False colour composite (FCC) of IRS-P6 LISS IV geocoded data was interpreted in
conjunction with survey of India (SOI) toposheet on 1:50000 scale to extract information
on existing land use/ land cover, slope, aspect and physiography for characterization
and mapping of soils in the cluster village Tahakapal, Block-Tokapal, Dist.-Bastar
(Chhattisgarh) under NAIP-3 project. The revenue maps of 1:4000 scale was digitized
and converted to vector shape fle with attributes of feld details like owners name
& caste and coverage area, perimeter etc. This revenue map was overlapped to the
FCC of mosaic satellite data for retrieving the true land characterization of the project
area. Five farming situations were characterized and mapped as per the local names of
the agro climatic zone viz. Badi, Marhan, Tikra, Mal and Gabhar. The badi (10.7%)
comprises of upland settlement, marhan (40.5%) is the upper upland, tikra (17%) is
the lower upland, mal (16.1%) comprises the midland part and gabhar (15.7%) is
the low lying situation. Marhan are un-bunded with steep sloped situation. Tikra is
the un-bunded upland entisols with steep slope. Mal, the midland, is characterised as
Inceptisol, Alfsol, bunded, fat lands and Gabhar, the lowland, comprises of bunded,
Alfsol/ Vertisol supports crops like long duration paddy in Kharif followed by gram,
linseed, pea in Rabi. Additional water resources in the shape of shallow dug well and
farm ponds were constructed following the drainage line of the area. Site specifc land
use have been suggested and demonstrated with suitable soil and water conservation
measures for sustainable land resource management.

1. Introduction
Land resources are under intense pressure due to ever
increasing human and livestock population as well as over
exploitation, resulting in acceleration of soil degradation
(Velayuthum and Bhattacharya, 2000). The per capita land
availability is reducing and by the end of 2025, only 0.1 ha
will be available (Sarangi et al., 2005). Water is also rapidly
failing with unregulated over exploitation of ground water.
Statistics on water budget indicates that our country gets about
400 mham of precipitation annually, out of which 200 mham
are lost in evapotranspiration. About 135 mham is available
on the surface and remaining portion of precipitation joins
groundwater through percolation (Sharma and Paul, 1998).
As per estimate about 92 mham of the available surface water
ultimately goes to the seas despite of constructions of large
dams, reservoirs, check dams, water harvesting structures etc.
(Sharma and Paul, 1998). The soils and farming situations differ
in their morphology, physico-chemical characteristics, inherent
productivity and fertility and their response to management
practices vary accordingly. Thus, it is imperative to study the
soils and farming situations of a particular area for sustainable
land use. Due to their infuence on many of the environmental
issues both direct and indirect, such as loss of biodiversity,
changes in hydrological, carbon and nitrogen cycles, and
climate change (Vitousek, 1994; Schilling et al., 2010; Gao
et al., 2010), it is important that the areas under different
land use land cover (LULC) be categorized for adapting
suitable management strategies. Improper practices of LULC
including deforestation, uncontrolled and excessive grazing,
expansion of agriculture, and infrastructure development are
deteriorating watershed conditions (Bishaw, 2001), at various
temporal and spatial scales (Bisht and Tiwari, 1996). Farming
situation comprises of similar conditions of soil type and
land use land cover with acute correlation to the land slope.
The topography is bifurcated in fve local farming situations
which was distributed mainly based on soil, land use and slope
criteria. The spatial variability of felds is generally overlooked
