Abstract

The focus of this research is to distinguish between shifting land-use patterns and their geo-environmental implications in Simhadripuram Mandal, YSR Kadapa district, Andhra Pradesh, India. While the terms Landuse and Landcover (LULC) are sometimes used interchangeably, they have distinct natural meanings. Landuse refers to the function of a piece of land, such as mining, agriculture, or habitation. Landcover refers to the ground's surface cover, which might include vegetation, water, barren soil, and so on. Landuse is a notion that has a lot of qualities. It refers to people's actions on land that are directly related to the land. Landcover, on the other hand, refers to the vegetation that covers the surface of the land. The changes in LULC in Simhadripuram Mandal during the last ten years were studied using satellite imageries. LULC changes have been mapped using remote sensing and GIS modeling. The study is characterized in to five classifications, they are vegetation, fallow land, barren land, waterbodies, and built-up-land. The results reveal from 2009–10 to 2019–20, waterbodies are slightly increased from 2010 to 2020, is 9.29 km2. Vegetation is increased positively for the past decade to 25.16 Km2. The unirrigated land has been decreased to 27.1 km2. Built-up-land is increased from the last decade; it is noted as 22.77 km2. Fallow land has been decreased to 30.12 km2.
