Abstract Inland waters are significant emitters of greenhouse gases for the atmosphere and play an important role in global carbon cycle. With a vast land area East Asia spanning broad range climatic conditions, China has large number natural human‐made water bodies. These inland systems importance because their high emission fluxes. Over past decades, experienced unprecedented environmental changes driven by rapid economic development, which have profoundly modified its biogeochemistry associated emissions. This review focuses on dioxide (CO 2 ) methane (CH 4 dynamics from China's response to change. Major drivers CO CH emissions, including aquatic metabolism, hydrological factors, prevailing human impacts, examined. To advance our understanding emissions waters, we further identify several critical knowledge gaps, such as inadequate research headwater streams climate‐sensitive Tibetan Plateau ecosystems. Furthermore, insufficient undergoing extensive interventions (e.g., damming, flow regulation, pollution, farming practices aquaculture ponds) is highlighted. We suggest that future efforts should be made better capture spatiotemporal heterogeneity dissolved concentrations fluxes across well long‐term trends. overcome uncertainties sources current flux estimates, mechanistically understand transport transformation Chinese underlying processes particularly needed.

Abstract Tidal wetland reclamation is a worldwide issue that profoundly alters ecological functions and ecosystem service provisions; however, its impacts on sediment microbial communities remain poorly understood. Here, we investigated the spatial seasonal patterns of greenhouse gas (GHG) production in response to land use change mangrove wetlands elucidated underlying mechanisms by integrating environmental parameters community characteristics. In time period studied, substantially reduced organic matter content, richness diversity, CO 2 rates. Converting mangroves drier cover types, namely orchard vegetable field, significantly diminished reducing substrates (sulfide, Fe 2+ , NH 4 + ), network complexity stability, CH rates, while increasing N O contrast, these showed opposite trend following conversion flooded aquaculture pond. Overall GHG rate was 399.8 mg e kg −1 d which respectively decreased 68.83%, 69.86%, 30.84% orchard, Microbial stability were strongly related rates O, rather than can be better indicators specialized (CH production). Therefore, preserving “interaction” could important mitigate negative effects diversity loss caused human activities aquatic environments. Future research should consider conditions composition, interactions, gain comprehensive understanding functions.

Abstract East Asia (China, Japan, Koreas, and Mongolia) has been the world's economic engine over at least past two decades, exhibiting a rapid increase in fossil fuel emissions of greenhouse gases (GHGs) expressed recent ambition to achieve climate neutrality by mid‐century. However, GHG balance its terrestrial ecosystems remains poorly constrained. Here, we present synthesis three most important long‐lived (CO 2 , CH 4 N O) budgets during decades 2000s 2010s, following dual constraint approach. We estimate that is close GHGs, with magnitude between −46.3 ± 505.9 Tg CO eq yr −1 (the top‐down approach) −36.1 207.1 bottom‐up 2000–2019. This net sink includes large land (−1229.3 430.9 based on approach −1353.8 158.5 being offset biogenic O emissions, predominantly coming from agricultural sectors. Emerging data sources modeling capacities have helped agreement approaches, but sizable uncertainties remain several flux terms. For example, reported use cover change varies source more than 300 ∼−700 . Although neutral currently, curbing additional afforestation forest managements potential transform into sink, which would help realizing Asian countries' ambitions neutrality.
