The baseline entails mapping of the situation in the lighthouse area in 2021-22 with respect to the Mission objective 3, targets and activities. It covers maritime transport (with a focus on passenger ferry transport), maritime ports and facilities, offshore (and onshore) renewable energy facilities, offshore renewable energy storage facilities, multipurpose platforms, and aquaculture. The study also proposes indicators for measuring Mission progress in these areas during its implementation. Moreover, the study maps stakeholders and networks relevant to the implementation of the Mission objective, including a comprehensive mapping of past, ongoing and future key EU and national projects in the lighthouse area relevant to the Mission objective and activities. Furthermore, the study produces an analysis of the S3 Smart Specialisation Strategies and other regional strategies in the lighthouse analysing the synergies with the Mission objectives and activities and providing recommendations for their alignment with the new S4+ framework for sustainable and inclusive growth linking smart specialisation and Mission-oriented policy for sustainable development. In addition the study maps current governance mechanisms incl. regional, national and macroregional strategies and plans, but also National Recovery and Resilience Plans (RRPs) aiming to mitigate the economic and social impact of the Covid-19 pandemic, and their alignment with Mission objectives. The study furthermore investigates and maps citizen engagement and literacy activities. Moreover, for each sea basin, a general data-base and descriptive overview is provided in terms of geography, demographics and socioeconomic situation, information on governance and administration, and an analysis of regional disparities has been performed, related to the differences in the socioeconomic performance of the regions, as well as the differences in the performance and connectedness of the research and innovation (R&I) ecosystems to European counterparts. The methodology comprises a multitude of methods such as desk research, data analyses using various open databases, case studies, surveys and stakeholder interviews. The study offers recommendations for further implementation of the Mission in the areas covered by the study. The results will feed into activities to implement the Mission, such as the Mission Implementation Platform and the Coordination and Support Actions (CSAs) in the lighthouse.
