In the most recent issue of Orion, James Howard Kunstler restates his prescription for an oil-scarce future: reinvesting in rail and water transportation; re-localized economies; and urban densification.
"The widespread wish persists that some combination of alternative fuels will rescue us from this oil and gas predicament and allow us to continue enjoying by some other means what Vice-President Cheney has called the "non-negotiable" American way of life. The truth is that no combination of alternative fuels or systems for using them will allow us to continue running America, or even a substantial fraction of it, the way we have been.
The key to understanding the challenge we face is admitting that we have to comprehensively make other arrangements for all the normal activities of everyday life...In general, the circumstances we face with energy and climate change will require us to live much more locally, probably profoundly and intensely so. We have to grow more of our food locally, on a smaller scale than we do now, with fewer artificial "inputs," and probably with more human and animal labor. Farming may come closer to the center of our national economic life than it has been within the memory of anyone alive now. These changes are also likely to revive a menu of social and class conflicts that we also thought we had left behind.
...We have to inhabit the terrain of North America differently, meaning a return to traditional cities, towns, neighborhoods, and a productive rural landscape that is more than just strictly scenic or recreational. We will probably see a reversal of the two-hundred-year-long trend of people moving from the country and small towns to the big cities. In fact, our big cities will probably contract substantially, even while they re-densify at their centers and along their waterfronts. The work of the New Urbanists will be crucial in rebuilding human habitats that have a future. Their achievement so far has been not so much in building 'new towns' like Seaside, Florida, or Kentlands, Maryland, but in retrieving a body of knowledge, principle, and methodology for urban design that had been thrown away in our mad effort to build the drive-in suburbs."
