Expanding the Critical Zone concept to examine biogeochemistry in Latin America and beyond
Session ID#: 82575
Session Description:
Research with the Critical Zone (CZ) is interdisciplinary and examines biogeochemical processes of the Earth’s surface, spanning the lower atmosphere, vegetation canopies, soils, groundwater, and bedrock. The CZ network includes sites in North America and Europe, but also extends to South America, Africa, Asia, and Oceania. This session aims to showcase international and interdisciplinary biogeochemical CZ research with abstracts that: 1) quantify how changes in land use/cover alter CZ biogeochemistry; 2) examine the ramifications of disturbance on the CZ, including human activities and natural disasters; 3) highlight interactions between CZ biogeochemistry and science-based management like the food-water-energy nexus and soil health; and 4) demonstrate the importance of scaling and modeling within the CZ to inform management. This session provides a platform for interdisciplinary collaboration and idea generation within the CZ community for future international studies to enhance our understanding of the structure and functioning of the human-natural world.
