Part 5/10:

Despite the Sahara's history of desolation, recent decades have seen a curious phenomenon: an increase in vegetation in various regions of the Sahara, particularly in the Sahel, a transitional zone. Satellite data indicates that parts of the Southern Sahara have experienced a notable uptick in plant cover in the past 40 years. This resurgence, dubbed “Greening the Sahel,” can be primarily attributed to alterations in rainfall patterns, showing a modest increase in precipitation that is sufficient to sustain plant life.
