Accelerating and upscaling ocean conservation action in the Western Indian Ocean

A high-level meeting of African Ministers and governments convened by H.E. President Azali Assoumani of Comoros adopted the ‘Moroni Declaration‘, underlining a common vision to harnessing the continent’s blue economy.


The Great Blue Wall is a Western Indian Ocean (WIO)-born, African-driven roadmap to achieve a nature-positive world by 2030.

It aims at unlocking unprecedented nature-based recovery efforts through dramatically accelerating and upscaling ocean conservation action while enhancing socio-ecological resilience and the development of a regenerative blue economy. It aspires to achieve this by catalyzing political leadership and financial support.


The Great Blue Wall has three clear objectives or pillars to be achieved by 2030, crafted to respond to the three interconnected crises that comprise biodiversity loss, climate change, and economic decline.
