Landowner’s perception of flood risk and preventive actions in estuarine environment: An empirical investigation

Abstract : Within Europe, flood and coastal risk management is undergoing a major paradigm shift as it moves from an approach dominated by investment in flood defence and control infrastructure to another one in which non-structural measures are favored. One research challenge consists in developing a better understanding of local population risk perception and its effects on prevention and preparedness actions in order to improve social acceptability of adaptive flood risk management. Landowners’ involvement in wetland management offer benefits beyond the line of their property. Accordingly, the purpose of this study is to achieve an empirical understanding of risk perception and self-protective behaviour among the landowners of the riparian marshes in the Gironde Estuary, in France. Application of the psychometric approach reveals that flood risk perception among landowners can be characterised by three synthetic variables that indicate on the degree of exposure, the sense of control and knowledge of the risk. Examining the relationships between these perceived risk dimensions and landowners’ participation in water structures management provides three profiles of self-protective behaviour distinguishing “vulnerable”, “autonomous”, and “passive” individuals. Finally, implications of our findings for the region under study and for more general concern are discussed.
