I wouldn't be surprised. Droughts have toppled empires since the beginning of time. People can put up with a lot, but once they go hungry for an extended period of time, you can bet they'll want the status quo to change, and to change fast. A drought in Russia was one of the indirect causes of the Arab Springs revolution a decade or so ago.
