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...

Climate-smart Agriculture (CSA) represents a commonly accepted term in referring to intended changes in agriculture production addressing climate change. Although specific definitions may vary, CSA is typically conceived as having three pillars, namely Adaptation, Food Security and Mitigation. Th...

Global rice production systems face two opposing challenges: the need to increase production to accommodate the world's growing population while simultaneously reducing greenhouse gas (GHG) emissions. Adaptations to drainage regimes are one of the most promising options for methane mitigation in ...

Rice agriculture is a large anthropogenic source of atmospheric methane (CH 4 ). The reliable estimation of CH 4 emissions requires frequent measurements to trace diurnal and seasonal variations. To evaluate the appropriate intervals and optimal time of day to measure CH 4 emissions using t...

Greenhouse gas (GHG) mitigation strategies are often constrained by rice farmers’ preferences, therefore an assessment of mitigation strategies taking farmers’ constraints into consideration, are important for their pos- sible adoption. The field experiments were conducted for two continuous rice...

Reducing greenhouse gas (GHG) emissions from agriculture is needed to meet global climate policy targets. A number of low-emission development (LED) options exist in agriculture, which globally emits 10–12% of GHG emissions. In paddy rice production, alternative wetting and drying (AWD) can reduc...

Elevated greenhouse gas (GHG) emissions, particularly of methane (CH4) from flooded rice production systems contribute to global warming. Different crop management strategies, such as drainage of paddy soils and climate-smart residue management, are essential in order to mitigate GHG emissions fr...

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 study unravels the implications of outmigration for farm labour availability, managerial feminization, women’s agency, and farm production. Findings suggest that migration contributes to increased off-farm income, with higher income from international migration. While men’s labour contributi...

Water drainage is an important mitigation option for reducing CH4 (methane) emissions from residue-amended paddy soils. Several studies have indicated a long-term reduction in CH4 emissions, even after re-flooding, suggesting that the mechanism goes beyond creating temporary oxidized conditions i...
