European Commission
• Europe and European Commission are large players in international disaster management
• Policy and action for disasters– Humanitarian aid office (ECHO):
� largest humanitarian aid donor in the world
– Civil Protection Mechanism� Coordination of European first response
� Monitoring and Information Center (MIC), field coordination missions
• JRC provides scientific and technical support
– External Relations: � Prevention, mitigation, reconstruction programmes
� World Bank Post Disaster Needs Assessment: JRC does technical implementation
– Development:� Reduction of vulnerability and improvement of resilience
� African Caribbean Pacific Observatory: direct, long-term support to ACP countries

Disaster monitoring for earlier response
• JRC Unit for Global Security
and Crisis Management– Preparedness
– Response
– Recovery
– Prevention
– Risk reduction
• Alert and response systems for
natural disasters– Real time systems: GDACS
– Physical and risk modelling
– Strong practitioners community
– Multidisciplinary scientific
community

9GMES Workshop, Bulgaria
Disaster alert: systematic impact analysis
• Risk analysis– Risk = Hazard x Population x Vulnerability
� Hazard = 0 then Risk = 0
� Population = 0 then Risk = 0
� Vulnerability = 0 then Risk = 0
• Impact analysis is similar– Impact = Event magnitude x Population in affected area x Vulnerability

multiple observations per day
– Surface water changes
– Pixels of 10x10km2
– Very sensitive
• www.gdacs.org/flooddetection
GMES Workshop, Bulgaria
• Virtual hydrographs
• Daily flood maps

Floods: remote sensing
• Validation: Pilot in Namibia– Up to 20 day early warning
GMES Workshop, Bulgaria
• Can be used as trigger for high
resolution satellite acquisitions
20 days
