Racial capitalism and a tentative commons
2020Rachael 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.

2020Françoise Jarrige, Cyril Mumenthaler, Joëlle Salomon Cavin · IRIS · Switzerland (Lausanne)
This chapter described and analyzed the implementation of a new agricultural project on a domain in Lausanne, Switzerland. The innovative process was built through confrontation between stakeholder strategies, with negotiations and adjustments. It appeared that powerful economic and legal constraints limited some expected innovations, particularly regarding land contracts. Ultimately, the anticipated multifunctional agricultural project was implemented through three coordinated structures: an association, a cooperative, and an agricultural enterprise.

2020Cleusa Fernandes Ramos, Andréia Assunção Soares, Isabela Carvalho dos Santos, F. Ramos, Odair Alberton, Luciana Kazue Otutumi, Lidiane Nunes Barbosa, Ricardo de Melo Germano, Daniela Dib Gonçalves, Luiz Sérgio Merlini · Journal of Pure and Applied Microbiology · Brazil
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.

2020John Taylor · Frontiers in Sustainable Food Systems · United States (Rhode Island)
This long-term replicated trial in Rhode Island evaluated the yield performance and soil quality impacts of four small-scale food production systems over three summer growing seasons. While total marketable food yields (2.22 to 2.96 kg m-2) were modest compared to biointensive agriculture (4.64 kg m-2), individual crop yields often exceeded regional and national averages without soil quality loss. The study addresses a lack of experimental research on urban agriculture and provides a framework for normative research, offering more reliable yield estimates for modeling urban production potential.

2020Jennifer Jettner, Mary Secret · International Journal of Social Welfare · United States
This study examined the relationship between race and racial diversity on social capital in community gardens located in food deserts in the southeastern USA. Cross-level regression models were performed on a sample of 52 gardeners from 10 community gardens, analyzing their “sense of community” and the “number of resources” obtainable from fellow gardeners. Results indicated that community gardens are excellent vehicles for promoting one’s sense of community regardless of race or garden’s racial composition, but they were less likely to increase the number of resources. Accessing a greater number of resources took longer and more effort, and increased perceptions of racial diversity had a negative relationship with the number of resources.
Equity & displacementCommunityWelfareWho practices urban agriculture? An empirical analysis of participation before and during the COVID‐19 pandemic
2020Lauren Chenarides, Carola Grebitus, Jayson L. Lusk, Iryna Printezis · Agribusiness · United States
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.

2020Lauren Balotin, Samantha Distler, Antoinette L. Williams, Samuel J. W. Peters, Candis M. Hunter, Chris Theal, Gil Frank, Taranji Alvarado, Rosario Hernandez, Arthur Hines, Eri Saikawa · International Journal of Environmental Research and Public Health · United States (Atlanta)
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.
Contamination & food safetyHealthCommunity8. Diverse Politics, Difficult Contradictions: Gentrification and the San Francisco Urban Agriculture Alliance
2020Michelle Glowa, Antonio Roman-Alcalá · New York University Press eBooks · United States (California)
This chapter examines the San Francisco Urban Agriculture Alliance, analyzing its composition, genesis, and how it has confronted the tensions and limitations of neoliberal urbanization. Based on personal experiences and research, it proposes that justice-driven urban agriculture movements are influenced by political-economic changes and can be absorbed into existing neoliberal and pro-development trajectories. This indicates a critical finding regarding equity and the challenges urban agriculture faces in resisting gentrification.

2020Omanjana Goswami, Ashaki A. Rouff · Soil Systems · United States (Newark)
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.
Contamination & food safetyHealthCommunityThe affordable housing, transportation, and food nexus: Community gardens and healthy affordable living in Calgary
2020Miho Lowan‐Trudeau, Noel Keough, Joshua Wong, Sara Haidey · Canadian Geographies / Géographies canadiennes · Canada (Calgary)
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.

2020Katie L. Butterfield, A. Susana Ramírez · Health Education & Behavior · United States (Minnesota)
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.
