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.

This paper outlines the conception, design, and implementation process of a project aimed at strengthening technical, environmental, financial, and social capacity for urban agriculture (UA) among HIV-affected households in Nakuru, Kenya. Key lessons learned include the value of multi-stakeholder partnerships to address complex issues in urban social agriculture, the crucial role of self-help group organizations, and securing institutional commitments to support farming by HIV-affected individuals. The usefulness of mixed-methods evaluative tools for monitoring progress and identifying supports and barriers to success is also highlighted.

David Mason, Ian Knowd · Urban agriculture · Australia (Sydney)

This paper explores the history of urban agriculture (UA) in the Sydney Metropolitan Region, Australia. UA emerged as a grassroots response to global forces negatively impacting urban and farming communities, including urban sprawl, supermarket dominance, the fast food industry, and globalization in the developed world. Community-based promotion of local agriculture has led governments and organizations to recognize UA as a strategic mechanism for urban communities to address food security and other challenges.

This paper presents a Deweyan argument that school gardening prepares students for community gardening, a political activity aimed at food security, education, and community development. School gardening can also prepare children for environmental political activism, particularly involvement in gardening movements, which is presented as an interpretation of John Dewey's "civic turn" to school gardening.

This article features an interview with Christina Kaba, who works for Abalimi, an urban agriculture and environmental action association operating in socio-economically neglected townships on the Cape Flats near Cape Town, South Africa. Kaba assists individuals, groups, and community-based organizations in initiating and maintaining permanent organic food growing and nature conservation projects, which serve as a basis for sustainable lifestyles, self-help job creation, poverty alleviation, and environmental renewal.

Jonathan Crush, Bruce Frayne · Journal of Southern African Studies · Southern Africa

This article reviews urban food sources in Southern African cities, focusing on supermarket expansion, its impact on informal food suppliers, and the relative insignificance of urban agriculture for poor urban households. Findings from an eleven-city survey by AFSUN are presented, highlighting that urban agriculture has limited significance in addressing urban food insecurity in the region.

Lester Scott Lakey · BearWorks (Missouri State University) · United States (Missouri)

An ethnographic study of two farms in the Springfield Plateau region of the Missouri Ozarks was conducted to assess the effects of "local food" movements on farmers. The study found that local farms share qualities with traditional family farms. It also revealed significant variability in farmers' motivations and attitudes, ranging from farming as a means to earn family income to farming as a way to build networks connecting farmers and consumers within the community.

Kathryn A. Peters · Journal of Food Law & Policy · United States

Urban agriculture in the United States takes various forms, including individual gardens on private land, public property, and church and school grounds. Key factors for success include land acquisition, zoning ordinances, access to affordable water, infrastructure, and support services like education and outreach. Major U.S. cities, such as Seattle (declared 2010 the Year of Urban Agriculture) and Cleveland (declared 2012 the Year of Local Food), recognize urban agriculture's important role in sustainable cities and local food supply systems.

Luis Octavio Da Silva · · Global

This text presents and discusses the phenomenon of vegetable cultivation in urban environments, examining it from symbolic, utopian, and industrial era perspectives. It covers the diffusion of gardening practices, various types of urban gardens, urban self-sufficiency, and the ideology behind promotional campaigns. The article also discusses the recurring landscape practice of lawn cultivation in urban settings, including its Anglo-Saxon origins, transposition to North American urban environments, symbolism, and associated conflicts.

This study investigated the role and importance of urban agriculture in Montes Claros, MG, Brazil, as a dynamic activity creating a specific rural-urban interaction space. Using bibliographic and documentary analysis, semi-structured interviews with farmers, iconographic production, and geotechnologies for mapping, the research found that urban agriculture is a reality in intra-urban spaces. It occupies vacant lots and backyards with diverse activities, generating work, employment, income, food security, and products for local commerce.

Julian S. Yates, Jutta Gutberlet · Environment and Planning A Economy and Space · Brazil (Diadema)

This paper analyzes food waste flows in Diadema, Brazil, through an urban political ecology lens, focusing on integrated organic waste management for composting and urban food production. While presented as a means for positive socioecological change, the process is characterized by conflict and potential exploitation. Broader structural conditions also constrain the system's ability to offer an alternative to existing waste-management models.

This study investigates consumer understanding of food labeling and the marketability of authentically healthy, organic foods from independent farms. Conducted in Boulder, Colorado, it explores potential confusion between "organic" and "natural" products and reasons for participation in community supported agriculture programs. Findings suggest that a misperception between the terms "organic" and "natural" may not exist, but distinguishing them remains important.

Consuelo Montes Rojas, Astrid Alejandra Gomez · LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas) · Colombia (Popayán)

This participatory research in three communes and four urban-marginal settlements of Popayán, Colombia, surveyed 116 displaced families to evaluate chayote (Sechium edule) as a food alternative. The study found that chayote adapts well to settlement conditions and serves as an alternative food source, promoting the consumption of underutilized species and encouraging urban agriculture practices.

Ralf Otterpohl, Christopher Buzie · Waste · Global

This chapter provides an overview of biowaste management solutions, focusing on reuse. It describes high-tech systems, urine diverting flush systems, and modern dry sanitation systems like terra preta sanitation (TPS), which can produce black soil and reusable water. TPS is presented as a promising approach for managing urban household waste, addressing soil degradation and food insecurity, and potentially improving urban agriculture when combined with greywater reuse; however, questions regarding macronutrients and micronutrients remain.

Nyumbaiza Tambwe, Michael Rudolph, Ran Greenstein · Africa · Democratic Republic of Congo (Lubumbashi)

A study was conducted in Lubumbashi, Democratic Republic of Congo, from November 2004 to March 2005, on 100 farming households that adopted urban agriculture as an alternative livelihood after the collapse of a mining company. Data collected through semi-structured interviews, in-depth questions, and observation revealed that despite practicing urban agriculture, the living conditions of 75% of households declined, and 20% stabilized their living conditions but could not completely alleviate poverty. Only 5% of farmers achieved food security.

A 2011 paper from the UK discusses the Continuous Productive Urban Landscape (CPUL), a strategic concept for introducing interlinked productive landscapes into cities. It focuses on the environmental benefits of integrating urban agriculture as one of CPUL's major spatial and functional components, tracing, with reference to international exhibitions and publications, how urban agriculture has moved from a fringe interest toward the center of contemporary urban and architectural discourse. It concludes that while urban agriculture is attracting more attention, further cross-disciplinary work is needed to build the theory underpinning productive landscape design and the policy rationale to support it.

CONSUELO MONTES R, ASTRID ALEJANDRA GÓMEZ G · DOAJ (DOAJ: Directory of Open Access Journals) · Colombia

This participatory study evaluated Sechium edule (chayote, locally "cidra papa") as an alternative food source for displaced families living in marginal urban settlements of Popayan, Colombia, aiming to recover traditional knowledge of its use and management, identify ecotypes, capture its sociocultural significance as a means of maintaining ties to the countryside, and assess its productivity and management potential in marginal urban spaces. Using participatory methods including recreational activities, awareness workshops, and knowledge- and seed-exchange tours, the study covered three communes in Popayan, applied 116 surveys across four selected settlements, and conducted monthly visits with informal dialogue with participating families. It confirmed that plants such as chayote adapt to conditions in the settlements and can serve as an alternative food source for these populations, and the activities encouraged consumption of underutilized species, knowledge exchange, and conservation of ecotypes and plant species able to withstand marginal conditions.

Samuel W. Lewis · Scholarship @ Claremont (The Claremont Colleges) · United States (California)

In summer 2010, 11 high school students from under-resourced communities in Pomona, Montclair, La Puente, and Chino Hills, California, were paid to participate for six weeks (five days a week, 30 hours a week) in the Youth Earth Connections (YEC) summer internship program, funded by the 2010 Davis Projects for Peace and a Pomona College Summer Undergraduate Research Project Award. The program was designed to connect movements for food and environmental justice with farming work, and weekly survey responses from interns suggest that experiential urban farming programs at the high school level can connect students with issues of environmentalism and social justice and motivate action against the industrial food system and the environmental injustices they experience.

Edna Bonacich, Jake Alimahomed‐Wilson · Souls · United States (California)

The role of capitalism in the ecological crisis and jobs crisis facing the Los Angeles African American community is examined, arguing that sectors of Black Americans, like many people in the Global South, are being pushed out of the formal system of capitalist employment. In response, the paper looks to delinking and the development of economic experiments rooted in community economic self-determination based on anti-capitalist values, reporting on a small urban farming project the authors are starting.

杨海云, 勾通 · 中国农村金融 · China

This 2011 article profiles a rural credit cooperative in Fucheng District, Mianyang, Sichuan Province, China, located at the urban-rural fringe in an area experiencing rapid urban-rural integration. Amid the Chinese Communist Party central government's Document No. 1 policy focus on rural issues, and as three rural issues (agriculture, rural areas and farmers) and agricultural industrialization advanced, central and regulatory bodies adjusted requirements and policies for financial institutions supporting these areas. The Fucheng District Rural Credit Cooperative, following the principle of supporting local economic development and aligning with local agricultural industrialization projects and structural adjustment plans, seized these policy opportunities and served as a leading force in agricultural support, achieving three shifts — including a shift from supporting rural village agriculture toward supporting urban, suburban and export-oriented agriculture.

Ruth Beilin, Ashlea Hunter · Local Environment · Australia

In Australia, a 2011 study developed a set of social and ecological indicators aligned with local government policy areas and accountability frameworks through a participatory process involving local government officers, community garden (CG) members and industry experts. Since Agenda 21, local governments have sought ways to engage urban citizens in building more sustainable cities, and community garden activities are frequently described as contributing to socially and environmentally sustainable local communities, yet a suitable set of indicators for valuing these benefits had not previously been established. The indicators were designed so individuals could use and learn from them, contributing to policy decisions and being meaningful to urban planners and local gardeners. The study demonstrates the practical necessity of devising indicators that CG participants can realistically monitor and that hold political and ideological value for local governments and wider community stakeholders.

Andrew Kimbrell · Tikkun · United States

This essay criticizes the dominant industrial food model, corporations turning agriculture into agribusiness through heavy chemical, mechanical and genetically altered inputs, as producing profound alienation between the public and food production; it argues that increasing urbanization widens this physical and psychological distance, obscuring the industrial food model's consequences, including forest destruction, animal cruelty, pesticide harm to farmworkers and wildlife, and devastation of farm communities, which together constitute a moral crisis as well as an environmental and health crisis. It also describes a growing organic-and-beyond movement over the past two generations, with millions of Americans joining community supported agriculture (CSA) and opposing pesticide misuse, factory farming and genetic engineering of crops.

This paper evaluates the sustainability of the Market Basket (MB), a modified Community Supported Agriculture program run by Post Oil Solutions in Brattleboro, Vermont, USA, that provided local, fresh vegetables to low-income consumers at wholesale prices across two locations over two years, drawing on the author's experience as market coordinator, focus groups, interviews, and secondary data. Over 60 people participated in the MB during that period, and the paper argues the MB was an effective approach for increasing produce consumption, but issues affecting its sustainability remained unresolved — most notably funding to support a coordinator and increasing participation among generationally low-income consumers — with steps to address both currently underway.

This review examines evidence that intensive use of pesticides, chemical fertilizers, hormones, antibiotics, and fossil fuel in the US food production system, along with chemicals in food packaging, are potentially harmful to human reproductive and developmental health, and argues that policies including changes to the Farm Bill and the Toxic Substances Control Act, plus greater health-sector involvement in sourcing food from urban agriculture programs and farmers, are needed to prevent adverse reproductive effects. The abstract does not report a specific negative or null finding about urban agriculture itself — urban agriculture programs are named only as one proposed sourcing channel within the recommended policy response, not as a subject with measured outcomes.

In Cape Town's high-rise neighborhoods, South Africa, where geographic constraints and socio-economic disparities limit access to fresh produce, a mixed-methods study using surveys, interviews and observation compared participants who regularly used community garden spaces with a control group who did not. Community gardens yielded an average of 50% more fresh produce per square meter than traditional urban plots, contributing to local food security, and garden users showed health changes including better nutrition and lower obesity rates.
