Feature Story August 14, 2012 The year 2011 was a historic moment in the urbanization of China, as its urban population exceeded its rural population for the first time. About 350 million new urban residents are expected to migrate to cities over the coming 20 years. Urban development on such a scale is both a challenge and an opportunity for urban transport. A challenge, as current trends are unsustainable both at local and national level. Locally, the rapid growth in car ownership has enabled greater personal mobility for many but has also brought traffic congestion, accidents, and air pollution. Slow and congested transport systems are beginning to stifle the efficiency of the urban economy. The construction of new roads to accommodate traffic leads to urban sprawl and accelerated traffic growth and hampers the mobility of those who do not own a car. Nationally, excessive conversion of farmland for urban development consumes scarce land resources and impacts the country's ecological systems. Rising fuel consumption also endangers the nation's long-term energy security, while growing emissions from urban transport render the national objectives of CO2 reduction difficult to achieve. But this rapid urbanization also represents an opportunity, as the recognition of urban transport's spillover effects has led to a new policy emphasis on public transport priority and sustainable urban transport development.

Siu Yu Lau, Stephen Gonzalez Martinez Paula In: ACE©, AÑO 7 núm.20, OCTUBRE 2012 China is going through one of the most dramatic social and cultural transformations in its history.

Invention, reinterpretation sometimes even revolution, never represent a step further as they did in the XXI century theoretical thinking. To engage architectural thoughts with the booming economy could contribute to the definition of a contemporary Chinese architecture, far from the generic city, in a society that has evolved from pre-modernism to post-industrialism in a short period of time. Through the analysis of Hong Kong, and a series of case studies, a conclusion to this scenario is sought.
