Desert Year: Call it Economic Development, but What’s in a Name?

by Skip Laitner • November 4, 2011 @ 9:06 am

John ‘Skip” Laitner is an economist, enjoying a desert year while on research sabbatical  from the American Council for an Energy-Efficient Economy. Skip is discovering some surprising insights from his time in the desert that can inform the way one looks at the economy and social systems. In a series of posts entitled Desert Year, Skip lends us his new insights, as well as his 40 years of experience as an energy and natural resource economist, to probe the economic, climate, and energy challenges that confront us.

I pulled up short, turning slowly onto a street that led through a private neighborhood. I thought I might walk perhaps 10 minutes before I resumed a slow jaunt.  As I crested a long hill I spotted a lean, weathered man in perhaps his early 70s who was out in his yard doing some chores.  He was just a few yards away and as I approach his driveway he commented, “I haven’t seen you around here before.” Which I took, from the slight tone in his voice, to be Western speak for, “You sure you belong in this neighborhood?”

“No,” I replied, “I live about a mile over. I’m just out on a run and thought I’d check out a new area.”  I grinned and waved at him, and kept moving on past.  Curiously, I also noted the street sign which read, “Via Amable.”  This seemed to be an amalgam of Latin and Spanish which I think translates into something like, “friendly path” or “friendly way.”  That translation seemed lost on my inquisitor. And then I got to wondering. . . what exactly is in a name?

There is another street I sometimes run past, “Sempre Verde,” which also appears to be a mixture of Latin and Spanish that roughly translates as “always green.”  Which is a curious thought for the Sonoran Desert.  Yes, plants like the Saguaro, the prickly pear cactus, and the Palo Verde (“green stick”) all have a bark or outer skin that is always green.  They’ve adapted to the combination of abundant  sunshine and a lack of water by integrating chlorophyll into their trunks.  This means is a form of greater efficiency as they have to rely less on their leaves to produce their food and energy.  But, as delightful as it is, I would hardly call the desert always green.

Desert Year: How Old is Old? How Big is Big?

As the monsoon season gently shifts into the fall, a second dry season for the flora and fauna of the Sonoran Desert begins. I was out wandering in the light of lingering afternoon sun, observing how the waxy leaves of the creosote bush reflect a pleasant hue of green, when I stopped to admire a particularly nice bush.  I looked around and quickly realized that in this part of the desert I was surrounded by a lot of creosote bushes. As I walked up to that first bush and caressed its leaves, I began to wonder how old that particular bush might actually be.

It turns out that all of the plants that I was looking at on that glorious autumn day were likely genetically identical clones of a single original bush.  Saguaros and the Foothill Paloverdes are known to live for 200 years or more.  One famous Creosote Bush in the Mojave Desert, known affectionately as the King Clone, is thought to be 11,700 years old. It is considered one of the oldest living organisms on Earth.  Even some species of desert lizards are clones.  Sonoran Spotted Whiptail lizards are all parthenogenic females. I wondered  if this reptilic sisterhood might collectively be the desert’s oldest lizard.

The mind then wanders in some mysterious way and for some reason I thought of a recent news story about the Arctic Ocean’s outer continental shelf. The federal government estimates the oil and natural gas reserves there to be 26.6 billion barrels of recoverable oil and 130 trillion cubic feet of natural gas.  Assuming that these resources can be safely and inexpensively produced, that could produce a lot of energy. But how big is that? (more…)

Desert Year: More by Waste than Ingenuity?

In the Sonoran Desert the bizarre is very real.  The heat of the sun and the harshness of the environment have forged an amazing assortment of wonderfully complex and adaptive life forms. 

The jumping cholla, or teddy bear cholla, resembles a cuddly plant with soft arms which, as you look closer, are completely covered with golden and silvery spines that seem to jump off the plant at the slightest touch.  Ouch! And there are the javelinas that, yes, look like wild pigs but which are actually members of the peccary family, a group of hooved mammals originating not in Eurasia but in South America.  And, of course, there is Boojum tree which must be among the most strange spiny upside down carrots most people have never seen.

Yes, there are some very strange things to be seen wandering out on the desert floor.  But there is also a collection of very strange sights that tug at my mind – strange not because they’ve assumed a curious shape, but because they are so surprisingly common and so out of place: a couple of orange peels, or empty water bottles, streams of paper fragments, an old mattress, and of all things, a used condom hanging off the branch of a creosote bush. 

From time to time, the sight of these many and clearly out-of-place things do get me to wondering.  And I forced to conclude that our standard of living may be more the result of our garbage and trash than our vaunted Yankee ingenuity. (more…)
