Green spaces provide flood-regulating functions that help minimize the impact of flooding. However, in urban Africa, rapid urbanization has led to the decline and deterioration of greeneries, which have adverse outcomes on the preparedness of cities to respond to ecological disasters, particularly flooding. Through the review of eight relevant urban planning documents and interviews with relevant urban planning institutions, this study found that city officials had considerable knowledge and acknowledged the significance of green spaces in minimizing flood occurrence and its impacts. This notwithstanding, the interviews and analyses of the urban planning documents showed some clear attempts to integrate green space planning into flood management interventions in only three of the policy documents. Political interference, financial constraints, and inadequate logistics, were mentioned as the notable challenges toward successful integration of green space planning into flood management efforts. The study recommends the conscious inclusion of green space planning into flood management efforts towards minimizing the occurrence and adverse impacts of floods.
