Rural counties across middle America are turning paved roads back into gravel. The WSJ article is from 2010, and I wonder to what extent this trend has continued. I can’t say that it seems like much of a loss. I suspect that much of the rural pavement was laid down without a good understanding of how much O&M it was committing the local governments to paying for. As state and federal budgets shrink, and counties are left to pay for their own infrastructure, they realize that maybe cheaper gravel and lower speeds are actually a better value proposition.
David Montgomery‘s Dirt: The Erosion of Civilizations reminded me a lot of When the Rivers Run Dry by Fred Pearce, except that instead of looking at how we have allocated our water resources globally, it focuses on the way humanity has husbanded (or not) its soil resources throughout history, through a vast array of case studies in what we got wrong. It also reminded me a little bit of Energy at the Crossroads, insofar as the last chapter or two, instead of being a concrete, level-headed outline of what we need to do if we actually want to solve the problem which has been presented, it devolves a little bit into a lament. You’ve convinced me there’s a problem. Clearly you have some idea of what the solution looks like. Please don’t be afraid to put that idea into words, even if you think the plausible solutions are so far removed from our current way of doing things that someone is going to think you’re crazy. I think a lot of the most credible solutions to our sustainability problems sound “crazy” to “normal” people these days… but that’s just the way it is. We still need to know what the available solutions look like, or at the very least, what characteristics one can sketch out which any available solution has to have.
