Kongjian Yu, the pioneering Chinese landscape architect and urban planner credited with coining the "sponge city" concept, has passed away at 62. According to Reuters, he was killed in a plane crash on Tuesday in the wetlands of Mato Grosso do Sul state, in Brazil, while reportedly filming a documentary about his work, after being featured in the opening program of the São Paulo International Architecture Biennale last week.
A globally-recognized advocate for ecological urbanism, Yu gained international relevance after his "sponge city" philosophy was adopted as a national policy in China in 2013. The approach prioritizes nature-based solutions, such as wetlands, parks, and permeable pavements, to absorb and retain water. This novel method stood in stark contrast to traditional concrete infrastructure, offering cities a way to combat urban flooding and accelerate climate change by working with nature rather than against it. His ideas have since been implemented in hundreds of cities worldwide.
