Washington D.C. [USA], Jul 13 : Wine lovers may soon be left wanting for more as a recent study has found that rising temperatures are affecting wine production from hotter countries.
Slight increases in temperature in Mediterranean regions from global warming could potentially result in labour, productivity and economic losses for the European wine industry, the article suggested.
Researchers studied the effects of high temperatures on the labour output and productivity of manual agricultural grape-picking workers in the wine production industry in Cyprus, who often work in conditions of up to 36 degrees Celsius.
They found that higher temperatures in the working conditions during the summer correlated with a significant labour loss of up to 27%, due to the environmental heat causing increased perceived exertion on worker's metabolic and cardiovascular systems and resulting in reduced output.
When temperatures increased, there was also a 15% decrease in the amount of time workers were able to carry out their duties due to the increased need for irregular and unplanned work breaks.
These findings demonstrate that workplace heat, specifically in European agricultural workers, is accompanied by significant labour and productivity losses.
With the wine industry comprising of 0.2% of world GDP, increased temperatures from global warming may negatively impact the industry and even potentially result in large losses worldwide.
For this study, the authors specifically chose to study grape-picking workers, as the production of wine is still largely dominated by manual labour unlike other industries and therefore the effects of global warming on workers in this industry is highly likely to more prevalent.
The authors warned that this research should not be considered an exhaustive large scale study of the impact of global warming on agriculture workers, and broader studies involving more workers and different locations should be undertaken in order to full assess the full impact.
The study appears in the journal Temperature..
