My week of eating locally

Since my book A Small Farm Future makes quite a play for local self-reliance, I thought I should at least temporarily try to put my money (or, more pertinently, my produce) where my mouth is by only eating food produced on my farm for a week. I did this in the middle of September last year, when most of the folks in my household were away on a trip and I thought the exercise would be less distracting. I don’t suggest that by doing so I’ve proved anything much in terms of larger arguments about agrarian localism, but I found the exercise interesting nonetheless, so I thought I’d share a few observations about it here.

I made things easy for myself in various ways:

  • Doing it in September, when the produce is abundant
  • Allowing myself a few off-farm luxury items, provided they didn’t significantly meet my major dietary needs: salt, pepper, cinnamon, coffee
  • Living on a diversely productive small farm

But I made things hard for myself in various ways too:

  • Not preparing ahead of time to furnish things that I could have done with forethought
  • Not orienting my farm production over the years to full self-reliance, albeit that we’re moving increasingly in that direction. And therefore…
  • …having to forcibly deny myself various foodstuffs lying temptingly in the larder or on the plates of some of my fellow farm dwellers

So (note to self) here are some things I’d do differently if I try this again:

  • Grow more wheat ahead of time
  • Brew some beer ahead of time
  • Make some kraut ahead of time
  • Buy a cow ahead of time
  • Be sure that everyone around me is following the same regimen

Here are a few notes on some of the foods that I did (and didn’t) eat during my vigil.

Fat and oil: this was simple, because whenever we cook the lamb or mutton that we’ve raised on our grass we pour off the fat into an ice-cube tray (there seems to be a lot more fat in our home-grown meat than in the stuff you get from the shops) and then freeze it. The fat was great for making my food tastier, though I would have preferred vegetable oil for some things. And I probably used more animal fat during the week than I could sustain year-round at our level of productivity. In the absence of a productive sunflower patch and press, the alternative would probably have to be more boiled or baked food. But, seriously, who wants that?

Starchy staples: also simple – the answer was potatoes. And more potatoes. Which actually was fine – I love potatoes. But I did miss snacking on bread, and felt a vague sense of gastric unease through the week, which eased when I reverted to flour-based products. Perhaps I’m kind of a post-Paleo gluten-bothering farm boy, just that little bit more evolutionarily advanced than all those marrow-suckers out hunting deer on their men’s weekends. Or maybe it’s just a bad idea to abruptly change diet. Whatever, I’m planning to upscale my home wheat-growing in future. I did experiment with eating fat hen seeds (Chenopodium album), which apparently Britain’s prehistoric people ate as a staple – kind of a local version of grain amaranth. My gastric jury is out on that one.

Vegetables: super-simple, since I live on a veg farm. Plenty of onions, carrots, chard, lettuce, green beans, sweetcorn, you name it. An advantage of the diet was that I made better use of this bounty than resorting to the bread bin and the cheese tray. But it was a bit harder to snack on, and required more forward planning – which I’m not very good at (see above). And … if only I’d started a couple of jars of kraut a few days before having this madcap idea.

Fruit: I ate a lot of apples. Snacking between meals on fresh apples worked tolerably well, but didn’t quite hit the spot. Stewing apples for breakfast or dessert with a pinch of cinnamon worked better. I also picked wild blackberries from the hedges and sea buckthorn berries – painful, but delicious. The impetus to go out and seek fruit around the farm was one of the unexpected pleasures of the exercise. But it clarified for me that wo/man probably cannot live happily on fruit alone.

Meat: I usually eat meat about once a week, almost always the pork, lamb/mutton or occasionally chicken that we raise on the farm. I ate a little more during my homegrown week – partly perhaps to boost the tastiness. But also because my family are less enthusiastic than me about offal, so it was a good opportunity to clear some hearts, livers, gizzards and kidneys out of the freezer while the folks were away. If you’re going to kill an animal, Small Farm Future says – make it count.

The freezer of course was a useful resource during the week, locally powered by the sun falling on our PV panels, themselves locally produced in… Anyway, I’m drifting from the main point. In a truly low-energy society, I guess meat would likely be shared around more. The freezer as a killer of community?

I trapped and ate a couple of squirrels during the week, again boosting my meat intake. Since coming to the farm, we’ve planted thousands of trees, including a lot of nut trees. In the last year or so, the squirrels have moved big time into the woodland we’ve generously provided for them, seriously threatening the oaks, hornbeams and beech, while our nut harvest has curiously diminished in the same period. There are interesting underlying issues here about creating wild habitat on the farm, consequently losing crop to the wild creatures moving into the new niche, and then gaining something back by cropping them. I’ve never been that interested in trapping or hunting per se, but – as with most things – I’ve started to get more interested in it as a result of seeing the ecological cycles involved in it right in front of my nose. It’s easier to do this when you’re losing crop, especially to a voracious interloper introduced by human hand from overseas.

Dairy: oh my Lord, I dreamed of butter melting onto warm bread, hot milky coffee and tangy farmhouse cheese (hey, Cheddar is only twenty miles away – that’s nearly local, right?) And I have to confess to an indiscretion here whose details must forever remain a secret between me and my fridge. The use-by date was literally just days away, and wasting food is a crime…

I’ve never raised dairy animals because it’s seemed like too much work in our particular situation of being essentially single household veg growers with other work besides. And don’t say goats – as I just said, I’m a veg grower. But if I were truly gearing myself for food self-reliance I’d embrace dairy, especially within a wider community context.

Nuts: slim pickings on this front (see squirrels, above) and what we did have wasn’t quite ready. But this is definitely a good way to go for the self-reliant farm. Especially if you like eating squirrels – there’s nothing too vegan about nut crops in southern England these days, I’m afraid. Still, while on the subject of nuts, had the harvest and the timing been different, I suppose I could have made some hazel milk for my coffee instead of … [fifth amendment here]

Mushrooms: I’ve cultivated mushrooms from time to time over the years, but never really taken to it. I managed to harvest a couple of wild ones during the week, but the weather was dry and sunny and the fungi had other things on their minds, or whatever intelligence it is that they have down there. Perhaps this suggests a general side-note: there’s plenty of wild food around on the farm if you know where to look and you’re prepared to bide your time.

Beans: there were green beans aplenty, but my modest crop of proteinaceous drying beans wasn’t yet ready. That’s why I ate so much meat. Honest.

Eggs: an egg every day or so from our little flock certainly eased the burden. Served up with a salsa of onions, tomatoes and chillis from the farm, I barely even missed my regular Sunday breakfast croissant. The hens do get some feed bought-in from offsite, so strictly speaking perhaps I shouldn’t have eaten their eggs. Strictly speaking, there’s a lot of things I shouldn’t do…

Alcohol: if I’d planned ahead, perhaps I could have eased my way through the week in a homebrew-assisted haze. But I didn’t. And this lack of forethought was probably the single thing that contributed the most to the healthiness of my homegrown diet.

On the upside, I’d say that it’s surprising how congenial a homegrown diet you can produce without even trying all that hard if you have a small spread available. On the downside, I’d say that it’s surprising how hard it is to break from ingrained dietary habits like cheese and cereals, and how hard it is to focus production on these latter basics unless you’re singularly gearing yourself towards self-reliance. In some ways, the distance that even someone like me who’s well equipped materially and mentally to produce my own subsistence from fully achieving it is something of an eye opener. In my defence, I must point out that the focus of our farm for a good stretch of its existence has of necessity had to be upon proving to other people that it can earn a tolerable income. The challenge I now want to prioritise more strongly lies in proving to ourselves that it can produce a tolerable diet.

What’s in a number?

Chapter 11 of A Small Farm Future is predominantly a number-crunching exercise showing that Britain could feed a population of 83 million people using organic farming methods with locally generated fertility when yields are generally assumed to be 10% lower than the lowest bound of current organic crop yields, and with minimal fossil fuel use on-farm. The kind of analysis I did will be familiar to readers of this blog who followed my posts about feeding the Peasants’ Republic of Wessex, but in this case I applied the analysis to the whole country. I didn’t apply it to the whole world, however, and this is where I need your help (see below).

The basic take-home message of the analysis as I see it is that it’s possible for Britain to feed itself even with these stringent assumptions about population, yield and energy. So barring major climate tipping points or socio-political meltdown (both of which are possible, of course), I don’t believe that our food supply problems are ones of basic ecological carrying capacity. This is consistent with various mainstream studies, though not with the narrative that only capital-intensive, hi-tech, output-maximizing agricultures are capable of feeding us. Other organisms, if they’re capable of such thought, might take the view that their food supply problems are one of basic ecological carrying capacity as a result of human encroachment, but that’s another issue that I address elsewhere in the book – and, in passing, below.

I chose the population figure of 83 million – around 17 million more than the present UK population – on the assumption that Britain will be a destination for climate refugees in the near future. I plan to write more on this topic soon, but for now I’ll just underline my previous observation: even with a considerably enlarged population, Britain can feed itself with low impact and low yield methods. At the enlarged population of 83 million, this would involve a land take of 0.4 acres per person, with some slack in the system but with more land than presently devoted to cropping rather than grass. It’s tight. It involves potatoes. But it’s doable.

In the course of my analysis in Chapter 11, I mentioned that the agriculture I was proposing would require something like 15% of the working-age population to work directly as farmers (and more to serve the farm workforce indirectly). This number got picked up by various readers and reviewers and – as generally seems to be the way with bold quantification – prompted a certain amount of comment.

I think 15% is defensible, but to some degree I plucked it from the air on the basis of various assumptions that could be questioned, so I certainly wouldn’t defend it to the hilt. Arguably, the true number might be more. Conceivably, it could be less – though I doubt it. But what are the implications? What’s in a number?

One implication, I think, is that my analysis is sociologically plausible in the grand scheme of things. If it had turned out that the ratio of workers to consumers was close to or greater than one, then I would have had to conclude it’s impossible to feed ourselves with low impact methods, but I don’t believe this to be the case. As I mention on p.161 of my book, the 15% figure would put Britain in the company of countries such as Tunisia, Mexico and Ukraine today. There’s no strict comparability between what’s happening in these countries now and the kind of future scenario I’m describing. I make the comparison really just to suggest that 15% is not some outlandishly implausible figure.

People often point to the low proportion of the British labour force employed in agriculture (around 1%, currently) as if it’s an impressive historical achievement, rather than a source of past and probably future pain. But it does need noting that the true labour force involved in producing the country’s food and fibre is much higher, because we export the responsibility to grow labour-intensive products abroad, or else import from abroad temporary labour in those sectors, and this isn’t captured in the 1% figure. If you throw in all the processing, logistics and retail jobs that exist in the present food system but probably wouldn’t in a more self-reliant small farm future, then the 15% figure might start looking quite run of the mill. Indeed, as I mentioned in a recent post, it’s likely we’ll soon be in a situation where a lot of people will be looking for work to feed themselves at a time when many of the employment sectors that people have come to rely upon in modern society to provide for their needs will be contracting. So a plausible response to my analysis in Chapter 11 might be – “Just 15%? Couldn’t it be more?” The good news is, yes it could.

If 15% of people worked as farmers, that means on average that around one in six adult workers you know would farm, and the majority of families would probably have a personal connection to agriculture. It’s interesting to speculate how that might affect the standing of agriculture in society. One suggestion that’s come my way is that its standing would remain low, and the 15% would be dominated by the other 85%. It’s certainly possible, but I’m not sure it’s a matter of the simple numbers. There have been many societies historically with much higher proportions of people working directly in farming where the social standing and political opportunities of the farmers are low. But an interesting aspect of the epoch of modernity – manifested especially in the politics of populism – has been the idea that as citizens, individuals or humans, we are all of equal standing. It will be interesting to see how that issue plays out in the turbulent politics that are upon us.

One criticism I’ve received concerning this analysis is that showing how Britain can feed itself – even with numbers swelled by climate migration – is all very well, but it doesn’t prove that we can feed ourselves with local low-impact methods worldwide. On page 153 of my book, I give some reasons why the British case may not be wildly unrepresentative of the global one, but the criticism is a reasonable one all the same. I took the view that it was hard enough – and the assumptions were heroic enough – even to do a Britain-wide analysis. Trying to do a worldwide one would have been a step too far.

But maybe I can call on some external help in this regard. Greg Reynolds recently jotted some thoughts here about farm productivity from his US experience, and it looks like Jan Steinman might have some Canadian data up his sleeve. The main spirit of Chapter 11 was not fundamentally about me showing that the world could feed itself sustainably but about inviting people to think about their localities or regions and address their food sustainability for themselves. So … if anybody would care to do that – in whatever way they deem appropriate – I’d be delighted for them to send me their results via the Contact Form. I can’t promise that I will publish them or necessarily do anything with them, but if some sufficiently interesting analyses come my way I will try to make something of it.

When I’ve raised this issue in the past, I’ve received some semi-aggressive feedback along the lines of “It’s absurd for you to think my locality could be food self-reliant. I live in a city/desert”. Aside from noting that interesting final conjunction of words, my first blush response to this has usually been something along the lines of “Well, I’m sorry to hear that but, er … that’s not fundamentally my problem”. Ultimately, though, it is my problem as much as it’s anyone’s, and this is why I built a margin for climate migrants into my modelling for Britain. To be blunt, if your own modelling suggests your present local population couldn’t easily sustain itself from local resources, then don’t assume people will still be living in your locality long-term in their present high numbers. If, on the other hand, your modelling suggests your present local population could easily sustain itself from local resources, then don’t assume people will still be living in your locality long-term in their present low numbers.

A final observation. I’m writing this post on a sunny late May evening in the first spell of dry weather we’ve had after three cold, wet weeks. For two days, all day long and well into the night I’ve heard the distant whine of tractors in neighbouring fields busy playing catchup making silage. When they’re done, I know what the fields will look like – shaved bare as a skinhead’s pate from boundary fence to boundary fence.

When I think about my own site, with its mix of woodland, rather underused grassland, its small extent of heavily cropped gardens, its houses and outbuildings, I’ve sometimes felt guilty that we’re not maxing out the productivity like our neighbours. On the other hand, when you step from those fields into ours, the first thing you notice at this time of year is the sudden birdsong and the buzz of insects. You notice the large number of people living, working or playing on the site. You might notice the large diversity of its products – in addition to the meat and wheat furnished in such quantity by the surrounding fields, there’s wood for building or burning, fruit and nuts, a proliferation of vegetables, and quite a bit of wild food too. We could, if necessary, ramp up the per acre food productivity a little, especially if we brought more people onto the site to live and work. And we could probably do it without compromising too much on the birds and insects. But I don’t feel too guilty because, as I said above, I think Britain can feed itself well with low impact, low energy and low yield methods. The main problems lie elsewhere.

News flash

Just a quick ‘meta’ post relating to a couple of things, then back to my current blog cycle working through A Small Farm Future shortly after.

First, I’ve heard from various people that they’ve been having trouble accessing my site. My apologies – and my thanks for letting me know. I think I’ve now fixed the problem by reverting the permalinks to the basic format. This means that all the hyperlinks in my posts over recent years linking internally to other posts or comments on my website no longer work, but in the grand scheme of human suffering this seems a relatively minor problem. Perhaps at some point I’ll try to effect a better solution, but for the time being I’m happy that the site seems to be working. If you still have problems with it, please let me know by dropping me a line via the Contact Form. Provided it’s working.

On other matters, I’ve been remiss with providing updates on events etc. relating to my book. So here’s a quick bulletin.

On 17 June at 12 noon Eastern Time (USA), I’ll be in conversation about a small farm future with Jason Snyder and Ashley Colby on The Stoa – you can book here. And on 8 July at 10am Eastern Time, also on The Stoa, I’ll be in conversation with Vandana Shiva about international small farm futures.

On 14 June, I’m on a panel run by A Bigger Conversation on agri-tech and agroecology, now booking here, and on 15 June I’ll be speaking on a panel organized by Local Futures for World Localisation Day, details TBA.

I’ve also got a couple of other podcasts and a couple of articles in other publications in the offing, so I’ll keep you posted.

Meanwhile, I will try to keep this blog ticking along and even try to get out occasionally to do some actual farming. It’s fortunate that I have no social life.

Finally, another review landed recently – generally positive, while the areas of criticism are quite a propos for my next post, which will be with you soon. If you can access it…

Labour on the farm

The first draft of A Small Farm Future had a chapter called ‘Labour on the farm’ which didn’t make the final version. I needed to cut the length, and although there were parts of this chapter I was quite attached to, I felt I hadn’t nailed the issues as well as I’d like, so it was easy to spike. Some passages found their way into other parts of the book, but I’d been hoping to make good on the issue in this blog cycle with parts of the deleted chapter and my own more polished thoughts. Trouble is, I still don’t feel I’ve nailed this issue sufficiently. So instead I offer this post as a placeholder for a more distant day when I hope I can offer something more up to scratch.

What I’ll do here instead is provide a few brief thoughts on the topic prompted by a deeper dive I took recently into Francesca Bray’s fascinating book The Rice Economies (University of California Press, 1986) – an old book, but a very good one. Then I’m hoping I can come back in the future with something a bit more expansive.

A key organizing theme in Bray’s book is her contention that wheat in western countries and dryland cereal crops in general offer economies of scale in production that don’t exist in the case of the wet rice cultivation that dominates much of the populous regions of East, South and Southeast Asia. The combination of relatively scarce labour and relatively abundant land in the west (albeit that the latter was too often a function of colonial dispossession) created a dynamic of labour substitution and mechanization geared to increasing the per worker productivity of farming as an economic sector that’s come to be seen as exemplary of agricultural ‘progress’. In the wet rice regions, on the other hand, relatively abundant labour and relatively scarce land created a dynamic of agricultural development where the focus was using more (skilled) labour to increase the per acre productivity of the land.

From this point of departure, Bray unfurls an enormously detailed and sophisticated discussion of poverty, development, mechanization, landownership, credit, state formation, agrarian organization and much else besides which I hope to draw and elaborate from in future posts. But for now I’ll restrict myself to a couple of main points.

In certain situations of economic growth and capitalist development, there can be a compelling logic to agricultural labour substitution of the western kind. People quit the toilsome agrarian life for better paid jobs in industry or services, helping fuel an accumulation of capital and resources that redounds to the net benefit of all.

This is a pretty idealized vision of how capitalism works in practice, but it has a sufficient grain of historical truth to it in western societies to colour notions of a more labour-intensive agricultural future with a sense of regress and misplaced romanticism. Nevertheless, it matters where the accumulated capital and resources go. If labour substitution helps generate extra income that doesn’t find its way back to labourers, then to them there is no benefit. And this is basically what’s happening in the present phase of the global economy.

In the rice economies, on the other hand, capitalism was often built out from small-scale rice farming based on the intensive application of skilled labour, for example in Japan, Taiwan and South Korea. And even where it wasn’t, intensive labour on the farm created opportunities for crop diversification and increased rural income in relatively egalitarian rural societies.

Turning to the present and probable future global situation, I’d suggest that Bray’s analysis of the rice economies provides a firmer foundation for grasping the agrarianism to come than the recent historical experience of the western wheat economies. In the face of climate change, energy squeeze and socioeconomic crisis, the new normal will most likely be situations where a lot of people are gathered in the diminishing areas of the world still propitious for farming – in other words, where labour is abundant and land is scarce. Generally, capital will not be accumulating, but melting away. In these situations, the wise course will not lie in trying to release people from agrarian labour for largely non-existent jobs in a declining capital-intensive sector, but in intensifying agricultural labour to best produce the things that people need to live a good life locally.

If people were to do that, it seems likely they would move away from cultivating more than the minimum necessary amount of wheat, maize etc and towards more diverse cropping of fruits, vegetables and other such crops which have more the characteristics of wet rice than wheat. They respond to labour-intensive, land-sparing husbandry, which is why rich countries like the UK and the USA that are sold on labour-sparing agricultures terraformed to the largest possible envelopes for machine working import so much of their fruit and vegetables from abroad.

All of which is to say that we need a more nuanced approach to discussions of agricultural ‘efficiency’ than is commonly found in both mainstream and alternative agricultural circles (referencing this discussion with Ernie on the latter point, while conceding my elaboration here is sketchy – hopefully something to be filled out further in the future). In brief, efficiency is not an end in itself, but a way of saving on the means. So there is no virtue in having a labour-lean, capital-intensive agriculture when labour is abundant and capital is thin on the ground. It will not improve quality of life, which is a more powerful underlying aim than mere ‘efficiency’. In these circumstances, labour productivity will be less important than land productivity. And trophic efficiency may be less important than figuring out an agriculture that keeps people tolerably fed year-round, ideally with some periods of slack in the annual labour cycle that enables them to devote themselves to other pursuits. This is the kind of thinking that needs to be fleshed out in emerging agrarian societies.

Over at The South Roane Agrarian, Brian Miller has recently made much the same point implicitly with an enumeration of the labour on his farm over the last twenty-one years since he took it on. It’s a similar timespan since I turned to the farming life, though most of Brian’s numbers are well ahead of mine. Perhaps he’s more efficient?

Well, to compare farms and farmers is always to compare apples with oranges. Sometimes literally. But Brian closes his post with an irreducibly apples/oranges comparison of the kind that many farmers make.

“1,126 times one of us has said to the other, “This is too much work.” 7,929 times one of us has thought, What a lovely and a lucky way to live.

The challenge in the future will be trying to maintain that 1,126:7,929 ratio and make it the reality for as many farmers as possible. Because there won’t be many other options.

“How to kill a billion people” – a note on famine in small farm societies

The quotation in my title comes from a brief online review of my book from someone who clearly wasn’t a fan. I suspect the person concerned didn’t actually read the book, but no matter. For my part, it seems to me quite likely that a billion people or more will die prematurely if we don’t soon implement something like the small farm future that I describe in the book. It’s worth sitting awhile with that contradiction. What an extraordinary moment in history when different people think that either persisting with or not persisting with the regnant political economy might slay us in such unimaginable numbers.

Maybe I’ll come back to that in another post. Here, I just want to make a few points about famine in societies of the past, present and future, building on the analysis from Chapter 10 of my book – famine being, along with its companions war, disease and poverty, among the likeliest contenders for causing the untimely deaths of billions.

So, one of the objections to the idea of an agrarian localist or a small farm future indeed is the notion that they’re prey to hunger or famine in ways that modern societies are not. The term ‘subsistence farmer’ hardly helps, routinely associated as it is with other words like ‘scratching’ or ‘bare’.

This conceals a more complex reality. As I document in my book, ‘subsistence’ farmers have generally been well capable of creating a thriving and diverse livelihood for themselves, and building in safeguards against poor seasons. Indeed, you can make a strong case that small-scale local farming systems are more resilient to famine than the present nexus of large-scale commercial farms and urbanism. Maybe you can make the contrary case too. But the scale of farm operation will make little difference to the famines that will arise in worst-case climate, socioeconomic and strategic scenarios of the future. I see a turn to low-impact, local, small-scale farming basically as our best option now for avoiding those worst-case scenarios, and probably our only option for dealing with their consequences should they occur.

Nevertheless, it’s historically true that small-scale ‘subsistence’ farmers sometimes pooled resources on a larger scale in order to even out the inherent uncertainties of farming, especially in environmentally challenging situations. It seems the Chacoan people of what’s now New Mexico did this from around 700-1200 AD, creating a centralized state that drew various communities into its orbit. The Chacoan state’s main function was redistributive in the face of livelihood uncertainties, and when it could no longer continue to underwrite its people’s welfare they went their separate ways.

Contrast this with Pierre Goubert’s analysis of the peasantry in 17th century France:

The majority of the poor in the countryside farmed only two or three acres, and tried to live off this land completely, which they were more or less able to do as long as the weather was kind and the harvests were good. But they were all forced to find money with which to pay the royal taxes (which went up sharply after 1635), as they had to be paid in coin, as well as to pay seigneurial and other dues. That is why they always had to take their eggs, young cocks, butter and cheese, and the best of the fruit and vegetables to market, or to the neighbouring big house….They could keep little for themselves except what was strictly necessary or unsaleable1

It’s worth bearing in mind that underlying reality when contemplating state formation in early modern Europe and the splendours of its royal courts.

Or consider this report from a citizen of the Dutch town of Limburg in 1790 where trade was limited and farming ‘almost medieval’: “One ate and drank what the farm provided. Because very little could be sold, the farmer had ample to eat”2.

And a final example, running counter to Monty Python’s famous historical thesis, and with some bearing on recent discussions here about the healthiness of animal products: research on ‘Dark Age’ Britain in the aftermath of Roman departure suggests that “an increase in animal protein (including the dairy products that were gained from a greater emphasis on pastoral husbandry) and a concomitant decrease in the proportion of carbohydrates in everyday diets appear to have led to general improvements in health across the board, visible in increases in average height, better dental health, and higher recovery rates from infection”, and hence “the beneficial effect on peasant household economies of the withdrawal of Roman secular and military administration”3.

So against redistributive states like the Chacoan, or the de facto self-reliance of Limburg, perhaps we can counterpose more hunger-prone scenarios fostered by large predatory states – the Romans in Britain and early modern states in Europe among them.

In reality, the distinction is perhaps overdrawn. There were hierarchical elements in the Chacoan state, and there were ubiquitous uprisings and complex social alignments in Europe and elsewhere against the predations of overmighty states that ensured a redistributive aspect. This latter point is important, and I’ll be pressing it in future – predatory states are sometimes willing to extract resources from ordinary people up to the point of rank starvation if they can get away with it, but what often stops them from doing so is the ability of ordinary people to organize politically and make themselves protagonists in the political drama of the state.

My examples so far have all been quite a way back in the past. What of present and recent times? Famine expert Alex de Waal calls the first part of the 20th century “the most dreadful period of famine in world history”4 when modern leaders of various political colours such as Adolf Hitler, Winston Churchill, Josef Stalin and (later) Mao Zedong either actively created famines or connived at them in pursuit of their wider political goals. It’s perhaps worth noting that communist leaders like Stalin and Mao particularly inflicted hunger on the peasant classes whose activism was substantially responsible for putting them into power, in pursuit of breakneck industrialization policies dictated by Marxist-Leninist doctrines alien to peasant communism. Such famines of 20th century ‘development’ came on the heels of 19th century famines of colonial capitalism in other parts of Asia and Latin America. So there are good grounds for questioning the notion that famines were banished by modernization.

But more recently the incidence of major famines has declined, leaving us only with the small matter of chronic under-nutrition among possibly billions of people in a world that’s richer in total and per capita terms than ever before. ‘Developed’ or ‘middle income’ countries like Russia and China that experienced major famines in recent times are unlikely to experience them again in the near term, whereas ‘less developed’ countries, especially in sub-Saharan Africa, are on shakier ground. This prompts a narrative that capitalist or industrial development is the vanquisher of famine, and that we need more of it to finally banish it from the global scene.

I think this narrative is mistaken. I also think it rests on a horrifically ends-justify-means view of history that implicitly shrugs off the deaths of past millions as an acceptable cost of modernization. For all that, I’m as happy as anyone to celebrate the decline of major famines in the present. But it’s important to note they’ve declined largely because of an international humanitarian politics that considers famines unacceptable.

In A Small Farm Future I argue that we need to retain that humanitarianism, but I’m not sure that we’ll be able to do so under the auspices of our existing system of nation-states. There are already plenty of signs that this system’s mask is slipping, revealing the beggar-my-neighbour or beggar-my-populace face of the predatory state behind it. And that, in a nutshell, is why I think people are well advised to generate their own subsistence, or, better, to generate local communities that enable them to do so. If we don’t get on top of climate change (another challenge to which the existing system of states appears unequal) perhaps major famines are likely anyway, but if we leave our subsistence in the hands of the existing system of states we may well experience black swan famine events all the sooner and all the more devastatingly.

Of course, if everyone upped sticks overnight and headed to the countryside in search of a more sustainable subsistence (or if some neo-Maoist state forced them to), we certainly would experience famines and various other ghastly outcomes in short order. So the challenge is to see the writing on the wall before it’s too late and move more rationally towards a sustainable agrarianism. Or, as I put it on p.207 of my book, to choose a small farm future voluntarily in the present so as to avoid having a worse one imposed by Maos of the future.

Since we often extol the foresight of business leaders in modern capitalist society, perhaps we might learn from the example of internet billionaire Peter Thiel, who seems to have realized that in the final analysis you can’t eat money and has bought up a large spread of remote New Zealand farmland to safeguard against future uncertainties. Few of us have the means to do that, but what we can do is start working in any number of different ways to try to build a convivial agrarianism within our local communities. It won’t be easy, but if we pull it off then maybe some of us will be able to look back with pride at how we helped avoid killing a billion people.

Two hundred miles from Hartlepool

I’m going to interrupt my present blog cycle about my book A Small Farm Future for one post to comment on recent political events in Britain. Where this post ends up in fact is pretty relevant to some of the larger arguments of my book.

The events I’m referring to are last Thursday’s elections in which, among other things, many people across the country voted for their local councils, electors in Wales and Scotland voted for their national assemblies and – most prominent in the news – a byelection in the ‘postindustrial’ northeast English town of Hartlepool that had previously only ever elected a Labour MP opted for the Conservative candidate by a large margin.

That candidate, Jill Mortimer, has been described in the press as ‘a farmer’, but I haven’t seen any descriptions of her farm nor any discussion of agricultural issues around the election. As I’ll relate below, the issues thrown up by this election do seem destined ultimately to devolve towards farming, but only by a roundabout route which I shall attempt to unpick here.

Mortimer’s main electoral pitch seemed to be about creating more local jobs by ‘cutting red tape’. It surprises me that anybody would still buy the line that the lack of jobs in Hartlepool arises from an excess of ‘red tape’, especially when that line is spun by someone from a party that has increased red tape and reduced jobs by exiting the European Union. But Brexit has always been more about political symbology than rational calculation. It’s the Excalibur of contemporary British politics – the true leader in these times of trouble shall be known by the fact they can extract a well-honed Brexit from the recalcitrant stone of Brussels.

Hartlepool was held by Labour in the 2019 election under present Labour leader Keir Starmer’s more left-wing predecessor, the much vilified Jeremy Corbyn – though perhaps only because back then the non-Labour vote was split between the Brexit Party and the Tories, who on Thursday vacuumed up the votes from the now defunct Brexit Party. Since Starmer took over, he’s ruthlessly purged the left-wing elements of the Labour Party (including Corbyn) and gone on a quest for the Holy Grail of electability by trying to recover votes from historically Labour-voting but often socially conservative postindustrial working-class constituencies in the north like Hartlepool, talking tough on immigration, going large on Union Jacks and patriotism and avoiding saying anything at all left-wing that might get him into trouble. It seems to me the byelection result is a straw in the wind for how that will turn out. Over the last few years, the Conservative Party has transformed itself into a right-wing populist coalition of the classic kind, and Starmer’s search for electability through winning back working-class votes via ‘pragmatic’ social democracy seems to me to be destined for failure and many more years out of office for as long as he continues trying to out right-wing populist the right-wing populists.

Eventually, I suspect the contradictions of right-wing populism will undermine it, the Excalibur of Brexit will lose its lustre, and Alexander Boris de Pfeffel Johnson’s obvious preference for the billionaires of London over the ‘red wall’ electors of the north will count against him. But by then the last remnants of the centre ground in English politics will probably be gone, perhaps replaced on the one hand by an even more red-toothed and nativist English nationalism, and on the other by whatever political grouping can speak for a more radical and less belligerent alternative. On present performance, that grouping is unlikely to be the Labour Party.

The loss of the centre is so disorienting that old-guard social democrats like Will Hutton are trying to explain the Conservative Party’s success in terms of a new grassroots Keynesian centrism that the left can emulate. Well … I don’t mean to deny the impact that resourceful local politicians can have on creating new jobs and a bit of local buzz, but to enthuse about regional airports, free ports and public-private finance initiatives is to miss the larger structural reasons why Johnson’s billionaires are destined to remain in London, not to mention the large social-ecological reasons why the entire economy is running on empty.

Indeed, for all the chatter at the moment about Hartlepool, I’d suggest that much the most important political event in Britain – in fact, the world – this year will be occurring 200 miles to the northwest, with the COP26 meeting in Glasgow. If the outcome of this meeting is a binding international agreement to reduce greenhouse gas emissions to zero by around 2050, starting right now, then maybe I’ll breathe easy again enough to think it’s worth debating how to create jobs in Hartlepool – though it’s hard to see airports or free ports fitting into such a scenario.

But if, as I fear, no such agreement is forthcoming, then the time is upon us to stop caring about which politicians can best mobilize non-local capital to create new jobs, and to focus on local survival instead. In various talks I’ve given after the publication of my book, I’ve been struck by how out on a limb I seem to be with this view that the climate path we’re currently on will spell the end of the political and economic world we now know – not necessarily because of its direct environmental effects, but because of the knock-on human implications. So I felt a certain grim vindication, hardly satisfaction, when I recently read Anatol Lieven’s book Climate Change and the Nation State, which made much the same point.

It interests me that Lieven, a conservative nationalist with considerably more mainstream gravitas than me, has come to many of the same conclusions that I did in my own book about the shape of future politics – in particular, on the need for what he calls civic nationalism (and I call civic republicanism) where people can find ways to meet the challenges of the climate emergency collectively in their communities. On many points, I fundamentally disagree with him, but in the face of that larger agreement I see little virtue in dwelling on them. The main problem as I see it is that Lieven’s own vision succumbs to the same problem he detects with more leftist versions. Lieven is scornful of greens and leftists who invoke a “nice, ideologically positive apocalypse” of open borders, multiculturalism, intersectionality and so on, which he sees as “ideological luxuries”. But exactly the same could be said of his own view of a nice, civic nationalist apocalypse in which all the contradictions and nasty bits of nationalism have somehow been excised.

The difficulty that both of us – in fact, all of humanity – faces, is that there’s no very obvious politics that can take us from where we currently are in the world (which isn’t that great for multitudes of people) to congenial forms of human society in a world of climate breakdown. To my mind, that doesn’t mean we should give up trying to find it, but I think a certain honesty about how the odds are stacked and a scepticism towards easy optimism and solutionism is called for.

Unfortunately, that easy optimism and the soft pedalling of climate change remains a common tic of contemporary politics. In a review of ecological economist Tim Jackson’s new book, Oliver Eagleton wrote that “environmental theorists” including Leigh Phillips (sic) have raised “serious questions about the practicability of degrowth models … can degrowthers prove the ecological benefits of their agenda justify the risk of plunging millions into poverty?”

The ecological, economic and political illiteracy of Eagleton’s comments is staggering, but this kind of thinking remains standard fare in mainstream political discussion – a world that’s still all about jobs, listening to voters, attracting investors, cutting red tape, growing the economy, investing in the future, positive visioning. A world of getting Brexit done, making America great again, green transitions and finding the Holy Grail.

I think we need to dispense with these emotional props and face the challenges of the future with more honesty. But I’m fearful of what might happen if and when we do, which is perhaps faintly visible in outline in Hartlepool and many of the other election results. On the one side, for all their differences, people like Anatol Lieven, Jeremy Corbyn or Keir Starmer trying to articulate some kind of rational collective politics, and on the other, a nativist politics of friends and enemies where might makes right.

The sliver of hope that I tried to promote in my book is that in the world to come it will probably be more obvious than it is right now that livelihoods must be wrested locally from rural land, and in countries like Britain there are very few people currently who are doing that – which is a problem, perhaps, but also a blessing, because it will be easier to create new peasantries of disparate origins in such circumstances.

So instead of a farmer gaining political advantage by promising to cut red tape and create more jobs, instead of trying to reinvent the industrial past of England’s northeast and reinvent the voter base of the political party that once represented the people who worked in those industries, I think we’d all be better off if we focused on creating more actual jobs in local farming. After COP26, it’ll be easier to say whether those jobs are more likely to arise by design or default.

The single biggest way to reduce your impact on planet Earth…

…is a vegan diet. Well, at least it is according to Joseph Poore. But I have an alternative suggestion. The single biggest way to reduce your impact on planet Earth is to stop thinking there’s a single biggest way to reduce your impact on planet Earth, or that bang for your buck metrics of this kind are helpful in formulating how best to live.

Here, I’ll elaborate that suggestion, grounding the discussion in the debate about veganism versus livestock farming. The debate gets a lot of airtime, and I’ll only touch lightly on a few aspects of it here. I say a little more about it in Chapter 8 of my book A Small Farm Future. As is often the case, it’s potentially endless, because the assumptions people bring to it and the contexts they apply them to are different. But hopefully I can at least clarify a few of those assumptions and contexts here.

Poore co-authored a widely-publicized paper a couple of years back that argued livestock products from even the best performing commercial farms have higher impacts across various environmental indicators than their vegetable counterparts (eg. each gramme of protein from beef has a higher impact on greenhouse gas emissions, land use, soil acidification, water eutrophication and scarce water drawdown than a corresponding gramme of protein from pulses). There are some aspects of the paper I’d quibble with, but by and large I don’t think there’s anything that’s demonstrably incorrect factually about the claims it makes (I can’t honestly say the same about some of Poore’s wider claims reported in the media).

However, as I said above, context is everything. So if your focus is the environmental impact of each unit of protein from ‘commercial farms’ of different styles, then without doubt the bean farm outdoes the beef one. But suppose you’re a smallholder living a low energy life, not a commercial beef farmer, and suppose you keep a cow or two. Your cows could help you do all or any of these things:

  • save work (including carbon-intensive machine work) by routing fertility around the farm
  • balance fertility in a timely way over the year (applying the summer’s surplus to the spring’s deficit)
  • turn inedible or harmful growth (unused marginal grazing, weeds) into food or fibre
  • help you manage your farmland in a low carbon or possibly even carbon-negative way
  • turn short-run or low value produce into longer-run or higher value produce (lard, butter, cheese) that improves your quality of life
  • provide transport and traction (oxen)
  • furnish useful coproducts (horn, bone, sinew, gut etc.)
  • provide a store of value and wealth
  • provide a source of companionship and pleasure…

…oh yes, and maybe provide some meat or milk too.

If you somehow factor all that into your calculations, then keeping cows may not look quite such a shabby option after all – especially since many of the points above are potentially carbon saving.

The same point applies to other kinds of farm livestock, all of which have their niche on the non-commercial farm as tappers, cyclers or producers of nutrients or other useful matter that are impossible or laborious for people to access directly. Their meat or other edible products are the bonus skimmed from the top of a larger, low-energy ecological labour.

But should you factor all that into your calculations? It’s not as if you’ll find a packet of multipurpose smallholder cow mince in the fresh meat aisle at Tesco’s, for reasons copiously analyzed over the years on this blog.

Meanwhile, the whole issue has become hyper-politicized on numerous fronts. On the one hand there’s the “Joe Biden Stole My Hamburger” brigade of entitled consumerism that’s been in the news lately, coopted by a rightwing politics of personal choice and freedom. On the other there’s the “pasture-fed beef can feed the world and sequester all our carbon emissions at the same time” shtick of regen-ag ultras. And on the third hand (three hands being a useful trait for a farmer) there’s the vegan “single biggest way to reduce your impact” or “cows are worse than cars” position.

None of these lines of argument withstand much scrutiny. It probably is true that if you find yourself in the supermarket in need of protein and you care about the intricate biotic web of the world and the human place within it then you’re better off buying beans than beef. And if the idea of not buying something to lower your environmental impact offends your sense of personal choice and freedom, then you probably shouldn’t be pushing a little cart around the supermarket picking stuff that other people have grown for you off the shelves and then standing in line to hand over your hard-earned cash to the giant corporate concern that owns it.

But I think we need to get beyond this arena of what I call ‘shopping aisle ethics’. If enough people care about the intricate biotic web of the world and the human place within it, then the multipurpose smallholder livestock-raising I mentioned earlier will become normalized by design because – as argued at length throughout my book – it’s hard to see a better way of providing for ourselves while caring adequately for that web than creating small farm-based communities, and low-energy smallholdings lacking in livestock are less efficient and more laborious places than ones that have some. Plus maybe you’ll find some real choice and freedom on your own small farm.

If, on the other hand, enough people don’t care about the intricate biotic web, then multipurpose smallholder livestock-raising will probably also become normalized, this time by default, because we’ll blow ourselves through the planetary boundaries that make other ways of life feasible, and folks with their noses to the grindstone will raise livestock to do a job of work.

Either way, we’ll be eating a lot less meat than consumers in the rich countries do today, and we’ll be worrying less about the single biggest way to reduce our impact on planet Earth, and a little more about the single biggest next job on the farm. If the latter is the main thing we’re worrying about, then the remaining denizens of ‘Planet Earth’ will probably have less to worry about from us.

Finally, a large part of the climate case against meat has to do with methane emissions from ruminants, but – as I discuss in more detail in A Small Farm Future – the conventions of methane accounting easily lead us to overstate the climate forcing impact of livestock and understate that of fossil fuels and other non-agricultural sources (which produce more methane than livestock globally anyway). But the wider issue is that the global fossil fuel economy underlies and enables the outsized global livestock economy. Without the former, we’d have to source much of our fibre, fertilizer and energy for industry and transport from the lands where we live, and this would put a constraint on the livestock we could raise on those lands that fossil fuels effectively remove.

So perhaps, after all, I’ve argued my way to the opposite of my opening gambit. There is one single biggest way to reduce your impact on the Earth – dispensing with fossil fuels. If we do that, livestock numbers will pretty much take care of themselves and will have minimal environmental impacts.

However, to make that happen isn’t a ‘single’ thing, and certainly not a thing that can be done by a simple choice in the shopping aisle. Instead, it’s a journey of many steps. And the journey will end for many people with a small farm where they live and work. For those with a taste for meat the good news is that when they get there they can raise a little livestock. In fact, they’d probably be unwise not to. The livestock they can feasibly raise won’t amount to a hill of beans as much meat as people in wealthy countries are used to eating at present. But if they’ve raised it themselves, with minimal off-farm inputs and maximal on-farm benefits, I think it’ll taste all the better gramme for gramme. Same goes for beans.

Alternative agriculture: a polite discussion

In this post I’m going to sweep up some issues left hanging from comments under my last one, along with further issues lurking within Part II of my book A Small Farm Future, and all wrapped up inside a larger point of contention. Each of these issues on its own could fill several posts, so we’re in for a bumpy ride.

Let’s start with the larger point of contention. In the face of contemporary environmental and agricultural problems, there’s a danger of succumbing to magic bullet, techno-fix thinking without paying attention to trade-offs and deeper complexities, or to socio-political issues. This applies of course to mainstream ‘light green’ or ‘ecomodernist’ thinking, with its enthusiasm for nuclear power, GMOs, smart cities, vertical farming and all the rest of it. But it also applies in the ‘alternative’ sector when ideas like regenerative agriculture, perennial grains, permaculture or intercropping (or, for that matter, solar panels, veganism etc.) are touted as one-stop solutions to our problems. Likewise, I think, with social solutionism. There’s no single or simple way of organizing society that ticks all boxes.

Over the years, I’ve set out my stall in straightforward opposition to mainstream techno solutionism, but also in what I’ve intended as friendly scepticism toward alternative solutionism. Alas, some of the debates prompted by this latter position haven’t always been that friendly. I don’t really want to go looking for arguments with anyone working broadly within alternative agriculture, permaculture or human-centred economics – though I’ve learned the hard way that people have different judgements about the boundary between ‘looking for discussion’ and ‘looking for arguments’.

One of these arenas is regenerative agriculture, discussed (all too briefly) in Chapter 6 of my book, where imaginations sometimes run wild with the idea that tweaking tillage and cover-cropping practices will enable farmers to feed the global population long-term without fundamental change to the organization of farming and society, while sequestering all our carbon emissions stably in the soil. As Gabe Brown has it, “Naysayers often question whether regenerative agriculture can really heal our planet while producing nutrient-dense food”1.

There’s quite a moral loading there on the ‘naysayers’, and a certain vagueness around what ‘healing the planet’ and ‘nutrient-dense food’  might mean. So I’d rephrase the sentence as follows: “It’s worth asking whether various specific regenerative agriculture practices could, if generalized, prevent soil erosion and soil nutrient depletion while sequestering human greenhouse gas emissions worldwide and providing enough food to feed expected human populations long-term.” And, whatever the associations with being a ‘naysayer’ might be, I think it would be wise to entertain the notion that the answer to this question might be no.

I talk about some of the emissions and food production issues implied here in more detail in A Small Farm Future. In terms of soil nutrients, Joshua Msika nicely summarizes the regen-ag approach as a focus on carbon as the limiting element: “Carbon provides the energy the soil micro-organisms need to mobilise the other nutrients: The energy to fix atmospheric nitrogen, the energy to mine locked-up phosphorus, etc.”

I find this plausible, including Joshua’s use of the word “mine” to refer to phosphorus and other non-gaseous plant nutrients – suggesting both the creativity of regen-ag thinking and the dangers of it falling into dogma if it’s presented as a simple techo-fix. For all the sound and fury of regen-ag advocacy, I’ve seen no estimates within it for the rate of this mining – and certainly not in the places where my critics told me to look. Happily, Clem Weidenbenner rode to my rescue under my last post, suggesting that currently there’s enough phosphorus for us to mine from the soils for about 100 years. This doesn’t seem to me an awfully long time, civilizationally. When you place it alongside looming energy scarcity I think it suggests not so much that regenerative agriculture can heal the planet while producing nutrient-dense food but that folks would be well advised to invest in compost toilets, cycle organic matter, move out of cities and learn how to garden organically.

It’s curious to me that alternative ag types who are generally quite wised up about the dangers of depleting resource pools and the benefits of ecological cycling seem so defiantly insistent that farmers can keep conjuring minerals out of nothing. To be fair, I did my share of defiant insisting myself some time ago, indeed to an embarrassing degree, so I guess I can understand the power of wishful thinking. The more so because modernist culture does like to insist on its ability to escape from limits (just so boringly ‘Malthusian’), to the extent that clever and well educated people like Pascal Bruckner can dismiss environmentalist enthusiasm for composting human waste as a crazy ‘scatological fantasy’, an ‘epiphany of the excremental’2, rather than, er, an attempt to cycle scarce and vital minerals through the agroecosystem.

So … count me in with carbon farming, nutrient dense food, healing the planet, cover cropping and soil protection. Also with cutting out fossil fuels, deurbanization and rural settlement, closed loop nutrient cycling, labour-intensive horticulture and compost toilets. I can’t really imagine a lasting ‘regenerative agriculture’ without that second list.

Another area of alternative agriculture where I’ve exercised my contrarian muscles over the years is in questioning an over-emphasis on perennial over annual crops. Don’t get me wrong – I think more perennials and fewer annuals is a necessary step. I continue to think that Mark Shepard goes way, way over the top when he writes “Every human society that has relied on annual crops as staple foods in their diet has collapsed. Every single one”2, and I still think it’s high time people in the alternative agriculture movement stopped demonising annual crops as some kind of original sin, and stopped over-promoting the labour and yield benefits of perennials. Nevertheless, we surely do need to embrace more perennial agricultures and try to transcend the tyranny of annual ‘staple’ crops – the ‘arable corner’ that I discuss in Chapter 5 of my book. Perhaps in the past I didn’t sufficiently acknowledge that the pro-perennial boosters have their heart in the right place. So mea culpa and note to myself: yes to more acorns, hazels, sea buckthorn, pendulous sedge and beef in my diet. Whereas sourdough? Maybe see you next week.

Finally, a word about intercropping and polycultures. On page 121 of A Small Farm Future, I write “Attempts to prove that diverse crop polycultures yield more biomass, calories or other nutrients acre for acre haven’t been conspicuously successful, except in the special and non-generalisable case of legume mixes”. Is that true? Well, maybe or maybe not – I’m interested in your opinions. The more important point, I think, is one that I go on to make on pp.121-2:  “[mixes] of annual and perennial food crops, orchards, pasture and woodland [work] as reasonably integrated whole with complementarities that support human livelihoods on the farm and in the nearby town, while lowering external dependencies for energy and other inputs.”

Whatever the optimum mix or non-mix of crops might be at plot or field level in relation to desired outputs like yield, I suspect that at the township, farmscape or foodshed level, a small farm future will be a crop diverse farm future.

In summary: two cheers for regenerative agriculture, perennial cropping, intercropping and naysaying. Now let the argument discussion begin…

Some further thoughts on organic fertility

I’m going to continue my theme from my last post about organic fertility in future farming, picking up on a few of the very interesting comments that people made in response to it. Apologies that it’s taken me a while to get around to this follow up post – work just keeps finding me. In fact, I’m going to keep this briefer than originally planned so as to keep my head above the water.

Anyway, many thanks for the comments. For the most part, I’m not going to respond to named individuals, instead focusing on the general issues people raised. I’m going to do it in the form of a set of numbered propositions that hopefully will clarify my position, and perhaps also act as a spur to further discussion. A lot of the comments focused in one way or another around the framing of my post, so I’ll begin with that.

  1. The title of my previous post – ‘Can organic farming feed the world?’ – was probably a poor choice and arguably falls into a Lakoff framing trap, with its underlying implication that non-organic (‘conventional’, ‘industrial’ or synthetic nitrogen) farming faces no parallel question. For my part, I do not assume that non-organic farming as it’s generally practiced at present will be able to continue to feed the world (in fact, I strongly suspect it won’t be able to). All the same, I think it’s legitimate to ask the same question of organic farming, and follow through on the implications.

 

  1. The structure of my post followed David Connor’s paper, which looked top-down globally at the amount of biological (‘organic’) nitrogen fixation (BNF) and the amount of synthetic (‘non-organic’/‘industrial’) nitrogen fixation (SNF). An alternative approach is to look bottom-up locally – how much land and other resources do I need to provision myself without SNF in the place/region/country where I live? This latter approach is precisely the one I took in Chapter 11 of my book A Small Farm Future for the case of the UK – and the answers I came up with is ‘not very much’ and ‘yes, we can easily provision ourselves using only BNF’. But you have to make a lot of detailed assumptions to undertake the bottom-up approach, which are difficult enough for a single country or bioregion, let alone for the whole world. So there’s something to be said for looking top-down globally as a complementary approach, starting from the reality of how much BNF and SNF there actually is in the present world.

 

  1. Still, the problem with this top-down, status quo approach is that it often mistakes the way things are for the way they should or must be. I like to think that my previous post gently undermines such assumptions in Connor’s paper. We don’t need to devote cropland to livestock production. We can devote more labour to global agriculture than we presently do. We don’t need to waste so much food. And so on. In this way, I think we move the debate more towards the bottom-up approach. Can we get by globally with only BNF? Probably yes, just about, if we change some of our framing assumptions about how we do agriculture globally.

 

  1. But why does it matter whether we can get by with only BNF? In the world as it presently is, at the level of the individual farm, my answer is – it doesn’t. Indeed there may sometimes be a case for using SNF and, at the farmer-to-farmer level, I concede there’s much to be said for avoiding a polarized SNF versus BNF debate (with the proviso that this onus also falls on pro-SNF, anti-organic advocates like Connor). However, I think it does matter at the level of the total farm system, because SNF requires highly complex industrial infrastructure, and it readily enables farmers to engage in non-resilient and unsustainable cycles of productivity gain. I don’t think we can build congenial and renewable cultures long-term on this basis. So if it turns out we can’t feed ourselves without SNF, then we’re in quite a predicament. Happily, that doesn’t really seem to be the case. Suggesting how that may be so was the main point of my previous post.

 

  1. There are different ways to increase productivity in agriculture, of which N fixation methods are only one. Another is devoting more human labour to smaller, more intensively worked holdings and farmscapes. I don’t think it’s possible to overstate the importance of this more labour-intensive approach for a renewable human future – it’s central to my book, and to this blog. Implicitly, though, more labour-intensive farming probably means more BNF. It certainly means more careful N cycling.

 

  1. Underlying the N debate is another one about the place of livestock in our farming and of meat in our diets. I’m not going to wade too deeply into that here, although I’m aiming to devote a future post to it (see also Chapter 8 of A Small Farm Future). Commenters on my previous post touched on the issue of using soy to manufacture ‘fake meat’ more efficiently than of using it to feed livestock that are slaughtered for meat. Again, I see this as a present vs future food system issue. In present circumstances, maybe there’s something to be said for favouring ‘fake meat’ over actual meat. In future circumstances, there will be something to be said for a world of smallholdings and agricultural commons where livestock are kept primarily to improve the efficiency of tapping and cycling nutrients in low energy farming systems. Either way, we will be producing a lot less ‘real’ meat for human consumption (though its consumption across the population may be better distributed).

 

  1. Thinking in terms of BNF and SNF rather than organic/conventional farming is useful to avoid missing the various ways in which N from SNF finds its way into organic farming or gardening, which people then too easily assume derives from BNF. This is probably even more important when it comes to phosphate rather than N. The study cited by Shaun Warkentin suggests that around 70% of P inputs in a sample of organic farms in France came from conventional sources, and the main conventional source for P is unsustainable mining. Ultimately, the long-term necessity to cycle rather than mine P could be a key factor propelling humanity back to a predominantly rural, distributed and agrarian human geography.

 

  1. The excellent possibilities for BNF and for P cycling in small-scale paddy rice farming systems suggest they are a renewable farming approach of choice for the future where they’re feasible. The methanogenic nature of paddy farming (and of smallholder livestock keeping) is irrelevant to its long-term sustainability, whereas short-term elimination of fossil fuel combustion is critical. Economic development policies should support small-scale paddy farming and avoid explicit or implicit fossil fuel dependence.

 

  1. With characteristically effective sleuthing, Steve L has uncovered the figure of 28 Mt of fertilizer lost annually in the food supply chain. With this corrected for, the need for SNF potentially shrinks to near zero – but I’m not sure how much N there is in this 28 Mt, so I’ll leave that tantalizing prospect hanging for now.

Can organic farming feed the world?

I discuss various aspects of so-called ‘alternative’ agriculture at some length in Chapter 6 of A Small Farm Future1, and I don’t intend to retrace many of those steps here. But there’s a couple of further things I do want to say in this blog cycle. Here, I’ll focus on organic farming.

On page 125 (and also page 150) of my book I cite a 2007 study by Catherine Badgley and co-authors2, one of whom is Jahi Chappell who sometimes comments here, so I’m hoping he might weigh in with his thoughts on this post. Their paper suggests that organic agriculture based on biological fixation of nitrogen is capable of meeting global food demands without reliance on industrial synthesis of nitrogenous fertiliser (from now on in this post I’m going to use the symbols N to refer to plant-available nitrogen, BNF to refer to biological (or ‘organic’) nitrogen fixation and SNF to refer to synthetic/industrial nitrogen fixation). Interestingly, the Badgley paper also suggest that while organic yields in rich countries are typically lower than their ‘conventional’ counterparts, the opposite is often the case in poor countries, a point to which I’ll return.

Since the publication of my book, I’ve become aware of various papers by Professor David Connor critiquing the Badgley paper, and more generally the notion that it’s feasible to feed the world without SNF. Although I identify with organic/alternative agriculture and have never used synthetic N in my own farming, I don’t take an absolutely purist line about it in relation to the global food system. If SNF is necessary in some circumstances, I’m not going to lose sleep over it. Still, SNF is an energy-intensive business requiring a complex industrial infrastructure. Given energy and other constraints in the future, if it turned out we needed SNF at similar levels to the present to feed the world this would be quite a stumbling block for arguments favouring low-energy agrarian localism. So it’s worth considering Connor’s arguments.

The main objection to the possibility of ‘feeding the world’ through organic agriculture based on BNF is that it’s typically lower yielding than SNF-based agriculture. This yield penalty has two components – lower yield acre for acre in the corresponding crops, and the fact that organic agriculture has to build N via rotations with leguminous non-food cover crops that further increase its land-take. Connor argues that the Badgley paper failed to take proper account of this second issue, and therefore overestimated the global potential of organic agriculture.

Whatever the rights or wrongs of that point, I’m going to take a different tack and consider some figures that Connor presents3. He says that 21 Mega tonnes (Mt) of N are fixed annually by cover crop legumes, with the total amount of BNF estimated between 33-46Mt. This contrasts with 113Mt of SNF, giving the measure of the challenge – apparently a major shortfall in the possibility of feeding the world organically.

But let’s take a closer look at these figures, most of which are based on a 2008 paper by David Herridge and co-authors4. I’m going to see if I can find some ways to narrow the discrepancy between BNF and SNF reported by Connor, which at worst is over a fivefold difference in favour of synthetic (113:21). It’s rather a back-of-the-envelope job, and some of the underlying issues are quite complex, so of course I’d welcome any comments or refinements.

The Herridge paper that Connor draws on proposes a larger amount of global BNF than Connor of 50-70Mt, as follows:

Pasture & fodder – 12-25Mt

Rice – 5 Mt

Sugar cane – 0.5Mt

Legume cropland – 21.45Mt

Non-legume cropland – <4Mt

Extensive savanna – <14Mt

 

Connor’s 33-46Mt figure presumably comes from adding legume cropland to the lower and higher bounds of the pasture & fodder figures (21+12=33, 21+25=46), so he’s ignoring the other forms of BNF reported by Herridge. This seems reasonable in the case of extensive savanna, little of which is likely to find its way back into the agro-ecosystem, but not so reasonable in the case of the other, admittedly fairly minor, BNF sources – rice, sugar cane and non-legume cropland. So I propose to incorporate these into the BNF figure. This gives a range of 39-56 Mt BNF, something of an improvement on the worst-case ratio, but still at best only half the SNF figure.

Let’s now look at livestock. According to the FAO, 33% of global cropland is devoted to producing livestock fodder. This is a choice that humans make – in fact, that primarily rich humans make – and I’d suggest not a wise one in view of the energy and other squeezes we face. Therefore, I think we can drop it from our modelling. We need to design a renewable food system that can feed the global population adequately, fitting livestock into it where we can, rather than designing livestock systems to meet the demand for meat which compromise food access and renewability.

I’m not sure quite how to quantify this adjustment, however. Soy is a major fodder crop, and also an N-fixer, so possibly the proportion of global cropland devoted to producing fodder has lower SNF needs? Obviously, some of the N that’s fixed ends up in the fodder and not in the field, although some of that then ends up in manure which may be available as BNF. But I’m not sure how best to adjust for these pathways – and of course there are a lot of non-N fixing fodder crops. So for now I’m going to allocate 33% of SNF proportionately to the 33% of fodder cropland, until someone suggests a better methodology. So that’s 33% of superfluous SNF, which takes us down to 76 Mt SN.

SNF used for boosting the productivity of long-term pastures for livestock is, I’d argue, another superfluous use. I don’t have global figures for this. Rough calculations for the UK suggest that we use about 30% of our SN on pastures. I suspect the figure is much lower in most other countries. I’ll arbitrarily assume that it amounts to 3% globally – further information welcome. This would take total SNF down to 73 Mt.

The next thing to look at is human waste. Each of us excretes about 20g of N per day in urine and faeces – which amounts to a lot of N aggregated across the human population over a year. Here in the UK, we already do a pretty good job of getting this back to the fields, but at quite a high energetic cost in water treatment and transport. One of the arguments in favour of ruralization is that it’s much easier energetically to get human nutrients back into the fields when people are actually living on them (a graver threat to urbanism than many seem to appreciate, especially in relation to phosphate rather than N). Let’s assume we can get 75% of the N contained in global humanure into the fields (again, I’m open to a more refined analysis with this parameter). This shrinks annual global SN to 25 Mt.

Then there are various losses associated with international trade, processing and consumer waste, which could be vitiated in a society based on local food production. I estimate these at a rough and ready 19% on the basis of a paper by Mike Berners-Lee and colleagues5 – admittedly one with a somewhat different focus, so again I’m open to more nuanced clarification. This reduces SN to 20 Mt – about the same as BNF from legume cropland, and much less than is currently fixed by BNF overall.

There are various other ways in which we might nibble away at this remaining SNF figure. For example, we might invest more in plant breeding and crop development to maximize edible matter per unit of N input and increase organic yields, which has scarcely been an agronomic priority in recent times. Or we might increase the N input from wild margins either directly or through livestock intermediaries, or cut back on certain kinds of N-demanding production, or improve crop production through other means like irrigation, or improve N uptake in existing crops. Maybe we could reduce SN by such means to around 10 Mt, down from the initial figure of 113 Mt. The possible fivefold excess of SN over BFN (113:21) may now be reversed (10:56) – perhaps to the extent that it’s no longer wholly implausible to imagine a low-energy small farm future that’s largely an organic one?

A final point. Professor Connor writes:

“My concern is for the resource-poor farmers, especially in Sub Saharan Africa, who overwhelmingly are targets for help and advice to apply organic methods from misguided community organizations based in other countries. Soil fertility is so low there after at least a century of intensive nutrient extraction without replacement that denial of the need for N fertilizer makes the process of agricultural renovation impossible”5

 

This concern seems a worthy one. If the world does still need a modicum of SNF, the people who unquestionably need it most are poor (usually small-scale) farmers in regions like Sub-Saharan Africa. Whether those advising these farmers to apply organic methods are ‘misguided’ is another matter, because there’s a long history of poor farmers getting locked into dependency on high-cost inputs like synthetic N, largely to the benefit of those selling the inputs rather than to the farmers. So the advice of movements like Zero Budget Natural Farming in India for poor farmers to farm organically without SNF seems to me well founded. The higher yields for organic farming in poor countries reported in the Badgley paper seemed to arise from the availability of extension and advice helping farmers to manage inputs more systematically. This should surely be the first option to explore in improving yields before moving on to more energy-intensive options like SNF.

But perhaps we can frame this point about nitrogen equity the other way around. Given the grossly unfair distribution of global resources, rich countries should stop trying to squeeze greater productivity out of their own farming systems through profligate (or, perhaps, any) use of SNF, and make SN available at low or no cost to poor farmers in poor countries, should the latter feel the need for it.
