Sea-level rise impact on coastal areas of Estonia

Due to long coastline (3,794 km in total) and extensive low-lying coastal areas, global climate change through sea-level rise will strongly affect the territory of Estonia. A number of valuable natural ecosystems (both, marine and terrestrial) containing rare plant communities often rich in species, but also suitable breeding places for birds will be in danger. Most sandy beaches high in recreative value will disappear. However, isostatic land uplift and location of coastal settlements at a distance from the present coastline reduce the rate of risk. Four case study areas characterizing all the shore types of Estonia have been selected for sea-level rise vulnerability and adaptation assessment. Preliminary results and estimates of vulnerability to 1.0 m sea-level rise by 2075 for two case study areas - Hiiumaa, West-Estonian Archipelago and Parnu-Ikla, south-western coast of the mainland are presented in this paper.
