Thailand Seaweed Market Trends:

Strengthening Resilience and Sustainability in Seaweed Cultivation

Thailand is gaining renewed attention in regional seaweed farming through a new international collaboration aimed at boosting biosecurity and minimizing disease outbreaks. This approach is especially relevant as climate variability puts added pressure on aquatic crops. The project focuses on making cultivation more resilient and sustainable by working directly with Thai academic and development partners. Local livelihoods and marine ecosystems stand to benefit from this effort, which is positioned to bring new research, monitoring, and disease management strategies into the field. Backed by a UK research body and regional institutions, the initiative brings new energy to a sector with economic potential, especially for coastal communities that rely on seaweed farming as a primary or supplemental income. These factors are intensifying the Thailand seaweed market growth. For example, in April 2025, the Natural History Museum launched GLOBALSEAWEED-Protect, a UKRI-funded project to strengthen Southeast Asia’s seaweed sector. With Thailand as a key regional player, the initiative aims to boost biosecurity, combat crop disease, and improve climate resilience. The three-year effort would support local livelihoods and biodiversity, working with institutions across the region, including Kasetsart University and Yunus Thailand.

Empowering Coastal Women through Sustainable Caulerpa Farming

In southern Thailand, Caulerpa farming is creating new income opportunities for women in low-income coastal communities. A grassroots project in Satun Province is equipping participants with farming kits and hands-on training to grow this high-demand seaweed sustainably. The approach isn’t just about farming, it’s helping women increase their earnings and self-reliance. Interest is growing, with plans underway to involve more communities and introduce processed seaweed products. This signals a practical move toward fairer and more eco-conscious aquaculture, where small producers and coastal households play a central role. As the model scales, it’s shaping a more inclusive direction for Thailand’s seaweed cultivation, where economic empowerment and environmental care go hand in hand. For instance, in January 2025, Yunus Thailand launched a Seaweed Social Business project in Satun Province to empower low-income women through sustainable Caulerpa seaweed farming. The initiative provides training and farming kits, helping participants boost income and confidence. With growing interest, the project plans to expand by developing value-added products and engaging more communities. It marks a shift in Thailand’s seaweed sector toward inclusive, environmentally friendly practices that support local livelihoods and coastal sustainability.
