Desertification is the process by which fertile land becomes desert.
Due to desertification, the soil becomes unsuitable for agriculture which results in a huge loss of food. As a result of vegetation removal, the climate changes and affects the overall environment. Due to the absence of vegetation on the land, there is no moisture in the soil to evaporate and form clouds that cause rainfall. And with less or no rainfall, it may result in more desertification.
Deforestation also increases the rate of soil erosion which happens through increased rainfall, runoff, and reduced ground debris.
