- Seaweed production globally has grown rapidly in recent decades.
- Most growth was in Asia, but there have been production increases in Africa and Latin America.
- There is growing attention to the potential for seaweed to provide non-terrestrial nutrients without the need for land, freshwater, or chemicals.
- This paper explores opportunities and challenges relating to the farming and commercialization of seaweed in low- and middle-income countries (LMICs).
- Data gaps and coverage impede a full understanding of trends and patterns in what is produced or consumed .
- There appears to be potential for seaweed-related activities to grow in many coastal LMICs.
- That said, such activities would contribute more to food security through income effects than as inputs to diets
- Seaweed can be a high-value export crop contributing to LMIC food security by increasing export potential and household purchasing power.
