Local, indigenous knowledge should be incorporated into future decisions.
A lot of indigenousknowledge, especially in rural areas, has been lost. This historic knowledge is very important. In low-lying areasin pre-alpine hills in southern Baden-Wu?rttemberg, historic buildings have strongly fortified basement andground floor levels – a construction-based adaptation to the flood hazard. In the past, there was an awarenessthat the stream could burst its bank in certain seasons and people were willing to endure certain sacrifices tocomfort, such as temporarily closing openings in lower floors. This culture of adaptation has unfortunately beenlost. Historic traditions cannot be revived exactly as in the past, but they illustrate how creative solutions couldreduce risks today.
