Areas Affected
Drylands occupy approximately 40–41% of Earth’s land area and are home to more than 2 billion people. It has been estimated that some 10–20% of drylands are already degraded, the total area affected by desertification being between 6 and 12 million square kilometres, that about 1–6% of the inhabitants of drylands live in desertified areas, and that a billion people are under threat from further desertification.
The Sahara is currently expanding south at a rate of up to 48 kilometers per year.

Famous quotes containing the words areas and/or affected:
“In my writing I am acting as a map maker, an explorer of psychic areas ... a cosmonaut of inner space, and I see no point in exploring areas that have already been thoroughly surveyed.”
—William Burroughs (b. 1914)
“The English, besides being “good haters,” are dogged and downright, and have no salvos for their self-love. Their vanity does not heal the wounds made in their pride. The French, on the contrary, are soon reconciled to fate, and so enamoured of their own idea, that nothing can put them out of conceit with it. Whatever their attachment to their country, to liberty or glory, they are not so affected by the loss of these as to make any desperate effort or sacrifice to recover them.”
—William Hazlitt (1778–1830)
