The Napo is a tributary to the Amazon River that rises in Ecuador on the flanks of the volcanoes of Antisana, Sincholagua and Cotopaxi.
From the north it is joined by the riverCoca, having its sources in the gorges of Cayambe (volcano) on the equator, and also a powerful river, the Aguarico, having its headwaters between Cayambe and the Colombian frontier.
The illicit coca crop, however, is produced mainly by large-scale industrial growers -- often immigrants from cities -- who tend to ignore traditional planting methods (such as the use of terracing) and, in their quest for profits, cause severe environmental damage in virgin growing regions newly opened to meet the demands of foreign markets.
According to one Peruvian conservationist, coca leaf was the largest cultivated crop in the Peruvian Amazon in the 1980s and accounted for a significant percentage of total deforestation there in the 1970s and 1980s.
In the first phase of converting raw coca leaves to coca paste, usually done near the site of the coca cultivation, the leaves are placed in a container or plastic-lined pit to which a strong acid (such as sulfuric acid) and water are added.
