Yungas

Yungas

Yungas, tropical river valleys of Bolivia that spread northeast to southeast beyond the temperate valleys of the eastern Andean slopes. Here, Amazon winds maintained the humidity necessary for the cultivation of crops not available in the highlands. The pre-Inca Aymara empire sustained its highland centers by sending Mitmaes (colonists) down to the yungas to cultivate fruits, maize, and, for highland elite consumption, the stimulant coca. In return, the highlands sent items not produced in the tropical zones, such as meat, potatoes, quinoa, and wool, thus fulfilling their obligations in this Andean system of reciprocity.

With the Spanish conquest and subsequent discovery of silver, coca use changed dramatically and was no longer confined to the native elite. Coca consumption now enabled Andeans to endure harsh mining activities for protracted periods of time. Production in Cuzco could not meet the increased demand, and the yungas of La Paz became a major coca zone. Not only did Aymara agricultural migrants continue to replace the nomadic peoples of the region, merchants imported African slaves, who by the early nineteenth century had become a viable Aymara-speaking subgroup in this region. La Paz and its neighboring yungas now thrived while other regions experienced economic decline.

Other less accessible yungas existed in the provinces of Cochabamba and Santa Cruz. The Chaparé region, northeast of Cochabamba, formerly controlled by the Yuracarés, today produces prodigious amounts of coca. In the colonial period, La Paz merchants intervened and prevented Chaparé competition. The yungas of Pocona, which was first settled in 1538 and incorporated into the jurisdiction of Mizque before the end of the century, were mass-producing coca by 1557.

Even today, the fertile yungas and Oriente regions remain largely underdeveloped despite their year-round growing season. Poor infrastructure, disease (human and plant), pests, floods, and soil erosion discourage serious agricultural activity.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
