Abstract


Floods are waterinduced disasters that lead to temporary inundation of dry land and cause seriousdamages in the affected location such as loss of lives and properties anddestruction of infrastructure. The management of flood risk begins withidentification of flood prone areas and preserving such areas as buffer, carbonsink or vacant lands because of the danger of developing them for either residentialor commercial concerns. This study used the scientific technique of GIS toidentify flood risk areas in suburb of Minna, North-Central Nigeria. Thispaper  aimed at assessing the impact ofdeveloping floodplains and marginal lands. This is done through mapping offlood plain, determine the rate and level of development of flood plain; andevaluation of the consequences of floodplain development. Primary and secondarydata were collected using the quantitative instruments of questionnaire and GISsoftware. The findings of this research have shown that the quest for land forstudent housing have led developers to encroach dangerously on flood plains,watershed and marginal lands. There is therefore the need to carry-out acomprehensive redevelopment and reclamation of all flood prone areas in thestudy area. It is also critical for the Niger state urban development board torise to the task to floodplain protection as a strategy for climate changemitigation and sustainable environmental development.  This will go a long way in the preservationof city landscape, provide carbon sink; space for urban agriculture and aboveall promote a safe, healthy and sustainable living environment.
