    Abstract The Great Barrier Reef, a natural wonder, is usually associated with colourful fish and incredible beauty. But beyond its pretty looks, the Great Barrier Reef and coral reefs like it around the world provide essential services to ecosystems and local communities. Between a quarter and a third of all marine species spend a part of their lifecycle in coral reefs. Nearly a billion people depend on corals for their livelihood and food security, for example through related tourism business and fishing. Corals also protect coastlines and those living in close proximity to the coast. Reefs break waves and reduce current velocities and as such greatly contribute to coastal risk reduction. Approximately 200 million people are estimated to depend on coral reefs for protection from storm surges and waves. But currently we are losing our corals at an unprecedented level around the globe. The Great Barrier Reef experienced the most widespread amount of bleaching in 2020; and this for the third time in only five years. This technical background report for the 2020/2021 edition of the Interconnected Disaster Risks report analyses the root causes, drivers, impacts and potential solutions for the Great Barrier Reef bleaching through a forensic analysis of academic literature, media articles and expert interviews.
