are sanctioned, covering 7 blocks, in 46 villages, of an area
sanctioned 23,500 ha. Under Haryali-II, 50 projects were
sanctioned in 8 blocks of Barmer District, covering 50
villages, in about 2,500 ha. Under Haryali-II Special,
sanctioned projects were 50 in all the eight blocks and
spread out in about 77 villages, for an area of 25,000 ha. In
the Jaiselmer district,under Haryali-II Special, the
programme was implanted in 3 blocks, in 38 villages,
covering 20,000 ha. In Bhilwara district, under IWDP-12th
Phase, in one block, 11 villages, covering an area of 5,806
ha and under IWDP-9th Phase, in one block, covering
4,800 ha, was implemented.
The evaluation for all the villages where the watershed
programmes were implemented was undertaken for GIS
based evaluation by using satellite imageries and GPS
based data.
The multi season satellite data was procured for the study
area from the National Remote Sensing Centre (NRSC),
Hyderabad for preliminary analysis. The analysis was
validated with field survey of each structure and GPS
coordinate data. Field photographs and legacy data was
collected for augmenting the detail analysis. Extensive field
surveys of the watersheds was carried on during last two
weeks for validation of the satellite data for precise analysis
and evaluation.
2. OBJECTIVES OF THE STUDY
The overall objective of the study was to develop an
operational kit of remote sensing technology applicable at
different levels of planning for watershed evaluation by
using suitable satellite data products. The assessment of
condition of vegetation is one of the indicators of
environment. The quality and quantity of natural vegetative
cover, biodiversity, forest fire, plant disease etc., are some
of the areas of interest that are readily studies using remote
sensing.
3. STUDY AREA
The study area consist of Thirtiy four villages Borala,
