- Base yield: +1 Food;
- May cause the formation of Blizzards, which will bring destruction on improvements and districts, may kill Population in nearby cities, but may also fertilize tiles, giving them additional Food and/or Production base yields;
- +1 Faith Adjacency bonus for Holy Site Districts with Dance of the Aurora Pantheon;
- Additional +1 Food, +1 Production, +1 Culture with St. Basil's Cathedral.
The tundra is the third most widespread terrain in the world (after Plains and Grassland), but with just a +1 Food base yield it is far less useful. You can't build Farms there, not even along rivers (unlike in Civilization V), which severely limits the Population growth of a city, and the lack of native Production further limits its other aspects! So, unless you are playing as Russia, tundra is generally a poor location to initially settle. With Civil Engineering, Canadians can place farms on the tundra, giving them a mild boost. Cities on or near tundra will want any available resources such as Deer to make the most of the environment. Coastal cities close to sea-based resources may also circumvent some of the negatives.
It is, however, noteworthy that there are some particular resources that are found mainly in Tundra, such as Furs and Silver. Also, hard to find Strategic Resources oftentimes pop up in Tundra, or in Coastal waters near Tundra, which may also justify settling there.
Similarly to Desert, a Pantheon Belief (Dance of the Aurora) may turn Tundra into a veritable Faith factory! Simply build a Holy Site or two in the middle of the tundra, and watch your Faith yield climb off the charts!
Tundra is the semi-frozen land found in the world's colder climates. Nobody builds cities in the tundra unless they're desperate for resources (tundra tends to overlay extensive mineral and petroleum deposits) ... or they've got nowhere else to go.
