What areas in the world are fast becoming desert?

Regions experiencing rapid desertification include parts of the Sahel in Africa, the Middle East, and areas in Central Asia. Factors such as climate change, deforestation, and unsustainable agricultural practices contribute to this phenomenon. The expansion of deserts threatens local ecosystems, agriculture, and human livelihoods, exacerbating food insecurity and displacement. Additionally, regions like the southwestern United States are facing increased aridity due to prolonged droughts and rising temperatures.
