Which of the following is not a cause of desertification in West Africa?

The option that is not a cause of desertification in West Africa is constant high temperature. Desertification is the process of fertile land turning into desert due to various factors, including human activities and climate change. Some of the main causes of desertification in West Africa include deforestation, overcultivation, and overgrazing. Deforestation reduces the amount of vegetation that holds the soil in place, making it more vulnerable to erosion and degradation. Overcultivation and overgrazing lead to soil depletion and compaction, which reduces its ability to hold water and support vegetation. While high temperatures can exacerbate the effects of these factors, it is not a direct cause of desertification.
