The 2010 US Census data released this week revealed that Detroit, among other cities, lost more residents than initially thought. This week, SGA asks: What can cities like Detroit do to rebuild their local economy?

The New York Times’ Room for Debate debates this issue in depth, with eight experts weighing in on revitalization opportunities presented by increasingly vacant cities across America. Among the points they raise:

• What if the government used a fraction of the billions it spends to subsidize home-building on ‘unbuilding’ projects instead?
• The record of top-down schemes to revive cities by remaking neighborhoods is littered with disastrous unintended consequences.
• The key to restoring a shrinking city’s health is to cut costs of doing business and ensure access to quality education.
• Build vegetable gardens and parks, but also consider tax incentives.
• We need to get over our tendency to throw out damaged goods; instead we need to retrofit them.

Which of the authors do you agree with? Disagree with? What role can abandoned property revitalization play in reviving a city?
