Regional evidence | Global standards

WIOMSA is a science-policy platform connecting researchers, governments, and practitioners. Access regional status reports, publications, policy briefs, data platforms, and thematic working groups.

Western Indian Ocean Region

From coral reefs and seagrass meadows to offshore seamounts and high seas ecosystems, the WIO is globally significant. These ecosystems sustain livelihoods, protect coastlines, store blue carbon, and support migratory species and ocean connectivity.

Strategic Partnerships

Invest in the Western Indian Ocean

Strategic investment in science-driven conservation, monitoring systems, and workforce development will determine whether the region achieves 30×30 and long-term resilience. Partner with WIOMSA to secure one of the world’s most vital ocean regions.

Our Vision

A prosperous Western Indian Ocean region with healthy rivers, coasts and oceans—supported by science, guided by policy, and sustained through regional cooperation.
