Irrigated rice cultivation plays an important role in affecting atmospheric greenhouse
gas concentrations. In recent years, extrapolation and simulation of impact of farming management
on GHGs fluxes from field studies to a regional scale by models approach has been implementing.
In this study, the DeNitrification & DeComposition (DNDC) model was validated to enhance its
capacity of predicting methane (CH4) emissions from typical irrigated rice-based system in Vu
Gia-Thu Bồn River Basin with two water management practices: Continuous Flooding and
Alternate Wetting-Drying.2 rice field experiments were conducted at delta lowland (Duy Xuyen
district) and midland (Dai Loc di...
