SEA USE MAP: GIS SUPPORTING MARINE AREA’S SUSTAINABLE DEVELOPMENT

The coastal zone is characterised by diversified physical and ecological conditions that allow the multiple use of natural resources. The overlap of very different uses generates conflict inducing habitat depletion and damage to natural systems. To face the problem of “conflict of use” of the coastal areas, we developed an integrated system as a working tool, the Sea Use Map (SUM), aimed to the characterization of the different values and uses of the marine resource, useful to explore further marine uses, such as suitable sites for marine renewable energy production, productive activities, etc. For this reason, the creation of an integrated GIS database, in which the information is conveyed in a geo-referenced system, is the necessary tool to support maritime spatial planning. The SUM of Italy is a key database, in which coastal uses are integrated with environmental data (seabed morphology, waves, currents, fauna, flora, etc.). Further integration between data and simulations of numerical models allows to define the most promising and ecologically acceptable areas for the introduction of new uses in view of the compatible development of the sea and marine resources. This paper presents a pilot application study in the coastal area between Capo Anzio and Tarquinia (Italy, Latium).
