Red Meat

I was thinking about writing a short post about all the academic history I’ve been finding at the bottom of some pretty popular books recently.  Alfred Crosby’s ideas about the Colombian exchange in Charles Mann’s 1491, for example.  Or Vaclav Smil’s story of the Haber-Bosch process for fixing atmospheric nitrogen, from his Enriching the Earth, in Simon Fairlie’s 2010 book, Meat: A Benign Extravagance.  Maybe it’s no coincidence that these are both canonical environmental history texts (they were both on my field list, thanks to my EH advisor, Ted Melillo).  Perhaps because their interest is on the edge of science, readers of popular books on environmental issues are more open to the fairly dense technical arguments.  Maybe it’s easier to move ideas from academic books to popular.  But I’m not so sure.  Science writers often have a lot of skill taking excruciatingly complicated stuff and making it comprehensible to the rest of us.  Michio Kaku, Brian Greene, Matt Ridley, and Colin Tudge are just a few of the names that jump to mind.  Richard Dawkins was Oxford’s “Professor for Public Understanding of Science” until 2008.  We could probably learn a thing or two from these authors.

And Simon Fairlie’s book is part of this tradition.  Fairlie is a British farmer and writer, and a former editor of the British environmental journal The Ecologist.  His book about meat’s place in the food chain draws heavily on Vaclav Smil’s work on nitrogen fixation, and digs a little more deeply into the downside of the green revolution Smil describes.  But the thing that really jumped out at me as I read Meat was Fairlie’s response to the famous food-mile study that stunned us all a few years ago. 

You may recall the article “Food Miles and the RelativeClimate Impacts of Food Choices in the United States,” written by Christopher L. Weber and H. Scott Matthews of Carnegie Mellon for Environmental Science & Technology in 2008.  It made headlines outside of the science community because they concluded that “eating local” was not a very good way to reduce greenhouse gases.  Eliminating red meat from your diet one day a week, they said, would reduce your carbon footprint more than going 100% local.  This came as a shock to many people who had embraced local farms and markets as a way of living more sustainably.  I was TA-ing an Environmental History course when the article became a news item, so I had my students read it and discuss.

There are a number of possible responses to a claim like this, and the students were able to see many of them.  They pointed out the social benefits of farmers’ markets and local food, the fact that most Americans get their meat from feedlot-style animal husbandry*, and they concluded that they might get even better results if they did bothrather than choose to be local or to be part-time vegetarians.  Fairlie touches on each of these points, and then he drops his bomb.  What the study doesn’t deal with – what we overwhelmingly urban Americans routinely fail to see when we look at the local question – is on the back end.  The issue isn’t raising food and getting it to market.  The issue is, getting the waste back to the farm. 

Throughout history, there has been a rough symmetry between the input and output sides of agriculture and life.  Food came out of the earth; crop residues, manure, and even human waste went back in.  Then came the era of flush toilets, food miles, and landfills.  Industrial fertilizers now fill in for the nutrients that came from all that missing waste, but they cost a lot, they run off into our water, and they don’t keep the ground from compacting and eroding the way organic material does.  And assuming for a moment that either soaring global demand or peak oil is going to push the price of energy way up in the future, it’s easy to see that the days of cheap nitrogen may be numbered.  So Fairlie’s point is an important one: if we don’t account for getting waste back to the farm, we’re ignoring a big factor in the true cost equation.

Economists have a word for this.  The things we ignore in our models and analyses are called “externalities.”  At first, they’re left out because they’re either difficult to price (like airport noise in the 1950s) or because they’re ubiquitous and “free” (like rivers and the ocean used as sewers in the 19th century).  Later, they’re ignored because they raise difficult questions about private ownership and public responsibility that free-market ideology would rather bypass.  And sometimes it takes someone like Fairlie, who lives on a farm, to remind the city-folk that just because you flushed your toilet or dragged your trash to the curb, the story isn’t over.  I personally suspect that all our problems arise from ignoring externalities.  Sounds like another book project . . .

But maybe you have to be 2/3 of the way through Fairlie’s book and already buying into his vision, for this to be a powerful “Aha!” moment.  I may not have done justice to it here.  Read the book as an example of how cutting-edge Environmental History can be turned into a best-seller, and you’ll also discover Fairlie’s answer to Garrett Hardin’s “Tragedy of theCommons.”

* I asked the authors about grass-fed beef and other sources of “red” meat, and Weber responded to my email, saying that “other red meats than corn fed beef do have the same high emissions” because of the methane-producing effect of digesting grass and the typically longer lifetimes of sheep and goats.  So in the view of these scientists it’s not just a feedlot issue.

Blueberries

Dan Allosso

When I read old books, I’m always on the lookout for references to other old books, or to topics that were relevant when the book was written, but that may not be well known now.  These sometimes lead in new and surprising directions.  There were several things in Bolton Hall’s Three Acres and Liberty, the book that launched the back-to-the-land movement in 1907, that seemed to deserve more investigation.  The thing that really jumped out at me, though, was a passing remark he made about blueberries.

In spite of being a hardy native plant that the Indians had harvested from time immemorial, Hall says “with our present knowledge of the blueberry, it is doubtful if it can be made a commercially cultivated crop.”  This surprised me, since one of my family’s favorite activities when we lived out East was picking blueberries at a big berry farm in the shadow of Mount Monadnock.  But Bolton Hall was no dummy.  Three Acres and Liberty describes a variety of intensive gardening techniques that are popular today (and that many people think were invented by their current proponents), including the use of manure instead of commercial fertilizers; “super close culture,” where plants are set very close together to use the land and water efficiently and keep down weeds; “companion cropping” and “double cropping,” to extend the growing season; rotation to reduce the impact of pests; soil inoculation using nitrogen-fixing legumes (just recently discovered when he wrote); mulching to save water; raising chickens, ducks and rabbits to use waste and produce food and manure; canning and drying to preserve even small quantities of food; and even disposal of city sewage by using human waste on urban gardens.  So I had to believe he was right about blueberries not being commercially viable in 1907.  And of course, the obvious next question was, when did this change?

Apparently, Hall wrote those words just about as late as he could have.  Commercial blueberry production began in Maine in the last quarter of the nineteenth century, but the source of the berries were native plants that propagated themselves and spread as they had always done.  The only change was that growers removed the surrounding trees to give the blueberries more room and light.  However, in 1911 a New Jersey woman named Elizabeth Coleman White (1871-1954) read a USDA Bulletin about experiments in blueberry propagation.  She invited the bulletin’s author, botanist Frederick Colville, to the New Jersey pine barrens, where blueberries grew wild as they did in Maine.  White and Colville got the locals, who picked the wild berries regularly, to tag the bushes where they found the largest fruits.  They asked the local pickers questions about taste, time of ripening, plant vigor, and disease resistance, and brought the best plants back to the family’s farm in Whitesbog.  By 1916, White and Colville had created the “Tru-Blu-Berry,” America’s first commercial blueberry.  In 1927, White helped organize the New Jersey Blueberry Cooperative Association, which still exists today.

I’ve only scratched the surface of this story – there’s a lot that could be done with a topic like this! – but the thing I like most about it is that White and Colville were smart enough to use the expertise and local wisdom of the poor folk, the “pineys,” who went out into the barrens to pick wild fruit.  The Progressive Era is remembered as a time when top-down, expert-driven solutions became all the rage.  Often these scientific innovations were imposed on rural people without consultation, much less consent.  And often these changes were much less valuable and lasting than the experts promised.  So it’s great to find a story where the innovation came from a cooperative process, and led to a tangible and lasting improvement.  I’ll think of this next summer, when I pick the fruit from the eighteen blueberry plants of half a dozen varieties I planted this fall.

Good Fences

Dan Allosso

Robert Frost famously epitomized New Englanders with the wry phrase, “Good fences make good neighbors.”  But even if your neighbors are far enough away for comfort and you like them, fences have their uses.  I’ve been thinking about these as I continue to work on 19th-century American history while starting up a small farm in the upper Midwest.  It’s interesting, because I suspect I’m living through a moment of historic change, and it’s all about fences.

In addition to influencing the relationships of neighbors, I’m learning fences have a number of other uses on the farm.  Of course, they help keep your animals where you want them.  And hopefully they help keep predators off your animals.  And they may keep wildlife off your vegetables, although hungry deer will jump any fence less than eight feet high.  Less obviously, though, fences define our relationship to the land and the uses we can put it to.

Most everyone is familiar with the story of the colonial split-rail fence.  There’s one on the cover of William Cronon’s Changes in the Land.  The rail fence, roughly cut from the timber settlers needed to clear in order to turn wild eastern forest into farmland, symbolizes European ideas of land use and ownership that settlers brought with them and imposed on the environment and the natives they found there.

This style of fencing was cheap and easy where settlers found trees needing to be cleared.  I took this photo at the Genesee Country Village and Museum in western New York.  This section of the museum represents life around the year 1800, when farming was a family enterprise done with ox, horse, and human power (I spent a 4th of July weekend in that cabin with my family as "The 1800 Farm Family").  An energetic farmer could clear about seven acres of land in a year, and often the family farmstead was split between a small cultivated field, a pasture for grazing animals, and a woodlot for fuel.  As families moved west, however, they discovered plains of prairie grasses that towered over the heads of children like Laura Ingalls.  The wooden fences of the East were impractical in many parts of the Midwest, where lumber came from far away at great expense, and was reserved for building things like houses, barns, churches and saloons.  And without internal combustion and irrigation, much of the land farther west was unfit for cultivation, but ideal for grazing if the animals could just be contained.

Joseph Glidden (1813-1906) was a New Englander who moved to Illinois in 1843.  He patented barbed wire in 1873 and died a millionaire.  Among his holdings were 335,000 acres in Texas: range land that his invention had allowed to be fenced.  The enclosure of the rangelands is one of the mythic moments in the story of the American West.  Through books and movies like The Virginian (1902), Oklahoma (1943), Shane (1953), Heaven’s Gate (1980), and Open Range (2003), it is as central to popular western history as Frederick Jackson Turner’s comments about the closing of the frontier are to the academic West.  Barbed wire fences dramatically expanded our ability to affordably control very large spaces.  Once again, Americans were able to impose our vision on the land (and also, once again, on the Indians).

Fences remain important to farmers, and their use is still a complicated affair.  Cattle and horses can be grazed on pasture enclosed by a few strands of barbed wire.  Sheep, with thick fleeces to protect them, will go through barbed wire.  Goats are even harder to contain – there’s an old saying that if your fence won’t hold water, it won’t hold goats.  And although chickens will usually come back home in the evening, there are a lot of varmints out there that will eat them in the meantime if they aren’t protected by a fence.  Farmers have used woven wire, hardware cloth, rigid panels, and electric wire to contain and protect animals.  Each comes at a price, and it adds up: a decent four-foot high sheep and goat fence will run you over a dollar a foot.  So these fences tended to be expensive and permanent.  Most small farmers use and endlessly reuse a variety of materials based on what they can get cheap, and hoard the bits they aren’t currently using.

As sustainability and soil depletion have come into sharper focus in recent years, innovative farmers have rediscovered what the old-timers knew before the age of chemical fertilizer: pastures will support a larger number of animals if they are grazed in succession.  Sheep and goats prefer to eat different plants than cows, so they can coexist with cattle on a pasture without competing.  And then the poultry can follow, eating bugs out of the droppings; which not only breaks up the fertilizer and spreads it over the fields, but also actually reduces the number of parasites and pathogens.  This is a win-win-win, the animals are better off, the farmer produces a larger quantity and wider variety of protein on a given plot of land, and the land itself is improved in the process.  The only catch is, you have to enclose and protect all these different types of creatures!  

That’s where the story gets interesting.  The cost of fencing has traditionally made it difficult for farmers to fence appropriately for intensive pasturing, and the effort involved in setting and moving fences has made land use inflexible.  But recently, battery-powered low-impedance fence chargers and moveable electric fences have changed the game again for small farms.  Deep-cycle batteries like the ones in your boat or RV can run miles of low-cost electric tape, twine or netting.  They can even be hooked to solar chargers.  And they’re easy to set up and move, allowing farmers to raise temporary paddocks and move animals as quickly or slowly as needed over the land.

This may not seem like such a big deal, but I think it may turn out to be.  The world’s food supply depends heavily on fossil fuels, both for transportation and for the production of synthetic fertilizers like anhydrous ammonia.  It currently takes fifteen calories of energy to put a calorie of food on your table.  If there’s any truth to either climate change or peak oil, multi-thousand acre cornfields and factory-style feedlots may turn out to be as much of a twentieth-century anomaly as McMansions and jet-setting to conferences.  But it has been suggested that the world’s food needs could be met by intensive techniques combining grazing with gardening.  Farmers like Joel Salatin claim that not only would intensive pasturing solve the world food problem, but “in fewer than ten years we would sequester all the atmospheric carbon generated since the beginning of the industrial age” (Folks, This Ain’t Normal, p. 195).  If true, this is a really big deal; and even if Salatin is not quite right about this, intensive pasturing still seems like a really good idea.  And these new fences make it possible.  That could be historic.

Advice to Farmers

Dan Allosso

People have been giving advice to farmers throughout American history.  Sometimes farmers themselves have written about their favorite techniques or innovations, but often experts have tried to compile the “best practices” of the past and add new ideas developed by scientists and technologists.  The progressive era amped up this process, and turned the USDA and land grant “Agricultural and Technical” universities into big producers of information for rural people.

But that process is a story for another day.  Today, what caught my attention is an old (1880) book I found in the UMass library stacks, called Farming for Profit (online here).  Written by John Elliot Read (who claims in the introduction to be “a practical farmer, acquainted with the details of farm management, and thoroughly used to manual labor”), the book promises to show “How to Make Money and Secure Health and Happiness on the Farm.”  I think it’s interesting that even a volume designed to be an “Encyclopedic” and “Comprehensive” source of “Mechanics” and “Business Principles” in 1880 puts the rural lifestyle front and center.

Farming for Profit is a fascinating combination of late-nineteenth century technique and culture—both of which can be compared with what came after.  At some point, I’m going to make a more thorough study of how the two elements of farm tech and farm life changed over time.  For right now, I thought these items were interesting:

In the illustration at the top, across from the title-page of the book, we get a more or less classical view of farm life—not of technology.  There are no new machines in the picture, and the buildings don’t even seem to be in the best repair.  The impression I get is of an ancient and venerable way of life.  Peaceful, slow-moving, and dignified.  Later in the book, there are more practical illustrations, like this diagram of an ideal farmstead.  And in another illustration, we see more evidence of a transition in farming: the first view is of corn plants (old-fashioned ones, not the super-hybrids we're used to seeing today) that have been “drilled or planted,” while the second shows corn planted in hills.  Hill-planting was the old technique colonists learned from the Indians, so it’s interesting that it still finds its way into a manual from 1880.  That suggests that maybe the author was a practical farmer with lots of experience in the fields.
