Essay What are the factors behind the rise of megacities

What are the factors behind the rise of Mega Cities, and to what extent are these urban areas sustainable? Megacities, defined by population, have at least 10 million inhabitants. In recent years, megacities in the developing world have grown rapidly with little or no planning. As a result, they face cries of infrastructure, poverty and unemployment. The driving force for the rise of megacities is mass urbanisation between rural – urban areas, as well as rates of natural increase that are higher in urban than rural areas.

Economically, megacities thrive. Most of the time mega cities are also world cities, which mean they are resource and learning centres. This strongly suggests that business and global trade is strong between other countries (that they have high levels of synergy). Regarding how socially sustainable megacities are, lots is being done to make sure that they are socially sustainable. For example, in Jakarta there are traffic problems but they are being faced to rid the city of pollution and congestion. The city has launched a ‘three to one’ policy, demanding that every car on major thruways carry at least three passengers when passing through special zones between 4:30pm to 7:30pm.
