Wetlands are one of the most productive ecosystems, comparable
to tropical evergreen forests in the biosphere and play a
significant role in the ecological sustainability of a region.
They are an essential part of human civilisation meeting many
crucial needs for life on earth such as drinking water, protein
production, water purification, energy, fodder, biodiversity,
flood storage, transport, recreation, research-education, sinks
and climate stabilizers. The values of wetlands though
overlapping, like the cultural, economic and ecological factors,
are inseparable. The geomorphological, climatic, hydrological
and biotic diversity across continents has contributed to
wetland diversity. Across the globe, they are getting extinct
