Recognising the vast potential of its maritime resources, Zanzibar has set a forward-looking goal to transform into a prominent blue economy center by 2050; however, this vision is accompanied by numerous challenges, necessitating a dedicated focus on sustainable resource management and the strengthening of coastal resilience against environmental vulnerabilities

A researcher at the Zanzibar Seaweed Cluster Initiative, Dr Flower Msuya, said seawater temperatures have risen from 31°C to 38°C, causing pest infestations and diseases. Despite the difficulties, Dr Msuya and other experts are exploring Integrated Multi-Trophic Aquaculture (IMTA), which combines seaweed farming with other species such as sea cucumbers. Nevertheless, she pointed out that “access to boats, swimming skills, and land shortages continue to challenge many farmers, especially women.” In Zanzibar, seaweed farming supports over 30,000 people, 80 percent of whom are women. Despite the ongoing challenges, the industry remains a vital source of livelihood for many coastal communities. The Principal Secretary of Zanzibar’s Ministry of Blue Economy and Fisheries, Captain Hamad Bakar Hamad, said there is a need to improve infrastructure and market access as seaweed farming plays a crucial role in Zanzibar’s economy, supporting fisheries and tourism, which sustain two-thirds of the population.
