I did say a starved region would revolt quicker, not than the revolt would 'save' lives or resolve the hunger... 
Probably would be first riots, then revolts and finally massive emigrations... if they have a non-starved neighbour to go.
A day after it revolted it probably wouldn't all that much to emigrate and anyways regions that are nonstarving only do anything if they are in crap conditions too as otherwise there is no room for them to emigrate. Also decimating a region every time a region starves for a day is no good as quick revolts combined with the riots would cause that and it sucks waiting for ever to have a decent region again which is basically why you made this thread IMO.
