A study of the rate and direction of spatial expansion of Robe Town, Ethiopia, into surrounding rural kebeles, and its effect on the tenure security of peri-urban landholders. It combined socioeconomic data from 202 sampled household heads with spatial data from Landsat images taken in 1987, 2002, and 2020. The town grew annually by 18.6% (1984–1994), 11.3% (1994–2007), and 9.3% (2007–2020), with its total area rising from 5.1 km² in 1984 to 80.2 km², a 40.9% overall increase. Over the 33-year period, built-up area expanded fastest southward, reaching 9.91 km from the town's mean center, and grew from 4.38 km² in 1987 to 27.9 km² in 2020; about 10.2 km² of farmland was converted to built-up land between 1987 and 2020. In peri-urban areas of Robe town, 48.9% of landowners lost around half of their farmland, leaving peri-urban landowners feeling insecure about their tenure due to fear of eviction and expropriation at minimal compensation.

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 study investigated the determinants of sustainable growth for SMEs, including those in urban agriculture, in Ethiopia using primary data from 194 employees. Findings indicate that political instability, corruption, and COVID-19 are significantly harming the growth and long-term sustainability of Ethiopian SMEs.

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 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.

Using a combination of remote sensing and GIS, this study assessed the rate of agricultural land-use change in the Kaduna metropolis, Nigeria, between 1980 and 2012, classifying and comparing four satellite images (Landsat MSS 1980, Landsat TM 1990, Landsat ETM+ 2005, and Nigeria Sat X 2012). The study found a significant reduction in agricultural land and continued disappearance of farmland over the period, which it links to loss of livelihoods, reduced food supply, and increased poverty. It states that this has raised concerns about the sustainability of urban and peri-urban agriculture (UPA) production in the study area, with small-scale farmers the most affected.

Phil. Caleb Mireri · African Journal of Agricultural Research · Kenya (Kisumu)

This study surveyed 194 urban farmers in Kisumu municipality, Kenya, to assess urban agriculture's role in income, employment, and food supply. It found that most urban farmers and their employees receive very low income, with a mean monthly income of US$135 (US$0.64 per person per day), which is below the acceptable one dollar a day per person. Urban agriculture primarily supplements food requirements for the urban poor and provides income for a few commercial farmers.

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.

This paper evaluates the efficiency of resource use in urban food crop production in five districts of two cities in southwestern Nigeria, based on an effective sample of 120 respondents. The analysis showed that urban food crop production is profitable, with an average revenue of N51,294 per hectare and a gross margin of N23,688. However, there was disequilibrium in resource use, with planting seeds and agrochemicals used efficiently, but land and labor used inefficiently, indicating that urban food crop production has not yet attained an optimum level of resource combination.
