LA SARDEGNA INTERNA TRA TRANSUMANZA E ZONA BLU. DINAMICHE SOCIO-SPAZIALI, STILE DI VITA RURALE E ALIMENTAZIONE DI UN’AREA GEOGRAFICA DI ECCEZIONALE LONGEVITÀ: L’OGLIASTRA

Sardinia between transhumance and the Blue Zone. Socio-spatial dynamics, rural life- style and diet of a geographical area of exceptional longevity: Ogliastra. – The rural dimension of Sardinia is strongly represented by the historical and social role assumed by agricultural activities on the island, which have always been characterised by transhumance phenomena (in Sardinia Tramuda) that, at different scales from the rest of Italy, have characterised some Sardinian rural territories (Ortu, 1988; Lai, 1998). Ogliastra has long been one of the lands of transhumance in Sardinia (Schiavone, Schiavone, 2014), and is marked by a high number of long-lived individuals (Blue Zone), for which, the rural environment, lifestyle and local interrelation- ships and genetics have influenced the health status in this area (Pes and Poulain, 2014). The work aims to investigate the socio-spatial dimension of food production linked to the rural (transhumant) culture of Ogliastra, trying to understand the configurations of territoriality (Turco, 2010) and how this socio-spatial, rural and food model may have influenced the particular longevity of the area. The Blue Zone diet, in fact, typical of transhumant territories, can become a catalyst for the sustainable devel- opment not only of Sardinia but also of many small Mediterranean rural areas and, furthermore, can facilitate the re-appropriation by the younger generations of their ancient identity heritage.
