Desertification is a complex issue with several primary causes, which are: overgrazing, removal of vegetation cover, excessive fuel wood collection, unsustainable farming practices and excessive tree felling. As desert locales are converted to farmlands to sustain large agricultural operations, overgrazing is increasingly problematic. Most factors contributing to deforestation are man-made, such as overgrazing, and threaten the lives of people and organisms in affected areas.
In addition to overgrazing, the removal of vegetation cover poses significant risks too, by ridding the land of its defenses against erosion and water absorption. Fuel wood collection and clear-cutting accelerates deforestation, too, by removing deep, water-absorbing roots from the ground and washing away nutrient-rich soils. Lastly, negligent farming practices waste natural resources and contribute to deforestation.
