Along with freedom and progress, efficiency rounds out the triad of the most treasured ideals of our country. We like things to be "efficient," without really knowing what it means. Americans tend to use the term efficiency as a code word for getting things done cheaply and conveniently. Take agriculture, for example. It certainly is an achievement to churn out food at prices that are far less than historical averages (by percentage of family budget spent on food). That frees up a lot of money for people to spend on other things - clothes, travel, books, furniture, whatever your desire might be.
But what makes efficiency? Is it clever management? The productivity of human resources? Economies of scale? Centralization? Better information and computer systems? The competition of markets?
Business people give credit to these innovations, and all of these attributes may contribute incrementally to the cheapness of our food, but these are just icing on the cake. The real underpinning of what we think of as efficiency is cheap energy - especially cheap oil.
Farms here in America have been consolidating for more than 50 years. The average size of a "farm" is now 459 acres. They are managed with the aid of GPS systems, barns of tractors, and miles of irrigation systems. The farms of today have replaced people, armed with knowledge of local conditions and crop varieties and supported by rainfall and rich topsoil, with machines fueled by gasoline and regular applications of chemicals created from fossil fuels.
Efficiency, in other words, means replacing energy from humans and animals and plants with the incredibly cheap, concentrated energy found in oil. It does not mean less waste (at least when measured in BTUs). Americans pride ourselves on our innovations, but we did not in fact create better, less wasteful farming systems - we just found ways to pour as much of this cheap energy into our farms as possible, without considering how long the resource would remain cheap.
Small farms are actually more productive and efficient than large farms. They produce more per acre. However, while fuel is inexpensive, small farms cannot achieve the massive economies of scale enabled by the replacement of people with gigantic tractors and chemicals. Since a gallon of oil can replace the energy of hundreds of hours of human labor, at a fraction of the cost, it makes a whole lot of economic sense to use it in place of people.
Replacing man (and horse) with machines may seem efficient, but it is not the efficiency of nature, which uses every particle of matter and energy, including any waste produced. It is the economic efficiency of man, which inevitably generates pollution and destruction because the costs are not borne by the user, but by nature and by the community at large. What we call efficiency is simply the conversion of a fossil fuel inheritance millions of years in the making into cheap fuel and food for a few generations.
What we call efficiency is actually the height of inefficiency. The foundation of modern agriculture is mostly just the addition of more energy to the system, and any fool can do that. Our current food systems are only made possible by incredible wastefulness, ruination of natural systems, and unbridled use of our inheritance of fossil fuels. These are the costs that our economic accounting does not take into account.
How efficient will it be to manage a 1,000 acre farm when production of oil begins to decline? How efficient will it be to ship lettuce 1,500 miles when gas costs $6 a gallon? How efficient will it be to use 20 calories of fossil fuels to create one calorie of food? What will we be left with when the Age of Oil begins to wane? Eroded topsoil, depleted aquifers, and the loss of the valuable farming knowledge of entire generations of Americans.
Here in Oklahoma, we are lucky to have small farmers still holding on to their farms and activists dedicated to reviving our local, sustainable and organic foodsheds. We have the Oklahoma Food Co-operative, an Extension Service supportive of sustainable agriculture, Community Supported Agriculture shares, and several local farmer's markets. Many of the people living here have memories of farms, of growing gardens and raising animals, and many continue to grow fruits and vegetables regardless of whether they live in the country or city. Here we are not far away from our food.
As the price of fuel rises, the myth of efficiency will be exposed. We can choose to recognize that our ideal was an illusion, and rebuild our local food systems and economies now, or we can choose to be a deer in the headlights as the price of food rockets along with the price of fuel. We can use real design innovations, like permaculture and integrated pest management, which rely on careful observation and knowledge of the ecology, instead of the application of chemicals. We don't know when high gas prices will return, but oil has already demonstrated an ample capacity for volatility. Let's prepare now, so that we won't have to pay later.
