Abstract

One of the threats to global environmental health is waste generation. Growth in population as well as rise in the quantity of municipal solid waste generated has made it difficult to locate appropriate site for waste disposal in most urban areas. Land filling is now accepted as the most widely used method for addressing this problem in all countries of the world. However, appropriate site selection for land filling is a problem in waste management and therefore needs to be addressed. This research sought to identify a suitable landfill site for waste disposal in Sekondi-Takoradi Metropolis of Ghana. To achieve this, Geographical Information System (GIS), Fuzzy Logic and Multi-criteria Evaluation (MCE) were applied in order to display and rank candidate sites. The analysis was limited to criteria that were selected and relevant to the area under investigation. The results obtained provide clear areas for landfill sites in the study area and finally arrives at suitable areas.
