Rigenerare il patrimonio pubblico in chiave ecologica. Prospettive per il riuso dei beni militari nell’area metropolitana di Cagliari

The unsustainable anthropic pressure on the environment and landscape has led the discipline of urban planning, now in a stable manner, towards new ways of territorial government focused on the rational use of urban space and the preservation of the territorial capital. This debate includes the to pic of urban regeneration, which combines policies of socio-economic growth with the need to adopt strategies for the redevelopment, efficiency and re-use of existing settlements. The paper focuses on the public real estate, in particular the military heritage, characterized by a heterogeneous and large availability of areas and buildings in conditions of abandonment or underutilization, due to the pro gressive decrease of Defense needs. This asset is not very relevant within the urban planning and policies, while the potential reappropriation of these areas by communities and their integration into the urban network can represent an undisputed advan tage for urban ecosystem services. In this direction, the case study of Cagliari is represented by a vast military heritage, abandoned or awaiting for dispo sal, mainly located in strategic areas of landscape, identity and historical and cultural value, in close re lationship with the environmental components and the coastline. The proposed reflections focus on the role that the military heritage, disused from its ori ginal functions, could assume within a framework of plan strategies oriented to urban regeneration in relation to ecological networks, combining objecti ves of territorial rebalancing and reconnection of the urban fabric with the enhancement of historical, architectural and environmental heritage.
