Best way forward: Science into risk, policy and advice…but how?
Complex seismograph
BUT: understanding Science & data is difficult

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

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 -)
• www.pacgeo.org/edu

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
