Le colline d’argilla dell’Appennino centrale: un territorio fragile = The clay hills of central Apennines: a fragile territory.

As confirmed by the earthquakes of recent years, the Central Apennines is a very fragile area, with a geological and seismic risk that has certainly contributed to the interruption of the agricultural economy and pastoralism that for centuries was his luck, and accelerated consequently the abandonment of the territory. The condition of progressive "return to nature", especially of the houses of land scattered throughout the territory, has here created a correspondence with the landscape that enhances its clayey nature and is one of its most identifying features. The use of raw earth for the construction of buildings, functional above all to the work of the fields, is so pervasive that it still marks the history and memory of the places, despite the progressive disappearance of most of them. The present contribution aims to bring new elements of knowledge on this landscape, focusing attention on its residual traces in order to verify the possibilities and opportunities for recovery and development.
