2019 was a year of remarkable progress and impact for WIOMSA. The 2019 Annual report captures how WIOMSA has worked mindfully and effectively to take advantage of the opportunities presented to work at the intersection of science, management, policy and society in the coastal and marine environment of the Western Indian Ocean region. The various sections of the report give a comprehensive update on our developments, priorities, targets, and achievements in 2019. Find out how we have built the Association, the key figures for the year, the substantive work of our programs and activities, our partners, our members, our gatherings and our finances. The highlight of the report is the reflection on the 11th WIOMSA Scientific Symposium; one of the most successful conventions since the first symposium was held in 1997.
