desertification and The Dust Bowl, writing homework help

I’ve attached my research paper and I would like someone specialize in Anthropology. 

I need to expand the paper it by a minimum of 3 pages double space .expand this discussion about the dust bowl and desertification to Saudi Arabia and the challenges and successes that you have had in food production. 

It does not has to be Saudi Arabia but this’s as suggestion from my instructor.

And the most important thing that make sure that will be in the level of writing that showing on the research.
