area. Natural regeneration of forest species in the moderately
dense forest and afforestation in degraded forest and thin
forest areas should be taken up to reduce the runoff and soil
erosion from summits/ plateau and escarpments. The
drainline treatment viz. gully plugging, check dams,
spillways and other suitable engineering structures are
necessary to conserve rain water. The foot slope and alluvial
plains which are mostly under cultivation, hence field
treatments such as vegetative bunds, strip cropping mulching
and ploughing across the slopes are suggested. Green
manuring and and FYM should be encouraged to increase the
production of these soils. Climatically adopted fast growing
tree species should be planted on wastelands with or without
scrub lands to check the soil erosion.
4. CONCLUSIONS
From this study, it can be concluded that (i) Interpretation of
multispectral IRS-1C LISS-III supported by adequate field
checks is helpful for faster mapping and monitoring of
natural resources and (ii) Geographical Information System
(GIS) is a useful tool for storage and retrieval and integration
of spatial data for deriving information for soil erosion
assessment.

Based on soil characteristics, physiography, land use/ land
cover and soil erosion class, different vegetative and drainline
treatments were suggested for soil and water conservation in
