Why is the population of desert region so low

Answer 1

Explanation:

Due to absence of vegetation, no cultivation, less water Etc.

Due lack of deforestation in that are maked the land as desert... And today what we see in all over country there is lack of deforestation instead of afforestation.. 1 day all area of this country become desert if this is going on.
