With expanding human uses at sea, the objective of maritime spatial planning (MSP) to promote sustainable coexistence between marine uses becomes an increasingly challenging task. In order to assess coexistence options, both use-use interactions and use-environment interactions are important to explore. Tools for doing cumulative impact assessments (CIA) on the environment provide a means for spatially exploring environmental impacts. Finding inspiration in such ecosystem-based spatial use-environment approaches while drawing on pairwise marine use compatibility knowledge from existing literature, a spatial approach to model potential synergies and conflicts between marine uses through an expert-based scoring system is presented and implemented in SEANERGY, an ArcMap-based opensource toolbox. A test based on Baltic Sea GIS data demonstrates how SEANERGY supplements CIA analyzes with knowledge about potential use-use synergies, potential use-use conflicts, and their spatial extents, useful for optimizing the use of marine space in MSP without putting too much cumulative pressure on the environment.
The SEAwise project works to deliver a fully operational tool that will allow fishermen, managers, and policy makers to easily apply Ecosystem Based Fisheries Management (EBFM) in their own fisheries. One of the key uncertainties in fisheries science and management can be linked to (our understanding of) fishermen's behaviour. In this report we describe the project efforts to better understand fisher behavior by assessing literature, interviews and data to advance towards a better representation of fisher behavior in our modelling. A better understanding of fisher behavior is especially needed in the context of change affecting Europe's marine ecosystems. Change is both related to the natural part of the ecosystem (ie climate change) as to the social side of the ecosystem (ie building of wind parks).
To that aim we present nine different case studies in Europe as examples of how fisher behavior has been studied and which factors are (or can be) relevant for a better understanding of fisher behaviour. Each case study ends with a table summarizing the factors influencing behaviour, the categories within that factor and the (potential) application in modeling as well as the implications for management. The table below summarizes the factors found / used in the case studies and the elements (social, cultural, ecological, economic and institutional) to which they relate. A variety of social factors were identified that are promising for use in modelling. A key conclusion is that social data are often context dependent and cannot be copy pasted from one situation to the other and in some cases, additional data needs to be collected. The cases also demonstrate that mixed methods approaches and interdisciplinary approaches are key to get in-depth understanding of fisher behavior in fisheries science.
This report discusses the concept of governance, how to understand 'effective' governance, and a research plan for further studies of the effectiveness of and potential for improving governance at the regional and sub-regional level in the SEAwise regions (Baltic Sea, North Sea, Western Waters, and the Mediterranean Sea). The theoretical insights from the first two main parts inform and are merged into the research plan, forming the last part of the report. The work is based on the recognition that fisheries management in Europe is still struggling to deliver on its objectives relating to ecology, economy, and social considerations although improvements have been made over the last decades. On top of this, marine biodiversity and ecosystem integrity can be identified as pressing challenges, while climate change presents renewed uncertainties and risks.
Improved governance, appropriately designed for Ecosystem Based Fisheries Management (EBFM), is key to improving the system performance towards the societal objectives. Lack of appropriate measures towards cooperation between the EU, national, and regional levels has led to uncoordinated decision-making processes and prevented coherent management through the implementation and adoption of EU legislation, leading to lower than desired performance both of fisheries and environmental policies. Referring specifically to the involvement of stakeholders, the European Commission stresses the importance of transparency, cooperation, outreach, information, and inclusiveness in developing and implementing measures to ensure that all stakeholders, not least fishermen, have a say in the management process, and that their needs and concerns are considered (European Commission, 2023a). Improvement of what can broadly be defined as 'governance' is, thus, among the pathways that the European Commission has identified for improvements in the area.

The selection of alternative energy sources for shipping can effectively mitigate the problems of high energy consumption and severe environmental problems caused by shipping. However, it is usually difficult for decision makers to select the most sustainable alternative energy source for shipping among multiple alternatives due to the complexity of considering different aspects of performances and the lack of information. This study developed a novel multi-criteria decision-making method that combines Dempster-Shafer theory and a trapezoidal fuzzy analytic hierarchy process for alternative energy source selection under incomplete information conditions. According to the developed method, nuclear power has been recognized as the most sustainable alternative energy source for shipping, followed by liquefied natural gas (LNG) and wind power, and sensitivity analysis reveals that the weights of the criteria have significant on the sustainability sequence of the three alternative energy sources for shipping. The developed method can be popularized for selecting the most sustainable alternative energy source despite incomplete information.
The aim of this paper is to provide the foundations for the development of a spatial decision-support toolset that combines cumulative impacts and ecosystem service supply assessments to support what-if scenario analysis in a maritime spatial planning context. Specifically, a conceptual framework for a toolset has been designed in order to introduce a new approach for place-based assessments of change in relative ecosystem service supply in multiple services at a time due to changes in cumulative impacts. Central to the toolset are two pre-existing approaches for relative ecosystem service supply and cumulative impact assessments and tools that facilitate them. The tools take advantage of available data from various sources, including geodata and expert knowledge, and have already been proven to support maritime spatial planning in a real-world context. To test the new approach and demonstrate the outputs, an ecosystem service supply assessment was done manually using the two currently separate tools. The results of the test case ecosystem service supply assessment for the Gulf of Riga in the Baltic Sea are also presented in this paper and illustrate the assessment steps and data needs. Although presently the focus of the illustrative assessment is the Gulf of Riga, the toolset will be able to accommodate analysis of cumulative impacts and service supply of any location, leaving the scope of the assessment to be determined by the objectives of the assessment as well as data availability (i.e., geospatial data availability and extent of expert knowledge).
The “Initial IMO Strategy” was adopted in the 72nd session of the Marine Environment Protection Committee (MEPC 72) of the International Maritime Organization (IMO) in April 2018. It has set, among other things, ambitious targets to reduce greenhouse gas (GHG) emissions from ships, and purports to express a strong political will to phase them out as soon as possible. The most ambitious of these targets is to reduce GHG emissions by 2050 at least 50% vis-à-vis 2008 levels, and there is also an intermediate target to reduce CO2 emissions per transport work by 2030 at least 40%, again vis-à-vis 2008 levels. More than three years since the adoption of the Initial IMO Strategy, this chapter takes stock at the status of shipping decarbonisation and attempts to assess prospects for the future. Obstacles towards achieving the IMO targets are identified and discussed.
The profile of small-scale fisheries has been raised through a dedicated target within the United Nations Sustainable Development Goals (SDG14b) that calls for the provision of 'access of small-scale artisanal fishermen to marine resources and markets'. By focusing on access to fisheries resources in the context of the European Union, in this article we demonstrate that the potential for small-scale fishing sectors to benefit from fishing opportunities remains low due to different mechanisms at play including legislative gaps in the Common Fisheries Policy, and long-existing local structures somewhat favoring the status quo of distributive injustice. Consequently, those without access to capital and authority are faced by marginalizing allocation systems, impacting the overall resilience of fishing communities. Achieving SDG14b requires an overhaul in the promulgation of policies emanating from the present nested governance systems.
For the EU's Common Fisheries Policy, solving the discard problem is a central issue. Through a study of the institutional set-up and initiatives to solve the discard problem in Denmark, the Faroe Islands, Iceland and Norway, the article identifies the discard problem as related to natural and other material conditions as well as cultural conditions. Therefore, solving the discard problem requires not only technical and regulatory instruments, but also arenas and structures that allow and support cultural change processes.
Marine Spatial Planning (MSP) requires the analysis of the spatial distribution of marine uses and environmental conditions. Such analyzes can be carried out with GIS, but standard GIS programs do not feature a toolbox that combines the most needed functionalities for such analyses. The SPACEA toolbox presented here was created to bundle and adapt existing functionalities in one toolbox. SPACEA consists of several script tools that have been designed to be user-friendly and applicable to different analyzes for MSP. This includes the processing of different input layers with regard to marine uses and environmental conditions. The main functionalities of SPACEA are exemplified in a fictional case study in the Baltic Sea, where the tools are applied to find potentially suitable areas for mussel farming. The tools feature a user-friendly interface and more experienced users may also use the provided sample codes to run it from the python window or as a stand-alone script. As such, the tools can be applied by users with different levels of GIS knowledge and experience.
