[2] Most crops are cultivated not in one place only, but in several distinct regions in diverse parts of the world.
Cultivation in these areas may be enabled by a large-scale regional climate, or by a unique microclimate.
Growing regions, because of the need for climate consistency, are usually oriented along a general latitude, and in the United States these are often called "belts".
The growing region of a traditional staple crop often has a strong cultural cohesiveness.
The need for growing fodder has also historically limited livestock to certain agricultural regions.
