2019Nicolette Tamara Jonkman, Boris Jansen · Current Opinion in Environmental Sustainability · Sub-Saharan Africa
This literature review on urban agriculture (UA) in Sub-Saharan Africa (SSA) identifies a significant constraint: conflicting stakeholder perceptions of UA, which hinders its development into a sustainable business. Some view UA as illegal and unsustainable, while others see it as a means to food security and employment. The review highlights a knowledge gap regarding land-use history and its effect on UA soil composition and nutrient status, proposing that UA sustainability requires understanding this historical context to build inclusive business models.

2017Volker Häring, Delphine Manka’abusi, Edmund Kyei Akoto-Danso, Steffen Werner, Kofi Atiah, Christoph Steiner, Désiré Jean‐Pascal Lompo, S.G.K. Adiku, Andreas Buerkert, Bernd Marschner · Scientific Reports · Sub-Saharan Africa
This 2-year study in Tamale (Ghana) and Ouagadougou (Burkina Faso) investigated the effects of biochar, wastewater irrigation, and fertilization on sandy, nutrient-depleted soils in urban vegetable production. Biochar addition (2 kg m⁻²) initially doubled soil organic carbon (SOC) stocks, but 35% SOC losses occurred afterward. Both biochar types had no effect on soil pH, phosphorus availability, or cation exchange capacity, though rice husk biochar retained nitrogen. The study found that the effects of biochar and waste water were less pronounced than reported elsewhere.

2013R. O. Yusuf · · Nigeria (Kaduna State)
In Zaria, Kaduna State, Nigeria, a study examined the contribution of urban farming activities utilizing water from excavation pits to farmers' income and food security, and the eco-supportive component of using these pits. Data were collected from 10 farmers between December 2011 and May 2012 through structured interviews and observation. Farmers cultivated various crops and obtained higher incomes from farming compared to their primary occupations. The utilization of excavation pits was found to be eco-supportive by regulating the microenvironment's water balance, serving as carbon sinks, and providing low-cost water extraction. However, observed constraints included insecure land tenure, disturbance from straying domestic animals, and theft of farm produce.
