Sustainability Science
How might we keep the lights on, water flowing, and natural world vaguely intact? It starts with grabbing innovative ideas/examples to help kick down our limits and inspire a more sustainable world. We implement with rigorous science backed by hard data.

Bamboo could help developing cities urbanize

Bamboo could help developing cities urbanize | Sustainability Science | Scoop.it

What if there were a local, renewable material that could be used instead of steel in reinforced-concrete buildings? And what if that substitute could be manufactured easily? These questions have motivated Dirk Hebel, an assistant professor of architecture and construction at the Future Cities Laboratory, in Singapore, to investigate a bamboo fiber composite as a possible substitute for steel reinforcement in concrete. The Future Cities Laboratory is a research arm of ETH (Eidgenössische Technische Hochschule) Zürich, in Switzerland, and is the first program under the newly formed Singapore-ETH Centre for Global Environmental Sustainability, which conducts multidisciplinary research to foster urbanization that conforms to the principles of sustainable development.

PIRatE Lab's insight:

There are many "ifs" here, but this is an intriguing approach that may avoid the pitfalls of previous attempts at using bamboo for such a strengthening role in buildings.  I suspect that this won't work, and am always worried when press releases go out before a project has even preliminary results, but I very much like the innovative and new idea-type approach these folks are taking here.

Looking at purchasing a house in the next year or so and this is one thing we have been looking at. Although we don't want to raise our own meat we would like to grow everything else we eat.

Good visual representation of what it would take to be self sufficient.

If you need a backyard that is about 2 acres to live off the land imagine how big of a backyard you would need if you had a family of 8.

Transportation and Planning

"When you combine a street and a road, you get a STROAD, one of the most dangerous and unproductive human environments. To get more for our transportation dollar, America needs an active policy of converting STROADs to productive streets or high capacity roadways."

In this video, a road provides high connectivity between places, and a street is a diverse platform of social interactions that create a place.  A 'stroad' can be likened unto a spork--it tries to do it everything but does nothing especially well.  While you may debate the principle being shown, this video (found on Atlantic Cities) is a good way to show the spatial thinking that city planners need to utilize to improve the urban environment.

the danger of stroads

François Lanthier's curator insight, January 31, 2:19 PM

The Stroad - an unfortunate phenomenon... NYC is taking action to minimize its' STROADS... more cities should do the same.
