Irrigation can improve the agricultural production of a city’s terrain. (The form of gov-
ernment you rule under can limit the improvement. See “Governments” in Chapter

for details.) A suitable square can always be irrigated if
it shares a side or a diagonal with a source of fresh water (terrain with a river running
through it, a freshwater lake, or another irrigated square). Sometimes you might find it
necessary to irrigate squares to which your city has no access in order to extend irri-
gation into squares the city uses. After you’ve discovered Electricity, your Workers can
irrigate squares without fresh water.When your Worker is in the appropriate square, click
the Irrigate order or press [I].

To have the Worker irrigate the square they’re in, then irrigate every square in a con-
tinuous path linking the Worker’s current location to the nearest city, press [Ctrl]-[I].

Clearing terrain is a low-tech, labor-intensive form of land transformation, available only
for some terrain types. Clearing improves the movement point cost of dense terrain
(although it also eliminates the defensive bonus) and provides land suitable to further
improvement through irrigation and such. Sometimes, a terrain square might need to
be cleared to allow for irrigation, then later reforested to restore valuable resources.When
your Worker is in the appropriate square, click the Clear order or press [Shift]-[C].

Building Fortresses can be essential for defense of terrain that is not a city site. Fortresses
provide a defensive bonus to rural or frontier units in the same way the Walls improve-
ment benefits urban defensive units (see “Combat” for the full details). When your

Mining terrain allows full exploitation of the natural resources present—it increases the
number of shields you collect from the square.When your Worker is in the appropri-
ate square, click the Build Mine order or press [M].
