Jan-Feb 2018 | Dhaka
Dhaka, the capital of Bangladesh, is perhaps most associated with these words: overpopulation, traffic congestion and waterlogging. While supporting more than 15 million people on less than 325 square kilometres of land, the city’s drainage and transportation infrastructure is on the verge of collapsing. Beneath the apparent reasons—overpopulation with a large number of informal settlements; waterlogging during the monsoon seasons; and traffic congestion on a daily basis—there is a major underlying cause: global climate change with its direct and indirect impacts i.e., sea level rise; saltwater intrusion; temperature variations; erratic rainfall; internal migration, etc.
In recent years, the casualties from climate-induced heat and cold waves have been observed frequently. Both heat and cold waves have a damaging effect on the human body, especially on the poor income groups, elderly and children.
