That's exactly the wrong way to go!
If the map has not many resources left, AIs should STOP building female peasants because they are useless in that state of the game (and that may be the case from star on).
The "new RMS Test" generated maps are quite playable (though not very exciting) for human players with farms and a market.
But AIs even have problems with maps with mass wood, stone and metal, just because there are no plants to harvest food from.
This really is a stupid thing, I feel.
I don't even like berry bushes and apple trees because they only block buildsides, make me gather apples but wood by accident and all got a lower gather rate (including chicken, deer, sheep, corral etc.) then fields (because u can put them right next to your city center).
The AI of cause should use them, but shouldn't need them!
