2022Ana Clara Aparecida Alves de Souza, Fernando Dias Lopes · Cadernos EBAPE BR · Brazil (Porto Alegre)
This article analyzes an urban collective garden, Horta da Formiga, in Porto Alegre, Brazil, through a two-year participatory investigation using Pierre Bourdieu’s framework. The study found that the more protagonists of Horta da Formiga align with capitals considered legitimate by the state, the more they can reconcile contradictions in this field. However, despite individual agency, participants face structured conditions that do not allow for more organic and diverse forms of contradiction reconciliation.
Governance failureCommunityPolicyEconomicsPromoting an Urban Utopia: The Role of Community Gardens on Community Vitality
2022Kayla Danielle Staley · Digital Archive @ GSU · United States
This quantitative study explored the relationship between community gardens and community vitality indicators (median household income, educational attainment, business establishment, occupied housing units) using U.S. Census Bureau data at the census tract level. While all community garden census tracts showed an increase in median household income by 2013, no direct association was found between community gardens and educational attainment. The research suggests a loose association between community gardens and increased median household income, but the garden's presence cannot be solidified as the sole reason.

CommunityWelfareEconomicsExpelled from the garden? Understanding the dynamics of green gentrification in Vancouver, British Columbia
2022Daniel Sax, Lorien Nesbitt, Shannon Hagerman · Environment and Planning E Nature and Space · Canada (Vancouver)
A case study of an urban farm in Vancouver, Canada, facing displacement due to redevelopment, revealed that urban residents engaged in urban greening can be both implicated in and impacted by green gentrification processes. The study highlighted the power dynamics farm members navigate to preserve land access and found that the farm's identity was co-opted by development agents as a branding tool. This research contributes to understanding the limitations of development processes in accounting for green gentrification risks.

2022Emmanuelle Melis, Emma Louise Armitage, Yuxin Ma, Amelia Weiss, Brian E. Robinson · McGill Science Undergraduate Research Journal · United States (Chicago)
This study investigated the location of urban commercial farms in Chicago, Illinois, and whether there is a significant disparity between the social demographics of production and sale points. All production and distribution points for commercial urban farming companies were geocoded and analyzed against socioeconomic indicator data from the 2016 US census, including median annual household income, mean home value, and percent racialized minority population. Findings revealed statistically significant differences in socioeconomic indicators between census tracts of farm and sale point locations, showing a skewness of farm locations towards lower socioeconomic status areas and sale point locations towards higher socioeconomic status areas. This suggests that while farms are more likely to be located in marginalized neighborhoods in Chicago, most produce grown by these farms is sold in more privileged areas.

Tapia-Palacios, Marisa Mazari-Hiríart, Daniel A. Revollo-Fernández, Alaíde Jiménez-Serna, Marco Covarrubias, Carlos Sumano · Frontiers in Sustainable Cities · Mexico (Mexico City)
This study investigated the needs and commercialization challenges of chinampa producers in Xochimilco, Mexico City, to assess the potential of a green label. The analysis, based on a literature review and producers' mental model analysis, found that unresolved issues like commercialization problems, consumers' unwillingness to pay fair prices, soil degradation, and poor irrigation water quality persist. These issues make it difficult for most producers to bear certification costs, indicating that implementing a green label would likely fail to deliver its intended benefits.
