This paper, focusing on Toronto, identifies subtle impediments to scaling up urban agriculture beyond self-provisioning, despite land not being an insurmountable barrier. These include taxation systems assuming agriculture is a strictly rural activity, inadequate knowledge sharing among urban producers, limited access to soil, water, and seeds, and a lack of incentives for landowners. Achieving 10% of the city's commercial fresh vegetable demand requires significant policy and program initiatives in five key areas, including governance, coordination, and financing.

Kevin Wonch · Hope College Digital Commons (Hope College) · United States (Detroit)

This study examines urban farming in Detroit, a city experiencing rapid decline with a population under a million, limited access to fresh food stores, and extensive vacant land. While arguing for modern urban farming as a foundation for sustainable practices and positive development, it notes that some political and business analysts question its ability to make a significant impact on the city’s future.

Martijn Koster, Pieter A. de Vries · Focaal · Brazil (Recife)

This article examined slum dwellers' politics in Recife, Brazil, as a realm of possibility where care and recognition are central. A community leader's urban agriculture project, which from an outsider's perspective might be considered non-viable, provided slum dwellers with possibilities to strive for community solidarity and personal recognition. The article concludes that slum politics is about claiming the right to be counted and recognized, and about the care for the other.

Sjsu ScholarWorks, Gabriel R. Valle · · United States

This paper explores the self-valorization of work in community gardens as a path to environmental justice, arguing that community gardens disrupt capital's system by removing food as a commodity and revaluing time outside market-driven speed. The Chicano community, being susceptible to workplace inequalities, has a particular stake in this self-valorization, as these inequalities are reflected in unhealthy communities, economies, and environments. The study suggests that self-valorization through work creates natural wealth, reconstructing time, oppression, and communities.

An experiment on assessing and managing soil quality for urban agriculture was conducted during the 2011 and 2012 growing seasons on demolished vacant urban lots in Youngstown, Ohio. Soil compaction was identified as a primary constraint, with high bulk density values of 1.79 g cm⁻³ for in-ground plots and 1.55 g cm⁻³ for raised beds. Crop yield data from 2011 showed that both compost-amended and compost + biochar-amended plots had significantly greater crop yields than control plots, with compost + biochar plots achieving the highest harvest index values.

The 2009 tomato late blight pandemic in the eastern United States resulted in significant crop losses for many home gardeners and organic producers. This event led to widespread questions regarding its causes and differences from previous epidemics.

Toni Y. Sims-Muhammad · · United States (South Louisiana)

This project examined the impact of Hurricanes Katrina and Rita on existing food systems in Lafayette, Acadia, Evangeline, St Martin, and St Landry parishes, with a focus on home and community gardens. The researcher interviewed 57 home/community gardeners and farmers and conducted a survey on pre- and post-Katrina/Rita food sustainability problems, challenges, and perspectives on future food systems.

D. Z. Phillips, Heather I. Sullivan · ISLE Interdisciplinary Studies in Literature and Environment · United States

This collection of essays for ISLE assesses the material aspects of healthy economies, environments, and bodies, arguing that the traditional economic-ecological "health" dichotomy is insufficient. It finds that the determination of "healthy" is complex, as artificial environments can be benign, and even a flourishing community garden can have neglected produce going to waste. The essays explore how a large number of healthy human bodies can be detrimental to healthy environments.

Evan Weissman · Syracuse University Libraries (Syracuse University) · United States (New York City)

This dissertation explores urban agriculture in Brooklyn, New York, using a mixed-methods analysis to investigate its historical changes, motivations for engagement, and outcomes. The study argues that Brooklyn's urban agriculture is limited by its neoliberal characteristics, which undermine its potential to build a radical political movement around food issues. While urban agriculture tends to reproduce neoliberalism, it simultaneously creates political possibilities through the assertion of public rights to cultivate the city and the potential of food to serve as a tool for building solidarities towards food justice.

Danny Simatele, Tony Binns, Munacinga Simatele · Journal of Human Development and Capabilities · Zambia (Lusaka)

This field-based research in Lusaka, Zambia, examines the impact of climate change and urban governance on urban agriculture, which serves as a source of food and income for poor households amidst deteriorating economies. The study finds that urban agriculture is often excluded from urban development and planning policy, posing significant challenges for small-scale farmers to achieve food security. A lack of policies supporting the urban poor, combined with climatic changes like drought and flooding, makes it difficult for households to adapt to the changing urban environment.

Mirella Cultrera, Maria Christina de Mello Amorozo, Fábio Cop Ferreira · SITIENTIBUS série Ciências Biológicas · Brazil (Mato Grosso)

An ethnobotanical study in five peripheral neighborhoods of Santo Antônio do Leverger, Mato Grosso, Brazil, surveyed 135 households and detailed 30 to characterize food plant cultivation. Ninety-seven species from 38 families were identified across homegardens, fields, and empty lots. While some species were common, the similarity between species/varieties across households was generally below 50%, and many had low frequency, revealing a vulnerability to species loss despite social network circulation.

Monica J Kelly · Scholarship@Western (Western University) · Canada (Toronto)

An ethnographic study conducted in summer 2010 at HOPE community garden in Parkdale, Toronto, explored how collective belonging is built. The research found that differences and interpersonal conflicts within the garden were embraced as opportunities to strengthen community cohesion. Contrary to romanticized views of harmonious community gardens, the study revealed that conflicts, negotiation of differences, and institutional practices of inclusion and anti-discrimination significantly contribute to a successful and inclusive community project.

Mahbubur Meenar, Brandon Hoover · Journal of Agriculture Food Systems and Community Development · United States (Philadelphia)

This paper examines urban agriculture (UA) projects' role in addressing food insecurity in lower-income neighborhoods of post-industrial U.S. cities, using Philadelphia as a case study. While UA projects are vital, findings indicate concerns regarding their geographic, economic, and informational accessibility, social exclusion, and spatial mismatch between participants and neighborhood demographics. Challenges also exist in distributing fresh produce to impoverished populations and UA's economic contributions in underprivileged areas.

Nate Millington · International Journal of Urban and Regional Research · United States

This article analyzes representations of urban nature in Detroit, Michigan, focusing on journalistic and photographic work over the past 5 years. These representations, part of a discourse on Detroit's decline, ultimately reflect dominant conceptual divisions between the city and nature. Journalists and commentators perceive nature in the city as a reflection of the city's absence rather than its materiality, suggesting an ambivalence about emergent urban ecologies.

Robert Emmett · ISLE Interdisciplinary Studies in Literature and Environment · United States (Los Angeles)

The South Central Farm in Los Angeles, a 14-acre community garden cultivated by hundreds of residents for over a decade, was a significant site against environmental racism. However, urban development ultimately led to its destruction. As of this writing, satellite images show the former lush gardens replaced by a scraped, vacant field, highlighting the impermanence of such community-led green spaces in the face of dominant urban development narratives.

Maura Neves Coutinho, Heloísa Soares de Moura Costa · Revista Geografias · Brazil (Belo Horizonte)

This article discusses urban agriculture (UA) concepts and practices, focusing on initiatives in Belo Horizonte, Brazil, by both residents and local government. It considers UA's potential for ecological, productive, and inclusive cities, but notes the difficulty of secure access to urban land. The discussion on UA is still fragile and faces challenges in becoming an effective social policy.

Maura Neves Coutinho, Heloísa Soares de Moura Costa · Anais ENANPUR · Brazil (Belo Horizonte)

This paper discusses urban agriculture (AU) practices occurring in Belo Horizonte, Brazil, both through informal and spontaneous initiatives by residents in peripheral neighborhoods and as an object of public intervention by the local government for specific purposes. The study concludes that secure access to urban land for maintaining AU practices is difficult, and the discussion on AU remains fragile, facing challenges for its implementation as a social policy impacting urban policies.

Siny Tsang, AM Holt, Eduardo Bessa Azevedo · Chronic diseases and injuries in Canada · Canada (Cobourg, Ontario)

This needs assessment in Cobourg, Ontario, interviewed food program clients to identify barriers to food access. Clients reported lack of transportation, insufficient food quantities, and inconvenient operating hours as barriers to using food programs. They also cited lack of available vegetables and fruit at home and income as barriers to consuming more produce.

Héctor Ávila-Sánchez · Norois · Mexico

This paper discusses socio-territorial changes in peri-urban food production spaces in Central Mexico, focusing on the impacts of urbanization on old rural areas. It highlights that peri-urban poor populations often face marginalization, degradation of their agricultural activities, and conflict over space with other social groups. The development of peri-urban agriculture has led to significant transformations in land use, production structures, and social and cultural aspects.

Marcos Antonio de Castro Marques Teixeira · Aleph UCLA Undergraduate Research Journal for the Humanities and Social Sciences · Brazil

This study surveyed urban gardens in Santa Maria da Codipi and Dirceu Arcoverde, Teresina, Brazil, to assess their economic viability for gardeners. The study found that urban gardens in both areas do not provide income security for those who work them. Problems identified include petty theft, low education levels, lack of technical assistance hindering investment in new crops, and pesticide use creating a competitive disadvantage.

Michael Raleigh · eCommons (Cornell University) · United States (Buffalo)

The City of Buffalo has made progress in accepting urban farming on vacant land, but remains unwilling to take risks in this area. Policies restrict farmers' access to land, long-term security, food diversity (including animals), and sales. To foster urban farming, the City should amend these policies to grant farmers more freedom and could promote farming through a city-wide composting program and a demolition policy requiring vacant lots to be seeded with clover.
