Barriers to urban agriculture in Africa: a bibliometric and content co-occurrence analysis of the literature
2026hawamkwela@yahoo.com MKWELA, Emiliana Assenga · Cogent Food & Agriculture · Africa
A bibliometric analysis of 504 journal publications from January 2020 to December 2024 and a content co-occurrence analysis were conducted to understand barriers to urban agriculture in Africa. Four research clusters emerged, including 'policy neglect or opposition in urban agriculture'. Content analysis revealed that vegetable production in urban agriculture is negatively affected by wastewater use, heavy metal contaminated soil, limited access to productive factors, and policy neglect or opposition.

2026Amos Tomiwa Afolabi, Bridget O. Odiyi, Oluwasheun Johannah Ojeniyi · Discover Soil. · Nigeria (Ado-Ekiti)
A study in Ado-Ekiti, Nigeria, investigated heavy metal accumulation in Amaranthus hybridus and Ocimum gratissimum grown on soils from two automobile workshops. A. hybridus accumulated higher metal concentrations than O. gratissimum, with stems showing greater accumulation than leaves. While non-carcinogenic and total cancer risks were within acceptable limits, children showed higher vulnerability, indicating that continuous monitoring and soil remediation are essential for sustainable urban agriculture in these contaminated areas.
Contamination & food safetyHealthUrban Agriculture as a Survival Strategy: Food Security, Inequality, and Community Development in Enugu State, Nigeria
2026Oshaba Patience Chizoba, Chinedu Augustine Igwenagu · Path of Science · Nigeria
A survey of 222 households and interviews in Enugu State, Nigeria, showed that urban agriculture (UA) is a critical coping strategy for food availability. However, UA perpetuates gendered inequalities as a "patriarchal bargain," where women's expanded reproductive labor does not necessarily lead to improved economic empowerment. Furthermore, UA strongly promotes bonding social capital but does not foster bridging social capital with formal institutions, thereby undermining its transformative potential.

2026Never Assan, Justice Sibanda, Betty Mukuwapasi, Reason Rumbidzai Charachimwe, Edmore Masama · Journal of Frontiers in Multidisciplinary Research · Sub-Saharan Africa
Urban animal agriculture (UAA) in Sub-Saharan Africa is presented as a solution for food security but faces challenges including gender inequality, climate change, inadequate legislation, and environmental degradation. While UAA aims to enhance household food security and alleviate poverty, it also encounters environmental issues such as resource competition, water resource strain, improper manure management, greenhouse gas emissions, noise, and nuisance. Sustainable UAA requires semi-intensive silvopastoral and mixed crop and livestock systems to reduce environmental impact and enhance local food production.

2026Abie Assres Fenta, Habtie Anmaw · Discover Sustainability · Ethiopia (Debre Markos)
This qualitative study explored the adaptive livelihood strategies of evicted peri-urban farmers around the metropolis of Debre Markos, Ethiopia. Findings confirmed that farmers tend to hand over their land with insufficient compensation and are compelled to adapt to new livelihoods after losing farmlands. Many displaced young farmers experienced bankruptcy in new businesses due to a lack of business skills, and aged displaced farmers faced challenges adapting to new ways of life. The government did not provide adequate attention to training evicted farmers in technical, financial, and business planning.

2025Aminu Zakariyau, Murtala Rabiu · International Journal of Advances in Engineering and Management · Nigeria (Katsina City)
The potential ecotoxicological impacts of municipal solid waste compost (MSWC) on soil, plants, and humans in urban Katsina, Nigeria, were assessed. Analysis of soil mixtures and plant biomass (maize and beans) revealed high phytotoxicity in beans, while maize considered MSWC as phytonutrients. No statistical difference in non-biodegradable substance concentrations in soils and plants was found, and ecological risk index (ERI) indicated low risk; however, Target Hazard Quotients (THQ) suggested a likelihood of non-carcinogenic effects to the ecosystem.
