Downloadable (with restrictions)! Paddy rice cultivation is an important source of global anthropogenic methane emissions. Drainage the flooded soils can reduce methane substantially, but N2O emission occur concurrently, which would offset the reduction of methane emission. It remains unclear how mid-season drainage affects the global warming potential (GWP) of CH4 and N2O emissions.

Calculated CH4 radiative forcing is about 25% higher than earlier estimates New simplified expressions for forcing are presented for CO2, N2O, and CH4 Forcing for high CO2 concentrations is 9% high

•Biochar reduced direct N2O emission factor (EFd), and response of CH4 emissions. • BC amendment is a pragmatic approach in mitigating GWP in boreal climate. Other authors. See publication. Our “best estimate” of net GWP for CO2, CH4 and N2O fluxes was −0.50 ± 0.27 Pg CO2 eq/year (1 Pg = 1015 g) in North American terrestrial ecosystems during 2001–2010.

about half were nitrous oxide and the second half methane. Emissions from warming potential factors (GWP) according to decision 4/CMP.7 and presented in.

The proportion of GWP CO2, GWP CH4 and GWP N2O ’s contribution (%) to net GWP was 13.8 to 26.5, 71.9 to 86.1 and 0.13 to 1.61, respectively. This indicates that CH 4 was a major contributor to GWP in the paddy field and was governed by management practices especially residue and water regimes.

GWP* has been proposed to take better account of short-lived climate pollutants (SLCP) such as methane, relating a change in the rate of emissions of SLCPs to a fixed quantity of CO2. [20] Calculating the global warming potential [ edit ]
