Impacts of climate change on human security in Bangladesh: a systematic map

Bangladesh is considered a climate hot spot for its unique geography, high population, poor infrastructure, high inequality, corrupt governance system and heavily agriculture-reliant economy. Due to its physical location compounding extreme weather events like cyclones, floods, heat waves, extreme rainfall etc. are a yearly phenomenon and climate change is contributing to their increasing frequency and intensifying severity. The impacts of such natural hazards then start a cascading process within the interconnected sectors of the society and affect different dimensions of human security, leading to multiple system failures, where the poor are hit disproportionately. Plenty of research is done on climate change impacts in Bangladesh, but there is lack of aggregated research that combines this evidence and provides a comprehensive overview of the systemic risk. The objective of this study is to investigate the existing literature on how climate change along with interdependent dimensions of the societal system pose threat to different components of human security. The concept of human security used here is based on three pillars: freedom from fear, freedom from want and freedom to live in dignity. A systematic map approach is adopted to ensure minimal human and publication bias as opposed to a traditional review process. Standardized key terms were used to search literature in Web of Science and broad inclusion criteria were applied for screening relevant papers. Selected papers will go through a robust coding process to create an exhaustive database and yield the complex pathways of interaction between climate-related extreme weather events and human security in Bangladesh.
