Practices for an Integrated Planning Between Urban Planning and Green Infrastructures for the Development of the Municipal Urban Plan (MUP) of Cagliari (Italy)

As underlined by the European Commission in Green Infrastructure (GI) - Enhancing Europe's Natural Capital (2013), in Europe, solutions based on green infrastructures are particularly used in urban areas to reduce pollution and health problems related to population growth, and to the settlement concentration of activities and residences. With this paper, the authors evaluate the link between the old sectoral model of infrastructure planning and a more functional one, based on the new green infrastructure paradigms used in different European cities. The main aim is to understand how these paradigms can improve the viability and the quality of life of the population in a coastal city with a particular frame on sustainability. To this end, starting from national and international examples, the authors outline typologies of integrated planning between urban planning and green infrastructures with particular reference to the relationship between historic city and waterfront in coastal cities. Subsequently, these typologies will be applied to the case study of Cagliari (Sardinia, Italy) as a tool to mitigate the fragmentation and unsustainable use of the soil with a particular frame in achieving the Sustainable Development Goals (SDGs). This allowed not only to study a model for the city of Cagliari for the regeneration of waterfront urban areas, but also for developing a system of green infrastructures capable of minimizing travel times within the city and of increasing the accessibility of slow mobility. This paper shows a first phase of research as part of the ongoing elaboration of the Municipal Urban Plan (MUP) of Cagliari.
