In the traditional sense, farming has always involved purchasing or leasing land to plow, plant, fertilize and harvest. As world population and land prices grow however, urban boundaries continue to expand, pushing farms and ranches farther away from the center of growing cities.
At the same time, many consumers are more aware of where their food is produced, preferring to purchase food grown locally in their communities. This trend pulls agriculture back into the heart of the city, with many agriculture enthusiasts stepping up to support the demand.
