Chickens for Poor People, Part 2

Aimee, a fellow blogger who writes New To Farm Life, made another insightful and informative comment on my post, “Chickens for Poor People.” She said,

I mean, it [the tendency I spoke about to make chicken-keeping and other acts of self-reliance more complicated than necessary] might be another symptom of the same disease that causes helicopter parenting - an overwhelming anxiety that things will go to pieces if you aren't in total control of all variables at all times.

“I'd like to recommend Storey's guide to chickens (they have a whole series on farming). These guides are down to earth and relaxed, providing information but with a general attitude that even children can successfully raise animals of all types. Storey's chicken book has plenty of plans for simple chicken houses, too.

“My chickens roost in the rafters of the barn. Most breeds of chicken will do fine with a roof, a good windbreak, clean water and ample food. They need a few square feet apiece, minimum, to stretch and scratch. Chickens will be extra happy if they can also make wallows and take dirtbaths.”

That sounds like good advice. I'll have to find Storey's book when I get a chance. And it's helpful to realize that chickens, being birds after all, are quite able to survive without human intervention. (Otherwise, there'd be none on earth today!)

On another note, posting will be light over the next week (and maybe two). I've got a ton of homework to grade and I need to catch up.

"Path to Freedom" On Probation

It came to my attention recently that "Path to Freedom," the urban homesteading project of Jules Dervaes and his family, has made some enemies in the urban homesteading/self-reliance/collapse preparedness communities. It seems that the Dervaes family has submitted for trademark registration several phrases commonly used by writers, thinkers, educators and other activists in the preparedness community. Not only have these phrases been registered as trademarks owned by the Dervaes family, but according to at least one source, the Dervaes family has begun sending cease and desist letters to Internet writers who use these phrases, as well as local volunteer urban food gardening teachers.

If these things are true, it would be a big disappointment - yet it would not be entirely unexpected. Many of those who are interested in urban farming and simple living are trying to escape a dominant, predatory economic system. It makes sense that those who rule that system would try to block the exits - or, perversely, try to charge escapees some sort of fee in order to use the exits. In my mind, Jules Dervaes and his family used to stand as a model for people who are trying to escape from a dominant, exploitative system into a more equitable way of life. Now it seems they are trying to cash in on the system they claim to be rejecting. One may as well try to collect rent from people who watch the sunrise. If that's what Jules Dervaes and his family are up to, it's unethical and immoral.

It may also cost him big time. I have written him an e-mail asking him about these things. If I don't hear back from the "Dervaes Institute" within a week, or if I don't like the answer I do get from them, I will remove all links to "Path to Freedom" from my blogs. I am sure there are many other bloggers who are of the same mind. But if on the other hand, we have all misunderstood the Dervaes family, it may cost some of us - in terms of humiliation, egg on our faces, sheepish apologies, admissions that we misunderstood some really decent people and let ourselves be swayed by rumors blown out of proportion. I really hope that it's the latter. I'll know in a week.

A Fight In The Outhouse

I've said many things over the many posts of my blog. Some of them have been things that I knew right at the outset to be inflammatory. I didn't think a post on recycling human waste for agriculture would raise a stink, but I guess I was wrong. Some of the responses to my last post have been surprising.

There's one blogger whom I suspect of thinking that I've turned into some sort of techno-optimist who believes that technology can solve all our problems. To him I would say "no worries" – I haven't turned into a collapse “heretic.” Rather, I hold the premise that our current method of farming is unsustainable, and that one big reason for this is our way of disposing of human waste. Therefore we have to begin “closing the loop” by finding ways of recycling human waste so that it can be returned to the soil. My interview last week was an attempt to see how many people in the local government of the city in which I live realize this, and how deeply they realize this. I personally think that Portland could go much farther in recycling human waste, and that all cities in the U.S. will have to do things differently fairly soon. But when I interview people, I generally don't try to beat them up – it's considered to be in poor taste. (I might make an exception for certain rich people and media figures – so Rupert Murdoch or Glenn Beck might want to avoid having me interview them.)

What's been more interesting are the comments a couple of people sent me, warning me that sewage sludge and biosolids are the same thing, and that sewage sludge is a dangerous pollutant that should never be applied to agricultural land. One of these commenters writes that “biosolids” is a term coined by the sewage “industry” in order to market a toxic product which has endangered many people. Another commenter states that “according to the Federal Clean Water Act, biosolids/sewage sludge is a pollutant.” Reading through these comments, however, gives me an impression of people who are impassioned in their opposition to use of biosolids, yet who have not carefully read my post or the references I cited at the end, nor listened to the podcast to which I linked.

Now I just want to say that I try to keep an open mind about many things. But I try not to post allegations about things or people unless I have very good corroborating sources to back the allegations. To do otherwise in this case would not be fair to the people I interviewed. I am happy to post further comments on the subject of recycling human waste. But let's lay down a few conditions first.

If anyone wants to comment on my post, “Sewage Recycling - A Loop Almost Closed”, please read it first – the whole thing. Then read the supporting references and listen to the podcast. If after that you still believe that biosolids are unsafe for agriculture, please provide information which refutes each point made in the post and in the accompanying references. If you don't have time for all of that, at least read some of the EPA references I cited, along with Greg Charr's PowerPoint presentation, and provide documented information that refutes at least two of the statements contained in those references.

Lastly, if you believe that biosolids should not be used for agriculture, please present your own solution to the problem of soil depletion caused by modern industrial agriculture and modern sewage removal systems. That, after all, is the whole point of this discussion. Flushing humanure down toilets and into our oceans is depleting our soils, and this will lead sooner or later to agricultural collapse. What do you think we should do about it?

If you will answer these questions, that will let me know that you have read all of what I said in my post. And if you will especially answer the last question, that will let me know where you're coming from. If you will do this for me, I will post your comments – even if I don't agree with them. If you don't do these things, I will not post your comments.

Threatened Honeybees and Urban Sanctuaries

On the 20th of March, I attended a beekeeping workshop at Zenger Farm in Southeast Portland. The class was taught by Tom Lea, one of the founders of Zenger Farm's Community Bee Group.

The workshop was a good introduction to the practice of urban beekeeping as an element of “home economics,” or the set of skills by which households can meet their own needs. There were also a couple of facts mentioned that have a huge bearing on agriculture in general and the relationship of Americans to the food they eat. First, it was said that a majority of Americans kept bees from the time of the Revolution until just after World War Two. Beekeeping was an art handed down through the oral transmission of “bee lore” and through apprenticeship. Then modern industrial factory farming arose and wiped out the large-scale practice of keeping bees, as people traded their skills for the convenience of the supermarket. Only in recent years, as the weaknesses of the industrial food system have become widely reported, have people begun to revive their interest in things like beekeeping.

And that brings up the second point. Mr. Lea mentioned the threat of colony collapse syndrome, and placed the blame for this syndrome squarely on the large-scale agribusiness practice of shipping bees hundreds to thousands of miles each year to pollinate crops at various farms. (This is also mentioned in a Wikipedia article that describes the practice of “migratory beekeeping” and the fact that it artificially boosts crop production on farms.) In his words,

When you're dealing with smaller scale agriculture, you don't have the pests that you have with agribusiness, because you don't travel as much. With beekeeping, the bees are being transferred down to, for instance, orchards in California for almond pollination, and all the diseases are transferred from one hive to another, and then they're taken back to their homes. So diseases are spread around like nobody's business...But this [colony collapse] is just the canary in the coal mine. All agribusiness is like this; everything is moved around much more, and on such a large scale that the pests, viruses, diseases and stress that we see in honeybees are now being experienced in every area of agriculture.

It's not something that can go on forever. At some point, different areas of agriculture will collapse as we are seeing with honeybees. It's a perfect storm... [Emphasis added]

In other words, the very practices of industrial agribusiness generate consequences that threaten the very existence of industrial agribusiness. And colony collapse, along with the rapid spread of plant and animal disease, are consequences of large-scale, fossil fuel-driven industrial agriculture and the transport of plants, animals and insects over thousands of miles.

Mr. Lea held out hope that small-scale agricultural practitioners can provide a defense and remedy for the dangers posed by industrial agribusiness. Toward that end, his workshop offered a number of resources for people who want to get into urban beekeeping. Some of these are:

I also made a video of excerpts from the workshop. You can watch it on YouTube at this address.

Leaving the Cubicle for the Farm (In The City), Part 2

This post is part 2 of a transcript of an interview I did three weeks ago with Josh Volk, urban farming consultant and proprietor of Slow Hand Farm. Part 1 can be found here. For the sake of continuity, I have included all of Part 1 as part of today's post.

Speaking of Part 1, I noticed that after I published that post, the Energy Bulletin website started churning out articles covering many of the same things discussed in my post, including the idea of cities putting together “diggable databases” of urban plots available for cultivation as the city of Portland has done. I'm glad I could be something of a ghostwriting inspiration to the folks at Energy Bulletin. (Then again, thievery is a form of flattery, isn't it?)

And now for Part 2. As usual, my questions and comments are in bold type.

What are the first steps for someone who wants to transition into urban farming as a career?

The first thing is to ask what your goals are. In other words, why are you doing this? What do you want to be doing day by day? Second, ask yourself what you need to get out of it, both financially and otherwise. Lastly, there is learning the skills. This depends heavily on how much money and space you have to play with.

When I first started, I met with this guy named Jac Smit, and he had an organization called the Urban Agriculture Network, which I think is still going – he died last year – but he had been working on urban agriculture projects. It turned out that he was not working on things in the United States – there really wasn't much going on in the United States at the time, but in a lot of other countries, they were fairly far along, particularly in a lot of developing countries, partly out of necessity.

He said one of the problems he saw in the United States was that most of the people that were interested in urban agriculture came from an urban background and probably came from a gardening background. They didn't know a whole lot about production, and didn't have the same mindset or skill set as a farmer who is producing goods. They were just growing things for their own consumption. So he said, “If you're really interested in urban agriculture, you should go and you should learn farming – and then bring that back into the urban setting,” because it's an appropriate thing, and that was one of the things that he saw that was working in developing countries – a lot of the people coming into cities were very recent migrants and had an agricultural background already.

So I took that advice and I went and apprenticed on a farm. And I've kind of been stuck in that farming thing for more than ten years now, learning the production end, and I feel like I'm just starting to get back to it [urban farming]. In some ways I'm actually a little less excited about it now, because I know some more of the realities and some of the reasons why it doesn't work as well. But I haven't given up on it, so I'm still looking at it and trying to figure out how I think it fits in best.

It's been about fifteen years since I talked to Jac Smit, and I think in that time period, the landscape has changed a lot, and there are a lot more people who are looking at urban farming, and there are more people coming in and doing urban agriculture projects with a production background, but there are still a lot of people doing it without that background. So that's one place where you could start – go to some production farms, whether in the city or outside the city, and just learn the techniques they're using and try to apply that to a smaller scale.

What were some of the difficulties you encountered that made you less enthusiastic as time passed?

One thing is that I'm excited about growing a lot of different things. If you are trying to do production in an urban environment, land is very expensive – space is very expensive – and water is expensive. There's a very limited subset of crops, I think, that make sense for a limited space. There's a lot of crops that take up a lot of space, so there are some things where I'm not sure how they fit into the urban setting, and I wasn't aware before that there were those differences, or maybe how big those differences were.

For example, the urban agriculture projects that I've seen that have been the most successful generally concentrate on something like salad greens, because you can grow a lot of salad greens in a very small space. And people don't eat as much by pound of salad greens as they eat of something like wheat. In 100 square feet you might be able to get a couple hundred servings of salad greens, whereas with wheat you could get something on the order of ten servings. That's a big difference, and the price of salad greens is probably at least five if not ten or twenty times as high as the price of wheat. So when you think about what you're going to do with an expensive, limited amount of space, there are some limitations there.

What does it take to get access to land in the city? Say Portland, for example?

There's a bunch of different models I see. Some people just outright buy a spot and own it. I have friends who just bought a house that sits on six tenths of an acre. I don't think there's a lot of places like that left in Portland, but there are still places like that. If they really wanted to push it, as a couple, they could certainly make a living off that amount of space. Other people might have a small yard of their own or they might have multiple small yards, and they're bartering that space, either because the people want to see things grown on it, or they want a share of the produce coming from it. And that's questionably legal right now, although the zoning will probably change in the near future to make it legal.

Why is it not quite legal right now?

It's questionable whether the zoning allows you to grow something and sell it on your property. You can probably argue that you can grow it and sell it, but the way that you sell it would have to be off the property. So if you were trying to distribute it directly on the property, that would probably make it illegal. It could probably be argued – although I'm not sure anyone would do this – that it's not even really legal to grow it on your property. Certainly if your neighbors were complaining, they would have a case, although they would probably not win, advocating that you shouldn't be doing what you're doing.

That you shouldn't be growing things on your property?

Not that you shouldn't be growing things, but that you shouldn't be growing them commercially. It's the commercial designation that makes it legal or not legal, because the space is zoned residential; it's not zoned commercial or agricultural. The same thing goes for commercial spaces, because they're zoned for a particular type of commercial use and they're not zoned for agriculture. Contamination is another issue you have to look at, because there are a lot of contaminated soils in urban areas and concentrations of different kinds of chemicals, particularly lead paint.

So another way people get land is more temporary – but land owned by a developer or even publicly owned land has a designated use, yet isn't going to be put to that use for a few years. So the owners may allow that land to be used for a period of time to grow things until they're ready to build their project on the land. I know a few people who are farming on such land; one group in North Portland is doing that with a church property where the church is going to expand, but they're probably not going to do it for another four or five years, so in the interim they're letting folks grow crops on the land.

And the County has a certain amount of tax-foreclosed land, and they make some of that available to organizations that want to do urban agriculture projects. Typically, these are non-profit – but a food production “business” (for lack of a better word) wouldn't necessarily have to be for profit; you could run it in some sense as a non-profit, and in an urban setting, that might actually make more sense, especially as you're not likely to make much of a profit anyway.

How do you find this land? Do you go on real estate websites to find properties like this that people aren't intending to use for a while?

I think one of the things that's an important distinction between urban agriculture and other types of agriculture is that there's a community aspect to it, and I think networking is important. Networking is how those lands and spaces get identified. It's probably more word-of-mouth than anything else. Once you get connected into a community of people that are talking about that and you start putting it out there that you're looking for space or that you have a project you want to do, you start running into people that say, “Oh, I know a spot. You can check with this person,...” or, “I have a spot. How could we work something out?” That's what makes urban agriculture work in a way that rural agriculture isn't working right now.

I think there probably are efforts – I can't recall any off the top of my head – but I think there are people who want to make clearing houses and create lists of available land. There was an effort through the City – I'm forgetting the name – I think it was the “Diggable City” project that tried to identify land a few years ago. But as far as the people I know who are actually doing urban agriculture projects, it's been more word-of-mouth, or people finding each other through existing networks.

You say that rural agriculture is not working that way – is rural agriculture failing in the United States?

In general, I think that it is, because I think what's happened is that the consolidation that's happened in terms of family-scale farms being consolidated into larger and larger industrial corporate factory farms has torn apart the rural community. So there's not a whole lot of “community” in rural communities anymore. That's a big issue, because it has switched the population base in the U.S. from a rural one to an urban population. This has gutted rural communities. It has also disconnected rural communities from urban markets – it has put a couple more layers of distribution systems between the two, because consolidation makes those operations so large that they have to distribute over a wider area in order to make their business work. That has lengthened ties and broken ties in a lot of communities.

If I were to look at the whole picture, I would say that strengthening the rural communities and going back to a rural agriculture that makes more sense is in most ways more important than thinking about how to do urban agriculture appropriately – because there is land there, and it's inexpensive land. If instead of trying to concentrate everybody into a few large urban centers, and figuring out how to make that urban land produce intensively for those people, we could spread those people out more so that the resulting population centers had more of a land base and didn't have to work so intensively, I think that would be ecologically a better model.

Let's say someone decides they want to move out to a rural area. They look on “Oregon Lands for Sale” and see a nice property, and they say, “Let's go for it, babe,” and they move out there. What are the financial barriers and pitfalls that might drive them back into the city? I know that you're not going to get rich from farming...

I don't think it's impossible to get rich, but I think you have to be more of a businessperson than just an idealist. You'd really have to concentrate on what it is that you're growing and how you're doing it, and take advantage of the things that a lot of other kinds of businesses take advantage of in order to make the people who own the business wealthy.

To get back to the pitfalls of moving out to a rural place, one is that there is still a general movement – although it's slowing down – toward consolidation in agriculture, and a movement from rural areas to the cities. So finding rural areas where that's not the case so much and trying to start a reversal – that's one challenge, or trying to become part of a movement that is reversing that trend in the particular area that you're moving to. To me that's a really difficult thing to predict – you can try to move to a place and become part of the community there, but it's a bit of a gamble.

I know farming folks, for example, who live on the south coast of Oregon, and they've lived there for their entire lives, and just now those communities are starting to grow again. They've been on a large downward slide for a long time, and now it's starting to come around again to where they have markets that they didn't have before for their produce. Before, they were more focused on exporting stuff and figuring out how to get it to the urban centers, and now they can actually market their goods within the area because of the change in the community.

How does someone secure land without going into debt, or without going deeply into debt? Or is that impossible right now?

I don't know if it's impossible right now – there's actually a blog by a guy named Andy Griffin, and he writes this blog called The Ladybug Letter. The writing is excellent; he doesn't post very often, but when he posts essays, they're really good. One of the last posts that he made was about that question. He's been farming in the Salinas area of California, which is some of the most expensive agricultural land in the country. He doesn't own any of his land.

He frames his essay in the form of a letter to these folks he heard on the radio. So he hears a young business student interviewed on the radio, and this business student is coming out college at a time when the economy is as bad as it's ever been in this person's lifetime. And the interviewer is asking this person how this is going to affect what the person will do once he gets out of business school, and he answers that he has a backup plan – “find some land with a bunch of friends and start a farm.”

So Andy's essay is his advice to this person, and the advice is, “Don't buy land.” There are enough people out there who own land and want something grown on it and are willing to lease it. From a business point of view, it's better to have the flexibility to leave the land if it's not productive in the way that you want it to be productive, and it's less expensive to lease the land than to buy it, and to get all your capital tied up in the land. You need your capital to be available for the operation of your business. His advice – and I think that in a lot of situations, it's very good advice – is to look for other options besides buying.

Try to find good long-term lease situations on good land, but leave things flexible, particularly if you're growing annual crops. It's more difficult to be flexible when you're growing perennials and tree crops. But with annuals, although this is not ideal, you can spend a year or two getting the land into good enough shape to produce profitably, and then pay off your lease in two or three years of crop production. And if the lease terms go longer than that, you're basically just making money. If the terms don't go longer, you haven't lost any money. But if you buy the land, you could get two or three years into working it and realize that the land doesn't produce what you want it to produce, and you'd be stuck with this piece that you have to keep putting excess money into.

Both from a rural and an urban standpoint, is it possible for a person without debts to pay the yearly expenses of life in the United States by farming?

Oh, sure, yeah! But part of it also goes back to that question of “What do you want to be doing from day to day?”, and “What do you want to be growing?” Is it possible in every situation everywhere? No, but farming isn't inherently not profitable. But there are certain segments of farming and ways of farming which are not profitable, yet common.

Ways of farming that are both common and unprofitable...how do they survive?

Well, most of them survive through subsidies. And there are all kinds of subsidies – some people subsidize themselves through holding other jobs, and some people are subsidized through the government.

But they're basically doing something that's unsustainable in the long run?

Economically, yeah, unless the subsidies stay there.

That brings up this question: a lot of Western farming is basically mining the soil. How do we “close the loop”? I read The Humanure Handbook and other literature along that line, and it seems like that's what we'll have to go back to if this is going to be viable. And there are podcasts on Deconstructing Dinner where they talk about decreasing concentrations of certain minerals in crops. So how do we close the loop? Is anyone working on that?

I think lots of people are working on it. It's a difficult question – are you familiar with biodynamic farming? Do you know who Rudolf Steiner is?

No...

Rudolf Steiner was a guy who worked on a lot of different things. He was able to understand the complete picture regarding many things. He worked on biodynamic agriculture. One of its primary tenets is that you create the farm as a closed system. He says something important when he says that this is the goal; it's not necessarily something that's going to happen. But if your goal is to always try to work toward the farm as a closed system in itself, so that nutrients aren't leaving the system and you're not having to import nutrients, you'll be creating a better form of agriculture.

So the whole biodynamic community is working on that. There are also a lot of people outside the biodynamic community – in organic agriculture, in particular – that have that same thought process. The people who are trying to do this properly who are at the same time trying to sustain themselves economically are always balancing those two things, because our present economic system basically doesn't reward that in any way. Instead, it rewards the “mining” system.

That's maybe one of the drawbacks of leasing as opposed to owning land, although it's not an intrinsic drawback. But the tendency with leased land would be to take that mining approach, because you won't necessarily see any kind of payback [from restoring the soil] as opposed to working the land for a longer period of time.

The humanure concept is an important one – to understand that anything people eat that's going off the farm – if you're not capturing that waste and putting it back into the system, then it's a loss, basically. You can try to limit the losses in every other area, but if you don't address this loss, you can't recapture it without mining somewhere else to bring nutrients in.

Are there experiments in urban areas in the United States to try humanure composting for urban agriculture?

It's very controversial in organic systems, because, for example, in the Midwest – I can't remember whether it's Wisconsin or Minnesota – they've been pushing sewage sludge as a soil amendment in fields, because it's high in nutrients. But the problem with the municipal waste system – and I think there's some question of the amount of heavy metals in people's diets also – is that you're concentrating heavy metals and other contaminants into that waste. So not only are you getting nutrients onto the fields, but you're also contaminating the fields by using sludge. For those reasons, the organic community has decided that they will not allow any kind of sewage sludge in organic fields. Cleaning up the waste stream has to happen before this waste can be used on a large scale.

On a small scale, the fellow that wrote the Humanure Handbook has a good argument for it and I'm sure there are other people doing humanure composting, but because of all the points he makes in his book, I don't think very many people are willing to talk about it openly. I've met a couple of people who have admitted to trying that system, and I haven't heard of any downsides, but I haven't met a lot of people who admit to it.

* * *

That concludes the main part of my interview with Josh Volk. We talked a bit more afterward about how people can learn farming by visiting urban farms and volunteering to help (along with volunteer etiquette). We also talked about a typical day for an urban farmer (contrary to stereotype, not all farmers work from sunup to sundown, seven days a week), and discussed a few urban farmers in the Portland metro area who transport themselves and their cargo entirely by bicycle. (Obviously, this doesn't work for everyone in every situation.)

One last note: for several months now, urban agriculture has been very much on the radar screen of the mainstream media. Many news articles have focused on key individuals – “movers and shakers”, if you will – with lots of money and influence who are announcing plans to “save” dying cities in the U.S. through the promotion of urban agriculture. The interest, energy and vision of these people is often praised by the media (and by undiscerning members of the blogosphere) as a good thing, a key component of a national return to a more sustainable lifestyle.

I think such a view is totally mistaken. The beauty of urban agriculture and of other strategies of resilience now being adopted by ordinary people is that these offered a way for ordinary people to decouple from a predatory economic system so that these people wouldn't keep getting bled dry by that system. When the “big people” – the rich and influential – also “discovered” these opportunities, they saw them not as a way to live more sustainably, but as an opportunity to cash in by turning a public trend into a growth industry. Therefore, where cities like Detroit were places where people who wanted to decouple from the money economy could go to live simply, cheaply and debt free, Detroit has now been “discovered” by speculators with big plans to “do something good for the city” while making tons of money. Thus one avenue of escape from our predatory money economy has been destroyed. Ordinary people in Detroit are once again in danger of being sucked up into a system whose masters maximize profits by squeezing people to death.

What good is urban agriculture to ordinary people if it takes on all the characteristics of every other form of industrial, consolidated modern agribusiness? What good is it to be an urban farmer in Detroit or Cleveland if urban agriculture there is controlled and run by a handful of rich speculators who have swooped in and bought up all the land and you're just minimum-wage "hired help"? I commented somewhat on the disturbing activities of speculators in depressed areas of our country in two 2009 posts titled, “Is Community Resilience Possible At This Time?” and “Report From The Front Lines - 3-20-09.” More recently, a blogger named Ran Prieur also made the same observations on his blog.

Leaving the Cubicle for the Farm (In The City)

One of the greatest needs of First World society (particularly in the United States) over the next several decades is for a great reskilling, as wealth and concentrated supplies of energy and raw materials dwindle and occupations connected with an energy-intensive society become useless. Farming is a skill that many of us will have to re-learn as the energy required for modern industrial farming becomes unavailable. At present, fewer than two percent of Americans farm for a living. We may be forced to return to a society like that which existed in 1900, in which around 41 percent of Americans were employed in agriculture.

Urban farming is a unique subset of farming in general, and where I live, there is a vibrant community of urban farmers. Urban farming was also on my mind a few weeks ago, as my (now former) office was very slow and I had time on my hands to consider other options for making an honest living. (No worries, I am now working at a different firm.) Thus it was that I found myself calling Josh Volk, urban farming consultant and proprietor of Slow Hand Farm. We got together at Stumptown Coffee in downtown Portland for an exchange of advice about urban farming, and specifically what challenges a person would face in taking up urban farming as a livelihood. Although I recorded the interview, it was very noisy due to the presence of many people and the sound of coffee and espresso makers. Therefore, instead of a podcast, I have only provided a transcript, which I have included below. Today's post is part one of the interview. My questions and comments are in bold type.

What are the first steps for someone who wants to transition into urban farming as a career?

The first thing is to ask what your goals are. In other words, why are you doing this? What do you want to be doing day by day? Second, ask yourself what you need to get out of it, both financially and otherwise. Lastly, there is learning the skills. This depends heavily on how much money and space you have to play with.

When I first started, I met with this guy named Jac Smit, and he had an organization called the Urban Agriculture Network, which I think is still going – he died last year – but he had been working on urban agriculture projects. It turned out that he was not working on things in the United States – there really wasn't much going on in the United States at the time, but in a lot of other countries, they were fairly far along, particularly in a lot of developing countries, partly out of necessity.

He said one of the problems he saw in the United States was that most of the people that were interested in urban agriculture came from an urban background and probably came from a gardening background. They didn't know a whole lot about production, and didn't have the same mindset or skill set as a farmer who is producing goods. They were just growing things for their own consumption. So he said, “If you're really interested in urban agriculture, you should go and you should learn farming – and then bring that back into the urban setting,” because it's an appropriate thing, and that was one of the things that he saw that was working in developing countries – a lot of the people coming into cities were very recent migrants and had an agricultural background already.

So I took that advice and I went and apprenticed on a farm. And I've kind of been stuck in that farming thing for more than ten years now, learning the production end, and I feel like I'm just starting to get back to it [urban farming]. In some ways I'm actually a little less excited about it now, because I know some more of the realities and some of the reasons why it doesn't work as well. But I haven't given up on it, so I'm still looking at it and trying to figure out how I think it fits in best.

It's been about fifteen years since I talked to Jac Smit, and I think in that time period, the landscape has changed a lot, and there are a lot more people who are looking at urban farming, and there are more people coming in and doing urban agriculture projects with a production background, but there are still a lot of people doing it without that background. So that's one place where you could start – go to some production farms, whether in the city or outside the city, and just learn the techniques they're using and try to apply that to a smaller scale.

What were some of the difficulties you encountered that made you less enthusiastic as time passed?

One thing is that I'm excited about growing a lot of different things. If you are trying to do production in an urban environment, land is very expensive – space is very expensive – and water is expensive. There's a very limited subset of crops, I think, that make sense for a limited space. There's a lot of crops that take up a lot of space, so there are some things where I'm not sure how they fit into the urban setting, and I wasn't aware before that there were those differences, or maybe how big those differences were.

For example, the urban agriculture projects that I've seen that have been the most successful generally concentrate on something like salad greens, because you can grow a lot of salad greens in a very small space. And people don't eat as much by pound of salad greens as they eat of something like wheat. In 100 square feet you might be able to get a couple hundred servings of salad greens, whereas with wheat you could get something on the order of ten servings. That's a big difference, and the price of salad greens is probably at least five if not ten or twenty times as high as the price of wheat. So when you think about what you're going to do with an expensive, limited amount of space, there are some limitations there.

What does it take to get access to land in the city? Say Portland, for example?

There's a bunch of different models I see. Some people just outright buy a spot and own it. I have friends who just bought a house that sits on six tenths of an acre. I don't think there's a lot of places like that left in Portland, but there are still places like that. If they really wanted to push it, as a couple, they could certainly make a living off that amount of space. Other people might have a small yard of their own or they might have multiple small yards, and they're bartering that space, either because the people want to see things grown on it, or they want a share of the produce coming from it. And that's questionably legal right now, although the zoning will probably change in the near future to make it legal.

Why is it not quite legal right now?

It's questionable whether the zoning allows you to grow something and sell it on your property. You can probably argue that you can grow it and sell it, but the way that you sell it would have to be off the property. So if you were trying to distribute it directly on the property, that would probably make it illegal. It could probably be argued – although I'm not sure anyone would do this – that it's not even really legal to grow it on your property. Certainly if your neighbors were complaining, they would have a case, although they would probably not win, advocating that you shouldn't be doing what you're doing.

That you shouldn't be growing things on your property?

Not that you shouldn't be growing things, but that you shouldn't be growing them commercially. It's the commercial designation that makes it legal or not legal, because the space is zoned residential; it's not zoned commercial or agricultural. The same thing goes for commercial spaces, because they're zoned for a particular type of commercial use and they're not zoned for agriculture. Contamination is another issue you have to look at, because there are a lot of contaminated soils in urban areas and concentrations of different kinds of chemicals, particularly lead paint.

So another way people get land is more temporary – but land owned by a developer or even publicly owned land has a designated use, yet isn't going to be put to that use for a few years. So the owners may allow that land to be used for a period of time to grow things until they're ready to build their project on the land. I know a few people who are farming on such land; one group in North Portland is doing that with a church property where the church is going to expand, but they're probably not going to do it for another four or five years, so in the interim they're letting folks grow crops on the land.

And the County has a certain amount of tax-foreclosed land, and they make some of that available to organizations that want to do urban agriculture projects. Typically, these are non-profit – but a food production “business” (for lack of a better word) wouldn't necessarily have to be for profit; you could run it in some sense as a non-profit, and in an urban setting, that might actually make more sense, especially as you're not likely to make much of a profit anyway.

How do you find this land? Do you go on real estate websites to find properties like this that people aren't intending to use for a while?

I think one of the things that's an important distinction between urban agriculture and other types of agriculture is that there's a community aspect to it, and I think networking is important. Networking is how those lands and spaces get identified. It's probably more word-of-mouth than anything else. Once you get connected into a community of people that are talking about that and you start putting it out there that you're looking for space or that you have a project you want to do, you start running into people that say, “Oh, I know a spot. You can check with this person,...” or, “I have a spot. How could we work something out?” That's what makes urban agriculture work in a way that rural agriculture isn't working right now.

I think there probably are efforts – I can't recall any off the top of my head – but I think there are people who want to make clearing houses and create lists of available land. There was an effort through the City – I'm forgetting the name – I think it was the “Diggable City” project that tried to identify land a few years ago. But as far as the people I know who are actually doing urban agriculture projects, it's been more word-of-mouth, or people finding each other through existing networks.

You say that rural agriculture is not working that way – is rural agriculture failing in the United States?

In general, I think that it is, because I think what's happened is that the consolidation that's happened in terms of family-scale farms being consolidated into larger and larger industrial corporate factory farms has torn apart the rural community. So there's not a whole lot of “community” in rural communities anymore. That's a big issue, because it has switched the population base in the U.S. from a rural one to an urban population. This has gutted rural communities. It has also disconnected rural communities from urban markets – it has put a couple more layers of distribution systems between the two, because consolidation makes those operations so large that they have to distribute over a wider area in order to make their business work. That has lengthened ties and broken ties in a lot of communities.

If I were to look at the whole picture, I would say that strengthening the rural communities and going back to a rural agriculture that makes more sense is in most ways more important than thinking about how to do urban agriculture appropriately – because there is land there, and it's inexpensive land. If instead of trying to concentrate everybody into a few large urban centers, and figuring out how to make that urban land produce intensively for those people, we could spread those people out more so that the resulting population centers had more of a land base and didn't have to work so intensively, I think that would be ecologically a better model.

Brownfields and Urban Agriculture - Assessing The Challenges (Part 2)

This is the second part of a transcript of an interview I conducted last week with Clark Henry of the Portland Brownfield Program. In this interview, we discussed the prevalence of brownfields (areas of land polluted by commercial or industrial activity) in urban environments, and the implications for urban agriculture and food gardening. Today's post contains the remainder of that interview, in which solutions to brownfields are discussed. For the sake of continuity, I have also included all of the transcription from last week's post. My questions are in bold type, and Mr. Henry's answers are in normal type.

People talk about adapting to Peak Oil, economic collapse and resource constraints...and there are all sorts of responses, including trying to make things work where we live. Food systems are a big part of this, including urban gardening and urban farming. But some have pointed out the pollution of the urban environment, including pollution of soil due to lead. Telling people, “Don't grow food in the city; it's too dangerous,” won't fly as people find that they can't afford to rely on our present food systems. Yet the issue of pollution is valid. Can you comment on the scope of the problem, starting with lead pollution?

Sure, and just to qualify my statements, I am not a scientist, but an urban planner. I've been working with this [Portland Brownfield Program] project for eight years, so I have developed some understanding of levels and pervasiveness of contaminants. My wife, however, is director of the Josiah Hill III Clinic, a community-based nonprofit organization that does blood lead level testing for pregnant women and children in lower income neighborhoods and among communities of color.

The #1 source of lead contamination in Portland is lead paint, from older construction and older houses. The problem of lead contamination grows more severe as one moves eastward across the United States and as one goes into older neighborhoods. Scraping and sanding paint, or chipping and flaking of paint is the source of soil contamination in the home environment. In commercial and industrial areas, shipbuilding and shipbreaking, bulk oil terminals, old gas stations and old storage sites for leaded gasoline are sources of lead contamination.

Lead is a background element in nature, and agencies like the EPA and HUD publish environmental lead level figures that, in their view, “do not pose a driving risk to human life.” However, they also say that there is no safe level of lead in the human body. And there are documented detrimental effects to small children up to the age of 7 from exposure to lead. The City and County Health Departments partner with the State to publish guidelines for lead exposure, and there is a “Lead Hotline” available to City residents.

What other contaminants are a concern (including organic contaminants like organic compounds from leaking underground tanks)?

Petroleum of all varieties – gasoline, heating oil, motor oil, diesel fuel, bulk oil, and so forth. Former gas stations occupy a large portion of America's commercial corridors, and they were usually situated on corners where people drive by. Many sites of these former stations show few or no signs of such previous use; yet when people look into the records for such sites, they discover that, “Oh, a gas station was here!”

Modern gas stations operate under rigorous oversight by state regulators, but these older sites represent a mystery, an unquantifiable risk, and available databases don't do justice to this risk. Verifiable sites are maintained in two State (Oregon) Department of Environmental Quality (DEQ) databases: the Leaky Underground Storage Tanks (LUSTS) database, and the Environmental Cleanup Site Inventory. Some of the sites on this list have been cleaned up and re-used. All of these sites are candidates for State involvement in assessment and/or clean-up.

There are two stages of State environmental assessment. First is the Phase 1 assessment in which a consultant determines the history of the site, using sources such as the County library, building records, the Polk Directories and the Sanborn Fire Insurance maps. (In the 1950's, the Sanborn Fire Insurance company made very detailed maps of underground tanks for underwriting purposes.) Also, the consultant will visit the site to do a visual inspection, where he may notice old concrete pump islands or old gas station structures or fill ports for underground tanks.

The Phase 2 assessment follows once the consultant has determined that a site is a former gas station or dry cleaners' facility or metal plating facility or so forth. Phase 2 consists of taking soil samples or groundwater samples, or taking samples of the contents of barrels if there are barrels on the site, or taking samples of the materials of any existing buildings or structures on the site.

Once the assessment is finished, the level and type of contamination is compared to the desired future use of the site. The DEQ is concerned with limiting exposure to contaminants. Thus, a site that meets regulatory approval isn't necessarily cleaned up, but is configured in a way that limits exposure – via placing a parking lot or building foundation on top of contaminated soil so that people are prevented from coming in contact with the bare soil. This is called an engineering control. Another form of control, called an institutional control, consists of placing restrictions on the title and permitted uses of the site.

So then, it is possible that there are sites that would be under institutional controls that forbid their use for urban agriculture?

Absolutely. Unless you worked through a new way of getting the site cleaned up. And the City is working with some groups who are researching how to make brownfields both safe and functional for urban agriculture, whether it's small-scale community gardens or something larger. We're working with a group called Groundwork Portland, which is just a year and a few months old. It's part of a network called Groundwork USA, whose mission is to identify brownfields within environmental justice communities, and to have them assessed and cleaned up and re-used in a way that reflects the surrounding community. Not necessarily to eyeball these sites for condominium development or Starbucks, but to make sure that they are doing something for the people who live there – by protecting their health first, and then by insuring that these sites are used in a way that meets the needs of the people around them.

Groundwork Portland has a board of directors whose members come from several local organizations: Organizing People, Activating Leaders (OPAL); the Oregon Tradeswomen; and the Oregon Sustainable Agriculture Land Trust (OSALT). The Oregon Tradeswomen provide training in hazardous waste handling for brownfield work. OSALT owns property for agricultural use and they are doing research on appropriate agricultural development of urban properties. There is a project on 8th and Emerson in NE Portland, the “Emerson Garden Project,” now being undertaken by OSALT, and it is a 4000 square foot lot that was donated by the County through foreclosure.

The Portland Brownfield Program tested the lot and found that there were really high lead levels in a couple of spots. We (Groundwork Portland, OSALT and the City) are now trying to clean up the soil using phytoremediation (decontamination via plants), in order to turn this lot into a community garden. OSALT will test native plants on this lot, to determine their phytoremedial qualities with lead, in order that we can turn this into a site for food production and education at the same time.

What are the available remediation strategies, starting from the most expensive strategies down to those that are within reach of communities and non-profits?

That's a good question, and the answer is not obvious. Soil removal is one option. But this is very expensive compared to trucking dirt to a regular landfill. Dirt at regular landfills is simply used as a cover. But contaminated dirt requires removal to a toxic waste landfill. Fortunately, there is such a landfill in eastern Oregon, but the cost of trucking dirt there is over $700 a ton, compared to $70 a ton for removal to a regular landfill. And a ton of dirt is not that bulky. So soil removal quickly becomes very expensive, not to mention the cost of finding virgin, clean dirt and trucking it in to your urban agriculture site.

Another strategy is groundwater treatment, but this is an ongoing process that may last several years, and it too is expensive. When dealing with petroleum products, oxygenation and breakdown of compounds using bacteria and/or mushrooms is sometimes used. But this requires continual monitoring. The big questions for bioremediation, and indeed for all remediation, are “How long will this take?”, “How much will this cost?”, and “Who will pay for this?” These are often unknown until one gets into a project. Those who undertake such projects therefore take on a significant risk. Private developers must take this risk on themselves, but communities and tax-exempt non-profits can get help.

The Portland Brownfield Program focuses most of its efforts on helping community-based revitalization efforts, and I think we've achieved some good successes. But we also help private markets figure out remediation, as even large private firms who specialize in brownfield redevelopment sometimes get in trouble.

As far as nonprofits, there's a group, Southeast Uplift, that owns a former gas station on southeast 57th and Division. This land was given to them by the U.S. Marshal. This site was known to have underground storage tanks that had leaked. We helped them deal with the environmental liability issues and obtain the resources to deal with regulatory requirements for dealing with the site's past use. Our approach was straightforward – “dig it up and haul it away.” Fortunately, when we started digging out the tanks, we found very little contamination. But a site with identical usage and identical tanks might have had monstrous contamination – you just doesn't know until you start digging. We can test all we want, but the reality is that we drill a series of holes spaced a certain distance apart, and we make assumptions about what lies between those holes. If we find contamination, we will drill more holes until we don't find any more. This helps us determine the zone to be cleaned up. But the testing is expensive, and it is not fast. We can make educated assumptions about what we hope to find, and then have a plan B – a healthy contingency. Private developers have the luxury of having a large investment pool for cleaning up land for large projects, such as the Pearl District and South Waterfront. Things get tighter as the project size shrinks, though there are State and Federal grants available to tax-exempt organizations and nonprofits.

It sounds like there really needs to be a partnership with city governments in order to promote urban agriculture. The extent of urban pollution is fairly widespread. Are you saying then that people should not rush in blindly and grow vegetables in any bare patch of land?

Yes, that's a fair assumption. But it depends on what you're growing – does your tomato plant take lead out of the soil and store it in the fruit? It's questionable. Look at the literature to see what contaminants plants actually take up. The more serious threat comes not from eating the vegetables, but from working the soil – digging, planting, then bringing contaminated soil into your home.

The National Brownfield Conference was recently held in New Orleans. My co-worker Jen was there, and spoke at an urban agriculture session. There was also a woman named Anne Carroll of the U.S. Environmental Protection Agency who is working with city groups to help accurately communicate the risk – there really aren't a lot of regulatory standards that people can follow to determine what's safe; most of it is perception.

At that Conference, one researcher from the University of Washington said, “There's a very scientific approach to this; there's very little risk, so why address it? We haven't seen plants take up contaminants; all you're doing by applying this stigma to areas of land is stopping people from growing food. There's no risk; just go ahead and do it.” To me such a statement sends up a red flag – because people don't necessarily respond well to purely scientific reasoning. Even if that reasoning is communicated clearly, people don't always respond well. For instance, if you were told, “That soil is safe for you to garden in so long as you and your children aren't consuming more than 18 percent of your annual broccoli intake from that plot,” how would you feel? Perception of risk – perception of contamination is everything. Perception that a site is too dangerous to use may cause it to lie fallow, unused for anything- along with the perception that any assessment or remediation is too costly to undertake.

This is why partnership with a city government or other group that understands these issues can help in reusing sites. This is why we have been working with OSALT on the 8th and Emerson site, and why we have been working with Anne Carroll on accurately communicating the risk, and what to do to manage the risk. Not everyone who wants to start a community garden has a few hundred thousand dollars to remove the existing soil and bring in verified clean, composted new soil – that's unrealistic. So what's the alternative? To not use land? To use only the most pristine land? The vast majority of this world exists right in the middle, and if we want to use urban land for agricultural uses, we will be walking with some risk. That's okay, as long as we understand the risk and we take reasonable steps to limit it.

There are some obvious no-no's – you don't plant directly in extremely contaminated soil, for instance. And composting has been shown to bind contaminants in soil so that they are not mobile and can't be absorbed by plants. But some of this is subjective. And one size doesn't fit all. What's needed is an arsenal of many tools to deal with contamination in many situations.

One question is “What does sustainable cleanup really mean?” Does sustainable brownfield redevelopment consist of digging up contaminated soil and hauling it to a landfill? That just makes it someone else's problem. These landfills don't remain landfills forever. We're already dealing with the problem of closed landfills, and the big voids they leave in the urban environment. Landfills are big. Once they get closed, normally nothing happens on them. Will we try technologies and products that clean soil and groundwater? Do these products really do what they're supposed to do? Or do they actually make the contaminants more toxic?

Are there other cities throughout the U.S. and the world whose city governments are working to reclaim brownfield sites in their city limits for use in urban agriculture?

Yeah, absolutely. Philadelphia has been receiving national attention for their “Philadelphia Green” efforts. There's a group in Milwaukee, Wisconsin – I feel bad because I can't remember the man's name – but there's a gentleman who has done a tremendous job with aquaculture and urban agriculture, and he's doing it in a way that's educating tons of people, while generating enough funds to support itself; it's economically viable. There's also the Groundwork USA network. New York City is also looking at this as far as urban gardening, and they recently launched a very ambitious Brownfield Revitalization office.

Germany has a very interesting “Interim Use” philosophy. If a site is not being used, the government asks, “What can we use this for?” They don't have the same “property rights” gusto found in the USA, so the German government has a lot more statutory authority to put sites to use when their owners leave them fenced off and contaminated. Urban agriculture is one of the uses Germany has looked at for these sites, particularly in Leipzig.

In Indianapolis, my counterpart is Christopher Harrell, and he's looking at this as well. We're definitely not unique, but we like to think we're doing good work.

So here we are and someone wakes up to the insecurity of our economy and our industrial food system, and as he thinks of the need to start building local economic systems and systems of food production, he looks out his apartment window at the vacant lot across the street. Where does this person start?

Talk to the property owner if you're thinking of using some vacant land. Then, do your research on the site's history. In Portland, the Polk Directories are a good resource. Then, if you find that the site has a history that might have generated contamination, do some testing. Call the Portland Brownfield program. Also, talk to neighbors who know the history of the site.

But should you find that the site is contaminated, what do you do with that knowledge? You can compare your findings against the DEQ standards for agricultural use. Also, HUD and the City of Portland's Building Department have guidelines. But you have to be able in the end to look your neighbor in the eye and say, “Yes, this site is safe for use.”

Debrief: Mr. Henry provided some very useful information, which I am sure is greatly appreciated. Three things stand out: first, that pollution of the urban environment is a widespread and serious problem; secondly, that functioning in the urban environment therefore involves intelligently managing the risk from urban pollution; and thirdly, that providing sustainable and viable local economic systems – especially, local systems of food production – in urban areas will require us to learn to live differently. If we care about relocalizing our food, we will have to stop polluting our land, and we will have to stop supporting those businesses and activities of the present official economy that continue to ruin our cities. I know there are cities in China and on the African continent that are learning this the hard way.

One other note: The City of Portland's Bureau of Planning and Sustainability is hosting its “Urban Growth Bounty 2010” series of classes on urban agriculture and self-sufficiency. There will be 82 classes, covering topics such as urban farming, keeping chickens and bees, food preservation, and cheesemaking. Those who live in Portland and who are interested can go to http://www.portlandonline.com/bps/ugb for class descriptions and online registration links.
