Encroaching deserts due to global warming the ‘challenge of our times,’ study says [2]
The study by the United Nations University, [7] produced by more than 200 experts from 25 countries, suggests climate change is making creeping deserts "the greatest environmental challenge of our times".
One-third the Earth's population - about two billion people - are potential victims. Overexploitation of land and unsustainable irrigation practices are making matters worse, it says, while climate change is also a major factor degrading the soil.
