Key Idea Why small islands are vulnerable to climate change:
Small islands are often economically. socially and physically vulnerable by their very nature. Because they are unable to produce all the goods and services to meet domestic needs, they are often import-dependent. Many rely on tourism to generate foreign exchange to balance this demand for imported goods and services. Due to their small land masses, small islands are typically land-resource constrained. This means that there are limited places for people to live, space for infrastructure, areas for waste disposal, agricultural production, industrial development, etc.
Many small islands are already at risk from many environmental hazards, such as coastal, river and rain-induced flooding, tropical cyclones and storm surges. The battering received from many of these hazards can make islands particularly vulnerable to other changes. Small islands, which are already vulnerable economically and physically, will be placed under increasing pressure by some of the impacts of climate change.
