A Multi-criteria Analysis For Solid Waste Disposal Site Selection Using Remote Sensing And Gis

Solid waste management continues to be one of the major issues facingrnmunicipal planners, which Involves managing activities associated withrngeneration, collection, transport and disposal of solid waste in an environmentallyrncompatible manner. Land filling is a common method of waste disposal inrnEthiopia. Recently, due to an increase in the awareness of environmental risksrnfrom land fills, there has been a movement towards the selection of new solidrnwaste disposal sites for the city, however due to the lack of appropriate criteriarnand a set of detailed criteria that consider all aspects of the water resourcernprotection all the results of the previous researches were inadequaternIn order to alleviate this acute environmental problem, a multi criteria analysisrnapproach using remote sensing and GIS is necessary and immediate.rnGIS can be used to convert geo-referenced data into computerized maps andrnmap analysis tools can be used to manipulate maps in an efficient way. This isrnespecially useful when dealing with large amounts of data, which is typical inrnlandfill sitingrnThe result of the study shows that the areas, the city planners proposed for thernlandfill site be revised in a way to consider the best sites, some areas of therncentral east and southern part of the city, are appropriate as land fill site shown inrnthe final out put map of the study area.
