Food production can afford to be so energy inefficient because without the taxes that get it expensive for road transport use, fuel is still quite cheap, this is bad for the environment, but at the same time it can help avoiding a disaster on this front, as if and when it will be really necessary, there will be plenty of room for efficiency improvements, not to mention that the rich part of the world currently wastes an awful and shameful amount of food, we can and we must improve on that front too.
It's more likely that agriculture (and breeding and some food processing too) will have to become very soon a lot more efficient on water use, I guess.
