ABSTRACT: Change analysis acquires effective information in the form of maps and
statistical data which becomes the central component in spatial planning,
monitoring environmental changes, management and utilization of land. The
present study makes an attempt to assess the changes in land use land cover
using multi-temporal satellite data in south-east Rajasthan. These maps were derived from
geocoded dia-positive False Color Composites (FCC’s) of IRS 1991, 2001, 2010
& 2018 using Arc GIS platform. The present study demonstrates the
extension, approach and result of change analysis which might be helpful for
decision making and sustainable growth. The landscape has been divided into 12
categories. Mining and its associated features were increased whereas forest
and open scrub cover shows decreasing trend during the study period. The former
increased by 23.82 km2 while the later shrunk by 26.08 km2.
Most significant changes are also witnessed in settlement and industrial areas which shows increment by 8.8 km2 and 1.33 km2. Stone
quarrying has destroyed arable land, natural vegetation cover,
topsoil, subsoil and consequently the soil profile of the area. On the other
hand cultivated land is increasing due to the conversion
of uncultivated land and scrub cover with facilitation of
irrigation and modern agricultural activities under different government
schemes. The study shows that the area of 184.88 km2 has undergone significant spatial and
temporal changes during the study period.
