Understanding the Spatial and Temporal Occurrence of Landslides Using Satellite and Airborne Technologies: Papua New Guinea
Last Updated on Friday, 01 August 2014 14:32
Data Release Report by Joanne Robbins
Landslides pose a significant threat to life and infrastructure in Papua New Guinea (PNG), with numerous movements being recorded annually. Such events are typically instigated by the combined effects of different geomorphological control factors, such as slope or geology, and the influence of a triggering event (i.e. an earthquake or heavy rainfall). Rugged topography and high seismicity combine in PNG, to make the region highly susceptible to large-volume, earthquake-induced landslides, while the climate encourages widespread rainfall-induced landslides. Of the two triggering mechanisms, understanding rainfall-induced landslide occurrence offers the best scope for early warning/forecasting system development, as meteorological models and data availability improve.
This paper presents an overview of research conducted to understand regionally-based, rainfall-induced landslide occurrence in PNG. Given the regional focus of this research and the need to develop a cost effective and reproducible methodology, pre-existing or freely available satellite and airborne data have been used. The aim of this research was to develop models capable of identifying rainfall events with the potential to trigger landslides, as well as models that distinguish areas of heightened landslide susceptibility from those with low/no landslide susceptibility. Together, these modelling approaches can be used to generate a broad-scale early warning/forecasting system, which could help to reduce the losses associated with landslides across PNG.
Building Capacity for Resilient Development
Last Updated on Wednesday, 16 July 2014 09:05
Pacific Island countries are amongst the most disaster prone in the region, exposed to natural hazards such as floods, droughts, tropical cyclones, earthquakes, volcanic eruptions and tsunamis, which all pose a significant challenge to development in the Pacific region. A single disaster event can result in losses in the millions of dollars and can undo progress in areas such as infrastructure, agriculture, healthcare and education.
Despite recognition of the importance of disaster resilient approaches to development, many countries face challenges in identifying ways to effectively mainstream risk reduction considerations into national development planning processes. To address this, the Secretariat of the Pacific Community, in partnership with the Asian Disaster Preparedness Centre is holding a one week training workshop which focusses on how to mainstream Disaster Risk Reduction into development.
The training, in Nadi from 14-18th July, includes participants from the Cook Islands, Fiji, Samoa, Solomon Islands, Tonga and Vanuatu with representatives of National Disaster Management Offices and ministries responsible for national planning and finance. Representatives from the Pacific islands Forum Secretariat, Secretariat of the Pacific Community, Secretariat of the Pacific Regional Environment Programme and United Nations Development Programme will also participate in the training workshop.

CROP Agencies and International Stakeholders Highlight the Significance of Spatial Data for the Pacific
Last Updated on Friday, 11 July 2014 14:34
Tuesday, 24 June 2014, Secretariat of the Pacific Community (SPC), Suva - A broad range of geospatial data experts, managers and stakeholders from the Council of Regional Organisations in the Pacific (CROP), as well as partner agencies convened for the 2nd CROP Spatial Data Infrastructure meeting. The session was held at the Secretariat of the Pacific Community (SPC) in Suva on June 17th to 18th 2014.
The meeting was opened by Prof Michael Petterson, Director of SPC’s Applied GeoScience and Technology Division (AGTD), where he highlighted the various challenges facing effective geospatial data management in the Pacific. Such challenges cited were under-skilled staff, limited understanding by responsible personnel of available datasets, and obsolete formats of residing data. He encouraged the meeting to bring about some positive outcomes to address these and the many other challenges.

SPC receives two awards for satellite imaging
Last Updated on Monday, 14 July 2014 15:19
Friday 11 July 2014, Secretariat of the Pacific Community (SPC) headquarters, Noumea, New Caledonia – The Secretariat of the Pacific Community (SPC) geographic information systems (GIS) and remote sensing team has received two awards from the world’s leading supplier of satellite imagery, DigitalGlobe Inc., based in Colorado, USA.
They received a Partner Excellence Award 2014 for increased sales volume and meeting business growth expectations. SPC is the only authorised reseller of DigitalGlobe products in the Pacific Island region.
SPC members currently receive the highest-resolution satellite image data commercially available at some of the lowest prices on the planet.
Speaking at the awards ceremony held at SPC’s Suva Regional Office on Thursday 10 July, 2014 Wolf Forstreuter, GIS and Remote Sensing Specialist, explained emerging fields in the application of satellite imagery data.
‘Emily Artack, our Maritime Boundaries Technical Officer, used satellite image data for determination of maritime boundaries between Kiribati and Marshall Islands. This is a new application for satellite image data. And it is the first time that the International Seabed Authority has recognised satellite imagery as a legal tool to determine boundaries.’
What is the Pacific Platform for Disaster Risk Management?
Last Updated on Wednesday, 25 June 2014 15:44
The 6th Session of the Pacific Platform for Disaster Risk Management, was recently co-convened by the Secretariat of Pacific Community (SPC) and the United Nations Office for Disaster Risk Reduction (UNISDR) from 2nd - 4th June at the Novotel Hotel in Suva, Fiji.
This important meeting was seeking to gain support for the draft Strategy for Climate and Disaster Resilient Development in the Pacific (SRDP) and the development of the Post- 2015 Framework on Disaster Risk Reduction which is to be endorsed at the 3rd World Conference on Disaster Reduction (3WCDRR) in Sendai, Japan in March 2015. Watch here for a 2-minute summary of key stakeholder views on the success of the Platform.
