Small Island Developing States (SIDS) share a number of socio-economic and environmental vulnerabilities that challenge their growth and development aspirations. Their climate, geographical, and topographical features as well as their critical reliance on coastal transport infrastructure, in particular seaports and airports exacerbate these vulnerabilities, including their susceptibility to climate change factors, such as sea-level rise and extreme weather events. At the same time, however, SIDS capacity to adapt and build the resilience of their coastal transport infrastructure is constrained. SIDS have limited capacity to conduct targeted vulnerability studies, carry out cost assessments, and identify and prioritize requisite adaptation options. Two issues are pervasive: (a) the lack of information and data at a downscaled local level leading to partial understanding of the magnitude of the problem; (b) the insufficient cooperation and coordination of action at all levels. This project aims to address these challenges by strengthening the capacity of policy makers, transport planners and transport infrastructure managers in SIDS to (a) understand climate change impacts on coastal transport infrastructure � in particular seaports and airports - and (b) take appropriate adaptation response measures.
