The great blue wall is a Western Indian Ocean (WIO)-led, African-driven roadmap to achieve a nature-positive world by 2030.

It aims at unlocking unprecedented nature-based recovery efforts through the establishment of a transformational movement. its goal is to dramatically accelerate and upscale ocean conservation actions while enhancing socioecological resilience and the development of a regenerative blue economy by catalyzing political leadership and financial support.

This will be achieved by spearheading the establishment of a first-of-its-kind connected network of nature-people positive seascapes. This network of seascapes will be connected by a living blue wall that will act as a regional ecological corridor formed by conserved and restored critical blue ecosystems such as mangroves, seagrass and corals. While the Great Blue Wall will act as a wall against climate change impacts and biodiversity loss, it will also shelter coastal communities and create the enabling conditions and necessary mechanisms to accelerate the development of regenerative ocean ventures. The Great Blue Wall is an action focused and action-driven regional response to three interconnected crises, i.e. Biodiversity-Climate-Economy with three clear objectives to be achieved by 2030.
