Can Urban Farms Save Cities in Decline?

We are finishing our film, Urban Roots, about the urban farming revolution in Detroit, and we are discussing the role that small, individually-owned urban farms have in "saving a city." We've run into some opinions that say that the thought that urban farms could save a city is somewhat naive, that, in fact what is needed are large-scale efforts to turn a city around.  "Scale" is needed, and "big profits."  The problem with this thinking I think is that it is stuck in the same mindset as the thinking that created the problem in the first place.  And the problem of saving a city is found in diagnosing the problem correctly. 

The problem of cities like Detroit is that the effort to preserve and grow big entities like corporations requires actions like what we witnessed - moving manufacturing overseas because labor was cheaper, cutting costs where-ever possible to bolster the bottom line and profits. Cutting costs and making profits, growing companies fast and big are what is heralded to be the goal and these things are rewarded by the stock market and by our culture in general.  Now, we are not against profits, but what is not helpful is to run a company, city or country with the bottom line/profits only in mind.  What is left out is the human element, the vitality of a company and a city and a country is the well-being of the people, the humans that live and work in it.  The mindset of our companies and country has so shifted to devalue the human element and value profit and size that we have run the very thing that makes the whole thing work - people - away. Look at Detroit, half the population has left, neighborhoods are empty, weeds grow in the playgrounds, schools have collapsed.  The mindset has killed off the community, has driven the people away. 

Now, out of this situation the remaining people have a choice and some of them have said they want to empower themselves by growing their own food and in some cases selling it to others. These farms are an acre or under, not thousands of acres.  How they benefit the city is that the empower a community, they give people ownership in their lives and each other, it gives them an income stream that cannot be taken away.  Some say scale is needed, but that brings in the same old mindset, put thousands of acres under cultivation under one group and the individual is yet again at the mercy of decisions beyond their control. And if the scale is too large, then yet again, the only way to sustain the size will be to minimize the human element and increase through non-human efficiencies like chemicals, and low wages.  How can small farms save a city?  They can do it one neighborhood at a time, slowly and hopefully with the help of city regulators who so often seek a quick fix and so often end up right where they started or oftentimes they end of worse off. Small farms bring in a new mindset, one of cooperation, barter, community, well-being, slowness but happiness perhaps.  It remains to be seen, we will be watching and we are open to the discussion!
