Baseline data on erosion and accretion in the Laccadive, Amindivi and Minicoy group of islands which were generated during the period 1993–2005, are documented in this chapter. The beach morphological data shows that coastal erosion is a serious problem faced by the islands. Often these changes badly affect the livelihood of the local population, especially during the monsoon season. Erosion in the island is part of a cyclic process during which the beach material is carried away by wave action, tidal currents, littoral currents and other coastal processes. The most serious incidents of coastal erosion in the island were reported during a cyclone/storm event. The studies on coastal erosion would help to make strategies for disaster mitigation measures in the islands.
