The African continent produces seven million tonnes of marine fish a yr. This seize has elevated lately thanks to improved catches in west Africa and the tip of Somalian piracy within the Indian Ocean.
But the expansion in provide can’t match the rising demand. Africa’s population is predicted to attain 1.7 billion in 2030 and a couple of.5 billion in 2050. Fish consumption is already 7.5kg per capita per yr. It would want to develop to 13 million tonnes of marine fish in 2030 and virtually 19 million tonnes in 2050.
These figures present an thought of the size of the manufacturing hole: about six million tonnes in 2030 and 12 million in 2050. Much change is required to attain such targets.
We did a study evaluating the potential for growth of fisheries and aquaculture within the area to overcome this manufacturing hole and make sure the meals safety and livelihoods of the millions of folks throughout the continent who rely upon fisheries and fishery assets for survival and revenue.
Our major discovering was that regardless of the pressures fisheries face, there may be monumental potential to enhance the productiveness of the fisheries. At the identical time there may be potential to enhance the well being of coastal and marine environments and supply new avenues for job creation.
This evaluation can be used to inform sustainable fisheries growth and governance of sustainable exploitation of fisheries assets. This is especially essential given the rising consideration given to the event of Africa’s “blue economy”.

Threats and alternatives
Climate change and the related alterations in fish distribution patterns pose vital threats to catch potential and to the safety of coastal communities. Reductions in water high quality by way of air pollution, habitat destruction, and unsustainable and harmful fishing practices imperil the power of ecosystems to assist fisheries.
It’s arduous to handle ecosystems successfully when there’s a lack of information.
Fish don’t keep inside nationwide boundaries and this raises advanced points. Jurisdictions overlap and governance of fish assets is poor in any respect ranges. It has tended to deal with quantity of manufacturing. This mixture of points has already precipitated the over-exploitation of all main fish assets.
Despite the threats, there are nonetheless alternatives to safe the longer term of African marine fisheries.
Firstly, the continental fish market is giant, with high demand and increasing purchasing power. Africa is a net importer of fish however has the potential to turn out to be a internet exporting continent.
Secondly, there may be rising consideration and finance being invested within the well being of ecosystems. Efforts are being made to mitigate biodiversity loss and the results of local weather change. Coastal ecosystems have an essential position in carbon sequestration and coastal safety. Restoring them helps shield fishery assets.
Lastly, with the rising significance of creating the blue financial system, fisheries are being built-in right into a a lot wider administration system. They are gaining increasing attention for his or her contributions to blue progress.
Securing the longer term
Making use of these alternatives has the potential to considerably enhance the manufacturing of Africa’s marine fisheries. There are three key areas of intervention:
- restoring ecosystems to well being
- enhancing the sustainability of fisheries operations
- enhancing harvest and post-harvest chains.
According to our evaluation, restoring ecosystems to a wholesome situation may enhance fish manufacturing by 50-60%, including 9-10.5 million tonnes to annual internet provide by 2050. Healthy ecosystems have extra talents to present valuable providers to people, and extra so the fisheries. Healthy ecosystems act as nurseries, feeding grounds, and breeding grounds for varied species essential to the fisheries.
This worth can be exceeded by way of extra correct valuation of ecosystems, rising the position of marine protected areas in fisheries administration, and improved marine spatial planning.
An extra two to three million tonnes of fish internet provide might be delivered by 2050. It can be achieved by enhancing the sustainability of fisheries operations and decreasing the environmental footprint of fleets and processing industries.
Proper transboundary administration ought to deal with resolving international entry agreements, and addressing casual and unlawful fishing.
Operations can do extra to restrict the waste of bycatch and discard.
Improving harvest and post-harvest chains has the potential to ship 1.5-2 million tonnes internet provide by 2030. Scaled-up mariculture (fish farming) can supply two to 4 million tonnes. Adding worth to merchandise – for instance smoking and drying fish – can scale back losses that are actually 35% of harvests.
Finally, Africa can scale back its vulnerability to exterior shocks by boosting intra-regional trade and limiting exports. The dietary wants of African nations ought to come first. Links on the African degree want to be solid and funding channelled into regional collaborative mechanisms for commerce.
For every of these 4 areas of intervention, particular options exist. Most of them have already been applied with success – they only want to be promoted and scaled up.
Within the present continental, regional and nationwide blue financial system schemes, pathways can be found to combine fishing with restoring ecosystems. Together they can present advantages for biodiversity, meals safety, and local weather change mitigation and adaptation.
