This report presents findings from a national review of incentive-based approaches to support coastal stewardship in Tanzania. Sustain East Africa (SEA) conducted the study, in collaboration with the International Institute for Environment and Development (IIED), as part of Asia–Africa BlueTech Superhighway (AABS). AABS is led by WorldFish and funded by the UK’s Blue Planet Fund, promoting South–South collaboration to strengthen aquatic food systems in ways that benefit nature, people and the climate.
