Increasing the contribution of Africa’s fisheries to food security through improved management
Africa is the poorest continent, with the fastest population growth, the most acute food shortages, and overfishing. Meeting rising food demand while preserving sustainable production is challenging. We evaluated the full fishery supply chain over the previous 70 years in search of sustainable growth paths, from fish resource status and fishery production to trade and human consumption. Our data show that Africa had the lowest per capita fish consumption of any continent in 2017, with international imports accounting for 35% of this low fish consumption. Meanwhile, foreign vessels fish legally or illegally in African waters, landing 3.1 million tonnes of fish outside of Africa each year. Current fishing practises have resulted in 40% of fish populations being overexploited, causing a loss of 2 million tonnes of fish production per year. Improved management can reduce non-trade fish outflows from foreign vessels fishing and restore overfished stocks to maximum sustainable levels, increasing Africa's fish consumption by 42% and the commercial value of marine fisheries by 53%. Aside from food supply and economic benefits, there are also various social and environmental benefits including job opportunities, support for local livelihoods, and environmental health. These findings can help inform policy and the development of long-term sustainable solutions to challenges in Africa such as overfishing, low fish consumption, hunger, and poverty.
期刊介绍:
Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches.
Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet.
From this perspective, the journal covers the following areas:
Global food needs: the mismatch between population and the ability to provide adequate nutrition
Global food potential and global food production
Natural constraints to satisfying global food needs:
§ Climate, climate variability, and climate change
§ Desertification and flooding
§ Natural disasters
§ Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production
§ Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production
The sociological contexts of food production, access, quality, and consumption.
Nutrition, food quality and food safety.
Socio-political factors that impinge on the ability to satisfy global food needs:
§ Land, agricultural and food policy
§ International relations and trade
§ Access to food
§ Financial policy
§ Wars and ethnic unrest
Research policies and priorities to ensure food security in its various dimensions.
