Impact of Sea Level Rise in the Coastal Areas of Bangladesh: A Macroeconomic Analysis

Abstract

Due to diverse economic activities (mainly burning of fossil fuel), carbon dioxide (CO2) and other greenhouse gases (methane, nitrous oxide, ozone, chlorofluorocarbons and water vapor) are accumulated in the earth’s atmosphere, resulting in climate change. Rising temperature expand the ocean volume in two ways. Firstly, it melts mass volume of ice of the polar region and secondly, it causes thermal expansion of water of the ocean (L.Hossain& k.Hossain,2005). Ongoing climate has a greater socio economic and environmental impact on different countries. Bangladesh is considered as one of the most vulnerable countries due to climate change. Among the adverse effect of climate change, it is evident that Sea level rise is the major concern for Bangladesh which can bring a higher cost for the entire economy of this country which is difficult to capture in monetary term also. In this study the exertion is given to analyze the ongoing and long run effect of sea level rise in the coastal areas of Bangladesh. It deserves special mention that the affected districts those who are impacting by the sea level rise will spread out the cost in entire economy in the form of climate migration in cities, regional food insecurity, and poverty.
