Intact Amazon forest – a natural laboratory of global significance 

The Amazon forest is the world’s largest intact forest landscape. Due to its large biodiversity, carbon storage capacity, and role in the hydrological cycle, it is an extraordinary interdisciplinary natural laboratory of global significance. In the Amazon rain forest biome, it is possible to study atmospheric composition and processes, biogeochemical cycling and energy fluxes at the geo-, bio-, atmosphere interface under near-pristine conditions for a part of the year, and under anthropogenic disturbance of varying intensity the rest of the year. Understanding its current functioning at process up to biome level is elemental for predicting its response upon changing climate and land use, and the impact this will have on global scale.

This session aims at bringing together scientists who investigate the functioning of the Amazon and comparable intact forest landscapes across spatial and temporal scales by means of remote and in-situ observational, modeling, and theoretical studies. Particularly welcome are also presentations of novel, interdisciplinary approaches and techniques that bear the potential of paving the way for a paradigm shift.
