The wetland ecosystems are one of the most essential ecosystems of the world which aids in water cycle replenishing on the globe (CBD, 2015; RCW, 2018). It is the largest carbon stores of the world and has the most extensive net primary productivity (Cronk and Fennessy, 2001; Joosten et al., 2016). Due to its enormous beneficial services like providing food, fuel, fiber, freshwater, sewage management, pollution control, erosion protection, nutrient recycle and enriching biodiversity its referred to as ‘Kidneys of the Earth’ (Russi et al.,2013; Costanza et al.,2014; NIE, 2015; RCW, 2018). According to the RCW, 2018 the total wetland cover area of the globe is 12.1 million square kilometers of which 31.8% is in Asia. In India out of the total recorded 2, 01,503 major wetlands (SAC, 2011) spread in 0.15 million square kilometers, there are total 77 Ramsar wetland sites spread across 1.9 million Ha.
