    Wet land depletion - Serious natural calamity

    Have anyone heard about wet land depletion. Wet lands are areas of land in which the soil is saturated with water seasonally or permanently. Such lands may also be covered with shallow pools of water. Wet lands may also include marshes, swamps, bogs, rice paddies etc. The water in the wet land can be fresh water, saline water, or brackish water. A wet land can be distinguished from other water bodies based on the water level and the nature of plants living in them. Wet land is a transition from a dry land into a water body. Urbanization, constructional activities like stadium, airports, flats, agricultural and industrial developments, climatic change, etc.

    Effects

    1) Habitat loss for variety of animals, fishes, birds, and plants.
    2) Increase in flood, soil erosion, etc.
    3) Introduction of pollutant into water bodies.
    4) Reduce the quality and quantity of ground water.
    5) Climatic change and global warming.
    6) Reduces atmospheric ability and loss of biodiversity.

    Major Wet lands are categorized as Ramsar sites. Any human interference in such sites are prohibited by UNEP of United Nations. Here in Kerala the Vembanad Lake and the adjacent wet lands come under this Ramsar group. But what is happening here. How much area has so far been converted into residential plots, how much for resorts/flats/industries/etc. ?

    Among the wetlands in India, the Vembanad-kol wet land ( 1512.5 sq.km)is the largest, followed by Odisha's Chilka lake (1185 sq.km).Both of these come under Ramsar sites. Ramsar sites in India are most threatened. Lots of activities are concentrated on these sites resulting in the reduction and contamination of the sites.

    Vegetation is lost there, water is polluted constructions are taking place there, salinity getting increased which makes the conditions unfit for several species of living organisms. Thus these and other (totally 26 Ramsar sites have been identified in India) sites are slowly losing the ecological properties which are expected from such sites.
