^aBased on the outcomes of the literature survey, expert consultation and data availability; ^bRefers to the spatial resolution of the original datasets (i.e., before the data was resampled to 10x10 km² grids); ^cSign indicates if high indicator values increase (+) or decrease (-) vulnerability; ^dThis indicator was removed from the analysis to reduce existing multicollinearities in the data.
