Simulation of Water Saving and Methane Mitigation Potential of Paddy Fields under Alternate Wetting and Drying Irrigation Regime in China

Paddy fields are the main consumption of agricultural water and the main source of greenhouse gas methane (CH4). Water use in paddy fields accounts for about 70% of agricultural water worldwide. 9%-19% of CH4 in the atmosphere comes from rice season around global. As the largest rice producer, China’s rice planting area and production account for more than 23% and 30% of the ...
