Questions We Aren't Asking in Agriculture: Beginning the Journey Toward a New Vision

I am not a scientist or a technician. I am a farmer and a philosopher. I am aware that in our industrial culture that makes me intellectually suspect and a bit of an oddball as a lecturer at a meeting of an agriculture honor society.
In my defense I want to note that philosophers and farmers have played an important role in human civilization. Farmers have helped us to stay alive, and philosophers have helped us to learn how to live.
Perhaps that is belaboring the obvious. But in our "technopoly" culture we have been led to believe that agriculture need ask only one question: "How much does it produce?" Indeed, Paul Thompson at Purdue University argues that farmers in our culture have been taught to subscribe to only one ethic---produce as much as possible regardless of the cost. (Thompson, 1995)
And we believe that technology is all we need to achieve our production goals.
And increasingly technological innovation to increase productivity has become the sole research goal of both public and private research institutions.
Farmers, consequently, have been driven to become primarily appliers of technology, and philosophers have been relegated to esoteric functions with little to contribute to the public good. In fact anyone who appears to have little to contribute to our global industrial economy---the growth of which is increasingly the single goal of our society---incurs the risk of being considered a vestige of the past (or worse, a "Luddite"). Accordingly, we don't expect much in the way of meaningful intellectual leadership from either our farmers or our philosophers.
Philosophers, however, have the annoying habit of asking questions that the prevailing culture doesn't like to ask. It's what got Socrates into trouble. Having said that, I want to be clear. I'm not offering to drink hemlock tonight and I trust I won't be accused of corrupting the nation's youth, which you will recall was Socrates' crime. But I think it is time to ask some questions of agriculture that aren't being widely discussed today.
I can think of no better place, than this place---here among agriculture's honor students, here in Iowa---to begin asking these questions. I assume you are our brightest and best, otherwise you would not have been inducted into the coveted Gamma Sigma Delta. And Iowa is the heartland of American agriculture. The questions we ask of agriculture here may begin to shape the questions we ask nationally.
I can also think of no one who is more obliged to begin asking these questions than the Director of the Leopold Center. The Iowa State Legislature created the Leopold Center to be an agent for change---to be instrumental in the development of a resilient agriculture for the state of Iowa that is consistent with the philosophy of Aldo Leopold.
Many of the questions I will be asking us to consider tonight are, in fact, similar in character to some that Leopold asked himself. Early in his life Leopold was convinced, as most of us are, that science and technology could solve most of our problems---including those facing conservation. Later he warned that we needed to be wary of "salvation by machine," (1933) and that without a compelling land ethic that was ecologically grounded, we wouldn't make much progress, long term, toward our ecological, social or our economic goals. (1949)
So I'd like to challenge you tonight to begin thinking with me and my colleagues at the Leopold Center about three questions that confront agriculture as we enter the 21st century.
I. What is Our Vision for Agriculture?
This continent has, in fact, enjoyed four visions for agriculture during its history. The first vision was one held by native Americans. Their vision for agriculture was to feed the village---everyone in the village---and to do so in a manner that disturbed nature as little as possible. So during the 15,000 years that native Americans lived on this continent before Europeans arrived, they developed the three sisters agriculture (corn, beans and squash) which they planted as companions in small, almost unnoticeable crevices of the ecological landscapes in which they lived.
The second vision for agriculture was brought to this continent by the Puritans in the early 1600s. They were driven by a vision of "taming the wilderness and building the kingdom of God." And agriculture was a key component of that vision. Their vision of the kingdom of God included cleared forests, plowed prairies and nice neat rows of corn. It was an integral part of the social order they envisioned for their "new" life on this "new" land.
A third vision for agriculture dominated this continent in the 18th and 19th centuries. That vision saw agriculture as a civilizing force. Thomas Jefferson was its leading voice. Jefferson envisioned a democratic republic consisting of thousands of small farm landholders, none beholden to political patronage or economic dependency, and therefore free to speak their minds and vote their conscience.
In the 20th century, our vision for agriculture became part and parcel of our industrial dream. We envisioned an agriculture that could produce all of our food and fiber (plus that of much of the rest of the world) with a dramatically reduced labor force, "freeing" citizens to engage in industrial and professional pursuits that could dramatically improve our common quality of life.
Now it is important to recognize that in each of these visions agriculture is seen as a public good---not simply a means of producing food and fiber. Agriculture was seen as the vehicle for:
Each of these visions was compelling. They invited society to support agriculture because agriculture was part and parcel of a mission that served a greater good.
In a forum sponsored by the Leopold Center several weeks ago, Karl Stauber, president of the Northwest Area Foundation, suggested that one of the dilemmas facing us today is that we have no compelling vision for agriculture as we enter the 21st century.
Today agriculture is perceived more as a public problem than a public good. If agriculture comes to mind at all for modern suburbanites, it is usually in connection with a problem that agriculture is perceived to have created. If agriculture is not perceived as the origin of our polluted groundwater, it is the culprit that is devastating the landscape with eroded soils, destroyed rain forests, intolerable odors, or end-of-stream dead zones. If it is not perceived as a leviathan force that prevents consumers from exercising freedom of choice in the marketplace, or denying farmers access to free markets, it is seen as a threat to public health, implicated in everything from mad cow disease, to E. coli, to cancer, to endocrine disruption.
So one of the challenges we face today is to develop a vision for agriculture that will enable citizens to perceive it, once again, as a public good. That vision must be grounded in observable results that meet the public's expectations. Those expectations now, as in the past, go beyond providing adequate quantities of safe, nutritious, good-tasting food.
Today the public expects, at least, that agriculture produce healthy ecosystems, human communities that enable families and farm workers to live a decent life, and domestic animal environments that show respect for normal animal behavior. Any vision for agriculture that fails to meet these "on the ground" objectives is not likely to be sufficiently compelling to enlist the support of urban and suburban citizens. Simplistic cliches like "feeding the world" won't do.
So I invite each of you to join us at the Leopold Center to meet this new challenge, to begin the process of developing this new vision for agriculture.
This is not an easy task, nor one that we will complete in the next six months. But at least we can begin by asking the question---what kind of vision do we want for 21st century agriculture?
II. What are the New Problems Facing Agriculture in a "Full" World?
The fact that agriculture is vision-less and perceived as a public problem is an opportunity rather than a barrier. Since the problems of agriculture are widely recognized, there will be broad public support to develop a new vision that addresses those problems.
Agriculture is already part of some of the most important and preeminent social agendas of the world. Two years ago Jane Lubchenco, then president of one of the most prestigious scientific professional associations in the world, the American Association of the Advancement of Science, challenged the entire scientific community to rethink its social contract based on the fact that we now, for the first time, live in a human-dominated planet---or what Herman Daly likes to call a "full world." (Daley, 1996)
Living in a full world means we no longer have unlimited natural resources to satisfy all our desires or unlimited sinks for the wastes generated by our activities. We no longer live in a world in which the impact of the human species is easily absorbed by the ecosystems in which we live. The size of the "ecological footprint" (Rees, 1999) that we leave today is now so large that we can no longer ignore the impact that our agricultural activities have on our local ecosystems.
Agricultural activities are central to our ecological footprint. When Jane Lubchenco issued her challenge to the scientific community to craft a new social contract---asking them to "devote their energies and talents to the most pressing problems of the day ..."--- easily half of the problems she outlined are directly related to agriculture. Not least among the problems she identified is the fact that "more atmospheric nitrogen is fixed by humanity than by all natural terrestrial sources combined." (Lubchenco, 1998)
In other words, scientists both inside and outside agriculture now increasingly recognize a mounting set of problems created at least in part by agriculture. We simply have to deal with them if we are going to survive very far into the next century with any kind of quality of life.
Those problems include, but are not limited to:
How do we produce the additional food to feed the additional mouths without doing additional harm to an already damaged planet? How do we redesign the food system so that the hungry will be entitled to the food we produce? We currently have over 800 million malnourished people on the planet and insufficient production is clearly not the problem. How do we restore the health and diversity to our ecological communities to mitigate the additional disease that will clearly come with several additional billion humans in a world that is already too full? These and many other problems make it clear that an expanding human population requires much more than simply producing more foodstuff.
Now, many in our society would argue that while the environmental problems noted above are indeed critical, the declining farm numbers are not. As one federal government official put it when I asked her about the declining farm population some years ago, "If two or three farmers can produce all the food and fiber we need to meet our domestic and export requirements, who cares? In fact, if robots can do it who cares?"
Well, the brutal fact is that if all we expect from agriculture is that it produce as much as possible regardless of the cost, then she is right. Indeed, if all we ask of agriculture is that it produce sufficient quantities of food and fiber as efficiently as possible on a global scale, then Steven Blank, professor of Agriculture and Resource Economics at UC Davis, was correct when he suggested recently that the United States should get out of the farming business altogether because it can't compete with low-cost producers in other parts of the world. We should then, as Blank argued, put our national resources to work on higher value producing activities and leave the production of raw materials to others.
But farms are more than food factories. Farms aren't just an economic bubble floating in space with unlimited resources coming in, unlimited capacity to produce within the bubble, and unlimited space outside the bubble for waste going out. The 20th century vision for agriculture, producing as much as possible as efficiently as possible and externalizing all of the costs, may have worked in an empty world. It doesn't work in a full world.
Farms are ultimately not factories, they are biological organisms. As such they are an integral part of the ecosystems in which they exist. As biological organisms they function in a context of biological restraints that we cannot ignore for very long.
Craig Holdredge (1996), a young biologist in upstate New York, reminds us, with a simple illustration, why that is true. When we treat a cow like a milk factory whose milk production can be increased by tweaking some isolated part of the cow's physiology, we lose sight of the fact that for every additional quart of milk that the cow is forced to produce, an extra 300 to 500 quarts of blood must flow through the udder of the cow. To pretend that increasing the milk production of the cow can be done without having any effect on the cow, or the environment in which the cow exists, or the community of which the cow is a part, is---if nothing else---bad science.
The reason that good farmers are important to the future of agriculture in a full world, is that ecosystems cannot be managed like factories. As Niles Eldredge, paleontologist with the Museum of Natural History, reminds us, there is no such thing as a global ecosystem---there are only local ecosystems, and the health of our planet depends on the health of the combined local ecosystems. (Eldredge, 1995)
So we cannot manage the restoration of the health of our global home on a mass scale through centralized, global planning. Each local ecosystem is unique. The free ecosystem services that feed each ecosystem, and that ultimately make agriculture possible in it, are unique to the location in which they exist. So the only way we can manage farms within local ecosystems in an ecologically sound manner, is if we have farmers living in those ecosystems long enough and intimately enough to learn how to farm in them in an ecologically amenable manner.
The reason we need farm families living in local ecosystems with the knowledge of those local ecologies passed from one generation to the next is that it is the most efficient way (and perhaps the only way) for agriculture to function in an ecologically sound fashion. Preserving the family farm has nothing to do with nostalgia, it has everything to do with maintaining a resilient agriculture in a full world.
In this regard, agriculture is not an isolated enterprise in trouble. It is not just agriculture that must learn how to fit into a full world, it is all of our human enterprises. The task before us is to reshape the way we relate to the ecosystems in which we live so as to permit renewal and restoration of both the ecosystems and the institutions we have created in them---including agriculture. And that requires a fundamental paradigm shift in our thinking.
Lance Gunderson and his colleagues have characterized this indispensable shift as abandoning our illusion of control management and replacing it with adaptive management. (Gunderson, et al. 1995)
That provides us with one of several clues that may help us chart our way toward a new agriculture.
