According to Ridley Nelson the desertification problem and processes are not clearly defined. There is no consensus among researchers as to the specific causes, extent, or degree if desertification. Contary to many popular reports, desterification is actually a subtle and complex process of dererioration that may often be reversible.

One remedy for sand dunes is to cover the dunes with large boulders or petroleum this will interrupt the wind and keep the sand from moving. Sounds like to to me that they either need a surface mine or a few oil wells drilled in these areas.

From what I read in the article everything I said was true. Droughts do not cause it, the main culprit is Human activity. Scientists believe that bad practices in farming caused the "Dust bowl", and that better practices and water management since then have decreased the problem.

From all the information we have, human activity is the cause, more studies are being done to make sure that is correct.

The remedy you mentioned is recommended on a local level . To really understand and fight the problem we must first know the affects of overpopulation, over farming, and climate change. And the remark about needing a surface mine is absurd, I really hope you were joking, if not you have no understanding of the environment.
