The land use pattern of a sub watershed is an outcome of both natural and socio-economic factors and their utilisation by population in time and space. Land is becoming a scarce commodity due to immense agricultural and demographic pressure. Change in land use is a dynamic process taking place on the surface and it becomes most important factor for managing natural resources. In the current study Remote Sensing technique is used to analyse the land use changes in Achalvadi sub watershed of Vaniyar river, Dharmapuri district, using remote sensing and GIS.
