CompostOrganic cycleToxic heavy metals distribution in urban soils of Africa: a systematic review
2026Nontokozo Pertunia Mkhonza, Sandisiwe Zondo, Samukelisiwe Vilakazi · Environmental Monitoring and Assessment · Africa
A systematic review synthesising 38 peer-reviewed studies (2010–2024) on heavy metals in African urban soils. Weighted mean concentrations of lead, cadmium and chromium exceeded FAO permissible limits in many countries, and industrial activity plus traffic emissions accounted for over half of the identified contamination sources. The review also documents strong geographic bias — Nigeria and Ghana are well studied while Egypt and Ethiopia are barely covered — and a shortage of measurements of bioavailable metal fractions, so the actual dietary risk from crops grown in these cities cannot be determined from this evidence base.

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.
