The Dying Wetlands of Delhi: An Overview on the Threats and Conservation Strategies of Wetlands
India is endowed with an area of 4.3% of its total geographical area as wetlands, out of which Delhi share accounts for only 0.02% (2771 sq. km). Though wetlands comprise of only 4% of the total earth’s surface, these are the most productive ecosystems and provide a wide range of ecological services like recharging of groundwater, food, raw materials, habitat for wildlife, recreational values, etc. But these fragile ecosystems are under tremendous stress due to different anthropogenic activities like developmental activities, unplanned urbanization, pollution and growth of population, particularly in metropolitan cities like Delhi. As a consequence, there have been a decline in the hydrological, economic and ecological functions provided by the wetlands. This paper concentrates on the important wetlands of Delhi and gives an account on its importance and the continuous threats they are exposed to. It also discusses the management and restoration techniques that can be deployed to retrieve these dying entities.
