At: International Mountain Conference ; Innsbruck : 8.9.2019 - 12.9.2019 ; This poster presents the integrated risk assessment methodology used in the GreenRisk4Alps (GR4A) project. GR4A is an Interreg Alpine Space project aimed at integrating ecosystem-based solutions into risk reduction strategies in the Alpine area. In order to understand the benefits associated with ecosystem-based solutions (e.g. protection forests), natural hazards, elements at risk and the possible effects of protective measures need to be studied encompassing a risk assessment process. The methodological framework used in the GR4A project follows a stepwise approach that allows for different depths of analysis. Its objective is to integrate qualitative information collected from stakeholders with data obtained from hazards modelling. The process starts with a “Rapid Risk Appraisal”: a participatory process for stakeholders which provides a quick and general overview of the main perceived risks. The developed risk profile constitutes the basis for the subsequent development of “impact chains”, a tool that helps to elaborate cause-effect relationships through the determination of hazards, intermediate impacts, vulnerability and exposure of the system. Such a schematic representation of the system serves as a basis for further and more detailed analysis and it allows to identify entry points for risk reduction measures. Once interrelations and feedbacks are visible, it is envisaged to perform a more detailed and spatially explicit assessment incorporating quantitative data. Major challenges that emerged referred to finding the balance between rapidness of information acquisition and the explanatory power of subsequent results. Furthermore, the integration and visualisation of data and results was experienced to be a critical task.
