What affect does the Sahel's climate and physical characteristics have on population distribution?

The Sahel has been labeled as one of those regions with the danger of overpopulation. It has been described with adjectives such as semi-arid, hot, dry, windy or sunny.

Sources have it that the G5 Sahel countries which include Mali, Niger, Burkina Faso, Mauritania, Chad will increase from about 84 million inhabitants in 2019 to 197 million in 2050. This projection includes people under 15 years of age which comprise about 50% of the entire population.

The climate itself doesn't seem to deter population growth. What seems to be occurring is sedentarization. This is due to rapid desertification and drought which have persisted for some time.

Explanation:

Sedentarization refers to the choice of a group of people who usually are very nomadic or migratory to settle permanently in a place.

This is usually due to a more favorable weather and topography which supports agriculture.
