This study comprises a set of methane emission measurements in rice fields located in the four agro-ecological zones of the Mekong River Delta (MRD), namely the zones with (i) alluvial soils, (ii) salinity intrusion, (iii) deep flood, and (iv) acid sulfate soils. These zones have very distinct bi...

This study comprises field experiments on methane emissions from rice fields conducted with an Eddy-Covariance (EC) system as well as test runs for a modified closed chamber approach based on measurements at nighttime. The EC data set covers 4 cropping seasons with highly resolved emission rates ...

This is an info note elaborating on a study of the International Rice Research Institute (IRRI) conducted by Vo et al. (2018) on methane emission from rice cultivation in different agro-ecological zones of the Mekong River Delta, focusing on seasonal patterns and emission factors for baseline wat...

Open-burning of rice straw residues pollutes the air and contributes to global warming through emissions of greenhouse gases (GHGs). Although burning of straw residues emits large amounts of CO2, this component of the smoke is not considered as net GHG emissions and only concludes the annual carb...

A comparative experiment of different on-field straw management practices]How does burning of rice straw affect CH4 and N2O emissions? A comparative experiment of different on-field straw management practices

Methane (CH4) is a major greenhouse gas (GHG), which accounts for 16% of the global GHG effect. In the agriculture sector, rice cultivation substantially contributes 10% of all anthropogenic CH4 emissions, thus the importance of determining the variables that influence and/or control CH4 producti...
