Connecting the Corridor: OIA 2023 as the Catalyst for a Nature-Positive Africa
Region: Western Indian Ocean (WIO)
Target Year: 2030
Ocean Impact Area: Large-scale marine conservation and regenerative blue economies
Most people hear “Western Indian Ocean” and think of a horizon. For 70 million people living along this coastline, it is something far more intimate: a supermarket, an employer, and a heritage that shapes identity. But right now, that lifeline is exposed. With only 8% of these waters currently protected, communities are facing climate shocks, collapsing biodiversity, and economic instability simultaneously.
The scale of the threat calls for more than isolated “spots on a map.” It requires a connected, living corridor—a Wall of Resilience that strengthens nature and livelihoods together. The Great Blue Wall is designed to deliver precisely that.
2030 Vision and Targets
- Biodiversity: Effectively and equitably conserve at least 30% of the Western Indian Ocean (2 million km²).
- Climate: Sequester 100M+ tons of CO2 through the restoration of 2 million hectares of critical blue ecosystems.
- Economy: Benefit 70 million people by creating 2 million blue jobs and unlocking regenerative livelihoods.
Every movement needs a turning point. For the Great Blue Wall, that moment was Ocean Innovation Africa (OIA) 2023, where high-level policy ambition met the African entrepreneurs and community leaders with the grit to build what the moment demands. OceanHub Africa’s role is to ensure these Blue Guardians—the fishers, women-led cooperatives, and youth—are the architects of this future, not just observers.
Through OHA’s Connect vertical, we bridge the “death valley” between proof and scale, aligning grassroots innovators with the capital and institutions that can carry solutions across borders.
Turning Resilience into Reality
- Coalition Built: Mobilized 20+ civil society organizations into a unified front for ocean health.
- Reach Delivered: Through the ReSea project, reduced physical and economic vulnerability for 350,000 women, men, and youth across Kenya, Tanzania, Mozambique, and Madagascar.
- Innovation Supported: Utilized targeted incubation and acceleration to move entrepreneurs toward viable market pathways.
- Grassroots Governance: Integrated community-led governance models to ensure protection strengthens local livelihoods rather than just statistics.
People are rising faster than sea levels. The Great Blue Wall is not only a barrier against disaster; it is a bridge to a prosperous, nature-positive Africa, built with the people who live closest to the ocean and designed to last.
