Examples of Earth Observation Needs for World Bank Disaster Risk Management Operations David Rogers Senior Hydrometeorological Expert Natural Disaster Mitigation and Earth Observations: a GEOSS Perspective Geneva, 13 January, 2014
Introduction to the World Bank Group • Financial support and technical assistance for developing countries • Bank financing - country implementation - demand driven • Financing for projects, knowledge and data products, global advocacy, technical assistance, advisory services, research, and donor/project coordination • GFDRR is the disaster risk management focal point for the Bank
Partnering with Governments to develop, share and use risk information to build resilience. • Developing innovative tools and adapting methodologies to promote collaboration, analysis and sharing of risk data and information. • Some achievements (always through partnership, on-going): • Rapidly mapped cities • Collaborative Spatial Assessment (CoSA) for post-disaster impact assessments • Geonode: Sharing and Communicating Risk Information • Risk Assessment for Financial and Social Protection • InaSafe: Intuitive tools for local decision makers • Tools to build risk capacity across sectors • World Bank - European Space Agency (ESA) Collaboration in using EO for Disaster Risk Assessment (part of a broader multi-sectoral partnership) • Future goals (again through partnership): • Open Cities: Community Mapping to Capture Exposure • Increasing functionality of risk tools and increased access to global and local datasets • Promotion of Open Data
World Bank EO Needs for DRM (1/3) Exposure Mapping • Baseline exposure (infrastructure, settlements, etc.) • Tracking urbanization patterns • High resolution Digital Elevation Models (DEMs), including monitoring (land subsidence) SRTM (free) LIDAR ($$$) Airborne IFSAR ($)
World Bank EO Needs for DRM (2/3) Hazard Mapping Make EO advances available to developing countries: • Rainfall, drought, flood and landslide monitoring • Historical flood footprints • Land cover determination and monitoring • Slope angle determination • Soil moisture monitoring • Geologic strain rate monitoring • Volcano morphology monitoring In general faster, cheaper and more accurate/reliable risk assessments are needed.
World Bank EO Needs for DRM (3/3) Disaster Response and Recovery Planning • Remote damage assessments • Pre- and post-disaster imagery • Automatic change detection • Crowd-sourced change detection • Visual interpretation for damage level determination • Streamlining of above processes • Reconstruction planning, monitoring and evaluation • Linking with ground (geo-tagging monitoring) • Verification of commitments/reporting by owners, contractors, partners, government, etc.
Why exposure and vulnerability mapping is critical • Tropical Cyclone Fitow – good forecast of the hazard – 18 million people alerted, but…. • Orange alert issued for Shanghai at 5:36 am • Red alert issued at 07:38 am • Problem • warning too late to prevent people from going to work/school/etc. • Result • Gridlock and many people exposed to the hazard; flooded cars, buses, etc. 1,240,000 people directly affected • Public response • why wasn’t the warning issued earlier?
Impact Forecasts versusWeather Forecasts • Timing and details of the hazard • 156 mm of rain starting at 2000 hrs and lasting 12 hours • Yellow alert for tropical cyclone issued at 2100 hrs • Timing and details of the impact • Extensive Flooding • Severe disruption to public services expected from 0600 tomorrow • Recommend schools close and inform families • Recommend all except emergency services to remain off roads
Impact forecasts Impact forecast(t) = Hazard forecast (t) X Vulnerability X Exposure (t) The risk associated with the hydrometeorological hazard depends on knowing how that hazard impacts human beings, their livelihoods, and assets due to their vulnerability and exposure
Case Study from UK Met Office HazardImpact Model: CornwallFlood17thNov2010 Risk =Hazardx(VulnerabilityxExposure) Hazard x Vulnerability x Exposure
Integration ofVulnerabilityandExposure Relative Risk – after integration with vulnerability & exposure [either via Impact Analysis per time step or individual static/semi-static fields]
Risk Matrix used by UK Met Office LIKELIHOOD Risk Matrix – A color is assigned to a warning based on the a combination of potential impact and likelihood
Applied to TC Fitow • Hazard Warning • Yellow alert issued at 21:52 Oct 7th(take preventative measures - emergency services be prepared) • No emergency action is taken • Impact Warning • Red alert issued at 21:52 Oct 7th – due to impact expected during tomorrow’s rush hour • Take emergency action now to prevent high impact
Summary World Bank/GFDRR and partner country priority EO needs for disaster risk management: • High resolution exposure information: infrastructure, settlements and DEMs • Hazard information: hydrometeorological and geological real-time and past event data • Support to recovery: damage assessments and monitoring of reconstruction
