Explanation:
Detailed explanation-1: -The United Nations’ official definition says desertification is land degradation in typically dry areas resulting from various factors, including climatic variations and human activities.
Detailed explanation-2: -Both natural variability in climate and global warming can also affect rainfall patterns around the world, which can contribute to desertification. Rainfall has a cooling effect on the land surface, so a decline in rainfall can allow soils to dry out in the heat and become more prone to erosion.
