Abstract
Solid waste management system is that the foremost difficult task that lots of nation, both developing and developed, are facing. Landfill method is one in every of the easy and cheap solid waste dumping site management systems which are always required for sustainable management of solid waste site selection. The foremost objective of this study was to spot environmentally sound, socially acceptable and economically feasible landfill site for the solid waste dumping in Adama city. To achieve the objectives, this study was conducted by integrating Geographic data System (GIS) and remote sensing for selecting suitable solid waste disposal sites. All factors were represented with map outputs which are classified and standardized by GIS and RS for environment preparation of site suitability analysis map. Analytical Hierarchy Processes pair-wise comparison component was done to derive weights for all aspect parameters. Some criteria in selection suitable site for landfill site selection were set. These were distance to road, distance to river/stream, sort of soil, land use/land cover and degree of slope effects on the study area. Accordingly, 52.04% of the study area was unsuitable, 1.15% of the study area is current not suitable, 44.64% is moderately suitable and 1.77% is extremely highly suitable for landfill supported predefined criteria. The study proofed that the application of GIS and remote sensing technique for the identification of suitable solid waste dumping site will minimize the environmental hazard and human health difficulties. In general, site selection required appropriate data set generation and site identification as, applied within the study.
