The prevailing trend of waste disposal site in many parts of sub-Saharan Africa is detrimental to the environment on a long term. Waste disposal sites are randomly selected and frequently incinerated, releasing harmful gases which have negative impacts on the surrounding ecosystem and human life. The study area in Kwara State, Nigeria is a Microcosm of Africa’s unique challenge. The research is aimed at the determination of suitable landfill sites that engender environment sustainability. The proposed landfill sites were investigated using Geographic Information System (GIS), Geological, Geophysical and Geotechnical techniques as tools to aid the decision-making processes. To achieve the objectives, 2017 IKONOS Satellite imagery was used to identify geological features, soil, topo... view more»
