Pacific Island Groundwater and Future Climates: First-pass Regional Vulnerability Assessment Map 1: Potential vulnerability of groundwater in the Pacific region to future rainfall (2035-2064)

This map shows the relative potential vulnerability of groundwater systems on islands in the Pacific region to projected lowest mean annual rainfall during ENSO phases for the period 2035-2064, considering rainfall date under both moderate and higher emissions scenarios (RCP4.5 and |RCP 8.5). Potential vulnerability was assessed for the assumed principal aquifier on islands with potential for supporting permanent fresh groundwater. 

This map is Map 1 of a series of 7 maps that were developed as part of the Pacific Island Groundwater and Future Climates: First-pass Regional Vulnerability Assessment maps were developed by Geoscience Australia for the Pacific-Australia Climate Change Science and Adaptation Planning (PACCSAP) programme.
