• If CH₄ emissions from rice cultivation are identified as a key category, whether country-specific seasonally-integrated emission factors for each region and scaling factors for water management, organic amendments, and soil type have been developed and used.
• If country-specific activity data on harvested areas were not available, whether relevant such data from international agencies (i.e., International Rice Research Institute, FAO) have been collected;
• Whether the emission estimates reflect multiple cropping rotations occurring in a given year on the same piece of land (i.e., ratoon crops).
