Practical risk and resilience assessment: a methodology for implementation of Mountain Risk Management and Prevention Strategy (STePRiM)
Résumé
Mountain territories are highly exposed to natural phenomena which threaten people, assets and infrastructures. Those phenomenona induce both direct consequences (damage) on objects but also indirect consequences due to critical infrastructures failures. For instance, road closures due either to rock falls, floods, snow avalanches, landslides will have long-term, remote, economic, social consequences which somehow characterize the territory resilience. To reduce risk, local authorities, State, infrastructures managers combine structural and non-structural measures such as protection measures, land use control plans, preventive information. In this context, challenging decision-making issues appear to define and choose the best measures and strategies for a given territory. The French ministry for Ecological Transition (directorate for risk prevention) (MTE/DGPR), responsible for risk management, has designed and proposed a new innovative framework to help local authorities choosing and also funding their risk management strategies in mountain areas (STePRiM : Mountain Risk Management and Prevention Strategy). It consists in a first step of risk diagnosis followed by a step of prioritization between possible options. Due to large-scale assessment, it remains difficult to carry out detailed and complex risk and resilience analysis for all sites. A specific, incremental methodology is required. This paper describes a practical methodology and emphasizes constraints and requirements for practical resilience analysis. Based on the example of CCPHG, it first recalls how risk and resilience concepts are communicated with technical experts and stakeholders. It then describes how direct and indirect risks are addressed in a consistent but pragmatic way. Results are provided in order to be used and connected with the decision-aiding processes involving stakeholders and considering their preferences and priorities.
