How to Build Cities for Wildlife, Not Just People – New Research

In central Seoul, South Korea, a motorway once covered a buried urban stream. Today, that same stretch has been uncovered – a process known as daylighting – and this river is home to plants, fish and insects. This flowing water cools the city in summer and attracts tens of thousands of people every day. What used to be concrete now boosts biodiversity, the local economy and community wellbeing.

Similar transformations are unfolding elsewhere.

In Christchurch, New Zealand, river habitats and wetlands were rebuilt after a major earthquake in 2011, guided in part by Māori knowledge of waterways and floodplains. In Vancouver, Canada, nature-based stormwater systems have been integrated into urban design through long-term collaboration with local First Nations.

Across the world, urban planning projects are beginning to take a different approach. One that designs with living freshwater systems, rather than trying to control and contain them.
