Abstract
- Pacific Islanders have been exposed to risks associated with climate change. Samoa as one of the Pacific Islands are prone to climatic hazards that will likely increase in coming decades, affecting coastal communities and infrastructure around the is- lands. Climate models do not predict a reduction of such disaster events in the future in Samoa; indeed, most predict an increase in such events. This paper identifies key infrastructure and their functions and status in order to provide an overall picture of relative vulnerability to climate-related stresses of such infrastructure on the island. By reviewing existing reports as well as holding a series of consultation meetings, a list of critical infrastructures were developed and shared with stakeholders for their consideration. An indicator-based vulnerability model (SIVM) was developed in collaboration with stakeholders to assess the vulnerability of selected infrastructure systems on the Samoan Islands. Damage costs were extracted from the Evan cyclone recovery needs document. On the other hand, criticality and capacity to repair data were collected from stakeholders. Having stakeholder perspectives on these two issues was important because (a) criticality of a given infrastructure could be viewed differently among different stakeholders, and (b) stakeholders were the best available source (in this study) to estimate the capacity to repair non-physical damage to such infrastructure. Analysis of the results suggested rankings from most vulnerable to least vulnerable sectors are the transportation sector, the power sector, the water supply sector and the sewerage system.
