With a population of 130 million, Bangladesh is already facing the impacts of climate change. No other country knows about the impacts of climate change better than Bangladesh, where millions of people are already suffering. The lives and livelihoods of coastal people are more vulnerable than in inland areas of Bangladesh because they are continuously facing natural calamities, especially cyclones, storm surges and floods, and becoming victims of them. To reduce the impact of climate change, mangrove forests are playing an important role, and are also vital for the country’s socio economic development. A large portion of the population of Bangladesh lives in coastal areas and depends on local natural resources for their livelihoods.Mangroves play an important role in maintaining the coastal ecosystem and provide a variety of environmental supports. They serve as protection for a myriad of juvenile aquatic species, function as a habitat for a variety of terrestrial fauna and are a source of nutrients that help to sustain many complex food chains. In the mangrove ecosystem area of Bangladesh, the economic, social and cultural life is closely related with mangrove flora and fauna, its lunar, tidal and seasonal cycles and the associated fish, shrimps and crabs found there.
