The figures come from fieldwork on the Dutch Caribbean island that has not yet been published and which the researchers describe as a first analysis. A Wageningen Marine Research report published last year put average coral cover on Bonaire at under 10% and said algae now dominate the reefs. The reef is central to a climate case Greenpeace Nederland brought against the Dutch state. The Hague district court ruled in January that Dutch climate policy breached the human rights of Bonaire’s residents and treated them unequally with people in the European Netherlands. The organisation Reef Renewal said it has planted 20,000 pieces of new coral around the island, while acknowledging the scale is not enough to solve the problem.
