Understanding Natural and Anthropogenic Disturbances in Biogeochemistry and Carbon-water Coupling
Understanding Natural and Anthropogenic Disturbances in Biogeochemistry and Carbon-water Coupling
Session ID#: 122545
Session Description:
Disturbances, including both climate-sensitive natural phenomena (e.g., hurricane, fire or drought) and anthropogenic land use (e.g., deforestation or forest management), result in either transient or persistent changes in the structure and composition of terrestrial ecosystems. These alterations imply modifications in surface flux and stock of carbon, water, energy and nutrient, which directly or indirectly feedback to regional and global biogeochemical cycles and climate. Currently, key knowledge gaps exist for understanding the processes and impacts of disturbances. A plethora of new remote sensing platforms have allowed for the monitoring of these ecosystem properties with unprecedented nuance. Insights from these new datasets have yet to be effectively incorporated into Earth system models. We encourage abstracts that identify key influence factors (e.g., forest age, peatland drainage density) that affect the spatiotemporal pattern of ecosystem disturbances, and that assess the subsequent carbon emissions or water imbalance using field data, remote sensing products, and models.
