Desertification theories

Desertification theories explain how land becomes desert-like due to environmental and human factors. Key ideas include that overgrazing, deforestation, and poor farming practices remove vegetation, leaving soil vulnerable to erosion and drying out. Climate change can also reduce rainfall, making areas more prone to turning into deserts. These processes degrade land productivity, turning productive areas into barren landscapes. Overall, desertification results from a combination of natural climate variations and human activities that disturb the balance of ecosystems, leading to loss of soil fertility and water retention, which makes the land inhospitable for plants and animals.
