State of the Northwest African marine fisheries resources Press briefing to accompany the International Symposium on Marine fisheries, ecosystems and societies in West Africa: half a century of change held in Dakar, Senegal, June 24-28 2002 Prepared by the Sea Around Us Project, University of British Columbia, Vancouver, Canada in collaboration with WWF-International
West Africa has a long tradition of fishing, via both local and distant water fleets … This graph illustrates the reach of Ghanaian fishers during the period up to 1959
The fish wealth of West Africa has also attracted distant water fleets from other continents … Number of ‘country access years’ by area, 1960-1969
Number of ‘country access years’ by area, 1980-1989 … and these have increased tremendously over the years …
… finally reaching the present, staggering levels. Number of ‘country access years’ by area, 1990-1999
What is the impact of all this fishing on the resource base? We show this impact for the countries of the Northwest African sub-region using a methodology previously applied to the North Atlantic and which is documented at www.fisheries.ubc.ca; www.fisheries.ubc.ca This methodology is based on maps of catch data and twenty ecosystem models, as presented at the Dakar Symposium by Villy Christensen, Reg Watson, and other members of the Sea Around Us Project.
Thus, we have found for West Africa, similar trends as for the North Atlantic … 1900 1999 Biomass Fishing intensity
Conclusions The fish resources and ecosystems of Northwest Africa are as depleted as those of the North Atlantic and the fisheries are not sustainable; Surplus fishing vessels shifted from the ‘North’ to the ‘South’ will not increase catches; Rather, they will continue to undermine the development and food security of the West African countries.
Colleagues in West Africa, notably the members of the EU-funded SIAP project (Fisheries Information and Analysis System); The Environmental Program, Pew Charitable Trusts; The Sea Around Us Project Team at the Fisheries Centre, UBC, Vancouver, notably Villy Christensen (biomass maps), Reg Watson (catch maps) and Jackie Alder (country/fishing access maps).
