A study in Ibadan, Nigeria, reviewed grasscutter rearing as an urban agricultural practice. It found that farmers used intensive rearing systems and sold animals for N1,000-N2,100, generating up to N5,000 annually per pair. However, the provision of credit was identified as a major limiting factor for this practice.

This mixed-methods study investigated urban youth engagement in community gardening initiatives in six South African cities, using surveys, ethnographic observations, structured interviews, focus groups, and participant observation. Participants reported a significant 34% increase in self-reported empowerment levels after engaging in these initiatives. The findings suggest community gardens can be effective for youth empowerment, but further research on long-term effects and scalability is needed.

To evaluate the impact of community gardening on urban nutrition security in Cape Town slums, a mixed-methods study was conducted over two years. Data collected through surveys and interviews revealed a statistically significant increase in dietary diversity (p < 0.05) among community gardeners compared to a control group. This study confirmed the positive impact of community gardening on urban nutrition security and diet quality in Cape Town slums.

E. Albertse, Technikon Pretoria · · South Africa (Atteridgeville)

This article identifies and defines three extension domains among urban farmers in the informal settlements of Atteridgeville, South Africa: home gardeners, community-project gardeners, and users of open urban spaces. A survey (n=120) with face-to-face interviews, structured interview schedules, semi-structured interviews, and observations gathered information on farming space, crops, resources, and socio-economic characteristics. The study concludes by calling for greater government and public extension involvement in urban agriculture in the area, identifying specific constraints for each domain.

Rachel Slater · Development Southern Africa · South Africa

This study examined urban agriculture (UA) in Cape Town, South Africa, focusing on its contribution to low-income households. It found that UA's contribution to income generation and expenditure substitution is limited. However, UA is important to women in low-income households in ways less directly related to monetary gain, being used for empowerment, establishing social networks, symbolizing a sense of security, and encouraging community development.

World Vision Ethiopia launched a Micronutrient Program in October 1998 to improve the micronutrient status of mothers and children, promoting vitamin A–rich food production. By 1999, 11,708 backyard gardens, 275 school gardens, and 77 community gardens were developed, contributing to household food security and income. The program found that vitamin A–rich vegetable production was well accepted, sustainable, and cost-effective, but faced challenges with the availability and cost of imported seeds.

Dick Foeken, Samuel Owuor · · Kenya

A 2001 study examines "multi-spatial livelihood" households — those with a livelihood foothold in both urban and rural areas — from the urban perspective, based on Nakuru Town, Kenya. According to 1999 survey data, over 60% of Nakuru households can be considered to have a multi-spatial livelihood. While one-adult and low-income households are relatively under-represented in the survey, multi-spatial livelihoods may be particularly important for the food security of the latter group. However, the results indicate that rural farming by urban dwellers should be understood mainly in terms of "opportunity," in contrast to urban farming, which is framed in terms of "necessity."

This longitudinal study evaluated the effects of agroforestry practices (integrated tree-crop systems) on yield gains and farmer adoption rates in the Kibera slums of Nairobi, Kenya, using surveys and soil analysis as quantitative data collection methods. Preliminary findings indicate that integrated tree-crop systems produced a statistically significant 12% increase in maize yields (95% CI: 6-18%) compared to conventional farming practices. Farmer adoption rates rose from 40% at baseline to 70% after one year of intervention.

A survey of 150 Nigerian immigrant families living in various regions and cities across Nigeria, recruited via online questionnaires distributed on social media, examined the role of community gardens in social cohesion. Analysis found that 72% of respondents reported increased feelings of community belonging linked to their involvement in community garden activities, indicating these spaces play a role in fostering social cohesion among this immigrant population. As an exploratory study, the findings are preliminary, and the authors call for further research to validate them and to examine the long-term impacts of community garden participation on family dynamics, mental health and overall well-being among immigrants in Nigeria.

Chinwe Okonkwo · Zenodo (CERN European Organization for Nuclear Research) · Nigeria (Lagos)

A study in low-income Lagos neighborhoods, Nigeria, qualitatively explored the perceived impact of urban vertical farming projects on household dietary diversity. Data were collected through in-depth interviews with 24 household primary food providers participating in vertical farming initiatives and focus group discussions with project facilitators. Participants reported a marked increase in regular consumption of leafy green vegetables, and a "substitution effect" was observed where savings from home production were redirected to purchase other nutrient-rich foods.

Dick Foeken, Samuel Owuor · Leiden Repository (Leiden University) · Kenya (Nakuru)

A general survey was conducted in June-July 1999 on farming practices by inhabitants of Nakuru town, Kenya. The survey collected basic data on the extent of farming, types of farming, food produced, inputs used, constraints faced, characteristics of farming households, reasons for urban farming, and the extent of rural farming by town dwellers.

Paule Moustier · Agritrop (Cirad) · Africa

Case studies conducted in Africa on urban household food supply systems evaluated the relative roles of urban and rural agriculture. These studies highlighted a strong complementarity between urban and rural sources in terms of products and periods, linking these observations to differences in production and marketing systems. To stabilize urban food supply in quantity and quality, support programs for farmers and traders should target both urban/peri-urban and rural areas in a differentiated but articulated manner.

This article presents recommendations and policy directives for urban agricultural initiatives, based on an evaluation of Abalimi Bezekhaya's gardening promotion activities in Cape Metropolitan Area townships. Field research used participatory methodologies with gardeners to understand their motivations, constraints, and opinions on Abalimi Bezekhaya's services. The evaluation suggested improvements for the organization's services and highlighted urban agriculture's potential as an entrepreneurial activity, provided policy, agricultural development, land reform, and livelihood creation issues are addressed.

Dick Foeken, A. Mboganie-Mwangi · Leiden Repository (Leiden University) · Africa

Using survey data collected in 1994 in Korogocho, one of Nairobi's slum areas in Kenya, this study examined whether access to farmland influences a household's food situation. Access to land had a positive impact on urban households' overall welfare, but not necessarily on their food situation. Households with access to a rural plot appeared better off in terms of self-reported food situation than households without any land access, and access to rural land appeared more favorable for food situation than access to urban land alone. Among the very poor households in Korogocho who claimed access to rural land, half did not actually use that land themselves.

A. Mboganie-Mwangi, Dick Foeken · Leiden Repository (Leiden University) · Kenya (Nairobi)

A 1996 study in Nairobi, Kenya, compared the food security and nutritional status of low-income households engaged in urban agriculture with those not farming. It found that urban farmers primarily produced for home consumption and faced theft as a major problem. While the Undugu Society Urban Agriculture Project (USUAP) group showed better food situations and higher energy and protein intakes than other groups, all three groups had inadequate energy intake on average. The long-term beneficial effect of urban agriculture on nutritional status was negligible.
