WASTELAND AND FOREST IN SOUTH-EAST DRY AGRO-CLIMATIC ZONES OF KARNATAKA USING REMOTE SENSING AND GIS TECHNIQUES.

Forest is important source of biodiversity in the study area forest are spreading all over the area we are comparing to forest with wastelands we know that where the Granitic is present where wasteland is developed overall studying about forest in study area highest forest coming under the kanakapura region , North of Tumkur and southern part of Chitradurga Remote sensing (RS) is an efficient and cost-effective means of monitoring landscapes. One of the key challenges in the RS study is to improve the accuracy of classification. The present study aims to propose appropriate the Major identifiable wasteland categories are barren rocky; land with scrub; mining wasteland and salt affected area. The final result specifies each wasteland categories in the study area using GIS technique considering the environmental, biophysical and socio-economic factors.
