More than 40 representatives from seven countries reviewed the national and regional plans for the conservation of marine biodiversity in the Coral Triangle Initiative area, their impact on the Aichi targets and Sustainable Development Goals. During the workshop a marine spatial planning exercise was used to understand the importance of multi-sectoral decision making and to train the participants on how to use biodiversity resources, including OBIS, in the decision making process. All the training materials are available on the OceanTeacher website.
