Site Suitability Analysis for Municipal Solid Waste Disposal in Mangalore City Corporation, Karnataka - Using Geospatial Technology

Solid waste dumping is a challenging issue now-a-days in urban extent. The solid waste produced in municipality areas (ULB) of Indian cities which impacts on health as well as the surrounding environment. The first requirement to dumping urban solid waste in our Indian cities is a suitable land site.

The objective of present study was the urban solid waste dumping site selection using the geospatial techniques for Mangalore City Corporation area. Remote Sensing and GIS multi-criteria analysis (MCA) methods were used to identifying the suitable site for disposal urban solid waste. Landsat ETM+ and SRTM DEM data were used for present paper. Estimation of buffer distance analysis and overlay weightage procedure was used for this study. The finding result has been indicates that only 6.45 km2 (3.93 %) area is suitable for solid waste dumping, otherwise 17.289 km2, 77.31 km2 and 62.95 km2 area are fall under unsuitable, less suitable and moderate suitable with 10.54 %, 47.13 % and 38.39 % respectively.
