ABSTRACT

 

Singrauli coal field situated in central India is managed by the Northern Coal fields Ltd, (NCL), and contributes 13% of India's coal production through mechanized opencast mining. With the availability of power grade coal reserves and nearby water reservoirs it offers an excellent location for super thermal power plants (STPS), Aluminium plants, and cement industries. In an area like Singrauli coal field, where large scale opencast mining is going on continuously, land use/land cover studies are of vital importance. The present study utilizes multi- spectral/multi-temporal data of Indian Remote Sensing Satellite (IRS) geocoded False Colour Composite (FCC) of 8th May 2001 and 4th May 2010 for land use/land cover mapping. Survey of India toposheet 63L/12 on scale 1: 50,000 were used to derive the base map which was overlaid on the FCC for land use/land cover mapping through visual interpretation method. Interpretation of satellite data led to the identification and delineation of 14 land use/land cover categories such as dense forest, open forest, open scrub, cultivated land, uncultivated land, mining pit, overburden dumps, wasteland and settlement. Ground truth verification was conducted in key areas. The comparative analysis of land use/land cover derived from 2001 and 2010 data shows that loss off dense forest area are due to the expansion of coal mining activity. Open scrub area has increased from 29.82 km2 in 2001 to 42.45 km2 in 2010 due to the plantation activities undertaken by the NCL, Overburden dumps area have increased from 30.4 km2 in 2001 to 39.44 km2 in 2010 as a result of expansion of coal mining areas, settlement area has also increased from 39.72 km2 in 2001 to 44.82 km2 in 2010, whereas area of cultivated land has decreased from 104.54 km2 in 2001 to 92.61 km2 in 2010. The drivers for land use/land cover change are mainly coal mining activities and industrial expansion, which have changed this belt into one of the prominent industrial zone in northern India. It has also been observed that the overburden dumps have been reclaimed under operation operation "Green Gold" launched by Northern Coalfield Ltd, through plantation activities.
