The basin of the Amazon River is delimited from the watershed and comprises the surface occupied by the river and its thousands of tributaries, covering an area of 7,352,122 km2, in six countries: Bolivia, Brazil, Colombia, Ecuador, Peru And Venezuela. Considering this criterion, the concept of Amazon includes the Andean territories and inhabitants of all the countries that share it, involving the Amazonian inhabitants, not only of the plains, but of all the Andean thermal floors: temperate, cold and moorland and some snow capped territories (Dominguez, 1987).
