The Blue Frontiers report is a useful tool for those who intervene in the management and transformation of the fi ve waterfront examined by the WaRe project but, more generally, can be taken as a model for comparative analysis of processes of revitalization in complex pieces of territory. As shown in the text and in the articulated comparison tables, the process of redefi nition waterfront areas can be understood as a laboratory for the analysis of the complexity in the relationship between built and natural environment. An environment rich in economic, social, environmental potentials, but vulnerable on many fronts. The case studies, each one diff erent in terms of dimensional, economic, historical, administrative aspects, share the fact of being regeneration processes in progress. This makes this work a valuable observation of alive processes, caughts in their development, including expected results but also unforeseen problems and yet untapped potential.
