Waste Disposal Management Using GIS and MCDAmodels: A Case Study of Kabul City

Urban, industrial, hospital, and other hazardous solid waste management is one of the critical environmentalproblems that big cities face it. Meanwhile, industrial and hazardous waste management is highly importantsince lack of proper planning and management can lead to the wide pollution of surface and undergroundresources, soil and air. Accordingly, especial wastes management is one of the main stages of comprehensivewaste management. This stage requires paying a special attention as well as considering its management andcontrol system. Waste disposal localization is another important issue in comprehensive especial wastesmanagement. Localization is very important; therefore, many factors including geology, faults situation,hydrology and underground water resources, surface water resources, military urbanization and legalrestrictions, distance, and other parameters should be considered to select disposal locations with the leastenvironmental dangers in the future. Geographical information systems (GIS) are one of the new methodsemployed for localization studies. The purpose of the present study investigated especial wastes disposalmanagement in Kabul City of Afghanistan using GIS. In this regard, remote sensing and GIS with multicriteriadecision making models such as DEMATEL, ANR, and PROMETEE, and SAW model wereemployed to standardize and integrate layers to determine optimal sites for urban waste disposal. As thefindings revealed, integrative employment of images, remote sensing and GIS for urban waste disposallocalization can help appropriate locations identification. Also, land use maps with the suggested wastedisposal zones resulted by GIS-based localization along with multi-criteria decision making models werehelpful.
