What the Data Reveals About Farmers Who Adapt Early

Two Ways of Reading the Land

Michael O’Brien had been farming the same 65 hectares in County Tipperary since 1987. He knew the land the way you know a person you have lived with for decades knowing about its moods, its rhythms, its stubbornness in wet April, its generosity in a good June.

His daughter Mai had grown up on the farm, left for university, studied environmental science, and then come back. Not out of obligation. Out of love for the question that had started nagging her somewhere around 2018, the year the summer turned to dust and the grass simply… stopped.

She had come back with data.

Michael had never stopped believing in instinct. Mai believed in instinct too which she called “tacit knowledge” now, which made Michael laugh, but she also believed that instinct alone was no longer enough. The climate was changing faster than intuition could track.

The tension between them was not hostility. It was the productive friction of two people who loved the same thing and were arguing about how best to protect it.

This is the story of what happened when data and experience finally sat down together at the same kitchen table.

The Year the Grass Stopped Growing

It began, as many things do in Irish farming, with weather.

The winter of 2017–18 had been long and unusually cold. Then spring arrived late, wet, and unforgiving. Then summer arrived — and brought nothing with it. No rain. Bone-dry soil. Fields that turned yellow by July and brittle by August.

For Michael, 2018 was the hardest year in three decades. His silage stocks, already strained from the long winter, ran short. He had to buy expensive feed from as far away as France. His feed bill nearly doubled. The grass that usually supported his herd simply wasn’t there.

Michael absorbed the loss. Filed it away. Told himself it was a once-in-a-generation event.

Mai wasn’t so sure.

What the Models Were Saying

The projections on Mai’s screen came from Teagasc’s AgriAdapt programme, which uses national climate data from Met Éireann’s TRANSLATE project to model how grass growth, crop yields, and forestry productivity will change across Ireland. ↗ AgriAdapt, Teagasc 2026

This was the central paradox. More grass overall — but less when you need it most. Summer droughts such as 2018 are expected to increase in frequency. Grass growth is predicted to decrease in the months of July to September for the midlands and east coast. ↗ Farmers Journal / Teagasc Signpost Programme, 2024

It was a simple question. But it cracked something open — because Michael, until that moment, had been asking the wrong one. He had been asking: will this happen again? He had been waiting for certainty before he changed anything.

Mai had been asking: what do I do now, given that it probably will?

Risk Salience: When the Abstract Becomes Personal

This difference in questions is, it turns out, one of the most studied phenomena in behavioural science. It has a name: risk salience — how vivid, immediate, and personally relevant a risk feels. And it is one of the strongest predictors of whether a farmer will adapt early or late.

The Teagasc Farm Resilience Project found that Irish farmers increasingly view extreme weather events as a fundamental shift, not simply normal variation. ↗ Teagasc Farm Resilience Project, 2025

For Michael, the 2018 drought had done something important: it had made the abstract personal. It had given the climate models a face. What he hadn’t yet done was act on them.

The Knowing–Doing Gap

In December 2022, four years after the drought, Mai found a paper that articulated what had been happening on their farm. A systematic review in Mitigation and Adaptation Strategies for Global Change (2022) found that techno-informational, economic, and environmental barriers were strongly and inversely correlated with adoption of adaptation measures. Policies must consider measures tailored to specific farming systems to most effectively alleviate barriers and promote resilience. ↗ Bryan et al., Springer 2022

Knowing you need to change is not the same as knowing how to change, or being able to.

Mai wrote that down. Pride + fear of regret = paralysis. She circled it. The research literature had a name for this: the intention–behaviour gap. And it had a solution — though not the obvious one.

What Early Adapters Actually Do Differently

It was a cold February 2023 evening when Mai spread her research across the kitchen table. She wanted to know: what did early adapters do differently? The evidence was surprisingly consistent across contexts.

5.1 — They Reseed Earlier, and with More Species

Multi-species swards — mixing grasses, legumes, and deep-rooted herbs like plantain and chicory — had been discussed at every Teagasc event Mai had attended. The data was unambiguous.

Research from Trinity College Dublin found that six-species swards outperformed perennial ryegrass monocultures and were considerably more resistant to drought. The most productive combinations included species from three functional groups: grasses, legumes, and herbs. With legume proportions between 30–70%, yields exceeded the best monoculture. ↗ Trinity College Dublin

5.2 — They Build Buffers Before They Need Them

Farmers who had adapted most successfully built fodder reserves for longer winter periods and potential spring/summer droughts, and invested in sufficient housing space and slurry storage. ↗ Teagasc Farm Resilience, 2025

This wasn’t dramatic. It was unglamorous. The difference between a farmer who has two extra weeks of silage in March and one who doesn’t — that’s the margin. In 2018, that margin was worth thousands of euro.

5.3 — They Treat Soil as Investment, Not Cost

Cover cropping, conservation tillage, and organic manures improve soil organic content, enhance water retention, and make crops more resilient to both droughts and floods. ↗ Signpost Programme, 2024

Soil testing and liming can boost grass growth by up to 1.5 tonnes of dry matter per hectare. On a 65-hectare farm, that’s roughly 97 additional tonnes of dry matter per year — the equivalent of a significant reduction in bought-in feed.

5.4 — They Stay Connected

The FAO found that early adapters are consistently more connected to advisory services, peer learning networks, and digital forecasting tools. The Teagasc Farm Resilience Project echoed this: resilience grows when informal and formal knowledge are integrated. ↗ EVS Institute / FAO synthesis, 2025

The Income Story

Mai had saved the income data for last, knowing it was what Michael would ultimately ask about. The pattern was clear.

In 2018, system-wide averages masked enormous variance. Farmers who had built silage buffers, diversified sward species, and improved soil health before 2018 still suffered — but their losses were 8–12% rather than 25–30%. Some broke roughly even. The adaptation wasn’t a guarantee. It was an insurance policy.

The global evidence reinforces the point. An investment of just US$800 million in early warning systems across developing countries could prevent annual losses of $3–$16 billion. In weather-sensitive agriculture, improved climate advisory services could unlock over $160 billion annually in global economic gains. ↗ UNDP via EVS Institute, 2025

The Walk That Made It Real

It was a Saturday morning in March 2024, and they were walking the fields before breakfast — a habit Michael had kept since his own father had shown him the land the same way, before words, through walking.

Mai was talking about a concept she’d been reading about: implementation intentions. The research, developed by psychologist Peter Gollwitzer in the 1990s, shows that the gap between intention and action collapses when people specify when, where, and how they will act — not just that they will.

She didn’t say anything else. She had learned, from the behavioural science literature and from living with her father, that sometimes the most powerful thing you can do is leave a gap in a conversation.

Michael stood and looked at the paddock. The grass was thin in the middle. Two years of thinking about it hadn’t changed that.

It wasn’t a dramatic moment. There was no music. The sun didn’t break through the clouds. But something had shifted.

The Paddock That Changed in Autumn

October 2024. Michael and his contractor reseeded paddocks 4 and 7 with a six-species mix: perennial ryegrass, white clover, red clover, plantain, chicory, and Timothy grass. The mix Jim had used. The mix the research had pointed to.

He applied for the Department of Agriculture’s Multi-Species Sward Measure — which, since 2022, has been offering financial support for exactly this kind of establishment. The government scheme aims to incentivise farmers to establish multi-species swards, reduce reliance on nitrogen fertilisers, and contribute to the Climate Action Plan 2023. ↗ Gov.ie, Multi-Species Sward Measure 2024

The sward was slow to establish through November. Michael checked it twice a week and said very little.

In February, the first true leaves came through. Plantain rosettes. Clover trifoliates. The fine filaments of chicory.

He texted Mai a photo.

She was in Dublin, preparing a research presentation. She looked at the photo for a long time.

The paddock looked unremarkable. Pale winter green. A bit muddy at the gate.

But she knew what it meant: a small bet on the future, placed before the crisis arrived. A narrowing of the gap between knowing and doing.
