The Pacific-Australia Climate Change Science and Adaptation Planning (PACCSAP) Water Security in Tuvalu project completed a comprehensive Cost Benefit Analysis (CBA) of potential water security interventions in Funafuti and Vaitupu, two of the major islands in Tuvalu. This poster describes a five-step process to identify water security investments that deliver the greatest benefit at the lowest cost for a water security cost benefit analysis project in Tuvalu.
