Herrera Sarmiento E. - Editorial INIA, Cochabamba, Bolivia, 2015
The indigenous Ese Ejja have been studied by explorers and anthropologists since the early 19th Century. These people are traditionally associated with riparian hábitats and floodplains in the basins of the Rivers Madidi, Beni and Madre de Dios, and are considered generally as fishermen. The objective of Herrera Sarmiento with writing the book was to understand the perception fishermen have of their main activitiy. The study was conducted in Portachuelo Bajo, in TCO TIM II. The book shows that fishing is very important for family subsistence and the principal economic activity. The autor also suggests that the nomadic lifecycle has largely been replaced by sendentarism, which has greatly influenced their resource use.
