摘要：The article addresses the contemporary debate on urban and environmental regeneration, investigating the need to establish new criteria to implement the defence of coastal ecosystems by climate problems. The research looks at coastal vulnerabilities, starting with the environmental fragility of flooding, as an opportunity to regenerate waterfront ecosystems. The research aim concerns the analysis of US advanced regeneration practices to learn and transfer the principles derived from them to the European context. This transferability takes place through the construction of regeneration criteria for the coastal ecosystems rebalancing. The regeneration criteria are resulted from an ecosystem reading of the winning projects of the <i>Rebuild by Design</i> competition. These practices represent in the scientific literature an exceptional example of a holistic response to the problem of post-disaster intervention. These cases offer an integrated response in terms of processes, investments, the duration of the design and realization. In addition, these cases simultaneously address multiple vulnerabilities, making it possible to extrapolate from their analysis specific directions to replicate in contexts where even just one of the critical issues exist. The methodological analyses exploit the focus emerged from the scientific literature on environmental vulnerabilities, technological innovation, and stakeholder involvement. The results are regeneration criteria able to verify the appropriateness of ecosystem anti-flooding strategies. Comparing the results with the most recent US and the EU strategic documents, the regeneration criteria demonstrate their relevance and coherence with the international priorities as well as their potential transferability to the European context.
