Final answer:

Overgrazing, water table depletion, and farming are factors that contribute to desertification.

Step-by-step explanation:

Desertification is the process by which fertile land becomes desert-like in its characteristics, making it unsuitable for agriculture or habitation. There are several factors that contribute to desertification, including:

  1. Overgrazing: When livestock graze too heavily on grassland, it can lead to soil erosion and desertification. The roots of grasses help hold soil in place, but overgrazing prevents grasses from regrowing and maintaining the stability of the soil.
  2. Water table depletion: Excessive withdrawal of water from underground aquifers can lower the water table, which in turn dries out the soil and contributes to desertification.
  3. Farming: Unsustainable farming practices such as overcultivation, use of chemical fertilizers and pesticides, and poor irrigation techniques can deplete nutrients and moisture from the soil, making it more susceptible to desertification.
