This GIS-based study of Kalamazoo, Michigan, analyzed how accessibility to different types of food access points — full-service grocery stores, farmers markets, community gardens, food pantries, and convenience stores — differed between low-income and higher-income census tracts. All full-service grocery stores were accessible via bus routes, but 11% of residents in low-income areas lacked adequate access, living beyond the 0.25-mile walkable distance to bus routes. "Positive" access points such as community gardens, food pantries, and farmers markets were found to be concentrated in areas that already had grocery store access, whereas "negative" access points — convenience and dollar stores, which provide lower-quality, highly processed food — filled the access gap in lower-income areas instead. More than twice as many low-income residents had walkable access to convenience stores as higher-income residents, with 81% of those convenience stores located within low-income tracts.

A systematic review of quantitative empirical research on the sustainability effects of community-supported agriculture (CSA) covered 39 studies. Fewer than 30% of the studies assessed ecological sustainability aspects, but where CSA farms were compared to reference systems, they mostly performed better on resource use efficiency and greenhouse gas emissions. Most studies assessed social aspects; many showed that CSA still fails to reach low-income households, so members do not represent the average population, while CSA membership was associated with improved health and sustainability behavior. Economic variables were assessed in more than half of the studies, but knowledge of CSA's relative economic performance remains scarce, though early studies indicate high economic viability. The review calls for more research on ecological aspects specifically, comparisons across farming and marketing systems, and integration of knowledge from theses and practical sources in multiple languages.

Just after NYC announced expansion of mandatory residential organics collection by 2024, the mayor's office eliminated funding for the city's community composting program. The article identifies three failures reflecting national trends: government 'composting' programs that actually rely on anaerobic digestion, centralized processing that concentrates environmental burdens in vulnerable neighborhoods, and mandatory government programs undercutting community composters' viability.

Hantz Woodlands, a large-scale tree farm on Detroit's east side, acquired roughly 2,600 parcels and still holds about 2,000. It bought an initial 1,550 parcels for $540,000 and later resold about 10% of its holdings for $9.5 million — nearly nine times its original cost — while paying only $7,035 of the $33,110 it owes in blight-violation fines. Critics note the Detroit Land Bank Authority never reclaimed a single Hantz property despite missed deadlines, even as it repossessed land from ordinary residents who fell behind.

K. Michelle Glowa · Journal of Agriculture Food Systems and Community Development · United States (California)

This paper reflects on the engagement between Mexican and Salvadorian farmers at the Beach Flats Garden in Santa Cruz, California, and local educational institutions. It discusses the garden's role in critical food system education, highlighting its function as a space of resistance to gentrification in a competitive land market. The garden provides examples of noncapitalist exchanges and decolonial foodways, emphasizing traditional agroecological knowledge.

Sina Razzaghi Asl, Anahita Azadgar · Frontiers in Sustainable Food Systems · Iran (Tehran)

A study in Tehran, Iran, mapped the spatial distribution and socio-economic attributes of 26 urban community gardens using semi-structured interviews, qualitative analysis, and secondary data from the 2020 Tehran statistical yearbook. The findings revealed a geographical distribution imbalance, with most gardens located in the southern part of the city. Community gardens were mainly placed in areas with lower average land prices, lower median household income, and higher education graduates, indicating an uneven distribution that favors socio-economically disadvantaged areas.

This paper focuses on mobility issues in the southern region of Curitiba, Brazil. It points out that the benefits of urban agriculture, particularly the ecological advantages of short food circuits, are hindered by the isolation of its growers. The lack of accessibility in peripheral areas, due to distance or insufficient infrastructure investment, suggests a loss of opportunities in utilizing the transport system.

Daniel 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.

"A Recipe for Gentrification" is an edited volume exploring the complex relationship between intent and impact at the intersection of alternative food systems and urban development. The book aims to unpack how food systems can both drive and resist gentrification. It shows that well-intentioned efforts to increase food access in a neighborhood can be an early initiator of gentrification, and urban agriculture and public green spaces are frequently co-opted for development efforts.

The contemporary industrial food system is problematic, producing diverse foods for a small elite and replicating past labor injustices rooted in colonialism. Urban agriculture is a growing global trend and is expected to be the future of food production. The future of food will also diversify what we eat, including aquaponic tilapia, sprouts, algae, fungus and yeast-derived foods, and imitation meats.

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.

A survey of 88 urban poor individuals in Benin investigated their profiles and constraints affecting participation in allotment gardens. Findings revealed low educational and income levels, overcrowded and unsanitary housing, and limited access to social services and health facilities among the participants. Furthermore, 76% of them experienced food insecurity, and engaging them in allotment gardens was constrained by requirements for farming skills, financial capital, and safety issues.

This study examined school garden prevalence in 148 K-12 schools across four low-income New Jersey cities between 2010-2011 and 2017-2018, before and after the Healthy Hunger-Free Kids Act (HHFKA) of 2010. Garden prevalence increased from 19% in 2010-2011 to 32% in 2013-2014, but this increase was not sustained over time. Furthermore, schools with a majority Hispanic student enrollment had approximately half the odds of having a garden compared to schools with a majority Black student enrollment.

Organic stores, trendy coffee shops, and food initiatives generally associated with the alternative food movement, such as farmer's markets and community gardens, have become a clear symbol.

Héritier Mesa · Cahiers d études africaines · Congo (Kinshasa)

This article explores social trajectories and inequality dynamics among informal workers in Kinshasa, focusing on labor relations within the informal economy. Drawing from ethnographic data on street bread, second-hand clothing, and urban agriculture, the study finds that limited access to capital constrains many workers to sell their labor power with weakened bargaining power, revealing unequal social positionalities.

In April 2021, a panel discussion on food security in Canada took place during the COVID-19 pandemic. This article aims to make visible the vulnerabilities and structural injustices embedded within Canadian foodscapes through different perspectives on food security and justice. COVID-19 rendered many of the structural injustices of food security in Canada more visible.

Gamuchirai Chakona · · South Africa

A study surveyed 314 randomly selected households in four peri-urban settlements in South Africa to assess dietary diversity and food security. Findings revealed generally low dietary diversity and high levels of food insecurity across all sites, with male-headed households experiencing worse conditions than female-headed households. Food insecurity was linked to high poverty, unemployment, and low education levels.

Elizandra Flávia Araujo, Marcos Paulo Fuck · Cadernos de Ciência & Tecnologia · Brazil (Curitiba)

This study aimed to identify and characterize different categories of urban agriculture practitioners in Curitiba. A descriptive study using bibliographic and documentary analysis found that urban agriculture activities are concentrated in peripheral areas of the city, with most participants having a monthly family income of up to two minimum wages. Despite a wide range of actors engaging in these practices, their visibility and inclusion in the political agenda occur asymmetrically.

A comprehensive environmental and social life cycle assessment of perlite, peat, and coir growing media, imported to Spain from Turkey, Germany, and the Philippines respectively, was conducted for urban rooftop farming. Environmentally, coir had the lowest burden, while perlite had the highest impacts due to mining and transport. Socially, peat performed best, but coir showed the worst scores in community infrastructure and human rights, and perlite performed lowest in health and safety.

Cecilia M. Tsu · Amerasia Journal · United States

This article examines community gardens established for refugees from Vietnam, Cambodia, and Laos in the United States during the 1980s. It argues that refugee gardeners perceived a significant disconnect between their rural lives in Southeast Asia and the role of vegetable growing in the U.S., despite advocates emphasizing continuity with their past. The gardens provided a measure of economic empowerment, but highlighted the disjuncture in their resettlement experience.

Mkwela Hawa · Journal of Geography and Regional Planning · Tanzania

This study used a qualitative approach to examine land injustices faced by urban farmers in Mbweni-Mpiji, a sub-urban area of Dar es Salaam City, Tanzania. Findings indicated that farmers experience constant pressure from land insecurity, inferior land rights, informal land access, stiff competition from other land users, degrading land quality, and a continuous decrease in agricultural land size. These factors negatively impact the daily livelihoods, including food security, social status, and income, of those entirely dependent on urban farming.

Lucia Di Paola · · Italy

This paper examines Milan's Porta Nuova re-urbanization project (2004-2015), which features Vertical Forest skyscrapers as symbols of urban greening. Activists and resident groups strongly opposed the project, criticizing the privatization of a public park and high rents, arguing it represents a top-down privatization leading to exclusion and gentrification. In response, these groups developed a public community garden in the same neighborhood as an alternative model for democratic horizontal urban greening.

"No Place to Grow" is a 2019 documentary film (27 mins) that captures the story of a longstanding LatinX community garden, its farmers, neighborhood protests, and negotiations with government officials in the United States. The film depicts the challenges faced by the community garden, leaving viewers disheartened. It is recommended for libraries collecting on community gardens and urban agriculture.

Salvatore Engel‐Di Mauro, George Martin · · Global

This chapter examines the global relationship between food growing and capitalism over 500 years, identifying three profit-seeking formats: mercantilism, industrialism, and global financialization. It argues that capitalism has led to a de-industrialization of cities and a commodification of agricultural products by corporate megafarms, contributing to green gentrification in urban redevelopment. This has incited a food resistance trend, leading to the emergence of community gardens and farms.

Christina Ergas · · United States

This chapter explores urban ecovillages in the United States, highlighting challenges faced by ecovillagers in a neoliberal context. It examines cultural conflicts between sustainability and consumer culture, and points out the exclusive, upper-class, white nature of the local food movement in the US. Monetary and time constraints have made local organic food an elite phenomenon, often cited as a first step to gentrification in urban communities.
