A devastating storm hits two regions with equal intensity. In one, few people die. In the other, many die. Why? The answer lies not solely in the occurrence of such climate disasters.
Researchers at the University of Leipzig analyzed more than 7,000 climate disasters between 1990 and 2020. According to the study, whether people survive a flood or a hurricane depends not only on the severity of the event, but also on how good the living conditions are in their region.
What Needs to Be Done Now
In many parts of the world, vulnerability has decreased in less developed regions over the past decades because living conditions have improved. Investments in education, infrastructure, and disaster preparedness can significantly reduce the consequences of extreme events.
“According to forecasts, climate hazards will continue to intensify in many parts of the world,” says Prof. Dr. Melanie Krause, who contributed to the study from a socioeconomic perspective. “However, their humanitarian consequences are not entirely predetermined. Investments in human development, infrastructure, and preparedness in general can save lives.”
According to the researchers, it is important to know more precisely which regions are particularly at risk from climate-related disasters. This could help better protect people from the consequences of extreme weather. The Leipzig Institute for Meteorology, the Faculty of Economics, and the Helmholtz Centre for Environmental Research (UFZ) also participated in the study.
