Nepal seeks China's data sharing after devastating Himalayan flash floods

Nepal is calling for increased data sharing with China following a devastating flash flood on August 26 that cost the nation an amount equivalent to one-tenth of its annual GDP. The disaster, which occurred in the Himalayan border region, was likely triggered by a massive ice and rock avalanche. Experts suggest that a large ice mass may have broken off at an altitude of approximately 5,200 meters, falling vertically and melting as it swept tons of sediment down toward river valleys.

Reports indicate that Nepalese officials met with Chinese representatives in Kathmandu on May 27 to discuss enhancing cooperation on monitoring glacier-related hazards and weather risks. During these discussions, Nepalese delegates proposed joint measures such as mapping danger zones and creating ice lake inventories. However, Nepalese officials expressed frustration that they did not receive the level of detailed information regarding glacier movements and water levels they had requested from China.

While scientists note that such events have occurred historically, the unprecedented scale of this specific landslide has raised alarms. Experts point to climate change as a factor increasing the intensity and frequency of glacier melting, which heightens the risk of such catastrophic events in the region.
