As more of us begin to understand our food system, more of us seek to have more input into how food is grown, how it is treated after being harvested and how it moves from one place along the food route to another. People have begun to understand how far food travels, and that they, as the consumer, have had no say in what is grown or how it is grown. Urban agriculture can change that and in doing so it can take a rightful place is the larger food system.
Urban agriculture has become a means to increase access to locally grown food and a way of reintroducing the public to the many aspects of food that we have lost as a culture. How food grows, what grows regionally and seasonally are all important lessons and make a better informed urban consumer. Urban farms can be the front line of the food system.
For some the term urban implies inner city, like where Greens grow is. For others, urban has come to mean areas that are on the perimeter of cities (what some refer to as peri-urban). There is no single characterisation of size or placement; some are on rooftops, on landfills, brown fields, or areas where housing or industry may have been demolished. Some cities are giving up part of their park systems to allow urban farmers to plant their seeds. Every urban farm is different just as every rural farm is different.
Zoning plays a big role in urban agriculture. It can dictate what kind of growing may be allowed, whether animals, retail sales, and even education can be part of the operation. Many cities have multiple restrictions on raising animals with the result that most urban farms don’t keep animals for production purposes. Farming, big or small, is almost always a regulated activity. The production and selling of a food is potentially rife with safety and liability issues, as well as commerce, zoning and cultural issues.
Producing food for people to eat is a big responsibility and not to be entered into without a great deal of thought and planning.
Some urban farms are built exclusively for education, training or re-entry programs. Many are built to improve food access in a specific community or to continue traditional culinary cultures. Some are built as for profit concerns, recognising that the savings on food transportation can make urban farming financially viable as well as more environmentally responsible. For others food justice is the reason to develop urban farms in their communities, which means improving the access to fresh food for economically disadvantaged communities.
