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.

Vanna Gonzales, Nigel Forrest, Noreen Balos · Journal of Community Positive Practices · United States (Arizona)

This paper presents the first known case study of Gila Farm Cooperative (GFC), a U.S.-based marketing cooperative formed by refugees from different ethnic and cultural backgrounds. Founded in 2011 by the Phoenix International Refugee Committee, GFC has 22 members supporting Community Supported Agriculture in central Arizona. This three-month study, conducted in spring 2012, provided a descriptive analysis of GFC's structure and operational processes through participatory observation and in-depth interviews.

Javier Morales, Ramón Zamorano, Miguel Salvo · RURAL DEVELOPMENT 2019 · Peru (Lima)

This study showed the situation of urban agriculture five years after the "Farmers in the city" project, carried out by the International Potato Center (CIP) and GESPLAN research group in the East Cone of Lima, Peru, from 2006 to 2008. All members of the Cosanaca producer association, created under the project, were interviewed, and an expert panel was conducted with municipal urban agricultural office representatives. The results showed that Cosanaca had doubled its number of producers and that the participating municipalities had increased their number of workers in urban agriculture.

Kenrett Y. Jefferson-Moore, Richard Robbins, Daniel L. Johnson, Jefferson-Moore, Kenrett Y., Robbins, Richard D., Johnson, Daniel · AgEcon Search (University of Minnesota, USA) · United States (North Carolina)

This study evaluated consumer perceptions of organic and locally grown produce at farmers' markets in North Carolina, focusing on the Piedmont Triad region. Using qualitative methods with focus groups from five locations, preliminary findings showed consumers distinguish local and organic foods only by labeling. Participants had limited knowledge of organic certification, and while most purchased more local foods, they were willing to pay up to 100% more for organic food.

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.

Kelsey Hall, Courtney Meyers, David L. Doerfert, Cindy Akers, Phillip Johnson · Journal of Applied Communications · United States (Texas)

This mixed-methods study explored how Texas CSA shareholders received local food information and how CSA owners recruited and retained members, given retention rates of 20-70% nationwide. Data from an online survey of three Texas CSAs and interviews with owners showed shareholders preferred daily/weekly information searches via websites and interpersonal communication. Owners used local media, events, and word-of-mouth for recruitment, and weekly email newsletters for retention.

Kathryn Colasanti, Michael W. Hamm · Journal of Agriculture Food Systems and Community Development · United States

This paper criticizes Hallsworth and Wong (2013) for failing to adequately recognize the potential for increased productivity in urban agriculture and its role in alleviating food insecurity. The authors emphasize the opportunities for urban agriculture in diverse North American cities and the potential for productivity expansion using methods like passive solar and season extension. They cite examples such as Michigan hoophouses growing 30 crops year-round and a 4-square-meter garden providing daily vegetable servings for a family of four, arguing that urban agriculture's value extends beyond food quantity.

Susanne A. Heckler · ValpoScholar (Valparaiso University) · United States

This paper examines the "shrinking city" phenomenon in American cities, characterized by rapid population decline and increased vacant properties, and explores urban agriculture as a strategy to address this issue. It discusses the benefits and drawbacks of urban farming, the historical impact of American zoning and nuisance laws on agriculture, and current efforts to integrate urban agriculture into state and city policy frameworks.

E. N. Ward · SMARTech Repository (Georgia Institute of Technology) · United States

This paper aimed to assert that urban agriculture provides economic and environmental benefits to cities, specifically identifying ways the City of Atlanta could leverage these benefits. It tested the hypothesis that Atlanta can economically benefit by establishing urban agriculture as a land use, using a literature review, scaling data from other cities to Atlanta, and land suitability analysis. The analysis indicated that urban agriculture offers advantages in waste management, public land management, and stormwater management, demonstrating it as an economically viable movement providing social, environmental, and economic benefits.

Evan Weissman · Journal of Agriculture Food Systems and Community Development · United States (New York City)

This essay refutes the claims by Hallsworth and Wong (2013) that the benefits of urban food gardening are exaggerated and that it cannot deliver fresher or lower-cost foods. It states that Hallsworth and Wong's assumptions are incorrect and that urban gardening plays a significant role as public space, an economic development strategy, and a community-organizing tool, contributing to household food security. For example, a 0.2-hectare urban farm project in Brooklyn, New York, "East New York Farms!", produces over USD20,000 of fresh produce annually, with over 70% of transactions made through SNAP, reaching high-need community members.

Camila Tavares Ferreira, Silvia Coelho do Nascimento, Marlene Evangelista Vieira, R. F. de M. Tavares, Lucélia Rosa de Jesus · Cadernos de Agroecologia · Brazil (Marituba)

This study evaluated the socioeconomic aspects of agriculture in the Uriboca community of Marituba, Pará, Brazil, by applying questionnaires to 13 local producers. The main commercial products were foliage, medicinal plants, and flowers, sold primarily in Belém and Marituba, while cassava, beans, and small animals were produced for consumption. Most producers had production costs between R$250.00 and R$500.00, with variable net incomes mostly ranging from R$250.00 to R$500.00 and R$500.00 to R$1000.00. Leafy greens were the main commercialized crops due to their ease of adaptation, management, and demand.

Charles E. Hess · HortScience · United States

Reflecting on horticultural science over the past 60 years, it is evident that it is in a period of great opportunity. Recognition of the role of fruits and vegetables in a healthful diet has led to food for health initiatives that encourage diets rich in horticultural crops. The 'locavore movement' fosters the popularity of purchasing locally, spurring increased interest in farmers' markets and urban gardening. Internationally, the idea of peri-urban gardening recognizes the value of horticultural crops in improving nutrition and income on relatively small areas of land in developing nations.

Leslie Gray, Patricia Guzmán, K. Michelle Glowa, Ann Drevno · Local Environment · United States (California)

This article examines La Mesa Verde, a home-gardening program in San Jose, California, to assess if home gardens offer similar financial, health, and community benefits as community gardens. The research explores the potential of home gardens to foster broader social change, cultural preservation, and self-determination, especially for recent immigrants.

José Luis Yagüe Blanco, Agustín Montes, Francisco J. Morales · · Peru (Lima)

This article examines the evaluation of an urban agriculture project in the outskirts of Lima, Peru, using a process-centered approach. The results show that this approach, which combines different evaluation tools, allows for the identification and analysis of processes with involved members, providing a better understanding of the real sustainability of the results.

Freda G. Sampson, Thomas G. Costello, Stacey Stevens, Desiree Squire · Journal of Law and Society · United States (Detroit)

This paper examines Detroit, United States, as a city in crisis, analyzing redevelopment conflicts between gentrification and revitalization. It applies a "Litmus Test for Equity and Opportunity" to current redevelopment efforts, including the Detroit Future City Plan and projects by Michael Ilitch & Company and Dan Gilbert. The analysis suggests that despite efforts, the complexities of this post-industrial city, particularly regarding its predominantly African-American population, are only superficially addressed, indicating ongoing equity challenges.

Leah A. Walker · · United States (Detroit)

This comment discusses the history, benefits, and laws relevant to urban farming in the United States, with a specific focus on Detroit. It highlights the essential role of urban agriculture for Detroit's survival and potential revival. The comment also examines the laws with the most immediate impact on urban farming in Detroit and the significance of timing due to impending changes in zoning ordinances.

Amanda Jessie Weaver · Digital Commons - DU (University of Denver) · United States (Colorado)

This project combined U.S. Agricultural Census data with a survey of local producers in Colorado's Front Range Urban Corridor to examine the competition between urban development and food production. The study found that urban development is increasingly encroaching on rich agricultural lands, which are also desirable for housing. Consequently, Colorado faces increasing competition for land, potentially driving local food prices up and displacing producers to peripheral areas or out of food production entirely.

Glenda Dimuro, Esteban de Manuel Jeréz · POLI-RED (Revistas Digitales Politécnicas) (La Universidad Politécnica de Madrid) · Brazil (São Paulo)

This paper presents the 'Cidades sem fome' project, a citizen initiative in São Paulo's degraded areas. Through urban agriculture, this project enables residents to satisfy basic needs, regain control over their lives, and challenge market-driven growth processes. It aims to reduce hunger and unemployment, foster social mobilization, and rehabilitate degraded urban areas, offering an alternative to current urban production and management models.

Brandi Janssen · Anthropology of Work Review · United States

This paper explores labor strategies for producers in the growing local food sector, where increased demand creates challenges for scaling operations. A major obstacle to growth is access to reliable, affordable labor. The paper discusses typical options for obtaining and retaining labor, including paid employees, volunteers, and interns, noting that each strategy has social and economic advantages and disadvantages for producers and the community.

Laura Lavid · Journal of Agriculture Food Systems and Community Development · United States

This article discusses the impact of urban gardening on a city's food system, noting that while it is not the sole solution, it offers significant benefits beyond economics. It cites historical data from World War II, where 20 million victory gardeners produced 44% of fresh vegetables in the United States. Recent studies estimate community gardens can yield $500 to $2,000 worth of produce per family annually, and a Denver study found community gardeners ate significantly more fruits and vegetables than non-gardeners.

Bruno Henrique Comassetto, Gabriela P. Solalinde Z., João Vicente Rosa de Souza, Marcelo Trevisan, Paulo Ricardo Zilio Abdala, Carlos Alberto Vargas Rossi · Revista de Administração de Empresas · Brazil

A qualitative study with in-depth interviews of urban agriculture specialists and practitioners in nine neighborhoods of a large Brazilian capital explored the meaning of urban agriculture as a consumption phenomenon. The findings indicate a dual motivation for practicing urban agriculture: an extrinsic motivation (example) and an intrinsic motivation (well-being). The practice is linked to concerns for the environment, health, and personal well-being, as well as nostalgic respect and pride for cultural heritage.

Marcos José de Abreu, Renato Barretto Barbosa Trivella, Letícia Oliveira de Melo, gisa Garcia, Alexandre Cordeiro, Óscar José Rover · · Brazil (Santa Catarina)

The Vida Nova community garden, established in 2009 in Jardim Janaina, Biguaçu, Santa Catarina, Brazil, serves women from rural and urban areas facing food and social insecurity. This project aimed to disseminate participatory agroecological methodologies in urban agriculture. It resulted in a 36-page educational booklet and a course, leading to group strengthening, increased community gardens, and diversified cultivation in the neighborhood.

Nicholas F. Reed · Stanford law & policy review · United States (California)

This legal note centers on California Assembly Bill 551 (AB 551), introduced on February 20, 2013 by Assemblyman Phil Ting, which would create incentives for owners of undeveloped urban residential property to lease their land for agricultural use or the creation of urban green space. It positions AB 551 as a potential "Williamson Act for cities," in contrast to the 1965 California Land Conservation Act (the Williamson Act), which was intended to protect rural agricultural land from urban development; AB 551 would instead let local governments encourage commercial agriculture where urban development is infeasible or has stalled. The author reviews the social, economic, and environmental benefits attributed to urban agriculture, legal barriers such as property tax and zoning codes, and the history of differential tax programs protecting agricultural land, before explaining the rationale for the AB 551 proposal.
