Cities – some thoughts on a Radiolab exploration

If you are a public radio junkie, and a science+art junkie, you’re probably already addicted to WNYC’s wonderful Radiolab podcast featuring Jad Abumarad and the incomparable Robert Krulwich. If you aren’t already addicted to this podcast… what are you waiting for? Point your browser thither right now, and thence find the appropriate link to download the podcast on your device of choice. Got it? Good.

Now, for this science+radio junkie with a lot of urban ecology on the mind, the Radiolab guys offered up the perfect trifecta recently, when they did a whole hour-long exploration of Cities!! I’ve been mulling it over ever since I heard it several months ago, wanting to write a lengthier blog post about it, but what with teaching, travel, and actually studying urban ecology, never seem to find the time. This episode was brought to mind afresh last week during a trip to Tempe, Arizona, while attending a very stimulating workshop on urban ecology and resilience (hosted by the good folks at the Stockholm Resilience Center). The workshop was a precursor to the 2011 Resilience conference, where I also presented some of our ongoing work on urban water policy, water use, and biodiversity in Fresno-Clovis. As we drove back midway through the conference, while crossing over from the Sonoran to the Mojave deserts, I subjected my sociologist friend and colleague Andrew Jones to this show – and figured I might as well share it here with you. I think it is a rather (typically for Radiolab) rich and unusual exploration of cities from different perspectives, and contains ideas I want to pursue further, some in writing here in time to come. Meanwhile, you can listen to the show right here, right now:



The parts that resonate the most with me are in the first several segments, on the comparative metabolism of cities. Could be in part because I am a sucker for comparative ecology and metabolic scaling, more so because I also happen to know Bob Levine, psychologist colleaage here at Fresno State, who shared some of his work on the geography of time with us during an evening at the Central Valley Café Scientifique several years ago. Having lived in a number of cities of various shapes, sizes, and cultures, I have experienced some of this variation in the pace of city life, of how we experience the flow of time in different places. So I can begin to see how cities shape our perception of time in interesting ways. What really intrigues me now, after listening to the show again, is this: do other animals (especially the ones with the sharper brains and cleverer minds like us) also perceive the flow of time differently in different cities? Does the flow of time — or, to put it in behavioral ecology terms: do the rates of certain behaviors and/or the overall time-budget — for a macaque in Bangalore differ from that of its cousins in Mysore or Papanasam? Does a Scrub Jay in Fresno hop or call or cache food at a higher rate than one in Visalia? Are the White-crowned sparrows wintering in Fresno singing at a slower rate than those in Phoenix or San Francisco? I think this calls for another participatory global citizen science project, just like Bob Levine and the Radiolab guys did with humans. I’m developing a comparable simple-but-robust metric and protocol that could be used with urban birds and mammals, and will share it once I’ve got it worked out. If you have any ideas or suggestions on how best to measure the flow of time in non-human animals, please do write to me. This may not amount to a whole lot of science – but I wonder…

On the economics and growing pains of farming and consuming organic foods

I had the radio on while on a prolonged cleaning mission at home yesterday afternoon (having run out of the usual podcasts I listen to under such circs). I had what seems like a small moment of cognitive disssonance when, while jumping back from, and then stomping out a nest of Black Widow spiders hiding behind a trashcan in a dark corner of the laundry room, I caught fragments of a conversation on the radio about earth- and biodiversity-friendly organic farming practices.

The show was a world of possibilities, something I hadn’t heard before on our local NPR station. The fragments of conversation I caught were interesting enough that I had to go look for the whole hour online. And it turned out to be an hour well-spent, as I think you may agree too. Its about the growing pains of organic farming, especially in the current economic recession.

The second half of the program is particularly interesting when two organic dairy farmer from Northern California are interviewed. Fascinating if (like us) you try to consume organic foods as much as possible (or as much as the wallet permits), and even more so if you dabble in organic farming. We’ve been enjoying quite a harvest of veggies from our own, and several neighbors’ urban backyard farms – which has definitely eased the pressure on our furloughed bank balance this summer.

The dairy farmers raise one important question in response to complaints about how expensive organic produce is: why do consumers never complain about the ridiculously high prices of the latest iPhone/Droid/Wii or other gadgets they line up to purchase on the first day, but don’t want to pay a buck or two extra for food they actually put in their bodies? In a country where conventional industrial farming has been subsidised heavily to keep supermarket prices low low low, it has become rather hard for us to imagine – and pay for – the real costs of farming organically. The same advertising driven marketplace that plies us with cheap unhealthy foods also mesmerizes us with the shiny tech baubles to the point where our family budgets have become strangely skewed, with food eaten at home – which should be the very core of our lives – taking up a mere 7% of our paychecks on average, which is less than half what we pay to drive around our farflung suburbs! Take a look at this graphic of where the average US household paycheck is spent:


The other interesting question to ponder (and hope about) is whether the recession is changing people’s priorities in ways that might actually lead to healthier eating! I raised a related question in my reconciliation ecology class when I last taught it two years ago, thus: will the recession encourage more people to start growing their own vegetables in their gardens? I think, tentatively, that we have the answer now in the growing urban farming movement around the US, with more and more people like us growing our own veggies, and more often organically than not. I think the scale problem of organic farming – that it doesn’t scale up very well when you think of the mass market – actually works in our favor here, because we are scaling down to small yards where it is easier, and cheaper, to grow a healthy crop organically.

The recession may also give us some pause before plonking down the credit card for the latest non-food consumer items or gadgets. Although mainstream economists do not like that because they tell us we have to keep buying stuff in order to keep the economy running and growing again! And the sales figures of the new iPhone 4 (for example) don’t suggest that such discretionary consumer spending is down all that much even now. But, if you do cut down on this part of your budget, is it likely that some of the savings may actually go towards healthier organic foods? After all, healthier eating should also lead to lower healthcare costs in the longer run. Is there any evidence that people are changing their spending patterns, especially on food, in this more rational direction? Or are our brains too irrational and too severely manipulated by advertising and farm subsidies to be swayed away from all the shiny and “cheap” unhealthy highly processed/industrial edible food-like substances (to borrow Michael Pollan’s phrase) filling the supermarket aisles and food courts of America?

I’ll stop rambling now and let you listen to the conversation on the show. Let me know what your thoughts are too.

Organic agriculture has grown up.  A once-marginal movement of plucky and slightly eccentric home gardeners has bloomed into mega-farms that ship around the world selling at premium prices.  In this program we’ll examine both ends of the organic industry food chain — a mid-size organic farming family and the world’s largest organic food retailer.  We’ll see what growing mainstream has done for – and to — organic farmers, and what remains to be done to give farmers and consumers the sustainable food system we urgently need.

Frans de Waal on the evolution of empathy

World-renowned primatologist FRANS DE WAAL has spent years studying chimpanzees, bonobos, and capuchins. While he has witnessed plenty of selfish and aggressive behavior, he has also watched primates cooperate, resolve conflicts, share food, laugh, and help each other. De Waal argues that these interactions show that empathy, altruism, and morality are hard-wired in the primate brain – including the human primate brain. This hour, Frans de Waal, Director of the Living Links Center at Emory University, talks about the evolution of empathy and what we can learn from primate cousins. His most recent book is The Age of Empathy: Nature’s Lessons for a Kinder Society.

This interview aired yesterday on Radio Times, from WHYY in Philadelphia. If the above embedded player doesn’t work for you, or you prefer to listen to the interview on the move, download the podcast here. And enjoy a thoughtful hour!

Building a Future as Green as the Past – a podcast with Dr. Michael Rosenzweig

For those of you who missed Prof. Rosenzweig’s talk on Reconciliation Ecology here in Fresno last week, I am working on posting an audio recording on the Darwin’s Bulldogs podcast soon. Meanwhile, here is a shorter version of his ideas in the form of an interview podcast from the University of Arizona, with accompanying slides, many of which we saw in the talk last week. Enjoy the interview, and share your thoughts.
