Regional Programme of Action on Land-Based Activities Affecting Coastal and Marine Areas in the East Asian Seas – RCU Technical Reports Series No. 5

This report presents a regional assessment of land-based activities affecting coastal and marine environments in the East Asian Seas and outlines a programme of action to address pollution sources and environmental degradation. It reviews the context of increasing coastal pollution associated with urban development, agriculture, industry, and inadequate wastewater management across participating countries in the region. The document compiles national information on pollution sources, environmental impacts, institutional arrangements, legislation, and monitoring systems, including water quality assessment practices. Based on this assessment, it describes strategies and coordinated regional actions aimed at controlling land-based pollution, strengthening monitoring and regulatory frameworks, improving wastewater and waste management, and enhancing cooperation among governments and institutions responsible for marine and coastal environmental protection.
