Development of a webGIS Application to Assess Conflicting Activities in the Framework of Marine Spatial Planning

Marine spatial planning (MSP) has been established as the appropriate policy framework to study and resolve conflicts that arise among various activities. A pre-requisite for the successful implementation of MSP is the availability of efficient tools to support decision-makers and enhance stakeholders’ engagement. In this paper, a webGIS application is proposed that is able to assess the intensity of conflicts among marine activities; the area of the Cyclades in the Aegean Sea was used as a case study. The webGIS application allows the visualization of existing activities, the delineation of conflicting activities, the detection of areas where multiple conflicts co-exist, and the delineation of areas of conflicts based on specific criteria. The webGIS application is available via a user-friendly interface as well as allowing interaction with users by providing them the opportunity to comment on the results and/or exchange ideas with other users of various groups; therefore, the participatory process, a creative stage in MSP, is further supported. The usefulness of such tools in coastal and marine planning and the decision-making process are further discussed.
