Dinamiche di spopolamento in Sardegna. Problematiche e potenzialità di casi studio a confronto

This study shows the first results of a wider interdisciplinary research, carried out by the school of Architecture of Cagliari, concerning the extensive phenomenon of abandoned villages and processes of depopulation. Starting from a taxonomic approach, the heterogeneity and complexity of the aspects involved in the activation, increase and interruption of these ongoing processes has been highlighted. Then, the study proposes a classification of the built settlements according to their typology and state of conservation, and to the causes and level of abandonment. Among the investigated case studies, some of them ‒ the ruins of Gairo Vecchia, the lost village of Palmas Suergiu, the industrial village of Ingurtosu and the burgh of Monteleone Rocca Doria ‒ can be considered significant and representative of the Sardinian processes. Constants and variables rise from the comparison among cases. In particular, considering the most interesting factors, the relationship between old and new centres, built to host homeless communities, can be underlined, and the role of the protection policies in the conservation processes of architectural structures, which are the remains of the lost villages.
