Abstract Land‐use/land‐cover change (LULCC) often results in degradation of natural wetlands and affects the dynamics greenhouse gases (GHGs). However, magnitude changes GHG emissions from undergoing various LULCC types remains unclear. We conducted a global meta‐analysis with database 209 sites to examine effects constructed (CWs), croplands (CLs), aquaculture ponds (APs), drained (DWs), pastures (PASs) on variability CO 2 , CH 4 N O coastal wetlands, riparian peatlands. Our showed that were net sinks atmospheric sources O, exhibiting capacity mitigate due negative comprehensive warming potentials (GWPs; −0.9 −8.7 t ‐eq ha −1 year ). Relative all (except CWs wetlands) decreased uptake by 69.7%−456.6%, higher increase ecosystem respiration relative slight gross primary production. The APs significantly increased compared those wetlands. All associated emissions. When peatlands converted PASs, increased. CLs, as well DWs peatlands, As result, PASs led remarkably GWPs 65.4%−2,948.8%, fluxes was mainly sensitive soil water content, table, salinity, nitrogen pH, bulk density. This study highlights significant role increasing our are useful for improving future models manipulative experiments.
