Urban Landfill Investigation for Managing Negative Impact on Geo Spatial Environment in the Context of Ethiopian GTP 2 Goal of Sustainable Environmental Management A Case of Woliyta Soddo town

Bereket Geberselassie Assa


As many scholars showed that the intervention of humans on the natural environment influences the nature of ecosystem processes by the rate at which they operate on environment . In addition to poor urban planning and management  has always negative impact on environment, economy, ecology and heath problem in community . Therefore, landfill has to be selected carefully by considering both land use regulations and constraint in regarding to landfill site selection analysis in case of Wolayta Soddo town has been selected as case study. due to poor waste disposal and management system in the study area often end up in drains, causing blockages that result in flooding, unsanitary conditions and cause very effective vectors (flies) to spread disease like malaria, including acute water diarrhea and typhoid fever, which are current existing problems in Wolayta Soddo town due to inappropriate waste disposal site. and based on problem existence of Soddo town solid waste disposal system, the object was developed to conduct suitable solid waste disposal site and least cost path using Geographic Information System (GIS) and Multi Criteria evaluation (MCE). In addition, In order to active the objective of this research, eight very important factors have been used such are: land use, soil, ground water, drainage, road, slope, Aspect and population using the method of weighted overlay technique for all selected factors in Arc GIS 9.3 and IDRISI 32 software to generated Analytic Hierarchical Process (AHP) Eigen vector matrix value. In addition, as the finding of this thesis, it has been showed; a 6ha of land of the study area was selected among the 32.49 ha of very high suitable site

Keywords: Analytic Hierarchical Process (AHP), Geographic Information System (GIS)
