In which regions is maize most intensively produced?

• A. U.S. Midwest, Central America, and parts of Brazil/Africa
• B. Southeast Asia
• C. Europe and North Africa
• D. U.S. Great Plains, Ukraine, and Russia

Answer: (A)

Maize is produced most intensively where farming is highly mechanized, input-enhanced, and closely tied to large markets. The U.S. Midwest—the Corn Belt—exemplifies this with very high yields per hectare driven by fertile soils, long growing seasons, and widespread use of fertilizers, irrigation, and modern machinery. In Brazil, large commercial farms in key producing states apply the same approach at scale, making maize a major export and staple crop. Central America also shows high-intensity production in areas near population centers and markets, where maize is a vital staple and farmers adopt inputs and practices to maximize output.

There are pockets of increasing maize intensity in parts of Africa where irrigation and commercial farming are expanding, though overall maize production there is more variable. By contrast, Southeast Asia focuses more on rice and other crops, while Europe and North Africa have climates and land-use patterns that support different crops or lower maize intensity, and Ukraine and Russia are major grain regions but historically not as intensively focused on maize as the U.S. Corn Belt or Brazil.

So the combination of the U.S. Midwest, Central America, and parts of Brazil and Africa best reflects where maize is produced most intensively.
