La perception du risque de coulées boueuses : analyse sociogéographique et apports à l'économie comportementale

Abstract : Alsace is one of the French regions the most affected by muddy floods. The urban occupation, physical and agricultural characteristics promote their formation (loamy soils, large crops areas). Our reflection contributes to answer to the contribution of taking into account levels of risk perception by stakeholders to determine / modify their behaviour, and to improve policies to reduce risk by insisting on the expectations of population. Eleven Alsatian municipalities were chosen to be surveyed about the perception and representation of the risk of muddy floods. The method developed four objectives: (i) allowing a detailed analysis of the behavior of population concerned by this risk, (ii) provide data for improving economic behaviors' models, (iii) taking into account degrees of risk perception to improve the definition of preventive campaigns, (iv) creating a comparative mapping of variations in risk perception and “real” risk situations." Our results show that the risk perception varies depending on the concerned population, its involvement in the risk management and the level of damage incurred. The economic approach insist of the use of important factors (experience, threat of the risk, etc..) in modelling of individuals' behaviors facing natural hazards.
