The Winemaking Sector under Changing Climates
Viticulture and wine production are a very important sector in many areas of the world, including southern Europe and the Mediterranean Basin, where viticulture has strong historical roots. According to the latest figures from OIV (International Organization of Vine and Wine) – 2018 World Vitiviniculture Situation – the global area under vine is of approximately 7.5 million ha, with almost 75 million tons of grapes produced worldwide (37% in Europe, 34% in Asia and 19% in the Americas), a world wine production reaching almost 280 million hl, and a world wine trade of about 30 billion euros. However, despite the high value of this sector, it is vulnerable to climate change, mostly because grapevines are very sensitive to the atmospheric conditions, such as temperature, precipitation, radiation and wind, being also very susceptible to hail, heavy precipitation and droughts. Therefore, research on the potential impacts of climate change in viticulture is of utmost relevance for the winemaking sector so as to develop and implement suitable adaptation and risk reduction measures. All wine regions will be at risk under climate change, but those located in warm and dry climates are particularly threatened and deserve more attention. This is the case of the wine regions in the Mediterranean Basin. Although a wide range of potential adaptation measures can be outlined, varying from the short-term to the long-term, they must take into account terroirs, regional specificities and wine typicity in order to be effective. A discussion panel between scientists, technicians and wine companies will be promoted within this session, providing knowledge exchange and capacity building, aiming at contributing to a more resilient winemaking sector.
