Empowering Women in Reef-Dependent Communities through Seaweed Culture in the Bar Reef Seascape of Sri Lanka

Within the Bar Reef Seascape, many lagoon- and reef-dependent households rely heavily on small-scale fishing and seasonal offshore work. However, declining fish catches, income instability during monsoon seasons, and limited alternative livelihood options have intensified pressure on nearshore ecosystems, including coral reef–associated resources. Addressing these socio-economic and ecological challenges requires solutions that strengthen community resilience while reducing extraction from fragile reef systems.

This initiative introduces seaweed farming as a coral-positive livelihood strategy, with a strong focus on empowering women in reef-dependent households. By providing a predictable, short production cycle and steady income stream, seaweed culture helps reduce economic dependence on reef fishing, thereby lowering pressure on coral reef resources and fostering stronger local support for reef conservation and sustainable management.

The project assessed the technical and social feasibility of seaweed farming in the seascape and connected interested women-led community groups with a private-sector off-taker. Through project-supported de-risking measures, this established seaweed market player was encouraged to expand operations into the Bar Reef Seascape, ensuring that new producers were linked to reliable markets and creating a pathway for scaling up the initiative.

Production focused on Kappaphycus alvarezii, a fast-growing red seaweed widely used in global carrageenan markets and already central to Sri Lanka’s emerging seaweed industry. The species is well suited to lagoon environments due to its rapid vegetative growth, reaching harvestable biomass within approximately 45–50 days under favorable conditions without requiring hatchery inputs. Its proven demand, short cultivation cycle, and low-input production model make it a practical entry point for community-based seaweed enterprises.

By combining women’s economic empowerment, private-sector partnerships, and environmentally sustainable production, this initiative demonstrates how seaweed farming can serve as a scalable, market-connected livelihood alternative that contributes to both household resilience and coral reef conservation in the Bar Reef Seascape.
