A study in Alexander First Nation, central Alberta, Canada, used asset mapping with children to understand how community factors shape the lifestyle behaviors of First Nations children living on reserve, who are estimated to be 4.5 times more likely to be obese than Canadian children generally. Participants were a convenience sample of two high school students working at the local health centre and seven grade six children, who used maps, photographs and a town tour to identify 25 activity- or food-related places and spaces. Breakfast, lunch and snack foods (such as chocolate bars and potato crisps) were obtained at school, food and snacks at cultural gatherings, and snacks at the local store, with healthy food choices found to be limited; only two locations beyond the town site were identified for physical activity, and youth recommended building a leisure centre, selling healthier food at the local store, and developing a community garden and berry farm.

In Santa Clara County (SCC), located at the southern end of the San Francisco Bay Region and marked by high income disparities and an ethnically diverse population, this study used surveys and Geographic Information Systems (GIS) to examine links between the presence and use of school gardens and the socioeconomic and ethnic composition of surrounding neighborhoods. Statistical analysis found that school gardens in SCC are more likely to exist in economically stronger and ethnically less-diverse neighborhoods, showing that garden provision is not equitably distributed. School gardens can be maintained with relatively modest resources — a coordinator, planting area, small budget, and school-community support — yet securing these resources can itself be a significant barrier for some schools. Because natural play areas suited to environmental exploration were not typically found at SCC schools, the study suggests school gardens can play an important role in reconnecting children with the natural world.

This is a systematic review protocol — not a completed review — that sets out methods for identifying, appraising and synthesizing evidence on how urban agriculture programs affect food security and nutrition in low- and middle-income countries. It notes urban agriculture is widely promoted as providing the urban poor with food and income while improving the urban environment, but also carries potential disadvantages: use of wastewater can contaminate produce, intensive irrigation can spread malaria and water-borne disease and strain limited water supplies, and soil erosion and intensive fertilizer/pesticide use can pose health risks and environmental damage. Despite the current policy drive to promote urban agriculture, the paper states that the evidence base for its benefits and harms is not well understood. As a protocol, it reports planned search, screening, bias-appraisal and synthesis methods rather than results.

This study, conducted from July 2007 to July 2008 at the Urban Agriculture Demonstration Site in La Paz, Iloilo City, evaluated soil media and ameliorants for container-grown green onion, pechay, and tomato. Pure compost was found to be the best medium for increasing yields. However, the use of IMO and rice hull as soil ameliorants did not increase yields for the three tested vegetables, and rice hull generally reduced pechay yields.

Martijn Koster, Pieter A. de Vries · Focaal · Brazil (Recife)

This article examined slum dwellers' politics in Recife, Brazil, as a realm of possibility where care and recognition are central. A community leader's urban agriculture project, which from an outsider's perspective might be considered non-viable, provided slum dwellers with possibilities to strive for community solidarity and personal recognition. The article concludes that slum politics is about claiming the right to be counted and recognized, and about the care for the other.

This field-based research in Lusaka, Zambia, examines the impact of climate change and urban governance on urban agriculture, which serves as a source of food and income for poor households amidst deteriorating economies. The study finds that urban agriculture is often excluded from urban development and planning policy, posing significant challenges for small-scale farmers to achieve food security. A lack of policies supporting the urban poor, combined with climatic changes like drought and flooding, makes it difficult for households to adapt to the changing urban environment.

A study on food security in Msunduzi Municipality, South Africa, was part of AFSUN's baseline survey across eleven Southern African cities. The survey found that urban poor in Msunduzi are significantly worse off than those in Cape Town and Johannesburg, with one-third of households reporting frequent food shortages. Urban agriculture is not particularly significant in Msunduzi, and while supermarket supply chains dominate the food system, they do not meet the needs of the poor.

Jonathan Crush, Bruce Frayne, Wade Pendleton · Journal of Hunger & Environmental Nutrition · Sub-Saharan Africa

A paper on rapid urbanization and rising urban poverty shifting the historical locus of food insecurity from rural areas to the cities of Africa uses baseline survey data from the African Food Security Urban Network (AFSUN), carried out in 11 cities in 9 southern African countries in 2008-2009, to demonstrate extremely high levels of urban food insecurity. It finds that lack of access to food results primarily from household poverty, high unemployment, and limited income-generating opportunities rather than any absolute food shortages. The paper also shows the growing importance of supermarkets, and finds that urban agriculture plays a relatively insignificant role in the food sourcing strategies of the urban poor.

A study surveyed 700 randomly selected households across Kano (Nigeria), Bobo Dioulasso (Burkina Faso), and Sikasso (Mali) to explore the relationship between household socioeconomic status (SES) and participation in urban and peri-urban agriculture (UPA). The results showed no significant differences in UPA participation rates across socioeconomic groups. Instead, UPA participation was significantly and positively related to household size.

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.

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.

This needs assessment in Cobourg, Ontario, interviewed food program clients to identify barriers to food access. Clients reported lack of transportation, insufficient food quantities, and inconvenient operating hours as barriers to using food programs. They also cited lack of available vegetables and fruit at home and income as barriers to consuming more produce.

Jonathan Crush, Alice J. Hovorka, Daniel Tevera · Progress in Development Studies · Africa

This article examines the contemporary importance of household food production in poor urban communities across 11 Southern African Development Community (SADC) cities. It finds that urban food production is not particularly significant in most communities, with many more households relying on supermarkets and the informal sector for food access. Furthermore, few households derive income from selling produce, though the situation varies considerably by city.

Urban agriculture in Kinshasa, Democratic Republic of Congo, serves as a palliative solution for social survival constraints such as a lack of remunerative salaries and sustainable jobs. However, poorly supervised urban farmers cultivate along busy roads, exposing vegetables to various contaminations, including lead. This practice highlights issues with site selection and supervision.

A literature review examined the use of school garden programs for health promotion among elementary school youth. The review found that school gardens successfully improved academic achievement, increased fruit and vegetable consumption, and enhanced social skills. However, significant barriers to implementation were identified, particularly in low socioeconomic status schools, including a lack of funding, insufficient gardening knowledge among teachers, and limited community and parent involvement.

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.

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.

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.

Tommy Bleasdale, Carolyn J. Crouch, Sharon L. Harlan · Journal of Agriculture Food Systems and Community Development · United States

Researchers studied a struggling community gardening program in a low-income minority neighborhood in Phoenix, Arizona, operated within a larger local food initiative led by a nonprofit community development organization. Based on interviews and participant observation used to build an exploratory survey, the study found that while residents had gardening interest and experience, awareness of the program itself was low, perceptions of gardening's benefits and burdens varied among current gardeners, ex-gardeners, and those who had never gardened, and the benefits residents cited often differed from the goals stated by the local food initiative.

Morongoa Rosina Pako · · South Africa

This qualitative study assesses the Mogabane Community Garden Project in South Africa to determine why it did not reach its objective of poverty reduction in the community. It situates the project against South Africa's poverty lines — roughly 33% of the population living on less than R271/month, 50% on less than R422/month, and 79.1% on less than R1,230/month, with the highest poverty rates in the Eastern Cape (68.3%) and Limpopo (60.7%) provinces and the lowest in the Western Cape (20%) and Gauteng (28.8%) — and the government's post-1994 anti-poverty programs spanning social assistance, employment generation, enterprise development, basic household security, social services, disaster relief, and employment-related social insurance. Against this backdrop, the study assessed the Mogabane project and confirmed that it failed to achieve its poverty-reduction objective.

Geoffrey Ross Owens · Africa · Tanzania (Dar es Salaam)

This article, using ethnographic and historical approaches, examines unplanned peri-urban settlements on Dar es Salaam's northern and western fringe, Tanzania, between 1975 and 2000. These districts were established by educated urban professionals who used urban farming as an economic diversification strategy. The study found that these settlements contributed to the reproduction of socio-economic inequality, attracting additional economically influential urban in-migrants after 1991.

M. Tshitangoni, A. Okorie, Joseph Francis · Scientific Research and Essays · South Africa (Limpopo Province)

A study conducted in Vhembe District, Limpopo Province, South Africa, assessed challenges faced by 30 poverty alleviation projects (community gardens, poultry, etc.). A survey of 108 beneficiaries identified numerous inception-based challenges, such as lack of training (90%), lack of funds (80%), and fraudulent use of funds (33%), as well as operation-based challenges like poor record keeping (70%) and unavailability of markets (60%). These challenges were found to significantly limit the performance of the poverty alleviation projects.

A survey was conducted in almost all primary and secondary schools in Nakuru Town, Kenya, to examine the extent to which school farming contributes to school feeding programs. The survey found that while school farming and feeding programs are common practice, school farming substantially contributes to school feeding programs in relatively few cases.

This paper analyzed the impact of armed conflicts on urban livestock keeping, particularly small ruminant keeping, in Brazzaville, Republic of Congo. Two surveys, one before 1993 and one after 2002, indicated that the 1997 conflict had a negative impact on livestock keeping, as most livestock keepers lost their animals. Financial resources were an important factor in rebuilding the flock after 1997.

Alec Thornton, Etienne Nel, Godfrey Hampwaye · Development Southern Africa · Zambia

A review of urban agriculture in Zambia's four largest cities revealed that despite attempts by the Kaunda government in the 1960s–1970s to create supportive policies, there is currently a near absence of institutional support, constraining farmers' activities. A survey of 400 farmers confirmed the value of urban agriculture as a survival strategy but also highlighted the lack of necessary support measures.
