In 2024, disasters displaced 2.4 million people within Bangladesh even as the International Monetary Fund predicts that rising seas could eliminate more than one-seventh of Bangladesh’s land area and nearly one-third of its food production by 2050. As environmental pressures drive people from their homes, researchers are examining the risks migrants face in the secondary cities where they relocate and whether these cities are equipped to accommodate growing numbers of climate-displaced people. To cope with increasing climate-related pressures, migration is often viewed as an adaptive strategy because moving away from areas exposed to hazards such as flooding, cyclones, river erosion and sea-level rise can help people reduce their exposure to climate risks and seek safer housing and more stable livelihoods. In these circumstances, urban informal settlements are often among the first destinations for displaced people. Yet, in Bangladesh, these settlements are risky in nature because of the structural formation, and the residents are exposed to various hazards. This raises a broader question: Are the cities receiving climate migrants equipped to support a safer, more stable future or leaving them more exposed? A new study published in Climate and Development on climate migrants living in informal settlements in southwestern Bangladesh examines what happens to migrants after relocation to secondary settlements. The study findings suggest that moving away from regions affected by climate hazards does not necessarily mean moving toward safety, particularly when urban planning and social protection systems fail to account for their needs.

One afternoon earlier this year, Mridula collapsed on the floor of the Dhaka garment factory where she works, overcome by dizziness in the heat. The 20-year-old sewing operator, who works at a factory in Mirpur, northwest Dhaka, said summer heat often leaves her restless and “physically uncomfortable.” “The heat can be very difficult to tolerate,” said Mridula, a pseudonym. Co-workers with high blood pressure seem to struggle even more during the hotter months, she has noticed. After she collapsed, she was taken to the factory’s medical room. She said the doctor told her to rest, then sent her home. “He gave me leave from work,” she said. Mridula was eventually diagnosed with jaundice, which can be exacerbated by dehydration and physical exertion. As temperatures climb, heat is becoming a serious concern for Bangladesh’s garment industry. Dhaka’s summers are setting new records. On April 15, 2023, the city reached 40.6°Celsius (105° Fahrenheit), then its highest temperature in decades, according to World Weather Attribution. Then, the following year, the country sweltered through a heat wave that lasted 30 days without a break. A 2025 report by the World Bank shows that Bangladesh’s maximum temperature has risen about 1.1°C (about 2°F) since 1980. Meanwhile, researchers are increasingly concerned about the health and economic consequences of rising temperatures, particularly for workers exposed to prolonged heat. For Bangladesh’s 4.2 million garment workers, approximately 60% of whom are women, who work indoors, rising temperatures raise urgent questions about occupational health and workplace safety. Factory workers operate…This article was originally published on Mongabay
