How can we design flood-resistant cities?

From rising sea ranges in Mumbai to insufferable warmth in Houston, cities all over the world are feeling the results of local weather change. Sadly, they don’t at all times have the proper infrastructure to deal with its impacts — which is one cause why cities are starting to reimagine city design.

Dozens of city areas are experimenting with “spongey” infrastructure as a potential resolution. It goes by completely different names all over the world, however all of them comply with the same design philosophy: take away current pipes and drains to handle rain and stormwater, and implement pure infrastructure like rain gardens and vegetation to soak up water as a substitute. The outcome? Lush, inexperienced, rainforests towards the backdrop of dense city areas. These designs are usually not solely nice for managing city flooding, however in addition they help biodiversity — which is one among our strongest instruments within the battle towards local weather change.

Within the video above, we check out sponge metropolis designs all over the world and clarify how they work. Plus, city wildlife ecology and conservation researcher Charlie Nilon explains why biodiversity is crucial to city areas, and the way pure infrastructure tasks, like sponge cities, can assist make our concrete jungles wealthy with plant and animal species.
