Ecosystem‐Scale Carbon Dioxide, Methane and Water Vapor Fluxes From Subtropical Brackish Fishponds: Temporal Variability, Environmental Drivers, and Implications for Nature‐Based Climate Solutions

Earth's Future, Volume 13, Issue 5, May 2025.
Abstract Coastal wetlands such as mangroves have a great potential in sequestering blue carbon and mitigating future climate change. Yet, these wetlands are being increasingly converted to aquaculture ponds, which could trigger a pulse emission of greenhouse gases (GHGs) from existing carbon stocks, a loss of opportunity for future carbon sequestration
