Implicating suburban sprawl in the spread of ticks and pathogens

As new tick-borne illnesses spread, sprawl is part of the problem:

But as climate change, suburban sprawl, and increased international travel are putting more ticks and the pathogens they carry in the paths of humans, what’s becoming more urgently apparent is how the US’s tick monitoring systems are not keeping pace.

“It’s really a patchwork in terms of the effort that different areas are putting into surveillance,” says Becky Eisen, a tick biologist with CDC’s Division of Vector-Borne diseases. The federal public health agency maintains national maps of the ranges of different tick species, but they’re extrapolated from scattered data collected in large part by academic researchers. Only a few states, mostly in the Northeast, have dedicated tick surveillance and control programs. That leaves large parts of the country in a data blackout.

To help address that problem the CDC is funding an effort to identify the most urgent gaps in surveillance. It has also begun publishing guidance documents for public health departments on how to collect ticks and test them for diseases, to encourage more consistent data collection across different states and counties.

In an ideal world, says Eisen, every county in the US would send a few well-protected people out into fields and forests every spring and summer, setting traps or dragging a white flannel sheet between them to collect all the ticks making their homes in the grasses and underbrush. Their precise numbers, locations, and species would be recorded so that later on when they get ground up and tested, that DNA would paint a national picture of risk for exposure to every tick-borne pathogen in America. But she recognizes that would be incredibly labor-intensive, and with only so many public funding dollars to go around each year, there are always competing priorities.“But from a research perspective, that’s the kind of repeatable, consistent data we’d really want,” says Eisen. “That would be the dream.”

While there is little direct discussion of sprawl, I wonder if there are two problems at play.

First, sprawl puts more people in interaction with more natural settings. As metropolitan areas expand, more residents end up in higher densities in areas that previously had experienced limited human residence. More people at the wildland urban interface could potentially lead to more problems in both directions: humans can pick up diseases while nature can be negatively impacted by more people.

Second, increasing sprawl means more data needs to be collected as more people are at possible threat. Metropolitan areas (metropolitan statistical areas according to the Census Bureau) typically expand county by county as outer counties increase in population and have more ties to the rest of the region. Since many metropolitan regions expand in circles, adding more counties at the edges could significantly increase the number of counties that need monitoring. And as the article ends with, finding money to do all that data collection and analysis is difficult.

Making a horror film about illnesses carried by ticks would take some work to make interesting but these sorts of hidden and minimally problematic in terms of number of suburbanites at this point issues could cause a lot of anxiety.

Separating the ills of suburbia from the ills of the United States

The critiques of the American suburbs are common and persistent. But, how many of them are unique to the suburbs as opposed to multiple American settings or American society as a whole? A thought experiment with a number of the ills of suburbia:

  1. Consumerism. Present everywhere with displays of wealth such as expensive housing, cars, and technological goods alongside just having a lot of stuff. Certain suburban symbols may catch attention – such as McMansions and SUVs – but these are present all over the place. Excessive or wasteful consumption is not solely an American problem.
  2. Sprawl. This may seem like a uniquely suburban problem. Yet, numerous American cities have varying levels of density and lots of single-family home neighborhoods (even if these homes are closer together).
  3. Driving. Suburbs may be more dependent or designed around automobiles but so are most American cities and urban neighborhoods. And  rural areas would be very different without widespread access to cars.
  4. Conformity. Mass culture is everywhere, even if cities are often regarded as having more diversity and cultural experiences. This is related to consumerism as many Americans are thoroughly immersed (just see the figures on how much media Americans consume a day).
  5. Inequality. Across categories of race, class, and gender, American communities of all kinds experience problems. They may manifest differently in each context but addressing inequality in the suburbs would not solve the problem in the entire country.
  6. Lack of true community. Social ties seem to be more tenuous across the United States as a whole and the influence of and trust in institutions of all kinds has declined. Americans are famously individualistic, whether in suburbs or other settings.

Another way to think about it: did these problems begin in suburbs or are they amplified or exacerbated by suburbs? Imagine the United States where only 30% of American lived in suburbs: might driving and sprawl still be an issue? Would the problems of inequality be alleviated?

A test of taking Lyft from the train to the suburban office park exposes mass transit issues in the suburbs

One company in the Chicago suburbs is running a test to encourage employees to take the train to get close to their office and then use Lyft to complete the trip:

The two-year program aims to solve the “last mile” problem — how to bridge the gap between the train station or bus stop and the rider’s final destination. This problem is especially nettlesome for reverse commuters, who live in the city but work in the suburbs at jobs that are sometimes far from transit stops. More than 400,000 people commute every day from Chicago to jobs in the suburbs, according to the RTA…

GlenStar Properties is paying 75 percent of the cost of transporting employees at its Bannockburn complex on Waukegan Road to and from Metra stops in Deerfield, Highland Park, Highwood and Lake Forest. The Regional Transportation Authority is picking up the rest of the cost, up to $30,000 during the pilot…

The program, which launched in March and is the first of its type in Illinois, is starting small with just a few trips a day, according to the RTA. Bannockburn Lakes tenants get a monthly Lyft pass for the rides.

Many suburban companies, including Walgreens and Allstate, have some kind of shuttle bus program to get workers to and from Metra stations, said Michael Walczak, executive director of the Transportation Management Association of Lake-Cook, a nonprofit that works with companies and the private sector to figure out transit issues.

This is an interesting way to solve a common problem in both cities and suburbs: how to get people and goods that last step (or “last mile”) between a mass transit stop and their destination. Even in cities with good mass transit, the last step can cause a lot of problems.

This strikes me as the pragmatic solution to the larger problem of limited mass transit in the suburbs. The Chicago train system runs on the hub and spokes model where suburban communities, typically their downtowns, are connected to the Loop. This system may help funnel people into the center of Chicago but it is both difficult to get around the region and the train lines run into historic town centers, not necessarily the work and residential centers of today. Ride-sharing can help make up the difference by connecting train stops to workplaces. This can limit long-distance solo trips by car and allow more workers to not have a vehicle or to drive significantly less.

On the other hand, this solution could be viewed as less-than-ideal reaction to the real issue: sprawling suburban sites do not lend themselves to mass transit and the ride-sharing solution is just a band-aid to a much bigger issue. Chicago area suburbs have tried versions of this for decades including public bus systems in the suburbs to connect office parks to train stations, buses from remote parking lots to train stations, and private companies operating shuttle buses (as noted above). This all may work just for a limited number of workers who are located near rail lines and who are willing to use mass transit. But, most suburban workers – and they tend to work in other suburbs – have no chance of using timely and convenient mass transit to get to work. The densities just do not support this (and the office park in the story illustrates that this may be more feasible with denser concentrations of workers).

If companies, communities, and regional actors truly wanted to address these issues in the Chicago region, a more comprehensive plan is needed to nudge people closer together to both take advantage of existing mass transit and develop new options.

A call for the Green New Deal to address sprawl and where people live

Want to pass a Green New Deal to benefit the United States? One commentator suggests it must reckon with the legacy and persistence of sprawl:

The Green New Deal is ostensibly a jobs program, an environmental program, and a redistributive program. If it’s a jobs program, it must wrangle with spatial mismatch. If it’s an environmental program, it must tackle the fact that an all-electric fleet of cars is functionally, at this time, a pipe dream. And if it’s a redistributive program, it must grapple with how roads paved into suburban and exurban greenfield developments deepen, expand, and exacerbate segregation.

A Green New Deal must insist on a new, and better, land-use regime, countering decades of federal sprawl subsidy. The plan already recognizes the need to retrofit and upgrade buildings. Why not address their locations while we’re at it? Suggestions of specific policies that would enable a Green New Deal to address land use have already emerged: We could, simply, measure greenhouse gases from our transportation system or build more housing closer to jobs centers. Reallocating what we spend on building new roads to paying for public transit instead would go a long way toward limiting sprawl.

Where we live is no coincidence of preference. Federal policy has enforced inequities and disparities for both the environment and vulnerable people at a national scale. It’s never too late to address the most fundamental aspect of our carbon footprint: where we live. And building housing near jobs, transit, and other housing—rather than ultra-LEED-certified parking garages—is merely a political choice. No innovation required.

This makes sense: how much can the United States truly address environmental matters if it does not reckon for the actions of roughly the last century that encouraged decentralization?

Here is what I wonder: would it be harder to address sprawl or environmental issues? On one hand, climate change is contentious and partisan. On the other hand, going after sprawl would require taking on deeply ingrained American values. When Americans value single-family homes, driving, and all that the suburban life offers, shifting priorities and funds to denser housing, mass transit, and cities may prove difficult.

The environmental movement in the United States has roots in suburbia. Rachel Carson was inspired by her suburban settings to write Silent Spring. But, truly reforming land use as opposed to making suburbs greener is a tall task. Of course, important decisions made today could address the issue of subsidized sprawl. American suburbs are neither natural or have to last forever. It would likely take decades to see the consequences on the ground.

American land uses in a number of interesting maps

Bloomberg put together a set of graphics to illustrate how Americans use land. Here are a few of the maps interspersed with information. First, the general patterns of land use:

AmericanLandUseGeneral

The U.S. is becoming more urban—at an average rate of about 1 million additional acres a year. That’s the equivalent of adding new urban area the size of Los Angeles, Houston and Phoenix combined. U.S. urban areas have more than quadrupled since 1945…

AmericanLandUseComparative

More than one-third of U.S. land is used for pasture—by far the largest land-use type in the contiguous 48 states. And nearly 25 percent of that land is administered by the federal government, with most occurring in the West. That land is open to grazing for a fee.

There is some data here that could be viewed as conflicting: urban areas are the fastest growing land use – watch out for sprawl! – but the biggest land use overall is pasture and range – open land yet given over to creatures that are land and resource intensive!

One nice feature of these maps is that they are helpful for making comparisons between land uses. Given the size of the country plus the limited day-to-day experiences of many in different parts of the country, it can be hard to get a handle on all the land uses.

After looking this all over, I wonder what Americans and policymakers would say an ideal land use mix is for the entire country. This is a difficult question to answer, particularly since many people would not necessarily regularly encounter all the uses. If people want more protected land, what other land uses should be reduced and how would this affect individual lives as well as the American way of life?

 

McMansion owners as against preserving green space

A letter to the editor connects Mcmansion owners with an unwillingness to look toward the public good:

It seems that more often than not folks who live in huge McMansions on private estates, drawing big government pensions and other income streams, are the ones making the biggest noise about keeping things the same in the county (Letter to the Editor, “Snapshot of Rappahannock’s Future,” Demaris Miller, July 19).

Of course they would! They don’t need to worry about finding decent paying jobs or affordable housing without having to move out of the county as so many people here do. They’ve got plenty of fine space to take walks and entertain their grandkids.

The county has many choices for where to go — we could allow factories and warehouses, or suburban sprawl, or tourism with a NASCAR track, an amusement park, skate boarding and all. Or we could stick to a plan for growth that preserves our scenic rural character while encouraging people to visit and share that beauty and spend a little money here. A safe bike and walking path with gorgeous views of the Blue Ridge certainly fits in that category.

The McMansions cited here must have larger properties where owners can enjoy the outdoors. This would contrast with one possible trait of McMansions where they are the result of teardowns.

On the other hand, McMansions are linked here to sprawl. This is a common argument as McMansions are often part of an expanding suburbia where homes, roads, and development gobbles up open land, green space, and public space. Additionally, these are wealthy sprawling suburbanites who can take care of their own financial interests.

More broadly, this letter gets at broader issues involving McMansions and suburbs: just how much growth is desirable? How does a community weigh the construction of housing versus protecting natural space that residents and visitors can enjoy? Growth is generally good in suburban areas and even if certain spaces are protected, the general tenor of development can overwhelmingly change the character of a place from a more rural or open area to a denser one.

 

Fight McMansions to slow down the sixth mass extinction

A letter to the editor in the Eugene Weekly links McMansions and broad environmental concerns:

We’re living through the sixth mass extinction. We see this firsthand in Lane County. Oak savannah is the most endangered habitat in the United States…

In this context, a group of neighbors and I are fighting a multi-million dollar “McMansion” development project in our area. “The Vineyards at Gimpl Hill” describes itself as a selection of “gracious estates” for “secure, sophisticated country living … the premier development in Lane County for discerning people.”

This project will destroy or impact 80 acres of prime wildlife habitat home to deer, elk, bears, cougars, wild turkeys, bobcats and a wide variety of other species.

Destroying large areas of habitat and impacting the area with higher traffic and additional access roads is a course of action I cannot support. These ostentatious houses will cost millions, and the developer (Roy Carver) stands to make millions more.

On one hand, 80 acres of land is a drop in the bucket of land in urban areas in the United States. On the other hand, this argument involving McMansions is a common one: McMansions represent the senseless sprawl that is gobbling up land, threatening wildlife, and contributing to our destruction of the environment.

I also suspect that because these homes are larger and more expensive (as well as more profitable, as this letter notes), they tend to get more attention in the same way that McDonald’s and Walmart receive attention for their environmental impact in their own sectors (fast food restaurants and retail stores, respectively). Sprawl over the past century or so in the United States involves a broad range of homes and other buildings, not just the big homes for the wealthy.

It also helps in this case to have a pejorative term for these large homes. They are not just “luxury homes” or places where wealthier people live; they are mass-produced, inferior quality homes that do not deserve the space they are taking up.

Finally, I wonder what the more compelling environmental appeal is to other locals: is it better to refer to (1) massive-scale change like the sixth mass extinction, (2) the loss of local nature (land and animals), or (3) the unnecessary use of land and resources for these larger homes? I suspect each of these could appeal to different people.
