ABSTRACT

 

In recent years, the Environment becomes major concern for the human survival across the countries. Now-a-days intellectuals, academicians and environmentalists put their concern at all platforms for betterment of society. A systematic and multidisciplinary approach of mapping, monitoring and controlling the impact caused by the mining activities is necessary so as to understand the character and magnitude of these hazardous events. This paper presents the spatial extent, magnitude and temporal behavior of opencast sandstone mining areas and land use land cover (LU/LC) changes around Jodhpur city, Rajasthan,India due to increasing population and urbanization in the past one decade (2002-2012). Satellite data of IRS-P6, Cartosat and GeoEye was used to carried out the change detection and preparation of GIS based outputs maps of opencast mining areas and Environmental Impact Analysis (EIA) of the study area. The analysis indicates that unscientific and non-mechanized methods in opencast mines pose threat to the environment, life and degradation of nearby land area. Results revealed significant changes in mining areas, LU/LC, vegetation cover and with changes categories like no change, positive change and negative change. Results were also verified using ground truth data.
