Evaluation of terroir suitability for vine cultivation in new areas using geographic multi-criteria decision support
Based on historical vine cultivation, the recent development of wine production in Drama wine region (Greece) has led to vine cultivation expansion of white and red varieties. The current cultivation of 500 ha of vineyards is expected to increase in the coming years. Natural terroir units (NTU) have been designed recently to support the production of high quality wines in the region . The aim of this work is to evaluate the relevancy of the proposed NTUs regarding their suitability to produce wines of specific sensorial identity, and to provide guidelines for correct site selection for the expanding wine industry of the region. The FAO Framework for Land Suitability Analysis was adapted to cover the main categories of input data: soil, climate, topography and other environmental properties . The weights of each input data category have been developed with Analytical Hierarchical Process (AHP) based on interviews with the viticulturalists of the main wine producers. The geographic analysis was performed using the Agricultural Land Use Evaluation System (ALUES), which is based on the open-source statistical software R. The results reveal that the majority of the agricultural area is marginally to adequately suitable for the main white vine varieties currently cultivated, namely cv. Sauvignon blanc, with the exception of the cooler areas. On the contrary, red varieties (notably cv Cabernet Sauvignon) were found to be more suitable to occupy the central part of the wine producing area. Nevertheless, it is possible to allocate white varieties to a wider range of sites with the adaptation of viticultural management.
