Overview
The islet is one of a number of "vanishing islands" in India's part of the delta: in the past two decades, four islands – Bedford (or
There are multiple causes[6] of the disappearances of islands in the delta, including sea level rise, coastal erosion, cyclones (while the number of cyclones has decreased, their intensity has increased),[7] mangrove destruction and coastal flooding.
In 1974 the Farakka Barrage began diverting water into the Hoogly River during its dry season. During each monsoon season almost all the Bengali delta is submerged, much of it for half a year.[8] The sediment of the lower delta plain is primarily advected inland by monsoonal coastal setup and cyclonic events.[9] One of the greatest challenges people living on the Ganges Delta may face in coming years is the threat of rising sea waters caused by subsidence (sinking) in the region. Residents have to be careful building on the river delta, as severe flooding sometimes occurs.
A 1990 study noted "There is no evidence that
Overall population of the Sundarbans has risen 200% to nearly 4.3 million.[12]
