"A host of environmental factors are threatening to push a crowded capital toward a breaking point."
Seth Dixon's insight:
Urban ecology, environmental justice, gendered inequities, primate city politics, the struggle of growing megacities…it’s all here in this fantastic piece of investigative reporting. The article highlights the ecological problems that Mexico City faces (high-altitude exacerbates air pollution, interior drainage worsens water pollution, limited aquifers that are overworked lead to subsidence, importing water outside of the basin requires enormous amounts of energy, etc.). just because the article doesn't use the word 'geography' doesn't mean that it isn't incredibly geographic. All of these problems are at the heart of human-environmental nexus of 21st century urbanization.

Anne Hidalgo says she wants to cut the number of cars in French capital by half as part of campaign to tackle pollution
Seth Dixon's insight:
The world's biggest cities are struggling to maintain access to congested downtown areas and still ensure that the downtown maintains it's historic sense of place that generate so much tourism and concentration of cultural amenities. Pollution is driving cities to change as the private automobile as the default mode of transportation becomes less feasible and unsustainable as cities expand to be far larger than they ever have been before.

"Asia's rapid urbanisation is changing the very shape and nature of what we think of as a city. It's not just the rapid increase in their numbers or their sheer size that makes these megacities fascinating. They look, feel and behave differently, too."
Seth Dixon's insight:
The term megacity (a city with a population greater than 10 million) has been around for a while and there wasn't much linguistic need to describe something bigger. Today, most megacities are more like Lagos and Mumbai, places of extreme wealth asymmetries than the global cities of New York City and London. Some are now using the term metacity to describe cities with populations of 20 million. Asian metacities are a good place to start thinking about the largest urban regions that are increasingly dominating economic, political and cultural affairs.

In 1950, there were only two megacities, London and New York, with populations of more than 10m. In 2010, Tokyo was top of the list of the world’s largest cities, New York was only just scraping into the top 10, and London had dropped off the bottom. New York will join it in megacity oblivion in less than a decade and, with the exception of Tokyo, every other megacity will be in what is referred to as the 'global south'. To earn a place in the top 10, cities will soon need to boast a population of 20m or more. This is a new breed of city – the metacity."

The amount of rainfall a place gets isn't the only factor in how much water is available to it. These major urban areas show how dire the coming global freshwater shortage could get.
Seth Dixon's insight:
Seen from space, this planet is a blue marble, a world where the surface is dominated by water. The Pacific Ocean alone is nearly half of the surface area of our planet. Add in polar ice caps and the rivers and lakes, we can see that water profoundly impacts Earth. Yet most of that water is salt water (97%) and two-thirds of our non-salty water locked away in ice sheets (2% of the global water). Everything else, rivers, lakes, marshes, aquifers, and reservoirs represent that remaining 1% of the Earth's water supply--and that 1% of water is what sustains human settlements and allows for agricultural expansion. The geography of this 1% is highly uneven and a huge water crisis can cause governments crumble--the fact that this precious resources has been wasted and polluted becomes more frustrating as water resources are being strained in so many places. In this article, it describes 8 major metro areas where water is being depleted rapidly -- Tokyo, Miami, London, Cairo, Sao Paulo, Beijing, Bangalore and Mexico City.

"Multi-purpose land use."
Seth Dixon's insight:
There are many videos online showing the Maeklong Railway Market, but I'll share just a few. Clearly the 8 times a day runs like clockwork for the vendors, but as this other video shows, the 8 times a day that the trains go through the market an it becomes a tourist attraction. Locally it's called "Ta-Lad-Rom-Hoob," which means The Furled Umbrella Market. My students are usually quite shocked to see how this city market in Thailand operates and this video is a usefully 'hook' for lesson on population growth, urbanization, economic development, sustainability, megacities and city planning. Questions to Ponder: Why does this system work in Thailand, but is inconceivable for the United States? How many spaces are single use spaces that remain empty most of the day? How does the both the train line and the market need to accommodate the other? Tags: Thailand, Southeast Asia, urban, land use, megacities, development, density, sustainability, planning.

we have talked about this in class and what works in one place doesn't mean it will work everywhere. This is a sign that people adapt and build there own community whatever works to survive. This is a norm for them as you do not see any panic in the people and they have a set up that was planned out. They all grab a canopy and the train as just passed by and they are already put the canopy back up. what bothers me is the food that is just laying there and the right back side is right on top of the food. for us it is a sanitation problem to them it is a business to survive. They must hear the train coming because it can not be a schedule program what would happen if the train is not on time or early? I wonder if disaster has ever struck. I mean we wouldn't hear about it but I would have to think it has happened.

Definitely a good way for multi-purpose land use. They are utilizing the space they have conservatively, they really nailed this one on the head coming up with an idea to put a market right on a railroad track. Is this concept even safe or sanitary? Most definitely not. First off, it is not sanitary because that train on a daily basis has gone through all sorts of dirt and the train is literally passing right over the farmer's food that he is still going to sell to customers. Also, probably not the safest, because the people are just inches away from the passing train and with the wrong move, they can possibly fall onto the track and they are dead. I will hand it to them though, they act in an orderly fashion and move swiftly both when it comes and when it leaves. As a matter of fact, they go on with life so well after it leaves, it is almost like the train never passed through in the first place.

"Physicist Geoffrey West has found that simple, mathematical laws govern the properties of cities — that wealth, crime rate, walking speed and many other aspects of a city can be deduced from a single number: the city's population. In this mind-bending talk from TEDGlobal he shows how it works and how similar laws hold for organisms and corporations."
Seth Dixon's insight:
While corporations rise and fall, it is quite rare for a city to entirely fail as an economic system. Huge cities have some negative consequences, but the networks that operate in the city function more efficiently on economies of scale in a way that offsets the negatives. Increasing a city's population will continue to improve the economies of scale (larger cities have higher wages per capita, more creative employment per capita, etc.). However, this growth requires major technological innovations to sustain long-term growth.

The idea that cities are just organisms that are satisfying the laws of biology is interesting. Especially because Physicist Geoffrey West brings the idea of Scalability which by definition is, the ability of a system, network, or process to handle a growing amount of work in a capable manner or its ability to be enlarged to accommodate that growth. What’s mind blowing to me is that the system that is referred to here is human interaction. We create these cities through our interaction and experience. With a growth rate of 1,000,000 people every year the math adds up to an agreeable 15% rise in income levels, patents, and super creative people every year which is undoubted a win for civilization and society. But with that we must keep in mind also this means a 15% increase in things like deadly disease, crime, poverty, and ecological issues leading to further degradation of our planet. This unbounded growth means the system is destined to collapse. The math behind cities doesn't lie if we don’t prepare cities have a fate to die like every other organism in Biology. So it is up to us to create and innovate to sustain this growth and avoid the collapse. But we must do so at a forever increasing pace. Which subsequently is also part of another system predetermined to collapse. What I mean is what happens when we cannot innovate fast enough to sustain this growth? - Caleb Beckett

Scientists have issued a new warning to the world’s coastal megacities that the threat from subsiding land is a more immediate problem than rising sea levels caused by global warming. A new paper from the Deltares Research Institute in the Netherlands published in April identified regions of the globe where the ground level is falling 10 times faster than water levels are rising - with human activity often to blame. In Jakarta, Indonesia’s largest city, the population has grown from around half a million in the 1930s to just under 10 million today, with heavily populated areas dropping by as much as six and a half feet as groundwater is pumped up from the Earth to drink. The same practice led to Tokyo’s ground level falling by two meters before new restrictions were introduced, and in Venice, this sort of extraction has only compounded the effects of natural subsidence caused by long-term geological processes.

Casey Lysdale's curator insight,
November 28, 2016 9:43 AM
Could subsistence in megacities becoming a bigger threat than sea level rise? The population rise caused an increase in groundwater extraction practices which made the ground sink over six feet in Indonesia's largest city. The solution is to stop pumping groundwater and seek alternative forms of obtaining drinking water. Effects of land subsistence combined with rising sea levels can leave many coastal cities into project Atlantis.

Without a question, we are living in an urban era. More people now live in cities than anywhere else on the planet and I’ve repeatedly argued that cities are our most important economic engine. As a result of these shifts, we’re seeing megacities at a scale the world has never seen before.

Mexico City has been the economic center of Mexico for a long time and is a true primate city. "Wealth accumulation in Mexico City has historically been concentrated in the hands of a few. In colonial times, the elite was mostly composed of Spanish-born immigrants who held high-ranking offices or worked as business owners or export-oriented merchants. Later, the wealthy were those who owned large estates known as haciendas…It is estimated that around 40 percent of Mexico’s income is owned by just 10 percent of its population, while 52.3 percent of Mexican citizens live in poverty."

This video is an introduction to a fascinating (Spanish language) website and project that uses GPS-tagged vultures to map out the urban trash hot-spots in Lima, Peru. We look at vultures as the dregs of the food chain and ascribe moral filthiness to the species (just think of any number of movie, literary, and cultural references), but they are simply filling an ecological niche. This mapping project is a way to use vultures nature in a way that allows for humanity to fix our trash production/disposal problems.

It is a real shame that China has let pollution go this far in its country. It really goes to show the sacrifices they are willing to make in order to be a major global economic power. Unfortunately for them this kind of action and rapid growth by cutting corners is what will likely stop them from becoming a major power (due to fast resource exhaustion and loss of environmental resources due to pollutants over time as well as species). The issue will likely remain unsolved due to the Chinese governments lack of concern. Hopefully China's slow shift to a consumer market will provide pollution relief as the factories leave for elsewhere (likely Africa).

It is astounding the amount of growth this one city has had in one decade and reminds me of some of the rapid development within the Middle East since the 70s which transformed cities like Dubai. Ecologically like most of what China does it is a disaster but fascinating from a development one. Unfortunately the article doesn't offer a population so that it could be compared to Tokyo's since a size comparison was done in terms of land use. Hopefully China will find a sustainable method of growth because if city continue to grow like this it will be surprising if they could maintain stability. I personally thing this rapid growth is dangerous and like India they likely won't be able to keep up. Additionally since China's economy is very reliant on this type of growth it is concerning to think of what may happen to many of these cities when the growth they rely on stops.

Dhaka is the capital of Bangladesh and (as I often tell my students) it is the biggest city that nobody has ever heard of. The infrastructure is so incredibly limited that traffic jams cost the city an estimated $3.8 billion in delays and air pollution. This is an excellent article to explore some of the problems confronting megacities.

What's amazing is the way the pedestrians go about their business walking in between cars and buses. A person would think it would be faster and healthier to walk. It costs 3.8 billion dollars in delays and air pollution why not spend that money on Traffic devices. I am assuming that it is not money wise but economically wise they are talking about the cost factor. If that is the case the city would have to front the money to pay for the traffic devices and recoup the money from the businesses that benefitted from the insertions of traffic devices. Environmentally it would be a good thing so all those people are not breathing in all the pollution which must cause health issues.
Its amazing how much traffic can affect air pollution, especially in such a small place. Dhaka is heavily populated, traffic in this small but heavily populated community is very stressful, even to look at in the photo provided above. I can't imagine living in such a heavily populated area. I guess you can compare it to downtown New York City. However the pollution is more intense in Dhaka than it is in NYC.
This is a prime example of a megacity and the population that it cohabits the city. The huge populaiton that is se densley populated in such a small area creates for a large traffic and pedestrian issues. After watching the video you would think that there would be more accidents but living in a city like this you would get use to the population ways and learn the ways of life.

In 2011, one of the AP Human Geography Free Response Questions focused on identifying if the rank-size rule applied the urban hierarchy of a country (Mexico), or if a primate city dominated the network of metropolitan regions. To prepare people to understand the rubric, I put together this presentation, based primarily on my time researching in Mexico City (download the PPT file to access my notes for each slide). The problems with primate cities are hardly unique to Mexico City; this additional BBC article bemoans Britain’s lack of a true second city, arguing that London’s shadow looms too large for sustained national development outside of the primate city.

This slide show teaches you what primate cities are and gives you an example and background of one. It teaches you about Mexico City and the characteristics of it.
This article relates to Unit 7: Cities and Urban Land Use because it teaches you about primate cities. Primate cities have disproportionately large populations and is over two times larger than the next largest city in the country
This power point shows the negative and positive factors accounting for Mexico City being a Primate city.
The pp gives insight on how Primate cities such as Mexico have a disproportionally large population, resulting in an unbalanced economy.
Mexico City is a primate city, since it's population is significantly larger than any other city in Mexico. Primate cities are only deemed primate cities if they are double or more the population of the running up city.
Primate cities show population distribution since a large majority of the population is centralized around one area.
