I urge you to look at "Climate change in the Fertile Crescent and implications of the recent Syrian drought" [0] linked to in the article. It describes mass displacement in Syria following a severe 3 year drought, which in turn have contributed to the conflict there.

While not every drought is going to lead to a civil war its a dramatic example of how the type of market adjustment you are talking about is not a smooth, painless experience.
