6. INDIAN EXPERIENCE
Having realised the importance of integrated
approach for sustainable development, the
Department of Space, Government of India in
collaboration with the State Governments had
initiated pilot studies in 21 districts covering
203,000 sq. km. and representing diverse terrain,
agro-climatic conditions and social and cultural
practices apart from very often affected by drought,
in the year 1987 to find scientific and lasting
solution to mitigate drought following the
unprecedented drought in many parts of the country
during the period 1985-87. Based on encouraging
results of the pilot projects, such study was
extended to another 153 districts covering 549,496
sq. km. spread over in 25 states at the instance of
Planning Commission, Govt. of India - the highest
policy decision making body, under a national
project titled "Integrated Mission for Sustainable
Development (IMSD)". A conceptual framework of
IMSD is given in Fig. 1. For ease of implementation
of the action plan in phased manner in these
selected districts, initially it was decided to identify
a priority block in each district for the study. (A
block is an administrative unit covering an area
ranging from 1000-1500 sq. Km.). Subsequently, 80
blocks spread over in 80 districts covering 85,339
sq. km. have been selected on a priority basis for
taking up such study.
6.1 Data base
For generating information on land and water
resources, the Linear Imaging Self-scanning (LISS-
Il) data from Indian Remote Sensing Satellite (IRS-
1A/1B) in the form of False Colour Composite
(FCC) prints at 1:50,000 scale and digital data
(Computer Compatible Tapes) have been used in
conjunction with ancillary information, namely
published reports, thematic maps, etc. and
adequate field check. Information on slope has
been derived from 1:50,000 scale Survey of India
topographical sheets. For appreciation of ciimate of
the area, meteorological data available with the
India Meteorological Departmentrespective district
or taluk (an administrative unit) headquarters have
been made use of. Besides, information on
demographic and socio-economic conditions has
been taken from the published records by the
concerned departments.
6.2 Approach
The holistic approach essentially involves
generation of thematic maps on land and water
resources and their integration with the socio-
economic data to arrive at locale-specific
prescription for land and water resources
development. Various steps involved are described
hereunder :
6.2.1 Generation of Thematic Maps
Thematic maps on hydrogeomorphological
condition, soil resources and present land use/land
cover have been generated through systematic
visual interpretation and/digital analysis of IRS-IA/B
LISS-II multispectral data (with 362/5m resolution)
in conjunction with the collateral information
supported by adequate ground truth. The
information derived on lithology of the area and
geomorphic features therein was used to infer
ground water potential of each lithological unit
based on geomorphic features and recharge
conditions. Soil resources map of the area have
been prepared by delineating sub-divisions within
each geo-morphic units based on erosion status,
land use/land cover and image elements, namely
colour, texture, shape, pattern, association, etc.
Soil composition of each geomorphic unit was
defined by studying typical soil profiles in the field
and classifying them upto series level according to
Soil Taxonomy (U.S. Department of Agriculture,
1994) based on morphological characteristics and
chemical analyses data. In addition, derivative
maps, namely land capability and land irrigability
maps were generated based on information on soils
and terrain conditions based on criteria laid down
by All India Soil and Land Use Survey Organisation.
Besides, land use/land cover maps have been
prepared using monsoon (kharif) and winter (rabi)
crop growing seasons and summer period satellite
data, and single-cropped and double-cropped
areas apart from other land use/land cover
categories have been delineated. Furthermore,
micro watersheds and waterbodies have been
delineated and the drainage network have also
been mapped.
Slope maps showing various slope categories have
been prepared based on contour information
available at 1:50,000 scale topographical sheets.
Road network and the location and extent of
settlements have also been taken from
topographical sheets. Rainfall, demographic and
socio-economic data were analysed to generate
information on population density, tribal population,
literacy status, economic backwardness and the
availability of basic amenities.
6.2.2 Generation of Action Plan
The generation of action plan essentially involves
careful study of thematic maps on land and water
resources both individually as well as in
combination to identify various land and water
