The diversity and intensity of human activities in the North Sea region (NSR) and other maritime regions are increasing. This necessitates transboundary coordination at the sea basin level, which is required but yet insufficiently established. Through European co-funded projects, national policymakers, stakeholders, and scientists in MSP are enabled to develop transboundary coordination (TBC) mechanisms. TBC requires, alongside other factors, a form of social and policy learning between these actors in different countries. The NorthSEE project (2016–2022) was an example of such an EU-co-funded project and was aimed at enhancing coherence in MSP processes and plans across the NSR. This article examines the project's key learning outcomes, the role of the MSP Challenge Simulation Platform in supporting these outcomes, and factors that enabled or constrained learning within the project. Data was collected during the project via document analysis, questionnaires from participatory stakeholder workshops, interviews with sixteen project participants and ten workshop participants, and observations. The study highlights that project participants have gained more insight into each other's planning systems, are able to contact each other more easily, and have initiated several follow-up initiatives. Furthermore, it shows that interactive and participatory tools, such as the MSP Challenge Simulation Platform, can contribute to individual and social learning by providing participants with instant feedback on their decisions. These learning outcomes have been influenced by various enabling and constraining conditions, including time, resources, and the differing levels of expertise and knowledge among project partners and participants. Assessing the broader societal impact remains a challenge and warrants further attention.

The EU Maritime Spatial Planning Directive (MSPD) requires the member states (MS) to pursue Blue Growth while ensuring good environmental status (GES) of sea areas. An ecosystem-based approach (EBA) should be used for the integration of the aims. However, the MSPD does not specify how the MS should arrange their MSP governance, which has led to a variety of governance arrangements and solutions in addressing the aims. We analysed the implementation of the MSPD in Finland, to identify conditions that may enable or constrain the integration of Blue Growth and GES in the framework of EBA. MSP in Finland is an expert-driven regionalized approach with a legally non-binding status. The results suggest that this MSP framework supports the implementation of EBA in MSP. Yet, unpredictability induced by the non-binding status of MSP, ambiguity of the aims of MSP and of the concept of EBA, and the need to pursue economic viability in the coastal municipalities may threaten the consistency of MSP in both spatial and temporal terms. Developing MSP towards a future-oriented adaptive and collaborative approach striving for social learning could improve the legitimacy of MSP and its capacity to combine Blue Growth and GES. The analysis indicates, that in the delivery of successful MSP adhering to the principles of EBA should permeate all levels of governance. The study turns attention to the legal status of MSP as a binding or non-binding planning instrument and the role the legal status plays in facilitating or constraining predictability and adaptability required in MSP.

Managed realignment is the landward relocation of flood infrastructure to re-establish tidal exchange on formerly reclaimed land. Managed realignment can be seen as a nature-based flood defence system that combines flood protection by the realigned dike (artificial) and restored saltmarshes (nature-based). So far, research on coastal managed realignment is primarily directed to saltmarsh restoration on formerly reclaimed land. This study focuses on the realigned dikes. The aim of this research is to characterize realigned dikes and to indicate the characteristics that offer opportunities for nature-based flood protection. We categorized 90 European coastal managed realignment projects into two realigned dike groups: (1) Newly built landward dikes and (2) Existing landward dikes of former multiple dike systems. The second group has two subcategories: (2a) Former hinterland dikes and (2b) Realignments within summer polders. For each group we present the realigned dike characteristics of a representative case study. We consider that the use of existing landward dikes or local construction material make realignment more sustainable. From a nature-based flood protection perspective, the presence of an artificial dike is ambiguous. Our results show that targeted and expected saltmarsh restoration at managed realignment does not necessarily result in a greener realigned dike design that suits for combined flood protection with restored saltmarshes. We recommend coastal managers to explicitly take combined flood protection into account in the realigned dike design and steer the topography of the realignment site to facilitate nature-based flood protection and promote surface elevation increase seaward of the realigned dike in response to sea level rise. This makes managed realignment a nature-based flood defence zone for now and for the future.

Like most ocean regions today, the European and contiguous seas experience cumulative impacts from local human activities and global pressures. They are largely in poor environmental condition with deteriorating trends. Despite several success stories, European policies for marine conservation fall short of being effective. Acknowledging the challenges for marine conservation, a 4-year multi-national network, MarCons, supported collaborative marine conservation efforts to bridge the gap between science, management and policy, aiming to contribute in reversing present negative trends. By consolidating a large network of more than 100 scientists from 26 countries, and conducting a series of workshops over 4 years (2016–2020), MarCons analyzed challenges, opportunities and obstacles for advancing marine conservation in the European and contiguous seas. Here, we synthesize the major issues that emerged from this analysis and make 12 key recommendations for policy makers, marine managers, and researchers. To increase the effectiveness of marine conservation planning, we recommend (1) designing coherent networks of marine protected areas (MPAs) in the framework of marine spatial planning (MSP) and applying systematic conservation planning principles, including re-evaluation of existing management zones, (2) designing MPA networks within a broader transboundary planning framework, and (3) implementing integrated land-freshwater-sea approaches. To address inadequate or poorly informed management, we recommend (4) developing and implementing adaptive management plans in all sites of the Natura 2000 European conservation network and revising the Natura 2000 framework, (5) embedding and implementing cumulative effects assessments into a risk management process and making them operational, and (6) promoting actions to reach ‘good environmental status’ in all European waters. To account for global change in conservation planning and management, we further recommend (7) developing conservation strategies to address the impacts of global change, for example identifying climate-change refugia as high priority conservation areas, and (8) incorporating biological invasions in conservation plans and prioritizing management actions to control invasive species. Finally, to improve current practices that may compromise the effectiveness of conservation actions, we recommend (9) reinforcing the collection of high-quality open-access data, (10) improving mechanisms for public participation in MPA planning and management, (11) prioritizing conservation goals in full collaboration with stakeholders, and (12) addressing gender inequality in marine sciences and conservation.

Snelle technologische ontwikkelingen bieden kansen voor de maritieme sector. Zij maken de scheepvaart efficiënter, veiliger en schoner. De techniek heeft regelgeving en professionals nodig die ook klaar zijn voor de toekomst. Het lectoraat Maritime Law voert praktijkgericht onderzoek uit op de scheidslijn van recht en (maritieme) techniek samen met studenten, docenten, het bedrijfsleven en kennisinstellingen.
