Climate change has significantly impacted India's water resources, affecting rainfall patterns, river flows, groundwater levels, and overall water availability. Rising temperatures, erratic monsoons, and glacier retreat in the Himalayas have exacerbated water scarcity and increased the frequency of droughts and floods. This study explores the role of GIS and remote sensing technologies in assessing and managing these climate-induced changes. By analyzing satellite imagery, hydrological models, and spatial data, GIS provides insights into river basin dynamics, groundwater depletion, and land-use changes, enabling better decision-making for water conservation. Case studies on major river basins like Ganga, Brahmaputra, and Godavari highlight the practical applications of these technologies. The paper also discusses government policies and adaptation strategies to mitigate climate risks. Integrating remote sensing with sustainable water management practices is essential to ensure India’s long-term water security and resilience against climate change.
