Climate Change May Wipe Out Over Half Of The World’s Wine Growing Regions

Hot regions –Italy and Spain projected will see their vineyards suffer the most!


Rising temperature as a result of climate change could wipe out more than half of the world’s present wine-growing regions as well as force vineyards to change varieties in order to keep performing.

Researchers, from Harvard University in the United States, recently discovered that 2oC of warming can cut out the amount of apt wine-growing regions by 56% or even more.

Trading their current grapes varieties for more heat-tolerant varieties could, however, assist in keeping some vineyards in full business. For instance, Mourvedre could be grown where pinot noir, merlot, and cabernet sauvignon is cultivated.

These cooler-temperatures grapes could afterward grow in new-wine producing regions, the North of their current locations.

Climate change is predicted to hit already hot regions including Spain and Italy, which both have no-more heat resistant varieties to trade.

‘Replacing Grenache or cabernet sauvignon for pinot noir, planting Trebbiano where Riesling is growing aren’t painless shifts. But they can ease winegrowers’ transition into a new and warmer world.’ Elizabeth Wolkovich of the University of British Columbia, a food and conversation scientist said.

Professor Wolkovich and other researchers discovered that if the average global temperature rises by 2oC, the regions presently apt for growing good wine grapes could shrink.

With an estimated 4oC warming, the loss of wine-growing regions could reach 85%. ‘These estimates do ignore significant changes every grower can make. We found that by switching to other varieties – Vintners can reduce the damage to about 24%.’ Prof Wolkovich added.

Other measures, including increasing irrigation and the use of shade cloths, according to the study could also help protect grapevines from higher temperatures, but only under little warming scenarios.
