Economic botany is the study of the relationship between people (individuals and cultures) and plants. Economic botany intersects many fields including established disciplines such as agronomy, anthropology, archaeology, chemistry, economics, ethnobotany, ethnology, forestry, genetic resources, geography, geology, horticulture, medicine, microbiology, nutrition, pharmacognosy, and pharmacology. This link between botany and anthropology explores the ways humans use plants for food, medicines, and commerce.
History
In a 1958 essay at the conference that founded the Society for Economic Botany, David J. Rogers wrote, "A current viewpoint is that economic botany should concern itself with basic botanical, phytochemical and ethnological studies of plants known to be useful or those which may have potential uses so far underdeveloped. Economic botany is, then, a composite of those sciences working specifically with plants of importance to [people]." Closely allied with economic botany is ethnobotany, which emphasizes plants in the context of anthropology.
Botany itself came about through medicine and the development of herbal remedies. Thus at its advent, botany was economic as well as systematic. As plants became useful for herbals and curatives, their economic value increased. An early set of instructions drawn up by a cosmographer of Charles the fifth instructed explorers to "determine what are the items of sustenance of the land and which ones are generally used, whether fruits or seeds, and all manner of spices, drugs, or whatever other scents, and find out the time in which one can reproduce the trees, plants, herbs, and fruits that these parts offer, and if the natives use them for medicines, as we do." Teosinte and rice are two examples of plants modified so that their economic values would increase.
Economic botany in colonial Spain
Contrary to common belief that modern economic botany had been spearheaded by the British as early as the 19th century, economic botany had been exemplified in the form of plant diffusion for millennia. It really took a foothold beginning as early as the 7th century during the early phases of the Islamic Empire. Then it was further studied by the Spanish due to their lack of economic power in the spice trade of colonial world.
Roots in Islamic endeavors
As the Islamic Empire reached its westernmost limits on the Iberian Peninsula, Muslims were able to bring with them flora from the east. Between the 10th and 11th centuries, multiple types of non-native citrus were reported to exist on the Iberian Peninsula. Several books were published on the subject between the 10th and 14th centuries, showing the detailed nature of Islamic botany, differentiating between various citrus such as lemons, limes, sweet and sour oranges, pomelos, and grapefruit. In addition to classifying these various citrus before western naturalists, the Muslims were also responsible for citrus diffusion (except for the citron) and cultivation in the Mediterranean Basin. Because of Islamic presence in the Iberian Peninsula before the fall of the Empire, Paula De Vos explained that the greater western world gained its botanical scientific roots from Islamic botany.
Early Spanish botany
Spanish exploration for spices
During the Age of Exploration and Discovery, the Spanish engaged in botany not for the sake of botany as a science, but for economic and personal gain. The Spanish King Charles III stated that an expedition to South America in the 18th century was for the benefit of learning about the regions' flora, but more specifically to build upon the kings' Museum and Garden with plants and botanical illustrations. For the most part, many of these expeditions from Spain were taxonomic, but the botanists did take note of medicinal uses of many flora.
The other factor for Spanish involvement in botanical sciences during this time was because of their lack of power in spice trade. The main location for spice trade during this time was in the Spice Islands, which had been under the control of the Portuguese since 1513 until later in the 17 century when it was taken over by the Dutch. The Spanish Empire sent Magellan on a voyage for the purpose of gaining trade relations with the Spice Islands, but failed due to Portuguese control of the area. Spanish attempts at gaining power in the Spice Islands, however, were not fruitless. Antonio Pigafetta, who was on Magellan's expedition recorded many important botanical properties of the important spices found in the Maluku Islands, which would later help the Spanish in their botanical economically motivated botanical pursuits.
