🌿 Tribute to Professor Kongjian Yu 🌿

The IUCN NbS Management Hub deeply mourns the passing of Professor Kongjian Yu, a true global champion for Nature-based Solutions.

Professor Yu’s visionary leadership has transformed the science and practice of architecture, demonstrating how cities and landscapes can thrive when built in harmony with nature. Through his pioneering concepts—such as the Sponge City approach—he showed the world how NbS can address today’s most pressing challenges: water security, climate resilience, food systems, and poverty alleviation.

His dedication and influence extended far beyond academia, inspiring governments, practitioners, and communities worldwide to reimagine development pathways rooted in ecological wisdom.

At IUCN, we will continue to honor his voice and legacy by scaling Nature-based Solutions globally—ensuring that his life’s work continues to guide our collective journey towards a sustainable future for people and nature.

Our heartfelt condolences go to his family, colleagues, and all who had the privilege to work with him. His leadership will remain a beacon for generations to come.
