The challenge of urban growth and sustainable development for Asian cities in the 21st century

The challenges of urban growth for mega-cities in Asia, now and over the next few decades, are examined with particular reference to the ability or inability of those in charge of cities, elected officials and administrators, to provide for the legitimate demands of citizens. Issues such as population growth, industrialization, urbanization, financing, employment, health care, social services, public safety, transportation, water supply, waste disposal, and cultural and recreational facilities are included. While sustainable development of cities is advocated strongly by environmentalists and administrators, the past history of urban growth is quite often the opposite. Why?

Finally, the important contributions made by environmental scientists and engineers towards more sustainable development are placed in context with the reality of urban growth
