The place of geoinformatics in waste management, sanitation and health risks prevention in Ado-odo/Ota local government area

Increasing population growth, lack of suitable waste treatment and disposal sites, in addition to inadequate equipment for waste recycling, poor town planning, accumulation of waste beside the roads and canals caused by inadequate waste collection and lack of enough data and information on waste generation could be observed as palpable causes of inadequate waste management in our societies, as well as sources of environmental pollution. This paper considered the applications of Geographic Information Systems in the selection of suitable land fill sites in Ado-Odo/Ota LGA. Geospatial data of the study area were obtained, buffer, overlay and intersection analysis were carried out to exclude non-suitable locations and identification of suitable sites. The suitable locations for landfill were selected, and we concluded that GIS is a veritable tool in qualitative decision making in environmental management and sustainable development. (paper)
