SHIFTING LANDSCAPES: UNRAVELING TIRUPATI'S TRANSFORMATION THROUGH SATELLITE INSIGHTS

Abstract

The transformation of Tirupati's landscape over the past two decades reflects the dynamic interplay between urbanization, agricultural expansion, and environmental degradation. Through a comprehensive analysis of land use and land cover (LULC) changes using satellite imagery and spatial analysis techniques, this study offers insights into the evolving socio-environmental dynamics of the region. The findings reveal significant increases in built-up areas and corresponding declines in agricultural lands and natural ecosystems, driven by population growth and economic development. Despite efforts to mitigate environmental degradation, challenges such as soil erosion, deforestation, and water scarcity persist. However, there are promising initiatives aimed at enhancing water security and ecosystem resilience. In statistical terms, the analysis of land use and land cover changes in Tirupati reveals compelling trends over the study period. Utilizing Landsat satellite data and Maximum Likelihood Estimation (MLE) techniques, significant shifts in urbanization, agricultural activity, and environmental degradation were quantitatively assessed. The results demonstrate a remarkable expansion of built-up areas, accompanied by a concerning decline in agricultural lands and natural vegetation cover. Moreover, buffer ring and directionality analyses elucidate spatial patterns of change, highlighting the concentrated urban growth in specific directions and the widespread degradation of natural habitats. These statistical insights underscore the urgency of implementing sustainable development strategies and conservation measures to address the socio-environmental challenges facing Tirupati and foster long-term resilience. The study underscores the importance of sustainable development strategies and conservation efforts to address these challenges and ensure the long-term sustainability of Tirupati and its surrounding areas.
