The Coral Research & Development Accelerator Platform – CORDAP – was launched in 2020 by the G20 to fast-track research and development solutions to save the world’s corals. Current coral restoration is among the most expensive restoration, is dominated by short-term projects, suitable only for small-scale intervention, and has the lowest success rate. CORDAP will bring together the best minds worldwide, in a transdisciplinary approach, to accelerate and scale up the development of new technologies that support international coral conservation efforts needed to secure a future for tropical coral reefs and deep-water corals. Unique in its time-sensitive mission, G20 CORDAP will support, complement, and scale up existing and new initiatives working on coral conservation, resilience, adaptation, and restoration.
