Vulnerability of human environment to risk: case of groundwater contamination risk

Based on a theoretical revision of the social vulnerability concept, this article proposes a scheme of vulnerability indicators within the human environment focused on different aetiology risks. An adaptation of this generic scheme of vulnerability factors is set for the specific field of aquifer contamination risk, as well as a methodology for its analysis. Finally, model application examples are given for the Sierra de Líbar and Sierra de Mijas carbonate aquifers and the Vélez River detrital aquifer, all of which are located in the south of Spain. Obtained cartography results show a range of utilities for risk mitigation and permit appropriate spatial discrimination for its performance over different scales. The exposure and vulnerability of the groundwater contamination risk concept is evaluated in specific maps, taking into account the resident population as well as their assets.
