A short story inspired by Rattan Lal, “Restoring Soil Quality to Mitigate Soil Degradation”, Sustainability (2015)

I. The Question

At twenty-five, at a quarter past one in the morning, sitting on the floor of a rented room in Gaborone with my laptop balanced on a crate, I typed the most honest question I have ever asked a search engine:

How do I restore my depleted Kalahari soil which was not actually depleted, it just sucked from the get-go?

I wasn’t expecting an answer. I was expecting nothing, or a gardening shop trying to sell me a bag of something. I think, really, I was just saying it out loud to the only listener awake at that hour.

Some background, so you understand why a grown man was arguing with the internet.

My nkoko — my grandmother — has a piece of land outside Letlhakeng, on the eastern edge of the Kalahari. Our family have ploughed those masimo, those fields, for as long as anyone remembers. Sorghum, beans, a few melons in a good year. Nkoko is eighty-one now and her knees have retired, even if she hasn’t. That year she called me and said, in the tone she uses for things that are not questions, “Christopher. The lands need you.”

I was working in an office doing data reports for a logistics company. I was good at it and I didn’t care about it, which is a dangerous combination at twenty-five because it feels like the rest of your life. So I said yes. I drove out every weekend that first rainy season with a hired tractor and a head full of plans.

And I failed. Properly failed.

The sorghum came up thin and yellow. The beans sulked. The rain, when it came, didn’t soak in; it sat on the surface for a moment and then vanished into the sand like it had somewhere better to be. Two weeks after a storm the ground was dust again. I dug a hole a metre deep and it was the same pale, loose, orange sand all the way down. No dark layer. No crumbs. Nothing that looked like the soil in the pictures.

My cousin Kabelo, who farms near Molepolole, laughed when I complained. “What did you expect? It’s the Kalahari, monna. It’s a beach without the sea.”

So that was the question. Everybody talks about restoring degraded soil, about getting land back to how it was. But my land was never anything. You can’t restore something to a golden age it never had.

II. The Paper

Somewhere in the results that night was a scientific paper: Restoring Soil Quality to Mitigate Soil Degradation, by Rattan Lal of Ohio State University, published in 2015 in a journal called Sustainability.

My first reaction was irritation. Restoring. There it was again. The paper was written for people whose soil had fallen from grace. Mine had never been anywhere near grace.

But it was free to read and I was already awake, so I read it. And I’m glad, because by four in the morning I had stopped being irritated and started taking notes.

The first thing that stopped me was a number. Lal argued that soil needs a certain amount of organic carbon — the dark, living, decomposed material that gives good soil its colour and its grip — and he put the critical threshold at roughly 1.1 to 1.5 per cent by weight in the root zone. Below that, soil struggles to hold water, hold nutrients, and hold itself together.

I had a soil test from the agricultural office in my bag. I dug it out. Our sand came in at about 0.2 per cent.

Not a little short. Five to seven times short. It was like being told that the healthy weight for your height is seventy kilos when you have been forty kilos since the day you were born.

I sat there and laughed, the tired laugh you do when the universe has confirmed your worst suspicion. My soil really did suck from the get-go. Now I had a peer-reviewed reference for it.

But I kept reading, and two things in that paper changed everything.

III. What Lal Actually Said

The first was a sentence I nearly skimmed past. Lal wrote that the indicators of soil quality differ among soil types, climates and land uses. He gave examples — the intensively farmed plains of India need different measures from the old weathered soils of the semi-arid tropics. Later he said plainly that there are no universally applicable techniques, that every approach has trade-offs, and that the answer has to be site-specific.

Read that again if you’re a farmer on sand. The paper wasn’t telling me my soil was a failure for missing a European or American standard. It was telling me to stop comparing. To work out what good looks like for this soil, in this rain, under this sun, and work towards that.

The second thing was the way he framed the whole problem. He didn’t talk about soil as a fixed object that is either good or bad. He talked about processes. Soil gets better or worse depending on what goes in and what comes out. He described a downward spiral — bare ground, erosion, lost carbon, dying soil life, less growth, less to put back — and an upward spiral, where cover, carbon and life feed each other and the soil gets steadily more able to look after itself.

That’s when the question in my head changed. I had been asking, how do I get my soil back to where it was? That was a dead end, because it had never been anywhere. The better question was: which way is my spiral turning — and how do I make it turn up?

Lal set out three basic strategies. Stop losing what you have. Put in more carbon than you take out, and look after the life in the soil while you’re at it. Strengthen the cycles of water and nutrients. He was blunt that there’s no silver bullet.

Fine, I thought. No silver bullet. But I can count. And I could see straight away that every year I had been doing the opposite of all three.

IV. What I Had Been Doing Wrong

Every spring we ploughed. Of course we did. Everybody ploughs. My grandfather ploughed with oxen and we ploughed with a tractor, and in both cases we turned that sand over and left it bare and hot under a sun that can push the surface past sixty degrees.

Lal is hard on ploughing. He describes how indiscriminate tillage, combined with stripping crop residues off the land and leaving it bare, drives soil downward. On a soil that starts with almost nothing, I was burning through the little carbon it had like paper on a braai.

After harvest, the cattle came in and ate everything down to the ground. Then they wandered the lands all dry season, trampling. Lal has a whole section on rangelands that might as well have had our village’s name on it: overgrazing and trampling reduce plant cover, break down soil structure, cut infiltration, increase runoff and erosion. He cited work from right next door in South Africa showing that when grass cover is lost, soil carbon goes with it.

And here’s the thing I found most painful. Our land wasn’t actually empty when we started each season. I just didn’t know how to see what was there.

V. Learning to See

The next weekend I didn’t take the tractor. I took a notebook and walked the lands with Nkoko, slowly, at her pace, which is the pace of someone who has looked at the same ground for sixty years.

“You want to know where the good soil is?” she said, when I explained what I was trying to do. “I could have told you. You never asked. You young ones ask your telephones.”

She took me first to a corner of the field near the old cattle kraal, abandoned since before I was born. The sorghum there had been taller, greener. I had put it down to luck. “That’s where the cattle slept for twenty years,” she said. “Twenty years of dung. You think that goes away?”

Then she showed me the camel thorn trees — the big old mogotlho standing alone in the lands, which we always ploughed around. Under each one, in the shade, the sand was darker. Leaves and pods had been falling there for a century, and the roots go down tens of metres to water no crop can reach. Each tree was a little island of fertility in a sea of sand.

Then the termite mounds. I’d always thought of them as a nuisance, something to knock flat. Nkoko said the old people used to carry termite soil to their gardens. Lal mentions termites too — alongside earthworms, as builders of soil structure, mixing and binding the ground, and as signs of healthy tropical soil.

And then she bent down, slowly, and touched the surface of the sand where nobody had walked. It was dark, almost black in places, and crunchy, like burnt sugar.

“This skin,” she said. “When you were small, this was everywhere. Now only where the cows don’t go.”

I went home and looked it up. It’s called a biological soil crust: a living layer of cyanobacteria, algae, lichens and mosses, millimetres thick. In drylands like the Kalahari it binds the loose sand against wind, and some of those organisms pull nitrogen from the air into a soil that has almost none. It forms over years. A herd of cattle can break it in an afternoon.

I stood in my rented room in Gaborone and felt ashamed. My soil hadn’t sucked from the get-go. It had been poor, yes. Stingy, honest, harsh. But it had its own systems, its own slow economy of carbon and nitrogen, its own islands of wealth. And every year we’d been ploughing them up, grazing them down, trampling them flat, and then complaining that the land gave us nothing.

There’s a line in Lal’s paper I copied out and stuck above my desk. He wrote that when people are poor, desperate and hungry, they pass on their sufferings to the land. He’s right, and it’s not a judgement on anyone. My grandfather’s generation ploughed and grazed hard because they had to eat this year. But the paper also showed me the way out: stewardship and desperation can’t live in the same place. If you want people to look after land, you have to make looking after land worth their while.

VI. Turning the Spiral

So I made a plan. Not a restoration plan. A building plan. Lal’s three strategies, translated into Kalahari.

Stop losing what we have. No more ploughing the whole field. I marked out rows and only opened the soil where seed would go. I talked to my uncles — this took three long evenings and a lot of tea — and we agreed to keep the cattle off the lands for the growing season and most of the dry season, and to bring them in only briefly, in one part at a time, to graze stubble and leave dung. Lal calls it controlled grazing at appropriate stocking rates. My uncles call it “Christopher’s nonsense,” but they agreed to try it for three years.

Put in more carbon than we take out. This was the big one, because there was so little carbon to start with. I couldn’t afford to cover forty hectares in compost. So I concentrated. I dug planting basins — shallow pits a little wider than a dinner plate, in rows — like the zaï pits farmers use in the Sahel. Into each one went a shovel of old kraal manure, a handful of termite soil, and some charcoal. The charcoal came from the sickle bush and black thorn that have been creeping across the grazing land for years, choking out the grass. Clearing it helps the rangeland, and burning the wood slowly, low on oxygen, gives you biochar. Lal mentions biochar as a carbon-rich amendment that can build soil resilience. I couldn’t prove it would work in our sand. I could prove we had too much bush.

The rest of the cleared bush I chipped and spread between the rows as mulch, so the sun hit dead branches instead of bare sand. Lal is clear about this: keep the ground covered, return the residues, don’t strip the land. After harvest, the sorghum stalks stayed where they fell.

Strengthen water and nutrient cycles. Every basin caught rain. Instead of running across the surface and vanishing, water pooled for a few minutes where the manure and the seed were. I made little half-moon banks on the slight slopes to slow the runoff. I planted cowpeas — dinawa — between the sorghum, because beans feed nitrogen into the soil through their roots. I planted morama, the wild Kalahari bean that has lived here far longer than we have and laughs at drought. And I stopped ploughing around the camel thorns and started planting young ones, because a tree is just a slow, patient fertility pump.

None of it was glamorous. Most of it was digging. In that first year I lost four kilos and the skin off both palms.

VII. Small Numbers

Here is what I want you to understand about building soil in the Kalahari: the numbers are small, and the small numbers are everything.

In the first season, the basins worked and the rest of the field didn’t. Sorghum in the basins came up dark green and twice as tall as anything outside them. Kabelo drove over to see and stood there with his hands on his hips for a long time before he said, “Hm.”

In the second season, the crust started coming back on the edges of the rows where nobody walked. Thin patches. Dark specks. I photographed them like a proud father.

In the third season, I had the soil tested again. The open sand between rows was the same, about 0.2 per cent organic carbon. But the basins — the ones that had been fed three years running — had roughly doubled.

Doubled from 0.2 to around 0.4. Still nowhere near Lal’s threshold. Somebody from Iowa would look at those figures and feel sorry for me. But I knew what they meant. They meant the spiral had turned. Not everywhere, not quickly, but in hundreds of little circles across Nkoko’s land, the soil was holding more water, feeding more life, growing more plants, putting more carbon back. Each basin was a tiny upward spiral.

And Lal’s paper had taught me the most important thing about spirals: once they get going, they feed themselves.

That was the year I stopped thinking of my soil as a problem I’d inherited, and started thinking of it as a long-term investment that compounds — and it was the year I knew I couldn’t go back to the office.

VIII. Why This Is Bigger Than My Nkoko’s Field

I’m not the only person with this problem. Not even close.

Huge areas of southern Africa sit on deep sand like ours. Lal points out that sub-Saharan Africa has some of the most degraded soils on earth, in a harsh climate with fragile soils, and that degradation there is shrinking a finite resource faster than almost anywhere. He also makes a point that I think about every day: simply adding chemical fertiliser or improved seed is not enough, even though it’s what well-meaning advice often recommends. Without organic carbon, fertiliser on our sand just washes straight through and past the roots.

What happens to soil here doesn’t stay in the soil. When the land fails, young people leave for the city — I was one of them. When the cattle have nothing to eat, families sell them in a drought for nothing. When the grass goes, the dust rises, the bush moves in, and the rain that does fall runs off instead of soaking in. Climate change makes the dry spells longer and the storms harder. People talk about the polycrisis — all these problems tangled together — and from where I stand, a lot of the knots are tied in the top thirty centimetres of the Kalahari.

Which means that a lot of them can be loosened there too.

IX. The Decision

I’m twenty-eight now. I’ve just finished the first year of a master’s in soil and land management at the agricultural university in Gaborone. My dissertation is on planting basins and bush-derived biochar in Kalahari sands, and Nkoko’s land is one of my trial sites, which she finds hilarious. “My grandson the professor,” she tells the neighbours, “who learned about dung from me.”

She’s right. Half of what I know, she knew. The other half came from a paper by a man in Ohio who has never seen Letlhakeng and was writing about soils on the other side of the world. The most useful thing I’ve done is put those two kinds of knowledge in the same room.

What I want to do with my life is simple to say and hard to do: help farmers on poor sands build soil they never had. Not restore. Build. Work with the extension officers, the cattle owners, the women who run most of the masimo and get the least credit for it. Test what works field by field, because Lal is right that there’s no silver bullet and the answer is always site-specific. And find ways to make stewardship pay, so that nobody has to choose between feeding their family this year and keeping their land alive for the next.

X. To Anyone Holding Bad Soil

So if you’re out there at a quarter past one in the morning, typing your own version of my question — if you’ve been handed something that was never good to begin with, whether it’s land or a job or a place or a start in life — here’s what I learned.

Stop asking how to get back to a golden age you never had. Ask which way your spiral is turning.

Look properly at what you’ve got before you plough it under. There are islands of fertility in every bad field: an old kraal, a tree, a termite mound, an old woman who has been watching the ground for sixty years and is waiting for you to ask.

Concentrate your effort. You can’t fix forty hectares at once. You can fix one basin. Then another. Then a thousand.

Measure honestly, and celebrate small numbers. Going from 0.2 to 0.4 is not failure because it isn’t 1.5. It’s the spiral turning.

And be patient. The Kalahari doesn’t hurry for anyone. But it does keep score — and when you start putting back more than you take, it notices.

My soil didn’t suck from the get-go. It was waiting for someone to stop taking from it and start building it up.

Pula. Let it rain.

I. The Plot

The first thing my grandad ever taught me about soil was that you could listen to it.

I was seven. We were on his allotment at Meersbrook, the one halfway up the hill where you can see the whole of Sheffield laid out below you like somebody’s dropped it — the tower blocks, the old works chimneys, the Park Hill flats painted in their bright new colours, the trams sliding along the valley floor. He handed me a fork and told me to push it in slowly and pay attention to the sound.

“Hear that?” he said. It was a soft, crumbly sort of noise, like biting into a biscuit. “That’s good earth. That’s alive.”

I didn’t think much of it at the time. I was seven, and I wanted to find worms.

Eleven years later I was standing on the same plot with the same fork, and the ground didn’t make that sound any more. It made a dull, flat thud, like stamping on a car park. The fork went in about four inches and stopped. When I levered it up, the soil came away in a grey slab, smooth on the bottom where the tines had polished it. No worms. No smell, even — and good soil has a smell, a dark, sweet, after-rain smell that I hadn’t realised I’d been missing until I knelt down and couldn’t find it.

Grandad had died in the February. He was eighty-three, and he’d been poorly for a couple of years before that, which meant the plot had been let go — first the edges, then the beds, then everything. The allotment society wrote to my mum asking whether the family wanted to keep the tenancy or give it up. There was a waiting list as long as your arm. Mum said she didn’t have the time. My uncle said he didn’t have the knees.

I said I’d do it. I was eighteen, working thirty hours a week at a coffee place on Division Street, and I’d dropped out of a business course after one term because I couldn’t see the point of any of it. I didn’t know the first thing about growing food. But I couldn’t stand the thought of a stranger digging up Grandad’s rhubarb, and I think, if I’m honest, I needed somewhere to be that wasn’t my bedroom or behind a till.

So in April I went up there with a borrowed fork and a lot of good intentions, and the ground went thud.

II. What Went Wrong

I did what anyone my age does. I looked it up on my phone.

I typed “allotment soil hard grey no worms” and got a hundred forums full of people arguing about clay. Somewhere around one in the morning I ended up on a page of search results for “soil degradation”, and one of them was a scientific paper.

It was called Restoring Soil Quality to Mitigate Soil Degradation, by a man named Rattan Lal, from Ohio State University, published in 2015. I nearly didn’t open it. Scientific papers, in my head, were things written by people in white coats for other people in white coats. But it was free to read, and I was awake anyway, and the title had the word restoring in it, which was what I wanted to do.

I didn’t understand all of it. But some parts of it went into me like the fork should have gone into the ground.

He wrote that soil is non-renewable on a human timescale. I had to read that twice. I’d always thought of soil as the most ordinary, endless stuff in the world — it’s just dirt, it’s everywhere, it’s what you wipe off your shoes. But the paper explained that it takes so long to form that, for us, within our lifetimes, once it’s gone, it’s gone. Something you inherit, and either pass on or spend.

Then there was a figure about how much was already spent. Around a third of the earth’s land surface, the paper said, is affected by some kind of soil degradation. One estimate he cited suggested soil’s ecosystem services — growing food, filtering water, holding carbon, all the quiet work soil does that nobody pays for — had fallen by sixty per cent between 1950 and 2010.

Sixty per cent. In sixty years. Roughly my grandad’s adult life.

I sat on the edge of my bed with the phone glowing in my hand, and I thought about that grey slab on the end of the fork, and I thought: it’s not just us. It’s not just his plot. It’s everywhere.

III. The Downward Spiral

The bit that really got me was a diagram. Lal called it a downward spiral.

The idea was simple enough even for me at one in the morning. You plough the ground too much, or leave it bare, or take everything off it and put nothing back. The soil loses its organic carbon — the dark, rich stuff made from rotted roots and leaves and dead microbes. Without that carbon, the soil can’t hold itself together, so it crusts and compacts. Water can’t get in, so it runs off the top, taking the best soil with it. The little life down there — the worms, the fungi, the bacteria — starves. The ground grows less, so there’s less to put back. Less going back means less carbon. Less carbon means more compaction. Round and round, and down and down.

And here’s the part that made the hairs on my arms stand up: the paper said that once degradation gets going, it feeds on itself. It speeds up. It doesn’t just sit there being bad — it gets worse on its own.

I looked at Grandad’s plot in my head and I could see it, the whole spiral. Two years of nobody tending it. Weeds that came and died back and got pulled out in a hurry by my uncle one autumn and thrown on the tip instead of on the compost. Bare ground through two winters. Sheffield rain — and anybody who lives here knows about Sheffield rain — hammering on soil with nothing to protect it. The beds Grandad had built up over forty years, gone grey in two.

I’d always heard climate change, floods, food prices and wars talked about as separate disasters. That diagram joined them up. The paper pointed out that degraded soil can stop being a store for carbon and start releasing it instead — turning from part of the solution into part of the problem. It talked about polluted rivers, people’s health, the economy.

Later I learned there’s a word for that — for lots of crises that tangle together and make each other worse. People call it the polycrisis. At the time I just thought: it’s all one thing. And the thing is under our feet.

IV. The Floods

I was too young to remember the big Sheffield floods in 2007, but I grew up on the stories — the Don bursting its banks, Meadowhall underwater, water pouring off the hills down streets like rivers.

After reading the paper, I started asking a question I’d never asked before: where does the water come from?

Obviously it comes from the sky. But it doesn’t fall straight into the river. It lands on the hills first — on the moors, on farmland, on gardens and allotments. And what happens next depends on the ground it lands on. Lal wrote about the soil-water nexus, about how healthy soil lets water soak in and filters it, and how degraded soil sends it sheeting off the top. Healthy ground is a sponge. Dead ground is a roof.

That spring I took the train out to Edale and walked up onto Kinder. Up on the plateau there are these great black gullies where the peat has been stripped away, deep scars with bare, dark walls, where two centuries of industrial soot — Sheffield’s included — killed the moss that held everything together, and fire and weather did the rest. And then, in other places, there were patches of green: little tufts of sphagnum and cotton grass, where people had been out restoring it, blocking the gullies, spreading cut heather, planting moss by hand.

I stood up there in the wind with my hood up and I realised I was looking at both of Lal’s spirals at once. The black gullies were the downward one. The green patches were the other one.

Because that was the bit of the paper that had kept me awake until three, not one: there was an upward spiral too.

V. The Upward Spiral

Lal didn’t stop at the bad news. He laid out the whole downward spiral, and then he laid out how to turn it round.

He said the degradation could be reversed. Not easily, and not with one magic trick — he was blunt that there’s no silver bullet, and that every place needs its own answer depending on its soil, climate, people and money. But the basic recipe was there, and when I boiled it down it was something I could actually understand.

Stop losing soil. Keep the ground covered so rain and wind can’t strip it.

Put more carbon in than you take out. Feed the soil with living roots and dead plant matter and compost and manure, so the organic matter builds back up. He gave a number for it — a threshold of around one to one and a half per cent organic carbon, below which soil struggles and above which it can start to heal itself. I liked that there was a number. It meant there was a line you could get back over.

Look after the life underground. The worms and fungi and bacteria do the actual work of building structure, gluing tiny particles of soil into crumbs, opening up the little channels that let air and water in.

And stop disturbing it so much. Stop ripping it open every year.

He described the practices that do all this, which together get called conservation agriculture: leaving crop residue on the surface as mulch, growing cover crops instead of leaving ground bare, mixing organic and mineral fertilisers sensibly, and cutting out ploughing. Do those things together, properly, and you start an upward spiral. More carbon means better structure. Better structure means water soaks in. Water soaking in means more growth. More growth means more carbon going back. Round and round, and up and up.

And at the very top of his diagram — I remember this because I actually laughed out loud, sitting in the café on my break — the upward spiral ended with social and political stability, and international security.

Peace. Starting from the worms.

That’s when I stopped thinking of it as a gardening problem.

VI. Getting My Hands Dirty

I went back up to Meersbrook with a plan, and the plan was: copy Lal, as best an eighteen-year-old with a bus pass and no money can.

I stopped digging. That was the hardest one, because everybody on the allotments digs. Old Terry on the next plot, who’d known Grandad for thirty years, looked at me like I’d announced I was going to grow vegetables on the moon. “You’ve got to turn it over, love,” he said. “Let the frost get at it.” I nodded politely and didn’t.

Instead I covered everything. Flattened boxes from the café went over the beds to smother the weeds, and on top I piled whatever organic matter I could get: council green-waste compost, leaf mould from a woman down the road, buckets of coffee grounds from four cafés on Division Street, horse muck from a stables past Ringinglow, fetched in feed sacks on the bus until the driver gave me a look.

I realised later that this was Lal’s idea of recycling organic by-products, including urban waste, back into the soil. A city throws away a huge amount of carbon every day. I was just catching a tiny bit of it before it went to landfill and putting it where it belonged.

In autumn, instead of leaving beds bare, I sowed cover crops: field beans, phacelia, crimson clover. I learned the beans and clover pull nitrogen out of the air and store it in their roots. I learned that roots are how a plant pumps carbon down into the ground, like a straw going the wrong way.

And then I waited, which is the part nobody puts in the videos.

It took a year before I noticed a difference, and it was a small one. It was the following March, and I peeled back a corner of rotted cardboard and there was a worm under it. Just one. Pink and fat and indignant at being disturbed. I’m not ashamed to say I sat down on the path and cried a bit. Terry came over to see what was wrong and I just pointed at it, and he looked at the worm, and then at me, and said, “Well. There you go then.” Which from Terry is practically a standing ovation.

By the second summer, the fork went in with the biscuit sound.

VII. The Bigger Picture

This could have stayed a nice little gardening story. I did grow courgettes. Far too many.

But I couldn’t stop thinking about the scale of it.

I’d spent two years and an embarrassing amount of coffee grounds bringing back about two hundred and fifty square metres of soil in the middle of a city. Meanwhile, Lal’s paper talked about a third of the world’s land. It talked about a billion smallholder farmers cultivating less than two hectares each, many in places where the soil is degrading fastest and people have the least money to fix it. It talked about the world needing to grow around seventy per cent more food between 2005 and 2050, on the soil we’ve got, which is getting worse.

He wrote that restoring soil is a societal, national and international task. It can’t just be people like me with cardboard. It needs scientists measuring what works, farmers paid to look after the ground rather than strip it, and people who understand both the science and the humans who have to put it into practice.

And it struck me, one evening sitting on Grandad’s bench with the whole of Sheffield going gold below me, that this city knows something about that.

Sheffield was built on what came out of the ground. Coal, iron, then steel — knives and rails and the stainless steel in half the kitchens of the world. We were brilliant at it. We were also brilliant at the damage: black air, poisoned rivers, moors scarred by our soot. The gullies on Kinder are partly our handwriting.

Somebody in this city ought to be good at putting things back.

VIII. The Decision

The next September I went back to college — an Access to Higher Education diploma in science, evenings, so I could keep my shifts. I was the youngest by ten years, surrounded by nurses retraining and dads made redundant, and they were the best people I’ve ever studied with. Everybody was there because they wanted something.

Chemistry nearly killed me. Nobody at school had ever told me what it was for. But now I knew. Cation exchange capacity, which had been one of those terrifying phrases in Lal’s paper, turned out to be about how well soil holds on to nutrients, like a magnet holding pins. Every single equation had a worm on the end of it, somewhere.

I’ve got my place at university: environmental science, with as much soil as they’ll let me take. The plan — written down, stuck inside my wardrobe door — is a master’s in soil science after that and work on restoration. Peatland, farmland, urban land, I don’t mind which. Anywhere the spiral’s going the wrong way.

When I told Mum, she said, “Soil? You want to study mud?”

And I said yes. I said it’s the most important mud in the world, because it’s the only mud we’ve got. I said it feeds us and cleans our water and holds the carbon and stops the floods, and we’ve been treating it like dirt. I said Grandad knew. He couldn’t have told you about soil organic carbon pools or ecosystem services, but he knew. He used to say you look after the ground and the ground looks after you. Lal wrote a whole scientific paper that basically says the same thing, with numbers.

She went quiet for a bit, and then she said, “He’d be dead proud of you, you know.”

I know.

IX. What I Want You to Know

I’m writing this down because I’m twenty now, I start in September, and some days it all still feels impossibly big.

Some days it’s another flood, another drought, another conflict where the background reason — never the headline — is land that can’t feed the people on it. I look at a third of the world’s land, then at my one plot, and the maths doesn’t add up.

But here’s what I’ve learned, and I want to say it firmly, because I wish someone had said it to me at eighteen when I couldn’t see the point of anything.

The spiral works both ways. That’s not wishful thinking; it’s the science. The same feedback that drags soil down can lift it back up. Cover the ground. Feed it. Leave the life in it alone to do its work. Be patient. It’s slow at the start, so slow you’ll wonder if anything’s happening at all. And then one day you lift a bit of cardboard and there’s a worm.

That’s how it works with people too, I think. One person starts. Then Terry on the next plot, who thought I was mad, quietly stops digging his onion bed and asks me where I get my coffee grounds. Then the woman with the leaf mould starts bringing it up herself. Then the allotment society asks me to give a talk, and I’m stood shaking in front of sixty people with a flipchart of spirals, and afterwards a lad my age asks if he can help on my plot because he’s thinking of studying it too.

Upward spiral.

You don’t have to be a professor from Ohio to start one. You don’t have to have a PhD or a farm or any money. You just need somewhere — a plot, a garden, a window box, a verge, a job, a vote, a voice — and the willingness to stop taking more than you give back.

The ground remembers how to heal. It just needs us to stop getting in its way, and then to get stuck in and help.

I’m going to spend my life doing that. I hope some of you will come with me.

There’s plenty of room. There’s a whole world of it, under your feet.

What the Ground Remembers: Book Club Discussion Questions

Ten questions for discussing What the Ground Remembers, a short story inspired by Rattan Lal, “Restoring Soil Quality to Mitigate Soil Degradation”, Sustainability (2015).

1. The story opens with Grandad teaching a seven-year-old to listen to soil. Why do you think the author starts with sound rather than sight? What did the “biscuit sound” and the “thud” come to mean by the end?
2. The narrator says soil is “something you inherit, and either pass on or spend.” What have you inherited — land, skills, habits, a place — that you feel responsible for passing on in better shape?
3. Rattan Lal’s downward spiral shows how one problem feeds the next. Where else in your own life, work or community have you seen a downward spiral like that? What, if anything, broke it?
4. The narrator realises that climate, floods, food prices and conflict are “all one thing” — the polycrisis — and that the thing is under our feet. Did the story change how connected these issues feel to you? Is that connection hopeful or overwhelming?
5. On Kinder Scout she sees both spirals at once: black gullies and green patches. Is there a place near you where damage and repair sit side by side? What does seeing both together do to your sense of what’s possible?
6. Sheffield is described as brilliant at taking from the ground, and at the damage that followed. Does a city, or a community, carry a responsibility for its industrial past? What would “putting things back” look like where you live?
7. Terry goes from “You’ve got to turn it over, love” to quietly asking where she gets her coffee grounds. What persuaded him — the science, the results, or the person? What tends to change your mind?
8. The narrator drops out of a business course because she “couldn’t see the point,” then thrives once chemistry has “a worm on the end of it.” What does the story suggest about purpose and learning? Has a sense of purpose ever changed how well you learned something?
9. Lal’s upward spiral ends with social and political stability and international security — “Peace. Starting from the worms.” Is that a convincing link or a leap? What would it take for soil health to be treated as seriously as other security issues?
10. The closing lines say all you need is “somewhere” — a plot, a window box, a job, a vote, a voice. What is your somewhere? Name one small, specific thing you could start this month that might begin an upward spiral.

Step 8 – Invest in Next-Generation Battery Research and Manufacturing

Establish a long-term national programme to support research, development, demonstration and domestic manufacturing of advanced battery technologies. Funding should be directed through universities, research institutes and industry partnerships, with competitive grants encouraging innovation across multiple battery chemistries rather than assuming lithium-ion will remain dominant.

Priority research areas should include:

• Sodium-ion batteries, which use abundant materials and reduce dependence on lithium and cobalt.
• Iron-air (rust) batteries for low-cost, long-duration grid storage.
• Solid-state batteries offering improved energy density and safety.
• Flow batteries for large-scale stationary storage.
• Battery recycling and critical mineral recovery technologies.

9. Evidence Base

Strategic rationale

 Battery technology remains one of the fastest-moving areas of the global energy transition. China has invested heavily in sodium-ion batteries, while research into iron-air, solid-state and flow batteries is accelerating worldwide. Because future storage technologies are uncertain, governments should avoid committing exclusively to a single chemistry and instead support a diversified research portfolio. This reduces strategic dependence on critical minerals, improves energy security and positions the UK to capture high-value manufacturing and export opportunities rather than becoming solely an importer of energy technologies. This approach aligns with the UK’s historical strengths in electrochemistry, materials science and university-led innovation

Evidence quality

☑ Practitioner case studies

☑ Grey literature

☑ Supported by extensive peer-reviewed literature

Known counter-evidence and limitations

Renewables remain weather-dependent and require complementary storage, demand management and grid reinforcement. Battery manufacture increases demand for lithium, nickel, cobalt, graphite and other minerals, creating environmental and geopolitical challenges. Long-duration seasonal storage remains an area of active development. Electricity generation alone does not eliminate emissions from aviation, shipping, heavy industry or agriculture. McKibben also notes that political resistance, permitting delays and fossil fuel lobbying remain significant barriers despite improving economics.
