Le Sponge Cities, o città spugna, sono un nuovo modello di pianificazione urbana che si propone di rendere le città più resilienti agli eventi climatici estremi, come le inondazioni e la siccità.

Kongjian Yu, a Beijing-based landscape architect, author, and academic famed for pioneering a particularly porous approach to urban design that employs large-scale green infrastructure with recreational elements to mitigate flooding accelerated by climate change, is the winner of the second Cornelia Hahn Oberlander International Landscape Architecture Prize.

Modern challenges such as floods, rising global temperatures and water shortages can be mitigated with a holistic but revolutionary approach – turning the planet into a sponge, a strategy that is already being deployed in more than 250 cities.

October 17, 2023 (Washington, D.C.) – The Cultural Landscape Foundation (“TCLF”) today announced that Beijing-based landscape architect Kongjian Yu is the recipient of the 2023 Cornelia Hahn Oberlander International Landscape Architecture Prize (“Oberlander Prize”).

Kongjian Yu was only 10 years old when he witnessed the power of nature firsthand. Heavy rain caused the creek near his village in China’s Zhejiang province to swell and spill over to the rice terraces. When he ran to the river’s edge in excitement, he slipped into the surging floodwaters. Fortunately, he was able to save himself by grabbing onto the willow and reed vegetation that grew all along the banks.

Almost all of China's medium and large cities are now susceptible to floods. And [Kongjian] Yu says 60% of them experience flooding every year. Extreme weather from climate change is exacerbating the problem.
