Abstract: Selecting an appropriate site for municipal solid waste (MSW) disposal is a significant challenge in solid waste management (SWM) for local authorities, engineers, and urban planners. Rapid population growth, industrialization, diverse community characteristics, and limited land availability exacerbate this issue. Landfill site selection requires evaluating numerous factors, including environmental, social, and economic considerations, as well as adhering to various rules and spatial data. This paper presents an integrated approach using Geographic Information Systems (GIS) and the Analytical Hierarchy Process (AHP), based on Multi-Criteria Decision Analysis (MCDA), to select the most sustainable MSW disposal site in Kanchanpur district, Nepal. Criteria for site selection were derived from existing literature, including residential proximity, roads, water bodies, slopes, elevation, and national parks. GIS was used to develop criteria maps, and AHP was employed for pairwise comparison and normalization to assign weights to the criteria. The weighted overlay tool in ArcGIS was then used to evaluate the weighted criteria maps, categorizing the site suitability into five classes: “extremely suitable”, “considerably suitable”, “moderately suitable”, “slightly suitable”, and “restricted”. The suitability map identified the most suitable areas for waste disposal, with "extremely suitable" areas being ideal for immediate use, and "considerably suitable" areas offering potential for future development. This method demonstrates the effectiveness of integrating GIS and AHP for sustainable solid waste management site selection in challenging environments like Kanchanpur district.
