River Habitats: Protection and Restoration

Rachel Gilmour Excerpts

[Rachel Gilmour (Tiverton and Minehead) (LD)]

Thank you, Ms Butler. It is a pleasure to serve under you. I thank the hon. Member for Bournemouth East (Tom Hayes) for his kind words. I should start by declaring a couple of interests: before I came to Parliament I was head of strategy for the Environment Agency, specialising in water flooding and the water framework directive. Before that, I was the director of communications for the National Farmers’ Union—the first woman to sit on their board in 100 years. Despite my nerves about my first outing, I feel calmly confident that I have got a grip on things.

I congratulate my colleague from the Public Accounts Committee, the hon. Member for South Dorset (Lloyd Hatton), on securing the debate. I was particularly interested in his comments about the beavers on the Isle of Purbeck, because we have had similar issues in the constituency of my hon. Friend the Member for North Devon (Ian Roome). I was touched to hear the hon. Member for North Herefordshire (Dr Chowns) talk about the rivers of this country being like veins in a body, echoed by the hon. Member for Brent West (Barry Gardiner). The edifying and incisive observations in the debate show that this is clearly a matter close to all our hearts, whatever political party we come from—although it matters to a couple of us more than others.

Across the country, we are witnessing storms of increasing frequency and ferocity, and it would be remiss of me not to acknowledge the devastating flooding that has swept across my part of the world in the south- west in recent days. Events that were once expected every 300 years and then once every 100 years now seem to strike with alarming regularity. Our rivers, which are among Britain’s most precious wildlife habitats, are bearing the brunt of environmental decline. According to the Rivers Trust, and it is not the first time this has been mentioned, not a single English river is in “good chemical health” and only 15% are considered to be in good ecological condition. That is a sobering reality. Freshwater ecosystems are collapsing and this country now has some of the unhealthiest rivers in Europe. The species that depend on the waterways, from fish to invertebrates to birds, are struggling to survive. Our rivers desperately need a reprieve.

England is home to 85% of the world’s chalk streams: rare, crystal-clear, ecologically distinctive waterways found almost nowhere else on earth. Part of the challenge lies in the withdrawal of the Environment Agency from stewardship of many of our rivers. For years, maintenance of watercourses has been inadequate; now, with the EA stepping back for whatever reason in further parts of the country, including my own, the burden of looking after the waterways has become heavier still.

We must recognise that farmers are on the frontline of environmental challenges and that the relationship between land and water has changed significantly and dramatically over the past century, encapsulated in the European water framework directive, which is not a complicated piece of legislation. That is why my party consistently emphasises the vital role of farmers as custodians of the natural world. They work tirelessly to reduce run-off and protect habitats, but they need support. Agricultural run-off, slurry, fertilisers and other such chemical cocktails continue to enter our waterways. That has patently been exacerbated, given the recent devastation caused by Storm Chandra in which huge swathes of the west country were submerged, washing pollutants into rivers and compounding the ecological damage.

It will come as a surprise to no one that blame must be laid at the feet of water and sewage companies and their conduct. I had a meeting with South West Water on Monday, and it was obvious that their obscene greed and incompetence had inflicted immense harm on river habitats across the country and, indeed on my constituents in Bampton. Grotesque quantities of sewage have been allowed to spew into British waterways and there have been discharges on an industrial scale, with catastrophic consequences for aquatic life. It is an absolute insult; heads, I fear, must roll. The Liberal Democrats are sadly disappointed by the Government’s water White Paper, as it falls short of the promise to bring about fundamental regulatory reform. We believe that the current model of private ownership has utterly failed. Frankly, only a complete overhaul will do.

The Liberal Democrats would introduce a system in which water companies are mutually owned by customers and run professionally in the public interest. We also call on the Government to finally end the scandalous sewage cover-up by forcing those crooked water companies to publish the volume of dumped sewage and not just the duration of spills. After all, sunlight is the best disinfectant. The Government’s plans—I am really sad about this because I am usually on side—do not cut the mustard. The decision to abolish Ofwat is welcome, but it is only the first step. We will continue to press the Government to establish a new, robust regulator, with real teeth and real accountability, as a matter of urgency.

Turning to other causes of harm, water abstraction has risen sharply, reducing river flows and placing ecosystems under severe stress. Many rivers now run perilously low, especially during dry periods. Moreover, centuries of physical modification—straightening, damming, embanking, diverting and disconnecting—has fundamentally altered the natural character of our rivers. Those changes have inevitably disrupted fish migratory patterns, fragmented habitat connectivity and in turn diminished resilience to climate change. A river that cannot move, meander or naturally flood is a river that simply cannot thrive. Restoration efforts should focus on allowing our rivers to re-wiggle—I love that word, which means to return to their natural meanders—reconnecting them with flood plains, and rebuilding the diverse physical habitats that sustain life. In many cases, the best thing that we can do is to step back and let mother nature take her course—in essence, to rewild herself. That would include removing barriers such as weirs and small dams to aid fish passages, creating riffles, pools, wetlands and woody debris to enhance biodiversity, establishing nature-rich corridors along river banks and expanding natural flood management systems.

Interventions such as these are not just environmentally beneficial; there is a major economic element to this. Healthy waterways provide essential services to all our systems. They are our lifeblood.
