Oceánium runs the largest mangrove restoration program worldwide, in Senegal, where 45,000 hectares of its mangroves – a quarter of the total surface area – have been lost since the 70s.

Restoring the mangroves in Senegal provides a natural protection against floods, a carbon sink, a natural nursery for many species (some consumed by the local population), and protects agricultural fields further inland by reducing the entry of saline water.
