Irrigation

Irrigation is a terrain modification performed by a settler, worker, or engineer. Irrigated terrain usually produces more food for a city than before it was irrigated.
== Mechanics ==
* The irrigation order can only be given to a settler, worker, or engineer.
* The terrain to be irrigated must have one of its four sides adjacent to a water source - sea, lake, river, or another irrigated square; a city does not count unless it contains a river.
* A worked irrigated square generates one more unit of food per turn.
* A square cannot contain both irrigation and mine; building both will replace the first.
