DECISION SUPPORT CONCEPT TO DESIGN OF MARITIME SPATIAL PLANS RELATED TO DEVELOPMENT OF ANCHORING CAPACITIES – CASE STUDY CROATIA

Planning of nautical tourism development and especially planning of its supporting infrastructure (such as ports, marinas, anchorages) development are important topics when maritime spatial planning is conducted. Focus of research presented in this paper is in modelling of concept that will provide support to spatial planning specialists in design of maritime spatial plans (MSP) related to development of anchoring capacities for small vessels as a suitable framework for sustainable development of that nautical tourism branch. Even more precisely, research is focused in modelling of the decision support concept (DSC) to design of MPS meaning support to processes of identification, validation, comparison and selection of locations for construction of anchorages that will be included in MSP. It is complex and ill-defined problem because of several reasons such as involvement of multiple stakeholders having diverse interests, multi- disciplinarity, huge quantity of information and data (especially of spatial data), limited resources, numerous conflicting goals and criteria. Therefore proposed DSC is designed to enable inclusion of multiple stakeholders in all previously mentioned processes as well as to enable mitigation of the conflicts between stakeholders, making easier design and implementation of MSP. Furthermore, it supports design of MPS that define usage of maritime space in a way that enables maximization of positive social and techno-economic impacts of anchoring branch on local community while ensuring the highest possible protection of natural and cultural heritage. In order to cope with such complexity it is proposed a generic DSC to design of MSP for construction of anchorages based on Geographic Information Systems (GIS is used as a database and for provision of spatial analysis), multicriteria methods (PROMETHEE methods are used for comparison of locations, AHP method is used for determination of criteria weights), goal analysis (used for identification of significant goal, objectives and criteria in a form of a goal three) and logic of decision support systems (DSS). The concept is tested on design of MSP for the island of Solta in Croatia and it was proved as applicable, consistent, efficient and effective methodology for design of MSP.
