Biodiversity

The CMPA of Bamboung is part of a marine and coastal eco system that stretches from Senegal to Mauritania in the north, to the islands of Cape Verde up to Guinea including the archipelago of Bijagos in the south west. This large eco system is characterized by the presence of the upwelling phenomenon along the coastline of deep ocean waters, which is rich in mineral and organic nutrients. Besides these upwellings, the ecological variety in this sector materialises in cross-border migration of fish, water birds, marine mammals and reptiles.

Bamboung, a great diversity of habitats

In the Saloum Delta, the bolong (inlet) of Bamboung consists of a wide variety of habitats (sandy areas, gravel, mangroves, salt flats, sea grass beds, small inlets, pits and shoals). In the water of the bolong, a certain level of salinity, caused by the sea, is always present, but varies seasonally. This diversity of habitats and the seasonal variability of their physical and chemical characteristics and microclimates, favour the presence of a wide variety of wildlife species (birds, reptiles, mammals), especially fish and flora.

Overfishing. The major cause for the degradation of this eco system

In recent decades, the negative effects of coastal fishing have been multiplied by the development of motorised fishing. The changing dynamics of fishing has decreased the number of employed people in the sector as well as the density of the fish population. Areas with plenty of fish became fragmented and disconnected from each other, and older and large sized groups of fish have nearly been wiped out. Consequently, some fish populations are at risk of extinction.

The paletuvier mangrove is also threatened. It mainly degrades due to excessive salinity caused by a lack of seasonal rainfall and by men’s logging activities.

The ecological impact of the CMPA is scientifically recognised

Scientific studies conducted by the Institute of Research for Development (IRD Marseille) have shown that the CMPA in Bamboung has rapidly delivered positive changes since its inception. After three years, the return of 23 species had been identified, including the return of large predators such as dolphins, captains and barracudas.

The return of marine resources to the CMPA enriches peripheral fishing areas, and allows fishermen to increase their catches and hence their incomes.
