Most areas became desert after deforestation, many times due to earlier civilizations of humanity, many speculate that these were often largely influential in the falls of empires. A good example would be Iraq, when it was still Babylon there were a lot of trees, forests, and marshes there. The deforestation around the mountains eventually caused droughts, which turned it to desert and contributed to the fall of an empire. There is evidence of this with nearly every fallen civilization that wasn't directly caused by war, but even then often the wars happened due to scarcity caused by similar events in neighboring nations.
