Evolution of the chemical-environmental risk of territorial compatibility under the framework of the Seveso Directive: A case study of the autonomous community of Andalusia (southern Spain)

摘要

In this work, the evolution of the chemical-environmental risk oriented to the spatial planning in the autonomous community of Andalusia was carried out over the 2002-2012 decade. Indicators for determining the variables representing the risk, such as hazard, vulnerability and proximity, were then defined based on a consequence-based approach analysis risk methodology. A suitable mathematical combination based on spatial analysis methods supported by ArcGIS platform was also applied, which resulted in a quantitative and qualitative risk value and provided the territorial compatibility in the study area for each year. Finally, once the indicators that determine the risk level for 2002 and 2012 were obtained, they were combined in order to find out the risk tendency of the region for the whole decade.
