In southern Italy many cities are characterized by a lack of public urban greenspaces. Non-urbanized areas in these cities are suffering from surrounding urbanization pressures. These areas still provide important ecosystem services even if they are limited in size, highly fragmented and often neglected by local planning. New planning strategies are needed in order to protect and enhance the provision of ecosystem services delivered by existing Non-Urbanized areas, but municipalities usually have limited funds for acquiring public green areas via land expropriations. At the same time, requests for new urban development are still considerable. Consequently, it is not realistic to propose strategies for green areas that do not include new developments. The paper illustrates a strategy for a Green Oriented Urban Development (GOUD) that has been applied for the Master Plan of Catania, a medium sized city in Sicily (southern Italy). The strategy includes a limited amount of developments as well as new greenspaces in selected areas (Resource Zones), through the transfer of property and development rights between the municipality and developers. The strategy will allow to enhance the provision of ecosystem services, especially cultural services (thanks to a dramatic increase of accessibility to new greenspaces), regulating services (through climate regulation by new green land covers) and provisioning services such as urban agricultural products. Results show that it is possible to improve urban ecosystem services creating a more liveable and healthy urban environment at reduced cost for the municipal administrations.
