Discussion Overview

The discussion revolves around the potential for rebuilding New Orleans in a sustainable manner following significant environmental challenges. Participants explore various ideas related to urban planning, renewable energy, and the feasibility of raising the city's elevation to combat future risks from sea level rise and natural disasters.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants propose that rebuilding New Orleans presents a unique opportunity for sustainability, suggesting the city could become a model for environmentally friendly urban design.
  • Others argue against the practicality of raising the city’s elevation significantly, citing the immense volume of material required and questioning the feasibility of such an undertaking.
  • A few participants express skepticism about the motivations behind rebuilding, questioning whether it is wise to rebuild in the same location given the risk of future disasters.
  • Some suggest that if rebuilding occurs, it should incorporate renewable energy solutions and compact urban designs to enhance sustainability.
  • There are concerns raised about the lack of widespread ideological support for significant changes, with some participants doubting that a movement towards sustainable rebuilding can gain traction.
  • One participant suggests a more practical approach, advocating for raising certain buildings while maintaining open spaces for parks and wetlands in lower areas.

Areas of Agreement / Disagreement

Participants express a range of views on the feasibility and desirability of rebuilding New Orleans sustainably. There is no consensus on the best approach, with multiple competing perspectives on the practicality of the proposed ideas and the overall necessity of rebuilding in the same location.

Contextual Notes

Participants highlight various assumptions regarding geological conditions, the scale of proposed changes, and the societal willingness to embrace sustainable practices. The discussion reflects uncertainty about the implications of climate change and the potential for community mobilization around environmental issues.

This is a unique opportunity to rebuild a city for sustainability.

Here is an excellent http://openexchange.org/features/register.html with some great ideas.

It's useless, it's so out of touch. Take their #1 point for example:

1.) Raise the level of New Orleans wherever possible simply by adding fill and building on top of that. Calculate sea level rise caused by global warming over a few more decades and add another ten feet of fill.
 
I'm leaning towards the idea of rebuilding... but jesus christ this guy is insane. The UN actually gives consideration to this organization!??!?

4.) Establish a crash program for renewable energy like solar and wind, optimal with the energy-conserving structure of the city rebuilt in the compact, mixed-use pattern.

Because compact, small areas are beautifully suited for solar power...
 
Why should they rebuild? What happens when it gets hit again?

If they will, they should at least move it to somewhere safe.

When some city in Hawaii got hit by that tsunami or tidal wave, they DID rebuild, because it was a moneymaking city, and lots of people who lived there were in love with it, but they rebuilt it farther off shore, to avoid future risk.

I guess I missed your point.

Could you elaborate?

You are confusing the point. Small compact means people can get around without automobiles.

I agree, it is a bad place for a city. The reality however is that it will be rebuilt. Since it is a foregone conclusion that New Orleans will be rebuilt, right where it is at, I would like to see it rebuiult as the greenest most efficient city in the world.

We have the opportunity to make it something special, a model for sustainable environmentally friendly cities.

I think what he/she means is that the people have no idea what they are talking about! They want to raise a whole city by filling x meters3 with concrete or cement or earth? New Orleans was about 907.0 km², the article suggests more than 20 ft., = ~6 m, coming out to 5,442 km3. Usually when that much Earth is formed, its from a supervolcano, La Garita Caldera, Colorado, United States spewed over 5,000 km³ of lava, decimating any life in its path. The Earth sure is eco-friendly.

The most recent supervolcano to erupt (~4000 yrs. ago), was at Lake Toba, Sumatra, Indonesia (2,800 km³), aka the Toba catastrophe. The eruption at Lake Toba plunged the world into a volcanic winter -- the same thing that would happen from an asteroid impact or if all the nuclear weapons were set off at this instant -- and is thought to be responsible for the incredible bottleneck in the human population (~4000 yrs. ago), a near extinction.

By comparision to all these thousands of cubic kilometers, the Mt. St. Helens eruption of 1980 ejected less than 1 km³

I would laugh at anyone who thinks it will happen, to New Orleans. Sure some people would like it to happen but, we are not at a point in any widespread ideological movement at which something like that would happen.

I did not agree with the entire article and I don't think it is practical given the geologic conditions of the area.

They were not suggesting we raise the entire area, just some parts where it may be feasible. Personally I would raise all buildings up a few stories and have parking garages or other non living spaces etc. below them. Spread the buildings out with raised walkways in between and lots of open space in the low lying areas for parks wetlands etc.

A movement doesn't happen overnight. It has to start somewhere and grow. Just because the people in this country are fed disinformation about the environment doesn't change the fact that global warming is happening.
