Mangroves, a predominant coastal habitat in the tropics, are constantly threatened by various anthropogenic pressures deteriorating them to a great extent. Global emissions of green house gases (GHGs) are likely to raise the world temperature and the sea level at the rate of 0.3 ºC and 6 mm 10 Yr-1 by the year 2100. Mangrove habitats would be more vulnerable to climatic changes and resultant sea level rise (SLR) because of their unique location at the interface of the sea, by altering eco-biological processes. It may extend the intertidal and supra tidal zones further inland resulting changes in existing ecological set up. The limitation of the landward margin would cause vertical rise resulting in water logging ultimately killing mangroves and dependent biota. The present document describes mangrove habitats and related issues from the Indian subcontinent in the context of climate variations and SLR, and recommends integrated long term monitoring.
