LAND UTILISATION IN THE AGER OF THE SASSARI CITY. THE COMPETITION WINE VS OLIVE BETWEEN THE 19TH AND THE 20TH CENTURY

Abstract

Le superfici a vigneto e olivo del comune di Sassari sono state indagate con analisi diacronica: Cessato (1860) e Nuovo Catasto Terreni (1920), Censimenti dell’Agricoltura Istat 1960- 2000 e carta di Uso del Suolo della regione Sardegna (2006). A metà del XIX secolo l’olivo, nell’Hortus, e la vite, nell’Ager, si estendevano su 3.884 e 2.986 ettari nell’ordine. I vigneti, colpiti dalla fillossera sul finire del XIX secolo, occupavano, nel 1920, solo 780 ettari contro i 5.074 dell’olivo. La diffusione dei portinnesti “americani” non era sufficiente per un completo recupero e i vigneti si estendevano, al 2000, su soli 191 ettari distribuiti in 353 aziende (Istat), mentre l’UDS individua al 2006 145 ettari ubicati in larga misura in quelle che erano le open lands di Saltus e Sylva.Vineyards and olive orchards were investigated in Sassari municipality (North Sardinia) by diachronic analysis of different source of data: cadastral (from 1860 to 1920), decal Agricultural Census (from 1970 to 2000) and Land Use Map (LUM) (2006/07). In 1860 Olives covered 3,884 hectares in the /Hortus/ system and Vines 2,986 hectares in the /Ager/ one. At the beginning of 20th century the vineyards decreased to 780 hectares because of the Grape phylloxera infection, while the olive stands increased to 5,074 hectares. Even the use of American resistant rootstocks did not allow the extension of the vineyards area that in 2000 was 191 hectares split into 350 farms. On the other hand, the LUM 2006 identified 145 hectares of it, most of them located in the old open lands of /Saltus/ and /Sylva/
