If I recall, intelligence is 2 components, pattern recognition (hey the wheat grows like shit here, but better over there) and then problem solving. I would add ability to learn as well, because thosw 1st 2 components are no good if you forget what you learned lol. This is why Zimbabwe/Somalia are fucked in that regard. Agriculture, modernized at the very least, escapes them.
