It aims at providing more detailed information concerning the state of implementation of each macro-regional strategy. The document is based inter alia on contributions from the key stakeholders of the strategies, EU institutions, Member States representatives, academia and experts. The differing structure between the individual chapters on each of the four macro-regional strategy is due to the different maturity of each strategy (they have been adopted at different time) hence the differing availability of data and deliverables.
Regarding EUSAIR, a development into the phase II (operating phase, ability of the MRS to manage joint structures, ability of stakeholders to establish joint structures, etc.) was recognised. Read more about it HERE.
