Climate and Human-driven impacts on Amazonian Forests

Session ID#: 161856

Session Description:
The Amazon region has the largest and diverse rainforest in the world. However, intensifying anthropic pressure and associated land cover changes have led to large-scale forest loss. The Amazon rainforest influences the terrestrial climate system through exchanges of energy, carbon dioxide, and water between earth’s surface and atmosphere. In addition to providing water vapor to the environment through evapotranspiration, influencing general circulation in the tropics and contributing to regional precipitation, the Amazon rainforest plays an important role in the global carbon cycle.

Deforestation processes and increases in temperature and reduction in precipitation associated with climate change are triggering forest degradation, with parts of the forest already becoming a carbon source. The increase in climate extremes is also impacting the forest in several ways. Recent results also show that the forest is losing resilience. In order to understand the complex interactions between forest-climate-extremes, it is necessary to focus on different processes that also affect biodiversity loss and ecosystem services.

Topics of interest include but are not limited to: new satellite data and tools to assess deforestation, forest fragmentation and natural recovery; belowground biogeochemistry, plant demography and ecophysiology, plant functional traits, aquifer-to-canopy hydrology; forest-atmosphere interactions; impacts of severe events such as droughts and fire; tolerance and resilience of the Amazon rainforest to extreme events, taking into consideration the drivers of land degradation and deforestation and further transitions under a climate change scenario.
