Yes, this is true!
Artifacts are objects made by humans. For example a vase or a plate used by Greeks in the ancient time is an artifact. Archaeologists do recover and analyse such vases or place in order to find out how people lived in the past and how they used those objects.
Answer:
Dry and barren land becomes desert.
Explanation:
Desertification is a process when the desert expands at the expense of an area that was not a desert. Basically, an area that was a steppe, for example, because of mismanagement or climate changes, can gradually become a desert as it gets drier and the land barren, so the desert will replace it.
In Africa, desertification is a big problem. Both, human mismanagement of soil and climate change have resulted in damaging the biomes that are close to the deserts, mainly the steppes. The soil is often left without nutrients so it can not support vegetation, which in turn also affects the water sources and precipitation paterns in a negative manner. The land becomes barren and drier than it was, and being close to the desert, the winds quickly manage to cover the surface with sand, converting it into a desert.
