by management, particularly in community gardens and urban farms.

This study used choice experiments and latent class analysis in North America to quantitatively examine what drives consumer preferences for growing food in community gardens. It found that providing tools and guidance were the most important contextual factors for participation, that proponents were characterized by high subjective knowledge and perceived benefits, and that opponents had low knowledge. The authors suggest the findings can inform policies promoting sustainable urban food systems.

At an urban community garden in San Diego, in-ground vegetables and fruit trees accumulated lead and arsenic, showing urban garden soils can contaminate food crops; raised beds with clean soil eliminated detectable contamination.

· Agriculture and Human Values · New York City, USA

Contrasts two New York community gardens to reveal tensions between 'green aesthetics' and 'food justice,' arguing that an aesthetics/beautification orientation can align with gentrification and marginalize the needs of low-income communities of color.

Butterfield K. L. · Sociological Perspectives · USA

Analyzes how community garden locations relate to neighborhood composition, showing an uneven distribution in which gardens are not necessarily sited where most needed; ethnicity, income, and education shape access and can produce green-space inequity.

A city-wide mapping of active food gardens in Salvador, Bahia, Brazil, followed by site visits and interviews with gardeners. Only 18 active food gardens could be located in the whole municipality; 17 took part (8 communal, 9 private). Gardeners averaged 55.76 years old and were 52.9% male overall, but women made up 87.5% of communal-garden gardeners and had higher education levels. For 52.9% of respondents the garden was their main source of income; 82.4% ate the produce, 70.6% also sold it and 47.1% donated. Fifty-nine neglected and underutilized species (NUS) were recorded, with 76.5% of respondents reporting they eat 19 of them. The gardens supply affordable food and food diversity without government support — but the very small absolute number of active gardens in a city of this size is equally part of the finding.

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.

This research investigates consumers' perception and acceptance of urban agriculture through a qualitative, exploratory field study with 19 residents from a major metropolitan area in the southwest U.S. The concept mapping procedure was used, and data were analyzed using content and semantic network analysis. Consumers' perceptions of urban farming related to environment, society, economy, and food attributes. The study found a much higher number of positive associations than negative, signaling that consumers would likely accept farming in close proximity, though individual perceptions varied greatly.

Vatsi Meneghel Danilevicz · Psicologia & Sociedade · Brazil (Bahia)

This experience report details the journey of a community garden at a Family Health Unit (USF) in southern Bahia, Brazil, aiming to revive local knowledge and create visibility. Using a cartographic methodology, the study analyzed the garden's effects on participants' health and the bond between health workers and service users. The garden, primarily involving around ten poor, elderly Black women residents, proved to be a powerful tool for therapeutic support, relationship building, cultivation of medicinal plants, reduction in allopathic medication use, and production of vegetables and fruits for participants' consumption.

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.

This article presents observations and suggestions from the operations of Lettuce Harvest Foundation (LHF), a grassroots urban agriculture nonprofit in Vancouver, Canada, founded in 2019. LHF's programming was designed to address challenges posed by the COVID-19 pandemic. The findings suggest that short-term emergency food relief is insufficient, and propose harnessing pre-existing industry elements as a method for grassroots organizations to mitigate food system strains during crises.

This study analyzed the impact of urban agriculture on food security in community gardens in the city of Maringá, Brazil. The research was carried out using the EBIA method, with descriptive statistical analysis and multiple linear regression procedures. The results indicate that the activity did not contribute to the food security of people who depend on the resources generated, whether for consumption or income.

Ada P. Smith · Collaborative anthropologies · Canada

In Canada's Gitxaała Nation, the potential of the Gitxaała community garden and the summer reading program at Lach Klan School as a "food literacy" learning platform for achieving food security and food sovereignty was explored. This research suggests that hands-on learning activities integrating local Indigenous language and knowledge have the potential to contribute to food sovereignty goals by better equipping students to shape their food system.

It maps the combined action of socio-spatial and socio-territorial movements for agroecology in São Paulo and its Metropolitan Region. The study discusses concepts of agroecology, urban and peri-urban agriculture, and socio-spatial/socio-territorial movements as analytical tools, concluding that combined action is necessary for agroecology's expansion.

Rachael Baker · · United States (Detroit)

Farming on Detroit's vacant land has been used for blight reduction and food cultivation since the 1970s, supported by initiatives like Farm-a-Lot. However, in 2015, the mayor’s office directly transferred 40 acres of city-owned land to a for-profit urban agriculture business in Detroit’s east Poletown, raising concerns about equitable resource distribution.
