English: Abstract The resilience of the Amazon rainforest to climate and land-use change is crucial for biodiversity, regional climate and the global carbon cycle. Deforestation and climate change, via increasing dry-season length and drought frequency, may already have pushed the Amazon close to a critical threshold of rainforest dieback.
The Amazon rainforest, [a] also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km 2 (2,700,000 sq mi), [ 2 ] of which 6,000,000 km 2 (2,300,000 sq mi) are covered by the rainforest . [ 3 ]
The Amazon biome has an area of 6,700,000 square kilometres (2,600,000 sq mi). [2] [a] The biome roughly corresponds to the Amazon basin, but excludes areas of the Andes to the west and cerrado (savannah) to the south, and includes lands to the northeast extending to the Atlantic ocean with similar vegetation to the Amazon basin.

Since tropical rainforests are estimated to hold 50% of the planet's species, the canopy of rainforests worldwide may hold 45% of life on Earth. The Amazon rainforest borders eight countries, and has the world's largest river basin and is the source of 1/5 of the Earth's river water. It has the world's greatest diversity of birds and freshwater ...

95% of the deforestation in the Amazon Rainforest "happens within 3.4 miles of a roadway". Forest clearing always begins near new roads, after expands further. In December 2023 the lower house of the Brazilian Congress approved a bill aiming to pave again the high way BR-319 (Brazil highway), what can threaten the existence of the rainforest.
The northern limit begins with the Guaviare and Vichada Rivers and extends south to the Putumayo and Amazon Rivers. The Amazon region is divided up into distinct subregions: Amazon foothills: bordering the East Andes; Caquetá River Plain: the main watershed of this region; Inírida River Plain: location of the famous Cerros de Mavecure
