Describe 2 ways that humans have contributed to the desertification in Southeast asia?

@AlexandervonHumboldt2,

Pollutoin is a huge one and destruction of forests and land ... ie all the big towers and smog

One way that humans have contributed to the desertification in Southeast Asia is that humans domesticated grange animals to the area. The area had a voluminous amount of vegetation. A second way is that humans engaged in substantial open mining which altered the course of water sources to the agricultural areas of the land.
