First off I'm sorry if this is the wrong place to ask this, please feel free to move as needed.

I want to create a rough regional map. The main reason for conflict in this land is the presence of its more localized highly fertile areas and the more populated but dry/rocky terrains. Basically who ever owns the fertile lands gets to feed there people, decide who to sell to and has a leg up in the wars.

Should I share what I know/ask my questions here or find another more appropriate site? My questions seam to be more about making my map realistic then on the map making process. Sadly I have a time frame of only a few days to complete this along with a few other projects. If this turns out to be the place for me I will ask my questions here and post my map when its done. If not then any suggestions on places to go would be great. Thanks for the help.
