RT null T1 COBSEA collaborative action framework on nutrients management A1 United Nations Environment Programme, A1 Coordinating Body on the Seas of East Asia, K1 nutrient management K1 marine ecosystem K1 coastal ecosystem YR 2024 FD 2024-01 LK https://wedocs.unep.org/handle/20.500.11822/47736 UL https://wedocs.unep.org/handle/20.500.11822/47736 NO This document presents a regionally coordinated strategy adopted by the Coordinating Body on the Seas of East Asia to address nutrient pollution affecting marine and coastal ecosystems. It outlines a collaborative framework focused on reducing the impacts of excessive nutrient emissions—particularly from agriculture, untreated sewage, aquaculture, and groundwater discharge—using a science-based, source-to-sea approach. The framework supports COBSEA member states in strengthening national strategies, policies, and pilot initiatives that reduce eutrophication, hypoxia, and nutrient runoff. Emphasizing watershed-scale planning and cross-sectoral cooperation, the document promotes integration of local knowledge, stakeholder engagement, and alignment with global goals such as the SDGs, UNEA resolutions, and the Kunming-Montreal Global Biodiversity Framework. Key principles include balancing ecological, social, and economic considerations and tailoring solutions to national contexts.
