Food

Food is produced by farms and used to feed cities and combat units. Without food, a city's population will begin to shrink and units will lose morale and will be unable to fight, defend the walls, or put down rebellions.

Units will automatically consume food when inside a camp or city, or while within the yellow resupply radius that surrounds it. If there is insufficient food locally to feed all of your units, the city will automatically try to move food along unblocked supply lines.

All combat units can carry a few weeks worth of food to supply them when they are out in the field. Units will automatically try to pickup food when they leave a city's supply range. How much food a unit can carry and how quickly it is consumed depends on the unit's stance, their officers and any assigned general.
