Published: 8 September 2026 · 1 min read

What Happened

A new study projects that Earth's drylands could expand to cover more than 40% of global land area by 2100. Researchers warn that rising temperatures are expected to make many already-dry regions even drier, increasing water scarcity and environmental stress.

Key Takeaways

Expanding drylands could worsen water shortages, ecosystem degradation and desertification, posing major challenges for agriculture and sustainable development. Australia, Brazil and parts of Africa are among the regions expected to see significant changes.
