Over 70% of the planet's surface is cover with water, yet when it comes to protecting and restoring oceans health, finance is sorely missing. Indeed, only 0.01% of all climate finance is invested into marine and coastal nature based solutions. In this fourth episode of the Financing Nature COP27 Special Series with UNEP, Karen Sack, executive director at the Ocean Risk and Resilience Action Alliance, and Yabanex Batista, Deputy Head of the UN's Global Team for the Global Coral Reef Fund, discuss the role of coastal communities and our seas in climate mitigation and adaptation, and what we need to see to mobilise greater investment.
