Démarche d'analyse et de diagnostic du risque de glissement de terrain : de l'identification à une mesure proactive

Abstract

In the context of the worsening of the major natural hazards induced by urban growth, societies must respond more to the challenge of developing prevention tools. As underlined by the International Strategy for Disaster Reduction, participatory methods, based on the sharing of information and the transmission of knowledge on risks are acclaimed. We present here an approach to acquiring knowledge on natural and human dynamics in a territory subject to landslide risk for the purpose of transmitting a practical risk culture. This approach, developed through action research, generalized in a model, was applied to three landslide risk areas. Based on the similarities and contrasts in the perception of risk by the populations, ideas for improving prevention are proposed at the same time as the action-research posture to treat major risks is discussed.
