“…These wetlandsprovide favourable habitats for various aquatic organisms like shes, plankton, benthos, macrophytes,etc. (Karnatak et al, 2022) besides several other ecological services and work as a carbon sink (Nag et al, 2023). Wetlands are very diverse and productive waterbodies,providing many shermen with numerous goods, ecological services, and livelihood security (MEA 2005).The water body gives several important commercial shes a safe feeding, breeding, and spawning ground (Jhingran and Pullin, 1985).…”

Wetlands provide numerous ecological services and are key habitats for aquatic flora and fauna. In the Beledanga wetland, the current study was conducted for three years, from July 2019 to June 2021, to evaluate the seasonal influence of physico-chemical parameters on phytoplankton diversity and abundance patterns. Overall 48 phytoplankton taxa were observed. Group Bacillariophyceae (27%) contributed the maximum to the total phytoplankton density. The total abundance of phytoplankton was found utmost during monsoon (4.081×103 unit l-1 ) and least during post-monsoon (3.316×103 unit l-1). One-way ANOVA indicated significant seasonal differences (p<0.05) for some genera. The study gave the idea about the most influencing physic-chemical parameters (DO, turbidity, total hardness, Ca2+, and nitrate) on the growth of phytoplankton with the help of different multivariate and univariate analysis (Canonical correspondence analysis, Karl Pearson’s correlation). The study again highlighted that climate parameters (temperature and rainfall) had some effect on the phytoplanktonic groups. Our study conceded that N: P in the studied wetland was less than the Redfield ratio (16:1) in all three seasons,while the Si:P ratio was noticed in the high range (15:1) during pre-monsoon. The value of theShannon diversity index and Margalef’s species richness index were noticed to be > 3, which signified quite rich in phytoplankton diversity and less pollution in the ecosystem. The algal pollution index was predominant during all the seasons, indicating a high organic load which might be due to seasonal jute retting and intensification of agricultural farming.

“…The relatively high net primary production of emergent macrophytes makes them important players in biogeochemical cycles, contributing to pond ecosystem services in terms of nutrient retention and carbon sequestration [6]. For the wetlands in India, carbon sequestration potential was found to be positively correlated with the proportion of reed areas [7]. The high nitrogen and phosphorus uptake capacity of reed beds is often used to treat nutrient-rich aquaculture effluent [8].…”

In the EU, aquaculture ponds cover an area of 360,000 ha and are a crucial part of the rural landscape. As many ecosystem services (e.g., habitats for protected wildlife, nutrient cycling, etc.) are correlated with the proportion of reed beds relative to open-water areas, it is important in environmental studies to be able to accurately estimate the extent and the temporal dynamics of reed cover. Here, we propose a method for mapping reed cover in fish ponds from freely available Sentinel-2 imagery using the normalized difference vegetation index (NDVI), which we applied to Hungary, the third largest carp producer in the EU. The dynamics of reed cover in Hungarian fish ponds mapped using satellite imagery show a high degree of agreement with the ground-truth points, and when compared with data reported in the annual aquaculture reports for Hungary, it was found that the calculation of reed cover based on the NDVI-based approach was more consistent than the estimates provided in the report. We discuss possible applications of this remote sensing technique in estimating reed-like vegetation cover in fish ponds and the possible use of the results for climate change studies and ecosystem services assessment.

Lake wetlands play a crucial role in mitigating climate change. Human activities and climate change impact the carbon sequestration capacity of lake wetlands. However, this process is intricate. Clarifying the decisive factors that affect carbon sequestration is crucial for preserving, utilizing, and enhancing the carbon sequestration capacity of plateau lake wetlands. Here we analyzed the regulatory role of land use under policy guidance on the carbon sequestration capacity of the plateau lake wetland of Caohai (CHLW), SW China. The results show that: (1) The cumulative carbon sequestration varied significantly from 1990 to 2020, with the highest carbon sequestration of 15.80 × 105 t C in 1995 and the lowest of 3.18 × 105 t C in 2020, mainly originating from endogenous carbon sequestration within the plateau lake wetlands. (2) As of 2020, the carbon stock of CHLW was approximately 2.54 × 108 t C. (3) The carbon sequestration in CHLW experienced a dynamic change process of decrease-increase-decrease over 30 years, mainly influenced by land use changes under policy regulation, with human and natural factors accounting for 91% and 9%, respectively. (4) Under three simulated scenarios (Q1, Q2, and Q3), the ecological priority scenario exhibited positive regulation on the carbon sequestration of CHLW and the entire protected area in 2030 and 2060, with the highest increase in carbon sequestration. This scenario is consistent with the current conservation policy, indicating that the current protection policy for CHLW is scientifically reasonable. This research demonstrates how land use and climate changes impact carbon storage in wetlands, with consideration of policy guidance. It provides references for utilizing and conserving lake wetlands worldwide, ultimately achieving the dual goals of wetland conservation and carbon neutrality.
