National Workshop on DRR:Innovation and Excellence in Nepal
29 June 2010
Presentation outline:
• Why Community Based Flood Early Warning?• Early days – “Watch and Warn”• Linking downstream with the upstream• Scaling up and extension• Way forward
Why - Community Based Flood Early Warning System
• Flood Warning is a concern and interest of communities living along the flood prone zones
• Locally Flood Warning starts from members of communities and dissemination takes place into the community
• Flood Warning is required as it originates in one location and affects in another location
• The existing traditional warning gives limited response time
Early Days – Flood Warning“Watch and Warn”
Pilot initiative in Bhandara, Chitwan- 2002
- Visual observation at local level – “Watch and Warn”
- Dissemination of the information through “Electric Siren”
Additional supports provided
- Protection of river banks
- Awareness and trainings
- Management of the Warning Tower
Limitations of Early Watch and Warn System
- Electricity interruptions
- Limited coverage of the siren
- Limited coverage of the visual sight
- Limited response time
- Less community interest
Additional needs realised
• Increase in visual range
• Rescues bridges and passages
• Rescue equipment
• Emergency shelters
• Electricity back up
• Back up to electric siren
Improvement in “Watch and Warn” System
Chitwan and Nawalpasai- 2005
• Genuinely based on intra-community warning system
• Extensive awareness programmes
• Provision of life saving equipment and other materials like boat, life jacket
• Construction of small scale mitigation structures like bridges, bio-dykes, shelters etc
• Pre-identification of evacuation route
Improvements in “Watch and Warn”
Higher tower with additional facility
Hand siren Rescue boat
Emergency Shelter
Rescue bridge
Beyond “Watch and Warn”
Linking Downstream Communities to Upstream River Information
Upstream river gauge Downstream
communities
“Linking downstream with upstream"
With equal emphasis on all the four elements of EWS
Upstream to Downstream Communication
Communicating river information to downstream through radio
Monitoring river level
Communicating the information through hand mic
Communicating the information through siren
Early Warning Communication System
Beyond “Watch and Warn”
Scaling up and Extension
Telephone +
Telemetry (internet)
Telephone cum Telemetry EWS
Scaling up and extension…
Way forward
• Make EWS a priority in National DRR
• Develop National EWS Strategy (in progress)
Way forward
• Build capacity of the communities and stakeholders in EWS
• Build necessary infrastructure for National EWS
