Urban green governance and mechanisms of generation of ecosystem services: Milan's green governance models

This paper studies the governance of the green spaces in the metropolitan area of Milan, aiming to understand the political mechanisms that underpin the generation of ecosystem services in the urban context. Based on semi-structured interviews to relevant policymakers and stakeholders and on the study of planning documents and greening policies, the research identifies the main actors who are involved in green planning and management in the city and in the metropolitan area. By analysing their green management and planning roles, economic resources and greening visions and priorities, the study depicts five coexisting green governance models. In particular, the research highlights the decreasing influence of public institutions in green planning and management and the rising relevance of private-public collaborations. These dynamics of green governance may affect the generation and the distribution of ecosystem services. On the one hand, greening in private-led regeneration processes tend toward recreational and final ecosystem services, aiming to raise land values. On the other hand, the civic projects of afforestation have evolved in territorial initiatives that go beyond the mere objective of implementing new green spaces, looking at broader planning themes - i.e. soft mobility and social welfare - demanding a stronger metropolitan coordination.
