Climate induced changes such as extreme cyclone, devastating tidal surges, severe floods, tremendous river erosion, excessive rainfall, overwhelming salinity intrusion etc, are occurring more frequently in greater intensities and in an unpredictable manner around the world. The research focuses on the perception level of the people on climate change vulnerability and its impact on their livelihood patterns. The research revealed that various climatic events adversely affect the people of the study area. Among all natural disasters, cyclone affects severely the livelihood pattern of the study area. Peoples of the affected area experienced that disproportionate rate of salinity intrusion into the land mass increased less fertility that causes failure of crop production. As a consequence, most of the low income families are now facing food insecurity and a huge amount of potable water crisis that makes the people more vulnerable along with a threat of different water borne diseases. Finally consideration of the mentioned vulnerable factors, a simplified adaptation strategy based on the respondent view is recommended.
