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.
