Abstract
Land utilization is a key factor in the allocation and function of ecosystems. The limited available land is insufficient to satisfy the growing demand. Sustainable future depends on Human decisions on utilization of land. The landuse analysis between two time periods and their impact especially on sustainable development may leads to proper planning at different territorial levels. The present study examines spatiotemporal trends in modification of LULC (land use and land cover) changes in the Vijayawada area. Landsat 5 and 8 satellite imagery was used to produce change deduction maps over a sixteen year of time period (2005 and 2020). For the year 2005, 30 meter resolution Landsat 5 satellite image are used and for the year 2020 15 meter resolution Landsat 8 images are used to identify the changes in spatiotemporal trends. Maximum lilelihood supervised classification techniques are used to estimate land use and land cover change. The dynamics of LULC modification for 16 year time period and its impact were discussed as key findings in this paper. This study reports that, by using geo-spatial techniques could reduce the main causes of LULC change detection that threaten ecosystems and biodiversity through timely and adequate monitoring.
