There are many lists of the problems with desertification. If you want more you can find it in the internet or google.

• One quarter of the earth's surface is threatened by desertification -- an area of over

3.6 billion hectares.

• Since 1990, 6 million hectares of productive land are lost every year due to land

degradation.

• The world's drinking water supplies have fallen by almost two thirds since 1950.

• Every year, 12 million people die as a result of water shortages or contaminated

drinking water.

• Desertification threatens the livelihoods of one billion people and has already

made 135 million people homeless.

• Every year, desertification generates income losses totalling USD 42 billion.
