Future CH4 emissions from rice production

CH4 emissions from rice paddies have been estimated to the year 2025. A model based on current rice production per capita values (1989) for the 94 major rice-producing countries and United Nations population predictions was used to calculate future emission fluxes of CH4. Results show that CH4 emissions from rice paddies are predicted to increase by an average of 1.1% yr−1 from the 1990 level of 97 Tg yr−1 to 145 Tg yr−1 in 2025.
