Field Spotlight

Limbe & Douala's Coast Under Threat

📰 Source:Cameroon News Agency

📰 Source:DataCameroon

Limbe's iconic Down Beach and the Wouri estuary's mangrove system are under simultaneous assault — from SONARA's petroleum operations in the South West and accelerating urban deforestation around Douala. Together, these twin crises represent one of the most urgent environmental emergencies in Cameroon today.

"I have lived here for over 25 years, but never experienced this type of polluted environment before." — Ngeme John, Batoke fisherman, Limbe

SONARA invested FCFA 620 billion in 2014, scaling refining capacity from 2,100,000 to 3,500,000 tons per year. The consequence has been devastating for coastal communities: Mile Six Beach's iconic black volcanic sand has been decolourised to brown by petroleum spills, and fishermen like Ngeme John are now forced to travel 30km offshore to find viable catches. Bio-resource Centre CEO Augustine Njamnshi warns that in the worst-flooded areas, "only the tops of houses and trees are seen emerging from the water" — a direct result of mangrove forest clearance along the shores.

In Douala, the crisis is equally severe. According to the Cameroon Mangroves Atlas, the Wouri estuary lost 14.3% of its mangrove cover between 2000 and 2015 — from 106,325 ha to 99,730 ha — with the Douala-Bonabéri area recording a catastrophic 6.2% annual destruction rate. By 2015, 14,730 ha of mangrove land had been converted to housing, while 10,703 ha were severely damaged. Edouard Yagouda, Regional Delegate of Environment for the Littoral, has warned starkly: "Douala will one day find itself in water, because the natural barrier that protects it from flooding will have disappeared."

🔬 The Terraqyn Response

The twin environmental crises along Cameroon's Littoral and South West coastlines — SONARA petroleum contamination in Limbe and accelerating mangrove deforestation in the Wouri estuary — represent exactly the kind of complex, multi-factor emergency that demands rigorous scientific analysis. Terraqyn applies systematic soil and water sampling, GIS-based spatial contamination mapping, and ecological risk assessment using validated pollution indices to quantify the extent and severity of coastal and estuarine degradation. Our work directly informs restoration strategies, mangrove replanting programmes, and the regulatory submissions needed to hold industrial and urban actors accountable. The black volcanic sand of Limbe — and the rich biodiversity of the Wouri estuary — deserve to be protected and restored.

January 2026 · Terraqyn Research Notes

Heavy Metal Risks in Volcanic Soils of the Cameroon Volcanic Line

The Cameroon Volcanic Line stretches from Mount Cameroon to Lake Chad — and its volcanic parent material naturally concentrates metals like Cr and Ni. But traffic emissions, pesticide runoff and industrial activity are adding anthropogenic metals on top. We explain how to distinguish natural from human-made contamination using Enrichment Factor analysis.

Mangrove Loss in the Wouri Estuary: Data, Drivers and What Must Change

Between 2000 and 2015 the Wouri estuary lost 14.3% of its mangrove cover — and the rate in Douala-Bonabéri is still accelerating. Using Landsat and Sentinel-2 imagery, Terraqyn mapped the spatial pattern of loss and identified the three primary drivers: urbanisation pressure, timber extraction, and agro-industrial encroachment.

This study assessed the contamination levels and ecological risk of heavy metals (Cd, Pb, Zn, Cu, Ni, Cr) in soils along the Lala-Manjo Highway in Cameroon's Littoral Region. Using systematic sampling protocols, GIS-based spatial distribution analysis, and established pollution indices, the research identified contamination hotspots and evaluated ecotoxicological risk to soil health and food safety — contributing to the scientific understanding of soil contamination dynamics in African volcanic regions.
