This report analyzes the potential and challenges of seaweed farming in Chile, within the broader context of the national aquaculture sector's transition toward more sustainable and regenerative models. While Chile remains a global leader in aquaculture production, the industry faces environmental and economic challenges due to its dependence on intensively exploited species such as salmon. In this context, the report focuses on seaweed farming as a regenerative alternative, with the potential to diversify production and strengthen coastal economies.
Although seaweed farming currently accounts for only 3% of national production, seaweed has enormous development potential and is a key alternative for developing restorative aquaculture models. Current production is largely based on an extractive model that limits added value and generates strong pressure on natural meadows, especially in regions where artisanal extraction is still dominant. Expanding seaweed cultivation represents a strategic opportunity for building a more sustainable and balanced industry that could capture carbon, mitigate environmental impacts on aquatic ecosystems, and enable the production of seaweed for diverse uses. In addition, this transition could reduce pressure on natural habitats while creating new opportunities for coastal communities, including women and indigenous peoples, who have historically played an important role in the use of seaweed.
The report proposes a sectoral roadmap andaction plan for a sustainable seaweed farming industry in Chile. The aim is to establish a triple impact model (economic, social and environmental), promoting seaweed farming in a sustainable and collaborative manner, and fostering valueadded products. The roadmap and action plan integrate international recommendations, such as the adoption of regenerative technologies, the importance of support and investment in R&D&I, circular economy approaches, equitable access to resources, investment and the strengthening of local capacities. These are organized into four strategic pillars and 20 key actions to be implemented over a five-year period.
