Desertification Statistics

Desertification is already reshaping livelihoods at massive scale, with about 12 million hectares of productive land turning to desert each year and 2.6 billion people relying on affected landscapes. See how pressures such as overgrazing, drought intensification and soil salinization translate into real losses, from 12% lower crop yields on affected lands to $42 billion a year in lost ecosystem services and rising costs that reach $8.4 trillion by 2050.

Statistics that fail independent corroboration are excluded.

Desertification is already eroding livelihoods across more than 100 countries, with 2.6 billion people relying on land that is being pushed beyond its limits. Climate change is making the situation sharper, increasing aridity in 74% of drylands, while drought frequency has risen by 29% since 2000. When you map what drives land from overgrazing to salinization, it is striking how quickly different pressures stack up to turn productive ground into dust.
