Small Island Developing States are considered as one of most severely affected by climate changeand sea-level rise. Some atoll nations would virtually disappear with a sea-level rise of one metre.The objective is to derive a first-cut classification of coastal protection technology for the SmallIsland Developing States to address sea-level rise. First, an assessment is made of the existing andfuture adaptation measures to sea-level rise in the latest 35 English-language NationalCommunications submitted by the Small Island Developing States to the UNFCCC. Next, a widevariety of adaptation measures is culled from key coastal engineering manuals and other sourceswith a focus on more innovative tools and ideas beyond the traditional hard and soft measures. Thisyielded several possible adaptation tools that could be used by the Small Island Developing States,and with further research, more tools could be applied. In conclusion, a first-cut classification ofcoastal protection technology is proposed for the Small Island Developing States to address sea-level rise. The resulting table shows eight categories graded from the usual hard and soft measures to new and innovative ideas.
