In countries such as Germany and Belgium, periods of drought and heatwaves will be responsible for a nearly 40 percent reduction in barley cultivation, according to a new study by researchers at the University of California, USA.
Climate change threatens to affect beer production. The alert is made in a new study carried out by researchers at the University of California, USA. In countries with Germany, the Netherlands and Belgium, which are among the world's largest producers, periods of drought and hot flashes will be responsible for a 40% reduction in barley cultivation, one of the main ingredients of the drink.
According to experts, within a few decades, there will be less beer and will be more expensive. In some places, like Irish taverns, the price may even quadruple quickly, scientists believe. According to the US study, made public by the specialized publication Nature Plants, world production of barley is expected to decline by 17% following extreme weather events.
In the Czech Republic, another of the major brewers, as expected for Germany, the Netherlands and Belgium, is expected to be around 38%. In Brazil and in some East African countries, the percentage should be around 20%.
"Significant drop in supply [global] of barley will cause substantial changes in beer consumption and prices, "Steven Davis, one of the authors of the research, has already publicly acknowledged.
Although China is the world's largest consumer of the drink, the Irish are the largest drinkers per person per year and therefore the most likely to suffer from rising prices that, according to the study's authors, may rise between the 43% and the 338%. According to the researchers, if predictions are confirmed, overall beer consumption will fall by 16%, minus 29 billion liters.
