Mangroves are among the most carbon-dense ecosystems on Earth — sequestering up to five times more carbon per hectare than tropical rainforests and locking it in deep, waterlogged soils for centuries. This project, led by a coastal community that depends on the mangrove belt for fisheries and shoreline protection, actively replants and restores a degraded stretch of coastline. Community members serve as trained mangrove guardians, monitoring seedling survival and protecting the restoration zone. Beyond carbon sequestration, the project delivers rebuilt fish nursery habitat, reduced coastal erosion, and improved resilience to storm surges.
