A UFZ study shows: If the population feels well informed, it has a more positive view towards nature-based flood prevention
In many places today, dikes are being moved back, and floodplains are being revitalized in order to give the river more space during times of flooding. This should make flood protection more effective and reduce the risk of flooding in inhabited areas. Nevertheless, natural flood prevention projects are often met with considerable resistance from the general population. Why is that? Researchers from the Helmholtz Centre for Environmental Research (UFZ) and the University of Potsdam have investigated this question in a social science study. They found that fear, personal experience of flooding, and a lack of information play a particular role in this. According to the research team, when flood protection measures are planned, the general population should be involved and informed as early as possible. The study was recently published in Risk Analysis.
There have been repeated flood disasters in Germany in recent decades. For example, in 2002 and 2013 along the Elbe and in 2021 in the Eifel region. As climate change progresses, severe floods are expected to occur more frequently. It is therefore important to quickly implement effective protection measures in vulnerable areas.
