REMOTE SENSING TECHNIQUES FOR LAND USE MAPPING IN LOWER AGAR SUB WATERSHED, CHHATTISGARH, INDIA
Keywords:
utilisation, commodity, dynamic, technique, resourcesAbstract
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 Lower Agar sub watershed of Chhattisgarh. Result shows the change that has been occurred during 2000 and 2009 as agriculture land with crop cover in the sub watershed increased from 24.6% to 32.25% of the total area whereas barren land reduced from 28% to 19.2%. The land use change index ranges observed 1.15 to 8.46 for water bodies and rural settlement in this period in the sub watershed.
