Mangroves are a diverse group of trees, shrubs, palms, and ferns growing in the marine intertidal zone or estuarine margins zone where they formed transitional environmental links between inland terrestrial landscape and nearshore marine environment. It plays the role of a dynamic habitation between land and sea (Buffer coastal ecosystem). In my study area, Namkhana block in W.B. (near about world biggest Mangrove environment Sundarban), here I saw that Mangrove is morely degraded due to this area’s people's livelihood. So, I write a paper and find out what is the relation of this area’s Mangrove environment and people's livelihood. Mainly, focused temporally changing the land cover situation of the Namkhana block area’s Mangrove and how the rural livelihood was affected this area’s mangrove? and finally include conservation policy also. Because It feels that, ‘A sea coast without a Mangrove, it looks like a tree without any root!’
