Description Journal
Continual, historical, and accurate information
about the land use/land cover (LULC) changes of
the earth’s surface is extremely important for sustainable
management of natural resources. In this study, historical
topographic sheets, IRS P6 LISS-III, and LANDSAT
TM images were used to provide recent and historical
LULC conditions of the EasternGhats Highlands of east
India. The supervised classification results were further
improved by employing image enhancement and visual
interpretation. Ratio Vegetation Index with fuzzy-based
possibilistic c-means classification approach has improved
the classification accuracy of the shifting cultivated
area. Post-classification comparisons of the classified
images indicated that the major change consisted
of barren land and forestland changing into agricultural
land and scrubland. Between 1931 and 2008, forest
cover was decreased from 52.7% to 29.6% of total area.
There was an increase in the scrub area from 874
(10.4%) to 1269 km2 (15.2%), and agricultural land
from 978 (11.7%) to 2864 km2 (34.2%) during the same
period. The rate of deforestation was found to be
0.65 km2 per year for reserve forest and 24.50 km2 per
year for mixed forest. The shifting cultivated area in the
district was 308.7 km2 during 2004, and that has been
reduced since then and now is stabilized to 186.4 km2
area. Among this 186.4 km2 area, nearly half is covered
by abandoned shifting cultivation. The decadal rate of
decrease of shifting cultivated area is 0.15% per year.
The shifting cultivated areas were mainly distributed at
elevations 580–810 and 810–907 m and slopes 20–30
and 30–40%. Southeast and south facing slopes were
preferred for shifting cultivation. Based on the identified
causes of the change in shifting cultivation, policy recommendations
for their better management were made.
