Disaster statistics from 1990-2012 Hindu Kush Himalayan region
The region has had an average of
76 disaster events each year.
On average, more than 36,000
people are killed and 178 million affected each year due to
natural disasters in the region.

Water-related hazards

Transboundary floods have greater impact on lives and property
Globally, 10% of all floods are transboundary, and they cause over 30% of all flood casualties and account for close to 60% of all those displaced by floods. Bakker, 2006
![Page 18: Importance, Key Questions on Resilience and Managing Disasters in the Hindu Kush Himalayas](https://reader036.vdocuments.us/reader036/viewer/2022070516/5873423a1a28abf21b8b74e7/html5/thumbnails/18.jpg)
Lack of information, little preparation
· 9 April 2000: Landslide blocked the Yigong River, a tributary of the Yarlung Zangbo (Brahmaputra) River
· Outburst on 10 June 2000 created a huge flash flood of up to 1.26x105 m3/s
· Extensive damage, but no casualties in China
· In India, heavy causalities - 30 dead - >100 missing - >50,000 homeless - damage of USD 22.9 million

Data sharing can save lives and property
· Data sharing agreement developed between India and China in 2002
· 22 June 2004: Landslide blocked the Pareechu River in Tibet (upper reaches of Sutlej River)
· Lake volume - 79,180,000 m3
· Chinese authorities communicated to their Indian counterparts well before and when the breach occurred
· 56 villages along the Sutlej from Kinnaur to Bilaspur were identified as at risk
· The dam burst on 25 June 2005· The direct cost of flood damage was an estimated
USD 200 million · There were no human casualties because of prior
communication from the upstream country
1 month after landslide
2.5 months after landslide

Lessons learned from disasters
· Data gaps
· End-to-end information systems
· Proper infrastructure planning
· Overarching need for transboundary cooperation
![Page 21: Importance, Key Questions on Resilience and Managing Disasters in the Hindu Kush Himalayas](https://reader036.vdocuments.us/reader036/viewer/2022070516/5873423a1a28abf21b8b74e7/html5/thumbnails/21.jpg)
Data gaps
• High-altitude monitoring stations are sparse• Limited transboundary data sharing
Monitoring station distribution

Conclusion
• Need for end-to-end information systems– Hi-tech to low-tech– Science to government to community
• Infrastructure planning– Identify risks and vulnerabilities
• Mountain specific planning• Transboundary information sharing
– Sharing mechanisms• Underpinned by regional cooperation
