My guess here on Cuba's latest problems with food production stem from a lack of cheap fertilizer.  During the Soviet era when Cuba was embargoed, they ramped up their own local food production to keep everyone reasonably well fed.  Likely they were abl to do that because although imports of food were embargoed and they didn't have the FOREX to pay open market prices, they were able to get cheap fertilizer.  Now that fertlizer prices have gone up and Cuba is competing for a limited supply with all the rest of the poor countries of the world, they aren't getting enough and can't meet their production goals.  Which generally means that Cuba will now depopulate fairly rapidly as food refugees stream to the FSoA where food abundance is still fairly common, although stories today also about the NYC homeless not getting enough rations also.

This problem is probably still a little ways off for most of the FSoA citizens who have been here a while and are "in the system", getting their SNAP cards every month.  Only a matter of time though before that begins to break down.  So enjoy your last helpings of fast food plenty and gorge on high fructose corn syrup soft drinks while you can.  We may finally see the end of Fat Amerikans.

Rationed food kept Cubans fed during the Cold War. Today an economic crisis has them hungry
