The Truth-Small farms produce more agricultural output per unit area than large farms. Moreover, larger, less diverse farms require far more mechanical and chemical inputs. These ever increasing inputs are devastating to the environment and make these farms far less efficient than smaller, more sustainable farms.

Proponents of industrial agriculture claim that "bigger is better" when it comes to food production. They argue that the larger the farm, the more efficient it is. They admit that these huge corporate farms mean the loss of family farms and rural communities, but they maintain that this is simply the inevitable cost of efficient food production. And agribusinnes advocates don't just promote big farms; they also push big technology. They typically ridicule small-scale farm technology as grossly inefficient, while heralding intensive use of chemicals, massive machinery, computerization, and genetic engineering - whose affordability and implementation are only feasible on large farms. The marriage of huge farms with "mega-technology" is sold to the public as the basic requirement for efficient food production. Argue against size and technolgy -the two stapes of modern agriculture - and, they insist, you're undermining production efficiency and endangering the world's food supply.


While the "bigger is better" myth is generally accepted, it is a fallacy. Numerous reports have found that smaller farms are actually more efficient than larger "industrial" farms. These studies demonstrate that when farms get larger, the costs of production per unit often increase, because larger acreage requires more expensive machinery and more chemicals to protect crops. In particular, a 1989 study by the U.S. National Research Council assessed the effiency of large industrial food production systems compared with alternative methods. The conclusion was exactly contrary to the "bigger is better" myth: "Well-managed alternative farming systems nearly always use less synthetic chemical pesticides, fertilizers, and antibiotics per unit of production than conventional farms. Reduced use of these inputs lowers production costs and lessens agriculture's potential for adverse environmental and health effects without decreasing - and in some cases increasing - per acre crop yields and the productivity of livestock mangement systems."

Moreover, the large monocultures used in industrial farming undermine the genetic integrity of crops, making them more susceptible to diseases and pests. A majority of our food biodiversity has already been lost. This genetic weakening of our crops makes future food productivity using the industrial model far less predictable and undermines any future effiency claims of modern agriculture. Moreover, as these crops become ever more susceptible to pests, they require ever greater use of pesticides to produce equal amounts of food - a classic case of the law of diminishing returns. This increasing use of chemicals and fertilizers in our food production results in serious health and environmental impacts.

With all this evidence against it, how does the "bigger is better" myth survive? In part, it survives because of a deeply flawed method of measuring farm "productivity" which has falsely boosed the efficiency claims of industrial agriculture while discounting the productivity advantages of small-scale agriculture.


Agribusiness and economists alike tend to use "yield" measurements when calculating the productivity of farms. Yield can be defined as the production per unit of a single crop. For example, a corn farm will be judged by how many metric tons of corn are produced per acre. More often than not, the highest yield of a single crop like corn can be best achieved by planting it alone on an industrial scale in the fields of corporate farms. These large "monocultures" have become endemic to modern agriculture for the simple reason that they are the easiest to manage with heavy machinery and intensive chemical use. It is the single-crop yields of these farms that are used as the basis for the "bigger is better" myth, and it is true that the highest yield of a single crop is often achieved through industrial monocultures.

Smaller farms rarely can compete with this "monoculture" single-crop yield. They tend to plant crop mixtures, a method known as "intercropping." Additionally, where single-crop monocultures have empty "weed" spaces, small farms uses these spaces for crop planting. They are also more likely to rotate or combine crops and livestock, awith the resulting manure performing the important function of replenishing soil fertility. These small-scale integrated farms produce far more per unit area than large farms. Though the yield per unit area of one crop - corn, for example - may be lower, the total output per unit area for small farms, often composed of more than a dozen crops and numerous animal products, is virtually always higher than that of larger farms.

Clearly, if we are to compare accurately the productivity of small and large farms, we should use total agricultural output, balanced against total farm inputs and "externalities," rather than single-crop yield as our measurement principle. Total output is defined as the sum of everything a small farmer produces -various grains, fruits, vegetables, fodder, and animal products - and is the real benchmark of efficiency in farming. Moreover, productivity measurements should also take into account total input costs, including large-machinery and chemical use, which often are left out of the equation in the yield efficiency claims. Perhaps most important, however, is the inclusion of the cost of externalities such as environmental and human health impacts for which industrial scale monocultured farms allow society to pay. Continuing to measure farm efficiency through single-crop "yield" in agricultural economics represents an unacceptable bias against diversification and reflects the bizarre conviction that producing our food crop on a large scale is more important than producing many crops (and higher productivity) on a small scale.

Once the flawed yield measurement system is discarded, the "bigger is better" myth is shattered. As summarized by the food policy expert Peter Rosset, "Surveying the data, we indeed find that small farms almost always produce far more agricultural output per unit area than larger farms. This is now widely recognized by agricultural economists across the political spectrum, as the 'inverse relationship between farm size and output.'" He notes that even the World Bank now advocates redistributing land to small farmers in the third world as a step toward increasing overall agricultural productivity. (WOW It's not very often that I'm in agreeance with the World Bank! )

Government studies underscore this "inverse relationship." According to a 1992 U.S. Agricultural Census report, relatively smaller farm sizes are 2 to 10 times more productive (in dollar output per acre) than large farms (6,000 acres or more), and extremely small farms (4 acres or less) can be over a hundred times as productive.

In a last-gasp effort to save their efficiency myth, agribusiness will claim that at least larger farms are able to make more efficient use of farm labor and modern technology than are smaller farms. Even this claim cannot be maintained. There is virtual consensus that larger farms do not make as good use of even these production factors because of management and labor problems inherent inlarge operations. Mid-sized and many smaller farms come far closer to peak efficiency when these factors are calculated.

It is generally agreed that an efficient farming system would be immensely beneficial for society and our environment. It would use the fewest resources for the maximum sustainable food productivity. Heavily influenced by the "bigger is better" myth, we have converted to industrial agriculture in the hopes of creating a more efficient system. We have allowed transnational corporations to run a food system that eliminates livelihoods, destroys communities, poisons the earth, undermines biodiversity, and doesn't even feel the people. All in the name of efficincy. It is indisputalble that this highly touted modern system of food production is actually less efficient, less productive than small-scale alternative farming. It is time to reembrace the virtues of small farming, with its intimate knowledge and techniques like intercropping, cover cropping, and seasonal rotations; its saving of seeds to preserve genetic diversity; and its better integration of farms with forest, woody shrubs, and wild plant and animal species. In other words, it's time to get efficient.
