Desertification is the persistent degradation of dryland ecosystems.It affects the livelihoods of millions of people. In 2000, drylands, which occupy 41% of Earth’s land area, were home to a third of the human population.A significant portion of drylands are already degraded, and the ongoing desertification threatens the world’s poorest populations and hinders the prospects of reducing.
