Amazon Basins
Occupying more than 6.8 million km2, the Amazon is the largest river basin in the world and nearly twice the size of that of the Congo, the second largest. Although some do not consider the Tocantins Basin to be part of the Amazon Basin it is nevertheless connected geographically and ecologically to it and its lower course is invaded by Amazon River water.
Pan-Amazon Basins
The new Pan-Amazon basins classification (Eduardo Venticinque, Bruce Forsberg, Ronaldo Barthem, and Michael Goulding, 2021) addresses the challenge of conservation at scale, and offers a useful spatial reduction to make integrated analysis of the aquatic, semi-aquatic and land systems at the Amazon Biome scale, or at different hydrographic scales.
