Evan Weissman · Renewable Agriculture and Food Systems · United States (New York City)

This case study in Brooklyn, New York, used mixed qualitative research methods to investigate the political possibilities of urban agriculture for fostering food justice. Findings indicate that problematic contradictions rooted in the neoliberalization of urban agriculture limit the transformative possibilities of farming the city as currently practiced in Brooklyn. The study suggests that longstanding agrarian questions are informative for critically interrogating urban agriculture as a politicization of food.

Green Hope, River Edge, New Jersey 07661, USA., Hye Jin Keum · Journal of people, plants, and environment · United States

The philosophical background and historical development of the school garden movement in the USA were examined. The movement demonstrated a process of formation, decline, and revival. It began to diminish after World War I and was pushed to extinction by technological advancements in the 1950s, before resurging from the 1990s to address childhood obesity, nature-deficit, and improve academic achievements.

Pierrette Hondagneu‐Sotelo · Boom · United States (Los Angeles)

This article recounts the history of a central Los Angeles community garden, primarily used by women from Southern Mexico and Central America, which served as an informal support network and a place to grow culturally significant plants. The essay then details the significant upheaval that occurred after a local nonprofit took over and invested in the garden, implying a negative impact on the existing community.

A survey of Wisconsin-certified organic vegetable farmers investigated the relationships between farm characteristics, marketing strategies, and farmers' perceptions of profitability and quality of life. The data indicated that farmers selling into farmers' markets and through community-supported agriculture (CSA) were more likely to be dissatisfied with their profitability. Conversely, farmers selling into wholesale markets and restaurants/institutions were significantly more likely to be dissatisfied with their quality of life.

This study used multiple land use scenarios to assess different spaces in Montréal, including residential gardens, industrial rooftops, and vacant land, that could be allocated to vegetable production. Results indicated that implementing hydroponics on industrial rooftops could easily satisfy Montréal's vegetable demand, though these operations are generally costly. Utilizing only vacant space also has the potential to meet the city's demand with lower operating costs.

Pascale Joassart‐Marcelli, Fernando J. Bosco · Métropoles · United States (California)

This article explores the growth of local food practices in urban southern California, focusing on farmers' markets. While alternative food initiatives like farmers' markets are often seen as resistance to capitalist pressures, this research provides evidence that they have become increasingly popular among affluent and white urban residents. This finding challenges the claim that local food fosters democracy and justice, indicating that these initiatives can reproduce neoliberal urban agendas and reshape cities along lines of race and class.

Laura Oliven Silberfarb, Sonja Savre, Gayle Geber · Preventing Chronic Disease · United States (Hennepin County)

Hennepin County assessed the extent to which 41 cities were engaged in making policy, systems, and environmental (PSE) changes to increase residents' access to healthful food. Results revealed that some cities, particularly those with higher resident demand for healthful food, are making nationally recommended PSE changes, such as sponsoring farmers markets. However, cities moved more slowly to make changes in areas with perceived negative cost consequences or lesser public demand, such as parks and recreation vending.

Sarah Legg · Figshare · United States (Wyoming)

ACRES Student Farm, a University of Wyoming organization, has grown significantly over six years, providing local produce, CSA shares, composting, and educational opportunities. However, the farm suffers from continuous losses in efficiency and acquired knowledge due to the transient nature of its student management and workforce, leading to unsustainable internal functioning. This project aims to develop a management plan and handbook to address these issues and improve the farm's operational efficiency.

Nevin Cohen, Kristin Reynolds · Journal of Planning Education and Research · United States (New York City)

This article examines urban agriculture (UA) policy-making processes in New York City, focusing on aspects of UA not fully addressed by existing policies, plans, and research strategies. Interviews with UA stakeholders and an analysis of the city’s UA policy-making processes show that resource needs and race- and class-based disparities within the UA system persist.

Benjamin Drury, Renee Laliberte, Jared Watson, Connor Wilgress · Digital WPI · United States (Worcester)

The city of Worcester, MA, faces health issues due to economic instability and low access to affordable healthy food. While urban farming has the potential to address these problems, the city lacks an effective policy.

Katherine Luke · D-Scholarship@Pitt (University of Pittsburgh) · United States (Pittsburgh)

This study used a door-to-door survey in six Pittsburgh, Pennsylvania neighborhoods to measure the impact of community gardens on residents' perceptions of food access. It found that many gardeners do not consider gardening to improve their personal food security, and despite geographic proximity and expressed interest, community garden participation rates were low. Social and emotional barriers, including lack of gardening knowledge and racial prejudice, appeared to prevent residents from becoming active participants.

Matt Murray · Journal of Political Ecology · United States (New York City)

Efrat Eizenberg's book "From the Ground Up" explores New York City's community gardens as spaces that resist the commodification of land. The book details the history of these gardens, including their emergence during the 1970s economic crisis when primarily Black and Hispanic residents transformed vacant land into communal green spaces. As the real estate market recovered in the 1980s, land values increased, and many gardens were threatened by gentrification pressures. Eizenberg analyzes these transformations at individual, collective, and institutional levels, highlighting how gardeners create common spaces, solidify interpersonal ties, and organize to defend their gardens.

David R. Koenig · BIOS · United States (Sacramento)

This research project, conducted at the University of California, Davis, aims to understand how elevated soil lead levels may affect urban gardening activities in Sacramento, CA. The study investigates the distribution of soil lead levels in the city and how knowledge of this information impacts the local community. Elevated soil lead levels are identified as a potential barrier to urban gardening.

Joann Lo · Journal of Critical Thought and Praxis · United States

A first-hand essay by the executive director of the Food Chain Workers Alliance (FCWA) in the United States argues that despite growing interest in sustainable food production and systems — including community gardens, urban agriculture and "slow" food — the broader food movement has not fully integrated the voices and leadership of the workers who bring food from farm to table. It states that food workers, numbering almost 20 million in the U.S. alone, face multiple injustices including low wages, lack of benefits and dangerous working conditions that intersect with the sustainable-food movement's own concerns about food insecurity and access to healthy, affordable food, and recounts the FCWA's history and work from the author's own position.

Leandro Pessoa Lucena, Francisco José Kliemann Neto, Fernanda Mariano Massuia, Leonardo Donizete Fanti · RAI revista de administração e inovação · Canada

Against the backdrop of demographic projections that global population will reach 9.4 billion within the next 50 years, requiring an additional area of fertile land roughly the size of Brazil that does not exist on the planet, this study evaluated the economic viability of a Canadian vertical farm model as a sustainable urban-rural food production alternative. Using the NCIC method via a participant-observer approach, the study reported the model as economically viable and sustainable, as well as innovative in flattening production chains.

Ryan E. Galt · Economic Geography · United States (California)

A study of 54 Community-Supported Agriculture (CSA) farms in California's Central Valley used qualitative and quantitative data to explain farmers' earnings. An ordinary least squares regression analysis revealed that farmers' age, number of employees, and CSA type strongly influence earnings. The study found that the moral economy of CSA often results in self-exploitation due to farmers' strong sense of obligation to members, despite allowing for economic rents.

Sam E. Wortman, Sarah Taylor Lovell · Journal of Environmental Quality · United States

This review paper characterized the limited state of scientific knowledge regarding abiotic environmental factors threatening the growth of urban agriculture in the United States. It identified challenges influencing urban cropping systems, including soil contamination and remediation, atmospheric pollutants and altered climatic conditions, and water management, sources, and safety. The development of a science-based approach in these areas is noted as essential for the economic and environmental sustainability of urban agriculture.

A. Bryan Endres, Rachel Armstrong · · United States

This article discusses Community Supported Agriculture (CSA) and 'community labor,' where customers participate in food production on farms. It highlights a paradox: traditional employment law, envisioning autonomous competition, makes little room for these novel relationships, potentially undermining CSA values and limiting its viability and growth. The authors suggest that employment law should develop a more nuanced view of relationships in the CSA context, supporting mutual gain and shared values over competition-based rules.

Yuki Kato · Sociological Inquiry · United States (New Orleans)

This case study of a community-supported agriculture (CSA) organization in New Orleans focused on the lack of participation by local residents in the CSA market despite its intentions. Interview and ethnographic observation data indicated a general consensus on economic constraints, while some non-resident supporters attributed the issue to a lack of knowledge about the food system. Residents, however, pointed to spatial and sociocultural barriers, including produce selection, purchase options, market access convenience, and the race-related historical and spatial context of the market's location, making the market less accessible to them.

Larissa Vásquez-Moreno, Ana Córdova y Vázquez · International Journal of Urban Sustainable Development · Mexico (San Cristobal de Las Casas)

This study developed a conceptual framework to assess urban agriculture's (UA) potential contributions to urban sustainability (US). The framework was applied to a qualitative analysis of UA practices in San Cristobal de Las Casas, Mexico. The study found a rich practice of UA in the city and that the framework was valuable for evidencing data and stimulating analysis. However, the study also discusses limitations of UA and further refinements needed for the framework to guide actions towards increasing UA's impact on urban sustainability.

Giovania Genevieve Tiarachristie · · United States (Harrisburg)

This qualitative study explored race-class conflicts around food and urban gardening in South Allison Hill, Harrisburg, Pennsylvania, a diverse, low-income neighborhood. Seven interviews with neighborhood leaders revealed that the "Whiteness" of a new wave of urban gardening can create race and class tension, hindering collaborative partnerships and local food systems development. The findings indicate structural limitations and social roadblocks, suggesting that urban gardening can exacerbate existing inequities if not approached with structural economic justice and cultural competency.

Erika S. Jermé, Sarah Wakefield · Planning Theory & Practice · Canada (Hamilton)

This paper uses the process of drafting a community garden policy in Hamilton, Canada, as a case study. It illustrates how an environmental justice framework could inform effective and inclusive policy creation, while noting that barriers within the policy process could mitigate against the meaningful incorporation of environmental justice concerns. It concludes that greater inter-departmental and community collaboration, along with the routine application of an environmental justice lens, could mitigate the ill effects of inequitable resource distribution.

Sheila Castillo, Curtis R. Winkle, Stephen Krauss, Amalia Turkewitz, Cristina L.M. Silva, Edie Heinemann · Journal of Agriculture Food Systems and Community Development · United States (Chicago)

This study identifies seven perceived barriers to urban and peri-urban agriculture in the greater Chicago metropolitan area through interviews with urban planners and farmers. All seven barriers involve unclear or agriculture-unfriendly regulations. Results suggest that urban and peri-urban farmers are commonly forced to operate within a legal limbo or petition for exceptions to current regulations.

James R. Hollyer · PubMed Central · United States

This article discusses the potential risk of rat lungworm (Angiostrongylus cantonensis) in Hawai‘i's local food supply, which can cause eosinophilic meningitis if ingested by humans. While the statistical risk is extremely low compared to other foodborne agents, two individuals in Hawai‘i developed serious eosinophilic meningitis in late 2008 after consuming insufficiently washed local produce. The article highlights the challenge of informing the public about this rare but potentially serious disease, especially amidst efforts to promote local produce and school gardens.
