Impact of High Seas Closure on Food Security in Low Income Fish Dependent Countries

Area of Science:

• Marine conservation and fisheries management
• Food security and socio-economic impacts
• International resource governance

Background:

• High seas closure is a conservation measure impacting transboundary fish stocks.
• Many low-income countries rely heavily on fish for nutrition and livelihoods.
• Understanding the socio-economic implications of high seas closure is crucial for vulnerable nations.

Purpose of the Study:

• To assess the impact of high seas closure on the availability of consumed fish in 46 vulnerable countries.
• To evaluate how domestic consumption of straddling fish species influences potential benefits.
• To determine the direct and indirect effects of high seas closure on food security.

Main Methods:

• Analysis of fish consumption patterns in 46 fish-reliant and/or low-income countries.
• Modeling projected net catch gains and losses following high seas closure.
• Comparing domestic consumption of straddling species with projected catch changes.

Main Results:

• 54% of assessed countries consume straddling fish species domestically.
• 70% of countries are projected to have net catch gains, but only 37% consume these species domestically.
• 25% of countries face net losses, with less than half domestically consuming straddling species.

Conclusions:

• High seas closure's direct benefit to domestic fish supply in vulnerable countries may be limited.
• Impact on food security varies; indirect economic benefits are possible.
• While potentially improving sustainability, high seas closure requires careful consideration of socio-economic impacts on impoverished nations.
