The document aims to establish a foundational perspective on regional marine ecosystem health and contamination trends to assist national and international decision-makers in formulating management strategies. Relying on scientific literature, reports, and monitoring data, the assessment characterizes the region’s geography, oceanography, and significant human pressures, including waste disposal, coastal development, and marine transport. Key findings indicate that while some localized improvements have occurred through environmental regulations, mounting population pressures and industrial activities continue to affect marine water quality and habitats. The report underscores the necessity for sustained regional cooperation and environmental management. DS UN Environment Document Repository RD Sep 17, 2026
