The Pacific Climate Change Science Program is part of the Australian’s International Clilmate Change Adaptation Initiative which was launched in 2008 to meet high priority adaptation needs of vulnerable countries in the Asia-Pacific region, particularly Pacific island nations and East Timor. There are 15 partner countries involved in the Pacific Climate Change Science Program. The PCCSP is supported by the Australian Agency for International Development (AusAID) in collaboration with the Australian Department of Climate Change and Energy Efficiency (DCCEE). It is delivered by the Bureau of Meteorology and the Commonwealth Scientific and Industrial Research Organisation (CRISRO), through their research partnership in the Centre for Australian Weather and Climate Research (CAWCR). The program also works in close cooperation with regional Pacific organisations and other research institutions including Secretariat of the Pacifc Regional Environment Programme (SPREP), Secretariat of the Pacific Community (SPC), Pacific Islands Applied Geoscience Commission (SOPAC), United Nations Development Programme (UNDP) and the University of the South Pacific (USP). The PCCSP overall aim is to help the partner countries better their understand of past, current and future climate and build capacity in climate science within these countries. The PCCSP is assisting the region address two key principles of the Pacific Islands Framework for Action on Climate Change 2006-2015; firstly, improving the understanding of climate change and secondly, the provision of education, training and awareness. These also relate to JNAP Goal 2 (Enhanced Technical Knowledge base, information, education and understanding of climate change adaptation and effective disaster risk management & Goal 3 (Analysis and assessments of vulnerability to climate change impacts and disaster risks. A climate change database management system was established at the Tonga Meteorological Service as part of this program.
