The Rise of Megacities

The Rise of Megacities | Educació de Qualitat i TICs | Scoop.it
By 2025, the developing world will be home to 29 megacities.

 

Through this interactive mapping feature with rich call-out boxes, the reader can explore the latest UN estimates and forecasts on the growth of megacities (urban areas with over 10 million residents).  These 'cities on steroids' have been growing tremendously since the 1950s and present a unique set of geographic challenges and opportunities for their residents.

Download the data yourself as a CSV file and your can import this into ArcGIS online and symbolize your map with any of the columns in the dataset.

Very cool!

World cities and megacities - Presently , the mega cities of the world have to have a population of at least 10,000. Many cities are very near the minimum to be considered a mega city, but are not quite there. By 2025, the developing world, as we understand it now, is estimated to be home to 29 megacities.

The Real World at Night

The Real World at Night | Educació de Qualitat i TICs | Scoop.it

Earlier I have posted the classic image of "Earth Lights at Night," and discussed the classroom uses of the image.  This cartogram helps take that analysis one step further.  This cartogram helps students to visualize the magnitude of population (with the cartogram adjusting area for population) and then to see the patterns of energy use, global consumption and urbanization with in a new light.

This map is obviously not the actual size of countries, but it is in a way. The populations of China and India are so great compared to the rest of the world and this map shows that.

Flexible Urban Planning

mixed used train-tracks/market place...

 

I've used similar videos in my classes and students are usually quite shocked to see how a city like Bangkok, Thailand operates.  I've used this as a 'hook' for lessons of population growth, urbanization, economic development, sustainability, megacities and city planning.

On the one hand this disturbed me. All I kept thinking when I saw the people go back on the tracks is that they could easily be killed.In fact, I wonder how many accidents have ever occurred near this area. All it would take is some sort of malfunction on the train in which the horn wasn’t sounding to provide ample warning or someone gets in another person’s way so there isn’t enough time to close down the shop. On the other hand, this made me realize just how efficient a population could become at using space. Everything was timed so that the entire area moved out of the way without an issue. So rather than let any land go to waste, the area uses it despite the risk to its population. Though it really isn't like the population has a choice though. So in instances where there is such overpopulation, it is interesting to see how well the society can adapt to the phenomenon. I do wonder what would happen if the country becomes more developed and the population declines. Would this type of land continue in the future or be disband? I know that in our country there are many laws that would make this illegal, but our country also has the space avoid developing the land in such a manner. When comparing it to the laws of the United States, I would think the country would eventually drift away from this use of land when possible. However, now that I watch the video, I have a new appreciation for maximizing land and I hope that the efficient could continue. Just in a less scary manner.

Talk about using every inch of space available to you.  I find this video crazy not only because of the safety hazards, but just how people seem to go about this like it is normal.  This would never take place in America!

Felix Ramos Jr.'s curator insight, May 7, 2015 1:29 PM

An absolute amazing dynamic is seen in this video.  To say that Bangkok is trying to use most of its open space up would be an understatement.  In developed countries, you would not only never see this happen but you would not even see a thought of doing something like this.  There are violations every where you look.

Visualizing Regional Population Statistics

It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West.

 

This is an excellent video for population and demographic units, but also for showing regional and spatial patterns within the global dataset (since terms like 'overpopulation' and 'carrying capacity' inherently have different meanings in distinct places and when analyzed at various scales). It is also a fantastic way to visualize population data and explain the ideas that are foundational for the Demographic Transition Model.

This video describes and explains how we got to a population of 7 billion people so fast

Mohamed Mohamed's curator insight, October 13, 2014 4:04 PM

It also uses water to demonstrate it.

Mapping Population Density

Mapping Population Density | Educació de Qualitat i TICs | Scoop.it
I found these cartograms from an article in the Telegraph and was immediately impressed. The cartograms originated here and use data from the Global Rural-Urban Mapping Project as to create the int...

 

This series of cartograms shows some imbalanced populations (such as the pictured Australia) by highlighting countries that have established forward capitals.  Question to ponder: Do forward capitals change the demographic regions of a country significantly enough to justify moving the capital?

Interseting way to visualy map population density.

Lona Pradeep Parad's curator insight, May 28, 2014 7:28 PM

It's a creative and vial way to map population density. 

MissPatel's curator insight, December 16, 2014 3:24 AM

This is from 'worldmapper' - it is a great sight to help you understand using technology the most densely populated areas of various countries. What do you think they are?

Beyond 7 Billion

Beyond 7 Billion | Educació de Qualitat i TICs | Scoop.it
After remaining stable for most of human history, the world's population has exploded over the last two centuries. The boom is not over: The biggest generation in history is just entering its childbearing years.

 

The Los Angeles Times has produced an in-depth interactive feature centered around the impact of an increasing global population.  With videos, population clocks, narrated graphics, maps, photos and articles, this is treasure trove of resources that cuts across many disciplines.
