Abstract

In a changing climate, the agro-climatic characteristics of a wine region could significantly vary. Therefore, grapevine physiology, ripening time and grape quality at harvest, could be modified by climate change. The aim of this work is to investigate if there is a shift in climate suitability for the PDO “Terre dell’Alta Val d’Agri” wine growing area. Firstly, the climatic traits were assessed for the reference period 1985-2010. Afterwards, according to a “two periods” approach, the 2010-2018 time period, that represents the current condition, was evaluated. The Multicriteria Climatic Classification (MCC) (Tonietto and Carbonneau, 2004), through the use of Heliotermal, Cold night and Dryness indexes, was performed and the classification of the two periods was compared in order to highlight the differences in the suitability for wine production in the PDO area. The results show the trend towards a warmer and drier climate, with an increase in mean temperature (+1°C) and intensification of dryness (+21 mm of potential deficit). The study also shows that, according to MCC, no relevant viticultural regions in the world are highlighted with the same classification as Villa d’Agri for the 1985-2010 period. Otherwise in the recent period (2011-2018) the study area has similar climatic traits with an important wine-producing area, the Rio Negro wine region in Argentina. This agro-climatic shift reveals a great potential in the suitability of the PDO area for high-quality red wine production. In addition, the “two periods approach” could be applied to other grape growing regions in order to assess the effect of climate change on vineyard suitability for wine production.
