A growing dream of urban farming: Financier Hantz wants to plant $30M into vacant lots

Being from Michigan originally, I'm interested in the plight of Detroit. Click title for link to article about establishing large scale farming in a formerly urban area - way beyond chickens in the backyard. Such is the state of decay in the city of Detroit that eventually 5,000 acres could be included. Land prices are running about $3,000 an acre. The first stage will consist of 77 acres - property tax issues remain that currently prevent this use from being feasible.

Not recommending this here, but it is an example of the devolution of former urban land into agriculture. We may some day have suburban development that surrounds agricultural lands - what were once major urban centers of the 19th and 20th Centuries.
