SAO PAULO: Chinese architect Kongjian Yu, known for his so-called nature-mimicking “sponge cities,” has died in a small plane crash in Brazil with two filmmakers documenting his work, police said Wednesday. The 62-year-old was considered a leading figure in sustainable urban planning; his “sponge cities” replacing concrete surfaces with natural features that better absorb water in flood situations.
