“…Significant increase in CO 2 emissions were observed mostly in rice paddy studies when continuous flooding was compared with intermittent drainage or flooding. In a study by Haque et al [71], the average CO 2 emissions were significantly increased by 47% in a mid-season drainage treatment compared to continuous flooding. A similar increase (19%) in CO 2 emissions was reported by Haque et al [72] in another study when they compared continuous flooding and intermittent drainage.…”

“…For example, increase in N 2 O emissions (up to 4.5 kg N 2 O ha −1 ) was observed in studies that applied intermittent irrigation as compared to traditional irrigation or continuous flooding [65,72,77,83,[86][87][88]91]. Similarly, a number of studies demonstrated that continuous flooding leads to lower N 2 O emissions as compared to water-saving irrigation treatments in studies done in China, South Korea, and the USA [57,64,71,76,84,85].…”

“…In relation to continuous flooding irrigation, the intermittent irrigation reduced seasonal CH 4 emissions by 47%, and increased N 2 O emissions by 876% in the Brazil paddy fields [35]. Midseason drainage significantly reduced seasonal CH 4 fluxes of paddy fields in South Korea by 50-53%, but significantly increased N 2 O flux by 20-37% over conventional flooding [36]. Irrigation techniques had no significant effect on GHG regulation due to the main part of GHGs in this study being to uptake CO 2 .…”

“…In the modern agricultural industry, rice yields and environmental impacts have to be evaluated simultaneously when determining the appropriate soil management strategy [13]. More environmentally friendly agricultural systems are being explored that results in higher rice productivity for food security and with lower net GWP and GHGI [14]. For example, the presence of frogs, ducks, and fish can reduce the occurrence of diseases, pests, and weeds in rice fields [15,16].…”
