APPLICATION OF GEOSPATIAL TECHNOLOGY AND ANALYTIC HIERARCHY PROCESS (AHP) FOR MUNICIPAL SOLID WASTE LANDFILL SITING AT NASHIK CITY,INDIA.

Abstract

The rapid increase in global waste generation necessitates the identification of suitable landfill sites to mitigate environmental impacts. This study employs a scientific approach to determine optimal landfill locations in Nashik, India, using Geospatial Analysis and the Analytic Hierarchy Process (AHP). By integrating Geographic Information System (GIS) technology with AHP, the study evaluates morphological, environmental, and socio-economic factors crucial for landfill siting. Data from online portals, government institutions, and recent waste production records from the Regional Environmental Office were analyzed. Expert judgement was applied to 13 criteria for landfill site selection, ensuring a comprehensive assessment. The findings reveal that 9.78 hectares are very highly suitable 10.87 hectares are highly suitable, and 4.14 hectares are moderately suitable for landfill sites, while the remaining areas are unsuitable. This research aims to support sustainable waste management policies and assist stakeholders in making informed decisions to reduce environmental impacts.
