Traditional flooded rice cultivation in Vietnam ensures stable yields but consumes tens of billions of cubic meters of water and emits tens of millions of tons of methane (CH₄) annually. As Vietnam commits to achieving net-zero emissions by 2050, the research and application of the Alternate Wetting and Drying (AWD) irrigation technique have opened a new pathway, reducing irrigation water use by 20-50% and cutting greenhouse gas emissions by nearly half.
