“…Developing a spatial understanding of where conditions are most suitable for the three most commercially important species of mussels, Crassostrea gigas, Mytilus galloprovincialis, and Ostrea edulis, is required before priority areas for aquaculture expansion can be identified. To do so, we followed the methods outlined in existing literature to derive aquaculture suitability scores (Valentini et al 2016;Davaasuren et al 2010;Andersen et al 2013), which we then vetted with national aquaculture experts. This process defines eleven important indicators related to three criteria: environmental quality, optimal mussel growth conditions and socio-economic considerations (Appendix S.3).…”

Aquaculture is the fastest growing food production industry in the world yet research and guidance demonstrating strategic multi-objective zoning for sector expansion is scarce. Quantifying and mitigating conflicts and impact on sensitive coastal environments through jointly-optimized objectives for aquaculture and biodiversity simultaneously has not been tested yet.We here develop and evaluate six alternative planning scenarios for one of the European Union's highest priority mussel aquaculture areas, the Emilia-Romagna Region in Italy. We i) develop an aquaculture profitability surface as a function of the distance from main ports, and in parallel build a fine-scale aquaculture suitability distribution surface for important commercial species using multi-criteria analysis;ii) prioritize protected areas for biodiversity while testing how different considerations of human impacts influence priorities; iii) simultaneously plan for aquaculture and biodiversity while minimizing impacts on other maritime activities. We compare results from different scenarios according to how well they capture suitable aquaculture habitats and minimize impacts. We introduce a new evaluation method for scenario comparison in spatial optimization using a nearest-neighbour analysis for spatial pattern similarities. Lastly, we test the "value of information" provided by our investment in developing the fine-scale suitability surface to improve efficiencies. We find that an integrated multi-objective zoning approach, which simultaneously optimizes for biodiversity and aquaculture, supports more efficient planning than traditional sector specific growth strategies. We also discovered that the fine-scale suitability model delivered an 8% more efficient solution than the simple distance function, highlighting the role of proxy surfaces and diminished returns from investing in comprehensive habitat suitability analysis in regions without much variation in key parameters.We offer evidence of improved efficiency and practical guidance for integrated planning in Blue Growth agendas. Our analysis can be applied in any context where multiple objectives occur for aquaculture sector growth and biodiversity conservation.

“…Furthermore, decision-making processes have been applied in MSP in studies dealing with the protection of environment, ecology, biodiversity, coastal, and seabed habitat features [36][37][38][39][40][41][42][43]; marine traffic [44][45][46][47][48][49][50][51][52][53]; planning strategy of anchorage [54]; and site identification and selection [55][56][57][58]. Most of the studies that have had applied decision making for different activities in MSP deal with ecological issues and regulation of traffic within maritime industrial ports, but none of them made a development of the spatial plans related to the construction and economical aspects of anchorages.…”

The focus of this paper is to define anchorage management model for concession planning purposes to provide quality support to experts in spatial planning when developing maritime spatial plans. The research aim is to develop an anchorage management model that includes decision and concession support concept. Decision support concept is defined in order to support the processes of identifying potential anchorage locations, their evaluation and comparison, and finally, the priority ranking and selection of locations for their construction. The final step is modelling the concession support concept that includes financial analysis to concession parameters definition. The problem of decision making and concession of the anchorage location selection is complex and ill-structured because of the unsystematic and ad-hoc decisions by all included stakeholders. Additionally, the involvement of several stakeholders’ groups with different preferences and background knowledge, a large amount of conflicting and seemingly incomparable information and data, and numerous conflicting goals and criteria impact final decisions. The proposed concepts overcome the above obstacles in order to enable the construction of anchorages in a way of optimal use of maritime space. The model is tested on the island of Brač, Croatia. The methods used to solve the task are SWARA (The Stepwise Weight Assessment Ratio Analysis) for defining the criteria weights and ELECTRE (Elimination and Choice Expressing Reality) for ranking anchorage locations.

“…This can be coped with the fact that most countries have just started to apply MSP. The application of DS in MSP has been found in papers dealing with the protection of environment, ecology, biodiversity, coastal, and seabed habitat features [19][20][21][22][23][24][25][26], marine traffic [27][28][29][30][31][32][33][34][35][36], anchorage planning strategy [37], and site identification (selection) [38][39][40]. It can be concluded that most of the papers, in which DSS is used in the planning of various activities in MSP, are based on ecological issues, and on the issue of regulating traffic within maritime industrial ports, but not with the development of spatial plans, and especially not with plans related to the construction of anchorages as a civil engineering problem.…”

The planning of nautical tourism development and especially, the planning of its supporting infrastructure development, is important topic of the maritime spatial planning. The focus of research is the integration of multicriteria analysis and stakeholders within concept modeling that will provide support to the spatial planning specialists in the design of plans related to the development of anchorage capacities for small vessels. It examines economic, environmental, ecological, social, and civil engineering concerns related to the use of coastal water. It is a complex and ill-defined civil engineering problem because of multiple stakeholders with diverse interests, numerous conflicting goals and criteria, huge quantities of information and data, limited resources, etc. The research is concentrated on an integral approach to sustainable decision-making within maritime spatial planning by the modeling decision support concept to the processes of identification, validation, comparison, and the selection of locations for anchorage construction, based on multicriteria methods, goal analysis, and the logic of the decision support system. The concept is tested on the island of Šolta, Croatia, and has been proven as being an applicable, consistent, efficient, and effective methodology for the planning of the anchorage locations.
