Consequences of Natural Calamities on GDP Growth Rate of Bangladesh

This study is highly influenced by different seasonal climatic variables such as high fluctuations of day and night temperature, changing rainfall pattern, high carbon dioxide concentration, humidity, day-length etc. It is also constrained by different climatic disasters such as floods, droughts, cyclone, storm surges, sea level rise etc. Potential increase in global temperature due to climate change and population growth and their impact on rice productivity, above all food security, has been a major concern in recent years. Population growth rate in Bangladesh is two million people per year and the population will reach 233.2 million by 2050, going by the current trend. Global warming has been an issue lately in many aspects because it has been in increasing trend since 1980s. Climate change might be a major concern to humidity, temperature, rainfall since it affects many economic sectors as well as different aspects of human life. Negative impacts of climate change on agricultural sector will be especially dangerous since agriculture is directly related to food security and human life. This paper analyzes the impact of climate change on agricultural production in Bangladesh from 1970 and 2012. This study estimates a country-level fixed effect (FE) panel model for agricultural production using seasonal climate variables and other input variables. The results show that higher temperatures and more precipitations in summer increase agricultural production while higher fall temperature is harmful in Bangladesh. On the other hand, overall increase in annual temperature decreases agricultural production in Bangladesh
