From megacity to metacity

From megacity to metacity | Geography Education | Scoop.it

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."

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.

Thirsty Yet? Eight Cities That Are Improbably Running out of Water

Thirsty Yet? Eight Cities That Are Improbably Running out of Water | Geography Education | Scoop.it
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.

London's Dominance Becomes A British Election Issue

London's Dominance Becomes A British Election Issue | Geography Education | Scoop.it

"London completely dominates the political, cultural and economic life of the U.K. to an extent rarely seen elsewhere. That imbalance has been an issue in the run-up to Thursday's election."

Seth Dixon's insight:

The problems with primate cities are hardly unique to London (see here resources for teaching about primate cities using the example of Mexico City).  The lack of a balanced urban hierarchy that we would see in countries where the rank-size rule applies is a political problem as stated in this NPR podcast.  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.

Blake Joseph's curator insight, May 6, 2015 6:02 PM

I remember seeing a road map of the United Kingdom once and wondering why almost every single road eventually seemed to make its way to the massive urban sprawl of London in the country's southeast. Even cities as far away as Inverness in Scotland or Belfast in Northern Ireland seemed to inevitably revolve around the massive capital. Having such a dominance on the country, I can see why other distant communities are gradually losing interest in the political and economic influences London still has on them, especially if other closer urban centers are greatly growing in population and influence. The recent election for Scotland's independence from England shows that even today many people are looking to branch out away from London's reach, and that these reasons are perhaps not totally influenced by historic tensions and rivalries between the two places. Populations centers like Birmingham and Manchester have grown immensely in the last decade, and with that has came a growing independent sense of culture and identity as well. Residents in smaller towns and villages feel that these other closer  urban areas would be a better representative of them in country-wide politics than distant London. Some of these distant communities are nearly 500 miles away from London. That is like Detroit, Michigan being politically and economically dominated by New York City. Even with London being massive in size and influential reach, I can see why far away towns in the U.K. don't always consider London too important.

China’s Pearl River Delta overtakes Tokyo as world’s largest megacity

China’s Pearl River Delta overtakes Tokyo as world’s largest megacity | Geography Education | Scoop.it
Several hundred million more people are expected to move to cities in East Asia over the next 20 years as economies shift from agriculture to manufacturing and services, according to a World Bank report
Seth Dixon's insight:

Cities in this region have experienced spectacular growth; they are at the heart of China's manufacturing and exporting boom.  For example, Shenzen was a small city with about 10,000 residents in 1980 but is now a megacity with over 10 million people.  China's SEZs (Special Economic Zones).  Cities that were once separate entities have coalesced into a large conurbation and if they are counted as one, it's now the largest metropolitan area.  Cities like London and New York become global cities over hundreds of years--this happened in one generation.  Click here for 5 infographics showing East Asia's massive urban growth.

Seth Dixon's insight:

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.

Gene Gagne's curator insight, November 18, 2015 1:09 PM

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.

Sarah Cannon's curator insight, December 14, 2015 9:50 AM

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.

Matt Ramsdell's curator insight, December 14, 2015 3:35 PM

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.

I thought this article was good as it gave information on how the world as we know it is growing and cities are popping up everywhere. Developing countries are seeing a large increase in growth and with that comes the growth of cities. With this, more megacities will be born and hopefully the quality of life increases with life in cities.

Beijing's Pollution

Beijing's Pollution | Geography Education | Scoop.it
Seth Dixon's insight:

We've all heard stories about the horrible air quality in Beijing (especially during the 2008 Olympics).  Here's a picture of Beijing by Tom Anderson that I find riveting.  The skies are obviously polluted but this image shows two competing cities that are vying for control of China's future. In the foreground we see a cosmopolitan capital that is sophisticated and technologically advanced, engaged in the great connections that come from industrial growth.  On the other side we see the industrial city that is recklessly producing copious amounts of consumer products with little regard for the environment or worker safety that can be seen as the dirty side of globalization.  Both images are true reflections of China in the 21st century and the tension between the two will be one of China's great issues in the foreseeable future.

Nicole Kearsch's curator insight, November 24, 2014 11:40 PM

This picture taken by a photographer with the perfect lighting is brilliant....that is, if you're into deceiving people that the pollution from these power plants stays away from the higher class businesses and residences.  Looking at this picture you see the smoke coming from the power plant in China far in the distance creating a yellowish hue that could be thought to be from the sun.  Then closer in the scene we see what appears to be businesses and potentially some peoples homes.  This area is in a totally different color from the yellow we see to be associated with the pollution from the power plant.  Here we see a blue, commonly associated with clean water, covering the entirety of this area.  With the difference in colors these places seem to be as different as possible from each other.  In reality though, smog doesn't just stay in one area of the city where it is produced, but spreads throughout the entirety of a city.  There are no restraints on where the pollution can and can't be, it is free flowing into communities where people work and live.  If you're trying to sell a house here this picture wouldn't be a bad idea to use, although most natives aren't oblivious to what is really going on.

Hector Alonzo's curator insight, December 15, 2014 8:00 PM

This picture is interesting to say the least, it depicts two different cities, even though it is the same city. the picture does a good job at showing the major problem that pollution is causing to Beijing. While showing a smog surrounded city behind a clean, yet clouded looking city, drives this point of pollution home and raises the question is putting large factories and toxic fumes in the air, more important than the well being of your citizens?

Rapes Cases Show Clash Between Old and New India

Rapes Cases Show Clash Between Old and New India | Geography Education | Scoop.it
A boom and social change are pitting young working women in the city against men from conservative villages.
Seth Dixon's insight:

The recent resurgence of this issue had me looking through the archives and stumbled upon this 2011 article.  As urban expansion is booming in many Indian cities, the modern city expands into the countryside.  The cultural values of these two demographic groups are quite distinct.  Young, educated women are part of the modern cities' workforce but in many conservative, traditional Indian villages, women working outside the home are seen as "lacking in virtue."  In many of the recent gang rape cases, the perpetrators are less educated young men from surrounding villages and the victims are well-educated young working women that are a part of the new city.    


Public spaces, especially at night, are seen as masculine spaces in most traditional societies.  One of the mothers of an accused rapist succinctly explained this mindset thusly: "If these girls roam around openly like this, then the boys will make mistakes."  This is seen as 'Eve teasing,' where women are perceived as responsible for the violence committed against them to maintain social order.  As another article hints, the outrage that this incident ignited could lead towards long-term change in Indian society.   


This other NY Times article op-ed states, "India must work on changing a culture in which women are routinely devalued. Many are betrothed against their will as child brides, and many suffer cruelly, including acid attacks and burning, at the hands of husbands and family members.  India, a rising economic power and the world’s largest democracy, can never reach its full potential if half its population lives in fear of unspeakable violence."

Jessica Rieman's curator insight, April 23, 2014 1:37 PM

This issue is very distrubing. First of all it talks about the poor inocent women and girls who leave their house so they are automatically a victim and should be forwarned that they will be hurt if leaving thie house like as if they should be resticted to their home life and never leave. This would be demonstrated as the old India but they are living or rying to live in the New India where the Women in this soicety should nto be subjected to these kinds of crimes. For example something that really took me was "The accused are almost always young high school dropouts from surrounding villages, where women who work outside the home are often seen as lacking in virtue and therefore deserving of harassment and even rape." And then this quote by one of the accused mothers; "“If these girls roam around openly like this, then the boys will make mistakes,” the mother of two of those accused in the rape said in an interview, refusing to give her name."" Like come on get your stuff together, you should have raised your children better than this.  I have to wonder what this society thinks and whether or not people are questioning what kind of society they are living in and if this society is pressured by the values of the sexes.

Jess Deady's curator insight, May 4, 2014 9:06 PM

Getting away with rape in any country is absolutely disgusting. Especially in India where women have been brutalized with no punishment to the predator, these women have a right to stand up for themselves. Being stalked and raped is something that the police need to get a grip on happening to their citizens.

Kendra King's curator insight, March 28, 2015 8:37 PM

It is hearting to see the police force in the modernized area taking such a strong stance. As the article showed it is greatly needed because the reason rape largely happens is because the traditional aspects of Indian culture continue on strongly in the village areas. These men were told for the longest time that women cannot amount to anything and for them to act free is wrong. This type of thinking is heavily engrained into the members of the society so they won’t just stop acting this way on their own accord. Arresting and convicting these men will send a message that their actions are not tolerated and aren’t right despite what they were taught.

 

 It also amazes me that this stance exists because the modernized area were also told these stories at one point too. The only explanation I have for the differences is that the more modernized areas are more welcoming of the freedoms seen in the West. To be clear though, the freedoms are more of a western trait. Thus globalization in this instance might have actually helped the positive result of the police force come about because of the positive influence seen in the Western countries economy and life style when they let women have more freedom.

 

Unfortunately, globalization can’t completely solve rape just yet. The article ends by asserting that to report rape “is a very difficult thing in the Indian context.” Yet, reporting rape anywhere is hard to do. In fact, the mention of 1 in 10 under reported rapes is a statistic similar to that of the United States. Similarly, many victims will refuse to cooperate or even contemplate taking their own life to avoid testimony (in fact many do). In either situation, most rape victims feel they lost their “honor.”  I am not sure when reporting rape or how reporting rape will ever become any easier. However whichever country can figure it out will need to show the rest of the world how. As I do look forward to the day that globalization could decrease rape on a large scale.

Nicholas A. Whitmore's curator insight, December 16, 2015 11:03 AM

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).

Sarah Cannon's curator insight, December 16, 2015 6:39 PM

It's horrible to see China come to this. Soon, air pollution will be just as bad everywhere else if it is not stopped. We, everyone, has to do something to stop air pollution. This world is polluted enough. Stop air pollution so future generations can have a chance to have a good life and not have to worry about PM levels are in the air on a daily basis.

Maeklong Railway Market

"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?

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.

This is insanity!! I've never seen anything like this! I always wondered why people who live in such squalor stay living in the area. If you have to pack your house up so a train to come through it might be time to move.

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.

The surprising math of cities and corporations

"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.

Not surprisingly the DNA of cities is a follow-up of human DNA and understanding this will explain and predict how the body of a city will develop!

SRA's curator insight, April 16, 2015 2:10 AM

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?

The world's megacities that are sinking 10 times faster than water levels are rising

The world's megacities that are sinking 10 times faster than water levels are rising | Geography Education | Scoop.it
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.

Primate Cities: Mexico City

http://geographyeducation.org/2014/05/05/primate-cities-mexico-city/

Seth Dixon's insight:

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 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.

Anna Sasaki's curator insight, May 27, 2015 7:45 AM

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.

The Growth of Megacities

The Growth of Megacities | Geography Education | Scoop.it

"For the first time in human history, more of the world’s 6.8 billion people live in cities than in rural areas. That is an incredible demographic and geographic shift since 1950 when only 30 percent of the world’s 2.5 billion inhabitants lived in urban environments.


The world’s largest cities, particularly in developing countries, are growing at phenomenal rates. As a growing landless class is attracted by urban opportunities, meager as they might be, these cities’ populations are ballooning to incredible numbers.


A May 2010 Christian Science Monitor article on “megacities” predicted that by 2050, almost 70 percent of the world’s estimated 10 billion people—more than the number of people living today—will reside in urban areas. The social, economic and environmental problems associated with a predominantly urbanized population are considerably different from those of the mostly rural world population of the past."

Whitney Souery's curator insight, May 28, 2014 6:48 PM

The majority of megacities are in the developing world, with the exception of places like New York and Tokyo, best showing how the face of the world is changing. Developing countries are on their paths to becoming major powers, such as Calkutta for example. As an enlarging city, more and more citizens are flocking to the abundance of jobs in the city which thus increases India's development as a result of the growing city and thus leads to a cycle of growth as demand for more jobs increases as the city grows. Megacities are thus a symbol of the developing world and can be used in human geography as symbols of development.

What Pollution? Hong Kong Tourists Pose With Fake Skyline

What Pollution? Hong Kong Tourists Pose With Fake Skyline | Geography Education | Scoop.it
Picture this: Tourists visiting one of your city's most prominent attractions are unable to see it because of smog, haze and a bevy of other airborne pollutants. What's the solution?
Seth Dixon's insight:

Pollution is becoming ubiquitous in our urban environments.  If your primary concern is the environment, it is clear that this situation in Hong Kong must be changed.  But what if the environment is not the concern of policy makers?  What economic and planning arguments could you make in favor of a more sustainable course?

Jared Medeiros's curator insight, April 22, 2015 7:17 PM

Major cities in the world should take a deeper look into controlling pollution problems in their cities.  At some point, these places will no longer attract people to live in these areas, thus lowering the impact that these industries may have.  But as long as people are still living here by the millions and there is tourism, and buisness is booming, nothing will be done about the issue.

Summer reading KQ4: pollution, smog, megacity, sustainability

Mark Hathaway's curator insight, November 25, 2015 6:22 AM

Pollution is a huge issue facing both Hong Kong, and the rest of China in general. So far the government  has done little to actually combat the problem. The Chinese governments response has been to pretend that the problem does not really exist. A fake skyline can just erase the problem. In reality dealing with the pollution issue would actually help the Chinese economy. When people seek to go on a vacation, they are seeking a destination that is clean and safe. Who wants to visit a place were, you have to ware a mask to prevent the breathing in of armful chemicals. A cleaner less polluted china would lead to an expanded tourism industry.

Urbanization and Megacities: Jakarta

"This case study examines the challenges of human well-being and urbanization, especially in the megacity of Jakarta."

Seth Dixon's insight:

Megacities are growing, especially in the developing world.  This rapid population growth leads to serious strains on many resources and the infrastructural capacities which leads to some dismal living conditions among the urban poor.  World Vision Australia works to assist and empower many of those without access to these important amenities.  Download the lesson as a PDF here

It is nice to see an organization that is not just blindly giving resources to people in need but actually empowering them and training them to be able to get the things they need through work. The women in this story describe how they have learned to make and sell things in order to take care of their families and they describe how empowering that feels.

mega cities Jakarta

Mark Hathaway's curator insight, November 28, 2015 6:53 AM

Megacities are beginning to populate the entire globe. In the developing world, more and more megacities are beginning to form. Jakarta Indonesia is an example of a rising megacity. This rapid urbanization has placed a special burden on the resources and local economies of many developing nations. This areas are not prepared to deal with the rapid population growth associated with the development of a megacity. This strain placed on the local areas, will often lead to terrible living conditions for the lower classes of society. Sanitation will often become a major issue in many of these megacities. Large portions of the population will often lack a proper sanitation system. The lack of proper sanitation will lead to the onset of deadly diseases. The effects of rapid urbanization can be deadly, for those living in the pooper regions of society.

To be a megacity like this, you have to conform to urbanization. There is no possible way to have such a populated and crowed city with farmlands around. This is a place of business yet residential areas, it also is where the marketplaces are and where kids go to school. Megacities need to be a part of an urban society in order for them to stay afloat.

I can't image or even relate to the experience of living in a place like this. With rivers polluted right outside your house. And those rivers are what people bathe in and wash their clothes.
