Abstract
Our environment is facing potential threat from unsustainable waste disposal practices prevailing in almost all the urban centers in the country. A balanced development has always remained the main objective of any developmental strategy. Though the living standard has significantly changed, the method of public health and sanitation still remained primitive. Vast quantities of waste generation by the cities are one of the serious outcomes of unplanned development. Selection of suitable sites for waste disposal has been normally carried by traditional approaches i.e. throwing it at all types of vacant land in or around the city. Satellite Remote Sensing images can provide information about the wasteland and other associated features, which help in selection of sites. Coupled with GIS it can provide an opportunity to integrate field parameters with population and other relevant data. In the present study, we have selected Ranchi urban complex, which is the capital of newly created Jharkhand State. Population of Ranchi is increasing day by day due to its position as administrative nucleus, available resources, and job opportunities. At present there is no declared waste disposal sites in Ranchi. Ranchi Municipality Corporation (RMC) is disposing municipal wastes in the low-lying areas in general and drainage in particular causing nuisance. This paper aims at demonstrating the utility of Remote Sensing Technology in identification of wasteland, and assesses the capability of GIS Technology for site selection for waste disposal. It also explores the capabilities of GIS in determining an ecologically sound waste management programme. IRS-1C-PAN (5.8mspatial resolution) and LISS-III (23.5m spatial resolution) satellite data have been used along with S.O.I toposheets of Ranchi Municipal area using ARC/INFO GIS Environment and PCI Geomatica software. Different weights were assigned on the basis of instances to various parameters to select the suitable waste disposal sites. |
