Nowadays, 25% of land in the world is under the threat of desertification. There
are four major regions suffering from frequent sand storms: North America,
Central Africa, Australia and the Middle East Asia.

In Africa, during the early-70s and mid-80s, the southern Sahara suffered a lot
from sand storms. It was due to long lasting drought and over cultivation by the
people. These, in turns, came with the after-effect of grassland deterioation,
barren farmland and thus intensifying the sand storms. This resulted in the
contamination to the surrounding areas.

In North America, the deserts are widely distributed in western US and the north
part of Mexico. In the nearby regions of the desserts. Sand storms are common
and there may even be so-called 'Black Storms' swirling around the vast plain.

In Australia, 75% of lands are in the categories of drought earth or semi-drought
earth. Sand stroms are frequent, which maybe 5 times or more a year, in the
central part and the west coast. The climate is extremely dry in most of the area.
Accompanying with the effect of cultivation and animal farming, vegetation are
being ripped away and those factors lead to the exposure of the surfacing soil
which will end up with desertification.

As in the Mid-east Asia, the 5 countries among the region, is experiencing rapid
development. Blooming population, excess consuming of underground water,
uncontrolled logging of forests, overcultivation of animals, will result in grassland
deterioration and desertification. Consequently, the salt-land area increase to
the extent of over 15000 square km.

1/4 of the danger which suffers the desertification of the global area of land at present. There are 4 heavy sandstorm pilosity areas in all in the world: North America , Central Africa , Australia and Central Asia.

The south reason in Sahara Desert of Africa, from the beginning of the seventies of the 20th century to middle period of the eighties, because droughts and locals graze and cultivate excessivly year after year, cause the meadow to degradate, the field goes out of cultivation, the desertification land spreads , the sandstorm is aggravated , locals' living environment worsens sharply. The frequent sandstorm still brings disaster to other areas.

The desert in North America is distributed in west and north of Mexico of U.S.A.. With desert bordering desert arid district, the sandstorm takes place occasionally . Even the black storm of the name of history has broken out on the big plain.

Australian 75%, land of area the universe drought and half the universe on land district. The regional sandstorm of middle part and western coast is the most frequent, there are 5 times equally every year. Because a lot of places are dry, in addition, cultivation and grazing, the soil top layer lacks the vegetation to cover, have caused the gradual desertification of the land.

5 countries of Central Asia are because of population's fast increase, people indiscriminate felling of trees in the forest in order to irrigate the water excessivly, overload and graze, degradate in the meadow, the desertification is very serious. The solonchak of Central Asia is vast in area, reach 150,000 sq. km.
