In Ogoniland, Rivers State, restoring a mangrove forest is about far more than planting trees. It means repairing damaged wetlands, rebuilding livelihoods tied to fishing and harvesting, and giving communities a stronger role in protecting the ecosystems they depend on.
At the centre of this effort is the Lokiaka Community Development Centre, led by environmentalist Martha Agbani. The initiative has brought women and girls into mangrove nursery cultivation and restoration, demonstrating how community-led environmental action can connect ecological recovery with skills development and income generation.

Lokiaka reports that between 2.6 million and three million mangrove seedlings have been planted since 2016, covering approximately 190 hectares. The project has also trained hundreds of Indigenous women and girls in nursery cultivation and biodiversity management. While the figures are project-reported rather than independently audited, they show the scale locally driven restoration can achieve when communities become active participants rather than passive beneficiaries.
The Niger Delta contains Africa’s largest mangrove forest and one of the world’s most significant mangrove ecosystems. Yet decades of oil pollution have severely damaged parts of Ogoniland. The United Nations Environment Programme’s landmark 2011 assessment found that contamination from more than five decades of oil operations had penetrated further and deeper than previously understood. In some areas, mangroves were left severely degraded, with roots coated in oil. UNEP estimated that comprehensive restoration could take 25 to 30 years and recommended an initial US$1 billion environmental restoration fund.
The scale and duration of that challenge have made community participation increasingly important.
Lokiaka, founded by Agbani in 2003 and involved in mangrove restoration since 2016, trains local women to establish nurseries, raise seedlings and participate in restoration activities. The approach recognises that people living closest to damaged wetlands possess valuable knowledge of local conditions and have a direct stake in seeing restoration succeed.
There has also been a learning curve. Early planting efforts placed seedlings too close together, resulting in overcrowded canopies. The project subsequently adopted more consistent spacing practices. Such adjustments highlight an important lesson for restoration programmes: planting numbers alone cannot measure ecological success. Survival, growth, biodiversity recovery and long-term maintenance are equally important.
The restoration effort is also creating economic opportunities. Local nurseries produce mangrove seedlings that can reportedly sell for between ₦500 and ₦1,000 each, providing income for women involved in raising them. Some Ogoni women have also been engaged by the Hydrocarbon Pollution Remediation Project (HYPREP) to share their technical knowledge and participate in mangrove planting under government-led rehabilitation efforts.
This creates a potential pathway for community expertise to move from small-scale initiatives into larger restoration programmes.
Mangroves also matter because of their ability to store carbon. Research from the Niger Delta has found substantial carbon stocks within mangrove ecosystems, much of it held below ground in soils and sediments. This gives restoration a wider significance as countries and communities explore the potential of blue carbon — the carbon stored in coastal and marine ecosystems.
But carbon opportunities must be approached carefully. Credible blue-carbon projects require evidence that restored trees survive, ecosystems remain protected, and local communities are not displaced or excluded from the benefits. A large planting figure does not automatically translate into an equivalent climate benefit.
Restoration is further complicated by invasive species such as nipa palm, which can spread through disturbed wetlands and compete with native vegetation. Clearing invasive growth before planting native mangroves requires labour, technical knowledge and careful environmental management.
Government intervention remains essential. HYPREP was established to implement UNEP’s recommendations, but the pace and effectiveness of remediation have continued to attract criticism from stakeholders. Community restoration therefore cannot substitute for addressing the pollution that caused the ecological damage in the first place.
The experience in Ogoniland points to a broader lesson for Africa. Environmental restoration works best when communities are treated as partners with knowledge, skills and economic interests, while governments provide the regulation, financing, technical standards and long-term oversight required for restoration to endure.
For the Niger Delta, the opportunity extends beyond replacing lost trees. Healthy mangroves can support fisheries, protect wetlands, strengthen local livelihoods and store significant amounts of carbon. But achieving those benefits requires sustained restoration, pollution prevention, independent monitoring and protection of community interests.
The real measure of success will not be the number of seedlings planted. It will be whether those seedlings survive, whether damaged ecosystems begin functioning again, and whether the communities that depend on them can build more secure livelihoods in the process.
