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.

A. Yusuf · · Nigeria (Lagos State)

This study assessed the attitudes of 50 women farmers towards urban agriculture in the Somolu local government area of Lagos State, Nigeria. Findings indicated that the women's attitude towards urban agriculture was extremely negative. Statistical analysis revealed a significant relationship between attitude and age, marital status, educational level, years of experience, and access to loans. However, farm size, annual income, access to labor, and access to inputs were statistically insignificant.

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.

Rabiul Islam, Chamhuri Siwar · Advances in Environmental Biology · Malaysia

This research analyzed the current situation and future potential of urban agriculture in Malaysia using a literature review. Study participants demonstrated a relatively greater awareness of environmental and community benefits of urban agriculture compared to food security, health, or economic benefits. Malaysian urban agriculture was found to be constrained by a lack of adequate land use planning, weak support for urban farmers, and an absence of an integrated development approach. Major challenges identified included perceptions of limited space, limited resources, and education.

This abstract is an article on the challenges and prospects of urban agriculture, published in the journal Urban Environment via the Érudit platform. This abstract does not contain detailed content regarding specific challenges or prospects related to urban agriculture governance.

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.

Iwona Makuch · Soil Science Annual · Global

This study investigated the influence of intensive horticulture on lead content and its fractions in soil profiles from house gardens, allotment gardens, and arable fields. It was not determined that the manner of usage had any influence on total lead content or its distribution in soil profiles. However, the usage manner did influence the content and distribution of lead fraction III, which is connected with organic matter, with humus horizons of garden soils showing the highest content.

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.

Vide Adedayo · · Nigeria

A study of poultry waste management and utilization techniques in urban vegetable farms in metropolitan Lagos revealed that poultry waste is poorly collected, packaged, and transported. Proper knowledge on treatment is lacking due to insufficient skill, space, time, and capital. Furthermore, a significant difference was found between poultry waste utilization, crop yield, and revenue in the study area.

Richard Wiltshire, Louise Geoghegan · Research Portal (King's College London) · United Kingdom

This chapter explores the social organization of voluntary urban food production in Britain, identifying two dominant modes: collective activities and individual allotment gardens. It notes that the organization of unpaid labor is an under-researched aspect and a key restraint on urban agriculture's expansion. The study found that relations between these two modes can be antagonistic, particularly when land is scarce.

This study investigated the presence of zoonotic agents in small ruminants kept on city farms in southern Germany, sampling feces and nasal liquid from 48 animals (28 goats, 20 sheep) across 7 city farms and one activity playground. Findings revealed that 100% of sampled sheep and 89.3% of goats carried Shiga toxin-producing Escherichia coli (STEC). Staphylococcus spp. were detected in 75% of both sheep and goats, and Campylobacter spp. in 25% of sheep and 14.3% of goats. Neither Salmonella spp. nor Coxiella burnetii was found.

Huang Xue-qun · · China (Tianjin)

This paper analyzed the development status of Tianjin urban fishery, finding it to be in an early stage. Problems identified included a low level of industrial development, an unscientific development mode, and weak innovation capability. The study proposed development paths and measures for industrial transformation and upgrading.

Batanai L Sammie, Charles Nyamutowa, Munyaradzi Gwazane · International Journal of Scientific Research · Zimbabwe

This study used FGDs and case studies to identify perceived causes of failure of NGO urban agriculture initiatives in Zimbabwe. The study identified the principal-agent relationship between NNGOs and LNGOs as the epicenter of all initiative failures.

John Jacob, Samuel E. Kakulu · American Journal of Chemistry · Nigeria

Soil and vegetable samples (spinach, jute mallow, and tomato) were collected from farms and gardens across 20 zones within Kaduna, Nigeria, plus two rural control villages about 30 km from the city, and analyzed for heavy metals by Flame Atomic Absorption Spectrophotometer. Pollution Load Index results showed soils in the city farms were moderately enriched with cadmium and chromium and strongly enriched with lead and nickel from anthropogenic sources. Mean soil concentrations of lead and cadmium exceeded WHO/FAO permissive limits for agricultural soil (nickel and chromium did not), while vegetable metal concentrations exceeded the permissive limits for every metal except nickel — a finding flagged as concerning given the toxicity of lead and cadmium in particular, which have no known biological use.

André Viljoen, Katrin Bohn · Architectural Design · Global

This piece by André Viljoen and Katrin Bohn of Bohn&Viljoen Architects juxtaposes the organopónicos, or market gardens, of Cuba — which proliferated after the US trade blockade of the 1990s and the resulting fuel shortages — with more recent food-production experiments in North American cities that draw on the Cuban example. The authors argue that in urban agriculture there is a direct connection between scarcity and abundance, with the threat of food shortages repeatedly acting as an effective trigger for food-growing enterprises, and that produce can be grown even with few or limited resources.

Les Levidow, Katerina Psarikidou · · United Kingdom

In Manchester, England, environmental and health issues have been folded into a wider agro-food strategy aimed at making the city "more sustainable." With support from state bodies and charities, several initiatives have expanded access to fresh, healthy food, particularly in "food deserts," mobilizing resources, skills, and voluntary labor through "community engagement" to create "community spaces" for social inclusion. Manchester's agro-food networks shorten supply chains by linking peri-urban agriculture more directly with urban consumers and by promoting urban agriculture grounded in local resource mobilization and personal trust, offering an alternative to conventional agro-food chains; food relocalisation is described as helping overcome socio-economic inequalities and health problems, with Manchester initiatives cooperating to build environmentally sustainable, socially just, healthy communities and reconstructing local identities and social commitments, within a national policy context that advocates food relocalisation but provides little actual support. Despite that activity, the larger food system in Manchester remains dominated by conventional agro-food chains, and community food initiatives play only a marginal role, leading practitioners to discuss how to overcome these limitations; from 2010 onward, the UK government's austerity regime is described as undermining state support further, making community engagement even more important for mobilizing resources.

R. Plant, Jeremy Walker, Scott Rayburg, J Gothe, Teresa Leung · Australian Geographer · Australia

A study of the Hawkesbury-Nepean River in Sydney, Australia, examines the effects of pesticide use by the small-scale horticulturalists supplying the city's fresh vegetable markets on aquatic biodiversity. Through interviews with actors across the institutions responsible for agriculture, water quality, and environmental protection, it assesses the effectiveness of pesticide governance in the Greater Sydney Basin. It finds that pesticide pollution is rarely measured or monitored and is not a priority for any particular agency, meaning the pollution remains effectively uncontrolled. The study concludes that although public health, the long-term viability of local farming, and the ecological health of the river are compatible goals, they currently exist under a system of "organised irresponsibility."

Simon Mariwah, Jan-Olof Drangert · Waste Management & Research The Journal for a Sustainable Circular Economy · Ghana

A study in a peri-urban agricultural community in Ghana explored attitudes towards sanitized human excreta as fertilizer, collecting data from 154 households. It found a general negative attitude towards fresh excreta and its handling. While residents accepted excreta could be used as fertilizer, they were unwilling to use it on their own crops or consume such fertilized crops.

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.

Stephen Odede. Shisanya, Sheryl L. Hendriks · Development Southern Africa · South Africa

This study evaluated the contribution of community gardens to alleviating food insecurity for 53 community gardeners in Maphephetheni, KwaZulu-Natal, South Africa. Using the Household Food Insecurity Access Scale, it was found that 89% of these households were anxious about food supplies, consumed insufficient food, and were severely food insecure. Additionally, 72% consumed poor quality food. Community gardens were unable to solve the problem of food insecurity, but their contribution to consumption cannot be entirely ignored.

M. Tshitangoni, A. Okorie, Joseph Francis · Scientific Research and Essays · South Africa

In Vhembe District, Limpopo Province, South Africa, the performance of 30 poverty alleviation projects (12 community gardens, 8 poultry, 2 piggery, 2 bakery, 6 other) was reviewed. Based on structured questionnaires with 108 respondents, project performance differed by type. All bakery projects were successful, poultry projects achieved 62% success, and community garden and other projects each achieved 33% success. In contrast, all piggery projects performed poorly.

A. K. Ango, Aliyu Abdullahi, Bello Bunza Abubakar · International Research Journal of Agriculture and Soil Science · Nigeria (Birnin Kebbi)

A study in Birnin Kebbi metropolis, Nigeria, during the 2009/2010 cropping season surveyed 100 urban farmers across 10 districts. The study found that urban farmers cultivate food crops and rear animals, but identified low capital, lack of adequate funds, strict land-use regulations, and lack of agricultural inputs as major problems. Socio-economic status, family size, and education level were significantly related to participation in urban farming.

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.
