Book excerpt: The marine areas beyond national jurisdiction (ABNJ) comprises 40 percent of the earth’s surface, it covers 64 percent of the surface of the ocean and 95 percent of its volume. The Common Oceans ABNJ Program (2014-2019) was implemented by FAO as a concerted effort to bring various stakeholders to work together to manage and conserve the world’s common oceans. The project “Strengthening global capacity to effectively manage ABNJ”, one component of the Common Oceans ABNJ Program, addressed cross-sectoral coordination and dialogue among the separate ongoing processes - a key gap that limited effective ecosystem-based management of ABNJ. The project supported participation and knowledge sharing amongst decision makers in cross-sectoral governance of ABNJ. Limitations to the project design, budget and accountability should be addressed to foster corrective action for phase two of the ABNJ Program.
