Climate change and forest degradation are the common phenomena for the real cause of the natural disaster. Forest plays an important role to conserve the coastal ecosystem in Bangladesh. It reduces disaster and other calamites. We are facing different natural disaster and calamities due to degraded the forest and illicit cuttings of the trees. Climatic hazards, including extremes like floods, cyclones, tornado, tsunami, Ayla, Lyla, storm surge, water logging, tidal bore, etc are not new to Bangladesh and the country has a scarred history claiming many lives and resulting in losses of assets in the Sundarbans and the coastal region of Bangladesh. Forest and forestry sectors are only the natural peace conserving source of the earth. Revival of forest and forestry can also reduce the disaster. The most likely cause of warmer atmosphere is increased concentrations of green house gases in the atmosphere. Climate change in general and its consequences are among the pressing issues in future. About 20-30 million people live in the coastal areas within i meter elevation from the high tide level and these people are in the frontline of the consequences. The consequences of rising sea levels and extreme temperatures are becoming increasingly real and immediate in their everyday lives. Food, health, fiber, biodiversity, water resources, coastal ecosystems and settlements have been ranked to highly vulnerable while human health as moderately vulnerable to climate change. The developing countries are causing global warming condition. A total of 3, 63,346 dwelling were completely destroyed while 8, 15,628 partially damaged. Crop lands of 4, 61,399 acres were complete damaged and 12, 25,304 acres of standing crops partially damaged during 15 November, 2007 by the Sidr. Human and livestock casualties were 3347and 4, 61,750 respectively. About 830,000 million hectares of arable land is affected by varying degrees of soil salinity. Climate refugees have been created and many people replaced their indigenous habitat and profession. Many people became homeless. Like human beings wild animals also try to replace their habitat. Over 1.6 billion people’s lively hood depends on forest and 30% of forest are used for production of wood and non-wood products. The appropriate plantation projects and studies have been taken in consideration on conservation of coastal ecosystem, wild lives, protection of soil erosion, controlling of the desertification, reducing carbon emission, employment, poverty alleviation, and improvement of socio-economic condition for sustainable development and to mitigate the challenges. Thus it will be automatically revival of the forest and reduce the disaster and other natural calamities from the coastal regions of Bangladesh.
