Mining and human activities
impacted the natural ecosystem leading to land use/land cover (LU/LC) change is
of great concern by environmentalist and the society. The present study
evaluated the LU/LC changes due to exploitation of coal in Dhanbad district of
India during the period of 1987 to 2017. Remote sensing (RS) data indicated that
out of 2043.32 ha LU/LC comprised of dense forest, low dense forest, open
scrub, agriculture land, agriculture fallow, barren land, sand, river, water
body, built-up and mining, constituted percent values of 8.17, 3.11, 39.51,
18.88, 12.69, 1.25, 0.76, 3.12, 2.88, 4.40 and 5.22 in 1987 and 4.69, 6.01,
15.78, 41.36, 9.97, 3.90, 2.55, 2.22, 1.43, 7.91, 4.18 in 2017 respectively.
The LU/LC during 30 years indicated the percent share of dense forest, open
scrub, agricultural fallow, river, water body and mining decreased by 42.63,
60.45, 21.47, 28.80, 50.37 and 19.85 % respectively.
Land use changes were due to harvesting of forest for fuel, shelter and
agriculture, construction of residential houses in fallow land, urbanization
and sand removal for construction material. The increase in low dense forest,
agricultural land, barren land, sand and built-up area by 93.38, 119.06,
211.63, 234.96 and 79.85 percent respectively were due to shift of land use
from forest to open scrub, agricultural fields and barren lands, new settlement
by utilizing sands from river banks making the river stretch wider, open mine
pits converted into water bodies in the district. These resulted in a
considerable change in land use pattern in Dhanbad district, Jharkhand, India.
