This analysis was conducted by UN Environment, the International Coral Reef Initiative (ICRI) and UN Environment World Conservation Monitoring Centre, in response to United Nations Environment Assembly (UNEA) Resolution 2/12 on sustainable coral reef management and the ICRI 2016-2018 Action Plan Goal 1.2, which encourages financing for projects and initiatives helping to protect and restore coral reefs, mangroves and seagrasses. The analysis was funded by the Government of France. Trends in international funding for the conservation and sustainable management of coral reefs and associated ecosystems were drawn from a dataset of 314 projects with project initiation dates ranging from 1 January 2010 to 31 December 2016. The dataset was collated and verified between mid-2017 and early 2018 through desk-based online searches, supplemented by direct contact with funders, where possible. Spatial analyses were conducted at national and regional levels. Funding allocations were categorised under eight broad themes focused on the objectives of the funding: conservation and sustainability; marine protected areas management; promoting sustainable living and alternative livelihoods; fisheries management and governance; climate change resilience; communication and awareness; monitoring and research; and policy and legislation. In instances where co-financing information was not provided, the reported financial value was taken to represent the primary funding value.
