Does urbanization in America explain the declining deaths by lightning strike?

Posted on by

Here is an interesting research question: is urbanization responsible for the sharp decline in Americans who die by lightning strike each year?

In the lightning-death literature, one explanation has gained prominence: urbanization. Lightning death rates have declined in step with the rural population, and rural lightning deaths make up a far smaller percent of all lightning deaths. Urban areas afford more protection from lightning. Ergo, urbanization has helped make people safer from lightning. Here’s a graph showing this, neat and clean:

And a competing perspective:

I spoke with Ronald Holle, a meteorologist who studies lightning deaths, and he agreed that modernization played a significant role. “Absolutely,” he said. Better infrastructure in rural areas—not just improvements to homes and buildings, but improvements to farming equipment too has—made rural regions safer today than they were in the past. Urbanization seems to explain some of the decline, but not all of it.

“Rural activities back then were primarily agriculture, and what we call labor-intensive manual agriculture. Back then, my family—my grandfather and his father before that in Indiana—had a team of horses, and it took them all day to do a 20-acre field.” Today, a similar farmer would be inside a fully-enclosed metal-topped vehicle, which offers excellent lightning protection. Agriculture has declined as a percent of total lightning-death-related activities, as the graph below shows, but unfortunately it does not show the per capita lightning-death rate of people engaged in agriculture.

Sounds like more data is needed! I wonder how long it would take to collect the relevant information versus the payoff of the findings…

More broadly, this hints at how human interactions with nature has changed, even in relatively recent times: we are more insulated from the effects of weather and nature. During the recent cold snap in the area, I was reminded of an idea I had a few years ago to explain why so many adults seem to talk about the weather. Could it be related to the fact that the weather is perhaps the most notable thing on a daily basis that is outside of our control? As 21st century humans, we control a lot that is in front of us (or at least we think we do) but can do little about what the conditions will be like outside. We have more choices than ever about how to respond but it prompts responses from everyone, from the poor to the wealthy, the aged to the young.

Mapping the boundaries of the Midwest

Posted on by

Mapping the Midwest has now become a crowdsourced project through asking “What’s the Midwest to you?”

That’s the question design and planning firm Sasaki Associates is asking visitors to its new exhibit, “Reinvention in the Urban Midwest,” which opens at the Boston Society of Architects (BSA) Space this week. The project includes an interactive survey that contains a timeless challenge: Draw the geographic boundaries of what counts as the U.S. Midwest…

Judging by the maps drawn by others and myself, it appears Montana, Wyoming, Colorado, Kentucky, Arkansas, and Oklahoma are the states of most contention. I personally felt I had no choice but to cut some of them in half. Perhaps the correct answer is still the textbook answer: the states of most intensified yellow (at least as identified by those who’ve lived in the Midwest the longest) make up the U.S. Census Bureau’s definition of the Midwest: Illinois, Indiana, Michigan, Ohio and Wisconsin to the east, plus Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota to the west.  (As a commenter pointed out, cartographer and historian Bill Rankin has also done a Midwest mapping project, in which he overlaid 100 different maps of the Midwest and made the confounding observation that  “no area that was included on every single map”.)

So the geographic boundaries of what most Americans consider the Midwest aren’t exactly clear, but Sasaki has also included another set of maps that reveal a much less murky truth: the Midwest has urbanized in a vastly different way from the rest of the United States. The graphic below maps out the population densities found in urban areas from four U.S. regions in 2010 (a darker shade signifies a larger, denser population)…

The Midwest is characterized by small but strong urban centers that transition sharply to rural surroundings. This pattern has of course grown from the region’s historical focus on agricultural land use. Sasaki’s recent work in Iowa suggests a continued population decline in rural areas but growing population density in more urban areas. However, the growth of urban areas in the Midwest is not uniform. The firm has further identified that agricultural cities in the plains sub-region, such as Des Moines, Iowa, or Lincoln, Nebraska, are indeed growing due to factors like de-ruralization and in-migration to city centers, while traditionally heavy-industry cities in the forest sub-region, such as Milwaukee or St. Louis, are still losing population.

One takeaway: the Midwest is a fuzzily-defined entity that perhaps has more to do with perceptions and culture than it does with exact geography. This would be aided by then asking people who drew the maps to then type in words they associate with the Midwest. I like the contrasting maps between those who have spent more of their lives in the Midwest versus those who have not: there are some clear differences.

The connection between farmland and cities is a good catch. Big cities like Chicago or Omaha were (and still are) intimately connected to agricultural commodities that needed to be distributed and sold through the big cities. For example, if you look at the early railroad construction in the Chicago region, much of it was linked to shipping products from the plains, everything from wheat (southwestern Wisconsin) to lead (Galena) to then distribute further east. Or look at the trading of commodities in places like Chicago and the creation of new kinds of markets. Even though there are big gaps between the Chicago area and the rest of Illinois – they operate as very different worlds – both would strongly consider themselves part of the same region, even if they can’t speak to the deeper ties that connect them.

Trying to hold a county fair in suburban DuPage County

Posted on by

DuPage County now has over 915,000 people and has little open land left for development. Amidst rapid suburbanization after World War II, there has always been a DuPage County Fair. Now, there is public debate about whether it makes sense to continue having this event:

The DuPage County Board should examine the long-term viability of its county fair and how distribution of state funding for the event is handled, a consultant has recommended.

And if the fair continues, the county should consider a new location, even if it means sharing a site with another county, the consultant recommends…

The fair, held each July on county-owned land in Wheaton east of DuPage’s government center, is run by a nonprofit association that relies heavily on funding that is funneled from the state Department of Agriculture through the Fair and Exposition Authority. Transferring that responsibility to the County Board would remove a layer of government by in effect eliminating the need for the seven-member fair authority, and that would “relieve the county of any associated risk,” the firm said.

Crowe Horwath pointed to decreased funding from the state and declining fair attendance as reasons why the county should consider whether the fair makes sense at all in the long run. The fair received an average of $300,000 a year in 2005-07. The figure in 2011 was about $198,000. The firm also noted that the fairgrounds are valuable property for which a better use might be found. The fair leases the land for $1,375 a year.

It is not surprising that this discussion has arisen in an era of fiscal issues at multiple levels of government.

The best argument I could imagine for the fair is that it is a reminder of what DuPage County once was. For the first 100 years of its history, DuPage County was primarily farmland and small towns that were within the orbit of Chicago. Produce from the farms could be shipped by rail or road to Chicago, destined for eastern markets through the Great Lakes, or to the southwest, eventually bound for the Mississippi River and points due south. One farm in the county even became the focus of a television show during the early 1950s:

In the spring of 1953, the Illinois Depart­ment of Agriculture began a search for a farm and a farm family who would become the stars of a new television show on the National Broadcasting Company. One of the thirty-five farms on the itinerary was the Harbecke Farm on Gary Avenue, rural Cloverdale in Bloom­ingdale Township, operated by Harbecke’s daughter and son-in-law, Bertha and Wilbert Landmeier. Tracing their roots to pioneer German farm families, the young couple had moved to the Harbecke Farm to operate a dairy farm. They had recently installed dairy equip­ment which carried the milk in refrigerated tubes from the milking machine to cooling tanks on the milk truck, which transported the commodity to an Addison dairy. The farm also had a hay drier which was another piece of modern machinery not found on every farm in  1953. These advantages, plus the fact that the location was considered one of the best be­tween Chicago and the Fox River for beaming the television waves, made the selection of the Harbecke-Landmeier Farm ideal for the show.

Thus, “Out on the Farm” began the first of a two-year run from the Harbecke-Landmeier Farm in the summer of 1953.  During the second season the first outdoor network colorcast originating from Chicago was the pickup from the Landmeier Farm. At the end of the 1954 season, the show was over, as Cloverdale and all of DuPage County were due for rapid change.

Here is a short description of the transformation from farmland to urban county:

The DuPage County Fair is the only county fair in Illinois located in a completely urban setting. Historical research showed that when the first DuPage County Fair was held in 1955, the county was 85% farmland. By 2000, the last farm vanished as DuPage County was absorbed into Chicago’s urban sprawl.

Today, the only farms DuPage County residents are likely to know about are Forest Preserve properties such as Kline Creek Farm in West Chicago or St. John’s Farm in Warrenville.

In the end, it sounds like it will be difficult to reserve valuable land for a week of nostalgia and history every year.

Growing interest in the investment potential of farmland

Posted on by

With people looking for good investments, farmland is getting some attention:

Just how hot is American farmland? By some accounts the value of farmland is up 20% this year alone. That’s better than stocks or gold. During the past two decades, owning farmland would have produced an annual return of nearly 11%, according to Hancock Agricultural Investment Group. And that covers a time period when tech stocks boomed and crashed, and housing boomed and crashed. So at a time when investors are still looking for safety, farmland is becoming the “it” investment.

The article goes on to say that because food demand is up, particularly for corn, and crop yields are up because of improved technology. At the same time, perhaps there is a market bubble going on here and it is difficult to get into the business of owning farmland.

I find it interesting that there is no mention of land development in all of this. In areas of sprawl, farmers can benefit from skyrocketing land prices as developers and builders look to acquire buildable acreage. But this story seems to be talking mainly about farm land in the middle of country, not farmland on the booming southwest edge of the Chicago region. In the long term, is farmland more valuable because of the commodity values (which can fluctuate) or because it can eventually be sold for other profitable uses?

Perhaps this all works because it is difficult to envision too much more American land becoming farmland – the total number of cropland (and farmland and pasture) acres has dropped from over 445 million acres in 1997 to over 406 million acres in 2007. If food demand is continually strong and there is a somewhat fixed number of acres that can be farmed, perhaps this is indeed valuable land.

Basic sociological question: “what does civilization as we know it rely on?”

Posted on by

Big questions about society can be great for Introduction to Sociology courses. Here is are the sorts of questions that I think could work quite well:

So, what sort of machines do you need to create an industrial civilization—kind of like the ones we have now, but more sensibly sourced. I remember taking a sociology course years ago where we started out with a similar question, although we conceived the question more broadly—what does civilization as we know it rely on? The answer then (decades ago, before the impact of The Whole Earth Catalog had been felt) was something along the lines of “technology.” But this is a much better question.

If we stuck with the second question here, “what does civilization as we know it rely on?”, I could imagine a class could generate a lot of answers:

1. The Internet. In the vast scope of human history, this may seem silly. But for people raised in the Internet era, it would be pretty hard to imagine life without it.

2. Electricity. This makes all sorts of things possible.

3. The steam engine. This helped give rise to the Industrial Revolution.

And so on. But these are all technological changes that could go back to the plow and the wheel and illustrate the human capacity to create and utilize tools. We just happen to live in an era where such technological change is rapid and our daily lives are full of machines. But what about more cultural or sociological phenomena?

1. Language. The ability to communicate in formalized ways gave rise to oral traditions, writing, etc.

2. Government. This doesn’t necessarily have to mean the big bureaucracies of today that impressed Max Weber. But just a form of ruling or authority that helped bring about communities.

3. Sustained agriculture. This has been the traditional answer to how humans were able to create more complex societies in the Fertile Crescent. This is now being challenged by a new argument based on evidence of early religion in Turkey.

I’ll have to think about using these questions in class. They seem particularly good for helping students consider the basic building blocks of human social life before diving into specific sociological phenomena.

Farming back on the upswing in Massachusetts

Posted on by

Farming is not a common occupation in the United States today. According to these figures from the EPA, less than 1% of Americans claim farming as an occupation and about 2% of people live on farms.

Yet the Boston Globe reports that farming is on the upswing in Massachusetts. According to the figures:

From 2002 to 2007, the number of farms in Massachusetts jumped by about 27 percent to 7,691, according to the US Department of Agriculture census. That’s a reversal from the previous five years, when there was a 20 percent drop in the number of farms and, presumably, farmers, many of whom sold land to developers.

But the start-up farms are smaller than the family enterprises of the past. The average farm in Massachusetts, 85 acres in 2002, was 67 acres five years later.

American society experienced such a shift away from agriculture from the late 1800s to today that I wonder if this is part of a shift toward a slightly more balanced world between agriculture and other sectors of society. There are plenty of books and pundits talking about how we are disconnected from the land and our food – perhaps a new generation is listening (and the article does make it sound like many of the new farmers are younger) and charting a new course.

(Even after an upswing, the number of farms in Massachusetts is still small. A lot more people would need to go into agriculture to become a movement.)
