President of the International Water
Resources Association (IWRA)

Dear Colleagues,
On behalf of the International Water Resources Association (IWRA), I am delighted to invite you to IWRA’s XIX World Water Congress, taking place in Marrakech, Morocco, December 1-5, 2025.

IWRA is a professional international network of multi-disciplinary and multi-sectorial experts committed to advancing research, building capacity, and promoting science-based policy solutions and practices for the sustainable management of water resources. For over five decades, IWRA has been bridging the gap between science, policy, practice, driving innovation, and shaping water and sustainable development agendas, while advocating for meaningful progress. While IWRA has accomplished remarkable achievements over the past five decades, we acknowledge that considerable work remains to address future water resource challenges. We will continue to build on and expand our activities to adhere to the needs and possibilities of the future, including thematic congresses, master classes, webinars, policy briefs, geographic chapters, and task forces, as well as collaboration with key partners. Most importantly, we will continue to promote the World Water Congress as a key activity.

The World Water Congress, IWRA’s flagship event since 1973, is one of the most prestigious platforms for sharing groundbreaking research, building partnerships, and influencing water governance from local to global scales. In its 19th edition, the Congress will focus on the theme: “Water in a Changing World: Innovation and Adaptation”. This theme reflects the growing need for innovative solutions and adaptive strategies to manage water resources in the face of climate change, environmental degradation, and increasing societal and economic as well as ecological demands. Together with the Moroccan government, we are proud to convene policymakers, researchers, practitioners, the private sector, and industry leaders from around the world. This Congress will provide an opportunity to exchange knowledge, showcase innovations, and co-create actionable solutions for the complex challenges of global water governance, security, and sustainability.

Building on the success of the XVIII World Water Congress in Beijing and aligning with major events like the UN Water Conference and the 10th World Water Forum, the XIX World Water Congress aims to foster collaboration, dialogue, and innovative solutions in addressing todays and tomorrow’s pressing water issues.
As President of IWRA, I extend my heartfelt gratitude for your support and participation. I look forward to welcoming you in Marrakech in 2025 to engage in this crucial conversation and collectively shape the future of water resource management!
