This study examined agricultural land use change in Lagos Metropolis, Nigeria, between 1984 and 2024 using Landsat satellite images and spectral indices. Findings indicated that farmlands in the study area declined by 13.03% between 1984 and 2013, and by 21.79% between 2013 and 2024. Between 1984 and 2013, 89.48% of farmlands were converted to other land uses, and between 2013 and 2024, 73.51% were converted. Normalized Difference Vegetation Index (NDVI) results also indicated a deterioration in the environmental condition of urban farmlands.

This study, conducted in the Amhara National Regional State, Ethiopia, examined the integrated effect of the entrepreneurial ecosystem's political-legal subsystem on the performance of Micro and Small Enterprises (MSEs) and the mediating role of entrepreneurial competence. A sample of 499 MSE operators engaged in manufacturing, construction, and urban agriculture was selected. While the political-legal aspects significantly impacted both entrepreneurial competency and MSE performance, the relationship between entrepreneurial competencies and MSE performance was found to be insignificant. The mediating role of entrepreneurial competency in the relationships between policy and business performance and other business environments and business performance was also shown to be insignificant.

This study investigated the association between urban agriculture (UA) and household food security in smaller African cities and towns, using survey data from 2,687 low- and low-middle income households in 18 urban areas with populations of less than 200,000 across Zambia and Kenya. The analysis found that 33% of households in the sample engaged in UA, but there was limited statistical significance in the relationship between UA and household food security. Key barriers identified were settlement formality, property rights, and distance from food retailers.

This study examined urban agriculture practices and land use changes in Lagos Metropolis, Sub-Saharan Africa, over three decades using satellite imagery and primary data from four Local Government Areas. It found that cultivated lands decreased by 28.70% between 1986 and 2000, and by 19.25% between 2000 and 2016. Urban farmlands converted to other uses by 89.48% between 1986 and 2000, and by 75.64% between 2000 and 2016, indicating that food security is under threat as land for urban farmers shrinks.

In Nairobi, Kenya, stratified random sampling, field surveys and questionnaires were used to identify existing water sources and wastewater treatment systems and their reuse status, in an investigation of the potential for eco-friendly urban and peri-urban agriculture (EcoUPA). Of the 300 respondents interviewed, only 66 (22%) reused wastewater, and only 54 of those reused it for crop production. Ninety-eight respondents (33%) wanted information on wastewater treatment systems allowing reuse, and 124 (41%) were willing to pay for a new system. The findings indicate that limited urban water sources constrain the spread of urban and peri-urban agriculture.

This article explores water resource management in Addis Ababa's condominium housing and urban agriculture cooperatives to identify challenges and potentials for water-resilient livelihoods. Findings indicate both communities are heavily affected by water stress, with farming communities being vulnerable due to natural asset dependence but more flexible than condominium residents facing malfunctioning infrastructure. Potential for resilience exists if policy frameworks integrate local situations with landscape-based stormwater management.

Sky Roberts, Charlie M. Shackleton · Land · South Africa

This study investigated urban community food gardens in four towns in South Africa, using surveys and GIS analysis over three decades. It found that common motivations included cash poverty (37%) and the need to grow food (34%), with reported benefits such as a healthy lifestyle (58%) and food consumption (54%). A significant challenge was theft of garden infrastructure or produce, and there were declines in the number and area of urban community gardens, with only 16% of gardens from the 1980s still operating in the 2000s.

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.
