What is a 'sponge city,' and how does its design aim to address the impacts of climate change?

A 'sponge city' uses natural infrastructure like gardens and trees to absorb excess water, improving drainage, preventing floods, and creating diverse biological environments to combat climate change effects.

Describe one way ancient Chinese cities handled water effectively and how this practice is being used today.

Ancient Chinese cities used sloped eaves to direct rainwater to permeable pavements and lined walls with vegetation to absorb stormwater. Today, this is seen in the reimplementation of permeable pavements and urban gardens.

What are some limitations of sponge cities in preventing damage from natural disasters?

Sponge cities can only absorb a limited amount of excess water, and their effectiveness varies depending on local climate, hydrology, and socio-economics. They can also be expensive and require a lot of space.

Give an example of how cities in the United States are adapting existing green spaces to function similarly to sponge cities.

Cities like Los Angeles and Boston are planting vegetation on curbs and creating green spaces along median strips to increase water absorption.

How China is designing flood-resistant cities

Guided Notes

3 key concepts

1
Sponge cities use natural infrastructure, like urban parks and native trees, to help cities combat and withstand a changing climate.
2
Urbanization can lead to habitat losses that put some species in danger, but cities can conserve biodiversity by creating environments where nature can flourish and soak up excess water.
3
China's sponge city pilot program aimed to improve urban drainage and flood prevention by supplementing grey infrastructure with natural solutions like gardens and permeable pavement.
