World Water Day: Why Regenerative Farming Is Essential for Clean Rivers

Water underpins everything in agriculture. Every field. Every animal. Every crop. Without clean water, there is no food system worth defending.

World Water Day should not be a token gesture. It should prompt an honest examination of river pollution in the UK  and how farming systems either protect water quality or degrade it.

The State of Rivers in England

In England, only around 14% of rivers currently meet good ecological status. Agricultural runoff is one of the primary reasons they fail.

Soil, fertiliser and slurry wash into waterways. Nitrogen and phosphorus overload freshwater systems. Sediment smothers fish spawning grounds. Oxygen levels drop. Aquatic wildlife declines.

This is not an attack on farmers. It is a recognition that, for decades, agricultural policy has prioritised output over ecology.

How Soil Erosion Pollutes Rivers

When soil is left bare or compacted, rainfall cannot infiltrate. Instead, water runs off the surface, carrying topsoil with it.

The UK loses millions of tonnes of soil every year through erosion. That soil contains nutrients, carbon and microbial life. Once it enters rivers, it becomes pollution.

Sediment clouds water, blocks light, and disrupts aquatic ecosystems. Nutrient-rich runoff accelerates eutrophication. The result is degraded water quality and biodiversity loss.

Why Soil Health Determines Water Health

Healthy soil behaves differently.

Soil rich in organic matter improves water infiltration and retention. Structure strengthens. Pore spaces increase. Earthworm channels form. Roots penetrate deeper.

Research consistently shows that increasing soil organic matter enhances water-holding capacity and reduces surface runoff. That translates to:

• Reduced flood risk downstream

• Greater drought resilience

• Lower nutrient leaching

• Improved river water quality

Soil health and water health are inseparable.

How Regenerative Farming Protects Water Quality

Regenerative farming systems focus on restoring ecological function. Core principles include:

• Keeping soil covered year-round

• Maintaining living roots in the ground

• Integrating livestock effectively

• Increasing biodiversity

Diverse pastures containing grasses, legumes and herbs develop stronger root networks. Holistic planned grazing moves livestock frequently, allowing land to recover and preventing overcompaction. Manure is distributed naturally across fields rather than concentrated in slurry lagoons.

These practices reduce agricultural runoff and improve nutrient cycling.

Nitrogen Fertiliser, Runoff and Public Cost

Conventional farming systems often depend heavily on synthetic nitrogen fertiliser. Globally, a significant proportion of applied nitrogen is not absorbed by crops.

Instead, it leaches into groundwater or runs into rivers.

Water companies then spend substantial sums removing nitrates to make drinking water safe. Those costs are passed on to the public.

When water systems are degraded, society pays twice — first through environmental damage, then through treatment and remediation.

Flooding, Drought and Catchment Resilience

The UK is experiencing more extreme weather patterns. Intense rainfall events strike compacted soils and move rapidly through catchments. Rivers rise quickly. Flooding follows.

During dry periods, degraded soils struggle to retain moisture.

Regenerative land management improves infiltration rates, reduces peak flood flows and strengthens long-term water stability across landscapes.

Upstream decisions affect downstream communities.

Water Quality, Food Quality and Human Health

Water quality is not separate from human health.

Contaminated water carries risks. Depleted soils reduce ecosystem resilience. Food grown in biologically active soils differs nutritionally from food grown in degraded systems.

Soil health, water health and human health form a connected system.

Why We Defend Regenerative Agriculture

If we want clean rivers, we must farm in ways that protect them.

Water flows through agriculture. The choice is whether farming pollutes that flow or purifies it.

We choose the latter.
