Abstract

One of the most significant impacts of climate change is sea level elevation which affects coastal nations such as Bangladesh. It occurs mostly due to the melting of glaciers caused by global warming. Therefore, Bangladesh faces a noticeable amount of damage and loss in coastal regions due to sea level rise. This Study will analyze historical data to determine the relationship between sea level rise, settlement and cropland loss and economic damage and predict its effects on the coastal regions of Bangladesh in the coming years. This study utilizes a secondary dataset collected from the Ministry of Environment, Forest and Climate Change for the years 1995 to 2024. The study emphasizes on sea level rise ranging from 32.18 cm to 995.07 cm, coastal settlement loss going from 74.51 ha to 981.79 ha, agricultural land loss extending from 34.76 ha up to 964.49 ha along with economic damage from 25.27k USD to 977.07k USD. Descriptive Statistics, Correlation and Trend Analysis and impact indexing was applied to summarize data, identify relationships, predict future conditions and identify major impact years along with probable alarming thresholds. The study showed, not only sea level rise but also people's residential and cultivation pattern contributes to the loss of land and property. Additionally, moderate economic loss along with higher settlement loss indicated better precautionary strategies. Furthermore, higher farmland loss contributed to higher economic loss. Hence, to prevent these losses, reinforced coastal safeguard is essential to preserve the environmental and economic development along the coastal territories of Bangladesh.
