Since 2022, Planète Urgence, Orange and Cameroonian communities have restored 100+ hectares of Wouri-estuary mangrove near Douala — including a 3-ha Bojongo pilot at ~70% sapling survival — against a 30-year, 1,000-ha target, as national mangrove loss continues near 3,000 ha/yr.

Context

Since November 2022, Planète Urgence has partnered with Orange, Sia Partners and Cameroonian authorities on CAMERR, targeting 1,000 hectares of mangrove restoration in the Wouri and Ntèm estuaries over a 30-year horizon to 2052.

Activities

A closely monitored 3-hectare pilot at Bojongo in Douala shows planted saplings at a roughly 70% survival rate, with a nursery holding over 7,000 seedlings and 12 local residents employed in restoration work.

Results

As of late 2025, the programme had restored more than 100 hectares nationally.

Conclusions

Cameroon loses an estimated 3,000 hectares of mangrove per year, so restoration is still running far behind loss.

Implementation
Indicative cost
Medium (€50k–€500k) — Partnership funded by Orange (telecom operator) and Sia Partners (consultancy) alongside Planète Urgence and Cameroonian authorities; per-hectare cost not published.
Time to results
Long (> 3 years) — Programme running since November 2022 toward a 30-year target (to 2052).
Staffing & skills
Planète Urgence field teams, 12 local residents employed in restoration work, Orange and Sia Partners programme partners

Conditions for success

  • nursery-based sapling production (7,000+ seedlings)
  • local employment component

Common failure modes

  • Cameroon loses ~3,000 ha of mangrove per year, so restoration still runs far behind national loss
