Impact of coal mining on land environment in the western part of Jharia Coal field, Jharkhand, India - An analysis through Remote Sensing and GIS techniques

Wednesday, October 15th, 12:00 - 1:30 p.m. CGIS South building, Room S050. View the presentation slides.

Presenter: Dr. Lopamudra Dasgupta, of the GIS Research Laboratory, University of Washington.

Abstract:

Western Jharia Coal Field (JCF) has a long and diverse mining history, involving both underground and opencast mining, which is affecting the land environment and thus changing the land use pattern of the area. 

By preparing the Land Use Land Cover (LULC) maps of this area for the years 1987, 2000, 2004, 2007 and 2011, the change patterns of LULC classes for short term difference, i.e. 2000, 2004, 2007 and 2011 and also the change patterns of LULC classes for long term difference, i.e. 1987, 2000 and 2011 have been analyzed. The present study is an analytical study on the LULC change pattern of the western part of JCF, using time-series remote sensing data and integration of multi-theme data by the aid of Geographical Information System (GIS) techniques, applying Boolean Logic. 

AlsoLULC maps of the years 2015 and 2020 have been generated, where the percentage of each LULC class is displayed, showing a probable future trend of LULC for this area using Regression Equation and henceforth, suggesting suitable remedial measures for the adverse impacts on the land environment, affecting the society in the long run. 

LULC maps of the adjacent litho-units for the years 1987 and 2011, which are non-coal bearing and non-mining area, have also been prepared to make a comparative study between the LULC changing pattern of the mining and non-mining areas. 

A few studies have been taken place on the land environmental condition, primarily in the eastern part of JCF. But till date, attention is unfrequented to the western part of JCF regarding land environmental research as an impact of coal mining. This sort of analytical study is the very first attempt, on the LULC change pattern of the western part of JCF, using time-series remote sensing data and integration of multi-theme data by the aid of GIS techniques by applying Boolean Logic.

 The findings of the present study could be useful while formulating the future management plan for western part of JCF. It is understandable that for the economic growth of the region and to make proper use of the natural resources present over there, certain activities have to take place.  A proper land use planning by the policy makers is needed to arrest this tendency at an earliest.
