Seaweed farming provides cash income for many women of local communities in Zanzibar. Seaweed farmers, 80% of whom are women, face several environmental, social and economic challenges. These include climate change, weak representation of women producers, difficulties in accessing international markets and insufficient protection of coastal ecosystems. Seaweed farming activities are usually small-scale and carried out in the intertidal zones largely in marine conservation areas, near mangroves and coral reefs. In response, an integrated coastal management approach and blue economy strategy were applied in Zanzibar.
