英文摘要	Fisheries capture has plateaued, creating ever-greater reliance on aquaculture to feed growing populations. Aquaculture volumes now exceed those of capture fisheries globally 1,2 , with China dominating production through major land-use change; more than half of Chinese freshwater aquaculture systems have been converted from paddy fields 1,3 . However, the greenhouse gas implications of this expansion have yet to be effectively quantified. Here, we measure year-round methane (CH 4 ), nitrous oxide (N 2 O) and carbon dioxide (CO 2 ) emissions from paddy fields and new, extensively managed crab aquaculture ponds. The conversion increased associated global warming potentials from 8.15 ± 0.43 to 28.0 ± 4.1 MgCO 2 eq ha −1 , primarily due to increased CH 4 emissions. After compiling a worldwide database of different freshwater aquaculture systems, the top 21 producers were estimated to release 6.04 ± 1.17 TgCH 4 and 36.7 ± 6.1 GgN 2 O in 2014. We found that 80.3% of the total CH 4 emitted originated in shallow earthen aquaculture systems, with far lower emissions from intensified systems with continuous aeration 4 . We therefore propose that greater adoption of aerated systems is urgently required to address globally significant rises in CH 4 emissions from the conversion of paddy fields to aquaculture. © 2019, The Author(s), under exclusive licence to Springer Nature Limited.
