This deliverable is included in task 3.4 of WP3 and focuses on identifying new tailored actions to enhance the contribution of regional and local levels to Maritime Spatial Planning initiatives. Through a comprehensive analysis of planning instruments, knowledge base and stakeholder engagement across eight case study regions, this task integrates previous findings to address emerging opportunities, challenges, gaps, and needs. The objective is to develop tailored actions that optimize MSP processes and align them with regional, national, and European policies. Finally, by prioritising actions that address multiple needs simultaneously, the last sectionprovides avenues to enhance the feasibility and efficiency of MSP implementation, through resource optimisation and improved objective integration.
