Question: How can we make cities more sustainable?
Answer: 1. Sponge cities
Scientists think global warming is increasing the likelihood of extreme weather events, including floods. But some cities are fighting back, using the power of nature to mitigate the risks. In China, concrete neighbourhoods are being interlaced with green spaces that can naturally detain and filter water. The same concept is employed in Singapore, which has been dubbed “the garden city” due to its abundance of greenery.
2. Vertical forests
Short on space, people in cities have often looked upwards for places to expand. In Milan, Italy, architects have done the same with tree cover – creating a "vertical forest" on two residential tower blocks. Boasting 800 trees, 4,500 shrubs and 15,000 plants, the "forest" would cover an area the size of three and a half football pitches if planted on the ground. Similar projects are underway in cities in Switzerland, The Netherlands and China.
3. The 20-minute neighbourhood
Imagine if everything you needed for a happy, healthy life could be found within a 20-minute public transport trip, bike ride or walk from home. Some cities are working to make this a reality, with Melbourne leading the way – it wants residents to always be within easy reach of things like shops, business services, education or leisure facilities.
4. … and anything they can do!
In Paris, the mayor is using the Rue de Rivoli as a prototype for a future metropolis in which no Parisian should need to travel more than 15 minutes on foot or by bike to work, shop, or deal with a government agency.
