Research on rice cultivation shows that water saving measures, such as controlling of irrigation, alternation of wetting and drying could effectively reduce the emission of CH4. Ditches constructed in the project area could manage the water in rice paddies, alternating continuous flooding in the field with intermittent flooding. It will lead to less CH4 emissions because the CH4 emissions from the anaerobic decomposition of organic matter under flooded condition of the paddy are lowered.
The ditches was constructed after 2021 or is planned to be constructed in the near future
