Knowledge of ecosystem services (ES) and the benefits provided by offshore marine areas, including the welfare impacts from the establishment of marine protected areas (MPAs) is still limited. In the present study we evaluated benefits from ES, citizens' willingness-to-pay for potential changes in the provision of ES, and welfare losses to citizens due to restrictions on economic activities from establishing new offshore MPAs in Latvian waters. The scenarios for the economic valuation were based on analyzing the supply of ES from the protected marine habitats, showing changes in the ES supply in policy relevant scenarios of the MPA size. Our study evaluates a wide array of ES delivered by offshore protected habitats and reveals that citizens' willingness-to-pay for preserving habitats and ES supply exceeds their welfare losses from restrictions in economic activities. Our approach supports the prioritization of habitat types according to their contribution to ES supply and benefits for citizens. The analysis can be complemented with spatial data regarding the distribution of habitats, providing an opportunity to identify areas with the highest ES benefits to support marine protection and spatial planning.
Across Europe, countries are joining forces in order to implement European Commission initiatives as the Blue Growth Strategy and the Directive on Maritime Spatial Planning. Collaboration on how to perform stakeholder involvement as well as create cross-border solutions has become a key issue around the European sea basins and holistic spatial planning approaches similar to terrestrial planning practices are now being implemented in the marine environment. Among the sectors in marine governance is the maritime cultural heritage under water as well as in the coastal zone, where the example of the Baltic Sea Region illustrates how this sector has become an inherent part of the new Blue Growth discourse and the MSP-policy development across the region. In order to utilise this potential, support for collaboration and shared understandings within the maritime cultural heritage community of practise is needed. This research has focused on how to develop a spatially enabled digital and collaborative working environment to support the co-creation of new shared spatial planning concepts for maritime cultural heritage. The development of the platform itself has been carried out in a close cooperation with the actual users including cultural heritage experts, public authorities and research institutes in the Baltic Sea Region.
Collaborative spatial decision support tools can contribute with setups for including stakeholders into marine spatial planning (MSP) processes with the purpose of increasing trust in planning outcomes, facilitate knowledge co-creation and shared planning goals, and provide transparent, scientific, inclusive, and technical foundations for planning. A new collaborative spatial decision support setup based on the combination of functionalities from two spatial decision support tools called SEANERGY and Baltic Explorer was designed for and tested in a workshop in 2020 targeted local authorities, NGOs, and citizens in Denmark with an interest in MSP. While the setup needs further testing among a wider span of stakeholders to support a pluralistic approach, the findings illustrate promising potentials from ranking conflicts and synergies in collaborative settings to make marine activity interests spatially visible in MSP and gain an overview of opportunities for sea use multi-functionality in context-based, interactive, goal-oriented stakeholder processes. The use of a visual platform such as Baltic Explorer to systematically explore locations of marine uses was positively evaluated to facilitate the workshop conflict-synergy discussions. Challenges relate to how to deal with disagreements on conflict-synergy scores and the subjectivity of opinions, but the demonstrated flexible, quick, transparent way to test the sensitivity of spatial patterns to differences in input conflict-synergy scores is found to provide a promising setup for including stakeholder opinions through collaborative settings, a setup adjustable to supplementary large-scale, individual, more representative surveys as well.
This article deals with the implementation of ecosystem-based marine management in the Baltic Sea. It explores and documents in particular the preliminary lessons from environmental and fisheries management with reference to the Helsinki Commission Group for implementation of the ecosystem approach and the Baltic Sea Fisheries Forum, both examples of regionalization processes in order to implement ecosystem-based marine management. The Helsinki Commission Group for implementation of the ecosystem approach is a joint management body for the implementation of the Baltic Sea Action Plan and the European Union's Marine Strategy Framework Directive. The Baltic Sea Fisheries Forum is a new governing body to facilitate regional cooperation in fisheries management. The aim of the article is twofold: a) to describe and discuss two different pathways of regionalization in the Baltic Sea and b) to explore how these forms of regionalization could contribute to the implementation of governance structures needed to implement ecosystem-based marine management at the level of a regional sea – efficiently, legitimately and effectively. We conclude that a nested governance structure could be developed by building upon existing institutions while learning from new initiatives to organize stakeholder involvement.
The cybersecurity landscape is evolving, driven by a reinforcing feedback loop of increasingly sophisticated attacks and defences. Threat actors, long benefitting from the asymmetrical “attacker’s advantage” of focused targeting, have now matured their organizational structures to facilitate tactical information sharing, technique specialization, the establishment of markets for buying and selling exploit and vulnerability information, and providing training on how to circumvent detection and defence systems.
The report is organized as follows. The introduction will lay out the current state-of-play of eco-efficiency and the zeitgeist of the current situation on maritime that we find ourselves in, in 2020. The next section will provide some historical context looking back to 2010 and 2000 to trace the trajectory and developmental course on which we are. The core contribution of this report is the Maritime Operations Roadmap that can be found in Figure 1 on page 9. This illustration plots the expectations for technological capabilities and policy from 2020 to 2030.
The concept of 'seal-fishery conflict' is used when referring to the complex contradictions stemming from seals' impacts on fishing livelihoods, a pertinent social struggle between stakeholder groups of the Baltic Sea. Tensions are most remarkable between coastal fisheries and seal conservationists. As existing knowledge has been scattered and the conflict has become increasingly problematic, the RESOCO project compiled Nordic knowledge and best practices and built an interdisciplinary synthesis to set the stage for alternative solutions on how to effectively reconcile the seal-fishery conflict in the Baltic Sea. The report takes a pragmatic stand by turning the attention to approaches and instruments that have been suggested to be helpful or that have the potential to help mitigate the conflict. The report synthesizes knowledge and presents existing gaps and needs of further research.
The activities and emissions from leisure boats in the Baltic Sea have been modeled in a comprehensive approach for the first time, using a new simulation model leisure Boat Emissions and Activities siMulator (BEAM). The model utilizes survey data to characterize the national leisure boat fleets. Leisure boats have been categorized based on their size, use and engine specifications, and for these subcategories emission factors for NOx, PM2.5, CO, non-methane volatile organic compounds (NMVOCs), and releases of copper (Cu) and zinc (Zn) from antifouling paints have been estimated according to literature values. The modeling approach also considers the temporal and spatial distribution of leisure boat activities, which are applied to each simulated leisure boat separately. According to our results the CO and NMVOC emissions from leisure boats, as well as Cu and Zn released from antifouling paints, are significant when compared against the emissions originating from registered commercial shipping in the Baltic Sea. CO emissions equal 70 % of the registered shipping emissions and NMVOC emissions equal 160 % when compared against the modeled results in the Baltic Sea in 2014. Modeled NOx and PM2.5 from the leisure boats are less significant compared to the registered shipping emissions. The emissions from leisure boats are concentrated in the summer months of June, July and August and are released in the vicinity of inhabited coastal areas. Given the large emission estimates for leisure boats, this commonly overlooked source of emissions should be further investigated in greater detail.
Offshore energy hubs connect large amounts of offshore wind to a hub from where the generation can be transmitted to onshore, potentially linking to multiple surrounding countries. The benefits of such hubs, and the related meshed offshore grid to connect them, have been investigated in the North Sea. The system-wide impacts of offshore energy hubs in the Baltic Sea are less studied; however, the region is seeing increased interest in offshore wind development. This paper uses detailed offshore wind generation simulations and energy system optimisation to investigate the cost-effectiveness of offshore energy hubs in the Baltic Sea in different scenarios towards 2050. The results show that the largest deployment of offshore energy hubs occurs when the energy system is highly electrified. The strongest development of the offshore energy hubs occurs in the southern part of the Baltic Sea.
This article contributes to the accelerating development of methods for sustainability assessment (SA) to support maritime spatial planning (MSP), by proposing an ecosystem services based framework for SA. MSP is generally seen as an important approach to promote a more sustainable use of sea space. However, so far all sustainability concerns are not equally well represented in planning practice; in particular, social sustainability aspects such as social justice and sociocultural values related to human-nature connectedness receive less attention. We first explored concepts and principles related to sustainability assessment and social sustainability in the scientific literature. Based on this, we analyzed how far the present approaches to assessments in Baltic Sea EU Member States have been extended from environmental concerns to towards broader sustainability concerns so far. Using current best practice in two pioneering countries (UK and Sweden), we illustrated how social sustainability principles could match with applied social impact criteria, and further, how such criteria can inform an ecosystem services-based impact assessment framework. Based on existing frameworks, including the DPSIR (driving forces, pressures, state, impact, response) environmental assessment framework and the ecosystem service cascade, we propose a sustainability impact assessment framework for MSP (MSP-SA) integrating across sustainability dimensions and including assessment of distributional aspects of marine ecosystem service benefits. Finally, we discuss the applicability and further development of the framework in relation to present day sustainability assessment practice in MSP.
