TRANSCRIPT
Regional flood information system and Cryosphere Monitoring
in the Hindu Kush Himalaya
Mandira Singh Shrestha
ICIMOD
South Asia Hydromet Forum, 18-21 September 2018
Geneva
Outline of presentation
• The Hindu Kush Himalayas floods and the key issues
• Good practices in flood risk reduction in the HKH region
• Achievements of HKH HYCOS -supporting
modernization of hydromet networks and
establishment of regional flood information system
• Use of hydromet data
• Cryosphere monitoring in the HKH region
• Lessons learnt
• Opportunities for cooperation
Himalayan glaciers are sources of freshwater reserves which provide headwaters for major river systems in Asia
8 countries of which 6-7
with substantial
cryosphere resources
240 million people in the
HKH
1.9 billion people living
in the mountains and
downstream
Floods in the HKH region
• Extreme flood events in
the HKH region has
increased
• 2013 floods in
Uttarakhand, India killed
more than 5000 people
• 2010 floods in Pakistan
killed 2,000 people and
left 20 million homeless,
with a financial loss of
USD 10 billion (FFC,
2010);
• 2007 floods in India and
Bangladesh killed more
than 3,000 people and left
millions homeless.
South Asia Floods 2017
Key issues in the HKH region
• There is a diversity of technical, scientific, and institutional capacity
• There is limited exchange of real-time data especially across national boundaries – increase lead time
• The integration of risk information into EWS is still weak
• Investment in FEWS is low and of less priority
• Opportunities for sharing knowledge, experiences and know-how
• Establishment of a Regional
Flood Information System in the
HKH-Region - Timely exchange
of flood data and information
through an accessible and user
friendly platform
The Hindu Kush Himalayan Hydrological Cycle Observing System (HKH – HYCOS)
Making information travel faster than flood waters
HYCOS is a vehicle for technology
transfer, training and capacity
building
• Advancement in technology : real-time data through sensors
• Data transmission through CDMA, GPRS/GSM, and satellite iridium
• ICT for risk communication
• Space based technology using earth observations are increasing the lead time, filling data gaps in flood modeling
Innovation in technologies for end to end flood early warning system
Modernization of observation network
• 38 hydrometeorological stations upgraded in four countries(Bangladesh, Bhutan, Nepal, Pakistan)
• Access to > 300 Global Telecommunication Stations of WMO
• Real time data acquisition
The Hindu Kush Himalayan Hydrological Cycle Observing System (HKH – HYCOS)
Regional flood outlook and information system
Enhancing user interface
• Assessment of the
communication of flood early
warning: formal and informal
mechanisms and gaps –
technical, institutional and
sociocultural
• Regional case studies on
best practices in
communicating flood early
warning
• Development of
communication products
• Capacity building and
training
Components of the early warning system (EWS)
CRYOSPHERE in the HKH
Seasonal snowup to 10% of total area
50,000glaciers
Permafrost area exceeding glacier area
Largest reserves of snowand ice outside the polar
region

Glacier monitoring in Nepal
In collaboration with partners in Nepal (DHM, KU) and France
Understand the high mountain processes and address the data gaps

Lessons Learnt
• Technology: flood information system at basin scale
• Limited networks in the region: high altitude – need further strengthening and sharing
• Utility of data and information for developing flood outlook demonstrated the value of real-time data: development of customized products
• Capacity building and training enhanced cooperation and partnerships: support to Glaciology program
• Flood forecasting and warning needs to be integrated with the disaster risk management activities for an effective end to end flood early warning system
• Efforts needed for risk communication, awareness, better preparedness and strengthen institutional mechanisms
Lessons Learnt
• Concerted efforts required for mainstreaming gender into programmes: by end of 2019 9 female glaciologist would have graduated and 5 doing PhD
• Collaboration between projects and various funding agencies multiply the success: in terms of building on, continuity
• Regional cooperation is a long term effort and requires building trust
Opportunities for regional collaboration
• Capacity building• Standardized methods
• Impact based flood forecasting and strengthening capacities
• Early warning and communication products
• Knowledge, Information and data
sharing• Cryosphere services• Transboundary issues
