Sustain Value led on the sustainable financing component of an assessment to help establish the foundations for a sustainable blue economy in the South West Indian Ocean. Our role was to evaluate the current financing landscape and mechanisms, and identify key barriers, gaps and opportunities, with a view to recommending how to unlock financing for a sustainable blue economy. The study covered Kenya, Madagascar, Mozambique, South Africa and Tanzania, and involved a detailed literature review and interviews with regional experts. The assignment included investigating associated institutional and policy foundations. The study was led by Resolve through a Resolve-Sustain Value consortium involving several leading regional experts within the team.
