Essay On Natural Hazards In Bangladesh

Natural hazards like tropical cyclone and storm surges, riverbank erosion, flood, as well as landslide and drought are regularly happened in the coastal area of Bangladesh because of its unique position. In fact, Bay of Bengal is the perfect breeding ground for the tropical cyclone. Low altitude with gentle slope and funnel shape characteristics near the adjacent seashore gives a way to create bigger storm surge in the coastal inland area. Since soil of this area has muddy characteristics, mud flow is created near the foothill during monsoon period that known as the landslide. These hazards make the life of people miserable along with damaging the infrastructures and break down the economic progress. According to the assessment of Intergovernmental Panel on Climate Change (IPCC), small island states, as well as coastal regions which have low altitude, are vulnerable position as rising of sea level directly threat to their existence. Bangladesh is the topmost country

Among them, more than 55% live within 100 km of 710 km long from the coastal belt [5]. Most of the people always fight with poverty as their livelihood generally depends on weather and natural resources. And this type of people specifically exposed to the threat of cyclones and storm surges. Bangladesh has 12 out of 19 coastal districts directly exposed to the sea [5]. Because of that reason, large-scale displacement occurred during the period of natural hazards.

In recent years, Bangladesh experienced the fury of nature. More than 6,500,000 people were displaced and killed 3,447 by Sidr in 2007 [6] and around 4.82 million affected by the cyclone

Aila [6]. Cyclone Roanu that hit the coastal belt in 2009, forced 2 million people to flee from their houses [7]. Cyclone Mora, which happened in the last year, displaced more than 5 million people from their homeland [8]. Along with displacement, causality factor was also
