Accepting his 2005 TED Prize, photographer Edward Burtynsky makes a wish: that his images -- stunning landscapes that document humanity's impact on the world -- help persuade millions to join a global conversation on sustainability.
Many cities are large; the rate at which these ten cities highlight a distinct spatial pattern and separate them from the rest. Which regions have the fastest growing cities? Which regions don't? Why geographic factor account for the rapid growth?
The rapid increase in the number of cities home to more than 10 million people will bring huge challenges … and opportunities...
It's not just that more people now live in cities than in the rural countryside (for the first time in human history). It's not just that major cities are growing increasingly more important to the global economy. The rise of the megacities (cities over 10 million inhabitants) is a startling new phenomenon that really is something we've only seen in the last 50 years or so with the expectation that the number of megacities will double in the next 10 to 20 years (currently there are 23). This reorganization of population entails wholesale restructuring of the economic, environmental, cultural and political networks. The urban challenges that we face today are only going to become increasingly important in the future.
A good video about global population trends since 1950. The is rich with charts, maps and data (from Hans Rosling it would appear) many about accelerated population growth, total fertility rates. China, Iran, South Korea and France are all individually showcased to show how global patterns were at play within local settings.
Eighty-two years after the original development of the four stage Demographic Transition Model (DTM) by the late demographer Warren Thompson (1887-1973), the cracks are starting to show on the model that for many years revolutionized how we think about the geography of our global population.
"In 1979, the National Population and Family Planning Commission in China enacted an ambitious program that called for strict population control. Families in various urban districts are urged to have only one child—preferably a son—in order to solve the problems related to overpopulation. What has happened since then and what are its implications for the future of China?" This is an excellent infographic for understanding population dynamics in the world's most populous country.
Rome was the first city with one million residents, with that occuring in 5 BC. Over a thousand years later, London and Beijing joined that group as industrialization became the impetus for wide-scale urbanization. Today we are seeing an explosion of "million cities" throughout the world.
The West African state of Niger is now the worst place in the world to be a mother, a Save the Children annual report says.
Gender, demographics and development are the main geographic themes that run through this report. As many countries prepare to celebrate Mother's Day, the Non-Governmental Organization Save the Children considers the geography of motherhood and the difficulties in raising a healthy, educated, well-fed child with economic opportunities for the future. The variables used in the index included factors such as health, education, economic status and nutrition as key indicators that would be pertinent to motherhood.
The most difficult place to raise a child according to the report are: 1) Niger, 2) Afghanistan, 3) Yemen, 4) Guinea-Bissau and 5)Mali. The best places to raise healthy, education children are: 1) Norway, 2) Iceland, 3) Sweden, 4) New Zealand and 5)Denmark.

At current growth rates, sub-Saharan Africa, which now makes up 12 percent of the world’s population, will account for more than a third by 2100.
Africa is the world's fastest growing region and consequently it is an incredibly young (demographically speaking) region. This video show key reasons (primarily cultural and economic) for the population growth within Africa. How does the demographic transition model apply to Africa?
China's Urban Population Now Exceeds 50% of Population.
China has historically been a predominantly rural country; a major part of the economic growth of the last few decades has been driven my a push towards urbanization. Now that China is predominantly an urban population, what will that been for resource consumption, development and global economics?
We often talk about life expectancy data at the national level; this simplification has a great deal of utility but obscures regional distinctions within a country. Some counties in the United States have life expectancies on par with Japan (84), while the worst off counties are more similar to Indonesia (69). Even more startling, in 661 counties, life expectancy stopped dead or went backwards for women since 1999. This is a dramatic look at the importance of scale within any geographic analysis to arrive at reasonable conclusions. So let's start looking at local demographic data instead of just nationally aggregated data.

According to the United Nations, by the year of 2050, 70% of the world’s population will be living in urban areas. So what will the city of the future look like?
6 TED Talks to get you thinking about how you would alter the cities of the future to make them better equipped for a world of 9 Billion by 2050. Remember it has been estimated that roughly 6 billion people will be living in cities by 2050. How do we prep our megacities of the future for this rapid population change? What problems will we face? How will "The West" face these problems? "The Rest"?
