Background and Purpose: Unscientific and unhygienic urban waste disposal practices can trigger significant environmental, health, and safety crises within a region. Therefore, it is crucial to assess the spatial suitability of landfill sites to mitigate these risks. This study aims to evaluate the current waste disposal site in Akhtarabad, Malard, aligning its suitability with both national and international standards.
Materials and Methods: This research adopts a descriptive-analytical methodology, utilizing a survey-based approach. The factors influencing spatial suitability were initially identified through various authoritative sources, including regulations from environmental organizations and the Minnesota Pollution Control Agency (MPCA) guidelines for waste disposal in the United States. The integration of these factors was conducted using the LINMAP (Linear Programming for Multidimensional Analysis of Preferences) method for multi-criteria decision-making and weighting. ArcGIS software was employed to analyze and overlay information layers. The prioritization of spatial suitability for urban waste disposal sites, along with the calculation of conformity percentages, was executed using the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method.
Results: The analysis revealed that among the evaluated criteria for spatial suitability, the distance from residential areas, educational and healthcare centres, urban centres, groundwater, and surface waters were the most heavily weighted. The Moran Index of 0.640034, coupled with the calculated standard score, supports the hypothesis of a clustered spatial suitability pattern with a 99% confidence level.
Conclusion: National criteria exert a more substantial influence on the evaluation of spatial suitability. The findings of this study indicate that the combination of LINMAP and TOPSIS is a reliable and effective approach for assessing the spatial suitability of urban waste disposal sites.
