Benefits of compact, car-free cities

Worldchanging

Tokyo Green Space examines the ecological and human benefit of reimagining cities with a focus on people and natural environments. I was interested to read a provocative article recently in Business Week entitles: “Cities: A Smart Alternative to Cars.”

The author Alex Steffen of Worldchanging argues that rebuilding cities into walkable places through in-fill and zoning changes might be more realistic and faster than the typical 16 year cycle to replace 90% of the United States automobile fleet. His definition of a new urban city is one in which daily driving is not a necessity and many people can live without private car ownership.

It is interesting that confronted with climate change, some hope that technological change will allow Americans to live as we have for the past thirty years with no change: zero emissions vehicles allowing for the same transportation patterns, and new building materials to permit the same massive housing structures. It’s analogous to finding a pharmaceutical cure for the effects of obesity without changing the foods we eat or the energy we exert.

The costs are staggering: transportation accounts for 25% of United States carbon, and 20% of that from personal transportation. There is also the environmental burden of manufacturing and disposal. I was surprised to learn that Americans spend more than 19% of household income on personal transportation, second only to housing.

Perhaps hardest for Americans to grasp is that denser, walkable cities can improve lifestyle compared to McMansions and suburbs. Well design buildings, smart infrastructure, and the community created through walking and biking could be a huge improvement to quality of life. Tokyo certainly exhibits many of the advantages of compact, transit-oriented cities where almost all daily activities are accessed by foot, transit and bike.

In addition to environmental and economic benefits, compact cities create more human interaction and community, improved public health from daily walking, and an opportunity to use public space currently devoted to vehicles for urban plants and wildlife.

Dystopian vision of Pacific Ocean in-fill

Seiwoo's Dystopian vision of Pacific Ocean in-fill

Seiwoooo’s Alban Mannisi, a landscape architect based in Tokyo, has created a future scenario dystopia in collage and narrative about the future of Saipan and the Pacific Ocean in 2048.

Mannisiimagines a world in which sustainability and massive waste create so much new reclaimed ocean land that Saipan becomes a hub of land traffic between Beijing, Tokyo and Osaka on one side, and Honolulu, Los Angeles and New York on the other.

The project’s aim is “to develop some critical views on the new trend of sustainability in urban planning and to stimulate the people involved to be more conscious of the possible outcomes that can be disastrous.”

Is this an antidote to the positive message of Tokyo’s Umi no Mori (or Sea Forest), or a worst-case dystopia?

I had the pleasure of meeting Mansini recently, and he shared these Tokyo and global urban architecture links with me:

-Funny weird Japanese architecture : Atelier bow Wow : Made in Tokyo
-Japanese landscape architecture company : Studio onsite
-An architect-Urban planner-Thinker and teacher at Waseda University  SOUHEI IMAMURA/atelier imamu
-The best Landscape Arch mind: James Corner
-Netherlands Urbanism Review : MONU
