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.

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.

Camilo Villagrán Oyarzún, Ken Yan Qiu Sun · Revista de Urbanismo · Chile (Santiago de Chile)

This 2013 study investigated the challenges of integrating urban agriculture into Communal Regulatory Plans in Santiago de Chile. Analyzing two case studies in different metropolitan communes, the research inferred the general state of urban agriculture's inclusion in urban planning. The findings implicitly suggest difficulties in its integration, highlighting the need for improved governance in urban planning to effectively incorporate urban agriculture.

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.

Phil. Caleb Mireri · African Journal of Agricultural Research · Kenya (Kisumu)

This study surveyed 194 urban farmers in Kisumu municipality, Kenya, to assess urban agriculture's role in income, employment, and food supply. It found that most urban farmers and their employees receive very low income, with a mean monthly income of US$135 (US$0.64 per person per day), which is below the acceptable one dollar a day per person. Urban agriculture primarily supplements food requirements for the urban poor and provides income for a few commercial farmers.

Susana Olivares Reumont, Damarys García Céspedes, Lázaro Lima Cazorla, Israel Saborit Sánchez, Axel Llizo Casals, Pedro Pérez Álvarez · Revista Internacional de Contaminación Ambiental · Cuba (Havana)

This study investigated levels of Cu, Pb, Cd, and Zn in soils and vegetables from 17 urban agriculture farms around the "Calle 100" landfill in Havana, Cuba, during 2006-2007. Findings showed that 35% of soils exceeded typical Cuban agricultural ranges for Zn, and 52% for Pb. Critically, 23% of soils surpassed phytotoxic and international limit levels for Pb, and 12.5% of vegetable samples exceeded Cuban maximum permissible limits for Pb in food for human consumption. The results indicate a need for strict monitoring of horticultural crops in the area due to contamination.

David Adams, Alister Scott, Michael Hardman · Geografiska Annaler Series B Human Geography · Global

This article examined how planning practice, exemplified by permaculture and guerrilla gardening case studies, can be rooted in confrontation and legal challenge, hindering innovative practices. The findings confirmed that spatial planning theory is largely "disintegrated" from much contemporary planning and environmental practice and wider sustainability discourses. This suggests that planners and decision-makers' prescribed and constrained management of space can impede practices with significant societal and environmental 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.

Teferi Daba Lemma, M. S. A. Rao, M Prasada Rao · Zenith international journal of business economics and management research · Ethiopia

This study assessed the economic sustainability of urban agriculture in central Ethiopia, collecting primary data from 280 urban and peri-urban vegetable farmers. Findings indicated that urban agriculture is a viable livelihood strategy from a financial perspective. However, city administrations and policymakers pay little attention to supporting this sub-sector, suggesting that legal recognition and support would make it a more reliable strategy.

Samuel Henrique Damas Marinelo, Sandra María Fonseca da Costa, Leonardo Freire de Mello · Anais ENANPUR · Brazil (São Paulo)

In São José dos Campos, São Paulo, Brazil, residents of the Altos de Santana neighborhood maintain traditional peasant characteristics by cultivating urban gardens within a Permanent Protection Area of the Paraíba do Sul River. However, the current municipal administration plans to implement an urban park in this area, which will remove the gardens cultivated by these resident farmers. This intervention is expected to alter proposals for improving the quality of life for nearby residents concerning urban agriculture, potentially generating conflicts between stakeholders regarding land use.

Lauren M Bitter · Scholarship @ Claremont (The Claremont Colleges) · United States (California)

This autoethnographic thesis centers on the People and Their Plants garden in Upland, California, which represents the ecological changes caused by colonization in Southern California. The study critiques research and ethnography by examining the politics of knowledge, language, history, and ecology, and interrogates colonial/capitalist food systems that render Indigenous ways of knowing invisible. The People and Their Plants garden is presented as an act of resistance, creating space for alternative economic and decolonial food practices.

Maijun, Sasmito Jati Utama · Aplikasi Administrasi Media Analisa Masalah Administrasi · Indonesia (Surabaya)

This qualitative descriptive study analyzed the effectiveness of an urban farming catfish aquaculture program in Medokan Ayu Village, Rungkut District, Surabaya City. The program was concluded to be less effective overall, showing no impact on the welfare of the poor. Low understanding among participants led to cultivation failures, and the program did not achieve its goals of poverty reduction or increased income.

Lindsey Sarann Hallock · · Global

This paper examines the rise of vertical farms, arguing that they advance the corporate food regime and promote urban elite consumption. It differentiates vertical farms as local food projects that reproduce the capitalist industrial system rather than challenging it, facilitated by devalued built environments and labor surplus in neoliberal cities. The study concludes that these farms reproduce troubling trends in the corporate food regime, signifying capital's ability to standardize food cultivation and incorporate it into factory-like production systems.

Teferi Daba Lemma, M. S. A. Rao · · Ethiopia

This study assessed the social and environmental sustainability of urban and periurban agriculture (UPA) in selected towns of Ethiopia, using primary data from 280 households via questionnaires and interviews. The findings indicate that the environmental and health aspects of UPA sustainability are compromised by extensive use of chemical inputs. Furthermore, UPA is inclined to be unsustainable from a social and political perspective.

Tathagata Chatterji · South Asia Journal of South Asian Studies · India (Gurgaon)

A case study of Gurgaon, India, examined how local political factors, the rural-urban divide, and inter-governmental conflicts influenced the governance of a rapidly globalizing urban region. The study found that Gurgaon's real estate-driven transformation from a rural town to an outsourcing hub, involving the conversion of peri-urban agricultural land, has resulted in a fragmented landscape with glaring inequalities. This rapid urban makeover created everyday tensions and contradictions, particularly evident with the formation of a new municipal corporation.

Atănăsoaie George Sebastian · Annals - Economy Series · Global

Community Supported Agriculture (CSA) farms are an alternative to conventional agriculture but face numerous policy issues related to product, price, distribution, and promotion. A literature review indicated that farmers need to offer more flexible basket content in terms of quantity and product type, and consumers require information on product preparation and preservation. To offset the negative impact of high prices, measures such as cost reduction, flexible payment rescheduling, and compensation for financial resource deficits are necessary.

Adedayo A, A. M. Tunde · Sustainable Agriculture Research · Nigeria (Kwara State)

This study assessed the challenges faced by women farmers in urban areas of Kwara State, Nigeria. A total of 1,801 women farmers were sampled from different urban areas, and Focus Group Discussions were conducted. Matrix ranking revealed that lack of credit facilities was one of the most significant challenges hindering increased production by women. Other identified challenges included restricted accessibility to land and a lack of farm input.

Maxine J. Levin · Soil Horizons · United States

This commentary highlights a growing demand for soil information for green economy initiatives and climate change adaptation over the last 25 years. Despite this, USDA's funding and technical support for soil surveys in urban and nonfarm areas have been inconsistent and, in some places, nonexistent. The author argues for the vital role of modern soil surveys in addressing current needs.

WU De-hu · Anhui nongye kexue · China (Zhengzhou)

This study elaborated on the significance of developing characteristic agriculture in China's Central Economic Zone, using Zhengzhou urban agriculture as an example. It identified existing problems in urban agriculture development, including understanding deviation, extensive development, market confusion, short industrial chains, low specialization, and harsh environments. The research proposed countermeasures such as strengthening government macro-control, perfecting compensation mechanisms, and promoting scientific innovation and industrialization.

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.

Afton Halloran, Jakob Magid · Environment and Urbanization · Tanzania (Dar es Salaam)

Urban agriculture in Dar es Salaam, Tanzania, has received little political support from central and local governments over the past 30 years due to its informal status, leading to land insecurity for many urban farmers. The incorporation of urban agriculture into the Dar es Salaam 2012-2032 Master Plan (unapproved as of June 2013) and its legitimization processes were examined. It was noted that legitimization through policy could also further marginalize urban farmers cultivating open spaces within the city.

Philani Moyo · Journal of Human Ecology · Zimbabwe

This study qualitatively examined the role and contribution of urban agriculture to household food security, employment creation, and income generation among low-income working-class and urban poor households in Bulawayo townships, Zimbabwe. It was found that urban food production significantly contributes to household food access and security, improving dietary diversity and nutritional intake. However, the potential of urban agriculture is constrained by factors including land tenure insecurity, erratic water access, small plot sizes, inadequate capital for optimizing plot productivity, and ambivalent application of urban land-use laws.

Doreen Atkinson · African Journal of Range and Forage Science · South Africa

This paper critiques the assertion that commercialization of smallholder agriculture poses dangers for sustainable rangeland management in South Africa. It argues that a range of policy options are required, including commercialization and subsistence farming, large-scale and smallholder farming, various land tenure options, rural and peri-urban farming, and part-time farming. The case of municipal commonage land is used to demonstrate the effectiveness of flexible policy options regarding land ownership, farming scale, and the social nature of farming, but it is noted that effective institutional development is a key requirement in all cases.

Michael R. Hoadley · Illinois Digital Environment for Access to Learning and Scholarship (University of Illinois at Urbana-Champaign) · Global

A talk by Michael Hoadley, founder of Chicago firm Fewzion, discussed challenges in vertical farming and controlled environment agriculture. The presentation emphasized the importance of framing discussions within the context of economically self-sustainable models, free of dependence on policy subsidy and philanthropy. This highlights concerns about policymakers' over-zealous view of urban agriculture as a panacea for social ills.
