Mr. President, Time to Create the People’s Agriculture
[imgbelt img=three-sisters.jpeg]Native American wisdom says that decisions should be made with the next seven generations in mind. When it comes to agriculture and the production of food, we don’t look ahead at all.
Sustainable agriculture is more of a philosophy than a well-defined system or vision. Fred Kirschenmann points out that the basic concept “has focused our attention on how to make agriculture a little less bad—how to reduce soil erosion, how to mitigate the effects of toxic chemicals, how to improve our water quality, etc.”
Enough people have now subscribed to the sustainable philosophy that corporate agribusiness is catering products to this growing consumer group.
Unfortunately there are no legal standards governing sustainable food, which invites mischief and deceptive advertising.
Urban Skyscraper Farms
One vision put forth in a recent Scientific American article is an urban skyscraper, or vertical farm.
In many ways, the vertical farm may be more of a fantasy than a vision. It is industrial farming on a vertical rather than horizontal scale. This concept is attractive because wastes and plant nutrients can be recycled, and because it eliminates the cost of transporting food long distances.
But there are numerous economic and biological reasons why the high-rise idea may be nothing more than a pie-in-the-sky idea! The food skyscrapers would have to be extremely narrow, or have significant fewer floors, or integrated on the south side of office and residential buildings to get adequate sunlight to plants. Capital costs would be enormous.
Use of “cleansed city wastewater” is also problematic from a cost standpoint, due to all kinds of impurities and toxicants in municipal wastes, including drugs, growth hormones and heavy metals. Some plants uptake and concentrate heavy metals and impurities. Some heavy metals, such as mercury and lead, are toxic to humans. Costs of cleansing wastewater are high with known technology.
There is potential biological peril to relying on a food skyscraper for food, as many food crops are susceptible to air borne diseases. Such diseases could easily wipe out uniform crops depicted, or require use of pesticides inside an urban building that includes restaurants.
Greenhouse Fruit & Vegetable Production
Production of high value vegetable crops and some fruit crops in greenhouses and hoop houses is expanding rapidly in many parts of the world, particularly where extensive acreage of high quality land is not available. World acreage of covered vegetable production now exceeds a million acres, with over 300,000 acres in Europe. Over 900 acres of hydroponic (without soil) tomatoes are grown in the U.S.
Some of these covered production systems are nothing more that industrial farming on an intense, horizontal scale. Some covered systems may be sustainable. Most are located on the fringe of urban areas.
In many urban areas, changes in local land use restrictions and bans on certain farm animals are incompatible with urban gardening on a large scale.
A considerably less grandiose urban farm that integrates food production with restaurants is a “farmery” constructed from used, low cost shipping containers. This concept combines covered production with a retail outlet.
Organic Farming and Gardening
Organic farming gained traction as a movement in the 1970s with concern over man-made chemicals—fertilizers and pesticides—that are now at the core of industrial agriculture. Initially, organic farming was small scale. As small organic producers developed markets and the industry began to expand in the 1980s, corporate agribusiness moved in and now dominates the industry.
USDA standards for organic produce provide some assurance to consumers about production practices, unlike “natural foods” and food from “sustainable” farms. Lack of any standards for natural foods and sustainable practices often leads to deceptive advertising.
