Abstract

Assessment of land utilization pattern is fundamental for managing and protection of natural resources of a region and the information on the existing landuse is one of the key pre-requisites for suggesting optimum use of a terrain. The use of Remote Sensing (RS) and Geographic Information System (GIS) can be helpful for quick and efficient landuse mappingthat provides the essential data necessary to undertake the inventory of a land. The present paper focuses on the assessment of land utilization pattern in the Pochampalli taluk of Krishnagiri district, Tamil Nadu. The study area geographically lies between 78o 13’ & 78o 29’ E longitudes and 12o 15’ & 12o 28’ N latitudes. The areal extent of the study area is about 1153 sq km.IRS LISS image acquired during the year 2015 was subjected to supervised clustering analysis and resulted output was validated with field inputs. Further, secondary data was used for change detection analysis. The results show that there has been a drastic decline in forest cover and increase in agricultural and horticultural land in the study area. The study clearly indicates that the major livelihood generationis through cropping.
