La Regione sostenibile. Forme giuridiche del regionalismo alla luce del principio di sostenibilità. Spunti comparativi dalle esperienze italiana, francese e spagnola = La Région durable. Formes juridiques du régionalisme au vu du principe de durabilité. Suggestions comparatives à partir des expériences italienne, française et espagnole

The thesis aims to deal with a classical theme (regional territorial organisation), in a comparative perspective (comparing the Italian Regione, the French Région and the Spanish Comunidad Autónoma) and adopting a dimension that is widely spread (sustainability). In this sense, the research, on the one hand, traces the reference framework of the whole work, introducing the basic concepts (Region; Regional State), not without having previously contextualised them in the perimeter in which it is (still) relevant to deal with them (the questions relating to territorialization and autonomy). Then, the thesis discusses certain characteristics ('static' and 'dynamic' variables of the 'regional state') which are described as emblematic, insofar as their function is both to provide a representative description of the 'regional state', abstractly considered, and to serve as a parameter of the comparative relationship between concrete regional experiences. On the other hand, the thesis analyses the subject of sustainability, attempting, firstly, to trace the origins of the concept and the processes of its "juridicisation" and "constitutionalisation". Secondly, it asks whether it is possible to propose further interpretations of sustainability that could prove useful for an analysis of institutional nature. This component of the work – a sort of "research within the research" – leads to the identification of a notion of institutional sustainability – and, in particular, of regional institutional sustainability – and of a series of potential indicators of sustainability. On this basis, the identified criterion is proposed as a key to interpret the experiences of 'regionalism', with a view not to give exhaustive and complete answers, but to provide useful elements for a fruitful reflection on the existence or not of conditions of permanent and future sustainability of the regional institution.
