The Kolkata Municipal Corporation area generates roughly 600 million liters of sewage and wastewater and more than 3500 metric Tons of garbage every day and recycled at designated sites in the East Kolkata Wetlands. The garbages are used in 900 ha for Vegetable farming as fertiliser. The wastewater is used for aquaculture in around 254 fisheries and also for irrigation in vegetable cultivation. It constitutes a unique system of resource recovery, in which nutrients are extracted from the city's waste water through fish farming and agriculture for which East Kolkata Wetlands are designated as Ramsar site. Changes in land use, changes in hydrological regimes, and stakeholder conflicts are rapidly degrading the system. So, Study of Land use change is the foremost requirement for system management.
This paper is aimed to detect the change in Land use of the East Kolkata Wetland Area using temporal data included ALOS AVNIR II data and Study the effect of change in land use in the existing sewage flow system, change in crop status in the sewage fed farms and condition of sewage fed fishery ponds. The study reflects that land use change is taking place which is alarming to the ecosystem. It also found that management failure and urban encroachments are other threats for the sustainability of the system.
