The process by which natural or human causes reduce the biological productivity of dry lands is known as desertification. Here are the steps of how it happens:

1. Overgrazing: This is the most common cause of desertification. When animals eat too much of the plant life in an area, it can lead to soil erosion because there are not enough plants left to hold the soil together.

2. Deforestation: When trees are cut down, it can also lead to soil erosion because the roots of the trees are no longer there to hold the soil in place. This can lead to the creation of a desert-like environment.

3. Farming practices: Certain farming practices can also lead to desertification. For example, if a farmer does not rotate his crops, the same nutrients are continually taken out of the soil, which can eventually lead to the soil becoming infertile.

4. Climate change: Changes in the climate can also lead to desertification. For example, if an area becomes hotter and drier, it can lead to the death of plants, which can then lead to soil erosion.

5. Urbanization: The expansion of cities can also lead to desertification. When land is cleared for buildings, the soil can become compacted, which can lead to water runoff and soil erosion.

In conclusion, desertification is a serious environmental issue that is caused by a variety of factors, both natural and human-made.
