Two primary causes of desertification in South America are deforestation and unsustainable agricultural practices. Deforestation, particularly in the Amazon rainforest, reduces vegetation cover, leading to soil erosion and loss of moisture. Additionally, overgrazing and the use of chemical fertilizers in agriculture degrade soil health, further contributing to land degradation and desertification. These factors combined exacerbate the vulnerability of ecosystems and local communities to climatic changes.
