An Investigation on Rout Network Analysis by Raster Method in the Context Sustainable Solid Waste Management A Case of Wolyta Soddo

Abstract

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 inappropriate solid waste transportation has always negative impact on environment, economy, and ecology heath problem in community. Those are a growing problem for national and local governments to ensure effective and sustainable management of environmental sanitation and due to lack of controlled waste management and Unmanaged wastes transportation often results solid wastes to 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 Wolyta Soddo town and the object was developed  to conduct suitable route by least cost path method using Geographic Information System (GIS) and Multi Criteria evaluation (MCE) since waste transportation is one part of solid waste management. In addition, In order to active the objective of this research, seven very important factors have been used such are: master plan, land use, road, slope, aspect, source date sate and destination point using the method of weighted overlay technique for all selected factors in Arc GIS 10.1 and IDRISI 32 software to generated Analytic Hierarchical Process (AHP) Eigen vector matrix value.
