The objective of this report ‘Climate risk assessment of the four regional hubs’ is to provide building blocks to finalise the risks assessment of the four selected hubs by characterizing the natural, socio-economic and structural features of the selected territories, namely their exposure and vulnerability to climate change hazards analysed in Deliverable 3.1. The process will allow to obtain risks profiles with the combination of the results of the previous report entitled “Climate Trends and Projections in the four regional hubs”, namely the key climate change signals, to vulnerability and exposure of the people in this area.
