摘要：According to the United Nations, the world will need to build new cities and/or expand existing cities to accommodate about 1.6 billion additional urban residents by 2030. This rapid trend is the result of many complex socio-economic and political factors, and poses unprecedented challenges to the functioning of cities and the quality of life for urban dwellers. The resources needed for accommodating new urban dwellers will be enormous. Can emerging information, communication and ubiquitous access technologies help us to achieve a sustainable global urban system in a ubiquitous technology space, mitigating the consumption of scarce resources?
