The Columbian Exchange: A History of Disease, Food, and Ideas by Nathan Nunn and Nancy Qian that paper has very good info on agricultural products and their production in various countries moi.,but what i don't get is your question., ...
but what was the effect of 1492 and all that on Islam?... which is trying to couple that work with Islam..
it is interesting to explore that question in a slightly different angle.. Instead of European colonization of old world during medieval times
say some 14th century to end of 19th century ,If Islamic conquest occurred and Islam spread in to the so-called old world North and south american continents.,
what would such Islamic North and south american continents look like now? that is an interesting question ....
