Cause of desertification
In China, so many trees were cut down for the steel industry during the Cultural Revolution that one fifth of China’s landmass has become deserts.
In some places, the over-use of land due to an increasing population may cause desert fringes to form different microclimates which may not be able to support the original biodiversity well. In other places, deserts fringes are very distinct.
To meet the need for food to feed the growing population, grazing land is needed. Grazing further reduces the number of flora that can hold the soil together. The over-use of land causes soil to be impacted and soil erosion can take place easily.
The breeze causes sand particles in deserts to move, forming sand dunes. These may then encroach on the human habitats. |
