1Lecture 34Lecture 34Horticulture, Politics, and World Affairs:Sugarcane and Plantation AgricultureHorticulture as the source of valuable commodities has had great infl uence on the interaction between nations both in antiquity and the present. The infl uence of the spice trade in the Ancient World and, espe-cially, in the Age of Exploration has already been covered in previous lectures. In the next 3 lectures, we will discuss 3 major tropical products: cane sugar, tea, and banana. Each has had profound effects on the relation between nations and peoples, effects that are still reverberating in the world today. SugarcaneSweetness is a naturally desired taste and human tongue receptors can distinguish sweetness, a natu-rally pleasant taste sensation, and the reason we enjoy fruits. In antiquity the main source of a concentrated sweet product was honey.Sugar (sucrose) is now the cheapest energy food. Sugarcane (Saccharum offi narum, Poaceae) is pres-ently the most important source of sugar followed by sugar beet. Although sugar is non-essential, modern industrial countries use an enormous amount of sugar for candy, desserts, and a myriad of products from pastries to canned vegetables. Generally, sugarcane is a crop of the humid tropical lowlands but does best in wet and dry tropics. At present, the chief world producers of sugar are Brazil and India. In North America, the chief producers are Mexico, Cuba, and the United States. Cane sugar is produced in the United States in Louisiana, Florida, and Hawaii, but Hawaii, previously a large producer, has greatly decreased produc-tion.Sugar is extracted from sugarcane, an enormous grass plant. Sugar is manufactured by cutting and squeezing the stalks for the juice. Boiling the juice crystallizes the sugar. Byproducts include the spent stalks known as bagasse which can be used as fuel for the sugar factory, and molasses, a thick brown viscous syrup which can be fermented to rum or fed to cattle. The sugar from beets (Beta vulgaris) is identical to cane sugar. The beet sugar, a temperate source of sucrose, was initiated by the French when cane sugar was prevented from reaching Europe due to a British blockade during the Napoleonic wars of the 19th century. Beet sugar is produced in the United States and Europe but must be subsidized, as the plant is not as effi cient as the tropical sugarcane.There are a number of Saccharum species (known as the Saccharum complex) that produce sugar. The most primitive species (S. spontanium) is believed to have evolved in the Himalayan foothills of Northern India. Other species are found in China and Southeast Asia. Sugarcane was cultivated in India in 400 BCE and in China by 200 BCE. The art of sugarcane cultivation and manufacture passed from India to China. Sugarcane reached Persia in the 5th century CE and in the next hundred years reached Egypt. Sugarcane began to be cultivated by Arabs in the Mediterranean basin. It reached Europe after the crusades but was expensive, primarily a luxury item and a medicine. Sugarcane was introduced to Madeira in 1432 and the Canaries in 1480 and was transported to the Hispaniola (the Island now consisting of the Dominican Republic and Haiti) by Columbus in 1493. In 1791, Captain Bligh (famous as the villain in Mutiny of the Bounty when he attempted to transport breadfruit from Tahiti) carried varieties of S. offi cinarum from Tahiti to Jamaica; previous cultivation was the thin-stalked S. sinsense and S. barberi, native to the Bay of Bengal. S. offi ci-narum is probably native to the South Pacifi c (New Guinea) and is very tall; hence known as Noble Cane. There was no sugar industry in the South Pacifi c but canes were grown for chewing. The thick-stemmed types were successful in all sugar growing areas but the other species are used in breeding to develop disease and pest resistance. Continual selection improved both yield and sugar content.The Plantation SystemThe introduction of sugar in the West resulted in the development of the plantation system in Brazil and2 Lecture 34the West Indies. The plantation system, where major crops were both grown and processed for export, was an important innovation in agriculture. Unfortunately, this led to the reinvigoration of slavery, especially black slaves from Africa, resulting in the mass importation of Africans against their will into the New World. The valuable Sugar Islands in the West Indies were to contribute to major confl icts between European pow-ers for control of the Americas.The Portuguese fi rst came to Recife in northeastern Brazil in the 16th century. Large land grants estab-lished plantations along the coast 150 miles wide and as far West as could be controlled. Sugar was familiar to the Portuguese who were cultivating it in the Azores, Madeira, and Capo Verde, islands off the African coast and discovered by the Portuguese in the 15th century. The crop was well suited to the lowland tropical coast of Northeast Brazil but the crop does even better with a drier season, and so, at present, sugarcane has moved to savanna climates (grassland types, summer wet, winter dry) in the South. The largest production is now in Sao Paolo state).By the 3rd decade of the 1500s, sugar was established in Brazil as a result of unlimited land, good climate for production, and unlimited demand in Europe. The chief disadvantage was a lack of labor. The native “Indian” population did not make good slave labor and succumbed to many of the diseases introduced from Europe. The solution was African slaves already used in the sugar industry of Madeira and available from trading stations operated along the West Coast of Africa where the Portuguese had established forts. Sugar became the fi rst plantation crop, based on the European incursion into the Americas (Colonial system). A single crop grown and processed under a single operation, typically managed by Europeans, and, typically, a crop cultivated in the tropics with colonial overtones characterized the plantation. The plantation was a highly capitalized system requiring huge investments for a myriad of products particularly processing machinery. Unlike the feudal system, where lord and vassal had duties and obligations (clearly not sym-metrical), the introduction of slaves made labor a form of property with overriding fi nancial rather than human concerns. Slavery has been present in one form or another for most of human history but
