The Province of Genoa is a Public Authority acting at an intermediate level between municipalities and Liguria Region, and incorporates the territory of 67 municipalities. The main role is promoting and coordinating the projects from the different municipalities, in two ways: through the construction of planning tools and through the promotion of local development projects. The Provincial Plan (PTC) is a general spatial planning tool approved in 2002 an actually under the decennial revision set by law. Its main goal is the coordination of development programs and projects at local level fitted in a broader perspective of Regional and European level. The Municipalities are the main interlocutors of the Plan directives, and represent the main actors for its implementation.

POLICYES: HIGH LEVEL POLICY STATEMENT Document in eight points signed by the President of Province on 15/12/2009 1. the General Territorial Plan of Province (PTC) of Genova is a quite fit tool for the assessment of the physical effects generated from climate changes in the Province area, and for integrating different thematic plans towards the establishment of effective adaptation measures; the PTC needs to be improved and integrated in its sections, updating the subjects that refer to the environmental sustainability and the development performance ability; 2. the Provincial planning tool must be updated through an Action Plan and integrated projects, that should face both methodological and coordination issues, both pilot projects delivery, involving local communities and Authorities, too; as a consequence of past delivered actions, the target area for demonstrative projects should be selected in the corridor Polcevera and Scrivia valleys; 3. by a morphological and environmental point of view, the Provincial land is featured as a chain of mountains, rich in woods, that lays in front of the Mediterranean sea, where the most dense urban area is enclosed in a narrow belt along the coast; even if this causes other core weaknesses and bad balances, the Provincial wide area, due to these true factors, looks quite less affected to climate changes than other national and European areas; therefore, among other adaptation measures, the maintenance of the local good environmental conditions should be stressed, with special care to the green areas system in urban zones and to ecologic corridors that may mitigate high density settlements, to the good quality of inner waters and to their relation with developed settlements, and to local micro-climates. 4. vulnerability to climate changes, risks and adaptation measures should be evaluated through a reliable, updated and flexible tool, able to answer to specific local issues; then, the GRaBS assessment tool should be used both for building programmes at Provincial level, both for delivering green and blue infrastructures projects in homogeneous physical contexts; 5. the Action Plan provision should be agreed by Municipalities and local communities; in a special way those involved in adaptation measures pilot projects, like the achievement of green and blue infrastructures prototypes; 6. local projects must be developed after gaining experiences already done in other similar contexts, acquiring outputs and assessing the results; 7. the Action Plan must state clearly what actual actions should be undertaken, how they should be delivered, what are the measurable results that are expected from; 8. according to the general principles of Provincial PTC, the adaptation actions to climate changes must be achieved through a cycle of launch, development, agreement, implementation, assessment and updating, that can allow to get the targets in harmony with the territorial dynamics.

GREEN AND BLUE INFRASTRUCTURES ALONG SCRIVIA/POLCEVERA STREAMS AND 2 DEMONSTRATIVE PROJECTS PL2 The starting point: What integrated approach for the river flooding mitigation and environmental protection? A survey field campaign was conducted in 12 different sites along Scrivia/Polcevera streams, editing detailed charts for each site. Main criteria for selection of the sites: potential connections with nearby urban areas uniform distribution along the rivers specific natural value On the basis of the analysis have been summed the most significant elements (natural and urban ones) for each selected area, recognizing negative and positive situations.

APPLICATION OF ASSESSMENT TOOL AT LOCAL LEVEL ADAPTO performing a web-gis visualization tool ADAPTO is structured on the basis of a set of environmental indicators, in order to analyze the current status of a territory, to assess its vulnerability and its aptitude to respond to changes ( resilience ). ADAPTO is now in a testing stage, but it will be improved and extended soon even to the evaluation procedure for the sustainability of plans and programmes (SEA - Strategic Environmental Assessment).
APPLICATION OF ASSESSMENT TOOL AT LOCAL LEVEL ADAPTO The toolkit allows to display the values of the eight selected indicators, the level of vulnerability associated with the relevant thresholds, and a parameter of final vulnerability. INDICATORS: Matrix, Interfering areas, Hydro-geological risk, Specialised uses, Fragmentation, Abandoned lands, Soil consumption, Drainage surface, Heterogeneity, Biological Capacity, Habitat standard vulnerability evaluation http://cartogis.provincia.genova.it/cartogis/grabs/adapto.htm
