Nepal’s adventure tourism industry is facing cancellations and weaker bookings after glacial collapse and flooding along the Nepal-Tibet border killed 987 people and left nearly 4,250 missing, authorities said Tuesday. The disaster struck on Aug. 26 after a massive collapse of ice and rock in northern Nepal sent meltwater and debris into valleys, damaging roads, bridges and hydropower facilities. Tourism operators are warning of a sharp hit ahead of the peak travel season from Sept. 15 to Nov. 15, with Kathmandu’s Wander Thirst hostel forecasting maximum occupancy of 60%, compared with 100% last year. Nepal estimates rebuilding costs at $4 billion-$5 billion, while the disaster has renewed warnings about climate change, glacial hazards and the need for more resilient tourism infrastructure. Nepal has also sought urgent assistance from a special U.N. climate fund; the fund has received $820 million in pledges against requests from at least 119 countries totaling $2.8 billion.
