the region recommend further focus on mangrove restoration and management and advocating for adaptation of human populations, through processes like managed retreat and investments in resilient infrastructure. Etymology The literal meaning of Sundarbans () is "beautiful forest". Alternatively, it was proposed that the name is a corruption of Samudraban, Shomudrobôn ("Sea Forest"), or Chandra-bandhe, the name of a tribe. However, the likely origin of the word is Sundari or Sundri, the local name of the mangrove species Heritiera fomes abundant in the area. History The history of human settlement in the Sundarbans area can be traced back to Mauryan era (4th-2nd century BCE). A ruin of an abandoned city was found in the Baghmara Forest Block that is attributed to Chand Sadagar, a pre-Mauryan semi-historical figure in Bengali folklore. Archaeological excavation at Kapilmuni, Paikgacha Upazilla, north of the Sundarbans in Bangladesh, revealed ruins of urban settlement dating back to the early middle ages. During the Mughal period, forest tracts were leased out by the local rulers for establishing settlements. In 1757, The British East India Company obtained proprietary rights over Sundarbans from the Mughal Emperor Alamgir II and completed mapping the area in 1764. However, systematic forest management started a century later. The first Forest Management Division to have jurisdiction over the Sundarbans was established in 1869. In 1875 a large portion of the mangrove forests was declared as reserved forests under the Indian Forest Act of 1865 (Act VIII of 1865). The remaining portions of the forests were declared a reserve forest the following year and the forest, which was so far administered by the civil administration district, was placed under the control of the Forest Department. A Forest Division, which is the basic forest management and administration unit, was created in 1879 with the headquarters in Khulna, Bangladesh. The first management plan was written for the period 1893–1898. Geography The Sundarban forest lies in the vast delta on the Bay of Bengal formed by the super confluence of the Hooghly, Padma (both are distributaries of Ganges), Brahmaputra and Meghna rivers across southern Bangladesh. The seasonally flooded Sundarbans freshwater swamp forests lie inland from the mangrove forests on the coastal fringe. The forest covers of which about are in Bangladesh. The Indian part of Sundarbans is estimated to be about , of which about is occupied by water bodies in the forms of river, canals and creeks of width
