August 2018 in Review

Most frightening stories:

  • In certain provinces with insurgent activity, the Chinese government is reportedly combining surveillance and social media technologies to score people and send those with low scores to re-education camps, from which it is unclear if anyone returns.
  • Noam Chomsky doesn’t love Trump, but points out that climate change and/or nuclear weapons are still existential threats and that more mainstream leaders and media outlets have failed just as miserably to address them as Trump has. In related news, the climate may be headed for a catastrophic tipping point and while attention is mostly elsewhere, a fundamentalist takeover of Pakistan’s nuclear arsenal is still one of the more serious risks out there.
  • The U.S. government is apparently very worried about a severe cyber attack. Also, a talented 11-year-old can hack a voting machine.

Eco-cities in Japan and China

Here’s a paper comparing and contrasting two eco-city developments in Japan and China.

Ecological urbanism in East Asia: A comparative assessment of two eco-cities in Japan and China

The growth of projects translating the concept of eco-city into practices has accelerated during the last fifteen years, making the eco-city a global phenomenon. Asia in particular has witnessed notable developments, characterized by strong governmental intervention and national initiatives to create model eco-cities. In Japan, the central government launched an “Eco-Model Cities” program in 2008 and has designated twenty-three model cities. In China, hundreds of municipalities have pursued plans to become an eco- or low-carbon city following the government’s demonstration projects. Across East Asia, the eco-city is promoted as an innovative urban policy capable of advancing the agendas of sustainable urbanization and the realignment of the post-industrial urban economy.

This paper compares the policies and strategies of developing eco-cities in Japan and China using Kitakyushu and Tianjin Eco-city as case studies. It examines these cities’ common and contrasting approaches to ecological urbanism, their respective technological and urban design strategies, the relationship between eco-city building and local economic development, and the roles played by different stakeholders in this effort. The research focuses on their Key Performance Indicator systems and the spatial qualities they anticipate, which reflect fundamentally different ideas about what societal role an eco-city should best play. The comparative method sheds light on debates around important aspects of planning and managing an eco-city––namely, between new town and retrofit development, between top-down directive and bottom-up force, and between the eco-city as technology and as culture. This paper thus offers critical insight into the changing notions of urbanity within Asian society.

Most hopeful stories:

  • One large sprawling city could be roughly the economic equivalent of several small high-density cities. This could potentially be good news for the planet if you choose in favor of the latter, and preserve the spaces in between as some combination of natural land and farm land.
  • The problems with free parking, and solutions to the problems, are well known. This could potentially be good news if anything were to be actually done about it. Self-parking cars could be really fantastic for cities.
  • The coal industry continues to collapse, and even the other fossil fuels are saying they are a bunch of whining losers. And yes, I consider this positive. I hope there aren’t too many old ladies whose pensions depend on coal at this point.

what’s going on with parking in Australia

This article summarizes the problems with free parking pretty well. Then it goes on to lament that Australian cities aren’t moving faster to implement the policies that planners and engineers know (or should know) would work.

The third major approach is characterised as responsive. This approach is based around pricing parking to account more accurately for actual demand, to incentivise use of active and sustainable modes of transport, and advocating generally for more efficient publicly-shared spaces (not exclusively used by cars) and area-based planning. It can be said to include Donald Shoup’s well-known reforms, as well as Paul Barter’s adaptive and walkable parking reforms…

Parking can directly compromise the adoption of active and sustainable modes of transport. Firstly, free and easily accessible parking contributes to induced driving and car ownership. For example, researchers from Oslo’s Institute of Transport Economics found that access to private household parking facilities triples the likelihood of car ownership, whereas increasing the distance between parking and destinations reduces car mode share. This means planners must disincentivize convenience (including factors of distance, time and pricing), and reduce its domination of urban space. Secondly, on-street parking can directly compete for limited road space, inhibiting the ability to reallocate street space to improved pedestrian or cycling infrastructure (such as bicycle lanes), or to create priority lanes for road-based public transport (such as buses or trams). Additionally, on-street parking spurs congestion from “cruising” for parking spaces, and movements in and out of spaces, and well as increasing the risk of “dooring” cyclists.

 

one large or many smaller cities for maximum productivity

This paper looks at data from 306 cities in China to identify trends in how different sizes and densities of cities relative to each other affect economic productivity. The interesting finding is that it is best to have either one big low-density city or many smaller high-density ones.

How did urban polycentricity and dispersion affect economic productivity? A case study of 306 Chinese cities

This article aims to assess the impacts of urban spatial structure on economic productivity. Drawing upon detailed gridded population data of 306 Chinese cities at the prefecture level and above, we identify their urban (sub)centers through exploratory spatial data analysis, construct indicators to measure their degrees of polycentricity and dispersion, and model the impacts of spatial structure on urban productivity. A regression analysis reveals that economic productivity is significantly associated with urban spatial structure. Conditioning on other factors, higher degrees of dispersion are associated with lower level of urban productivity whereas the effects of polycentricity depend on urban population density. Less densely populated cities are likely to have higher productivity levels when they are more monocentric, while urban productivity of cities with high population density tend to benefit from a more polycentric structure. The paper concludes with spatial planning implications.

January 2018 in Review

Most frightening stories:

  • Larry Summers says we have a better than even chance of recession in the next three years. Sounds bad, but I wonder what that stat would look like for any randomly chosen three year period in modern history.
  • The United States is involved in at least seven wars: Afghanistan, Iraq, Syria, Yemen, Libya, Somalia, and Pakistan. Nuclear deterrence may not actually the work.
  • Cape Town, South Africa is in imminent danger of running out of water. Longer term, there are serious concerns about snowpack-dependent water supplies serving large urban populations in Asia and western North America.

more on movement ecology

I’m still digging into movement ecology, which has always fascinated me. Here is a comprehensive recent literature review on the subject.

Trends and missing parts in the study of movement ecology

Movement is important to all organisms, and accordingly it is addressed in a huge number of papers in the literature. Of nearly 26,000 papers referring to movement, an estimated 34% focused on movement by measuring it or testing hypotheses about it. This enormous amount of information is difficult to review and highlights the need to assess the collective completeness of movement studies and identify gaps. We surveyed 1,000 randomly selected papers from 496 journals and compared the facets of movement studied with a suggested framework for movement ecology, consisting of internal state (motivation, physiology), motion and navigation capacities, and external factors (both the physical environment and living organisms), and links among these components. Most studies simply measured and described the movement of organisms without reference to ecological or internal factors, and the most frequently studied part of the framework was the link between external factors and motion capacity. Few studies looked at the effects on movement of navigation capacity, or internal state, and those were mainly from vertebrates. For invertebrates and plants most studies were at the population level, whereas more vertebrate studies were conducted at the individual level. Consideration of only population-level averages promulgates neglect of between-individual variation in movement, potentially hindering the study of factors controlling movement. Terminology was found to be inconsistent among taxa and subdisciplines. The gaps identified in coverage of movement studies highlight research areas that should be addressed to fully understand the ecology of movement.

An idea that has always fascinated me is the idea that when designing a development or an even an entire urban area, you could actually lead with ecology, then layer hydrology, infrastructure, housing, and the other human elements on top of that. Sadly, I don’t think I know a single engineer or urban planner who would be particularly open minded to this idea.

cities and gamification

This article is about applying gamification to the planning and running of cities.

Cities and the politics of gamification

Gamification is widely intended as the mobilisation and implementation of game elements in extra-ludic situations, including the management of social problems and issues. By mobilising virtual rewards and playful elements, mobile apps, websites, social initiatives and even urban policies are getting more and more gamified. The aim of this viewpoint paper is to stimulate a critical discussion on the potential relationships between gamification processes and cities, particularly by reflecting on the cultures of gamification and by discussing potential lines of research for urban studies.

November 2017 in Review

Most frightening stories:

  • I thought about war and peace in November. Well, mostly war. War is frightening. The United States of America appears to be flailing about militarily all over the world guided by no foreign policy. Big wars of the past have sometimes been started by overconfident leaders thinking they could get a quick military victory, only to find themselves bogged down in something much larger and more intractable than they imagined. But enemies are good to have – the Nazis understood that a scared population will believe what you tell them.
  • We should probably be sounding the alarm just as urgently, if not more urgently, on biodiversity as we are on global warming. But while the case against global warming is so simple most children can grasp it, the case against biodiversity loss is more difficult to articulate.
  • A theory of mass extinctions of the past is that they have been caused by massive volcanic eruptions burning off underground fossil fuels on a massive scale. Only, not quite at the rate we are doing it now. Rapid collapse of ice cliffs is another thing that might get us.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

  • You can get an actuarial estimate of your life span online. You can also search your local library catalog automatically whenever you consider buying a book online. Libraries in small, medium, and large towns all over the U.S. appear to be included.
  • “Transportation as a service” may cause the collapse of the oil industry. Along similar but more mainstream lines, NACTO has released a “Blueprint for Autonomous Urbanism“, which is my most popular post at the moment I am writing this.
  • It’s possible that the kind of ideal planned economy envisioned by early Soviet economists (which never came to pass) could be realized with the computing power and algorithms just beginning to be available now.

 

the most rat-infested cities

Orkin has released a list of which cities it has trapped the most rats in. Interesting, except they don’t appear to have controlled for population or area. So, the biggest cities have the most rats, which doesn’t tell us much except that rats are present in cities. It would be more interesting to know how many rats are present per square mile or per 1,000 people per square mile. Which I suppose you could try to figure out from this data.
