Desertification is the inability of ecosystems to fulfill their regulatory function caused by deforestation, overgrazing, and overworking the soil.
<h2>What is desertification?</h2>
Desertification is a phenomenon that implies the loss of fertile soils due to climatic variations and human activities.
- The three main causes of desertification are overgrazing, deforestation, and unsustainable agricultural practices.
- Overgrazing and deforestation destroy the protective vegetation layer that covers arid and semi-arid regions.
Therefore, we can conclude that desertification is the process of ecological degradation through which areas of land that were fertile and productive are transformed into deserts.
