The Biodiversity Conference has set a goal to place at least 30% of land and marine areas and their species richness under protection by 2030. OECMs are alternative forms of protection that could be crucial to conserve the diversity of the planet’s species in addition to nature reserves. A new study involving the Leibniz Centre for Tropical Marine Research (ZMT) has mapped coastal and marine areas in Indonesia that could be recognized as OECMs. The study will serve as a basis for decision-making by the Indonesian government.
