Desertification is the process by which land degrades, losing its fertility and becoming increasingly arid. It is a major environmental problem that affects over 25% of the Earth’s land surface and is expected to worsen in the future due to climate change. According to the UN, desertification and drought affect about 1.5 billion people.
There are a number of factors that can contribute to desertification, including climate change, deforestation, overgrazing, and poor agricultural practices. The effects of desertification can be devastating, leading to food shortages, water scarcity, and the displacement of people.
