EXCERPT

Desertification is a phenomenon that ranks among the greatest environmental challenges of our time. Yet most people haven’t heard of it or don’t understand it.

Although desertification can include the encroachment of sand dunes on land, it doesn’t refer to the advance of deserts. Rather, it is the persistent degradation of dryland ecosystems by human activities — including unsustainable farming, mining, overgrazing and clear-cutting of land — and by climate change.
