  Bangladesh is recognised to be one of the countries most vulnerable to climate change. Over the course of a century, 508 cyclones have affected the Bay of Bengal region, 17 percent of which are believed to have made landfall in Bangladesh. Natural hazards that come from increased rainfall, rising sea levels, and tropical cyclones are expected to increase as the climate changes, each seriously affecting agriculture, water and food security, human health, and shelter. It is estimated that by 2050, a three-foot rise in sea levels will inundate some 20 percent of the land and displace more than 30 million people. To address the sea level rise threat in Bangladesh, the Bangladesh Delta Plan 2100 has been launched.
