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.

This is a great introduction to the demographic explosion of the slums within megacities.  This is applicable to many themes within geography.   

Sarah Cannon's curator insight, December 14, 2015 10:20 AM

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. I can't imagine not being able to access clean drinking water or lacking food. The people in Dhaka endure so much their whole lives, a good percentage of them will always live in poverty.

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.

The Insane Growth Of China’s And India’s Megacities Mapped Through Satellite Imagery

The Insane Growth Of China’s And India’s Megacities Mapped Through Satellite Imagery | Year 12 Geography | Scoop.it

These charts--made with information from weather satellites scanning the ground--show how wide and how tall cities around the world have grown. What’s happening to the size of cities in Asia will blow your mind.

 

Faced with the incomprehensible scale of worldwide mega-urbanization, observers have alternately fallen back on sheer numbers or city comparisons to drive home the speed at which cities in the developing world are growing. For example, New York University’s Shlomo “Solly” Angel projects the world’s urban population will double in 40 years, while urban land cover--including everything from skyscrapers to slums--will triple in size during that span. Grasping to put such numbers into context, the McKinsey Global Institute estimates China will build the equivalent of New York every other year for 20 years, while India needs to add the equivalent of a Chicago to its building stock annually.

 

The mind reels, but such comparisons tell us little about the truth on the ground--is the urban future of India more likely to look like Chicago or Dharavi (Mumbai’s famous slum) or something else completely? A satellite designed to measure ocean winds offers us a clue.

If that's what is predicted for 2025, how populated will our world be by 2050? Scary to think about.

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.

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.

Sixty-two years ago New York and Tokyo were the world's only megacities – 'urban agglomerations' with over 10 million residents. Now in 2012, there are 23, and by 2025 the UN predicts nine new megacities in Asia will bring the total to 37. All but eight will be in the developing world – and the quality of life for millions will be determined by the quality of their cities. This interactive map shows the 100 most populous cities as of 2012 according to the UN.

Megacities pose serious health challenge

Megacities pose serious health challenge | Year 12 Geography | Scoop.it

Rapid urbanization will take a heavy toll on public health if city planning and development do not incorporate measures to tackle air pollution, warns a report launched in Beijing last month.

The report1, compiled by the World Meteorological Organization (WMO) in Geneva, Switzerland, and the International Global Atmospheric Chemistry (IGAC) project in Boulder, Colorado, was launched as part of the IGAC Open Science Conference on Atmospheric Chemistry in the Anthropocene. A striking point in the report, says Liisa Jalkanen, head of the WMO’s Atmospheric Environment Research Division, is how quickly megacities — metropolitan areas with populations of more than 10 million — are rising in developing countries.

There are now 23 megacities in the world, compared with just two 60 years ago. Just over half of the population currently dwells in cities, and with the urban population expected to nearly double by 2050, that proportion is projected to approach 70%. “Almost all this growth will take place in the developing world,” says Jalkanen.

Max Minard's curator insight, May 26, 2015 11:21 PM

This article highlights major health issues that result from the increase in mega cities. Resulting form rapid urbanization, mega cities continue to grow and pose issues such as an increase in pollution. As the article states, "there are now 23 mega cities in the world." and "just over half of the population currently dwells in cities." Nations such as China and Japan have already experienced large amounts of urbanization and are currently struggling in tackling the increasing rates of air pollution. I personally think city planners and developments need to focus on controlling this issue along with researchers coming up with a less toxic renewable resource to use for energy.
