    Effects of climate change variables on under-five child stunting in Bangladesh
    (BRAC University, 2023-09) Khan, Tausif Amin; Shafiullah, Muhammad
    This research paper explores the impact of geospatial variables and sociodemographic factors on child stunting in Bangladesh, using data from the 2014 wave of BDHS (Bangladesh Demographic and Health Survey) and climate data from Bangladesh Meteorological Department (BMD) spanning 2009 to 2013. It was found that the average age of children under 5 in the sample is approximately 29 months (about 2 and a half years), with mean weights and heights slightly below the expected values. The climate data indicates that Bangladesh experiences mean maximum temperatures of over 34°C and mean minimum temperatures of around 21°C, with a relatively high average relative humidity of 79%. Rainfall averages 738.6 mm (about 2.42 ft) across divisions with low variability. Visual analysis shows that temperature has a limited impact on children's height, while higher relative humidity and rainfall are linked to height stunting. Regression analysis confirms these findings, revealing that increased relative humidity negatively affects the Height-for-Age Z-Score (HAZ) by nearly 2 percent, while rainfall has a minimal to no impact on HAZ. Male children have a 12 percent higher HAZ, and higher parental education and family wealth positively influence children's HAZ scores. These results contribute to our understanding of the factors influencing child stunting in Bangladesh and emphasize the importance of addressing both climate-related variables and sociodemographic factors to improve children's nutritional outcomes.

    Quantifying the direct economic damage caused by the impact of climate change in Asia Pacific Region
    (BRAC University, 2022-01) Safi, Safwan Mahmood; Khan, Wasiqur Rahman
    Global warming or climate change has amplified the number of natural disasters around the world. Natural disasters include floods, various forms of storms, cyclones, heat waves, drought, wildfires etc. Two important indicators of global warming or climate change are rise in average global temperatures and variability in global rainfall. This paper examines the anthropogenic link between global GHG emissions and climate change indicators (temperature and precipitation levels) and natural disasters. The Asia Pacific region has experienced the brunt of these natural disasters in recent decades and is counting billions of dollars in direct economic damage. Could there be a relationship between the aforementioned changes in climate and the rise in natural disasters in the Asia Pacific region? This paper looks at two important climate change indicators (temperature and precipitation) and tries to quantify the value of economic damage caused by the disasters annually. In cointegration analysis under ARDL framework, there is a long-run association between the increase in direct economic damages in USD and climate change indicators. Global average temperature shows a positive and significant impact on economic damages. Furthermore, inspection of the short run relationship in an ECM model also displays a positive and significant relationship between one lag period of global average temperature and economic damage values. Granger causality examination corroborates the findings and reports a uni-directional causality running from global average temperature and economic damage value. In conjunction with evidence from the literature that it is “very likely” that increases in global temperature, caused by increasing release of GHG in the atmosphere, is altering the climate system suggests a connection between economic damage caused by the natural disasters observed in the region and global warming.
