Session Proposal: Anthropocene Changes in Tropical Forests (AGU25)

B015
Anthropocene Changes in Tropical Forests

Session ID#: 250525

Session Description:
Tropical forests are undergoing rapid transformations driven by increasing anthropogenic pressures, climate change, and land use change. In Amazonia, some regions are transitioning from carbon sinks to carbon sources. This session expands the focus to tropical forests globally—including the Amazon, Congo Basin, and Southeast Asia—which harbor the planet’s richest biodiversity and largest carbon stocks. Forest-atmosphere interactions, resilience thresholds, and ecosystem services are being reshaped by rising temperatures, shifting precipitation, and more frequent extreme events. These disturbances accelerate forest loss and fragmentation, eroding resilience and altering biophysical feedbacks from local to global scales. We invite contributions exploring how land use and land cover change (LULCC)—including deforestation, degradation, fire, conversion, and restoration—are altering forest structure and function. Emphasis is on impacts to water, carbon, and energy stocks and fluxes. We welcome research using remote sensing (e.g., MODIS, ECOSTRESS, SMAP, GEDI, Sentinel), in situ data (e.g., flux towers, plant traits), and modeling approaches.
