Assessment of Land Use Land Cover Patterns and Impacts: A Case Study from Cuddapah Basin, India
Keywords:Veerupanayini Palli, LULC map, Drainage Map, Lithological map, ASTER Data, Spectral signatures.
The present study focuses on the digitization of LULC patterns of the Veerupanayini Palli Mandal, Kadapa district, Andhra Pradesh, India which is witnessing the rapid growth of urbanization, industrialization, and sustainable increase in population. This work is considered to be the first of its kind in the study area, which assists as baseline data to the policymakers and decision-makers, to utilize the natural resources viz., water, land, soil, cropping patterns, forest cover, etc., for sustainable development. Thematic maps like drainage maps, land use/land cover maps, lithological maps, etc., were generated by using satellite imageries coupled with adequate ground checks. This study falls under level IV of Anderson classification. The total area of the region is 293.64 sq.km. Results showed that the barren land/wasteland occupies a lion’s share in area wise followed by agricultural lands. The water bodies in the study area exist at a very low percentage. So, to have a better understanding of controls of hydrological conditions, lithological and drainage maps were generated by using ASTER data spectral signatures. It is found that most of the area comprises of purple shale with volcanic flows that produce the dendritic drainage pattern (tree-like branching).
