A citywide cluster-randomized trial assigning 541 Philadelphia vacant lots across 110 geographic clusters to a greening intervention, a minimal mow-and-clean intervention, or control. Shooting incidents fell significantly in the greening arm (-6.8%, 95% CI -10.6 to -2.7) and the clean-and-green arm (-9.2%, 95% CI -13.2 to -4.8), with no evidence of displacement to adjacent areas. Concludes that inexpensive, scalable vacant-land remediation significantly reduces shootings resulting in serious injury or death, and recommends cities pilot place-based interventions to reduce firearm violence.

Published 1 November 2019, tracing the Ford Foundation's 1968 experiment in Program-Related Investments — $10 million authorised by its board — in the context of civil-rights-era support for Black entrepreneurship. It lent $500,000 to Leon Sullivan's Progress Plaza shopping centre in Philadelphia and generated a multiplier of roughly five dollars of outside investment for each Ford dollar. Yet some businesses failed and doubts surfaced early about whether foundations had the financial expertise required, raising the question of whether philanthropy should work inside the existing economic system or challenge it more directly.

This review proposes that the lens of "racial capitalism" can illuminate the contradictory motivations and outcomes of urban agriculture (UA). It examines how UA can contribute to racial Othering, the racialization of space, and dispossession on the one hand, while enabling struggles of resistance and self-determination on the other. The author uses this framework to address how settler-colonial logics persist in the contemporary North American city.

Lucy O. Diekmann, Leslie C. Gray, Gregory A. Baker · Renewable Agriculture and Food Systems · United States (Santa Clara County)

This research evaluates how three types of urban gardens in Santa Clara County, California—home gardens, community gardens, and community food security (CFS) program gardens for low-income families—contribute to food security using a multidimensional framework. In summer 2015, median production ranged from 26 kg (CFS participants) to 56 kg (home gardeners), enough for at least one adult to meet federal vegetable guidelines; interviews further showed gardeners valued knowledge, control, freshness, flavor, organic methods, and cultural acceptability, not just quantity.

Dietlinde Heilmayr, Howard S Friedman · Journal of Health Psychology · United States

Framing community gardening as a promising but under-evidenced multifaceted health intervention, this paper presents one of the first experimental studies on the topic. The results showed promise for aspects of community gardening while underscoring the need for more rigorous methodologies, and the article offers a framework for studying the health effects of community gardening and similar multifaceted health-promotion efforts.

McClintock N. · Annals of the American Association of Geographers · USA

Demonstrates how urban agriculture becomes entangled in eco-gentrification, arguing that eco-gentrification is not merely a side effect of an urban sustainability fix but is central to how racial capitalism operates through green urbanization.

Egerer M., Fairbairn M. · Geoforum · California, USA

Under rapid urbanization on California's central coast, social tensions permeate garden boundaries and shape internal relations. Conflicts over membership rules, resource management, and theft of produce erode community cohesion within the gardens.

Daniele Eckert Matzembacher, Fábio Bittencourt Meira · British Food Journal · Brazil

This exploratory case study investigated two Brazilian Community Supported Agriculture (CSA) initiatives over two years and six months using participant observation, ethnography, interviews, and secondary data. It found that the analyzed CSA activities integrate social, environmental, and economic sustainability dimensions, providing guaranteed sales and higher incomes for producers, and emphasizing sustainability education for consumers. The findings cannot be extrapolated to broader populations due to the exploratory nature of the study.

Nathan McClintock, Christiana Miewald, Eugene McCann · · North America

This chapter explores urban agriculture (UA) as fundamentally political practices, examining its role in neoliberal governance and sustainability policy-making, and as an object of contestation. It relates UA motivations and practices to processes of urbanization and political economic restructuring. The chapter highlights that UA is a site of political contestation, arising from broader political economic shifts.

Juliana Maantay, Andrew Maroko · International Journal of Environmental Research and Public Health · United States (New York City)

This study examined whether proximity to community gardens in less affluent neighborhoods is associated with an increased likelihood of gentrification, using Brooklyn, New York as a case study. Employing GIS and spatial analysis, the results suggest that proximity to community gardens is associated with significant increases in per capita income over a five-year period. This indicates that environmental improvements, such as community gardens, may paradoxically spur gentrification and the displacement of existing lower-income residents, raising concerns for environmental justice.

Mark Paul · Journal of Agrarian Change · United States (Massachusetts)

This paper evaluates the livelihoods of Community-Supported Agriculture (CSA) farmers in the Connecticut River Valley of Massachusetts from their perspective. Results indicate that while CSA farmers earn more farm income than other U.S. farms on average, they still earn far below the median national income and generally fail to earn a living wage. Despite these economic findings, farmers stressed the importance of broader social, ecological, and economic benefits to farming. The study concludes that CSA has largely failed to provide adequate livelihoods for farmers to date.

Wanda Martin, Lindsey Vold · Health Promotion and Chronic Disease Prevention in Canada · Canada (Saskatoon)

This qualitative case study examined how participation in the "askîy" urban agriculture project in Saskatoon, Canada, empowered young adults and built food-growing capacity. Seven interns (aged 19-29) participated in 2015, and their experiences were analyzed using a sustainable livelihoods framework. Findings indicated that collaborative engagement fostered connections, influenced grocery shopping habits towards more vegetables, and motivated interns to continue gardening and apply their knowledge in their home communities.

Lindsey Elaine Thomas · Journal of international women's studies · United States

This honors thesis explored how kindergarten and first-grade teachers in the United States use expository texts in science lessons related to a garden project. The project involved creating a book set of nonfiction texts on gardening topics and observing teachers' use of these books. The goals were to research teachers’ use of expository texts in science lessons for a garden project and to find effective ways to incorporate Massachusetts reading standards with science in the classroom.

Zsofia Mendly‐Zambo, Dennis Raphael · Social Policy and Society · Canada

Household food insecurity (HFI) affects over 1.7 million Canadian households, yet government action to address it has been remarkably limited. Non-governmental efforts like food banks and community gardens have depoliticized HFI, complicating solutions. The study argues that the critical materialist political economy discourse, which is least considered, best explains HFI in Canada and offers the most effective response.

This work proposal focuses on school gardens as a means to develop environmental education and food themes, connecting theoretical and practical concepts to aid interdisciplinary teaching and learning. It aims to foster students who value agricultural principles, noting advances in students' methodological conception of Field Education despite regional challenges from the agro-industrial sector.

Leandro Nascimento Bertoldi, Pamela Johanna Menéndez Velásquez · Revista panorama/Panorama. Cuba y salud · Brazil

A course on Agroecology was conducted in Jequié, Bahia, Brazil, focusing on creating organic community gardens and training communities in health promotion, disease prevention, and food and environmental education. The project identified farmers who transitioned from using agrotoxins to biological control, resulting in increased local biodiversity and encouraging community gardening. The initiative also fostered social empowerment, increased self-esteem, and developed collective discussion and production practices within the SUS.

Sarah Lowndes · · United States (Detroit)

The extent of Detroit's economic problems was mired in secrecy prior to its bankruptcy declaration. Significant tensions persist regarding the city's future direction, exemplified by the ongoing saga of the half-built Wayne County jail. Simone DeSousa agreed that the growing significance of community gardens in Detroit has been an important part of residents re-imaging their city.

E. C. Barrett, J.A. Kowalski · Journal of Extension · United States

In two urban counties in the United States, Extension educators developed an on-site program, including a demonstration kit and planning protocol, to address the integrated pest management (IPM) needs of community gardeners. This program provides practical, research-based information to community gardeners, allows Extension to maintain a presence in urban centers, and offers outreach to audiences who may not have historically used Extension resources.

Renata Blumberg, Rosa Huitzitzilin, Claudia Urdanivia, Brian C. Lorio · Capitalism Nature Socialism · United States (New Jersey)

This article examines the challenges and possibilities of community gardening in small, peripheral cities with large immigrant populations, using concepts from feminist geography and food justice research. Focusing on the "Raíces Del Sur" community garden in Passaic, New Jersey, as a case study, it argues that these concepts provide a useful framework for enacting ecofeminist visions through community gardens. The study emphasizes the need for greater ecofeminist engagement with community gardening initiatives in cities throughout New Jersey.

NEPEA (Interdisciplinary Center for Research and Extension in Agroecology) in Goias, Brazil, was established to foster sustainable rural development. The center focuses on ecologically based farms in Southeast Goiania, conducting research on sustainable agriculture and tree arrangements for the rehabilitation of degraded areas. It also carries out extension activities in schools, promoting and implementing school gardens and pedagogical nurseries.

Lorrilee McGregor, Pamela Toulouse, Marion Maar, Nancy L. Young · International Journal of Indigenous Health · Canada

A narrative analysis of eight focus groups with 33 caregivers in six First Nation communities in Canada explored determinants of dietary decisions. Caregivers identified changes in food systems due to factors like wage economy participation, low income, hunting/fishing regulations, and processed food availability. These factors have altered food systems and influenced dietary choices, leading communities to pursue initiatives such as community gardens, freezers, and hunting camps to regain food sovereignty.

Shannon Donovan · Case Studies in the Environment · United States (Anchorage)

A multi-faceted needs assessment, including a community survey, stakeholder workshop, and key informant interviews, was conducted in Anchorage, Alaska, to explore the strategic expansion of its community garden system. The study found that demand for community gardens far outweighs supply. To sustainably meet diverse needs, expansion efforts should focus on accessible locations, gardener capacity building, and strengthening partnerships.
