These were used input model, which applied outranking method rank most least vulnerable. Results generated partial rankings by components vulnerability, complete ranking that integrated components. results revealed main explained allowed typology helped prioritize interventions have greatest impact each municipality studied. Conclusions highlights importance considering multiple criteria their interdependencies when assessing provide tool support decision-making processes at level. is valuable prioritizing effective studied Key messages • developed provides robust processes.
