Estimates of the grassland fluxes of CO2, CH4 and N2O for the last five decades from ORCHIDEE-GM were evaluated against site observations, and regional GHG inventories (Supplementary Discussion 1 and Supplementary Table 2). We also compared our simulated GHG budgets with estimates from … See more The GHG balance of grasslands presented in the previous section contains pre-industrial fluxes and perturbations by human activities including both direct effects from land use and management changes and indirect … See more Globally, the positive RF from managed grasslands, including emissions from land-use change related to grasslands, equals 205 ± 48 mW m−2 (Fig. 4a). This management-induced RF counter-balances the … See more WebUsing a process-based biogeochemical model, we predicted that low levels of Ndep either enhanced or reduced the net GHG sink strength of most grasslands, but as experimental N loads continued to increase, grasslands transitioned to a N saturation-decline stage, where the sensitivity of GHG exchange to further increases in Ndep declined.
