What is Sustainable Agriculture?
Some terms defy definition. “Sustainable agriculture” has become one of them. In such a quickly changing world, can anything be sustainable? What do we want to sustain? How can we implement such a nebulous goal? Is it too late? With the contradictions and questions have come a hard look at our present food production system and thoughtful evaluations of its future. If nothing else, the term “sustainable agriculture” has provided “talking points,” a sense of direction, and an urgency, that has sparked much excitement and innovative thinking in the agricultural world.
The word “sustain,” from the Latin sustinere (sus-, from below and tenere, to hold), to keep in existence or maintain, implies long-term support or permanence. As it pertains to agriculture, sustainable describes farming systems that are “capable of maintaining their productivity and usefulness to society indefinitely. Such systems... must be resource-conserving, socially supportive, commercially competitive, and environmentally sound.” [John Ikerd, as quoted by Richard Duesterhaus in "Sustainability's Promise," Journal of Soil and Water Conservation(Jan.-Feb. 1990) 45(1): p.4. NAL Call # 56.8 J822]
Sustainable agriculture was addressed by Congress in the 1990 Farm Bill [Food, Agriculture, Conservation, and Trade Act of 1990 (FACTA), Public Law 101-624, Title XVI, Subtitle A, Section 1603 (Government Printing Office, Washington, DC, 1990) NAL Call # KF1692.A31 1990]. Under that law, “the term sustainable agriculture means an integrated system of plant and animal production practices having a site-specific application that will, over the long term:
• satisfy human food and fiber needs
• enhance environmental quality and the natural resource base upon which the agricultural economy depends
• make the most efficient use of nonrenewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls
• sustain the economic viability of farm operations
• enhance the quality of life for farmers and society as a whole.”
As more parties sign on to the sustainable agriculture effort, perceptions about what defines sustainability in agriculture have multiplied. AFSIC's publication, Sustainable Agriculture: Definitions and Terms, http://www.nal.usda.gov/afsic/pubs/terms/srb9902.shtml strives to illustrate the commonality and some of the controversy that defining such a goal entails, and it includes brief descriptions of the methodologies and practices currently associated with sustainable agriculture.
“In popular literature, sustainable agriculture generally is presented as a new phenomenon. Wes Jackson is credited with the first publication of the expression in his New Roots for Agriculture (1980), and the term didn’t emerge in popular usage until the late 1980s.” (“A Brief History of Sustainable Agriculture,” by Fred Kirschenmann, in The Networker, vol. 9, no. 2, March 2004.) However, the idea of agricultural sustainability – stewarding the food production resource base for use of future generations – is not a new phenomenon.
Sustainable agriculture can be defined in many ways, but ultimately it seeks to sustain farmers, resources and communities by promoting farming practices and methods that are profitable, environmentally sound and good for communities. Sustainable agriculture fits into and complements modern agriculture. It rewards the true values of producers and their products. It draws and learns from organic farming. It works on farms and ranches large and small, harnessing new technologies and renewing the best practices of the past.
In short Sustainable Agriculture is:
• Economically Viable: If it is not profitable, it is not sustainable.
• Socially Supportive: The quality of life of farmers, farm families and farm communities is important.
• Ecologically Sound. We must preserve the resource base that sustains us all.
Beyond the Congressional definition, sustainable agriculture has been defined in several ways, for example, as a system that can indefinitely sustain itself without degrading the land, the environment or the people. It reflects our concern with the long-term viability of agriculture.
Dr. John E. Ikerd, Extension Professor at the University of Missouri, offers his view of sustainability: "A sustainable agriculture must be economically viable, socially responsible and ecologically sound. The economic, social and ecological are interrelated, and all are essential to sustainability. An agriculture that uses up or degrades its natural resource base, or pollutes the natural environment, eventually will lose its ability to produce. It's not sustainable. An agriculture that isn't profitable, at least over time, will not allow its farmers to stay in business. It's not sustainable. An agriculture that fails to meet the needs of society, as producers and citizens as well as consumers, will not be sustained by society. It's not sustainable. A sustainable agriculture must be all three - ecologically sound, economically viable and socially responsible. And the three must be in harmony."
However it is defined, sustainable agriculture will affect how you operate your farm or ranch.
