Abstract
Climate change is a contemporary global threat to the whole world especially in the coastal area like Bangladesh. Bangladesh is extremely vulnerable to climate change impacts because of its geographical location. This research is an attempt to assess the impacts of climate change on fishersʹ livelihood of a selected climate hotspot zone Munshiganj. In the study area, the average sex ratios of male and female were 56.67% and 43.33%, respectively and their religion ratio were Islam 45% and Hindu 55%. There was 60% nuclear family and 40% joint family. About 86.4% house was tin-shed and drinking water source was only tube well. In Munshiganj, 11% fishers were illiterate, 27% had primary, 38% had secondary, 16% had higher secondary and 8% had bachelor. Most of the people about 59% were depended on Upazila Health Complex for their health issues. Highest percentage of fishers about 40% had an annual income of 20,001 to 24,000 BDT. About 62.7% fishers were agreed with the statements: reduce fish production, damage fishing ground, blockage of fish migration road, damage biodiversity, increasing temperature, enhance soil erosion, reduce rainfall, siltation, water flow, storm frequency, changing spawning season, decrease fish production, extinction fish species. In study area, women and children are affected severely i.e. malnutrition, education, treatment, early marriage etc. The present study clearly indicates that there are visible changes in livelihood condition of fishers‟ in the study areas of Munshiganj.

Summary
Climate change has become a much-discussed issue in the world and it affects the global environmental system. Bangladesh deals with the effects of climate change because of the all too loud alarm bells sounded in recent times about the dangers to which the least developed countries of the world are exposed. Climate-related factors will result in losing the means of livelihood of 40 million people in Bangladesh, with the additional fact of 20 million more being displaced by 2050 owing to natural calamities generated by climate change. One severe effect of climate change will be people getting uprooted from their land and finding themselves in the unenviable position of having turned into climate refugees. Climate change arises from past and present emissions of greenhouse gases increasing pre-existing concentrations of these gases in the atmosphere (IPCC, 2007a).
