A survey of 160 pig farmers in five suburbs of the Cape Metropole District, South Africa, analyzed the impact of socio-economic factors on marketing practices and challenges. Key challenges included slow pig growth rates (54% of respondents), scarcity of production inputs (25%), and difficulty finding marketing information (20%). The study found that women, older farmers, and those with less experience or education were more likely to face challenges and fail to adopt sustainable marketing practices.

A mixed-methods, cross-sectional descriptive study of urban agriculture in Gulele sub-city, Addis Ababa, Ethiopia, examining perceptions, opportunities, and challenges. It combined a survey of employees and farmers, in-depth interviews with farmers, key informants, and experts, and a focus group discussion with civil service employees. The study identified scarcity of urban farmland, scarcity of water for irrigating vegetables, and constraints on various agricultural inputs as core problems, alongside market accessibility issues for selling produce and limited transportation availability, even as vegetable consumption and demand among urban dwellers were rising and government policy treated urban agriculture as a current priority. It also found a negative social attitude among urban dwellers toward urban agriculture, who regard it as old-fashioned work and view urban farmers as backward and uneducated. The study concludes that the Addis Ababa City Administration's urban agriculture development sector needs to work with research institutions to address pest and insect problems and to improve vegetable yield per unit of land.

This case study, conducted in a low-income South African community, explored how a community gardener engages with the social solidarity economy (SSE) using thematic analysis of triangulated data from an interview, participant observation, and a participatory film. The study analyzed how the community garden fostered solidarity and established alternative micro-economic practices. It also considered challenges facing community gardens when connecting with the SSE.

This study aimed to develop a sustainable social entrepreneurship model for urban farming initiatives in Johannesburg. Through a literature review and qualitative interviews with experts, findings highlighted several important challenges that limited urban smallholder farmers' ability to ensure the financial viability and sustainability of their farming initiatives. These challenges included limited accessibility to farming land, markets, funding, and knowledge regarding setting up and managing small agri-businesses.

This review discusses vegetable production in South Africa, focusing on the impacts of root-knot nematodes (Meloidogyne species) on small-scale farming communities. The review highlights that these nematodes are a primary pest, causing delayed crop maturity, reduced yields, poor quality produce, and escalating production costs. This leads to substantial income losses for farmers and the abandonment of community gardens, intensifying challenges for vegetable production and food security.

This research explored the potential of urban agriculture in Cape Town, South Africa, and Maputo, Mozambique, through two baseline surveys among urban farmers and home gardeners, as well as qualitative in-depth interviews. Findings indicated that urban farmers and home gardeners add nutrients and diversity to their diets and can partly contribute to their income. However, in Cape Town, main challenges included access to local and external markets, fair pricing, and sovereignty in production.

This paper reviewed the role of urban agriculture in socio-economic and environmental sustainability in Africa, drawing on theoretical and empirical literature. While urban agriculture is recognized for job creation, improved diet, and environmental benefits like urban greenery and biodiversity, challenges such as difficult land access, lack of experience, financial support, training, and credit facilities, as well as low land productivity, animal grazing, and theft, were identified. These factors present potential negative externalities and hinder the development of urban agriculture.

This study assessed the influence of urban agriculture on household income in Kogi State, Nigeria, using data from 120 urban farmers. Urban agriculture was found to increase household income at a 90% confidence level. However, urban farmers faced significant constraints including inadequate capital (M=2.9), poor extension services (M=2.4), and high labor costs (M=2.2).

This paper investigates the efficiency relationships between inputs and outputs of urban micro-farms in two Cape Town townships, Nyanga and Khayelitsha. Data Envelopment Analysis (DEA) applied to 33 producers supplying a social enterprise box scheme revealed an average overall efficiency of 72.4%. Overall efficiency was negatively correlated with land holdings and the use of compost and seedlings, indicating efficiency losses with greater input quantities. Furthermore, it was not shown that mulching or operator experience increases profitability.

This case study investigated the effects of climate change on agricultural activities in the Igbe Farming Community, Lagos, Nigeria, by surveying 161 farmers. The study found that most migrant farmers leased plots annually or biennially and made marginal profits of $200 to $350 per farming cycle. Erratic weather patterns and aggressive urban growth were major challenges, leading 48% of respondents to engage in informal enterprises.

This study examined two tomato production areas in Burkina Faso with potential for counter-seasonal production aimed at Ghanaian urban markets, identifying the main obstacles to developing a horticultural supply chain: the monopsony power of Ghanaian traders and insufficient road quality causing high mechanical-damage losses in transport. Using a spatial-temporal simulation model to assess transport effects on tomato quality, the study found refrigerated transport is not a necessary condition for successful trade, since climate conditions alone do not severely harm quality, and concluded that regional diversification of exports offers Burkina Faso producers the best opportunities for improving their position in the chain, given the persistent trader monopsony and infrastructure constraints.

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.

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.

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 sample survey of 242 urban vegetable farmers conducted through March 2006 examined production efficiency and its determinants in fadama agriculture — flood-plain cropping of short-duration crops on low-lying, seasonally flooded land — in urban southwestern Nigeria, using a stochastic frontier model. Mean farm size was 0.54 hectares and mean producer age was 42.6 years, while mean technical efficiency was only 74.36%, with the main sources of inefficiency identified as labor employment and the use of land and seed/cultivar resources; the most common crop combination was Telfaria occidentale, Amaranthus hybridus and Zea mays.

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.
