Response of eutrophication and water quality drivers on greenhouse gas emissions in lakes of China: A critical analysis

Abstract: Lakes, especially shallow lakes, contribute disproportionately to greenhouse gas (GHG; particularly CO2 and CH4) emissions and have received global attention due to their high potential to contribute to global warming and future climate change. Recent studies have identified eutrophication as a critical factor in GHG emissions. However, the role of lake trophic state index (TSI) and the impact of important water quality parameters (WQP) such as pH, Chl‐a, total nitrogen, total phosphorus and organic carbon on … Show more

“…A recent global meta-analysis found that natural wetlands were "net sinks of atmospheric CO 2 and net sources of CH 4 and N 2 O, exhibiting the capacity to mitigate greenhouse effects due to negative comprehensive global warming potentials (GWPs; -.9 to -8.7 t CO 2 -eq ha −1 year −1 )" (Tan et al, 2020). This analysis and other studies further highlight that the spatio-temporal variability in GHG emission is primarily sensitive to changes in water temperature, surface water content, chlorophyll-a, soil nitrogen content, bulk density, and soil pH (Kumar et al, 2022;Liu et al;Malyan et al, 2022;Zhou et al, 2022).…”

“…However, P retention by reservoirs does not always result in a reduction in P export from the watershed. Instead, exports may increase because of the significant influence of anthropogenic P sources (Kumar et al, 2022). Moreover, exogenous input changes the proportion of nutrients available in different forms.…”

“…In recent decades, excessive amounts of nutrients (nitrogen and phosphorous) discharged, either directly or indirectly, into freshwater bodies (e.g., rivers and lakes), leading to severe eutrophication (Ho et al, 2019; Kumar et al, 2023). When the lake is already in a state of eutrophication, the nutrient concentration no longer limits the growth of algae and the formation of algal blooms (Huang et al, 2020).…”

“…The outbreak of algal blooms in Taihu Lake is associated with various environmental factors such as meteorological conditions, nutrient concentration and hydrological conditions (Khan et al, 2016; Liao et al, 2021). Therefore, scientific identification of key driving factors is of great significance for exploring the mechanism of cyanobacterial blooms, which will further help to formulate sustainable lake protection and management measures to ensure that the ecological functions and economic value of Taihu Lake can be maintained for a long time (Kumar et al, 2023).…”
