Psychosocial Damage After Flood Events
After extreme floods, there are almost always significant psychological and social impairments that can range from the endangerment of social ties to prolonged depression. This type of pollution has not yet been adequately taken into account in the decision-making process on flood protection measures. In order to be able to integrate psychosocial damage into a multi-criteria decision support system, however, it is necessary to first quantify this damage. This can be done by means of a vulnerability analysis, which takes into account individual and socio-spatial parameters.
In the event of failure of protective measures, the extent of expected psychosocial damage depends on the precautionary measures planned and implemented by the decision-making authorities within specified structures; in addition to voluntary individual precautions, the vulnerability of residents in a geographically demarcated area plays an important role, which is determined, among other things, by psychosocial characteristics such as age and gender.
An empirical investigation of potentially affected persons as well as an analysis of the decision-making structures should contribute to the development of risk and vulnerability assessments, which should lead to the optimization of decision making processes.
