Social vulnerability (re-)assessment in context to natural hazards: review of the usefulness of the spatial indicator approach and investigations of validation demands

While social vulnerability assessments (SVA) use spatial indicators and indices that have become state of the art, they also receive substantial critique. This article analyzes, by means of a literature review of 63 articles, if and in which aspects such an indicator approach is regarded as useful by scientific studies. The findings indicate a need for more research on the validation and justification of indicators. This article supports the conceptual development of SVA by adding to reflection about advancements and applications, but also shortcomings. The main advancement area discussed is validation and the demand for establishing benchmark criteria for vulnerability. Based on this, longitudinal monitoring of vulnerability and validation studies are conceivable based on existing SVA, but these efforts demand more conceptual development.
