"Shrubs are coming up and growing into big shrubs. This is completely different from having a bit more tiny grass," he said.
In 2008, Kropelin visited Western Sahara, a disputed territory controlled by Morocco.
"The nomads there told me there was never as much rainfall as in the past few years," he said.
"They have never seen so much grazing land," he added.
He explained it's a similar story in the eastern Sahara area of southwestern Egypt and northern Sudan, a remote desert region that he has studied for two decades.
"Before, there was not a single scorpion, not a single blade of grass," Kropelin said.
"Now, you have people grazing their camels in areas which may not have been used for hundreds or even thousands of years. You see birds, ostriches, gazelles coming back, even sorts of amphibians coming back," he said.
According to Reindert Haarsma of the Royal Netherlands Meteorological Institute in De Bilt, the Netherlands, satellite data shows "that indeed during the last decade, the Sahel is becoming more green."
