Analysis of the global marine biodiversity security assessment

Purpose The study aims to assess marine biodiversity security, which is closely linked to a healthy planet and societal well-being. It defines marine biodiversity security, identifies threats such as climate change, marine debris and invasive species and explores mechanisms impacting this security to aid in achieving Aichi Targets and enhancing ecological sustainability. Design/methodology/approach Using spatial statistical methods, the research analyzes the temporal and spatial distribution of marine biodiversity. It provides a comprehensive multi-layered perspective on the current state of global marine biodiversity, facilitating the identification of threats and the understanding of their mechanisms. Findings The findings indicate significant threats to marine biodiversity, with an emphasis on climate change, marine debris and invasive species. The report reveals the spatial distribution of endangered species and underscores the need for urgent actions to address these threats and improve marine biodiversity security globally. Originality/value This report serves as a critical reference for promoting healthy, productive marine biodiversity that supports societal welfare. It underscores the importance of establishing a protective framework for marine biodiversity, contributing to the realization of the United Nations Sustainable Development Goals, particularly SDG 14.
