Abstract—Majuli, one of the largest inhabited river islands in the world, is under serious threat due to large-scale bank erosion by the Brahmaputra River. There is urgent need to preserve this socio-culturally rich island of over 0.2 million people. Erosions have been shrinking its landmass signifi-cantly and thereby causing enormous pressure on its eco-system. Through this study, an attempt has been made to assess the effect of flood and erosion on the island, its na-ture, habitats and eco-system. Survey maps and satellite data are considered as major inputs to this study. Inputs from various sources in the island including associated gov-ernment agencies are utilized in this study. Analyzed data indicate that the island eroded at an annual rate of 0.71 sq-km from 1914 to 1949 and alarmingly at an average rate of 3.43 sq-km in subsequent years. Recurring major floods have blanketed fertile land with unproductive silt and shrunk areas of water-bodies. Remedial measures to coun-ter all these diminishing phenomenon and conservation of its natural resources including restoration of water-bodies are discussed. For conservation and restoration of the de-graded island, people’s participation is considered very essential.
