Changwon Declaration Toward an Ocean-based Blue Economy : Moving Ahead with the Sustainable Development Strategy for the Seas of East Asia

September connected regional decisions with local action—from a new declaration in Busan to community-led work across the region.

In Busan, the 2026 PNLG General Assembly adopted the Busan Declaration on Promoting Local Coastal Resilience and Sustainable Blue Economy and welcomed Atauro Island, Timor-Leste, as the Network’s newest member. Meanwhile, PEMSEA Founder Dr. Chua Tia-Eng returned to the PEMSEA Resource Facility for a discussion with colleagues on  PEMSEA’s history, lessons, and continuing role in advancing sustainable coastal and ocean governance.

PEMSEA project updates include the GEF/UNDP/ASEAN IRBM Project advanced planning for food and biodegradable waste management in the Pasac-Guagua Watershed, while the PRICELESS Project brought stakeholders together in Regions 3 and 4A to tackle challenges and priorities for the Philippine Rise.

In the Philippines and Timor-Leste, MEP partners under the MOF/PEMSEA Marine Plastics ODA Project mobilized communities, schools, government agencies and civil society organizations for International Coastal Cleanup activities, turning awareness of marine plastic pollution into action on the ground.

The Fourth Regional Steering Committee (RSC) Meeting of the GEF/UNDP/ASEAN Project on Reducing Pollution and Preserving Environmental Flows in the East Asian Seas through the Implementation of Integrated River Basin Management (IRBM) in ASEAN countries was held on 08 July 2026 in Vientiane, Lao PDR, in conjunction with the 26th Meeting of the ASEAN Working Group on Water Resources Management (AWGWRM). Co-chaired by Mr. Oudomsack Philavong, AWGWRM Chairperson, and Mr. Gerd Trogemann of UNDP Bangkok Regional Hub, the meeting brought together 55 participants from ASEAN Member States (AMS), the ASEAN Secretariat, UNDP, PEMSEA Resource Facility (PRF), and the East Asian Seas Executive
Committee, both in-person and online.

The Meeting reviewed implementation progress of the six participating ASEAN Member States and the regional component, including key achievements, lessons learned, implementation challenges, co-financing delivery, and planned next steps. The RSC also reviewed progress in implementing the approved Mid-Term Review (MTR) Management Response, the preparation of the 2026 Project Implementation Report (PIR), the planned activities for the third and fourth quarters of 2026, and the proposed 2027 Annual Work Plan and Budget, including the proposed no-cost extension of the Project.

The 18th East Asian Seas (EAS) Partnership Council (PC) Meeting was held on July 22-23, 2026 at Aloft Novena Singapore, 16 Ah Hood Rd in Singapore.

Onsite participants of the meeting included the EAS PC Chair and Co-Chair; the Technical Session Chair and Co-Chair; the Intergovernmental Session Chair and Co-Chair; the Executive Director of the PEMSEA Resource Facility (PRF); Country Partners (CPs) from Cambodia, China, Indonesia, Japan, Lao PDR, Philippines, Republic of Korea (RoKorea), Singapore, Timor-Leste, and Viet Nam; Non-Country Partners (NCPs) from the ASEAN Center for Biodiversity (ACB), Korea Institute for Ocean Science and Technology (KIOST), Korea Maritime Institute (KMI), Korea Marine Environment Management Corporation (KOEM), National Marine Hazard Mitigation Service (NMHMS), Ocean Policy Research Institute – Sasakawa Peace Foundation (OPRI-SPF), Oil Spill Response Limited (OSRL), and the PEMSEA Network of Local Governments (PNLG). Observers include the Coordinating Body on the Seas of East Asia (COBSEA) and the PEMSEA Network of Learning Centers (PNLC). The meeting also welcomed its first-ever youth delegate, Dr. Kenny Pang of the Singapore Institute of Technology.

In the Philippines, multi-sectoral stakeholders in Bicol and Cagayan Valley provided inputs for the local implementation of the PRICELESS Project and the management of the Philippine Rise Marine Resource Reserve (PRMRR). At the 4th ASEAN Blue Economy Forum, PEMSEA called for concrete investments to address the triple planetary crisis while protecting marine biodiversity and coastal livelihoods.

In Busan, the upcoming 2026 PNLG–PNLC Joint Learning Forum Technical Session will examine nature-based, network-driven pathways for local blue economies, including approaches to coastal resilience and sustainable economic opportunities from marine and coastal ecosystems.

Meanwhile, the GEF/UNDP/ASEAN IRBM Project brought together representatives from six ASEAN Member States for a regional workshop on environmental monitoring and reporting in support of IRBM program development and implementation. Participants also visited sites in the Ciliwung River Basin to examine practical applications of environmental monitoring, including industrial wastewater treatment and the Online Realtime Waste Water Quality Monitoring System (SPARING).

Across the region, PEMSEA partners came together to reflect on progress, strengthen partnerships, and chart the path forward for a resilient East Asian Seas region. At the center of these conversations was the 18th East Asian Seas Partnership Council Meeting in Singapore, where PEMSEA Country and Non-Country Partners reviewed key achievements, agreed on strategic priorities, and reaffirmed a shared vision for healthy coasts, resilient communities, and sustainable blue economies. The field visit to Singapore’s Sungei Buloh Wetland Reserve offered participants an opportunity to see firsthand how conservation efforts and nature-based solutions contribute to resilient coastal ecosystems.

Collaboration extended well beyond the EAS Partnership Council Meeting. This month saw the approval of revised pilot projects in three Philippine sites and continued preparations for implementation in Timor-Leste under the MOF/PEMSEA Marine Plastics ODA Project, bringing local governments one step closer to turning plans into action. The GEF/UNDP/ASEAN Integrated River Basin Management (IRBM) Project also marked several milestones, convening regional dialogues on  river basin governance, holding its 4th Regional Steering Committee Meeting, and advancing pilot project development through field missions and local engagement.

Taken together, these stories reflect a busy July and show how regional cooperation is translated into practical solutions—through partnerships, informed decision-making, and sustained action on the ground.
