There was a time not so long ago when famine was an expected, if not accepted, part of life. Until the 19th century — whether in China, France, India or Britain — food came almost entirely from local sources and harvests were variable. In good years, there was plenty—enough for seasonal feasts and for storage in anticipation of winter and hard times to come; in bad years, starvation cut down the poorest and the weakest—the very young, the old, and the sickly. Sometimes bad years followed one upon another, reducing the size of the population by several percent. This was the normal condition of life in pre-industrial societies, and it persisted for thousands of years.
Today, in America, such a state of affairs is hard to imagine. Food is so cheap and plentiful that obesity is a far more widespread concern than hunger. The average mega-supermarket stocks an impressive array of exotic foods from across the globe, and even staples are typically trucked from hundreds of miles away. Many people in America did go hungry during the Great Depression, but those were times that only the elderly can recall. In the current regime, the desperately poor may experience chronic malnutrition and may miss meals, but for most the dilemma is finding time in the day’s hectic schedule to go to the grocery store or to cook. As a result, fast-food restaurants proliferate: the fare may not be particularly nutritious, but even an hour’s earnings at minimum wage will buy a meal or two. The average American family spent 20 percent of its income on food in 1950; today the figure is 10 percent.
This is an extraordinary situation; but because it is the only one that most Americans alive today have ever experienced, we tend to assume that it will continue indefinitely. However there are reasons to think that our current anomalous abundance of inexpensive food may be only temporary; if so, present and future generations may become acquainted with that old, formerly familiar but unwelcome houseguest—famine.
The third worrisome trend is an increasing scarcity of fresh water. Sixty percent of water used nationally goes toward agriculture. California’s Central Valley, which produces the substantial bulk of the nation’s fruits, nuts, and vegetables, receives virtually no rainfall during summer months and relies overwhelmingly on irrigation. But the snowpack on the Sierras, which provides much of that irrigation water, is declining, and the aquifer that supplies much of the rest is being drawn down at many times its recharge rate. If these trends continue, the Central Valley may be incapable of producing food in any substantial quantities within two or three decades. Other parts of the country are similarly overspending their water budgets, and very little is being done to deal with this looming catastrophe.
We have been trained to admire the benefits of intensification and industrialization. But, as I’ve already indicated, we have paid an enormous price for these benefits—a price that includes alienation from nature, loss of community and tradition, and the acceptance of the anonymity and loss of autonomy implied by mass society. In essence, this tradeoff has its origins in the beginnings of urbanization and agriculture.
Could we actually regain much of what we have lost? Yes, perhaps by going back, at least in large part, to horticulture. Recall that the shift from horticulture to agriculture was, as best we can tell, a fateful turning point in cultural history. It represented the beginning of full-time division of labor, hierarchy, and patriarchy.
Biointensive farming and Permaculture are primarily horticultural rather than agricultural systems. These new, intelligent forms of horticulture could, then, offer an alternative to a new feudalism with a new peasantry. In addition, they emphasize biodiversity, averting many of the environmental impacts of field cropping. They use various strategies to make hand labor as efficient as possible, minimizing toil and drudgery. And they typically slash water requirements for crops grown in arid regions.
We have gotten used to a situation where most farmers rely on non-farm income. As of 2002 only a bit less than 60 percent of farm operators reported that their primary work is on the farm. Only 9 percent of primary operators on farms with one operator, and 10 percent on farms with multiple operators, report all of their income as coming from the farm.
The bad side of this is that it means it’s hard to make a living farming these days. The good side is that we don’t have to think of farming as an exclusive occupation. As people return to small communities and to farming, they could bring with them other interests. Rather than a new peasantry that spends all of its time in drudgery, we could look forward to a new population of producers who maintain interests in the arts and sciences, in history, philosophy, spirituality, and psychology—in short, the whole range of pursuits that make modern urban life interesting and worthwhile.
Moreover, the re-ruralization program I am describing could be a springboard for the rebirth of democracy in this nation. I do not have to tell this audience how, over the past few years, democracy in America has become little more than a slogan. In fact this erosion of our democratic traditions has been going on for some time. As Kirkpatrick Sale showed in his wonderful book Human Scale, as communities grow in size, individuals’ ability to influence public affairs tends to shrink. Sociological research now shows that people who have the ability to influence policy in their communities show a much higher sense of satisfaction with life in general. In short, the re-ruralization of America could represent the fulfillment of Thomas Jefferson’s vision of an agrarian democracy—but without the slaves.
If we do this well, it could mean the revitalization not only of democracy, but of the family and of authentic, place-based culture. It could also serve as the basis for a new, genuine conservatism to replace the ersatz conservatism of the current ruling political elites.
What I am proposing is nothing less than a new alliance among environmental organizations, farmers, gardeners, organizations promoting economic justice, the anti-globalization movement, universities and colleges, local businesses, churches, and other social organizations. Moreover, the efforts of this alliance would have to be coordinated at the national, state, and local level. This is clearly a tall order. However, we are not talking about merely a good idea. This is a survival strategy.
It may seem that I am describing and advocating a reversion to the world of 1800, or even that of 8,000 BC. This is not really the case. We will of course need to relearn much of what our ancestors knew. But we have discovered a great deal about biology, geology, hydrology, and other relevant subjects in recent decades, and we should be applying that knowledge—as Holmgren, Mollison, Jeavons, and others have done—to the project of producing food for ourselves.
Cultural anthropology teaches us that the way people get their food is the most reliable determinant of virtually all other social characteristics. Thus, as we build a different food system we will inevitably be building a new kind of culture, certainly very different from industrial urbanism but probably also from what preceded it. As always before in human history, we will make it up as we go along, in response to necessity and opportunity.
Perhaps these great changes won’t take place until the need is obvious and irresistibly pressing. Maybe gasoline needs to get to $10 a gallon. Perhaps unemployment will have to rise to ten or twenty or forty percent, with families begging for food in the streets, before embattled policy makers begin to reconsider their commitment to industrial agriculture.
But even in that case, as in Cuba, all may depend upon having another option already articulated. Without that, we will be left to the worst possible outcome.
Rather than consigning ourselves to that fate, let us accept the current challenge—the next great energy transition—as an opportunity not to vainly try to preserve business as usual, the American Way of Life that, we are told, is not up for negotiation, but rather to re-imagine human culture from the ground up.
The Expansion Period (1600 to 1920): Increases in food production during these three centuries came simply from putting more land into production; technological change played only a minor role.
The Mechanization Period (1920 to 1970): In this half-century, technological advances issuing from cheap, abundant fossil-fuel energy resulted in a dramatic increase in productivity (output per worker hour). Meanwhile, farm machinery, pesticides, herbicides, irrigation, new hybrid crops, and synthetic fertilizers allowed for the doubling and tripling of crop production. Also during this time, U.S. Department of Agriculture policy began favoring larger farms (the average U.S. farm size grew from 100 acres in 1930 to almost 500 acres by 1990), and production for export.
The Saturation Period (1970-present): In recent decades, the application of still greater amounts of energy have produced smaller relative increases in crop yields; meanwhile an ever-growing amount of energy is being expended to maintain the functioning of the overall system. For example, about ten percent of the energy in agriculture is used just to offset the negative effects of soil erosion, while increasing amounts of pesticides must be sprayed each year as pests develop resistances. In short, strategies that had recently produced dramatic increases in productivity became subject to the law of diminishing returns.
While we were achieving miracles of productivity, agriculture’s impact on the natural world was also growing; indeed it is now the single greatest source of human damage to the global environment. That damage takes a number of forms: erosion and salinization of soils; deforestation (a strategy for bringing more land into cultivation); fertilizer runoff (which ultimately creates enormous “dead zones” around the mouths of many rivers); loss of biodiversity; fresh water scarcity; and agrochemical pollution of water and soil.
In short, we created unprecedented abundance while ignoring the long-term consequences of our actions. This is more than a little reminiscent of how some previous agricultural societies—the Greeks, Babylonians, and Romans—destroyed soil and habitat in their mania to feed growing urban populations, and collapsed as a result.
Fortunately, during the past century or two we have also developed the disciplines of archaeology and ecology, which teach us how and why those ancient societies failed, and how the diversity of the web of life sustains us. Thus, in principle, if we avail ourselves of this knowledge, we need not mindlessly repeat
