Co-production of resilient green infrastructure in urban river management through community participation and partnerships in Payakumbuh City, Indonesia

River infrastructure is vital in maintaining ecological and social resilience, particularly in urban areas vulnerable to environmental degradation and flooding. This study focuses on the Batang Agam River in Payakumbuh City, analyzing collaborative arrangements among local government, city administration, and communities in river management. A qualitative approach was employed with purposive sampling techniques. Data were collected through observation, documentation review, and in-depth interviews with local government officials, river care communities, and local business actors. Analysis was conducted using the Manual Data Analysis Procedure (MDAP). The findings reveal the critical role of the River Care Community Forum as a mediator, activity facilitator, and supervisor of cleanliness, order, and security across river segments. Government support was evident through participation in cleanup campaigns, facility provision, and program oversight, involving subdistrict offices, the Environmental Agency, and the Civil Service Police Unit. Beyond its ecological function, the river area has become a space for community economic empowerment through small-scale enterprises such as culinary businesses, parking services, and other micro-businesses, all managed environmentally sustainably. Overall, this collaboration revitalized the river ecosystem and contributed to achieving the Sustainable Development Goals, particularly Goal 17 on partnerships, while serving as a model for community participation-based sustainable solutions.
