Question

Quizplus · Accepted Answer

Inappropriate land use such as agricultural clearing and overgrazing are two major causes of desertification. When land is cleared for farming or grazing, the natural vegetation that helps to hold moisture in the soil is removed. Without vegetation, the soil dries out more quickly, making it difficult for crops or grass to grow. Overgrazing by livestock can also lead to compaction of the soil, making it harder for water to penetrate and leading to further desertification.
