ENVIRONMENTAL CHANGE DETECTION IN ADOLA GOLD FIELD
USING REMOTELY SENSED DATA AND INDICATOR BASED APPROACH

ABSTRACT
This research enabled to map, detect and quantify environmental changes in the Adola Gold Field using multi temporal records of remotely sensed data and field survey.
For the change detection and analysis purpose three periods, the late 1960s, the early 1970s and the contemporary situation using the late 1980s records, and field survey up-date were used. The integrated approach to detect and quantify the environment change revealed that big changes on the vulnerable environment has taken place after the 1980s, with the beginning of the intensive mining and farming activities following a change in land policy. Deforestation and landscape change and consequential environmental quality deterioration as a result of intensifying mining and agricultural activities and intensive small urban centres growths are the main environmental changes that took place mainly in the recent two decades. The geomorphological setting and the land use and land cover of the study area are some of the elements those will aggravate more environmental degradation.
In this research an overview of the environmental, geological and geomorphological processes are indicated, environmental changes are shown both qualitatively and quantitatively.
