Land use and land cover change has become a prime issued in present scenario for managing natural resources and utilization of land. Dhanbad is the coal capital of India and the fastest mining area in India witnessing fast land use change in agriculture land, vegetation, open scrub and water bodies. This study reveals a dynamic land cover change in the study area due to sand and enhancement of agriculture land. Using the Landsat-5 TM images of Dhanbad District acquired in 1987 and 2011 classification was done. Land Use Land Cover change (LU/LC) is a dynamic process taking place on the surface and it became a central component in current strategy. Therefore, land use land cover change analysis is very important for environmental management. LU/LC helps to plan for future changes that may occur in that area and to taking decision to realize the effects of these changes. Decision makers also have to identify, what are the factors that affect the LU/LC change (such as population, agricultural growth etc.). the aim of this study to detect land use land cover changed during 1987 to 2011 using satellite images of Landsat-5 TM. Remote sensing and geographical information system technology are providing new tools for monitoring fast land use change. The massive changes of land use land covers are dense forest, low dense forest, open scrub, agricultural land, agricultural fallow, built-up, mining, river, water bodies, sand and barren land. The synoptic analysis revealed to the rapid increase in mining activity and degraded the forest land cover. The study was found that a phenomenal change in the mining areas, change in vegetation cover and change in built-ups land. The overall trend indicates considerable growth in the mining areas with increase in urban areas. Mining area shows the maximum change with an increase of 5% and as a result decreases in vegetation cover. The low dense areas and open scrub suffered decrease in area i.e. 1% and 2% respectively. The land is now converted into open cast and underground mining. The second major change noticed is the increase in built-up i.e. 2%, this resulted in decrease in dense forest covers. The dense forest cover gone through a tremendous change; with a decrease in 4% land cover. Rest of the land cover showed minor changes like water bodies increased up to 2%, reason may be seasonal variation or other. Certain land covers like river and sand shows no change.
