strategie per la sostenibilità dei paesaggi della lunga durata:architetture temporanee e autocostruite nello spazio rurale della Sardegna

Sardinia has an outstanding long-lasting landscape structure: here, rurality and archaeology create a palimpsest which is very strong in its characters but critically exposed to different forms of colonisation. The question is: “Can architecture to take care of these places with minimal actions, defining a sustainable intervention model which is compatible with them?” The contribution illustrates the provisional results of a multi-year research applied to the relationship between sustainable project and historical rural landscapes, under the coordination of DICAAR, framed in a broader regional strategy that aims to reduce the depopulation of the inland areas through the promotion of sustainable economic development and the enhancement of territorial specificities. It concerns rethinking the rural areas as “reservoirs of resistance” against urban concentration, allowing a more balanced relationship with the territory and exploring disciplinary borders consisting of much thought and few resources, whose paradigms become ecology, temporariness, reversibility and sustainability. A form of multifunctional colonisation, with a low territorial impact, capable of creating/recreating landscapes which are recognisable and suitable for new uses integrated and related to the conventional and productive ones; a landscape project that draws a regional-scale setting by creating coordinate systems of services that make these uses possible. The project and the construction of small concrete architectures for the activation of the rural space and archaeological landscapes, auto-constructed by students and local communities, becomes expression of a new form of “tactical landscaping”, a resistant thought that makes use of the principle of necessity and the paradigm of renunciation.
