Getting Cities Right

WASHINGTON, DC – The developing world is experiencing rapid urbanization, with the number of city dwellers set to reach four billion in 2030 – double its 2000 level. But unplanned and uncoordinated urban development is risky, threatening to replace migrants’ hopes for a better life with unsanitary living conditions, joblessness, and high exposure to natural disasters.

In many respects, urbanization is rational. After all, cities are the hubs of prosperity, where more than 80% of global economic activity is concentrated. And their density facilitates the delivery of public services, including education, health care, and basic services. Indeed, it costs $0.70-0.80 per cubic meter to provide piped water in urban areas, compared to $2 in sparsely populated areas.
