These nations are far from homogeneous but they do share numerous features, including narrow resource bases, dominance of economic sectors that are reliant on the natural environment, limited industrial activity, physical remoteness, and limited economies of scale.
Due to close connections between human communities and coastal environments, SIDS are particularly exposed to hazards associated with the ocean and
