New World Crop Exchange in Africa

The Columbian Exchange often refers to the exchange of goods between the Americas and Europe. But the exchange occurred in other areas as well. Maize entered the Middle East by the sixteenth century and became a staple crop later in the eighteenth and nineteenth centuries. The powerful Ottoman Empire traded throughout Asia, Africa, and Europe. As trade increased throughout the world after the sixteenth century, New World food crops spread.

Several New World crops impacted Africa. The tropical regions of Africa lay parallel to those in South America. This made transplanting crops relatively easy. Europeans introduced New World crops into Africa. Out of the approximately 650 cultivated plants in the tropical regions of Africa only 50 originated in Africa. The vast majority were introduced through Asian and European trade.

Why introduce so many crops into Africa? The answer is slavery. As sinister as it seems, in order to ensure healthy slaves, Africans first had to be healthy. One determinant of a region’s health is if the population increases or decreases. When populations decrease, it usually signifies poor nutrition, impacts from natural disasters, or governmental conflicts such as war. Populations increase when food sources are diverse and plentiful.

Europeans and Asians offered tribute to African tribal leaders. Many of the tributes came in the form of plants from the New World or Asia. Maize and manioc were the most important imports. Crops such as peanuts, squashes, tomato, sweet potato, and cacao provided more variety into the African diet. Combined these crops significantly impacted agriculture in Africa.

Beginning in the late-seventeenth and early-eighteenth centuries, the world’s population began to increase. In 1650, the overall estimated population of Africa was 100 million. The population continued to increase; however, the estimated numbers reflect a decrease due to the slave trade. In other words, as the land provided food surpluses it allowed for healthier people. Healthier females menstruated over more years, increasing their years of fertility. When babies were born, more of them lived beyond infancy and into adulthood than before the introduction of New World plants. If it were not for the New World plants introduced through Asian and European trade routes, it is quite possible that the African slave trades—to the Americans and in the Indian Ocean—could not have been sustained.

Old World Crop Exchange in the New World

Europeans were good at conquering the New World. This is evidenced by the sustaining influence of Catholicism in North and South America, the cultural traditions directly transferred to the New World, and the rise in importance of sugar islands in the Caribbean. Arguably sugar was the most important Old World crop transplanted into the New World, but there were others.

Wheat, grapes, and olives were a staple for Europeans. Bread came from the wheat, wine from the grapes, and oils from the olives. The second Columbus voyage returned to the Americas with all sorts of seeds and plant clippings. Wheat, chickpeas, melons, onions, radishes, salad greens, grape vines, sugar cane, and fruits were introduced around 1494. Accounts left behind by Europeans in the New World initially reported of the massive success of these old crops in the New World. Early successes provided Europeans with hope that they could refuse the native bounty of the New World. Their ethnic hierarchy would remain intact and they would not be forced to eat corn, for example, which some believed would turn them into Indians.

These early successes were short lived. Old World crops could not be sustained beyond one or two seasons. Success came from the lowly garden crops that were usually planted on small farms or gardens of the elites. Cauliflowers, cabbages, radishes, lettuce, and melons prospered. Over time, these Old World crops were planted in larger quantities and used as export goods.

An attribute of the conquering Europeans was that they gave up on cultivating crops that would not grow in the subtropical regions of the New World. Instead, they took New World crops and introduced them to regions where they were not found. This may explain why maize is found throughout the Americas instead of where it is indigenous in present-day Mexico.

Notable exceptions to agricultural failures in the New World were sugar, tobacco, and coffee. All of these crops originated from the Mediterranean area. When they were introduced to regions in the New World, they became very successful. These staple crops became the lynchpins of what would become the massive plantation system in the New World. In many respects, sugar, tobacco, and coffee justified the use of slavery as a labor force.
