– Statement 2 (Reduced methane production): Methane is produced in rice paddies under continuous flooding due to anaerobic decomposition. Alternate wetting and drying cycles introduce oxygen into the soil, reducing anaerobic conditions and thus significantly lowering methane emissions. Correct.
– Statement 3 (Reduced electricity consumption): Less water is used in SRI due to AWD compared to continuous flooding. If irrigation relies on electric pumps, reduced water usage translates directly to reduced electricity consumption for pumping. Correct.
