Addressing Nutrient and Wastewater Pollution in the East Asian Seas

Land-based marine pollution, including nutrient waste, sediments, and wastewater, is one of the most significant threats affecting the East Asian Seas (EAS). Agriculture, aquaculture, domestic and industrial waste contribute to the marine pollution problem in the region. Marine pollution not only alters the integrity of the environment but also has detrimental effects on human health. While all EAS countries implement governing policies to reduce pollution, there remain gaps to effectively address the issue, including monitoring, awareness and capacity, and enforcement. Considering connectivity between the marine environment and shared ecosystems such as transboundary watersheds, marine pollution is also a transboundary challenge requiring a regional management approach. The East Asian Seas Action Plan 1994 recognized the need for a regional action to prevent and manage pollution in the region, which is also highlighted in COBSEA’s strategic directions. 

Objectives:

• Present the updated draft nutrient reduction strategy for the East Asian Seas;
• Explore potential synergies and opportunities in addressing nutrient and wastewater pollution; and
• Guidance from COBSEA participating countries in consolidating nutrient and wasterwater activities in the COBSEA region.
