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...

This volume provides relevant information on the Philippine climate change policy response strategy in agriculture, with focus on local implementation of climate change policies. Specifically, it describes the local institutional setting for climate change policy implementation in agriculture, th...

The ‘alternate wetting and drying’ (AWD) technology for rice is a water-saving technology with a high greenhouse gas (GHG) mitigation potential. The Philippine government attempts to disseminate AWD in all national irrigation systems in order to adapt to increasingly scarce water resources. This...

The new GHG calculator named SECTOR (Source-selective and Emission-adjusted GHG CalculaTOR for Cropland) is based on the IPCC Tier 2 approach for rice as well as other crops. The new features of SECTOR facilitate high flexibility in terms of entering newly obtained emission factors, easy data tra...
