Wetlands are broadly defined as areas where water is the primary factor controlling the environment and the associated plant and animal life. Wetlands today are under extreme pressure of extinction due to anthropogenic reasons. Delhi was once known to have more than thousand wetlands. The most recent inventorization of wetlands, which was carried out as part of the Delhi Climate Action Plan – 2009 to 2012 lists 621 wetlands out of which many are already dry, encroached or no longer exist. This is very concerning since wetlands in Delhi act as buffer against monsoon flooding and also help recharge the now rapidly declining ground water. The project will carry out inventorisation, environmental assessment and sustainability appraisal of wetlands in North Delhi area (as delimited by North and North-west districts) of the NCT of Delhi. The wetlands will be assessed based on pre-determined criteria such as ecological assessment, threat perception and sustainability appraisal. An attempt will be made to make the wetland inventory data public in an interactive manner so as to invite public participation in the project.
