Climate and Ocean Adaptation and Sustainable Transition (COAST) programme The Climate and Ocean Adaptation and Sustainable Transition (COAST) programme aims to improve vulnerable coastal communities' resilience to climate change and prosperity from a more sustainable use of their marine environment. COAST will achieve this through a multi-component approach focused on: i) protecting and restoring coastal habitats providing nature based solutions (e.g. mangroves, seagrass, coral reefs), ii) improving small scale fisheries management, governance, sustainability and productivity, iii) scaling more sustainable, climate resilient, low carbon aquaculture production by coastal communities and the private sector, and iv) strengthening coastal planning and governance. COAST will focus in up to six priority countries, first building evidence around themes ii) and iii) and supporting science based blue carbon policies, followed by regulatory strengthening and grants for local level projects. COAST is part of the UK's £500m Blue Planet Fund portfolio.
