Abstract
The assessment of environmental damages is increasingly challenging, to the level that it has lately affected some events, brought to the consideration of the public opinion. From the perspective of the authors, although the Italian law has been appreciably developed, the calculation methods for reparations have never evolved in a significant way. That is why they cannot be considered as suitable: they only consider reclamation costs, significantly downplaying the outcomes that add several negative side-effects, related to the actual unfeasibility of restoring the present condition to the configuration that it used to have before the harmful events. To solve this problematic node, the authors reviewed an “old” approach to the damage assessment (dividing it into hazard, vulnerability and exposure factors), combining it with the sustainability concept assumptions, a scenario analysis procedure and the use of GIS tools, that enable the user to draw the framework to be analyzed in a user-friendly way. The result is a prospective and comparative evaluation of the reduced capability of the environment to support the activities of its three components and of the assessment of “value parameters”, that will be calculated outlining the rareness of each ecosystem and the actual inability of restoring its initial configuration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
