The analysis of the impact of climate change on the cryosphere of Ugam Chatkal National Park, Bostonliq district, Uzbekistan, during the post-soviet period with remote sensing and statistical analysis

Abstract

This study investigates the impact of climate change on the cryosphere of Ugam Chatkal National Park in Uzbekistan's Bostonliq district, focusing on the period following the Soviet Union's dissolution. Utilizing remote sensing data and statistical analyses, including the Mann-Kendall test and Sen's slope calculations, the research assesses trends in snow/ice cover, glacier extent, and vegetation health through NDVI, NDSI, NDGI, and NDSII mean indices. Findings indicate a significant decrease in snow/ice cover and alterations in glacial features, underscoring the profound effects of climate warming on the region's water resources and ecological balance. The analysis highlights the urgency of implementing adaptive management strategies to mitigate these impacts, ensuring the sustainability of water supply and the preservation of biodiversity in Central Asia's vulnerable mountain ecosystems.
