The need for information has for long been acknowledged as a major issue to cope with flood situations. Consequently a huge number of printed or electronic documents are accessible. They for instance deal with before-during-after flood situations or vulnerability assessment/reduction. Is it enough to have such easily available information to build prevention, adaptation, protection capacity? Is this information known? Do we know how this information is used? By whom? What for? Is this information pertinent for concerned people? In order to examine these questions, CSTB carried out a qualitative inquiry by a panel of stakeholders in two French regions (Ile-de-France around Paris and Languedoc- Roussillon in the south). They are both vulnerable but Paris has a faint memory of flood-risk while the memory in Languedoc-Roussillon is frequently revived by flood events. This action was based on published documents (both printed and electronic) concerning after flood repair and vulnerability assessment methods. The survey was carried out according to a classical method in environmental and social psychology. We met (1) stakeholders belonging to public bodies known to actively disseminate these documents and (2) stakeholders who were not recipients of these documents. The first results of this enquiry demonstrate that: • vulnerability reduction is an emerging issue for French local authorities. • more targeted information according to stakeholders groups is needed. • a territorial approach in risk assessment and vulnerability reduction is required. • the acceptability of the risk, which varies depending on several variables, must be acknowledged. • the capacity to adapt the content of documents to local territorial contexts must be developed. • tools of communication are not effective enough to inform or to raise awareness; it is necessary study the condition of their appropriation. • the culture of flood risk must be elaborated with consultation strategy, by associating concerned stakeholders (public, professional, political, technical, etc.).
