Modelling Sea Level Rise
Nathan will discuss NGIS Australia’s work with the CRCSI and the Australian Government to deliver capacity building to a number of Pacific Countries around climate change adaptation. As part of the Pacific-Australia Climate Change Science and Adaptation Planning (PACCSAP) program high resolution LiDAR data has been provided to Tonga, Samoa, Papua New Guinea and Vanuatu. This data has provided the countries with the resolution required to be able to perform accurate sea level rise modelling around key coastal areas. The subsequent inundation layers are being used to analyse current and future risk relating to sea level rise as well as providing input into climate change planning at a ministerial level. The PACCSAP Program aims to strengthen partner country capacity to assess vulnerability to climate change and develop robust adaptation strategies.
Rising sea-levels over the next several decades and resulting wave impact, particularly at high tide, will rapidly deteriorate the existing coastline and inundate infrastructure along many key populated areas of pacific island countries.
