Rice production is integral to agriculture and food security in Vietnam, but it also contributes greenhouse gas emissions. In 2010, paddy rice production emitted 44.61 million tons carbon dioxide equivalents (MtCO2e), 18% of total national GHG emissions. A variety of options to mitigate GHG emiss...

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...

Paddy soil drainage influences residue carbon contribution to methane emissions
Rice production systems are an important source of agricultural greenhouse gas (GHG) emissions. Mitigation techniques, such as alternate wetting and drying, have been developed but have often not taken into consideration the constraints imposed by the practices and preferences of farmers. Since G...

Co-design and assessment of mitigation practices in rice production systems: A case study in northern Vietnam
Irrigated rice cultivation is a major source of greenhouse gas (GHG) emissions from agriculture. Methane (CH4) and nitrous oxide (N2O) are emitted not only throughout the growing season but also in the fallow period between crops. A study was conducted for two transition periods between rice crop...

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...

Rice production is a major source of global methane emissions and many studies have been conducted to quantify flux rates of methane alongside N2O emissions from rice fields. The closed chamber method with manual sampling is the conventional approach for determining greenhouse gas (GHG) emission ...

70% of the world’s freshwater is used for irrigated agriculture and demand is expected to increase to meet future food security requirements. In Asia, rice accounts for the largest proportion of irrigated water use and reducing or conserving water in rice systems has been a long standing goal in ...

Rice fields in the tropics can vary in water regime before production of rice on flooded soil, but relatively little is known about the effects of soil water regime and crop residue management between rice crops (i.e., fallow period) on methane (CH4) and nitrous oxide (N2O) emissions during a sub...

This paper presents the results of key informant interviews conducted in Tra Hat Climate-Smart Village (CSV) in Vietnam. The interviews aimed to further assess the climate-smart agriculture (CSA) practices that farmers wanted to adopt on their farms, as well as the factors and barriers for adopti...
