If that's what is predicted for 2025, how populated will our world be by 2050? Scary to think about.
Seth Dixon's curator insight, January 16, 2013 9:28 AM

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.

Urbanization and Megacities: Jakarta

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

Lauren Stahowiak's curator insight, April 16, 2:16 PM

In megacities, such as Jakarta, urbanization brings about many problems for local residents. The areas are crowded and residents get little to no income. An Australian organization works to help the people of Jakarta by giving them advice,food and helping where necessary. With this help, families are able to keep their spirits higher and hope that their children will live better lives than the ways that they were brought up.

Joseph Thacker 's curator insight, April 18, 5:10 PM

Jakarta is the capitol of Indonesia and now has a population of over 28 million. Urbanization is bringing serious problems to Indonesia’s only mega city, such as poor access to clean water and housing, and overpopulation. Some people, including the young woman in this video are living with 16 or more people in one house. It seems the city is not providing enough affordable housing for its residents.

Tracy Galvin's curator insight, May 1, 11:25 AM

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.

This is a good youtube link on Urbanisation

Tracy Galvin's curator insight, May 1, 11:44 AM

It is very sad that people have to move to a polluted, crowded mess of a place in order to get a better life. The man says at the end that if they can make it work in Dhaka, they could make it work in any city but the beginning is too monumental to get over. I think that maybe some government control over the outer limits of the city and offering a place nearby with some resources may allow more control over the growth of the city at least temporarily.

Jess Deady's curator insight, May 4, 5:50 PM

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.

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.

The rise of Megacities - an interactive slide show experience

The rise of Megacities - an interactive slide show experience | Year 12 Geography | Scoop.it

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.
