This new report proposes how urbanization, urban planning, and policy need to change in the years ahead. Its message is clear -- the current model of urbanization is unsustainable, and cities all over the world are unprepared for the challenges ahead.

City leaders across the United States need to pay close to attention to this report. It is not a document just for the rest of the world. The messages are relevant to everyone.

Many of the best ideas for solving urban problems are being developed abroad. To succeed in coping with the pressures of urban growth, we must pay attention to innovations in other countries.

Investments in infrastructure are not optional. World-class roads, transit, schools, and utilities are key to economic competitiveness as well as quality of life. Many of our competitors get this; we have to as well.

Our urban growth and environmental challenges frequently have global dimensions. To respond to pollution, sea level rise, and security in an age of terrorism and to increase jobs and trade, we have to work together with others around the world. 

When done correctly, urbanization will build economic value, protect the environment, and foster an improved quality of life for us all.
