## Key points

- At least 300,000 people may be in Himalayan disaster risk zones.
- Built-up land in studied high-risk areas rose 45% from 2016 to 2023.
- Researchers say development near rivers and glacial lakes could deepen exposure.

## Summary

A new study suggests at least 300,000 people in parts of the Himalayas may live in areas exposed to flooding and other disasters, as construction has expanded in high-risk zones. The findings matter because tourism, housing and infrastructure are growing near rivers and glacial lakes, potentially increasing the number of people and buildings at risk.

Researchers found built-up land in the areas they examined grew by about 45% from 2016 to 2023, rising almost 78% in zones particularly threatened by glacial lake floods. The study covered parts of northern Nepal, south-eastern Tibet and India’s Uttarakhand, including areas up to 50km downstream of rivers and around 1,360 glacial lakes; the researchers say neighbouring areas may also face danger. Recent floods and landslides have damaged homes and bridges, while officials and tourism operators describe the challenge of managing development near rivers.
