Changes brought in Land use due to anthropogenic factors on the nature have posed serious threat to Environment. Land use / Land cover dynamics and its effects on ecological and hydrological process and on human livelihood has constituted major concerns today, evident from the consideration of Land use / Land cover change as an important driver for climate change. Land use change is a locally pervasive and globally significant ecological trend. An attempt has been made to study the changes in the land use pattern of Bobbili mandal. Comparative analysis of maps of two-time period can provide authentic data with respect to changes brought in the Land use pattern. For detection of temporal changes in the land use pattern two period data sets i.e., IRS LISS III 1999-2000 and 2009-2010 are used. The geospatial tools have been used to assess the changes in land use / land cover. The detailed analysis have revealed that the area under agriculture is decreased and built up land increased from 3.19 to 4.13%. The generated information for the land use pattern will aid in understanding the spatial distribution and extent which will ultimately help in further planning and taking in time appropriate decisions for sustainable development.
