An area of land nearly a third larger than India has turned from humid conditions to dryland – arid areas where agriculture is difficult – in the past three decades, research has found.
Drylands now make up 40% of all land on Earth, excluding Antarctica. Three-quarters of the world’s land suffered drier conditions in the past 30 years, which is likely to be permanent, according to the study by the UN Science Policy Interface, a body of scientists convened by the United Nations.
