bike transportation in the news

This year's high gas prices have inspired more than just me to reduce car trips in favor of the bicycle. Indeed, newbie bike commuting has become something of a hot media story. The following is a quick sampling:
  • At Slate.com, Bill Gifford writes about the joys, but also the frustrations and lessons learned, of trying to go completely auto-free in his exurban East Coast home. The bottom line seems to be that cycling-for-transportation is a very different task than cycling-for-recreation, and those who go from the latter to the former (such as myself) have some adjustments to make. Most importantly, while it seems that recreational cycling knows almost no bounds and is an activity you can completely immerse yourself in, transportational cycling has its limits.
  • Also at Slate.com, Andy Bowers is the latest to challenge the conventional wisdom that "Nobody Bikes in L.A." Like Gifford, Bowers describes in some detail how subversive/transgressive an act urban cycling can seem, which is both part of its appeal and much of its challenge. Unlike Gifford, though, Bowers' bottom line is very upbeat, revelling in how he, thanks to the bike, had "discovered a different Los Angeles." Bowers doesn't go so far as to pronounce the conventional wisdom wrong and claim that LA is actually a pretty bike-friendly place, but he provides a welcome corrective to the LA- and bike-bashing likes of the Times of London's Chris Ayres.
  • Finally, in the December 2000 issue of Bicycling magazine, Dan Koeppel writes about the "Invisible Riders" who bike-commute not by choice but out of economic necessity. Specifically, he profiles the countless, mostly Spanish-speaking immigrant population of day laborers who every morning converge on employment centers such as Harbor Park. It's a fascinating story that reveals a population of cyclists who are totally anonymous and disconnected from the much more affluent (and White) world of recreational cyclists such as myself. This is quite simply one of the best articles I've read, in any publication on any topic, in a long time.

cyclocross (and bike commuting)

Perhaps needing to boost my masculine pride as I spent a long spring and summer watching a parade of other men remodel my house, I gradually began acquiring the pieces to a new bike, which I managed to put together all by my male self in September. Since then I've enthusiastically embraced two new cycling worlds with my new bike (a Giant TCX frame with an eclectic mix of mostly-used Ultegra-level parts taken off my now-upgraded road racer): cyclocross and bike commuting. Never in my wildest imagination did I think I'd take my riding off road, at all, when I returned to cycling three years ago. But the more I rode and the more I read about 'cross--and the more I got sick of driving back and forth to work--the more this old-school, Euro-style hybrid mix of on- and off-road cycling beckoned. And I can enthusiastically say I'm hooked and never turning back. A light (fast) but comfy 'cross bike is ideal for riding around city streets with a bag of books, papers, and clothes on your back. (The ubiquitous mountain bike is the SUV of the two-wheeled world: inefficiently overengineered for the paved world in which the vast majority of their owners use them.) With my new ride, I'm now bike-commuting 3 to 4 days a week. The two-a-day one-hour rides, which usually contain an unstructured mix of hard and easy efforts, are proving to be some of the most fun and effective off-season riding I've ever done. Beside being a gasoline (and thus money) saver, the commuting rides are allowing me to spend far more off-season time on the bike than I've been able to manage in the past--while still allowing plenty of time with my family, especially on weekday mornings. And psychologically, the commute rides do wonders to energize me ahead of my long teaching days, while at the same time getting me appropriately excited about next year's road-racing season. The only downside is I resent driving to work--on rainy days and on my Monday rest days--more than ever. The real reason I put together the new bike, though, was to try out cyclocross. This is a test-the-water 'cross season for me, with little or nothing in the way of targeted training or practice. Green as can be, I entered my first 'cross race down in Harbor City a couple of weeks ago (October 30), and had an absolute blast. And I'm heading out again this Sunday to the race in Palos Verdes. For those unfamiliar with the sport, it's a hybrid of road racing and cross-country mountain biking that is run on courses that mix pavement, gravel, grass, mud, and "single-track" rocky trails. The riding is not as technical as mountain biking, but the field gets strung out more like a cross-country (running or mountain biking) race than the peleton-centered world of road racing. The bikes themselves are a hybrid: essentially road machines fitted with knobby off-road tires and the mountain-style brakes to fit around these fatter tires. The defining feature of 'cross, though, is the presence of steep run-ups and short barriers that require riders to occasionally dismount and carry their bikes a short distance before remounting and pedaling on. I'm still a long way from being fit and skilled enough to be as competitive in the races as I would like--maybe next year--but man is it fun. And 'cross also has the added attraction of being more spectator friendly since the winding courses across open fields can often be seen from a single vantage point and since the riders aren't so anonymously whizzing by each lap in crowded group. This also means that 'cross is relatively photogenic, and sure enough, my first race produced far and away the two best photos anyone has ever taken of me in a bike race (thanks to Mitch Clinton's excellent work): For more on the unique subculture of cyclocross, check out the following:

global demographics

This has little or nothing to do with bicycles, soccer, urban studies, or any of my other usual topics for this blog. But it's been a month since I posted anything, and I had written this up for my Human Geography students anyway, so I thought I'd might as well share with all. Specifically, this is a summary of some of the more interesting and significant points that I found in the United Nations' most recent "World Population Prospects" report.

World population growth is expected to continue until at least 2050, but fertility rates (and thus growth rates) are declining fast and population growth is thus slowing down. Nonetheless, our population of 6.5 billion today is expected to be approximately 9 billion in 2050, with virtually all of this growth occurring in less-developed countries. Indeed, the fastest growth is happening in the 50 or so “least” developed countries, which are primarily located in Sub-Saharan Africa. This growth is driven by traditionally high fertility rates, which more than offset the fact that death rates are actually rising in many of these countries due primarily to the HIV/AIDS epidemic, which infects as many as 20, even 30, percent of the people in some places.

We, in fact, are in the middle of a century (1950-2050) of astounding population growth on a global scale, with (again) that growth primarily happening in the less-developed regions of Africa, Asia, and Latin America. Note, for example, the changing roster--and their corresponding populations--of the twenty largest countries (defined by present-day boundaries) in the world.

This population growth is of course fuelled by high fertility rates. Indeed, the UN estimates that as many as five different countries still have a fertility rate of more than seven: Niger (7.9), East Timor (7.8), Afghanistan (7.5), Guinea-Bissau (7.1), and Uganda (7.1). Needless to say, there are many others--primarily in Sub-Saharan Africa--that have fertility rates above six. The good news, at least if you’re concerned about rapid population growth, is that fertility rates are expected to decline dramatically, so that by 2050, all countries will be well below four. Specifically, Niger is expected to remain at the top, but with a rate of just 3.6, more or less the same rate as existed at the peak of our 1950s-centered Baby Boom here in the United States.

While population growth will remain the primary global story well into the future, many regions and countries face a rather different demographic challenge: population decline. Fertility rates have dropped well below the replacement rate in several countries, primarily in Europe but Japan and South Korea as well. Add declining life expectancies (higher death rates) in much of post-Soviet eastern Europe, and the expected population decline is shocking. Between 2005 and 2050, for example, Russia is expected to lose 31 million people, a full 22% of its current population. Even more dramatic is Ukraine, whose expected population loss of 20 million amounts to 43% of its current population. Yikes! Other countries expected to lose at least three million people during the next 45 years are Japan (16 million); Italy and Poland (7 million each); Germany (4 million); and South Korea, Belarus, and Bulgaria (3 million each). While their absolute losses won’t be as great, a number of additional eastern European countries are also expected to lose at least 20% of their population; they include Lithuania, Latvia, Romania, Moldova, and Georgia.

These slow-growth and negative-growth countries in Europe already have some of the oldest populations in human history. Indeed, the ten oldest populations in the world all have a median age between 40 and 43 years. In order, they are: Japan, Italy, Germany, Finland, Switzerland, Belgium, Croatia, Austria, Bulgaria, and Slovenia. And most of these countries are expected to get older still. South Korea, for example, is expected to have a median age of 54 (!) in 2050, with Italy (53) and Japan (52) and several others close behind. Imagine living in a country where more than half the people are over age 50. You think the AARP is a powerful political lobbying force today; as they say, you ain’t seen nothin’ yet.

Actually, the USA has a remarkably young population compared to our European and East Asian peers. Our median age today is a sprightly 36--which is rather depressing for me since it places me, albeit just barely, among the older half of Americans--and in 2050, half our population will remain under the age of 41. Still, that’s a far cry from most Sub-Saharan African countries today, where the median age--get this--is only 16! (And in Uganda, the median age is under 15.) Think about it, that’s an entire region of the world where most of the people alive today were born after the Berlin Wall fell down and the Soviet Union began to fracture apart, and the only U.S. Presidents they have ever known are named Bush or Clinton.

While China and India are infamous for sex-selective abortions (or even infanticides), with families purposefully choosing to raise boys rather than girls, they are not the most gender-unbalanced countries on the planet. They do indeed have more males than females (106 males for every 100 females in China, 105:100 in India), but that is nowhere near the imbalance seen in a few other countries--most of them on the Arabian peninsula. For every 100 females in their respective countries, there are 117 males in Saudi Arabia, 128 males in Oman, 132 males in Bahrain, 150 males in Kuwait, and a whopping 206 males in Qatar. But that isn’t even the top of the list, as the UAE checks in with 214 males for every 100 females. Why? Well, these traditional societies certainly have their share of gender-discriminating practices, but the real issue here is migrant labor. All of these oil- and construction- focused economies are home to millions of male immigrant workers, primarily from South Asia. Indeed, while it makes sense to describe the UAE as an “Arab” country--that’s what the “A” stands for after all--most of the people (men) who live there are of South Asian origin (India, Pakistan, etc.).

On the other end of the spectrum are countries--mostly in eastern Europe--where women outnumber men, in large part because old and not-so-old men there have been dying at alarming rates while relatively few boys (or girls) are being born to replace them. Indeed, the seven lowest male-to-female ratios in the world are all former republics of the Soviet Union: Latvia (84 males per 100 females); Estonia and Ukraine (85); Armenia, Lithuania, and Russia (87); and Belarus (88). The United States, in comparison, is a more balanced place, with 97 males for every 100 females--women outnumbering men by a small degree simply because they tend to live longer, by about a decade on average.

Finally, one last quick note regarding migration. There presently is an average annual net migration of 2.5 million people from LDCs to MDCs. The two largest out-migrating regions are Asia (1.2 million) and Latin America (700k). The two largest centers of net in-migration are North America (1.3 million) and Europe (900k). It is thus no accident that the two fastest-growing Census Bureau categories in the United States are "Hispanic" and "Asian-Pacific Islander".
