But the city they're built in in the screenshot doesn't have any floodplains. In fact, it only has one single desert tile (which is quite odd). My best guess is that it adds a good yield to the tile it's built on instead of boosting the yields of all tiles of a certain kind.
Bear in mind that these screenshots are always heavily staged to show us certain aspects of the game and aren't necessarily meant to be taken at face value.
