Macroalgae Farming Boosts Sustainable Growth in Latin America

International experts explained that macroalgae cultivation represents a key driver of sustainable development for marine-coastal communities and blue economies across Latin America. The findings align with FAO’s new guidelines for sustainable aquaculture.

During a regional workshop, specialists highlighted the nutritional value of seaweed, particularly its high iodine content and other essential micronutrients. They also emphasized the urgent need to establish clearer, more efficient, and coordinated regulatory frameworks to enable the sector’s orderly growth throughout the region.

"Risks and threats related to biosecurity, climate change impacts, and pollution were also discussed. Addressing these challenges will require monitoring systems, ongoing research, and adaptive management plans tailored to the specific characteristics of each region and ecosystem." said Alessandro Lovatelli, FAO Aquaculture Officer. 

Despite successful experiences in Brazil, Chile, and Venezuela, most macroalgae farming initiatives in Latin America remain small-scale or at early development stages. According to FAO data, macroalgae production in Latin America and the Caribbean grew 66% between 2013 and 2023, reaching 22,125t in 2023. Brazil, Chile, and Venezuela dominate regional production, accounting for more than 90% of output. 

Most countries in the region still have untapped or underdeveloped potential for macroalgae cultivation. Experts noted that species diversification and support for emerging producers could bring significant economic and environmental benefits. Achieving this requires strategic investment and stronger regional collaboration to improve sector resilience, broaden market access, and unlock the full potential of macroalgae farming in Latin America and the Caribbean.

Workshop participants agreed on the need to enhance research and technological development along the entire value chain, from species selection to post-harvest processing. "This includes the use of artificial intelligence and biotechnology to optimize efficiency, improve traceability, and strengthen the sustainability of crops," said José Aguilar-Manjarrez, Aquaculture Officer, FAO Latin America and the Caribbean.

The group also recommended promoting integrated multitrophic aquaculture and restorative aquaculture models that boost profitability while delivering environmental benefits. Community-based approaches were identified as essential for ensuring the sector’s social sustainability.

Experts called on FAO to support the creation of an international seaweed platform, provide specialized technical assistance, facilitate experience exchange among countries, and develop practical information tailored to producers’ needs. Moreover, governments were urged to strengthen regulatory frameworks, increase investment in research and innovation, and implement comprehensive training programs for aquaculturists.

The private sector, both artisanal and commercial, was encouraged to incorporate local knowledge, diversify product offerings, and actively promote equity and inclusion at all stages of sector development.

The regional workshop on macroalgae cultivation gathered 27 experts from Argentina, Brazil, Chile, Ecuador, Mexico, Peru, and Venezuela. It was organized by the FAO Fisheries and Aquaculture Division and the FAO Regional Office for Latin America and the Caribbean, in collaboration with the Institute of Aquaculture and Environment at Universidad Austral de Chile.
