The SAMCO Web-platform for resilience assessment in mountainous valleys impacted by landslide risks.

Abstract : This study aims to develop a proactive decision support tool enhancing the overall resilience of societies coping with mountain risks. Methodological tools are elaborated and then implemented into a web-platform showing impacts of global change on mountainous ecosystems and society. Three representative case studies, located in Alpine or Pyrenean valleys, are investigated. The methodology is split in several points: (1) the definition of the potential impacts of global environmental changes (climate system, ecosystem e.g. land use, socio-economic system) on mountainous hazards, (2) the analysis of these consequences in terms of vulnerability (e.g. changes in the location and characteristics of the impacted areas and level of their perturbation) and (3) the implementation of a methodology for quantitatively investigating and mapping indicators of mountain slope vulnerability exposed to several kinds of hazard, and the development of a GIS-based demonstration platform available on the web. The strength and originality of our approach lies in the combination of different techniques, methodologies and models (multi-hazard assessment, risk evolution in time, vulnerability functional analysis, and governance strategies) that are implemented in a user-oriented web-platform. Conceptual architecture and main functionalities of the web-tools are presented and demonstrations are exposed for considered case studies in terms of multi-hazard maps and potential damage index for main stakes at risks. Analyses are presented for current and future periods for which climate change and land-use (economical, geographical and social aspects) scenarios are taken into account. This tool, dedicated to stakeholders, should be finally used to evaluate resilience of mountainous regions since multiple scenarios can be tested and compared
