...only half a century, an estimated 251,000 sq. mi. (650,000 sq. km.) of farming and grazing land has been swallowed up by the Sahara along that great desert's southern fringe. In one part of India's Rajasthan region, often called the dustiest place in the world, sand cover has increased by about 8% in only 18 years.

By last week the victory was in sight: not only was the yield per acre good, but the wheat itself was rich in protein and sure to command top prices on world markets...
