Mega cities - managing traffic challenge in Lagos.
Are you ready to share the planet with 7 billion people? Current projections estimate that this population milestone is only months away. Along with a rapidly growing world population, the wave of urban growth continues, causing cities to swell and new metropolitan centers to emerge. As of 2008, more than 50 percent of the world’s population lived in cities for the first time in history. In addition, a recent UN-Habitat report indicated that urbanization has become unstoppable and that by 2050, over 70 percent of the world will be in cities! It seems the world took Petula Clark’s song Downtown seriously.
Are mega regions sustainable? Is the Western city model the best one to implement even if it is “greened”? Are we going to continue pushing the envelope with a complete disregard for any constraints or consideration of the consequences? Will this help force a collapse as outlined in Limits To Growth: The 30-Year Update: http://www.amazon.com/Limits-Growth-Donella-H-Meadows/dp/193149858X ? Or is there a new paradigm just around the corner? We may be standing at the precipice. Let's figure out the best way to survive the projected nine billion population by the year 2050.

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.
The cities of the world are facing multiple challenges (space, health, jobs and a conflict with the nature amid threats of climate change and global warming). Will we be able to build self-sufficient mega cities?
