Difference between Desertification and Desertification

Desertification is founded by the action of man and desertification is a natural process. Desertification is the step and effect of degradation where formerly fertile lands are converted into desert. Desertification is used in scientific terms as a phase generated by the intervention of man or also called anthropic causes.

The suppression of the amount of available water by extending the periods of drought in certain places can lead to the desertification of a place. The most common causes of desertification are overgrazing, deforestation and unsustainable farming practices.

Desertification is the formation of deserts through a natural phase. Some of the natural causes of this process can be associated with the following:

 
  • Astronomical factors : the Milankovitch cycles that contain the cycles of variation of the inclination of the Earth’s axis, the cycle of orbital eccentricity of the Earth, the precession of the equinoxes and the cycle of oscillation of the elliptical plane that, combined, reinforce the production of glacial periods.
  • Geomorphological factors : the orogeny or formation of mountains and the distribution of continental masses.
  • Dynamic factors : all the phenomena related to the geological and biological activities of the Earth.

One of the most common examples of desertification is the Sahara desert, which thousands of years ago was a fertile and productive land.
