The next INBO World Basin Summit will be held from June 16 to 19, 2026, in Brazil, at the invitation of the Rio de Janeiro State Secretariat for the Environment and Sustainable Development (SEAS).
After Marrakesh and Bordeaux, Rio de Janeiro will host this major international event dedicated to Integrated Water Resources Management (IWRM) at the basin level, formerly known as the INBO World General Assembly.
The aim of this summit is to bring together IWRM stakeholders from around the world to share experiences, tools, and best practices deployed at the basin level.
It brings together 200 to 400 participants, representing national and transboundary basin organizations, national, regional and local administrations, technical institutions, UN agencies and international financial institutions.
The program of the World Basin Summit spans four days.
The first day of the Summit (Tuesday, June 16) will be dedicated to workshops. Topics to be addressed include: basin governance, inter-sectoral coordination, alignment of water resource management policies with coastal and marine management policies (“blue economie”), and the interface between science and water resource management policies.
Five thematic plenary sessions will be held on Wednesday, June 17, and Thursday, June 18:
1. From data to action: modernizing water resources monitoring for resilient basin management
2. City-Basin dialogue for water security: reconciling urban and rural developments
3. Healthy waters, resilient basins: bringing consistency to water and biodiversity policies
4. Climate change adaptation at basin level: controlling floods and droughts
5. Circular water economy for basin resilience: diversifying the ‘water mix’ with non-conventional resources
The Summit will conclude with technical and cultural visits on Friday, June 19.
