Overview of the Research Project

Development of a water management system to reduce methane emissions from rice paddies over a large area

In the Asia-Monsoon region, which includes Cambodia, methane emitted from rice paddies is a major source of greenhouse gas (GHG) emissions. It is known that methane emissions from paddy fields can be reduced by introducing intermittent irrigation, such as alternate wetting and drying (AWD), but little verification has been conducted over large areas of paddy fields. This project will develop and socially implement a large area water management method that reduces methane emissions without reducing rice paddy yields, and a method for monitoring and evaluating GHG reductions.

Establishment of efficient water management, MRV, and methods to create incentives for farmers

The project will develop efficient water management methods from the watershed to the field level to implement intermittent irrigation over a large area, methods to measure, report, and verify (MRV) reductions in methane emissions, and methods to create incentives for farmers by utilizing carbon credits such as the Joint Crediting Mechanism (JCM) promoted by the Japanese government.
