The Himalayas are vital to South Asia’s water and weather systems, feeding major rivers and shaping monsoon patterns. Cryospheric studies—focused on glaciers, snow, and ice—help us understand these dynamics and their impact on ecosystems, terrain stability, and natural hazards like avalanches, landslides, and glacial lake floods (GLOFs). This research is essential for disaster risk reduction, water security, and sustainable development in vulnerable mountain communities. As a multidisciplinary field, cryospheric science bridges hydrology, geology, climate science, and ecology.
