Web GIS support for ICZM and Marine Spatial Planning

Offshore wind resource in Italy is not yet operating. RSE has been involved in studies about marine resource exploitation, by a technical, environmental and social assessment on offshore areas.

Since 2002 RSE has developed the Wind Atlas of Italy (onshore and offshore: 1 km grid resolution). RSE started on 2010 a modelling evaluation based on measured data of other marine energetic resources (es.: current, wave). The project is to develop an offshore energetic resource mapping tool in a WebGIS environment. The results presented in this work is relative to the coupling of the resource atlas with themes that can help the authorities to perform appropriate choice in marine source exploitation, through a marine spatial planning approach, considering also the Integrated Coastal Zone Management standards. The Italian autorizzative procedure for offshore resource is quite different that on land one, this procedure is not yet applied to renewable resource exploitation and there is a need for a strong technical support. The present tool completes the technical analysis performed by the Italian Offshore wind potential evaluation GIS, developed in RSE, too. The nowadays product is a webGIS of natural resource and marine and coastal human use; it shows information /layer in friendly and intuitive maps on these main themes: • Geographical indicators (national and administrative border, distance from the coast line -3, 5, 20 and 40 km on sea, 3 km on land; EEZ border) • Electric grid (on land grid and submarine cable) • Commercial and touristic vocation of the area (moorings berths, passenger and freight harbour trade, tourist accommodation) • Coastal land use (relevance for agriculture and valuable cultures) • Urban areas (residential, industrial, commercial, harbour, airport) • Protected areas (special areas of conservation, important bird areas, Ramsar areas) • Marine protected areas (Cetacean Sanctuary, marine special areas of conservation) • Other marine environmental and physical relevant element (sea beds, posidonia grassland) • Other marine anthropogenic use (touristic and commercial route, restricted use areas, offshore platforms, submarine cable, communication grid, and so on) The work is still in progress for inserting indicators that can complete an exhaustive picture for supporting decision in marine resource management. More marine environmental sensitivity indicators are needed, but their availability are far to be satisfying, because they are rarely extensively monitored. We consider the present state of development of the web GIS a precious tool for marine spatial planning.
