World’s Wine Growing Lands in Danger From Climate Change

Globally, a 2°C rise in temperature could lead to the loss of 56% of the world’s wine-growing land, while a 4°C rise could wipe out nearly 85% of it. Fortunately, scientists see the glass as half full and suggest replacing crops with other varieties in the areas concerned.

Global warming is expected to have serious consequences, according to scientists. These include rising water levels, the disappearance of many islands and cities, and the intensification of natural phenomena such as hurricanes and cyclones. Some areas of the planet will become uninhabitable due to record high temperatures. Forest fires will also become more frequent and even more destructive, with direct consequences on biodiversity. All the studies on the subject are not enough – alas – to make understand the seriousness of the situation to some who seem to think that a small increase in temperature will be quite pleasant at aperitif time. However, wine lovers may be disillusioned.

France, very famous for its wines, currently enjoys ideal temperatures for the cultivation of vines. Ideally located in the south of France, particularly in the Bordeaux region or the Rhone Valley, but also on the Italian borders, they could however suffer severely from a 2°C rise in temperatures. And this does not only concern France, but the whole world. In one study, researchers explain that a 2°C rise in temperatures could lead to the destruction of nearly 56% of wine-growing regions. A rise of 4°C could mean the loss of 85% of the world’s land suitable for this type of crop. This is an average and some regions are expected to be more impacted than others. This is the case of Spain or Italy, which could lose almost 90% of their wine-growing areas if the temperature rises by 4°C. Other regions, located further north, could on the other hand become ideal for the cultivation of certain varieties, England, for example.

Fortunately, researchers believe that it will be possible to continue producing wine even when temperatures rise by switching to other varieties. “The positive message is that we can still adapt viticulture to climate change and diversity is a very interesting tool to achieve this. But the warning is that we should limit warming as much as possible, because the more temperatures rise, the fewer options we have to adapt,” says Ignacio Morales-Castilla, one of the study’s co-authors and a researcher at the University of Alcalá in Spain. Another problem, legal this time, arises for certain wines such as “champagne” whose name can only be used if the wine in question is produced in the French region of the same name. What would happen if this region was forced to grow a different variety because of rising temperatures?
