Metodologia per la valutazione dell’impatto archeologico

The essay discusses the application of environment evaluation models, with regards to the Archaeological Component, in consideration of the rules in force for the protection and conservation of the archaeological heritage. The protection both of Cultural Heritage and of planning of infrastructures must follow the principles of «sustainable development». In the first part of the essay we acknowledge the value of environmental and archaeological impact studies on the territory. These studies, which must be conducted in a preliminary phase, make it possible to acquire a more profound knowledge not only of places subject to archaeological risk, but also of the historical and environmental reconstruction that may be useful for carrying out a project. The second part of the essay tackles the methodological problem for the archaeological impact evaluation of a site; this can be developed with the following aims: a) to single out the historical periods of a territory, relevant from the archaeological point of view; b) to define the sensibility of a historical period; c) to define the level of risk. For the evaluation it is necessary to define a qualitative hierarchy of the different sensibility levels that the archaeological object can have. This hierarchy is based on the identification of the right pointers and relevant principles of interpretation. The last part of the essay is a synthesis of an applied study case, described after the explanation of the methodology of the archaeological impact evaluation. In this study case we adopted the “quali-quantitative” evaluation techniques
