Using Geo-information analysis to improve Pacific Disaster Resilience

Professor Michael Petterson,

Director, Geoscience Division

Geosmart Asia 17-19 October Kuala Lumpur

Pacific Environment: volcanoes, cyclones, storm surge, Floods, landslides, tsunamis, unsafe ground conditions, earthquakes…etc.

Rabaul, PNG

Samoa tsunami, 29 Sep 2009, Mag 8.1: 189 killed 30% of GDP Affected

Cyclone PAM: 13 March 2015: Vanuatu: 66% of GDP Affected

Low lying Atoll Countries: King Tides Storm Surge Droughts

Best way forward: Science into risk, policy and advice…but how?

Complex seismograph BUT: understanding Science & data is difficult

So we need an expert team and systems

And we pull together an informed decision support tool

Triggers & causative factors for landslides in Papua New Guinea (Joanne Robbins)

Landslide-triggering event inventory: PNG

Triggering event meta-data sources

(1) Technical/Site inspection reports (PNG MRA*2 & DMPGM*3) (2) Journal publications (3) Newspaper records (4) Internet publications (ReliefWeb) (5) Supplementary archives (Dartmouth Flood Observatory, USGS Earthquake Catalogue)

Landslide Types*1

*1 Landslide type images courtesy of USGS from their website: http://pubs.usgs.gov/fs/2004/3072/images/Fig3grouping-2LG.jpg *2 MRA = Mineral Resources Authority in PNG *3 DMPGM = Department of Mineral Policy and Geohazards Management

Landslide-triggering event is a meteorological, geological

• r hydrological event/hazard which led to landslides.

Regional: PacGeo

Deployed in 2013 Cloud deployed 900~ layers 950~ related documents 40~ Users across PICs trained www.pacgeo.org Small offline functionality In countries with limited Internet access Use Geonode & GeoServer software

Regional: Pacific Risk Information

Capacity Building in PIC

77%

GIS/RS Users in Pacific Governments, Regional Agencies and Academia, use QGIS according to a recent online survey conducted by GIZ/MacBIO.

90+

Pacific Island Nationals trained on QGIS and related FOSS4G Toolsets in 2015 alone, by Geoscience Division, Pacific Community, via Regional Workshops, In-Country Training, and Internship attachment Schemes.

4+

Major Regional Players actively involved in QGIS Capacity Building in the Pacific Island Countries:

• SPC (Geoscience, Fisheries and Stats Division)
• CSIRO (Kiribati, Solomons)
• GIZ-funded MacBIO/IUCN
• USP (Bachelor of Geospatial Science, 2015 -)

Resilient Investments: Conclusions

• First: know you hazard and know your risk
• Second: Map the hazard, map the risk
• Third: Combine with socio-economic &

infrastructure data

• Fourth: Calculate Probabilities
• For everything: work closely with your target

audience all the way (planners, government, investors): design tools they know and will use to inform decisions
