Climate and Territorial Suitability for the Vineyards Developed Using GIS Techniques

Abstract

This study assessed the wine vocation of two grapevine cultivars (Maceratino and Sangiovese) in Macerata Province (Central Italy) for different periods: 1931–1960, 1961–1990 and 1991–2014. The maps of viti-cultural potential were edited using GIS software, on the basis of late frosts, optimum temperatures, water requirement and slope. Raster math allowed the summation of the parameters considered, also assessing climate change between periods, in relation to the crops. The aim of this research was to provide a valuable tool for more rational spatial planning.
