Build a 1200 sq ft High Tunnel for $1500

What This Is

I wrote this post with the hope of helping small-scale farmers build a large, sturdy and economical high tunnel. This design is perfect for winter growing, and can also be used (with a shade cloth replacing the poly skin) for season extension in the summer.

Our high tunnels are 100’ long and 12’ wide, to suit our 100-foot bed length and 3’ bed width with 1.5’ aisles (3 beds per tunnel). The total cost is about $1500, which is a steal for a high tunnel this size (even if it is a few bucks more than the designs it’s based on, for reasons we’ll discuss down the page). Better yet, this is a project that three people could easily manage in a day, even on the first try.

With a little practice you and your two friends could pop up three of these in a good day.

This post relies on two links, in particular: first, Johnny’s excellent 27-page guide to building a high tunnel; and second, Mother Earth News’ diagram of a high tunnel end wall frame.

What To Do

If you want to build our high tunnel, here’s what you do. First, check out the materials list and order what you need (but don’t actually do this first–go ahead and read through everything). Second, proceed as if you were going to build Johnny’s high tunnel, until you get to page 17, where they tie off the plastic in an unsightly and ungainly ponytail and wedge it between two T-posts. Don’t do that.

Instead, follow Johnny’s high tunnel construction plans about 80%. Basically, we build the tunnel according to Johnny’s excellent plans until the very end, when it comes time to tie off the plastic on the end walls. For this step, we use a simple framing approach recommended by Mother Earth News (MEN) and many others.

The advantage of Johnny’s plans is that they are geared toward a simple, strong and highly economical structure. For example, where MEN uses PVC pipe to construct the bows, Johnny’s uses steel fence rail. And instead of requiring hundreds of feet of wiggle wire/track, Johnny’s uses a nifty lacing of parachute cord (total cost: $50) to hold the plastic in place while allowing for easy adjustment up and down.

The disadvantage of Johnny’s plans, as far as we’re concerned, is the absence of a door (or doors). Instead, the ends of the poly skin are simply tied off and staked down. Users crawl in and out under the liftable poly cover on the sides. There’s nothing wrong with this approach. However, there are two disadvantages that led us to build proper end walls with working doors.

First, Johnny’s design assumes two extra aisles inside the high tunnel, one on each side. We prefer to maximize the growing space and run our beds to within inches of the side. In so doing, we actually get a lower cost/square-foot of growing space as compared to Johnny’s design, despite the extra $150 or so it costs to build the end walls. Second, it seems truly inconvenient to slide under the poly skin every time you want to get in or out, especially if you are toting tools/harvest bins/wheel barrows with you. It just seems like a really easy way to put a hole in the (expensive) poly siding.

Enter the MEN’s plans. Many people have built a simple frame for their end walls, but we chose to highlight the MEN diagram for its simplicity. The end wall frame is constructed of treated 2×4’s, with a bottom end board of treated 2×6. You can easily adjust the dimensions to suit the particular widths of your high tunnel and, especially, your door.

Now for our own design touch. We then run dual-track wiggle-wire channel along the top arc of 2×4 frame, and a single-track channel along the doorframe and the 2×6 on the ground. This allows us to attach the large poly skin to the top of the double-track, and then cut pieces of poly to fit on either side of the door.

Materials

This greenhouse materials spreadsheet (including links to all the materials) should get you started. (If you decide to lengthen/shorten your high tunnel, check out Johnny’s helpful worksheet, which customizes most of the material list depending on the length you’re trying to build).

Note that some of the materials for this project are from Johnny’s. Their pole-bender is a good investment at $60 even if you’re only planning to build one high tunnel, because it allows you to make near-perfect bends in any standard 1-3/8” top rail fencing. The first time we built a high tunnel, we bent all of the bows by hand using a jig we rigged up from two T-posts and a telephone pole (the result was impressive considering, but the time and stress were nothing near worth it). Johnny’s also sells a nice piece of poly cover (24’ x 125’) that will work very nicely for this 100’x12’ design, including enough extra material on the ends to cover the end walls. If you’re looking to save a little money, these plans replace Johnny’s film with good stuff from littlegreenhouse.com, which shaves about $50 off the total cost. Finally, Johnny’s sells the appropriate cross-connectors that will attach the bows to the ridgeline. These can be hard to find elsewhere in the proper dimensions, and again, they are reasonably priced at $5 for two.

We’ve listed Farm Tec as a good supplier for wiggle wire and the wiggle wire track. This stuff is not cheap at over $1/ft, but good luck finding it cheaper anywhere else. If you do, get in touch!

Just for kicks, I’ve linked to Bolt Depot for all of the (literal) nuts and bolts required for the project. They are a great resource for any kind of fastener, and they have excellent prices. But please note that these (or comparable) materials could be picked up at just about any home improvement store. Ditto for the parachute cord from parachutecord.com—you could find it a lot of places, but $54 is cheap for 1000’ of quality cord.

We’ve included links to Lowe’s for the remaining materials. They could be acquired just as easily at any home improvement store.

What it doesn’t include:

Doors (you can usually find used glass doors at places like the Habitat Re-Store or other used building supply stores). You’ll want to buy your doors before you go about framing the walls, since the dimensions will depend on the door.

Hinges, if the doors you buy don’t have them.

Wood Screws, since you’ll probably have some laying around.

Duct Tape. Duh. Especially useful for wrapping around the joint between the bow pole and the post pole, to prevent tearing on the poly. Similarly, for buffering the end of the ridgepole so that it doesn’t tear at the poly.

Good Drill Bit. ¼” for drilling into metal.

AND…Basic tools, including a drill, a heavy mallet, measuring tape, a hacksaw or reciprocating saw to cut the posts (or have the home improvement store do it, as we did), and a plumb line if you’re super anal.

 

A Room of One’s Own

Since Emily and I sowed the inaugural bed of romaine lettuce in March, 2011, hundreds upon hundreds of community members have graced the Duke Campus Farm with their toiling hands and sweating brows and triumphant laughter.  Our workdays, festivals and workshops have attracted students, faculty, media, chefs, out-of-towners, and top-level University administrators.

Through it all, we’ve tried to foster a community space that evokes a modernized version of the Jeffersonian ideal. As Jefferson wrote in 1781, “Those who labor in the earth are the chosen people of God, if ever he had a chosen people, whose breasts he has made his peculiar deposit for substantial and genuine virtue. It is the focus in which he keeps alive that sacred fire, which otherwise might escape from the face of the earth.”

Alas, it seems that while the Duke Community is eager to tap DCF’s deposit of “substantial and genuine virtue”, while they are keen to “keep alive the sacred fire,” while they willingly toil in this little square of paradise on the edge of the Duke Forest, sometimes nature calls them back into her bosom. That is, sometimes they have to pee and poop.

Until recently, Farm staff had few answers to the squeamish pleadings for a place to find relief. We meagerly pointed to the nearby forest in what amounted to an apology more than a solution.

Today, I am pleased to write, we can do a whole lot better. Thanks to Green Grant funding from the Sustainability Office, and the patient work of many hands, the Farm celebrates the opening of its very own outhouse. It is, to quote one user, “certainly the nicest outhouse in Orange County.”

If you’d like to take a virtual tour, Bryan Roth over at the Duke Communications shop has prepared a lovely little video.

Since the outhouse project began, I’ve had a lot of questions about its purpose, design and construction. I’ll try to answer a few common questions here. Feel free to add your own in the comments, and I’ll do my best to respond.

Why build a pit privy instead of a composting toilet or an artificial wetland?

I’ve gotten this question many times, including from one disgruntled reader on Duke Today who expressed her “shock” and “disappointment” that we would build such a primitive structure. The simple answer is that we tried—really tried—to convince Orange County to permit a composting toilet. After all, the Duke Campus Farm strives to minimize our external inputs and, to be blunt, poop can be an excellent and safe source of plant nutrients. We wouldn’t have used the compost (aka “humanure”) on any vegetables, but we could have used it to grow a rainbow of zinnias and sunflowers. Alas, the gods that be in Orange County were having none of it. So much for a progressive county, huh?

As far as artificial wetlands go, I think it’s a great idea. I helped design the artificial wetland that processes the brown water at the Montessori School of Raleigh Middle School in rural Durham County. It’s a lovely system, complete with plant-lined berms, a UV-light and a constructed wetland. It also cost about $100,000 to build, or about 10X the annual operating budget of the Farm. If anyone is looking to cement their legacy, the Farm is happy to offer naming rights for the wetland successor to the outhouse. Email emilysloss@duke.edu.

 

Why did you build such a nice structure? Isn’t it just a hole in the ground?

Another common question. It’s true that the outhouse cost $1,000 in materials alone, not to mention over $600 in permitting fees and non-negligible labor costs. It has ample space inside, two sliding windows, a Dutch door, and a small library.

The answer is several-fold.

First, I’m out at the Farm a lot. Emily, Sarah, Damon, Anna, and others are out there even more. I want a pleasant place to do my business and I imagine that they do, too. While I’m “busy” I like to watch the deer that mosey on the edge of the Duke Forest, and watch the sunset out the window as I catch up on the latest issue of Mother Jones.

Second, there is a growing perception of farming as a second-class occupation, dirty work, even uncivilized (ironic enough given agriculture’s leading role in the birth of settled society). The Duke Campus Farm exists to, among other things, renew the image of farming as a rewarding, attainable and, yes Mr. Jefferson, virtuous occupation. Even—ahem—for young people with a world-class education. Farmers should not be relegated to a dark cramped putrid bathroom any more than they should not go to the opera or enjoy world-class healthcare.

Finally, the Farm is a center of community. Beauty inspires community. Comfort facilitates community. If we can’t be proud of what we build together, with our hands, we will surely struggle to build something worthy in the intangible dimensions of community space. Or, as Emerson wrote, “I have heard that stiff people lose something of their awkwardness under high ceilings, and in spacious halls…to teach us manners, and abolish hurry.” Indeed.

What qualified you to build this thing in the first place?

Stubborn patience, an abundance of time, and really well-written and specific building plans.

Drought, You, and Yellow #2

2012 Iowa Yellow #2 corn, from Emily and my trip to Iowa earlier this month

It’s been a while since I’ve posted anything on Ag Policy here, but Tuesday night’s Colbert Report offered a golden opportunity to discuss a few of the key features of our industrial ag system. Unlike some past posts, I’ll try to stick to the (self-explanatory) facts rather than rail against the system itself. You can judge for yourself whether the system we’ve got is the one we want.

In the clip, Colbert plays a funnier Michael Pollan (no disrespect, Michael) while speaking to Bruce Babcock, professor of agricultural economics at Iowa State University. Watch the clip first, then read on!

Watch the video here (sorry, WordPress doesn’t let you embed flash into their blogs)

The interview begins with issues of scale. As Mr. Babcock states, “Iowa is corn country.” Here are the facts: this year, the blanket of corn covers 41% of Iowa’s exquisitely fertile land. Iowa planted almost 15 million acres of corn this year, or 15.5% of the 96 million acres of corn in the U.S. As a reference, America produces about 40% of the total corn harvest for the globe.

The interview continues to the issue of rainfall. Perhaps surprisingly, corn remains almost entirely un-irrigated in the U.S. Farmers depend on seasonal rains to produce a solid yield. This means that irrigation infrastructure doesn’t exist across most of the Midwest. (Personally, I think we should be grateful for this. The Oglala aquifer that underlies most of the land is expected to dry up in the next decade or so, even without irrigation of the nation’s most prevalent crop). When it doesn’t rain, there is little that can be done. And it’s not raining in Iowa, or in most of the Corn Belt.

Next, Colbert turns to the corn crop’s effect on food prices. According to Babcock, “You don’t need to worry about [the price of] soda pop or corn chips or corn on the cob.”

Why?

Well, the short answer is that soda pop and corn chips have a much smaller percentage of the corn price embedded in their sales price. This is a difficult point to make sense of. A useful analogy may be to compound interest. Products that use corn directly, such as soda pop and corn chips, use corn directly to produce the (diabetes-causing, heart-disease ensuing) goods. The cost of rising corn prices effects these good directly, but tend to get swamped by the cost of energy embedded in their production and shipping, and the cost of selling them embedded in marketing and labor.

And corn on the cob?  Corn on the cob is “sweet corn,” e..g. the corn you can eat directly without processing. It’s a very different incarnation of zea mays that makes up less than .3% of the America’s corn production.

The corn Professor Babcock was talking about? Fieldcorn, or Yellow #2 as it’s known on the street, a commodity defined only by its “0.2% or less heat damaged kernels, up to 5.0% damaged kernels and up to 3.0% corn or foreign materials.” If you walk into a field of Yellow #2, peel back the husk and dive right in, you’ll repeat the same earth-shattering experience I did as a child. The stuff is inedible, at least before it’s processed or fed to livestock.

In any case, as Prof. Babcock points out, “What you need to worry about is the eggs and chickens and dairy products…your beef and your pork.” Eggs? About 70% corn. Beef? 93% corn, according to Scientific American. That’s about half the corn, give or take.

Most of the other half, “About 35-40%,” goes to ethanol production. With a LOT less corn to go around for the next year or so, the feedyard operators and ethanol producers are in a bidding war over Yellow #2. In any normal market, the ethanol people would have packed up and gone home months ago, resigned to not make ethanol this year. It’s a highly inefficient process, after all, and people won’t pay $10/gallon for it.

Instead, more corn is going to ethanol this year than in any year in history thanks to the federal Renewable Fuel Standard. The RFS mandates that gasoline makers blend some 15 billion gallons of ethanol into their gas this year. Since the requirement isn’t based on price, ethanol producers can charge whatever they need to break even, which means they can pay whatever they need to buy the corn “feedstock.”

Farmers who can’t afford to feed their cattle will dump them on the market. If you have a deep freezer, this would be a really good time to buy two years’ worth of beef. Better yet, corner the market. The point is that prices will rise steeply once the glut is off the market.

Finally, lest you lose too much sleep fretting for our brethren in the Midwest, the interview turns to crop insurance.

Babcock: “90% of Iowa farmers have crop insurance. It’s a federal program…”

Stephen: “A federal insurance program? That’s just Obamacare for our corn.”

Babcock: “Well, in essence, you are right.”

He is right, in the sense that the vast majority of commodity crop farmers carry insurance, covering up to 85% of lost revenues, heavily subsidized by the government, and with none of the most basic environmental protections required by other farm subsidies. Ironically, heavily subsidized federal crop insurance is part of the reason we have 95 million acres of corn. Federal crop insurance has systematically taken the (private financial) risk out of industrial monocultures, removing any incentive to diversify what is grown in the field (the best form of “natural” insurance). Taxpayers are paying farmers to make riskier bets, and we pay again when those bets bust in the form of emergency aid packages.

Now is the time to bring a little sanity back into the picture. For one, the five-year federal farm bill is up for renewal; it’s our best chance to trim the subsidies and pseudo-subsidies (i.e. RPS standards) that have exacerbated this “disaster.” On the other hand, bad farm policy didn’t make the weather. Consider this closing exchange from the interview:

Colbert: “Is this the worst drought of our lifetime?”

Babcock: “Well, it depends on how old you are…”

Mr. Babcock’s answer gives a nod to the severe drought of the 1930’s that led to the Dust Bowl. Yet the obvious answer, for anyone who has been paying attention, is “This may be the worst drought you’ve ever seen, but it won’t be.” The right answer is that it depends on how young you are. If you are not super-old or terribly infirm or particularly danger-prone—if you’re planning to stick around for a few more years—you’ll see a worse drought than this in your lifetime. More likely, you’ll see a dozen.

 

 

Why Aren’t All Farmers Driving Gold-Plated Tractors?

I recently ran across this policy briefing,  “Still Waiting for the Farm Boon,” by Timothy Wise at the Tufts University Global Development and Environment Institute. In a tidy and digestible five or six pages, Dr. Wise debunks the common narrative that historically high crop prices have improved the economic situation for most American farmers.

First, you have to understand that crop prices are high—in some cases (such as corn), really high. A recent check shows corn is trading somewhere around $6.20/bushel, down from recent highs but several times the price guaranteed by the government. As a result, farm revenues are up—farmers are taking in more money for the crops they sell.

The USDA, among others, has trumpeted the “highest net farm income since the nineteen seventies.” Unfortunately, things aren’t so good for Farmer Joe. As Wise asserts, most of the reports making such claims suffer from a critical flaw: they include information on all individuals whose property is classified as farmland by the government. In fact, most (about 2/3) of these “farms” do not produce much of anything at all; they are used as tax shelters (usually to reduce the property tax burden).

This distinction is fundamental if we are to understand the socioeconomic plight of the farmers that produce the bulk of our food. I cannot tell you how many reports I have read that fail to make this distinction, including (as Wise points out) most of information coming out of USDA through ERS and ARS.

Suffice it to say that real, net income for most farmers has dropped over the past decade even as prices have soared, although the same cannot be said for huge farms selling $500k or millions of dollars in product each year. The reason for falling incomes? Input prices have soared even higher: fertilizer, pesticides and, of course, the price of oil.

Misleading statistics are used for all kinds of political objectives. In the case of agriculture, they are often used to paint a nicer picture of the average US Farmer’s economic situation. But anyone who has ever looked at a chart of income distributions in farming knows that the mean (income, farm size, etc) is a horrible statistic to use to describe a distribution that is nothing near normal. A much better statistic, if you had to choose only ONE, would be the median. You can have the craziest distribution in the world, but if you know the median, you at least know that the number describes the point at which half the population is doing better and half worse.

Perhaps the most important takeaway from Wise’s piece is that farms are getting bigger in response to market pressures. Bigger, and increasingly dependent on the industrial inputs that sound the death knell for long-term ecological health. Large farms succeed [sic] because they do not pay the full price of their inputs; they do not pay the external costs of pesticide exposure, nutrient runoff, soil loss or even the full price of oil, subsidized as it is by American military force, a lack of climate change legislation, and greedy autocratic regimes with short shadows of the future.

Dr. Wise’s prescription is to continue direct subsidy payments for commodity producers, a prescription that Congress is not likely to fill when they re-write the Farm Bill this year or next. And it’s a good thing. Continuing direct subsidies is the worst kind of Band-Aid for a systemic infection that can only be solved with systemic reform. Rather than asking How can we keep mid-sized farmers afloat with government handouts? we should be asking how policy can level the playing field by making producers pay the full cost of their production.

Any such action would certainly raise the price of food. But remember, Americans spend a tiny percentage of income on food compared with other developed countries (and especially compared with developing ones). If we are concerned (and we should be) about the effects of food prices on poor people, we should strengthen the safety net of WIC and EBT. Depending on ever-larger corporations to grow cheap food using subsidized inputs points us in the wrong direction.

Oh, Deer

As children growing up in rural Chatham County, my sister and I competed to spot deer while our car sped along the ribbon of back-country roads. Most nights we pulled into our driveway disappointed. But occasionally the headlights would illuminate a bright pair of white eyes lingering on the forest edge and our mom would slow down so we might admire the sight, like tourists on African safari.

Driving along those same roads out to the Duke Campus Farm, it is nearly unthinkable to make it without seeing at least one herd of deer. Recent studies have shown that this change is not merely anecdotal. White-tail deer populations are ballooning and their numbers pose an environmental, moral and human health crisis.

Unfortunately, there are no silver bullets that will solve overpopulation. But there are bullets. It is time to reconsider our regional approach to the management of deer populations, including loosening restrictions on hunting and legalizing the sale of wild venison.

Calls for more hunting inevitably evoke the rancor of those who wish Bambi’s mom had returned home safely.  Yet opponents of deer hunting would do well to remember that hunting associations saved the white-tail deer after farmers had driven them to the brink of eradication.

In 1930 there were fewer than 300,000 deer east of the Mississippi River. Today, there are about two million in North Carolina alone, and as many as 80 deer per square mile in parts of the Triangle, about five times the sustainable number.

Deer overpopulations wreak havoc on forest ecosystems, especially the young pine forests so common in these parts. They eat shrubs, small plants and tree seedlings so voraciously that the Duke Forest has labeled them a major threat to local biodiversity.

In the absence of population control, deer will eat themselves into starvation. On a recent visit to the Duke Campus Farm, on the edge of the Duke Forest, I stumbled on a herd of seventeen deer.  They were not the full-bellied, vigorous deer of my childhood memories.  Having picked clean the forest floor, the emaciated deer had ventured onto the farm in search of food (explaining the 7.5 foot deer fence that protects our fragile acre).

Animal rights advocates are not doing the deer any favors in their blind opposition to hunting. Hunting restrictions have exacerbated the boom and bust cycles that lead to mass starvations. Meanwhile, population pressures have driven more deer out of the forest and into the crosshairs of unwary drivers.

A 2009 study out of UNC Chapel Hill estimates that deer are involved in over 17,000 automobile accidents each year in our state, or about 10% of all accidents. This represents a 25% increase since 2004.

Deer-vehicle collisions impose significant economic costs estimated at $127 million annually in NC. Worse still, no good comes of deer carcasses rotting in the grass or littering the shoulder of the highway. Moral outrage should not demand that deer are never killed. We should demand that deer are killed humanely and not wasted.

Several local programs are working to bring sensibility back to deer population management. In a highly controversial program, The Duke Forest has allowed bow hunters to take as many as 200 deer a year since 2006.

In years past hunters shared half of this venison with local food shelters. Last year, in another ominous sign that populations are wildly out of control, many deer taken during the annual hunt in the Duke Forest were too sickly to be eaten.

That’s why we need an enlightened public policy that allows enough hunting to create a perennial equilibrium where deer can thrive without exploding in sheer number. Smaller populations will be healthier, happier and less destructive to habitat and automobiles.

Legalizing the sale of wild venison is an important first step. Venison is a tasty, sustainable and local source of meat. We served both venison stew and venison tacos at our Fall Farm Festival last October (to mostly rave reviews). Creating a market for local venison would promote a less wasteful approach to hunting and would allow officials to regulate safety and quality standards.

As a community, we need to summon the courage to embrace hunting as a responsible and necessary approach to deer control. It is time to swallow our medicine and allow hunters to bring deer populations back into a healthy equilibrium. If we’re lucky, we might get to swallow some fresh venison, too.

Paradigm Shifting Down on the Farm

Of all the trends in American agriculture, I want you to consider two for a minute.

First, the American farmer is aging: the average farmer was just over 50 in 1978, 54 in 1997, and is about to turn 58. New farmers are not replacing their aging predecessors nearly fast enough to keep up. The U.S. needs a new generation of farmers to pick up the plow as half of all American farmers retire in the next decade.

Second, the American farm is growing. The acre-weighted median farm (feel free to email me if you want a complete description of how this statistic is calculated) has grown 35% since 1982, meaning most agricultural production occurs on farms bigger than 2,000 acres. Large farms overwhelmingly use capital and input-intensive processes focused on growing commodity crop monocultures with myriad environmental externalities.

To summarize, we have a lot of older folks growing crops in increasingly unsustainable ways. Why isn’t grandpa’s generation leaping into the sustainable food movement, even though organic demand continues to outstrip supply?

Well, older farmers tend to be set in their ways, even, dare I say, stubborn. They are less connected to digital social and knowledge networks where they could learn about new sustainable practices; as one farmer told me, “We older farmers are somewhat allergic to the internet.” And older farmers are less willing to make investments that would enhance their land over time (preferring instead to save for retirement, or take a vacation). And I won’t even get into Farm Bill policies, which have made land-pillaging practices nicely profitable.

Wait, wait, I know we’re off to a depressing start. American farmers are old, unsustainable and unwilling to change. Bummer. But they’re also old. Or as Thomas Kuhn put it: “Conversions will occur a few at a time until, after the last hold-outs have died, the whole…will again be practicing under a single, but now different, paradigm.” Not so subtle, Dr. Kuhn, but maybe pretty wise.

To rephrase, the dinosaurs of conventional agriculture won’t be around forever. If they eat the same food [sic] they’re supplying the rest of the country, they won’t be around long at all. Which means it’s up to my generation to restore sanity, care and justice in our food system. Returning to Kuhn, who was a rather brilliant man when it came to revolutions: “Almost always the men [sic] who achieve these fundamental inventions of a new paradigm have been either very young or very new to the field whose paradigm they change.” Pun intended, by the way. Go ahead and have a second look.

Anyway, the question becomes, what do we “very young” and “very new” busy ourselves with in the meantime? How can my generation prepare for a paradigm shift in agriculture when land is so expensive and we are so very poor?

It’s a question with a complex answer, but seeing as this is a “policy blog” I want to highlight one policy that will help. The “Beginning Farmer and Rancher Opportunities Act of 2011” is a bill that is currently sitting around on Capitol Hill doing whatever it is that bills do while they wait to get passed (or, more likely, as they wait to die).

There’s no need to get into the specifics on “BFROA” (as we in the know call it)—other much smarter people have carefully explained the bill’s particulars—but I will say that this bill takes one very small step toward overcoming the barriers that keep small, young, sustainable farmers out of farming. New farmers need land, they need loans, and they need a marketplace that pays a fair price for their food. At the very least, this bill would throw a handful of (organic) fertilizer onto the beginning farmer movement to help it grow a little stronger. If you think that’s a good idea, give a holler to your congressman.

What does “sustainable ag” mean to you?

Last month the Carolina Farm Stewardship Association hosted its annual Sustainable Agriculture conference in Durham, and a handful of Dukies donned our best plaid shirts and headed down to the Imperial Sheraton to see what was going on. The conference attracts goers from all over North and South Carolina who are interested in “sustainable” food and agriculture (more on that in a minute). Everyone from farmers young and old, food processors, catering companies, academics, equipment suppliers, policy wonks and activists huddle in small conference rooms to discuss a dizzying array of topics. Want to learn how to build a greenhouse? There’s a demonstration. Want to know how cover crops fix nitrogen? A lecture from an expert from NC State. Want to make meade? Butcher your pigs? Write a business plan? Plant your crops based on the phases of the moon? Check, check, check, and, well, check.

It is this diversity of topics, interests and individuals that makes the conference so enriching and why I will surely be back next year. But it is important to remember that this convivial, excited atmosphere comes at a price. The word “sustainable” has become a buzzword appropriated by anyone to mean anything, and CFSA applies it masterfully in this sense. To some, sustainable means locally produced; but 10 miles? 50 miles? Within NC? To others, it means organic growing practices; but certified organic? Free from any chemicals, even natural ones? To others, it means capable of continuing in the wake of Peak Oil; but, is biodiesel okay? Can I use my horse carriage to transport food if I didn’t build the carriage myself? To yet others it takes on financial meaning; but financially sustainable by whose metric?

Of the more than 1200 people who attended, I can guarantee that no two people would define sustainable agriculture—or its parent, “sustainable food system”–in precisely the same way. There are farmers who believe that they are sustainable simply because they make a profit. There are others who won’t be satisfied until we are all growing most of our own food in the backyard. And there is every shade in between.

This is not a critique of CFSA—casting a huge umbrella enables the kind of discourse about food and agriculture that this country desperately needs. And to the extent that we can all say “This is what sustainable means to me, and this is what sustainable is not”, the better our society can hash out the tradeoffs we make with our policies and pocketbooks.

I encourage everyone who attented the conference, and anyone interested in food and agriculture, to spend some time defining “sustainable agriculture” and “sustainable food system” for themselves. Write down your definition, write down your reasons, and share it with a friend. Or if you’re feeling bold, post it here and let’s compare notes. Then we can go about the real work of changing the world.

What’s Wrong with ACRE?

Now that the specter of the Super Congress has passed, and with it the cloak room deals that would have comprised the next farm bill, we can all enjoy a winter respite and the chance to learn about farm policy before the process gets underway again early next year. A month ago I would have rung in the holiday season with a more tantalizing topic–conservation programs, crop insurance boondoggles, or the role of the carrot in 17th Century Dutch revolutions–but that will simply have to wait until December. Instead, it’s time to learn about so-called “shallow loss” revenue protection programs.

Why? Because that’s what Big Ag is shoving down Congress’ throat. It’s what the Ag Committees are hearing that farmers want. And it’s bad for sustainable farmers and the American people. To prove the point, we’re going to look at the 2008 Farm Bill’s version of shallow loss protection, the ACRE program (this horrible backronym stands for “Average Crop Revenue Election”…it’s intractable name is symbolic of the program I’m about to describe).

ACRE (Somewhat) Demystified
ACRE originated in the 2008 Farm Bill as both a compliment to and a substitute for pre-exiting subsidy programs. The mechanics of the program are complicated (and, as a result, many fewer farmers have signed up than originally anticipated). The implications of the program are complex and not yet well-understood (and, as a result, many of us sustainable farmers have not taken a strong position either way).

Program Mechanics
At first glance, ACRE appears to have been devised by a madman. There are something like 36 separate calculations necessary to determine if a farmer is entitled to a payment and, if so, how much. The first thing to know is that the program, like other federal subsidies, targets producers of commodity crops. In order to qualify a producer must have the same type of base acreage (historical production of commodity crops) that is used to calculate direct subsidy payments. A farmer may choose to keep his/her current suite of subsidy programs, or may opt into ACRE, thereby sacrificing 20% of direct payments, 30% of his/her marketing loan rate, and 100% of counter-cyclical payments (all major subsidies).

In exchange a farmer is eligible for a payment that depends on the magnitude of the discrepancy between the guaranteed and actual state revenue, and on the relative productiveness of the individual farmer compared to the state average.

Program Implication
According to the Farmland Trust of America, “The Average Crop Revenue Election program is a first step towards fundamentally reforming subsidy programs to be more market oriented with fewer incentives to overproduce.” This is probably true, with special emphasis on “first step”. Price-based subsidies distort the market in particularly insidious ways for conservation. By (artificially) raising prices, producers have the incentive to produce more and converting marginal or virgin land into intensively-cultivated commodity acres.

ACRE treats one a particular type of risk very well: the risk of falling commodity prices from very high levels. Agricultural economists suggest that high prices in the 1970s led to the farm crisis in the 1980s as prices fell. ACRE is designed to prevent such a recurrence. It goes like this: high crop prices increase demand for farm inputs as farmers scramble to get more acres under production. Input prices rise in response, and thus total costs of production rise. When market prices are very high, as they have been in the past several years, the risk is that prices may tumble well below current levels but still not trigger payments that are tied to a price floor. Even if lower prices only prevail for a year or two, the ratio of revenues to costs can be enough to put many farms out of business. ACRE provides a short-term bridge to help farmers maintain their income during these declines. However, unlike price floors, the moving average nature of the revenue guarantee ensures that ACRE doesn’t become a long-term price support. If market prices remain low, farmers retain the incentive to adjust their operations and produce what the market demands (as reflected by prices).

So, why is ACRE bad news for farmers whose farms look more like the Duke Campus Farm than like the square-mile commodity corn fields? Because farms aren’t eligible if they’re not growing commodity crops. Growing vegetables? You’re outta luck. There is nothing outwardly abhorrent about a system that protects farmers from catastrophic price changes for the crops they grow. What’s disgusting is a system that has so over-commoditized food that it is traded like iron ore or treasury notes on international futures markets. When farmers grow food that people want to eat–especially when those people are their neighbors–price collapses don’t happen.

Many of us know about and love “community supported agriculture” (CSAs). In CSAs, consumers pay the farm up front and receive a share of the farm’s bounty for the season. In good seasons, the consumer gets an abundance of produce. In bad seasons, their weekly produce box looks pretty scant. This is nothing less than a local, sustainable form of shallow loss revenue insurance, one that doesn’t distort markets, incentivize unhealthy food, or bankrupt the government. This is the kind of insurance that we, and our government, should find ways to support.

Let’s Talk About…Ag Policy

ATTN: Calling all foodies, policy wonks and friends of the earth.

I want to invite you to join me on a journey through the wild and whacky world of American agricultural policy.

If you’re reading this at all, you’ve probably already got some opinions on our country’s ag policies. A lot of us in the foodie and sustainability worlds walk around like zombies muttering well-worn mantras.

Crop subsidies…BAAAAD. Slow food…Goooood!

Corn ethanol, bad. Farmers markets, good!

CAFOs, baaaad. Michael Pollan, good (and delicious!)!

Sound familiar?

In this blog, we’re going to dig into the meat of these issues. I’m not going to try and disavow you of your opinion that subsidies are bad or that Michael Pollan is a foodie god. I quite agree. But what happens when you want to go beyond the mantras? When selling a skeptic on the rightness or righteousness of sustainable food production depends on a somewhat more nuanced understanding?

There is a great scene in Season 4 of the West Wing. President Bartlet is engaged in a fierce battle with the Republican nominee, a former governor from Florida. The nominee is full of the small government bluster and bravado that seems all too prescient at the moment. In their only debate, the moderator asks the Governor whether tax cuts are really the right solution to the country’s economic woes:

Governor Ritchie: You bet it is. We need to cut taxes for one reason – the American people know how to spend their money better than the federal government does. 

Moderator: Mr. President, your rebuttal.

President Bartlet: That’s the ten-word answer my staff’s been looking for for two weeks. There it is. Ten-word answers can kill you in political campaigns. They’re the tip of the sword. Here’s my question: What are the next ten words of your answer? Your taxes are too high? So are mine. Give me the next ten words. How are we going to do it? Give me ten after that, I’ll drop out of the race right now. Every once in a while… every once in a while, there’s a day with an absolute right and an absolute wrong, but those days almost always include body counts. Other than that, there aren’t very many un-nuanced moments in leading a country that’s way too big for ten words.

This blog is for those who believe in the ideals of sustainable agriculture but whom also recognize that ten words are not enough. Transforming our agricultural system—or even nudging it in the right direction—will require more than ten words. This country badly needs a new paradigm of agriculture, what Wendell Berry might call a rediscovery of the “Agrarian Standard.” But before that’s a possibility, we need an army of people who are passionate, committed and informed about the complexities involved. We need evangelists wielding hard facts.

So, yes, we’re going to talk Title II of the Farm Bill (the Conservation Title). And we’re going to learn about the “disappearing agricultural middle.” And we’re going to talk crop subsidies—direct subsidies, counter-cyclical payments, crop loan guarantee programs, and the Average Crop Revenue Election (ACRE) program. And, yes, we’re even going to delve into crop insurance (perhaps the largest and most pernicious government subsidy of all, it turns out).

My goals are pretty simple. First, to provide a readable (and dare I say entertaining?) overview of the policies that are (in my opinion) doing the most harm or good for sustainable agriculture. But this is the Duke Farm blog, and I have a second goal: to ground these wonkish musing in the very real work we are doing at the Duke Farm.

Much of what is wrong with American Agriculture is its abject failure in supporting small, sustainable farms like the Duke Campus Farm. In fact, most sustainable farmers will tell you that if the government weren’t doing anything, that would be just fine. In fact, our national policies are hurting precisely the types of farmers that grow healthy foods in sustainable ways. The Duke Farm will provide our window of understanding into just why that is.

I hope you’ll read on as I get started on this project. Please don’t hesitate to join the discussion or to suggest topics that you would like to hear more about.
