Climate Change and Displacement in Bangladesh: Issues and Challenges

The purpose of this chapter is to explain and understand the causes of forced resettlement and climate change caused by climate change in the present era of globalization. Increasing the impact of the environmental crisis and climate change in Bangladesh is an important reason for cross-border migration to South Asian countries. This chapter focuses on Bangladesh's immigration and climate change issues. Research is based on theoretical sources and empirical data. The outcome of population migration in the context of South Asia will destabilize the impact of socio - political, economic and climate change in the future. Bangladesh is often regarded as one of the most vulnerable countries on the planet and will become more and more nervous due to climate change. In this chapter, we emphasize that climate change is not a phenomenon to be resolved at some point in the future but a crisis in progress in Bangladesh. Coastal region sea level rise and tropical depression, as well as the mainland floods and stream erosion, coupled with national socio-economic conditions have led to the loss of extensive housing, land and property in Bangladesh. Among the many causes of population vulnerability, cross-border immigration caused by climate change may increase the sensitivity of South Asian countries to climate change. This chapter will detail the legal framework on current and future causes of climate change in Bangladesh. It also analyzes existing government policies and plans to provide solutions to climate change and emphasizes the need to use rights based solutions as the basis for dealing with this crisis.

Climate change in Bangladesh is an urgent task. According to the geography of the country, Bangladesh is one of the most vulnerable countries against climate change. Bangladesh is located in the tropical region of cancer and receives considerable direct radiation throughout the year and maintains a relatively high temperature. Bangladesh is located at the bottom of the Ganges River, Brahmaputra River, Megner (GBM) River System. There are 57 transbound rivers in Bangladesh of Bangladesh. It is 54 from neighboring India and 3 from Myanmar. This country can not control the flow and flow of water, it flows to the Bay of Bengal. Together with widespread poverty and population growth, limited adaptability, insufficient funds and insufficient local governments, this region is one of the most seriously affected areas on the planet. Estimated 1,000 people per square kilometer, annual population increases by 2 million people

In Bangladesh, climate change will start and there is a possibility that it will be the largest population movements in human history. In recent years, 50,000 to 200,000 people evacuate every year due to river bank erosion. The island of Bangladesh is called the "immediate threatened" island called "role" and the population exceeds 4 million people. When the sea level rises 3 feet, about 20% of the country is flooded and more than 30 million people evacuate. Some scientists predict that they will increase by 5 to 6 feet by 2100, but this will replace approximately 50 million people. From a certain point of view, the tragedy occurring in Syria caused about 3 million outflows.

Due to conflict, drought and climate change more refugees were born. More than 4.8 million people fled from Syria. In Bangladesh, 200,000 people lost their homes every year due to river erosion. An average of 26.4 million people evacuate each year due to disasters, but as weather gets more frequent, this number surely increases.

Bangladesh's view on climate change and its possible security implications: Bangladesh is recognized as one of the world's most vulnerable countries for global warming and climate change. This is due to its unique geographical location, benefits of flood plains, low altitude, high population density, high levels of poverty, and overwhelming dependence on nature, resources and services. The history of abnormal weather in this country has deprived millions of lives and has destroyed the development of the past. Changes in rainfall patterns have hampered people who rely on farmers and meaningful income opportunities, coupled with an increase in snow melting from Himalayas and extreme temperatures leading to damage and failure of the crops. In the changing climate, the impact model erodes our assets, investment and the future. This represents families, communities, and countries. The following effects have been observed
