B22A:
Multiscale Measurements and Modeling of Greenhouse Gas (CO2, CH4, and N2O) Emissions from Livestock, Grasslands, and Croplands II

Submit an Abstract to this Session



Session ID#: 31977

Session Description:
Emissions of greenhouse gases (CO2, CH4 and N2O) from livestock, grasslands and croplands are affected by multi-scale factors ranging from microbes in the soils to human management practices in agricultural and livestock production systems. Significant progress has been made in multi-scale measurements and modeling of GHG fluxes across the scales of microbe, plot (stationary soil chambers, automated soil chambers), and ecosystems/landscapes (eddy flux tower systems), as well as individual livestock. This session welcomes diverse presentations that report (1) multi-scale measurements of GHG emissions, (2) development of multi-scale models of GHG emissions, including the role of microbes in GHG dynamics, and (3) data-model integration and model simulations across the geographical scales from individual animals or plots, field, farm, landscape, watersheds, to nations and the globe.
