“new vision” for suburbia

This article from The Smithsonian presents some ideas on the future of suburbia.

With truly autonomous vehicles still years away, no one can say with much certainty if they will result in people spending less time in cars. But Berger does foresee one big potential benefit—much less pavement. Based on the notion that there likely will be more car-sharing and less need for multiple lanes since vehicles could continuously loop on a single track, Berger believes the amount of pavement in a suburb of the future could be cut in half. You would no longer need huge shopping center parking lots, or even driveways and garages.

Not only would fewer paved surfaces increase the amount of space that could be used for carbon-storing trees and plants, but it also would allow more water to be absorbed and reduce the risk of flooding in cities downstream.

That kind of interdependence between suburbs and downtowns is at the heart of how Berger and others at the CAU see the future. Instead of bedroom communities of cul-de-sacs and shopping malls, the suburbs they’ve imagined would focus on using more of their space to sustain themselves and nearby urban centers—whether it’s by providing energy through solar panel micro-grids or using more of the land to grow food and store water.

I almost liked the article until I got to the Joel Kotkin quote:

“The reality is that the large majority of people want to live in suburbs,” says Joel Kotkin, a fellow of urban studies at Chapman University in California and the author of The Human City: Urbanism for the Rest of Us. “People make these choices for all kinds of reasons that urban theorists don’t pay attention to. They’d rather live in a detached house than in an apartment building. Or they can’t afford to live in the middle of a city. Or they’re worried about where their kids will go to school.”

It’s a scare tactic. Yes, dictators of the past may have forced people into high rise housing blocks at gunpoint in a few cases. That is not happening in the United States right now. In fact, most of us are not able to make a choice between car-dependent and walkable communities because walkable communities are in short supply. Things that are in short supply and high demand tend to be expensive. They are expensive because they are desirable and limited, not because they are undesirable and people are being forced to live there against their will. The nascent trend toward city living would have to continue for a long, long time before there is any lack of suburbs to choose from.

I can’t deny that the state of many urban school districts is problematic. Schools in the United States tend to be locally funded, so that areas with higher concentrations of poverty have worse schools. And areas with higher concentrations of minorities have worse schools because racist and ideologically anti-city politicians from rural areas are able to starve them of funding in many states. All this leads to a downward spiral of poor outcomes and low expectations that is hard to break out of.

Pennsylvania governor on anti-city policies

Here is the Pennsylvania governor talking about how state policy disadvantages cities and what could be done about it.

  • Regional land use planning
  • Zoning ordinances and planning codes that allow mixed use, high density communities
  • Urban growth boundaries like Portland, Oregon
  • Inclusive zoning like Montgomery County, Maryland
  • Change public infrastructure investment strategy to promote redevelopment of old settlements
  • Strike a better balance between highway and mass transit funding
  • Consolidate and restore old industrial sites for redevelopment
  • Reform local tax policies starting with the state taking a bigger share of funding for public education

In the end, the struggle for our cities will depend on the outcome of the competition between suburbs and cities. The outcome will largely be determined by the extent to which that competition is a fair one.

I like most of this, but I’m not so sure about the city vs. suburb talk. Part of regional coordination and planning would be to think of the success of a metro area as a whole, from its most intensely urbanized core out to the less dense areas. But I like the urban growth boundary concept, because it puts a lower limit on how far out that development can go and how much infrastructure it can gobble up to get services to people who are spread out, at every else’s expense. Education funding could be done well at this metro area scale, rather than pitting many tiny municipalities and school districts against each other as it does now (a problem across the U.S., but Pennsylvania is particularly bad). I am skeptical of the state, which draws much of its political power from the empty spaces between metro areas, being the solution. Its existence depends on sucking resources out of the population centers where economic activity happens and taxes get paid, and redistributing them to the empty spaces. Even more insidious, in our state at least racism plays a role in the urban vs. rural divide, as well as the city center vs. suburban divide.

Jane Jacobs

This article about Jane Jacobs is most useful because it mentions all of her major works. It talks quite a bit about Dark Age Ahead. I read Dark Age Ahead, and yet it doesn’t stick in my mind. I am ashamed to admit that I have only read the first chapter of The Death and Life of Great American Cities, and yet that first chapter sticks in my mind. I am lucky enough to live in one of the great American cities, and in fact a neighborhood that she visited and commented on. I had to spend a few years away from it to really come to understand how great a walkable street grid with a mix of homes, businesses, workplaces and green spaces really is, and how rare it unfortunately is. One day I’ll sit down on a bench in one of those green spaces and finish Death and Life.

autonomous vehicles displacing traditional vehicles

If self-driving cars come into their own, will they reduce the total amount of vehicles on the road, or will everybody who owns a car now just buy a self-driving one? This study set in Austin says that each self-driving car will displace 9 normal cars. So even if the same or more cars are in motion at any given time, there will be a lot less land required for parking. That land can be used for something else – housing, commerce, habitat, recreation, gardening/farming, or some combination. Bring it on!

Remaking Economic Development

This is a new Brookings study on a vision for economic development at the metro scale. Here’s an excerpt, but the rest is worth reading.

As Michael Porter, the Harvard authority on competitiveness, describes it, the anchor firms, supply chains, supporting entities and organizations, research centers and specialized knowledge assets that make up industry clusters arise from a “highly localized process” that creates differentiated competitive advantages tailored for particular industry clusters.

Those assets are sometimes called “market drivers,” “factors of production,” or the “industrial commons”— because they benefit a wide array of firms. They include applied research and technical expertise, supports for entrepreneurial activity, robust pipelines of skilled labor, deep benches of suppliers and related firms, globally connected infrastructure, and responsive, predictable governance to maintain them all. It is the productive mix and synergy among these distinctive drivers—innovation, traded sectors, human capital, infrastructure, and governance—that create the conditions in which industries thrive, create value, and generate growth and income.

Globalization and technology have not dispersed these market assets but instead have further concentrated them in cities and metropolitan regions, with leading centers of knowledge and production capturing an increasingly greater share of specific market opportunities.

That is in part because innovation today reinforces the power of place. The rapid pace of competition requires solutions often developed through collaborations among firms, research institutions, national labs, competitors, customers, venture capitalists, and entrepreneurs—collaborations that are most readily forged through the networks formed within metropolitan regions.

 

This sounds right to me. Policies like minimum wage and affordable housing have their place, but ultimately I feel like they are treating the symptom and not the disease. The pie has to be growing.

City Observer’s Weekly Roundup

City Observer has a nice weekly roundup with way more stuff than I could actually hope to read in a week. This example covers everything from car “demonization” to affordable housing to real estate capital gains.

I’ve been in the process of trying to form opinions on these issues for many years. On cars, I think they are demons. At least, private cars and all the waste and environmental and social hell they have unleased on the entire world. We should design cities and connections between them so we almost never need them. Then we can keep a few share cars and taxis around. On affordable housing, I don’t have the answers that have alluded everyone else forever, but in general I like focusing on the idea of supporting well-functioning markets that are able to set appropriate prices. When you distort prices with large subsidization schemes in a world of finite resources, you end up with distorted systems and unintended consequences. Better to find ways to remove hidden distortions, subsidies, and discrimination, constrain supply less, help people get around efficiently, and generally help them make an income and build assets so they can afford what housing costs. In the U.S., all the tax deductions and exceptions for homeowners and subsidization of inefficient low-density infrastructure are forms of distortion that maybe should be phased out. But please don’t take away my personal subsidies all at once, because I was counting on them when I made my last round of housing and financial decisions.

dots moving around on a map

This is just dots moving around on a map, but I find these dots very engaging in helping me understand urban planning concepts and results of a simulation.

I found this on R bloggers, which talks about how the simulation and map were created.

Data Scientist Todd Schneider has followed-up on his tour-de-force analysis of Taxi Rides in NYC with a similar analysis of the Citi Bike data. Check out the wonderful animation of bike rides on September 16 below. While the Citi Bike data doesn’t include actual trajectories (just the pick-up and drop-off locations), Todd has “interpolated” these points using Google Maps biking directions. Though these may not match actual routes (and gives extra weight to roads with bike lanes), it’s nonetheless an elegant visualization of bike commuter patterns in the city.

January 2016 in Review

I’m going to try picking the three most frightening posts, three most hopeful posts, and three most interesting posts (that are not particularly frightening or hopeful) from January.

3 most frightening posts

  • Paul Ehrlich is still worried about population. 82% of scientists agree.
  • Thomas Picketty (paraphrased by J. Bradford Delong) says inequality and slow growth are the norm for a capitalist society. Joseph Stiglitz has some politically difficult solutions: “Far-reaching redistribution of income would help, as would deep reform of our financial system – not just to prevent it from imposing harm on the rest of us, but also to get banks and other financial institutions to do what they are supposed to do: match long-term savings to long-term investment needs.”
  • Meanwhile, government for and by big business means the “Deep State” is really in control of the U.S. In our big cities, the enormous and enormously dysfunctional police-court-prison system holds sway over the poor.

3 most hopeful posts

3 most interesting posts

  • There are some arguments in favor of genetically modified food – they have increased yields of some grains, and there is promise they could increase fish yields. 88% of scientists responding to a Pew survey said they think genetically modified food is safe, but only 37% of the U.S. public thinks so. In other biotech news, Obama’s State of the Union announced a new initiative to try to cure cancer. In other food news, red meat is out.
  • Not only is cash becoming obsolete, any physical form of payment at all may become obsolete.
  • The World Economic Forum focused on technology: “The possibilities of billions of people connected by mobile devices, with unprecedented processing power, storage capacity, and access to knowledge, are unlimited. And these possibilities will be multiplied by emerging technology breakthroughs in fields such as artificial intelligence, robotics, the Internet of Things, autonomous vehicles, 3-D printing, nanotechnology, biotechnology, materials science, energy storage, and quantum computing.”

 

fixing sidewalks at point of sale

You can require homeowners (actually home sellers) to fix sidewalks when they sell their property (“point of sale”). Los Angeles does this, which Donald Shoup says is a great idea. Philadelphia has a similar legal framework where the homeowner technically owns and is responsible for the sidewalk, but does not require point of sale repairs. The city can write you a ticket for a broken sidewalk if they want to, just like any other code violation, but that is not too often done because the public outcry would be pretty severe. Also, it’s the transportation agency that is supposed to do this and not the code enforcement agency, so may not fit clearly within their mission and priorities. One more interesting thing the article mentions is that if sidewalks were made more clearly a code violation, this would show up in real estate records, and there would then be some pressure from mortgage and insurance companies to fix them.

Another option, of course, would be for the city to take over the sidewalk, along with street trees and infrastructure up to the house line. This could be part of a grand vision for how to implement 21st century urban infrastructure – complete streets, better materials than tired old concrete and asphalt, urban forests, public spaces, modernized water, sewer, gas, electric, and communications infrastructure. I for one would be indifferent to paying slightly higher taxes rather than being ticketed for code violations for I have very little control over, and this would also be more equitable. But it’s easier for the politicians to pin in on the private owner and say it has “zero cost”.

2015 Year in Review

I’m going to try picking the most frightening, most hopeful, and most interesting post from each month. If the most interesting is also the most frightening or most hopeful, I’ll pick the next most interesting. Then I’ll have 12 nominees in each category and I’ll try to pick the most frightening, hopeful, and interesting posts of the year.

JANUARY

Most frightening: Johan Rockstrom and company have updated their 2009 planetary boundaries work. The news is not getting any better. 4 of the 9 boundaries are not in the “safe operating space”: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen).

Most hopeful: It is starting to seem politically possible for the U.S. to strengthen regulation of risk-taking by huge financial firms.

Most interesting: Taxi medallions have been called the “best investment in America”, but now ride-sharing services may destroy them.

FEBRUARY

Most frightening: There are some depressing new books out there about all the bad things that could happen to the world, from nuclear terrorism to pandemics. Also a “financial black hole”, a “major breakdown of the Internet”, “the underpopulation bomb”, the “death of death”, and more!

Most hopeful: A new study suggests a sudden, catastrophic climate tipping point may not be too likely.

Most interesting: Government fragmentation explains at least part of suburban sprawl and urban decline in U.S. states, with Pennsylvania among the worst.

MARCH

Most frightening: The drought in California and the U.S. Southwest is the worst ever, including one that wiped out an earlier civilization in the same spot. At least it is being taken seriously and some policies are being put in place. Meanwhile Sao Paulo, Brazil is emerging as a cautionary tale of what happens when the political and professional leadership in a major urban area fail to take drought seriously. Some people are predicting that water shortages could spark serious social unrest in developing countries.

Most hopeful: If we want to design ecosystems or just do some wildlife-friendly gardening, there is plenty of information on plants, butterflies, and pollinators out there. There is also an emerging literature on spatial habitat fragmentation and how it can be purposely designed and controlled for maximum benefit.

Most interesting (I just couldn’t choose between these):

  • Innovation in synthetic drugs is quickly outpacing the ability of regulatory agencies to adapt. (I struggled whether to put this in the negative or positive column. Drugs certainly cause suffering and social problems. But that is true of legal tobacco and alcohol, and prescription drugs, as well as illegal drugs. The policy frameworks countries have used to deal with illegal drugs in the past half century or so, most conspicuously the U.S. “war” on drugs, have led to more harm than good, and it is a good thing that governments are starting to acknowledge this and consider new policies for the changing times.)
  • Germ-line engineering is much further along than anyone imagined.” This means basically editing the DNA of egg and sperm cells at will. I put this in the positive column because it can mean huge health advances. Obviously there are risks and ethical concerns too.

APRIL

Most frightening: A group of well-known economists is concerned that the entire world has entered a period of persistently low economic growth, or “secular stagnation“.

Most hopeful: Donald Shoup, author of The High Cost of Free Parking, is retiring. That might sound bad, but his ground-breaking ideas are continuing on and actually seem to be going mainstream.

Most interesting:

  • Biotechnology may soon bring us the tools to seriously monkey with photosynthesis. (This is one of those stories where I struggle between the positive and negative columns, but clearly there is a potential upside when we will have so many mouths to feed.)
  • Peter Thiel thinks we can live forever. (positive, but do see my earlier comment about mouths to feed…)

MAY

Most frightening: We’ve hit 400 ppm carbon dioxide in the atmosphere, not just some places sometimes but pretty much everywhere, all the time.

Most hopeful: The rhetoric on renewable energy is really changing as it starts to seriously challenge fossil fuels on economic grounds. Following the Fukushima disaster, when all Japan’s nuclear reactors were shut down, the gap was made up largely with liquid natural gas and with almost no disruption of consumer service. But renewables also grew explosively. Some are suggesting Saudi Arabia is supporting lower oil prices in part to stay competitive with renewables. Wind and solar capacity are growing quickly in many parts of the world.Lester Brown says the tide has turned and renewables are now unstoppable.

Most interesting: Human chemical use to combat diseases, bugs, and weeds is causing the diseases, bugs and weeds to evolve fast.

JUNE

Most frightening: One estimate says that climate change may reduce global economic growth by 3% in 2050 and 7-8% by 2100. Climate change may also double the frequency of El Nino. The DICE model is available to look at climate-economy linkages. Dennis Meadows and Jorgen Randers describe what a coming long, slow decline might look like. Rising temperatures in the Arctic are drying things out, leading to more fires, which burns more carbon, which raises temperatures, in an accelerating feedback loop.

Most hopeful: Stock values of U.S. coal companies have collapsed.

Most interesting: According to Paul Romer, academic economics has lost its way and is bogged down in “mathiness”.

JULY

Most frightening: James Hansen is warning of much faster and greater sea level rise than current mainstream expectations.

Most hopeful: Edible Forest Gardens is a great two book set that lays out an agenda for productive and low-input ecological garden design in eastern North America. You can turn your lawn into a food forest today.

Most interesting:

AUGUST

Most frightening: Steven Hawking is worried about an artificial intelligence arms race starting “within years, not decades”.

Most hopeful: It may be possible to capture atmospheric carbon and turn it into high-strength, valuable carbon fiber. This sounds like a potential game-changer to me, because if carbon fiber were cheap it could be substituted for a lot of heavy, toxic and energy-intensive materials we use now, and open up possibilities for entirely new types of structures and vehicles.

Most interesting:

  • gene drive” technology helps make sure that genetically engineered traits are passed along to offspring.
  • Technology marches on – quantum computing is in early emergence, the “internet of things” is arriving at the “peak of inflated expectations”, big data is crashing into the “trough of disillusionment”, virtual reality is beginning its assent to the “plateau of productivity”, and speech recognition is arriving on the plateau. And super-intelligent rodents may be on the way.
  • Robotics may be on the verge of a Cambrian explosion, which will almost certainly be bad for some types of jobs, but will also bring us things like cars that avoid pedestrians and computer chips powered by sweat. I for one am excited to be alive at this moment in history.

SEPTEMBER

Most frightening: Climate may be playing a role in the current refugee crisis, and the future may hold much more of this.

Most hopeful: The right mix of variety and repetition might be the key to learning.

Most interesting: Edward Tufte does not like Infographics.

OCTOBER

Most frightening: Corrupt Russian officials appear to be selling nuclear materials in Moldova.

Most hopeful: Elephants seem to have very low rates of cancer. Maybe we could learn their secrets.

Most interesting: Stephen Hawking is worried about inequality and technological unemployment.

NOVEMBER

Most frightening: I noticed that Robert Costanza in 2014 issued an update to his seminal 1997 paper on ecosystem services. He now estimates their value at $125 trillion per year, compared to a world economy of $77 trillion per year. Each year we are using up about $4-20 trillion in value more than the Earth is able to replenish. The correct conclusion here is that we can’t live without ecosystem services any time soon with our current level of knowledge and wealth, and yet we are depleting the natural capital that produces them. We were all lucky enough to inherit an enormous trust fund of natural capital at birth, and we are spending it down like the spoiled trust fund babies we are. We are living it up, and we measure our wealth based on that lifestyle, but we don’t have a bank statement so we don’t actually know when that nest egg is going to run out.

Most hopeful: There are plenty of ways to store intermittent solar and wind power so they can provide a constant, reliable electricity source.

Most interesting: Asimov’s yeast vats are finally here. This is good because it allows us to produce food without photosynthesis, but bad because it allows us to produce food without photosynthesis.

DECEMBER

Most frightening: Cyberattacks or superflares could destroy the U.S. electric grid.

Most hopeful: We had the Paris agreement. It is possible to be cynical about this agreement but it is the best agreement we have had so far.

Most interesting: I mused about whether it is really possible the U.S. could go down a fascist path. I reviewed Robert Paxton’s five stages of fascism. I am a little worried, but some knowledgeable people say not to worry. After reading Alice Goffman’s book On the Runthough, one could conclude that a certain segment of our population is living in a fascist police state right now. There is some fairly strong evidence that financial crises have tended to favor the rise of the right wing in Europe.

DISCUSSION

Well, one thing that certainly jumps out on the technology front is biotechnology. We have a couple articles about the possibility of drastic increases in the human lifespan, and what that would mean. “Germ-line engineering”, “gene drive”, and “CRISPR” are all ways of monkeying with DNA directly, even in ways that get passed along to offspring. To produce more food, we may be able to monkey with the fundamentals of photosynthesis, and if that doesn’t work we can use genetically engineered yeast to bypass photosythesis entirely.

At the risk of copyright infringement, I am reproducing the “Gartner hype cycle” below, which was mentioned in one of the posts from August.

Gartner Hype Cycle

Gartner Hype Cycle

Government and corporate labs have been making huge advances in biotechnology in the last decade or so, so it is well beyond the “innovation trigger”. It has not yet reached the “peak of inflated expectations” where it would explode onto the commercial and media scene with a lot of fanfare. I expect that will happen. We will probably see a biotech boom, a biotech bubble, and a biotech bust similar to what we saw with the computers and the internet. And then it will quietly pervade every aspect of our daily lives similar to computers and the internet, and our children will shrug and assume it has always been that way.

Obviously there are dangers. A generation of people that refuse to die on time would be one. Bioterrorism is obviously one. Then there is the more subtle matter that as we raise the limit on the size our population and consumption level can attain, the footprint of our civilization will just grow to meet the new limit. When and how we come up against these limits, and what to do about it, is the subject of the updates to two seminal papers on these issues, by Rockstrom and Costanza. We have entered an “unsafe operating space” (Rockstrom), where we are depleting much more natural capital each year than the planet can replenish (Costanza), and there will be consequences. The Paris agreement is one hopeful sign that our civilization might be able to deal with these problems, but even if we deal with the carbon emission problem, it might be too late to prevent the worst consequences, and there are going to be “layers of limits” as the authors of Limits to Growth put it all those decades ago. If we take care of the global warming problem and figure out a way to grow food for 50 billion people, eventually we will grow to 50 billion people and have to think of something else.

So without further ado:

Most frightening: I can’t pick just one. In the relatively near term, it’s the stalling out of the world economy; the convergence of climate change, drought, and the challenge of feeding so many people; and the ongoing risks from nuclear and biological weapons.

Most hopeful: I see some hope on energy and land use issues. The Paris agreement, combined with renewable energy and energy storage breakthroughs, the potential for much more efficient use of space in cities rather than letting cars take up most of the space, are all hopeful. The possibility of making carbon fiber out of carbon emissions is a particularly intriguing one. At my personal scale, I am excited to do some sustainable gardening of native species that can feed both people and wildlife. I don’t expect my tiny garden to make a major difference in the world, but if we all had sustainable gardens, they were all connected, and we weren’t wasting so much space on roads and parking, it could start adding up to a much more sustainable land use pattern.

Most interesting: I’ve already mentioned a lot of stuff, so I will just pick something I haven’t already mentioned in the discussion above: the rise of synthetic drugs. It’s just an interesting article and makes you think about what it will mean to have advanced chemical, information, and biological technologies in the hands of the little guy, actually many, many little guys. It is a brave, new, dangerous, exciting world indeed. Happy new year!
