Effects of Urban Agriculture on the Socio-Economic Status of Farmers in Cities of Sub-Sahara Africa. A case of Zambia, South Africa, and Nigeria: A Review
2024Leonard Ninsheka, Edward Ssemakula, Christopher Ewaechabo Tiyo, Rebecca Kalibwani, Ronald Kityo, Wilson Mugizi, Willbroad Byamukama · East African Journal of Agriculture and Biotechnology · Sub-Saharan Africa
This review paper examines existing literature on the effects of urban agriculture on the socio-economic status of urban farmers in Sub-Saharan African cities, specifically focusing on Zambia, South Africa, and Nigeria. The review found scanty information regarding how urban agriculture affects farmers' socio-economic status, how farmers derive social and economic status from it, and the types and motivations of farmers. It concludes that understanding crucial factors for food security, income, and related benefits in urban agriculture is essential for policy and technology development.

2024Stefania Lovo, Samantha Rawlings · The World Bank Economic Review · Ghana, Nigeria
This study investigated the impact of e-waste dumping sites on neonatal and infant mortality, focusing on two major dumpsites in Ghana and Nigeria. Using a difference-in-differences approach, outcomes were compared for children born near and far from dumpsites before and after their creation. E-waste sites increased neonatal and and infant mortality for those living closer to the sites, with event studies suggesting effects emerge two to three years after site openings. There is suggestive evidence that contamination of water and of urban farming produce are among the drivers of the observed effects.
