About this book

Environmental threats to Anasagar wetland include pollution, eutrophication, encroachment,siltation, weed infestation, unplanned, aquaculture practices etc. These are causing serious problems for the area and are proving detrimental to the growth of the system: it is noted that, while dissolved oxygen content was low, the conductivity values indicating presence of pollutants was found to be high. Both the parameters are unsafe for aquatic life. Pollution is being caused from garbage, waste, sewage, detergents, fertilizers etc. from run off processes. This nutrient rich water 175 result in explosive growth of Azolla, Hydrilla, Potamogetion, Vallisneria, etc. Ceratophyllium is a well-adapted macrophyte to water rich in inorganic Nitrogen. Trapa is cultivated as a source of food. Pesticides have broadly contaminated natural water resources, which gain entry into the biota of the area where it is represented in a toxic form. With the occurrence of a total dry phase during summer in Anasagar, truckloads of basin area soil are being taken out after digging the bed. This results in the loss of rich storage of nutrients from the bottom habitat.
