Tiivistelmä
One of the growing potential problems of increased consumption is an escalation in the quantities of municipal solid wastes produced. Landfilling is now accepted as the most widely used method for environmentally safe disposal of solid waste. However, appropriate site selection for waste disposal is one of the major problems in waste management. Selection of suitable landfills can be extremely complex mainly due to the fact that the selection process involves many factors, criteria and regulations. In this study, attempts have been made to determine sites that are suitable for landfill siting in the Abuja municipalities and localities of Kaduna and Niger.
Geographical Information System (GIS) based methodology was applied in order to identify and select potential suitable sites. For this purpose, different criteria were examined in relation to landfill site selection. The initial step of the methodology comprises a GIS based operation and analysis that exclude all areas unsuitable for any waste disposal facility. Criteria were mapped using the GIS technique and spatial analytic tools, then different constraint map layers were overlaid to obtain a potential suitability map. The final map produced show areas that are suitable for landfill siting
Finally, at the end of the analysis and result, an application model that incorporate sustainability in the application stage of landfill planning was developed for municipalities to adopt and follow. The analytical technique and model proposed here will help municipal authorities make the right and sustainable choice on the selection and planning of landfill sites without compromising human health, the environment or future uses of natural resources.
