9 December 2024
Riyadh, Saudi Arabia Even as dramatic water-related disasters such as floods and storms intensified in some parts of the world, more than three-quarters of Earths land became permanently drier in recent decades, UN scientists warned today in a stark new analysis.
Some 77.6% of Earths land experienced drier conditions during the three decades leading up to 2020 compared to the previous 30-year period, according to the landmark report from the UN Convention to Combat Desertification (UNCCD).
Over the same period, drylands expanded by about 4.3 million km² an area nearly a third larger than India , the worlds 7th largest country and now cover 40.6% of all land on Earth (excluding Antarctica).
In recent decades some 7.6% of global lands an area larger than Canada were pushed across aridity thresholds (i.e. from non-drylands to drylands, or from less arid dryland classes to more arid classes).
