Ironic hypocrisy

For all of the teaching and research I do on sustainability…. living it, measuring it, valuing it…. I am occasionally a very poor example of it. In the past couple of weeks I have traveled to Scotland, Argentina, and Washington D.C.; ironically, those last two trips were meetings focused on the sustainability of carbon-neutral biofuels. Although I am very anxious about calculating my carbon footprint over these three trips (since I’d probably have to stop breathing for five years to get back to something close to carbon neutral), I am going to do it here as a form of very public shaming. I am hoping that it will motivate me to insist on more virtual trips…

Using this calculator, my total carbon footprint for the flights for these three trips was:

Houghton –> Scotland (measuring sustainable landscapes workshop) –> Houghton: 1.18 metric tons.

Houghton –> Argentina (Pan-American sustainable biofuels workshop) –> Houghton: 1.81 metric tons.

Houghton –> Washington, D.C. (NSF Sustainable Energy Pathways meeting) –> Houghton: 0.31 metric tons.

Total: 3.30 metric tons.

That’s roughly the same amount of carbon that a person in the Maldives emits PER YEAR. It would take roughly a hectare of forest a year to sequester the carbon from those three trips.


The new Pointillism

Brandon Martin-Anderson would have made Seurat proud; using US Census Bureau data (and a very large server), he recreated US and Canadian population patterns by representing each person as one dot.

What really struck me on this map is how the gridded road network in the Midwestern US dictates population settlement pattern, while natural features (such as the interior valleys in California) drive population settlement elsewhere. Of course major cities are obvious, but obvious too are the millions of people on the Florida coast who are at great risk of sea level rise from climate change (as well as more intense hurricanes).

What do you see?

Walking is so pedestrian

This recent article in Slate on the amount of walking that Americans do relative to those in other countries could not have been more timely for me (and thanks to Grist.com for bringing it to my attention!). I read it while in Newport, Rhode Island at a professional meeting (the US-International Association for Landscape Ecology, of all things) and it really struck a chord.

Always the cheapskate, I found a hotel that was almost one-third of the price of the hotel where the meeting was held, and it was only about a mile away: an easily walkable distance. I like to build these sorts of walks into my day, especially when I’m at a conference that involves a lot of sitting in dark rooms for hours on end. The morning walk ensures that I am awake for the presentations, and the evening walk allows me to reflect back on what I’ve learned.

However, although the walk looked straightforward and perfectly safe on the web, it was considerably less so in reality. At least a third of it involved walking in a grassy/sandy ditch while cars sped past on a two-lane road (and I was not the only walker using this route), and the rest of the way included narrow sidewalks littered with street signs, fire hydrants, and other impediments (I suppose I should include dog poop here as well). Marked and posted pedestrian crossings across two busy county roads were few and far between.

It seemed odd to me that a tourist-based town was so difficult for pedestrians, especially given that the town was settled far before automobiles were invented (some of the old houses in the historic district dated back to the 1700′s). Most likely, the space once devoted to pedestrians and horse-drawn carriages was given over to automobiles, with not much thought given to their inherent incompatibilities. Walkability is often emphasized in conversations regarding sustainable cities, and now I have a very personal understanding of this issue.
