B52C:
Land Management in the Earth System: Measurements and Models I

Submit an Abstract to this Session



Session ID#: 35317

Session Description:
Recent estimates suggest that 80% of the ice-free land surface is actively being managed by humans. Land management decisions, including harvest strategies, species selection, fertilization, irrigation, tillage regimes, and fire management, among others, can have a strong influence on local biogeochemical cycles and feedbacks to climate. Earth System Models are increasingly being used to simulate the impact of land management decisions on large-scale ecosystem services. Nonetheless, key data gaps and process unknowns remain that hamper accurate simulation and forecasting.

In this session, we will examine the role of land management decisions in the Earth system. We invite submissions from researchers using observational, experimental, and modeling approaches to explore critical feedbacks between land management, biogeochemical cycles, and climate, from local to global scales. We also welcome submissions from studies examining Earth system feedbacks and teleconnections resulting from land management.
