“…Higher values of EC at some depths of the sediment core are attributed to the high concentration of ions released from the decomposition and mineralization of domestic wastes and OM. The Anchar Wetland receives large quantities of inorganic and organic wastes in the form of raw fecal matter, domestic sewage, animal wastes from the catchment areas having a high concentration of dissolved materials (Dar et al, 2021c). The low values of EC at some depths may be attributed to the low concentration of exchangeable ions.…”

A better understanding of the organic matter (OM) dynamics is a key to successful wetland management. We established the radiocarbon chronology (14C) and vertical distribution of nitrogen (N), phosphorus (P), OM, and carbon to nitrogen ratio (C/N) in the sediment core retrieved from the Anchar Wetland, Kashmir Himalaya. The accelerator mass spectrometer (AMS) assisted 14C dating of the sediment core showed 14C age reversals related to occasional disturbances. The vertical distribution of various fractions revealed increased concentrations of organic carbon (OC), OM, and nutrients (N and P) in the upper part of the sediment core, largely related to increased anthropogenic inputs from the catchment areas during recent decades. Further, the low to high C/N ratio (1.3–36.4) suggests a combination of both the autochthonous and allochthonous inputs as the major contributors of OM to the wetland ecosystem. The linear regression model showed significant (p < 0.05) positive and negative relationships among various analyzed parameters. Principal component analysis (PCA) resulted in three principal components (PCs) accounting for a cumulative variance of 83.6%. The PCA suggests that the primary production, human activities such as extraction of Lotus stems (Nadru) and fishing, and terrestrial inputs (sewage disposal and fertilizer runoff) are the major factors controlling the distribution of organic fractions and nutrients. This study provides important insights into the sources and distribution of sedimentary OM and nutrients crucial for assessing the risks of pollution and for adopting the socially, politically, and scientifically robust strategies for the management of wetlands.

“…The enhancement of boundary habitats and their boundary effects can limit pollen and fruit dispersal, increasing the number of soil plots susceptible to invasive species and enhancing species invasion. Researchers [13] found that urbanization increased the loss of native species and invasion of exotic species in Atlantic white fir Chamaecyparis thyoides wetlands, preventing the development of wetlands. It was also found that sediment accumulation from urban runoff and frequent streambed disturbance limit algal blooms, and that sediment metal accumulation in streambeds has devastating effects on algae [14].…”

Wetland is an integrated ecosystem which includes ecosystems such as hydrology, soil, vegetation, and biological environments. At present, the urbanization rate of China’s national economic development process is rapidly increasing, and by the end of 2021, the urbanization rate of China’s resident population will be 64.72%. This paper analyzes the hydrological effects of urbanization, the impact of water resources, climate change, and biodiversity on wetland ecosystems, and also analyzes the role of wetlands on the ecological environment, especially in terms of ecological and cultural values. The economic and social benefits of the whole society are also analyzed. The ecological and social benefits of urban wetlands have made their conservation and sustainable development increasingly important worldwide. Based on the current situation of China’s urban wetland protection and restoration, we put forward countermeasures and suggestions for China’s urban wetland protection. This is conducive to promoting the sustainable development of the urban wetland ecosystem, promoting the operation of the market, realizing the optimal allocation of ecological resources, improving the benefits of ecological environmental protection, and promoting the coordinated development of the ecological environment. This paper provides a reference for the better development of wetland conservation under urbanization development conditions.

“…The pollution of aquatic ecosystems has been an international concern in developing countries for decades given its alarming proportions over the past half century [1][2][3]. In the majority of the developing countries, more than 90% of wastewater is discharged directly into nature without treatment according to the United Nations Environment Program (UNEP) report for the year 2006.…”

The present study aimed to assess the physico-chemical quality of wastewater(s) in order to better control the flow of various pollutants generated by the industries from the industrial zone of Cotonou. Water samples were collected in triplicate in each collector and analyzed for their nutrient and metal content (Cu2+, Fe2+, Cd2+, Al3+ and Pb2+) and chemical oxygen demand (COD) and a five-day biochemical oxygen demand (BOD5) were carried out by spectrophotometry. The results revealed highly mineralized waters, indicated by average pH (6.97± 0.34), dissolved oxygen (5.16 ± 0.29 mg/L), electrical conductivity (2280.58 ± 263.97 µS/cm) and total dissolved solids (1076.04 ± 51.01 mg/L). The values of COD (482.05± 1.18 mg/L) and BOD5 (291.67 ±2.19 mg/L) were very high, exceeding the standard for industrial wastewater discharge in Benin respectively by 5 and 11 which is indicative of the presence of very poor biodegradable materials coming essentially from industrial discharge in the study area. The concentration of Cd2+, Pb2+ and nutrient salts indicative of eutrophication were relatively low in the collectors. However, the concentration of Al3+ (2.65±0.03 mg/L) and Cu2+ (10.20 ± 0.14 mg/L) were very high with the later cation being four times higher than the wastewater standard in Benin (2.5 mg/L) for the most heavily loaded collectors. In conclusion, the results of this study provide useful insights for implementation of purification system and efficient management of wastewater from industries.
