do cities spread irrigation?

[Herrhals]

I think I noticed it one of my games, I was a bit surprised.

But I need confirmation that irrigation is spread through cities, or if there was another factor I missed.

Ex. there is a river, then my city is on it, then corn on other side of city. No natural irrigation, but as I recall, I researched CS and I got +1 on the corn.

confirm?

Depends on what type of tile they are founded on. If the tile they are founded on can spread irrigation, it maintains this ability. If not, then no.

Example - founded on grassland - yes
- founded on hill - no

 

[Cusanus]

They do.

Unless they are placed on a hill.

(Not shure about cities placed on a desert tile - but I think they do spread irrigation, too.)

Cities placed on desert tiles spread irrigation. It's only on hills they don't.

 

[Shurdus]

Cities placed on desert tiles spread irrigation. It's only on hills they don't.

What about tundra?

As long as you researched civil service I think the city will spread irrigation if the tile the city is on can be irrigated.

 

[Bostock]

That wouldn't account for the desert, if that part is true.

 

[Smokey McDope]

desert on a river is floodplains, which can be irrigated. when you settle a city on flood plains the tile turns to desert, but can spread irrigation

 

[Windsor]

Cities placed on tundra do spread irrigation. As I said, it's only when a city is placed on a hill it does not spread irrigation.

All flatland city tiles spread irrigation. No hill tiles do so.

Actually TMIT, that's not quite true. Farmed hills can spread irrigation. Though I think that can only happen on one specific mapscript under one circumstance (rice on a hill which occurs on a rainforest script).

if you worldbuilder a farm on any land tile (maybe not mountains), they spread irrigation
