For healthier and more sustainable diets, look to fisheries and aquaculture

Doubling of global demand for aquatic foods calls for a ‘blue food revolution’ to tackle climate change and malnutrition, new research argues. New landmark assessment finds fish, shellfish and algae offer untapped potential for global development if the right policies and investments are put in place.

An unprecedented review of the aquatic foods sector has uncovered how fisheries and aquaculture can play a greater role in delivering healthy diets and more sustainable, equitable and resilient food systems around the world.

Five peer-reviewed papers highlight the opportunities to leverage the vast diversity of aquatic, or “blue”, foods in the coming decades to address malnutrition, lower the environmental footprint of the food system, and provide livelihoods.

These five papers are the first in a series produced by the Blue Food Assessment (BFA), a group of more than 100 leading researchers led by Stockholm Resilience Centre at Stockholm University, Stanford University, and EAT.

“Blue foods are much more diverse than typically thought, and so too are the many communities of small-scale fishers who are often overlooked despite providing the majority of blue food people eat,” said Professor Beatrice Crona, co-chair of the BFA and Deputy Science Director at the Stockholm Resilience Centre.

The research projects that global demand for blue foods will roughly double by 2050, and will be met primarily through increased aquaculture production rather than by capture fisheries. Investing in innovation and improving fisheries management could increase consumption even more and have profound effects on malnutrition. The research found that blue food systems facing the highest risk from climate change are also typically located in those regions where people rely on them most and where they are least equipped to respond and adapt to climate hazards.
