The Blue Bioeconomy defined as ‘the production and conversion of renewable marine biological resources into value added products, such as food, feed, bio-based products and bioenergy’ entails a large set of opportunities for European coastal communities. Innovative business models based on circularity; short-chains, digital solutions and ecosystem contributions offer the chance to stabilize and create new enterprises and jobs also for the lower-educated; while transforming remote, rural areas also into interesting, revitalized, climate-friendly places to live. However, blue bioeconomy actors struggle with challenges related to technology, lack of knowledge & skills or regulatory barriers. BlueBioClusters brings together 12 support organizations from across Europe, all of them highly engaged in their 9 regions in assisting start-ups, companies and policy makers to make best use of innovations. They have joined forces to improve, develop and implement new support tools and methods based on systematic collection, benchmarking and joint knowledge creation on *blue biobased value chains, practice cases and incentives, WP2; *ecosystem service valorization, WP3; *technology needs, identification and transfer of solutions, WP4; *start-ups/SMEs; experts and support mechanisms (coaching; co-creation), WP5; as well as *‘Communities of Practices’, to foster long-term stakeholder cooperation within and across the regions; WP6. While we expect to create long-lasting impact already within the project lifetime by engaging with hundreds of actors within our regions to stimulate collaboration and actions for change; activities are designed to be continued post-project, being also open for other Blue Regions, clusters and individual companies to join. To that end, the inter-active BlueBioCluster platform will not only serve as a repository of the projects’ outputs in terms of stakeholders and services, but is set up in such way, that it will be continuously updated and maintained by and with its users also post-project.

The goal of the COASTAL project is to formulate and evaluate business solutions and policy recommendations aimed at improving the coastal-rural synergy to foster rural and coastal development while preserving the environment. Rural development in the EU is increasingly affected by changing market developments, decreasing population densities, urban sprawl, lack of employment, desertification and other environmental, economic and social pressures. On the other hand, coastal areas provide interesting business opportunities but are also influenced by economic activities in the hinterland. Multi-Actor Approaches will be combined with System Dynamics to analyse the environmental, economic, and social interactions of rural and coastal areas in a holistic manner. The underlying feedback structures governing the dynamics, vulnerabilities, limitations, and business opportunities of the land-sea system will be identified and analysed, taking into consideration the regulatory frameworks, stakeholder priorities and social-economic conditions at the local, regional and macro-regional scale levels. Multi-Actor Labs using qualitative and quantitative tools will be set up to support the co-creation exchanges between scientific experts, stakeholders, business entrepreneurs, sector- and administrative representatives. The project will be structured around six closely interacting work packages with six complementary case studies in Sweden, Belgium, France, Spain, Greece and Romania.
