In South Africa, traditional leafy vegetables have been labeled as weeds since the 1960s, leading to a negative perception and unwillingness to use them. Awareness activities in six communities, including training sessions in seven schools and eight community gardens, aimed to improve the status of these crops. These activities resulted in increased awareness of their poor conservation status, appointment of seed keepers, and a noticeable increase in demand for seeds and production training.

This paper reports on research and city consultations in seven West African cities, examining the institutional aspects and constraints of urban agriculture. Despite growing interest from public authorities, this has not led to effective consideration in institutional and legal provisions in most countries. Decentralization processes have also not resulted in city government commitment to support urban agriculture, and its legal status remains uncertain.

This field survey in the Modder River basin, South Africa, investigated the potential expansion and implications of a rainwater harvesting technique introduced to small-scale farmers. While a rapid spread within home yard sizes was expected, no significant spread to community gardens or beyond was anticipated in the short term. This limitation was attributed to socio-economic constraints, including poverty and a lack of appropriate tools and basic farming skills.

Alice J. Hovorka · Annals of the Association of American Geographers · Africa

This study empirically examines the effects of gender on commercial urban agriculture in Greater Gaborone, Botswana, using a conceptual framework bridging sociospatial and human-environment geography. It found that gender clearly shapes both the quantity and type of foodstuffs produced for the urban market, with men and women farmers entering production and participating in this economic sector on unequal terms defined by socioeconomic status, location, and environmental interaction. The study argues that gender relations of power, as produced through sociospatial and human-environment relations, remain an unequal structuring force in the sector that must be accounted for if urban agriculture is to support food security and economic growth.

Christian M. Rogerson · Acta Academica Critical views on society culture and politics · South Africa

This article examines international and South African research on urban agriculture's role in poverty reduction, arguing for the need for policy guidelines to support local initiatives in South Africa. It suggests that best practices from international urban agriculture policy interventions could form the basis for such guidelines.

Mulu Tesfay Gebru · Zenodo (CERN European Organization for Nuclear Research) · Ethiopia (Addis Ababa)

This research in Addis Ababa, Ethiopia, investigated community gardens as urban food security initiatives, collecting data through surveys and market analysis. Seasonal fluctuations showed vegetable production peaked during the rainy season, contributing up to 30% of total annual harvests. Economic models indicated a positive correlation between garden size and local income generation, highlighting the potential of community gardens for food security and economic stability.

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.

Gina E. Castillo, S. Langeveld · WIT transactions on ecology and the environment · Africa

This paper examines the contributions of civil society organizations working on urban agriculture in Africa and Latin America. It argues for the need to develop land use policies that incorporate the social, economic, and environmental benefits of urban gardens. The paper concludes that both urban agriculture and civil society organizations are essential for creating livable cities.

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.

Sipho Maseko · Zenodo (CERN European Organization for Nuclear Research) · South Africa (Cape Town)

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.

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.

It uses the NUTShell farm-diagnosis tool to link nutrient flows with economic flows, without presenting specific case results.

Chinedum Nwokocha, Obioma Obiora, Oludamini Olayiwola · Zenodo (CERN European Organization for Nuclear Research) · Nigeria

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.
