Explanation:
Desertification is the process by which fertile land becomes desert, typically as a result of drought, deforestation, or improper/ excessive agriculture. Both overgrazing and poor cultivation can contribute to desertification, as they both lead to the degradation of the soil and its inability to support plant life. Overgrazing removes the vegetation that helps to hold the soil in place, making it more susceptible to erosion. Poor cultivation practices, such as over-tilling and over-irrigation, can also damage the soil structure and make it less productive.
