Evaluating the Impact of Climate Change on Freshwater Resources: A Remote Sensing Approach for Global Water Scarcity Assessment

Abstract

Climate change poses a significant threat to freshwater resources worldwide, exacerbating issues of water scarcity and challenging the sustainability of ecosystems. This article evaluates the impact of climate change on global freshwater availability by employing a remote sensing approach to assess water scarcity. By analyzing satellite data, including information on precipitation patterns, soil moisture, and surface water bodies, this study offers a comprehensive view of how climate-induced changes affect freshwater distribution. The remote sensing techniques provide spatial and temporal insights into the decline of freshwater reserves in critical regions, particularly those already vulnerable to drought and over-extraction. The article highlights case studies in regions such as sub-Saharan Africa and South Asia, where water scarcity has intensified due to rising temperatures and altered rainfall patterns. In addition, the study explores the role of satellite imagery in forecasting future water availability trends and helping policymakers develop sustainable water management strategies. The findings underscore the need for global collaboration in addressing the looming crisis of water scarcity, emphasizing the importance of integrating climate models with remote sensing data to inform resource management. This research contributes to the growing body of knowledge on how climate change affects water resources and provides practical solutions for mitigating the challenges of global water scarcity.
