Explanation:

Desertification is the means whereby land is degraded in areas such as the arid, semi-arid and sub-humid lands due to reasons such as human factors and climate change.

Also, we look at the Sahel as the area that is located along with the areas of the Sahara desert that has rainfall withing 200 to 600 mm as average within a year.

However, the harmattan contributes to desertification in the Sahel with the explanations below:

isaac newton first proposed that earth was not perfectly round. instead, he suggested it was an oblate spheroid—a sphere that is squashed at its poles and swollen at the equator.

the idea of the earth being a flat disc is also inconsistent with the fact that a given lunar eclipse is only visible from half of the earth at a time. the only shape that casts a round shadow no matter which direction it is pointed is a sphere, and the ancient greeks deduced that this must mean the earth is spherical.
