The traditional fishing heritage of the Imraguen people in Mauritania is facing severe threats from climate change and overfishing [1].
This decline endangers more than just a local economy. The Imraguen represent a centuries-old method of sustainable harvesting that relies on ancestral knowledge and wind-powered vessels to maintain the ecological balance of the Banc d’Arguin [1], [3].
Located in the Banc d’Arguin region, the Imraguen have long utilized specialized boats to navigate the coastal waters [1], [2]. However, these practices are now being undermined by a combination of environmental shifts and industrial pressures [1]. The gradual loss of ancestral knowledge among younger generations further complicates the survival of these traditional techniques [1], [3].
Overfishing has depleted the stocks that the Imraguen rely upon for their livelihoods [1], [2]. As industrial fleets increase their presence in the region, the small-scale, traditional wind-powered boats struggle to compete or find sufficient yields to sustain their communities [1].
Climate change has introduced further instability to the region [1]. Shifts in ocean temperatures and weather patterns affect the migration and availability of fish, making the traditional lunar and seasonal calendars used by the Imraguen less reliable [1], [3].
Efforts to preserve this cultural legacy face an uphill battle as the environment changes. The intersection of ecological collapse and the erosion of cultural memory threatens to erase one of the most distinct maritime identities in West Africa [1], [3].
“The Imraguen fishing heritage and livelihoods are being threatened.”
The crisis facing the Imraguen highlights a broader global trend where indigenous ecological knowledge is being lost simultaneously with the ecosystems it manages. Because the Imraguen use low-impact, wind-powered technology, their disappearance may signal a shift toward more aggressive, industrial fishing methods in the Banc d’Arguin, potentially accelerating the biological degradation of the region.
