Wheat is aging prematurely because of climate change

Global warming can make wheat premature aging and reduce harvests worldwide, a study is published in Nature Climate Change.

The Wheat and Wheat Quality Improvement Research Center (CIMMYT) said wheat - the most widely grown crop on earth is harvested in temperate regions on more than 220 million hectares. In some countries, quality wheat seeds contain up to 50% of calories and 20% of protein nutrition.

In 2010, Russia's drought and forest fires pushed grain prices around the world for two consecutive years. This is a warning for food supply related to climate change.

Greenhouse experiments show that rising temperatures, especially at the end of the season, can increase the aging process of wheat.

David Lobell, Stanford University research and colleague team leader, continues to experiment to assess the effect of temperature on wheat. They found that if the average temperature rise of 2.0 degrees C can shorten 9 important days in the growth and development time of wheat. This reduces up to 20% of the total harvest.

"These results show that a major challenge is threatening wheat production. Therefore, we need to research so that wheat can adapt well and be resistant to hot days." experts concluded.

According to the UN Framework Convention on Climate Change (UNFCCC), it proposes to set a long-term common goal for countries around the world to limit the increase of Earth's temperature to a maximum of 2 ^° C over the pre-period. industry.
