An ecological based approach for determining suitable landfill : The case of Kilis / Turkey

Aim: The present study aimed to develop a ecologically based approach to determine appropriate locations for landfill sites. Methodology: This study was conducted in Kilis, where the population is increasing and under risk due to wrong area management. This study consists of the processes of determining-evaluating the criteria of selecting sites and mapping these criteria with holistic approach. In the process of determining the criteria, Analytical Hierarchy Process (AHP), which is one of the multi-criteria decision making (MCDM) methods and in the mapping process, Geographical Information System (GIS) technology was used. In the study, the main criteria for selecting areas for landfill sites were determined to be aspect, proximity to settlements, proximity to seasonal and dry streams, proximity to main roads, land capability classes, rock type and soil water permeability. "Suitable landfill sites" related to the study area were mapped based on these criteria. Results and Interpretation: As a result, the map of suitable landfill sites produced in this study is an important ecological guide andits necessity for spatial planning should be ensured.
