At least three African nations will need to import more corn this year after extreme weather from cyclones to drought devastated crops, sparking some unusual trade flows. Corn is a staple grain across much of sub-Saharan Africa, where it’s milled and cooked with water to form a porridge or stiff dough. Zimbabwe, Mozambique and Kenya are all expected to see imports surge this season to offset dwindling harvests. That may spur neighboring Tanzania to export a record amount, and some grain may also be sourced outside the continent. (Bloomberg)
