Abstract

In light of increasing losses from floods many researchers and policy makers are looking for ways to encourage flood risk reduction among communities, business, and households. In this study we investigate risk reduction behavior at the household level in three European Union (EU) Member States with fundamentally different insurance and compensation schemes. We try to understand if and how insurance and public assistance influence private risk reduction behavior. Data was collected using a telephone survey (n=1,849) of household decision makers in flood-prone areas. We show that insurance overall is positively associated with private risk reduction behavior. Warranties, premium discounts, and information provision with respect to risk reduction may be an explanation for this positive relationship in the case of structural measures. Public incentives for risk-reduction measures by means of financial and in-kind support, and particularly through the provision of information are also associated with enhancing risk reduction. In this study public compensation is not negatively associated with private risk reduction behavior. This does not disprove such a relationship, but the negative effect may be mitigated by factors related to respondent’s capacity to implement measures or social norms that were not included in the analysis. The data suggests that large-scale flood protection infrastructure creates a sense of security that is associated with a lower level of preparedness. Across the board there is ample room to improve both public and private policies to provide effective incentives for household level risk reduction.
