PANAMA CITY, January 7, 2026 — A new study reveals that sustainably managing coral reefs could boost global seafood supplies enough to feed an additional 1.4 million people annually, offering a vital pathway to address growing food insecurity.
Reef Revival: A Potential Solution to Global Hunger
Scientists say restoring coral reefs could increase sustainable fishing yields by 50 percent.
- In 2023, 349 million people in 79 countries faced acute food insecurity, a number worsened by conflict and climate change.
- Recovering fish populations on coral reefs could provide up to 162 million additional sustainable servings of reef fish per year to individual jurisdictions.
- A complete fishing ban could allow reefs to recover in under seven years, though alternative livelihoods for fishers would need to be established.
- Healthy coral reefs not only provide food but also income and livelihoods for coastal communities.
The world is grappling with a worsening food crisis. The World Bank has acknowledged figures from the World Food Programme indicating that 349 million people across 79 countries were acutely food insecure in 2023. Since then, the situation has deteriorated, fueled by disruptions to supply chains, the escalating impacts of climate change, global financial instability, and ongoing conflicts in regions like Ukraine and Gaza. Food inflation remains stubbornly high, with “dozens of countries experiencing double-digit inflation,” according to the World Bank.
But there’s a glimmer of hope beneath the waves. Researchers at the Smithsonian Tropical Research Institute (STRI) in Panama, along with colleagues from around the globe, have found that well-managed coral reefs hold the key to significantly increasing sustainable fishing yields. The study, published in a recent paper, estimates that restoring reefs could increase global yields by 50 percent, enough to meet the 226-gram-per-week seafood intake recommendations for an extra 1.4 million people each year.
A: Yes. This research demonstrates that recovering fish stocks on coral reefs can substantially increase the number of sustainable fish servings available, particularly in areas where malnutrition is prevalent. It’s a natural resource with the potential to provide a significant boost to global food security.
The research team analyzed 1,211 individual reef sites across 23 jurisdictions currently operating below maximum sustainable production levels. Their findings revealed that reefs could potentially supply individual areas with between 20,000 and 162 million additional sustainable servings of reef fish annually. The study emphasizes that locations with the greatest potential for increased yields often coincide with those experiencing the most severe food and micronutrient deficiencies, highlighting both the challenges and opportunities at hand.
Many coral reefs are currently depleted, with fish stocks falling below levels that allow for maximum sustainable production. To reverse this trend, the study indicates that fish biomass—the total mass of living organisms in a given area—needs to double. A complete and strictly enforced fishing ban could facilitate recovery in less than seven years. However, the researchers acknowledge the need to find alternative income sources for those who depend on coral reef fisheries for their livelihoods. Sustainable coral reef tourism is one potential avenue, with the Hawaii Institute of Marine Biology (HIMB) finding that limiting visitor numbers can protect coral ecosystems without negatively impacting tourism revenue—and may even benefit the industry in the long run.
Alternatively, if fishing continues at current levels while allowing fish populations to recover, it could take as long as 50 years to achieve the anticipated increase in food supply. The choice, it seems, is between short-term economic considerations and long-term food security.
