Professor Dr.-Ing. Jörn Birkmann from the Institute of Spatial and Regional Planning (IREUS) of the Faculty participated in a public expert discussion of the Committee for Housing, Urban Development, Construction and Municipalities of the German Bundestag on July 6, 2022. The topic of the expert discussion was "Lessons from the flood disaster - reconstruction and sustainability for the affected regions." Birkmann called for all known information to be better incorporated into strategic decisions in the future. "We need to consult hazard and risk maps more closely when making strategic decisions about investments and pay better attention to different levels of protection," he said. On the other hand, he said, we need to get away from the idea that we can keep water out of such valleys or that we know exactly where the floodplains are.
