Understanding the Spatial and Temporal Occurrence of Landslides Using Satellite and Airborne Technologies: Papua New Guinea

E-mail Print PDF

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.

E-mail Print PDF

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.’

Building Capacity for Resilient Development

E-mail Print PDF

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.

Newsflash

05 September 2013, Majuro, Republic of the Marshall Islands - At the occasion of the Pacific Islands Forum (PIF), European Union Commissioner for Climate Action Mrs Connie Hedegaard and the Secretariat of the Pacific Community’s Director General Dr. Jimmie Rodgers and the Secretary General of the Secretariat of the African, Caribbean and Pacific (ACP) Group of States, Mr Alhaji Muhammad Mumuni, have signed the "ACP-EU Building Safety and Resilience in the Pacific" programme.

The European Union (EU) will provide 20 million Euro to support the Pacific states in addressing the impacts of climate change and the urgent need to improve resilience to natural disasters.

The high vulnerability of Pacific Island Countries to disaster is well known. This is further exacerbated by their often small land areas as well as their narrow, subsistence based fragile economies. Natural hazards undermine development and the achievements of the Millennium Development Goals (MDGs).

This Programme responds to these challenges and will strengthen the capacity of the Pacific states to address existing and emerging challenges with regard to the risks posed by natural hazards and related disasters, while maximising synergies between disaster risk reduction (DRR) and climate change adaptation (CCA).

"For the Pacific people, climate change is not about a distant future. It has become the new normal. This programme will help the Pacific states in their efforts to adapt to this new climate reality. The Pacific states can count on Europe to continue its climate cooperation in the region”, said European Climate Action Commissioner Connie Hedegaard.
