GEOMORPHIC ASSESSMENT OF THE PROBLEM OF LAND DEGRADATION AFFECTED BY HUMAN ACTIVITIES USING LANDSAT ETM +7: A CASE STUDY OF LONAR CRATER LAKE, INDIA Authors: Atul M. Jethe* And Lalit M. Thakar
ABSTRACT
The Lonar crater (diameter as 1830 m) is a simple impact crater in basaltic target rocks (Deccan
Traps). In the present research paper geomorphic assessment was done for the Lonar impact crater
lake. Therefore Remote Sensing and GIS technology have been effectively utilized. Now a day’s it is
an emerging technology to solve various geomorphic problems. As for Lonar crater is concern
various hygienic activities are carried out by the local people in the freshwater spring. The nuisance
of tourists; untreated domestic water and garbage are thrown from the city surrounded at the crater
rim. The ejected cover extending outward from the crater's rim has progressively been brought under
cultivation, the crater lake has a continuous cover of alluvium of silt to clay grain size around the
saline lake. The ejecta blanket of the crater degrading very fastly since from the last four to five
decades. So the present research paper provides RS and GIS techniques applications utilised in the
assessment of the problem of degrading lonar crater it also assesses the environmental issues and
ecological imbalance of the Loanr crater. Neither any technique nor any plan has been prepared for
the Lonar crater conservation. Most of the observations were made during the recent fieldwork by the
authors.
