Zanzibar is strategically positioning itself to capitalize on a projected $11.8 billion global blue economy market by 2030, shifting from traditional small-scale fishing and seaweed harvesting to attracting private investment in modern fisheries infrastructure, aquaculture, and marine exports. The Tanzanian government is actively seeking private sector participation through various investment models, including public-private partnerships and joint ventures, to unlock the value of underutilized marine resources. Efforts are underway to move beyond feasibility studies and address investor concerns regarding environmental, social, and climate-related risks, with the UNDP providing $500,000 in technical assistance grants to enhance project attractiveness. The seaweed sector, Zanzibar's second-largest export supporting approximately 15,000 households, is being transformed from a subsistence activity into a more structured, commercially viable industry with improved processing, quality standards, and market access, while financial institutions like CRDB Bank are providing significant financing to local fisher groups.
