I recently came across an article on Gizmag.com about AeroFarms urban vertical aeroponic systems. I found the article to be an interesting and exciting description of yet another way for humans to grow food in environments where food production has been traditionally difficult or impossible.
What caught my attention more than the article, though, were the comments. The first comment was by someone blasting the technology because the commenter assumed the technology would not help make food production cheaper and more accessible to non-food producers.
Frankly, as someone who has recently entered the food production business, one of the conclusions I reached at the very beginning is that the idea that food production should be cheaper and more accessible to non-food producers is part of the reason why food continues to get more expensive, more inaccessible, and more scarce.
Not even 50 years ago, most people were involved either directly or indirectly in food production. In the United States, a majority of the population still lived in places considered rural and either worked on farms or at businesses that supported farms. Then came along the modernist idea that said we had too many farmers who did not produce enough cheap food, and the government and scientists engaged in an aggressive campaign to transform agriculture into what their modernized thinking believed it should be.
The result was that the number of people who list their occupation as “farmer” has dropped to less than 2 percent of the population. Meanwhile, most agricultural production in the United States has degenerated to just five major food sources: corn, soybeans, beef, chicken, and milk (yes, there is also pork, but it is not nearly as big as the top five). Further, most of the “food” sold in most grocery stores no longer comes from a farm but from a factory where the constituent components are processed, rendered, and reconstituted into things that look and smell like food but are more like a chemistry experiment gone awry.
And this method of food production has come with a hefty price tag that the world is only just starting to pay. Massive use of chemical fertilizers and killing agents have poisoned the ground, water, and air. There are places that are simply dead because of farm runoff. New, potent super weeds and bugs have come into existence as a result of forced selective breeding from the use of chemicals and medicines in food production. In some places, the obsessive focus on scientific food production (the NPK model) has resulted in farms that have “farmed out” due to the unavailability of the thousands of trace nutrients and soil components plants actually need to be healthy. Compact feeding operations create environmental damage on par with major chemical spills.
All of these problems factor back into the “cheap and accessible” model. Because people still demand inexpensive food they did not grow, modern agriculture must respond with more chemicals, more damaging cultivation methods, more concentrated food production systems, all of which compound the problems even more.
Unless everyone considers another way. AeroFarms, and the thousands of companies like it, are attempting to do something that the modern farming mythology cannot do: return mankind to a society centered around feeding itself–the theme of all of human history–without demanding that modern people give up their urbanized lives to return to rustic farm settings.
Of course, at first such technologies will be expensive and hard to come by, but over time, the best technologies will take hold, become more prevalent, and become less expensive. Further, the locally or self-produced model circumvents the “cheap and accessible” model and adds the benefit of increased local and individual independence from the vagaries of the worldwide economy and commodity markets.
So, if people really want cheap and accessible food, the best way to ensure that goal is for them to grow it themselves or to support those growing it specifically for them. Everyone can have enough food if enough people are growing it, but all of us have to start supporting that idea first.
