Irrigation increases food production. Only squares adjacent to fresh water (river or lake) or to another irrigated square may be irrigated. After the discovery of Electricity, you can irrigate a tile without proximity to fresh water.
Since Play the World it is possible to irrigate through the city square.[1] In other words, if a city square has an adjacent irrigated tile, any other tile adjacent to that city square can be irrigated too. And unlike normal irrigation, cities can be built on hills.
| Terrain | Produces | with irrigation |

| Plains | 1 food | 2 food |
| Hills/Tundra | 1 food | Cannot be irrigated |
| Mountain | 0 food | Cannot be irrigated |
Workers are ordered to irrigate by pressing [I] or the "Irrigate" button.
