There is little doubt that urbanization is becoming the new norm in many developing countries. One need only look at what is happening in India, China and now Africa as these countries are experiencing a significant shift of their vast populations from the rural setting to the urban centers. Cities like Delhi and Mumbai are becoming so big that it is increasingly more difficult to move around the city and their population densities are one of the highest in the world.1 According to UN estimates, Lagos in Nigeria is on pace to be the third largest megacity by 2015 after Tokyo and Mumbai.2 China, on the other hand, boasts the most megacities in the world (four).3
