Conservation: A Misused Word

Today's blog post is an excerpt from a 1965 Journal of Soil and Water Conservation article by Lauren K. Soth:

The word “conservation” is saturated with goodness. Like patriotism, democracy, the family and motherhood, it is suffused with an aura of virtue. Sometimes this aura gets in the way of rational discussion. As a political label, conservation can cover a multitude of activities which may or may not be true conservation but which are regarded automatically as wise and valuable. …

There is a difference in practice, obviously, between conservation of a renewable resource and of one that is exhaustible. Conservation of tin is not the same procedure as conservation of timber. Conservation may be the extension of the time of se of an exhaustible resource—or the withholding of all use until a later time. Or conservation may be the planned use and renewal of renewable resources so as to maintain a desired level of supply of a product. This kind of conservation is the kind we are talking about most often in agriculture.

The definition of conservation also varies with the state of the arts and of knowledge. A farm practice which at one time was truly called conservation, because current knowledge indicated that this practice conserved the soil, may at a later time be judged not to be conservation.
Advances in technology of land use in recent years have shortened the renewability time of depleted crop land. Our thinking about what constitutes “destruction” of land for crop production has had to be revised. Even the disappearance of the top soil no longer can be regarded as the end of the chain of resource use. New top soil can be built; and in some instances crops can be economically grown on properly treated land which has eroded to the subsoil. Wise use of land may sometimes consist of cropping it to a low state of fertility and even to the loss of several inches of top soil. …

The point here is that there are no absolute values in conservation of soil. There is no absolute virtue in the word or in the practices followed in its name. Public policy in this field should be based on facts, knowledge, experience—not on emotion. …

If the “conservation” funds used to stimulate better farm methods were labeled as such (or as subsidies to farmers), the public might still prefer to continue them in full. But at least the people ought to know what these funds are accomplishing and not be misled into thinking they are for true conservation.

When public funds are used for retiring land from crop production for a long period, or for converting it to a less intensive use, that is genuine conservation.

The consequences of land use fragmentation and livestock herd size

The Journal of Soil and Water Conservation recently published work on the impact of land use fragmentation and larger herd sizes on manure recycling energy and cost. (See Bartelt and Bland 2007; Journal of Soil and Water Conservation 62(5):345-352.)

What does that mean? It may sound kind of technical and esoteric at first, but the research addresses an important conservation issue in today’s changing landscape.

Bland summarizes the trend as follows: “Uses such as housing and recreation fragment the formerly contiguous areas of land that once surrounded many farmsteads, so farmers increasingly must travel past and work adjacent to lands used for purposes other than agriculture. At the same time, livestock herds are consolidating into fewer and larger units…. Environmentally sound recycling of manure from ever-larger herds requires greater energy and planning for transport and spreading within a landscape that is a mosaic of land uses.”

Is this fragmentation and diversification of land use occurring in your area and, if so, what has been the impact? Have manure hauling costs risen significantly? Has this affected manure recycling practices? Is this an opportunity to develop more efficient manure-management systems or should land development and herd sizes be called into question?

Are you aware?

Are you aware of the report published in dec 07 by Khan et al of the U. of Illinois which confirms that the long term use of chemical fertilizer releases carbon from soil and reduces soil organic matter? This was also confirmed by studies released by rodale and Iowa State in the first quarter. I think people are generally aware of the destruction of water quality in the gulf and chesapeake Bay caused by row cropping but are they aware of the tie to CO2 emission?

Washington Update

The U.S. Congress has one more week prior to taking their Easter recess break March 15-30th. Efforts to finish a new Farm Bill will probably require an extension of the 2002 farm bill beyond March 15, 2008. Speculation is that it could be for one month. However, some have suggested for at least one year. The reasons for delay in sending a new bill to the President include: spending above the 10-year baseline budget set by the Congressional Budget Office (CBO) The Administration has offered to go $10 billion over the budget but have asked Congress for major subsidy and funding reforms. These include a cap on payments to certain producers, not raising loan rates for producers, and changing some measures to protect sugar producers.
The Administration has also asked for budget offsets for the increase above the budget baseline. Some of the recommendations would be changes in Dairy Support, Crop Insurance, Planting Restrictions, Food Aid, and Disaster Funding.

Meanwhile key Agriculture Committee staff members have been meeting to make recommendations to Conferees on many items that are not the same in the House and Senate bills. House Agriculture Committee Chair Peterson has said he believes a farm bill deal can be struck before March 14.

The Food and Agricultural Policy Research Institute (FAPRI) released their U.S. Baseline Briefing Book: Projections for Agricultural and Biofuel Markets. It is a 68 page document. FAPRI is headquartered at Columbia, Missouri.

Combine environmental stewardship and professional advancement in a conservation career

It is an exciting time for people who care about the environment and are choosing career directions. The environmental challenges are great, and the ways to be professionally engaged in protecting environmental resources are numerous. The result is you can forge a career path that is both professionally interesting and personally rewarding.

Conservationists don’t necessarily have “conservation” in their job title. In fact, what makes conservation work so stimulating is partly the interdisciplinary interaction of the people involved. Soil and Water Conservation Society members, for example, include economists, agronomists, geologists, biologists, geographers, engineers, ecologists, landscape architects, soil scientists, computer scientists, and the list goes on. In addition to the wide range of disciplines, conservation careers include a wide range of job types—from technical advisers to researchers to educators to technology developers to policy makers, etc.

Collectively, these scientists and professionals contribute to the cause of healthy land and clean water.

It is also a good time for people mid-career who might be ready for a professional change or could benefit from enhancing their professional achievements with a sense of greater purpose and personal pride—that is, through a focus on sustainable natural resource management.

Whatever stage in your career, look into the future and imagine your retirement celebration. Wouldn’t you like people to say not only was this person a great _____ (professor, program manager, technician, or whatever the case may be), this person also stood for something—smart, sustainable use of our natural resources. This person’s work made a difference in the world. This person made a real contribution to protecting our environmental resources for future generations. This person can be you.

The knowledge, tools, and partnerships necessary to achieve this vision can be accessed through membership in the Soil and Water Conservation Society. The society’s publications, events, and other services allow its members to learn from each other across disciplines and work together in innovative partnerships—all in the cause of advancing sustainable use of resources for healthier land and cleaner water for years to come.

Opening a can of organic worms

As a forum for the science behind the soil conservation movement, the Journal of Soil and Water Conservation regularly provides analysis and guidance related to no-till farming. No-till has been shown to result in significantly less soil erosion than conventional tillage.

The journal recently published a pair of stories related to tillage and organic farming systems. Organic farming is not a tillage system, but tillage is typically used in organic farming for weed control since chemical herbicides are not employed.

The first article was a summary of research conducted by the USDA (Teasdale 2007). The article explained that many organic farmers and no-till farmers share the same goals—using a production system that maintains soil fertility and sustainability. In the study, organic farming systems generally provided greater soil health than nonorganic no-till systems largely due to increased soil organic matter.

The second article presented two case studies of producers who switched from conventional farming to organic farming with minimum tillage (Rainford 2008). The farmers believed this change was environmentally beneficial. In addition, they have experienced a number of economic and productivity benefits as a result.

These seemingly simple articles have resulted in more letters to the editor and controversy than any other topic in recent months. The comments cover the spectrum from those who were upset to see the articles because they believe organic farming is an “environmental disaster” (because of its reliance on tillage) to those who thought the articles were an important new contribution to the literature.

“Organic” has certainly become a politically charged word. Some claim the basis for the antagonism is competition for financial assistance; some claim it is a misunderstanding of terminology. Is there more to it? Are both sides really only interested in protecting the environment? Do conservationists dare touch the topic? Is there a place for nonpolitical, science-based discussion of organic agriculture and natural resources? Do the pro-organic and anti-organic voices drown out the neutral, analytical ones?
