You would think with all the genetic work going on in agriculture they would be developing some trees that would grow outside their traditional climate.
Never mind the diseases, witch's broom and black pod and so forth, and never mind the pests (hey, bugs like cocoa just as you and I) such as capsid fly and brown borers and such, if the climatic and moisture conditions aren't pretty well spot on, cocoa trees don't grow well.
Perhaps the genetics chaps will find something, but, just between you and me...they'd best hurry up a bit.
FReegards!
