However, siting landfill is an extremely complex task mainly due to the fact that the identification and selection process involves many factors and strict regulations. For proper identification and selection of appropriate sites for landfills careful and systematic procedures need to be adopted and followed. Wrong siting of landfill many result in environmental degradation and often time public opposition. In this study, attempts have been made to determine sites that are appropriate for landfill siting in Damaturu town Nigeria, by combining geographic information system (GIS) and a multi-criteria decision making method (MCDM) known as the analytic network process (ANP) for the determination of the relative importance weights of factors (criteria). The land suitability output is presented from less suitable to the most suitable areas. The final map produced show areas that are suitable for landfill siting. Based on the analysis fourteen sites were identified to fulfill the required criteria, however, only seven met the land availability criteria of twenty hectares and above. The results showed the efficacy of GIS and multi-criteria decision making method in decision making.展开更多

It lacks adequate water supply. Being a State Capital, rapid improvements in itsinfrastructures including water supply to cope with increased demands are required. Three options forthe expansion of the present water supply system are been considered. These are Groundwater resourceswithin and around the existing system, and surface water schemes from two Dam sites identitied andappraised for this purpose. The Management of the Yobe State Water Board and the State Governmentare faced with the problem of which of these three options to choose. This is a typical capacity expansionproblem within a multicriterion setting in which the choice is to be bassed on economic, environmental,social as well as political considerstions. This paper presents a multicriterion analysis whose result willbe used in forming the basis of an informed decision to be made on why a particular option is to bechosen.展开更多

Damaturu town became a state capital in August 1991. Since then the population has been on a steady increase mainly due to influx of people and its strategic location along axial route to major cities in the northeast region. Wastes are being generated mainly from residential, commercial and institutional land uses. Waste collection bins are placed at strategic locations identified by the agency and termed as high waste generating points with wheeled plastic waste bins, metal waste bins and constructed waste bunkers. The contents of these bins are finally disposed of at a location 6 kilometers away from the generating points. Spatial data on waste distribution was collected using a global positioning system (GPS). The data was manipulated and processed using Geographic information system (GIS) to produce the waste distribution map. Findings revealed that the existing solid waste management system is inefficient as the present practice rely on monthly collection and disposal of waste using an open dump site.展开更多
