Integrated River Basin Management Project

The first quarter of 2026 marked a period of strengthened coordination and forward planning for the GEF/UNDP/ASEAN Integrated River Basin Management (IRBM) Project, as participating ASEAN Member States and partners continued to build on institutional arrangements at national level and advance pilot interventions at basin level. These shared efforts were shaped by closer inter-agency collaboration, alignment of strategies, and a growing emphasis on translating plans into practical, site-based solutions.

In the Philippines, a key activity was the convening of the Organizational Meeting of the Project Steering Committee (PSC) in January, bringing together representatives from national government agencies
to guide project implementation. The meeting clarified the governance structures, including the roles of the PSC, Inter-agency Technical Working Group, and Project Management Unit, while also reviewing and approving the 2026 workplan and budget. Discussions underscored the importance of harmonizing existing plans and programs across agencies to support integrated river basin and water resources management, particularly in the Project’s sites in Cavite and Pampanga.

At the basin level, coordination was further strengthened through a February meeting in Pampanga with the local government and the Department of Environment and Natural Resources for project implementation in Pasac–Guagua Watershed. The discussions provided updates on project implementation, revisited institutional arrangements, and identified priority directions for pilot project development. A notable shift emerged in the exploration of solutions, with stakeholders considering strategies to address solid waste—particularly food waste management—based on data showing that biodegradable waste comprises a significant share of total waste generated in the province. This reflects a more integrated and context-specific approach to address river basin challenges.

In March, the Project continued to support technical discussions on solid waste management through its participation in consultations in Da Nang, Viet Nam, where national and international partners examined priority concerns such as waste segregation, recycling systems, and the environmental impacts of landfill operations. Site visits further informed the identification of technical assistance needs and highlighted opportunities for innovation, including digital monitoring systems and alternative waste treatment solutions, where the Project could contribute.

In Cavite, Philippines, the Project participated in the review and updating of the 10-year Action Plan for the Imus-Ylang Ylang-Rio Grande Rivers (IYRR) Water Quality Management Area (WQMA), which brought together stakeholders to assess progress, identify gaps, and update strategies for improved river basin management. In support to the IYRR Action Plan and as part of pilot project development, the Project conducted the review of two feasibility studies commissioned by the DENR Environmental Management Bureau Region IV-A for the proposed wastewater and/or sewerage/septage treatment system in three river basins in Cavite Province and the Local Water Utilities Administration for the identification of concept designs for sanitation projects in the Municipality of Amadeo. The results were presented to the 1st Quarter 2026 Governing Board meeting of the IYRR WQMA. The IYYR WQMA Governing Board agreed to issue a resolution on the proposed establishment of septage treatment plant (STP) in the Municipality of Amadeo marking a key step toward advancing pilot project implementation under the IRBM Project.

Collectively, the activities of the quarter reflect how these shared currents are beginning to take shape—grounded in strengthened partnerships and a clearer focus on practical solutions. This edition also features a profile story from Kedah River Basin in Malaysia, highlighting the experiences of women and communities whose livelihoods are closely tied to the river. Their stories underscore the vital role of women in sustaining water resources and shaping more inclusive and resilient approaches to river basin management.
 

In Kedah, Malaysia, fishing guides, rice farmers, women food entrepreneurs, river associations, and government partners are working together to sustain Sungai Kedah — the Kedah River — from its forested headwaters in Ulu Muda to the rice plains below. Along its course, communities depend on regulated flows for paddy cultivation, inland fisheries, river-based enterprise, and food traditions that have long shaped Kedah’s identity as the nation’s rice bowl.

Monsoon floods, sedimentation, and pollution place increasing pressure on the basin. Along the river, local groups practice catch-and-release fishing, organize clean-ups, and build enterprises rooted in its waters. At the same time, coordination among state and national agencies — through a Source-to-Sea approach that advances integrated river basin management and governance — is deepening shared responsibility across the basin.

The final quarter of 2025 marked a period of steady progress for the GEF/UNDP/ASEAN Integrated River Basin Management (IRBM) Project, as participating countries continued moving from planning toward implementation. Across the region, this transition was shaped by strengthened governance arrangements, deeper stakeholder engagement, and sustained awareness-raising efforts that anchored the Project more firmly at national and local levels. 

A key milestone in November was the official launch of the IRBM Project in Indonesia, alongside the signing of a Memorandum of Agreement between the PEMSEA Resource Facility and the Ministry of Environment. This agreement formalized the implementing arrangements and collaboration for project implementation in the Ciliwung River Basin in Indonesia.

Earlier in October, a series of consultations in Indonesia, Viet Nam, and Malaysia brought together representatives from national, state-level, and local government agencies to identify and confirm priority issues and pilot solutions for the Ciliwung, Vu Gia–Thu Bon, and Kedah river basins. While each basin reflected its own social and ecological context, the discussions revealed shared challenges—wastewater and solid waste management, flooding, sedimentation, competing water uses, and saltwater intrusion. These common concerns underscored the growing urgency of integrated governance and management approaches in the face of accelerating development and climate pressures.

In December, the Project extended its outreach in the Philippines through participation in the Cavite Coastal Summit and the Cavite Sustainable Development Strategy Workshop. These events provided opportunities to raise awareness on Integrated River Basin Management, share updates on Project implementation in Cavite Province, and introduce the Source-to-Sea approach to local government officials, academe, and stakeholders engaged in environmental planning and management.

During the same month, the Project also convened an online inception meeting to initiate the development of the IRBM Training Manual and Training-of-Trainers (ToT) Program. Representatives from the six participating ASEAN Member States discussed the approach, methodology, and timeline for developing the training manual and ToT program, which will incorporate global practices while being grounded in regional and local contexts and practical application.

Taken together, the activities of the past quarter reflect a year of converging efforts and collective momentum. This journey is captured in the 2025 photo gallery featured in this edition, offering a visual walkthrough of the engagements, partnerships, and milestones that have marked the Project’s steady progression throughout the year. 
 

The GEF/UNDP/ASEAN Integrated River Basin Management (IRBM) Project continued to gain progress in the third quarter of 2025 with strengthened partnerships, wider knowledge sharing, and more active participation in amplifying best practices and local stories across the ASEAN region.

In the Philippines, national implementation advanced with the signing of a Memorandum of Agreement (MOA) between the Department of Environment and Natural Resources (DENR) and PEMSEA Resource Facility sustaining collaboration for project implementation in the Pasac–Guagua Watershed and Imus–Ylang Ylang–Rio Grande Rivers. Additionally, consultations in these two river basins helped identify priority issues for pilot project development and implementation, focusing on addressing water scarcity, improving wastewater management, and promoting nature-based solutions.

In Malaysia, coordination with government counterparts was carried out in preparation for the official launch and full-scale implementation of the Project along the Kedah River Basin. For each participating ASEAN Member State, multistakeholder workshops on Water-Energy-Food-Ecosystem (WEFE) Nexus were held to gather local perspectives and anecdotal information on changes and trends, including gender responsive approaches, relating to water, energy, food, ecosystem, and disaster risk reduction, and potential synergies and trade-offs across these sectors.

At the regional level, the Project expanded its knowledge and capacity building network through initiation of the establishment of IRBM Learning Centers for the Project and linked to the PEMSEA Network of Learning Centers (PNLC). The Project also participated in key international and regional platforms—from Korea’s 20th anniversary celebration of Total Pollutant Loading Management to the GEF Project Oversight Training in the East Asian Seas Region held in the Philippines —sharing lessons learned and best practices on project oversight and implementation.

The Project also highlighted the importance of visual storytelling through local narratives that can drive understanding and action during the GEF IW:LEARN webinar. The Project was also able to profile the Imus-Ylang Ylang-Rio Grande Rivers in the Philippines highlighting community realities and the steps the government has initiated in conserving this river basin.

These collective efforts reflect a shared commitment to integrated and inclusive river basin management - one that bridges science, governance, and community voices to build a more resilient and sustainable future for ASEAN’s river basins and watersheds and associated coastal and marine areas.
 

In Cavite, Philippines, river rangers, mangrove stewards, fishers, artists, and local government partners are working together to restore the Imus–Ylang Ylang–Rio Grande Rivers and their nearby waterways—removing debris, caring for mangroves, and promoting cleaner, more sustainable livelihoods. With continued partnerships, coordinated planning, and stronger local and national governance, these rivers can once again support farms, fisheries, and local livelihoods. As the province of Cavite continues to grow, the restoration efforts demonstrate how progress and conservation can advance together, helping keep these waterways vital for communities.
