Abstract

Islands in the Pacific region rely heavily on their fresh groundwater, and for a number of islands it is the only reliable source of freshwater throughout the year. Stresses on groundwater resources in many Pacific Island countries are set to escalate in the future with projected population and economic growth. In addition, there are likely to be future climate impacts on groundwater availability and quality. Although a number of studies have been undertaken at a local scale, very limited information is available to consider the impacts of future climates on groundwater systems at a regional scale. This project provides a first-pass regional-scale assessment of the relative potential vulnerability of groundwater to: (i) low rainfall periods and (ii) mean sea-level rise for 15 Pacific Island countries and territories. The dataset associated with this report can be obtained from www.ga.gov.au using title "Pacific Island Groundwater Vulnerability to Future Climates Dataset" or catalogue number 81575.

Lineage

Geoscience Australia has undertaken a desktop study entitled 'Pacific Island groundwater and future climates: first-pass regional vulnerability assessment' for 15 Pacific Island countries and territories. This study has been conducted in consultation with Pacific Island groundwater hydrology experts. Where possible, this project has drawn on in-country expertise and consultation with the Applied Geoscience and Technology Division (SOPAC) of the Secretariat of the Pacific Community . This project was funded by the Pacific-Australia Climate Change Science and Adaptation Planning (PACCSAP) Program and administered by the Australian Government Department of the Environment.
