WETLANDS

Wetlands are transitional areas between terrestrial and aquatic zones, where the water table is near the land surface and the land is covered by shallow water.The Ramsar Convention, 1971 was held to protect the wetlands of international importance and ensure the sustainable use of such wetlands.The science dealing with wetlands is called paludology.
  Such wetlands are the life support systems for the people living in the zones, winter resort for the migratory birds and they work as bulwark againsta encroachment by the sea, buffer against storms and hurricanes and provide habitat to various flora and fauna in the region.Moreover they are important as tourist places,scientific and educational interests, and they provide ample vegetables for the people and green fodder for the livestock.Moreover, they provide habitat to mangroves and play very important role in maintaining biodiversity of the world.
