Climate change is threatening socio-economic sectors, such as tourism, agriculture, energy, as illustrated in the Italian Adaptation Strategy.

The aim of this work is therefore to assess the vulnerability degree of potentially climate sensitive sectors for the Marche region (Italy)

The methodological path was based on the Guidelines produced within the LIFE SEC-ADAPT project, coordinated by Sviluppo Marche the Regional Development Agency of Marche Region in the framework of the European Initiative Covenant of Mayors for Climate and Energy, and illustrated in the document “Methodology for vulnerability and risk assessment in Marche and Istria regions” (LIFE SEC-ADAPT Project, 2017). In turn, the guidelines follow the approach proposed by GIZ et al (Fritzsche et al., 2014) in the document “The Vulnerability Sourcebook – concept and guidelines for standardized vulnerability assessments”.

According to the above mentioned documents, the approach aimed at the quantitative evaluation of exposure, sensitivity and adaptive capacity of the different sectors to the impacts of climate change in order to determine the vulnerability level of each sector. Specific indicators were therefore selected, evaluated, weighted and aggregated for this purpose.

The proposed methodology requires a large amount of data for different social and environmental sectors to which it was applied: Land, Health, Coastal Zone, Agriculture, Tourism, Biodiversity and Infrastructures, in order to obtain information on the degree of susceptibility to climate change, including extreme events.

The methodology used does not fully describe the complexity and especially the interaction of several phenomena but it is suitable for use in cases where the phenomena can be described through linear paths (i.e. to a cause corresponds to an effect). For this reason some simplifications were adopted in order to describe phenomena which are really much more complex. However, this approach could represent an accessible tool for regional and local administrations to get a first outlook about their priorities in order to face the challenges posed by climate change.

The analysis of the vulnerability associated with the risk analysis provides the fundamental elements on which to establish the priorities for intervention in terms of adaptation to climate change.

This type of application has provided for the first time relevant information on the current critical areas of the Marche region and socio-economic sectors considered to be among the most sensitive to climate change.

Furthermore, the methodology made it possible to compare the municipalities of the Marche region on the basis of specifically selected indicators.

The analysis made it possible to reflect on the preparation of  future policies to adapt to climate change in the various sectors analyzed in the Marche region.
