Answer 1

• Desertification refers to the conversion of a fertile region into a dry region similar to a desert.
• Desertification in Africa is moving at 5 km per year.
• The major causes include human activities which resulted in falling of trees and vegetation. The greenery decreased to satisfy the needs of fuel of the residing population.
• The other reason is the climate. The climate does not support agriculture or farming related activities.
• In view of the above discussed factors, desertification is estimated to gradually cover the whole of Africa in the future.

Answer 2

It had affected Africa in many different ways.

Step-by-step explanation:

Fire is a major cause of desertification in North Africa's Sahel region, where dry-land degradation is particularly pronounced. The loss of dry-lands in Africa is causing people to move to urban areas who can no longer make a living off the land.

Agricultural practices associated with poverty are a major contributor to desertification. Continuous cultivation without adding supplements, overgrazing, lack of structures for soil and water conservation, and indiscriminate bush-fires exacerbate the desertification process.
