Maybe I dont know how to use the search very well but ...
Is there a reason the bananas with plantation loses the hammer from the plains tile? I cant think of another resource that loses something from its base tile when improved.
Was a forest removed to build the plantation?
nope
Banana/Jungle = 4 food
chop jungle (now Banana/Plains) = 3 food 1 prod
plantation = 4 food
(obviously building/tech bumps could alter these numbers)
I think the reason is pretty obvious...
You lose production because your people are busy eating bananas![]()
Actually its
Banana/Jungle=3 Food
Banana/Plains=2 food 1 production
Plantation= 4 food. (5 with Granary, 6 with Fertilizer)
The Plantation Adds 2 food and removes 1 production.. giving a net change of 1.. like any other improvement)
I used to go with the theory of more and more production was the key, but I tried to just go crazy with food on a city in my last game and got the pop up to 52 by the end using all farms and one or two lumbermills. Of course at the end of the game my production was through the dang roof, but it was also that way getting up there as well, you have to have a big population to even use all of those tiles youre improving anyway, and when you run out of tiles the specialists do great things for you... moreover, when you are out of specialist slots the unemployed citizens still give you production as well. All in all I think a 1 hammer sacrifice is worth it for 1 more food.
By choosing the right policies, and/or playing India.how do you cover the unhappiness
This is the only resource that by improving it you actually lose something from the base tile. (I dont count chopping forests as losing something)

Try putting Mines, Camps, TradingPosts & what else... then you'll actually see that most improvements do shuffle up whatever default Yields were there.
Ill have to double check, but I'm fairly certain my banana plantations are give 5 Food. I'll check again tonight and repost
Mine also give 5. So this tile feeds itself and a mine (with 1 food left) or itself and 3 lumbermills (as they give 1 food themselves) not to speak of the granary giving also +1 food. So they are excellent tiles (without the annoying probability of a citizen dying by eating them, what we had in CivIII).
Jungle tiles normally don't have production on them and it's common to lose 1 production, when chopping wood, so I actually don't fully get the prob here.
