The August report from the Global Drought Observatory said 47 per cent of the continent is experiencing "warning" conditions, meaning the soil has dried up, while 17 per cent is in "alert" status, with vegetation showing signs of stress.
The severe drought has affected many regions of Europe since the beginning of the year and was expanding and worsening as of early August, the report said.
Water and heat stress have "substantially" reduced summer crop yields, with the most affected crops being grain corn, soybeans and sunflowers, the report said.
