**4. Conclusions**

The currently existing challenges of climate change has been unanimously recognized by the international community, as a result of which Bangladesh, small country in terms of territory, ranks high in the list of most vulnerable countries on earth- as stated. The geographical characteristics of Bangladesh are heavily dependent on local and regional hydrological characteristics, which rely on climatic processes incusing dimensions of seasonality. Despite being a nano-emitter of the harmful greenhouse gases that contribute to increase the global average temperature, Bangladesh is the hardest hit as a result of climate change impacts. Larger and more integrated and innovative solutions are required to truly tackle the problem. Being one of the most climate vulnerable countries in the world, Bangladesh is at risk of natural disasters such as riverine and flash floods, tropical cyclones, storm surges, droughts, salinity intrusions, sea level rise and riverbank and coastal erosions. The trend analysis in this study shows that the changing patterns of temperature and rainfall of the country has a number of implications on agriculture and food security, water sector, health sector, livestock and fisheries and overall livelihood of the communities. Both the rural and the urban sectors are affected due to the unpredictable implications within these sectors. The effects of climate change are ubiquitous and all encompassing, causing the magnitude, frequency and duration of such natural disasters to increase, thus making marginalized communities extremely vulnerable. While the country has made a number of significant progress in reducing death burden from natural disasters, the remaining challenge is to protect the livelihoods which push people below the poverty line, force them to

migrate to the urban areas in search of work and also excludes them from a rightful participation in shaping the local level decision-making and service provisioning in favor of them. To that, this study concludes that further data science applications to socio-environmental studies like these should be in continuation for deeper assessment of vulnerability assessment to take right national and global policy uptakes.
