Nuts and rationality

We have just finished planting, mulching and guarding 2,500 hazel and walnut trees over 25 acres of steep, south-facing grazing land. It will be four years for the hazels, and eight for the walnuts, before the first small harvest.

I will never see the walnuts in full production, but have been sustained, through the bitter east wind during planting, by a vision of being wheeled out in my later years to sit under the trees as the nuts drop, with a flagon of cider and an air rifle to see off squirrels.

This project is driven by passion and deep rationality, not economics. The idea is to introduce biodiversity by mixing old, complex pasture, grazed by animals, with nut trees overhead; to grow food on marginal land without disturbing the soil, and to sequester carbon underground.

But as much as that makes profound sense (to me anyway), and does have the potential to one day become economically viable and create a path others may follow, measured in £ alone it is currently madness.

Why? 70 per cent of hazelnuts are grown in eastern Turkey. A global market in a relatively non-perishable commodity has driven the price down so far that hand picking the nuts is only economical using child and migrant labour in questionable conditions.

Inevitably, the response has been to mechanise; most of the remaining 30 per cent of hazelnuts are grown on large, highly mechanised farms. The machinery requires a billiard-table flat surface, with all other plants removed by herbicides or cultivation; and the cost of the machinery begets bigger farms, which beget bigger machinery, and an environment stripped of diversity in an attempt to shape nature to the machine. Depressingly, this pattern is the same globally for virtually all crops: from almonds, tomatoes and wheat to pigs, hens and dairy cows.

We are told that following economic dictates like this is rationality. And now we are supposed to believe that, with carbon accounting and some tinkering at the edges, the same band of ‘rationalists’ will lead us out of the environmental crisis their approach created.

Much as I acknowledge the power of capitalism to create innovative solutions, we must balance what is measurable (be that carbon or money) with a more profound, complex and longer-term rationality, which incorporates multiple, harder-to-measure indices that we may only partially understand. Sounds a bit like nature? Maybe it is. I worry this is too much to ask of free market economists – but I have ordered another 2,500 trees for next year.

    Well done and well said Guy. I hope I live long enough to be able to order nuts for my veg box and that politicians will listen to you!

    Yes, yes, yes! I've been on the hunt for UK produced nuts and there a very minimal suppliers so very much looking forward to a harvest down the track. Also on the hunt for some organic UK cold-pressed rapeseed oil but no luck finding it. Seems we have field everywhere with the yellow flowers spread across the countryside but we import other oils rather than making from our own. Hoping availability of this will increase too :)

    Before covid and the reduction in the food ranges from Riverford there was a rapeseed oil they sold produced by a grower somewhere a bit north. Don't remember the name but it obviously exists. Hope this helps

    Hi Kerianna2006, companies such as Clearspring and Biona sell organic rapeseed oil, but the only cold-pressed rapeseed oil produced in Britain is from the Stringer family’s Yorkshire fields. You can find them online at

    My late uncle was passionate about walnuts and planted lots round the place. They should start producing nuts soon. I need to resurrect the annual squirrel shoot! That was his favourite event of the year.

    I'm passionate about walnuts too and have a harvest of about 150 kilos a year of the French 'Corne' variety, which renders excellent oil. Apart from taking the walnuts to a local mill to be pressed, I have started making walnut cookies to support a new local grocer's, which sells a range of organic cereals and flours. I've never used any chemicals in my garden. The chickens and Indian Runners no doubt help to keep up the fertility.

    Guy Singh-Watson

    Guy Singh-Watson has over the last 30 years taken Riverford from one man and a wheelbarrow delivering homegrown organic veg to friends, to a national veg box scheme delivering to around 80,000 customers a week. Tired of meetings, brands and the assumption that greed is our predominant motivation, Guy converted the business to employee ownership in 2018, using the proceeds to buy a small farm and return to growing organic vegetables. In common with many of Riverford’s new co-owners, Guy is an advocate of using business to shape a part of the world, however small, to be kinder, more considerate and sustainable; more like the world most of us want to live in.  His weekly newsletters connect people to the farm with refreshingly honest accounts of the trials and tribulations of producing organic food, and the occasional rant about farming, ethical and business issues he feels strongly about.


    The power of 'what if?'

    All too often we default to dystopian images, rather than allowing ourselves to believe that it could actually be amazing: more connected, happier, healthier, with cleaner air, better food.
