Background: The ADB Project

• Main ADB contact: Mayumi Ozaki, South Asia Department

• ADB team members: B.R. Fontejon, Operations Assistant, SARD

H. Mukhopadhyay, Public Management Economist, SARD

I. O’Donnell, Disaster Risk Management Specialist, RSDD

• Project users/promoters:

- Ministry of Food and Disaster Management (MFDA)

- Center for Environmental and Geographic Information Services (CEGIS)

- WorldBank, others tbc?

• Project context:– ADB 42249-013: Capacity Building for Disaster Risk Finance (March 2013 - March 2015)

– Need for design and implementation new financial instruments for disaster risk management (floods, cyclone, other)

• Information requirements:– EO to support assessment of nature of disaster and catastrophe risk profiling: probability of occurrence, and

the potential loss of, or impact on, life and physical capital.

– EO independent mapping and monitoring of land use / land cover status and historical floods

Service 1: Land use / land cover mapping and DEM

Service 2: Historical flood mapping

The EO Products: What They Are

Flood maps and trends in relation to rainfall history

8

Service 3: Disaster risk data or maps

The EO Products: What They Are

This service delivers disaster risk data and maps for floods, cyclones visualised through the Lizard platform.

Flood damage can be calculated with an existing flood damage calculator developed in cooperation with Dutch water boards and knowledge institutes.

This calculation is based on land-use, flood depths and duration (see figure). Specific indicators for Bangladesh tbc.

Where available: integrate open source data on geohazards such as earthquake and fault lines

The EO Products: What They Bring

• Benefits of EO:

– Higher accuracy DEM and land use/cover improves assessment of physical capital and damage

Overall service enables more efficient risk profiling and insurance solution:

– Better risk assessment - More accurate estimation of loss potential and potential threats (floods, cyclone), especially by deriving more complete historical trends to assess risk;

– More efficient response to claims - Better insight, cheaper and faster than field visits, better large area overview, more objective and independent, improved access to more useful satellite information, less fraud prone, leading to faster and more complete claims settlement;

• Limitations / Constraints– Frequent cloud cover especially during monsoon season necessitates use of radar;

– Fragmented historical and geographic coverage necessitates multi-sensor approach;

– Auxiliary data needed: navigation, city maps, physical capital and damage indicator data)

• The expected impact of this service on the specific ADB project:

more efficient financial protection in disaster risk management by better risk profiling and insurance solutions

The EO Products:Previous Case Studies

• Examples of previous projects:

• Bangladesh implementation of Lizard GIS/MIS system to support monitoring and decisions making in the €31.5 million Blue Gold programme (2013-2019);

• Bangladesh satellite for crops project (2013-2015) with CEGIS and BRAC to deliver crop, flood and drought monitoring information to support farmers and new crop and disaster risk insurance initiatives;

• Colombian government support for Colombian National Climate Adaptation Strategy (2013-2014) with Deltares, Unesco IHE and others, delivering historical flood mapping;

• Bangladesh ESA DUP Marketbasar project (2000-2001) satellite information products for the agriculture and flood with CEGIS. Radarsat SAR-based flood extent, depth and duration and crop damage maps;

• Bangladesh ESA DUP FLOMON project (1998-1999) on flood monitoring demonstration and operation, CEGIS and SPARSSO using ERS SAR;

• Indonesian government support for national agriculture and crop insurance system development (2014-2016)

• Support Netherlands government Flood damage calculator (2012-2013) with Dutch water boards and knowledge institutes, for Disaster Risk Finance assessments.

• Dutch Maps for EU Flood Risks Directive (2013) automatic service for processig flood risks maps (frequencies, maximum waterlevels, arrival times).
