Analyzing the impact and evolution of ocean & coastal management: 30 years in retrospect

Ocean & Coastal Management (OCMA) has significantly contributed to international ocean and coastal management, policy-making, governance, and other related research fields. This article highlights the contributions OCMA has made in these areas by summarizing the trends in 3782 articles published from 1992 to 2021. Using bibliometric and knowledge graph visualization analyses, this article systematically reviews the historical research contributions in each field and identifies emerging topics in recent years, such as the Blue Economy, shipping, and marine litter. OCMA has made a substantial positive impact on global ocean and coastal management by fostering collaboration among scholars and practitioners, advancing policy and regulatory development, enhancing management practices, increasing public awareness of environmental protection, and promoting sustainable development. In addition to its critical academic role in the field of ocean and coastal management, OCMA has also facilitated advancements in related research and practice (such as coastal erosion, litter, port management), ultimately contributing to the protection of global ocean and coastal ecosystems.
