When Energy Projects Sit on Ecological Fault Lines
The Senegal–Mauritania gas coast is one of them.
Along the Atlantic coast shared by Senegal and Mauritania lies one of West Africa’s most ecologically dense stretches of shoreline. It is not dramatic in the way rainforests are, or visually obvious like coral reefs in shallow waters. Its importance is quieter and easier to overlook.
Each year, millions of migratory waterbirds use this coast as a refuge on their journey between Africa and the Arctic. The region’s wetlands, mudflats, and shallow marine ecosystems are part of a long-distance system that operates on seasonal rhythms, not political boundaries.
This is also where BP plans to extract and liquefy offshore fossil gas.
That overlap is not incidental. It is structural.
What sits in the impact zone
On the Mauritanian side, Banc d’Arguin National Park supports more than 250 bird species and is one of the most important migratory bird habitats on the planet. On the Senegalese side, the Marine Protected Area near Saint-Louis is home to dolphins and whales that rely on relatively undisturbed waters.
Just 15 kilometres from the planned LNG terminal lies Langue de Barbarie National Park, a critical nesting site for sea turtles. Around 35 kilometres away, Djoudj National Bird Sanctuary hosts over 1.5 million birds and is recognised as a UNESCO World Heritage site.
These are not marginal landscapes. They are functioning ecological systems whose value lies in continuity - uninterrupted migration routes, stable breeding grounds, and intact food chains.
The risk that rarely makes headlines
Beyond visible wildlife impacts, there is another layer that receives even less attention: the cold-water coral systems offshore.
The Senegal–Mauritania basin hosts what is considered the world’s largest cold-water coral reef. This ecosystem took over 200,000 years to form. It also stores significant amounts of carbon in its structure and surrounding sediments.
Industrial offshore activity - drilling, seabed disturbance, increased shipping, thermal and chemical discharge - carries risks that are poorly reversible at these timescales. Damage here is not a matter of restoration projects or compensatory offsets. It is effectively permanent.
“If not BP, then someone else”
One argument often raised in defence of such projects is inevitability. Even if BP were to step away, the governments involved remain committed to developing offshore gas. Another company would likely step in.
That argument matters, but not in the way it is usually presented.
If development is treated as inevitable, then the quality of environmental governance becomes even more important, not less. Weak assessments, narrow impact boundaries, or rushed approvals lock in damage across decades. Strong assessments, precautionary planning, and enforceable safeguards at least create the possibility of harm reduction.
What should come before extraction?
Before any operations begin, a rigorous, independent environmental risk assessment is not a procedural box to tick. It is the only point at which trade-offs can still be meaningfully examined.
This means:
assessing cumulative impacts, not just project-by-project effects
treating migratory routes and offshore ecosystems as connected systems
acknowledging uncertainty where data is limited, rather than smoothing it away
Technology can reduce some risks. Strategic planning can mitigate others. But neither works without a clear recognition of what is at stake.
Energy transitions are not only about what we build. They are also about where we choose to build and what we are willing to risk in the process.
