International Mountain Day 2025, commemorated on 11 December, draws attention to the indispensable role that mountains play in safeguarding ecological balance and human prosperity. This year’s theme, ‘Glaciers Matter for Water, Food and Livelihoods in Mountains and Beyond,’ highlights glaciers as vital freshwater reserves for nearly two billion people, particularly Indigenous communities that depend on them for agriculture, hydropower, and cultural traditions. To mark the occasion, the Institute celebrated International Mountain Day 2025 by hosting a special lecture by Dr. Lavkush Kumar Patel, who is currently serving as a Scientist ‘D’ at the Centre for Cryosphere and Climate Change Studies (C4S), National Institute of Hydrology (NIH), Roorkee, titled ‘Understanding Glacier Dynamics: From Ice Flow to Climate Change.’ Prizes for the Photography Contest were also distributed among researchers and scientists.
