Recent flooding in Nepal has renewed attention on the dangers facing Himalayan valleys, where melting ice, unstable slopes and extreme weather can combine to produce destructive floods.

The impact could extend far beyond the mountains. Himalayan rivers provide water for millions of people across India, Nepal, Bhutan, China and Pakistan, supporting agriculture, communities and hydropower.

Experts say stronger glacier monitoring, early-warning systems, satellite technology and better cooperation between Himalayan countries will be increasingly important. The changing Himalayas are becoming not only a climate concern, but also a major issue for Asia's future water and disaster security.
