As part of the Australian Government's International Climate Change Adaptation Initiative (ICCAI), the Pacific Adaptation Strategies Assistance Program (PASAP) and its successor, the Pacific-Australia Climate Change Science and Adaptation Planning (PACCSAP) program, aim to strengthen partner country capacity to assess vulnerability to climate change and develop robust adaptation strategies. Discussions during 2010 between the Australian Government Department of Cliamte Change and Energy Efficiency (DCCEE) and Tonga's Ministry of Environment and Climate Change (MECC) highlighted the potential for supporting Action 2.1 of Tonga's Joint National Action Plan on Climate Change Adaptation and Disaster Risk Management 2012-2015 (JNAP). Action 2.1 specifies the need for high resolution imagery was also captured with the LiDAR. The surveys were completed in Octorber 2011 and the data was processed to produce high resolution digital elevation models (DEMS) and other derived products. Phase one also assessed institutional technical capability whithin the Government of Tonga to receive and use the elevation data, and scoped capacity building requirements to sustainably use the data for coastal inundation modelling and risk assessment.
Objectives: Captured high resolution topographic and bathymetric data of Tongatapu and Lifuka through airborne LiDAR surveys
The Kingdom of Tonga is a large tropical archipelago of 169 is- lands spread over 700,000 square kilometres of the western South Pacific Ocean. Tonga lies just west of the International Date Line, directly south of Samoa and north of New Zealand. Most of the population lives in low-lying areas. In Western Tongatapu, parts of the communities lay less than two metres above sea level rendering properties vulnerable to flooding and coastal erosion caused by sea level rise, storm surge, heavy rain and catastrophic events such as tsunamis and cyclones. House-holds in this district tend to be of low economic means and tend to have limited ability to adapt or relocate The EU-GIZ ACSE programme helps people in 15 Pacific Island countries address two common challenges: adapting to climate change and reducing their dependence on fossil fuels. GIZ is supporting the Government of Tonga and its dedicated project team to implement coastal protection trials in selected areas of Western Tongatapu. The team is working in close part- nership with the people of the Hihifo District.
Objectives: The project aims to increase resilience of six coastal communities in Western Tongatapu to climate change impacts and to sustain their livelihoods
