Seaweed farming presents a sustainable and high-potential avenue for enhancing livelihoods in Tanzania’s coastal communities especially in the mainland (Kilwa, Lindi, Mafia, Mtwara, Bagamoyo, Tanga and Zanzibar.) By introducing and scaling seaweed farming as a primary income source, this initiative will focus on equipping local populations, especially women and youth, with skills in farming, harvesting, and processing seaweed. With low input costs and minimal environmental impact, seaweed farming provides a reliable livelihood option while promoting marine ecosystem health. Training programs will include methods for producing value-added products such as seaweed fertilizers, cosmetics, and food items, thereby increasing income opportunities. The initiative will also foster market linkages, ensuring that communities can sustainably grow and sell their products both locally and internationally. This holistic approach will empower coastal communities, create jobs, and contribute to long-term economic resilience within the blue economy framework.
