Desertification is one of the biggest environmental problems worldwide because of its great social, economic and environmental impact. Desertification is the degradation and ecological deterioration of fertile and productive soil, which loses its biological potential. That is, it is the destruction of arid, semi-arid and sub-humid lands. Desertification should not be confused with erosion, even if they are related to its great destruction to the soil and land surface.
What causes desertification?
The problem of desertification is mainly caused by:

- Economic development model.
- Exploitation of natural resources.
- Conventional agriculture not sustainable.

- Climate change.
- Global warming.

What are the consequences of desertification?
Among the main consequences of the problem of desertification are:
- Depletion of natural resources.
- Loss of productive fertile soils.

- Loss of biodiversity and ecosystems.
- Affectation in food security.
- Economic losses.
- Reduction of agricultural production by 50%
- Alteration in the quality of the elements air, water, soil, flora and fauna.
- Increase of climate change.
- Ecological imbalances
- Weakening of the quality of life.
Therefore, given these consequences and impacts of the problem of desertification it is important to put into practice the following measures to combat this environmental problem such as:
- Conservation and sustainable use of natural resources.
- The reforestation.
- Organic farming
- Social, economic and environmental sustainability
- Eradicate poverty.
- Promote sustainable development.
- The environmental sanitation.
- The recovery and restoration of the lands.
- Public environmental policies.
