Desertification is the transformation of arable or habitable land to desert, as by a change in climate or destructive land use.[1]<br>
<br>
More than 27% of China is already covered by desert, and the problems associated with desertification have been written about since the 4th century B.C.  According to records, dust storms came to Beijing once every 7 or 8 years in the 1950s, then every 2 or 3 years in the 1970s, but have become an annual problem by the early 1990s.[4]<br>
<br>
The amount of desert nationwide in China is increasing by upwards of 3,500 sq km every year! At the same time, the Gobi desert is advancing at 3.2 km per year on Beijing; at this rate, it is estimated to be on the outskirts of the city by 2070![3]<br>
<br>
In the seven years ending the 20th century, the total area of land-turned desert exceeded 1.69 million sq km, or 17.6% of the country's territory.  This is believed to cause economic losses exceeding US$6.5 billion each year.[2]<br>
