The report, Red List of Mangrove Ecosystems, is the first global mangrove assessment for the International Union for Conservation of Nature (IUCN).
It warns that half of the world’s mangrove ecosystems run the risk of collapse.
The report shows that 50% of the mangrove ecosystems assessed are at risk of collapse.
Under business as usual, 25% of the global mangrove area is predicted to be submerged in the next 50 Years.
By 2050 about ~7,065 km2 (-5%) more mangroves will be lost and ~23,672 km2 (-16%) will be submerged.
Indian mangrove ecosystems have been bunched into three parts.
The ecosystems in the Bay of Bengal region shared by India and Bangladesh and those in the west shared by India and Pakistan are in the least concerned category.
However, the mangrove ecosystem in the south, which India shares with Sri Lanka and Maldives, is categorised as critically endangered.
