Climate change affects increasing urbanisation: Study UNB 19th May, 2021 07:00:21 Air density of Dhaka’s two of the most marginalised low-income slums is four to five times higher above the permission limit of Bangladesh for 24 hours. As a result, residents suffer with air pollution induced diseases like laryngeal problems, asthma and bronchial problems. A study report published Wednesday titled “Urban Localized Pollution in the Context of Climate Change” revealed such information during its virtual launching and discussion event. According to the study report, the major source of indoor air pollution in both the marginalise areas are earthen stoves for cooking, using biomass as fuel. Women are the most severely affected by air pollution as they are exposed to smoke for long stretches of time during cooking.
