While quantitative measures of vulnerability are widely used at different scales , there are also studies that caution the use of such indices in policy making or risk reduction efforts . Such assessments of vulnerability have to be internally and externally validated and handled with care when applied in decision-making processes in terms of their options and limits. At the same time, these assessments capture important conditions and structures that make people more susceptible to various climate hazards and climate change impacts. The relevance of these conditions is confirmed by quantitative impact assessments as well as many specific case study assessments . For example, the access to basic services   and broader modes of engagement in governance and governance fragility  significantly influence how climatic hazards translate into severe or non-severe losses and harm .
