Social and institutional factors often form strong barriers to the successful implementation of flood risk strategies. Good governance supports a better implementation of flood risk management strategies. In order to increase the resilience of urban regions against flooding, governance needs to support the application and adjustment of multiple strategies simultaneously.
Even in regions where a good flood defence system is in place, flooding may occur. The region is more resilient against flooding when critical buildings and infrastructure are built higher grounds, people from the lower grounds are evacuated in time, people have insurance to compensate material damages, etc. Such a situation can be compared to the situation in a car, in which the risk of an injury after an accident is managed not only by good breaks, but also by seatbelts, airbags, insurance etc.
At the same time, flood risk governance needs to be appropriate. It needs to be tailor-made to the opportunities and constraints of the physical and social context in a country or region and give evidence of being legitimate, efficient and effective . For example, flood prone regions with many residents and a high economic value, may need to be protected by strict legal safety norms. Furthermore, these safety norms need to fit in the legislative system of the country.
