Seaweed farming has become a key component of Zanzibar's economy, driven by increasing demand from the food, pharmaceutical, and cosmetics industries. The natural thickening and stabilizing properties of seaweed are utilized in various products, including toothpaste and face creams.
An estimated 25,000 individuals, predominantly women, are employed in seaweed farming across Zanzibar, making it the third-largest export sector following tourism and spices. The industry provides economic opportunities in a context where formal employment for women is limited.
Environmental and Operational Challenges
Rising water temperatures due to climate change are affecting traditional shallow-water farms, necessitating a shift to deeper waters. This change requires seaweed farmers to adapt, including acquiring swimming skills to access new farming areas safely.

Innovation and Sustainability Initiatives
Efforts are underway to enhance the safety and profitability of seaweed farming. Mwani Zanzibar, a local company, is training women to process seaweed into value-added products such as soaps and lotions. This approach aims to increase local profits and reduce the physical demands on farmers.
Global companies and organizations are investing in the sector to improve yields and promote sustainable practices. For instance, Cargill has partnered with The Nature Conservancy to support the industry, while the Global Seaweed Coalition focuses on sustainability and fair labor standards.
Seaweed farming is central to Zanzibar's "blue economy" strategy, which seeks to enhance economic growth through the sustainable use of marine resources. For the women involved, this industry represents not only a means of livelihood but also a pathway to economic empowerment and community resilience.
