Crop choices

One way to increase crop yields is to simply grow different crops. Food production could be doubled this way (without increasing farm land), although food quality may suffer a bit. People would have to get used to different foods, but a nutritionally balanced diet is still easily achieveable.

Ranked by calories and protein

This uses a weighted ranking system, where 50 grams of protein is considered to have equal value to 2000 kalories.

Best calorie crop + best protein crop

Calorie and protein crops are known to help each other grow. Let's see what happens if every country devoted all of its farmland to just 2 top crops:

Best weighted crop

Some crops, such as peanuts, yield a generous amount of protein and calories, but don't excel at either one. They may have been missed in the above analysis. Let's see what happens if every country devoted all of its farmland to just 1 top crop:

If the end result doesn't give a good balance of protein and calories, it might be worth trying crops top ranked by different weightings.

Proportional representation

Let's be honest: No one wants to live their lives eating just 1 food. So here's a scenario that preserves a bit more variety: Each crop gets an amount of land proportional to its yield. (...)( In other words, a crop with twice the yield gets twice as much land (which would cause its production to be 4 times higher). You get a little bit of every food, but in a way that favors high-yielding ones. )
