Spatial ICTs for risk identification and risk reduction:
Three geographic scales and three challenges

ICTs are widely used, but challenges remain
• Successful shift from disaster response to risk reduction
• Bank support for risk analysis and risk management at all spatial scales
• Spatial ICTs play a central role
• GIS, GPS, remote sensing – linked by internet and other communication technologies
• But: Technology is not the main problem. The bottlenecks are institutional!
Bank initiatives at three geographic scales
• Global natural disaster risk
• Country catastrophic risk assessment
• Local risk identification
• Awareness raising, priority setting, screening tool
• Improving baseline information, methodologies, tools
• Support specific interventions: mitigation & transfer
The standard risk assessment modelapplies across spatial scales
Hazard probability
Exposure Vulnerability
Damages
Losses
Mitigation orrisk transfer

geophysicaldrivers
policy analysis, costs/benefits

Country catastrophic risk assessment
• Operational risk assessments
– E.g., Central America Probabilistic Risk Assessment
– National level assessments in hotspot countries
• Knowledge management: tools and guidance
– MIRISK open source tool for risk assessment and guidelines on what to do about it
– “Guidance Note for Common Country Catastrophic Risk Assessment Methodology (C3RAM)”, GFDRR
– Post disaster information sharing: “Using Data for Disaster Response” (PREM/GFDRR)
Local risk identification:Use of very high resolution satellite data
• Image derived physical risk factors and exposure data
• Complements GPS field data collection
• Supports local risk identification
• Case studies: Legaspi (Phl) and Sana'a (Yem)
Challenges
• Capacity
– Insufficient at local levels
– Leading to highly centralized disaster management
• Coordination
– Inter-agency coordination within countries
– Internationally (UN/national/NGOs) during disaster response
• Content
– Data and tools: limited access and black box models
– Data readiness
What to do
• Capacity
– Learn from decentralization of other government functions
– Invest in learning at the local level
• Coordination
– Use mix of incentives and enforcement while minimizing coordination costs (e.g., spatial data infrastructure)
– High level agreements on binding protocols for IT use during disaster response
• Content
– Invest in data and analytical tools as public goods
– Ensure data readiness well before disaster strikes
