* Interpretation 2: Sugarcane etc. gets higher yields but only because corporations invest more money & [[fertilizer]] into growing it. First-world countries want sugar, and their spending power makes it happen (highly-valued currency). The same economics doesn't care about Africa's grains, because grains can be grown "at home" in rich countries. Perhaps if African grain farmers had more access to resources{{x|fertilizer? something else? depends on the specific case; this would be a whole topic in itself}}, grains would yield just as many calories as sugarcane. | * Interpretation 2: Sugarcane etc. gets higher yields but only because corporations invest more money & [[fertilizer]] into growing it.
