Question

1. what has is forcing people in the sahel region to leave their lands and move? how do they survive?

Explanation:

In the Sahel region, desertification (land degradation leading to desert - like conditions) is a major factor forcing people to leave. As the land becomes less fertile and drier, traditional livelihoods like farming and pastoralism are affected. To survive, they may migrate to more fertile areas or urban centers. Some may also engage in alternative livelihoods such as petty trading in the new locations.

Answer:

Desertification is forcing people to leave. They survive by migrating to more fertile/urban areas and engaging in alternative livelihoods (e.g., petty trading).
