Application of Geoinformatics in Natural Resource Management at Micro Level
To demonstrate the application of geoinformatics in natural resources study, a Study was taken up in the Keshampet Mandal of Mahaboobnagar District of Andhra Pradesh and resource analysis was made for the entire study area with base information and through satellite imageries, the various analysis of which are presented below:

Recommedations for optimising the resource use
- As the major lineament zones form the important and promising horizons for
potential ground water deeper levels of the earth, proper identification of the
lineaments using remote sensing techniques (aerial & satellite images) followed by
ground checks would go a long way while selecting sites/areas for assured ground
water development.
- As the well irrigation is the main key in the study area, as the rainfall in the district
general erratic and irregular and the average annual rainfall is low. There is every
need to utilise as much of rain water as possible by improving the recharge condition
in the study area. This is possible by constructing the low-cost rainwater harvesting
structures such as percolation tanks, check dams/rivers and farm ponds.
- It is suggested to go for very high Silvipasture development, controlled grazing,
trenching and spoil banks to conserve moisture, plantation of arid horticulture species,
high silvipasture development, soil and water conservation on watershed basis, mixed
cropping, moderate or mixed and multiple cropping, drip & sprinkler irrigation, plant
population adjustment according to available moisture holding capacity, balanced
fertilization , low improved cropping pattern, weed control etc are recommended for
drought mitigation.
- BILWRU developed by the scientists of APSRAC , Recommended Optimal
Landuse and Farming Systems (ROLUFS) grouped into 12 classes were suggested
for the entire block with a map with each group shown in different colour.
