Indonesia's plan to ban seaweed exports, aimed at encouraging domestic processing, could negatively impact the country's largest marine aquacultural activity, affecting around 62,000 farmers. The ban could lower commodity prices, reduce national production, and may not aid domestic processors in competing with large foreign companies. Instead, the government could stimulate the seaweed industry by aiding farmers in becoming more productive and sustainable, supporting domestic processors in upgrading to efficient technologies, investing in research and development, and implementing a national system for satellite monitoring of marine aquaculture.
