Sorry but I didn't get my copy for BNW, so I let the prefix as G&K How to determine what kind of improvement is suitable for your tile? For me, farm all the river-side tiles and flesh water tiles to get the extra 1F after CS. Farm also the hill with river-side to get 2F2H. 1) So what about hill with forest? You lumber mill it or chop the forest and mine it? 2) Also what about banana with jungle? You will leave it unimproved for the extra 2 science or improve it with extra food? 3) How about just a simple grassland? You farm it or trade post it? 4) Similarly, desert, would you farm it or trade post it? 5) Plain, I guess mostly farm it to let it sustainable itself. Any idea?
