As we drove down to Pembrokeshire in early February, there was a feeling of hopefulness in the air, with the first bright yellow daffodils popping up along the verges and the sun reflecting off a wild, rough sea. A walk on a pebbly Welsh beach was certainly inviting, but we weren’t just there for the scenery. We were there to see if the ambitious goals of nutrient rebalancing and regenerative farming actually hold water when they meet the daily reality of a working dairy farm.
A River Under Pressure
The Cleddau is at the heart of Pembrokeshire’s landscape, with the Eastern and Western Cleddau rivers flowing together into a deep-water estuary. It is a vital part of the area, but is currently facing significant pressure. Agricultural pollution remains one of the most significant pressures on rivers across the UK, and the Cleddau is no exception. Nutrient runoff from fertilisers and manure can enter these waterways, contributing to ecological damage and declining water quality.
We went specifically to speak about nutrient pollution in the catchment and how farmers are already making practical changes in farm management, alongside support from supply chains, to make a difference, as well as what more needs to be done. On the ground, this looks like a shift in how the land and herds are managed. Perhaps most importantly, we saw how “river-friendly” farming focuses on grazing management. By moving away from traditional intensive methods toward systems like conservation grazing, farmers can better protect the soil and the water that runs through it.
Our trip was organised by Ric Cooper, the local linchpin and lead of The Cleddau Project. Ric is the kind of campaigner who is able to navigate complex nutrient data one minute, coordinate citizen science volunteers the next, and then talk practicalities with farmers. Because he is such a trusted local voice, he was able to introduce us to a wide variety of perspectives across the catchment.
From Indoor Housing to Open Pasture
Through Ric’s introductions, we met with local farmers Mike Smith and Andrew Rees to learn firsthand how they are implementing practical measures to reduce their environmental impact. Both are part of the First Milk cooperative, a British farmer-owned dairy co-op focused on regenerative, grazing-based systems. First Milk requires its members to provide at least 120 days of pasture access per year, advocating for grazing as a vital alternative to intensive indoor housing.
The benefits of this approach are rooted in the local nutrient cycle. In indoor systems, cows are often fed imported feed, rich in phosphates and nitrates that were grown elsewhere, sometimes even in another country. This introduces “new” nutrients into the local environment. In contrast, when cows graze on pasture, they are consuming nutrients already present in the local soil. This means that when the cows produce slurry, the nutrients within it are local to that specific area. By spreading this slurry back onto the same farmland, the nutrients remain balanced with the land rather than overwhelming it. This closed-loop system is essential for protecting our rivers from the nutrient runoff that leads to eutrophication – where excess nutrients cause algal blooms that choke the river of oxygen – damaging the ecology of the river.
This transition toward “river-friendly” farming isn’t limited to grazing alone. We discussed a variety of other approaches, such as improved nutrient management and more precise manure and fertiliser control, which can significantly reduce the risk of runoff into the Cleddau. At Moor Farm, Andrew has turned the traditional high-input model on its head by significantly reducing fertilisers and chemicals. He believes that these changes aren’t just an environmental “nice-to-have” lower inputs can actually maintain or even improve profit margins while restoring the health of the land.
Collaboration Across the Supply Chain
Ric also introduced us to Christopher and Emma at Puffin Produce, the largest supplier of Welsh fresh produce and partial owners of the Pembrokeshire Creamery. This dual role puts them in a unique position to influence both the fields and the dairies. They are leveraging the Landscape Enterprise Networks (LENs) to bridge the gap between commercial supply and environmental health.
Through this network, they co-fund nature-based solutions that are designed by the farmers themselves. It’s a bespoke approach: rather than a top-down mandate, it empowers each farm business to propose the specific regenerative practices that will best protect that local area’s unique geography.
The Big Picture: A Future for the Cleddau
As we left Pembrokeshire, it was clear that protecting rivers requires coordinated action across the entire food and farming system, from the farmers in the pasture to the cooperatives, retailers, regulators, and policymakers. Encouragingly, our conversations with leaders like Andrew Rees, Mike Smith, and the team at First Milk showed that many farmers are already working to be part of the solution.
However, scaling these efforts will require more than just environmental ambition. We learned that the transition to regenerative farming is often seen as a risk that takes several years to realise. To succeed, we must shift the frame, to show that “river-friendly” farming can be economically viable.
The commitment we saw from Puffin Produce, First Milk, and Ric Cooper’s citizen science network proves that when local trust and supply chain support align, real change is possible. Supporting and scaling these collective efforts will be essential to restoring and safeguarding the health of our rivers for future generations.
