The Ocean Country Partnership Programme (OCPP) supports countries to manage the marine environment more sustainably, including by strengthening marine science expertise, developing science-based policy and management tools and creating educational resources for coastal communities. The programme is funded through official development assistance (ODA) as part of the UK’s £500 million Blue Planet Fund. Through the OCPP, the UK government partners with ODA-eligible countries to deliver positive impacts for coastal communities that depend on healthy marine ecosystems. Bilateral partnerships under the OCPP are primarily delivered by the Centre for Environment, Fisheries and Aquaculture Science (Cefas), the Joint Nature Conservation Committee (JNCC) and the Marine Management Organisation (MMO), agencies of the UK government that possess unique expertise in marine science and management. The OCPP also funds two international initiatives that align with its aims and help to develop global public goods, the Global Ocean Accounts Partnership (GOAP) and the Friends of Ocean Action (FOA). GOAP is a global, multi-stakeholder partnership established to enable countries and other stakeholders to effectively measure and manage progress towards sustainable ocean development. FOA is a platform hosted by the World Economic Forum in collaboration with the World Resources Institute, which brings together ocean leaders from a wide range of sectors to encourage action and investment into sustainable ocean projects.
