The embankment behind Sabita Mondal’s house broke twice in three years. Each time, salt water ruined her family’s fields and pond. This time, the village did not wait for a new concrete wall.

Over two years, families have planted roughly 2 lakh mangrove saplings along the most exposed stretches. Women run the nurseries; fishermen plant at low tide.

Mangrove roots trap silt and soften waves. Older plantations nearby have already shown how much damage they can absorb, and the community hopes its young forest will do the same within a few years.
