The World Food Program is ringing the bell at increasing risk of food shortage.

There is a lack of rice production due to drought and demands

France consider that food supply will be a military challenge in some years (the two other points are Russia, and islamic threat).

There is sever drought in Amazonia and the whole south america.

India stopped to export rice (or weat? I don't remember), due to aome China agression pretext.

so yes, banana price rise and the other food goods will follow.
