A study in Johannesburg, South Africa, assessed urban transformational strategies, including rooftop gardening and hydroponic farming, aimed at improving food security and regenerating infrastructure. Using open-ended interviews with stakeholders, findings indicated improved household food security and income generation, but challenges such as soil and water flow for rooftop gardens persist. Hydroponics faced hurdles like energy supply and input costs, though it showed more promise for land and water resource efficiency.

This study assessed the perceptions of youths (aged 18-35 years) about urban agriculture and factors influencing their participation in Ibadan metropolis, Nigeria. Data analyzed using descriptive statistics, Likert analysis, and logit regression showed that 38.8% of youths participated in urban agriculture, and access to urban farmland, being a married male, and older youth increased the likelihood of participation. Conversely, longer market distance, higher formal education, and poor access to credit and land reduced participation.

Mallika Sardeshpande, Charlie M. Shackleton · People and Nature · South Africa

This study interviewed 80 urban foragers in four cities in South Africa's eastern coastal region to understand urban foraging in a developing nation context. Foragers began foraging in childhood, viewing it as a cultural and recreational activity, but formal green spaces were not used for foraging and were perceived as poorly provisioned in urban planning. This indicates a lack of governance in urban planning regarding foraging.

This mixed-methods study examined 34 urban community gardens in Cape Town, South Africa, to assess their capacity to function as urban commons across six areas: infrastructure, inputs, land, produce, labour, and immaterial components. Findings demonstrated that while these gardens counter neoliberal privatization and individualization, their capacity to function as urban commons is significantly curtailed by their entrenchment within the neoliberal context.

This mixed-methods study surveyed 120 community garden participants in Ward 18, Umdoni Municipality, South Africa, to assess the impact of community gardens on household food security. The survey found that 58.3% of participants did not receive sufficient food from the gardens, and only 15.8% achieved food security, with 40% experiencing moderate food insecurity. Despite their establishment, community gardens appeared ineffective in substantially improving household food security, with challenges including climate change impacts.

This study assessed the impact of a nutrition intervention using African indigenous leafy vegetables (AILVs) grown in school gardens in Machakos County, Kenya, on body composition changes in school-going children (6-10 years) using the Deuterium Dilution Isotope Method (DDIM). An experimental cross-over design with two phases (Phase I: 13 weeks, Phase II: 12 weeks) was used, with 66 children in the experimental group and 46 in the control group in Phase I. Findings indicated high morbidity and low nutritional status, poverty, and poor AILV consumption among subjects, but DDIM showed a significant improvement in body composition in experimental groups (p<0.001).

This case study investigates the relationship between prior land use, current management, and soil quality at six urban agriculture (UA) sites in Kisumu, Kenya, and Ouagadougou, Burkina Faso. A soil survey determined the soil macronutrient and mineral composition. Results indicate that three UA sites predate surrounding urban development, and soil nutrient data suggest these sites were likely chosen for their soil.

A survey of 218 randomly sampled micro and small-scale enterprise (MSSE) managers/owners across manufacturing, trade, construction, service, and urban agriculture sectors in Dessie Town, Ethiopia, used self-administered questionnaires and stratified random sampling to identify determinants of enterprise growth. Of nine candidate factors, statistically significant associations with MSSE growth and performance (at the 5% level) were found for political/legal factors, management, market conditions, technology, infrastructure, entrepreneur-related factors, and the COVID-19 pandemic.

Habtamu Serbessa, Teferee Mekonnen, Meskerem Abi · Journal of Developing Country Studies · Ethiopia

A questionnaire survey and focus group discussions with small-scale vegetable producers in Addis Ababa, Ethiopia used probability sampling, descriptive statistics, correlation and multinomial logistic regression, plus SWOT and force field analysis. Producers held positive perceptions of vegetable production and most intended to continue, but limited access to land, pests and diseases, and water shortages were identified as the main challenges. Regression results showed land size, gender, age and housing type as the most significant factors determining vegetable production.

Habtamu Serbessa · International Journal of African and Asian Studies · Ethiopia

This study examined how vegetable production supplements food and income for residents of urban Addis Ababa, Ethiopia, using household-level quantitative data analyzed with descriptive and inferential statistics. Of respondents, 99.2% said vegetable production provides fresh food for their households, 41.9% earned up to 10,000 birr per production cycle, and 30.7% of producers hired up to ten employees, with seeds and pesticides being the more expensive inputs; multivariate analysis found households earning around 10,000 birr per production cycle were significantly affected by farming in residential areas (p = 0.008), and households were found to prioritize food consumption over profiting from sales.

Nada El Habibi, Hesham El-Barmelgy · Journal of Urban Research /Journal of Urban Research · Africa

This paper addresses urbanization pressures and food security challenges in Egypt, along with the negative impact of a shortage of green space on public health and productivity, by examining the concept of urban agriculture and how to activate it. Using an analytical review of literature and international experiences, the study identifies the main patterns and types of urban agriculture, analyzes global cases to understand the potential contributions and challenges facing different urban agriculture types, and, through a deductive approach, proposes a framework for activating the urban agriculture concept as a pathway toward sustainable urban development in Egypt; the paper presents no empirical survey data.

This study examined the effects of urban agriculture on households' livelihoods in Ondo State, Nigeria, using a multistage sampling procedure with 150 respondents. Major crops and livestock were leafy vegetables (100.0%) and broiler chickens (57.0%), respectively. The majority (82.0%) of urban agriculture practitioners had no contact with extension agents. Urban agriculture significantly improved respondents' standard of living (from 85.0% to 98.0%) and saving patterns (from 66.7% to 100.0%), and also led to improved knowledge.

In Maputo, Mozambique's capital, urban agriculture is at a critical point, with accelerated urban growth and climate change impacts increasingly compromising agricultural spaces. A qualitative case study focusing on farmer associations in the urban district of KaMavota indicated that horizontal relationships among farmers enable information sharing and social capital creation. Conversely, vertical relationships between farmers and the government primarily promote knowledge exchange and competencies related to agricultural extension and land rights allocation.

In Katuba municipality, Lubumbashi, Democratic Republic of Congo, irrigation water, soil, and harvested amaranth from an area of urban amaranth cultivation were analyzed for chemical and microbiological pollutants. Water and amaranth were polluted on both mineral and microbial fronts, while soil was not; water samples contained Paramecia, Entamoeba histolytica eggs, fecal contamination indicator germs, mesophilic flora, and pathogens including Aeromonas hydrophila and Pseudomonas aeruginosa. Amaranth cobalt concentrations exceeded quality standards and the plants were contaminated with Paramecia, Entamoeba histolytica eggs, Escherichia coli, and Klebsiella planticola, leading to the conclusion that consuming these amaranths poses health risks to the population.
