Abstract
The land use/land cove (LULC) patterns of a region is an outcome of natural and socio – economic factors and their utilization by ma n in time and space. Land is becoming a scarce resource due to immense agricultural and demographic pressure. Hence, information on LULC and possibilities for their optimal use is crucial for the selection, planning and implementation of land use schemes to meet the increasing demands for basic human needs and welfare. This information also assists in monitoring the dynamics of land use resulting out of adjusting demands of accelerating population. Therefore, the present study is made to detect the land use/ land cover change between 2005-06 and 2015-16 for the Thadipudi Reservoir Catchment of Visakhapatnam and Vizianagaram districts, Andhra Pradesh, India using geo-spatial technologies. Landsat TM data for the year 2015 and IRS-1D-LISS-III data for the year 2015 have been used for extraction of thematic information on the analysis of land use/ land cover change detection.. After drawing the maps and Graphs of Change detection, We concluded that the Varied Land use Land cover patterns like Agricultural Land-Cropped in two Seasons consists of 5.02% in 2005-06 and it had been changes to 4.17 % in 2015-16, Waterbodies-Reservoir/Tanks-Permanent consists of 2.69 % in 2005-06 and it absolutely was changes to 0.09% in 2015-16, Waterbodies-River/Stream-Non Perennial consists of 0.66% in 2005-06 and it had been changes to 0.02% in 2015-16 & Waterbodies-Reservoir/Tanks-Seasonal consists of 0.93% in 2005-06 and it had been changes to 3.54 % in 2015-16. During this study, we use the ARC GIS software version 10.2.2.1 for the Land use and Land cover change detection in Study area and find the varied changes in the patterns as explained above. The symptoms of LULC manifest because the current global environmental concerns like increasing concentrations of greenhouses gases within the atmosphere, loss of biodiversity and conversion and fragmentation of natural vegetation areas. Human activities like agriculture and mining strongly influence the hydrological cycle because of the alterations in infiltration, overland flow and or evapotranspiration as they cause changes in land-use.
