Degraded Chalk Stream Environments

Debate between Charles Walker and Oliver Heald

Monday 22nd July 2019 Commons Chamber

[Mr Charles Walker (Broxbourne) (Con)]

Thank you, Mr Deputy Speaker, for calling me for my Adjournment debate this evening. I am delighted that I did not try your patience with a spurious point of order, as that really would have been naughty. If I had tried your patience with a spurious point of order, it would have been on an environmental matter, and I would have just wanted to know how I could bring to the attention of this House the fact that, on Friday afternoon, the Secretary of State refused a planning application by Veolia to build a massive incinerator in my constituency. I was delighted with the refusal, and I now hope, as do all my constituents, that Veolia will give up its plans to put the incinerator in my constituency, give up trying to put one in Hertfordshire and disappear. If I had made a spurious and bogus point of order, that would have been it.

[Sir Oliver Heald (North East Hertfordshire) (Con)]

rose—

[Mr Walker]

I will give way on that point, but I would like to get to the substantive part of my speech.

[Sir Oliver Heald]

Does my hon. Friend agree that mine was not a spurious point of order? I have seven chalk streams and I want to make a speech.

[Mr Walker]

Of course, and there was nothing spurious about my delight at Veolia failing to get its application through—it was just that I wanted to bring it to the attention of a wider audience.

[Mr Walker]

I thank my right hon. Friend for alerting the House to that very important point. HS2 does pose a risk to chalk stream and riverine environments. No doubt if time allows, my right hon. Friend will bring her concerns to the attention of the House.

[Sir Oliver Heald]

I had miscounted; I have eight chalk streams in my constituency.

[Mr Walker]

My right hon. and learned Friend is such an honest and decent man. He could have misled the House that there were seven chalk streams in his area, but he has corrected the record without being summoned back—in fact there are eight.

Let us now get to the serious part of this debate, because this is a very serious matter that causes a great many colleagues on both sides of the House a huge amount of concern. The Colne; the Beane; the Mimram; the Gade; the Ver; the Chess; the Misbourne; the Wye; the Rib; the Hamble; the Bulbourne; the Quin; the Hogsmill; and the Wandle. The list could go on, but these are all chalk stream rivers that are degraded or dying around my constituency in Hertfordshire and the constituency of my right hon. Friend the Member for Chesham and Amersham (Dame Cheryl Gillan) in Buckinghamshire. This country has over 85% of the world’s chalk streams, and these streams are a unique habitat.

[Sir Oliver Heald (North East Hertfordshire) (Con)]

I pay tribute to my hon. Friend the Member for Broxbourne (Mr Walker) for his remarkable and important efforts in this area.

In my constituency, we have eight chalk streams: the Upper Rhee, the Rib, the Ash, the Quin, the Beane, the Mimram, the Lea—near Bayford, where I think my hon. Friend fishes—and the Ivel. There has been some progress with the Beane and the Mimram following the WWF campaign “Rivers on the Edge”, of which Martin Salter was a strong supporter and about which we had debates in this House. There has been a 90% reduction in abstraction at Whitehall pumping station near Watton-at-Stone, and the Fulling Mill pumping station at Welwyn Garden City was completely decommissioned; that represented some success.

As my hon. Friend said, however, the condition of the northern part of the rivers is very dry. The Upper Rhee is dry, and there is a lot of concern about the Rib in the Standon area and north of Standon. The situation is similar with the Ash and the Quin. The Beane at Walkern, north of Watton-at-Stone, is short of water. There is a campaign in the constituency of my hon. Friend the Member for Hitchin and Harpenden (Bim Afolami) about the Mimram. The Lea is low, and the Ivel springs in Baldock are so dry that people regularly write to me to express their concern.

It is worth thinking about what the unique chalk stream environment is like. My constituency has small hills, between which are the chalk streams, and they create a unique environment with unique flora and fauna. Nestling in the environment provided by these ecosystems are flowers such as saxifrage, as well as small English crustaceans and the water vole. Tewinbury nature reserve is a very good place to measure the activity of flies and little creatures, and that is a remarkable thing to do. I pay tribute to the Herts and Middlesex Wildlife Trust, which does so much to support that.

[Mr Charles Walker]

I am sorry to cut my right hon. and learned Friend off as he is paying tribute to the Herts and Middlesex Wildlife Trust, but I want to pay tribute to it as well. Jeremy Paxman recently wrote that we no longer have to clean our windscreens, because there are now no insects splattered on them. There are so few insects because our rivers—and, in our part of our world, our chalk streams—have been so degraded that insects can no longer live there. Without insects, we have no fish and no kingfishers; the whole ecosystem and food chain begin to collapse. My right hon. and learned Friend is entirely right to raise that concern.

[Sir Oliver Heald]

I am grateful to my hon. Friend for that intervention. People such as Jeremy Paxman, Feargal Sharkey—he used to be a pop star but now spends his time campaigning on this issue—Charles Rangeley-Wilson, whom my hon. Friend will know, and Martin Salter, on the angling side, are dedicating their lives to trying to make people realise that this environment is as precious as the Brazilian rainforest. We have a major part of a unique environment. The water that comes up—or should do—from the aquifer is so pure, and that is a wonderful thing.

As my hon. Friend said, the problem is a mixture of abstraction; climate change, which means that in the next 25 years we will have 20% less water than we do now; and growth in housing, which means that we are trying to do more with less water. Some of the predictions that house builders and developers make in planning applications—they say that they will be able to get people to use no more than 100 or 120 litres of water a day—are just not in the real world. In my constituency, the average is about 175 litres a day. The first thing that people do in a water-efficient house is to put in a power shower, spoiling the good work of the designers. My hon. Friend is right to say that those predictions do not add up.

Soil erosion is a big issue, on which I have campaigned with WWF; it recently ran a campaign about the subject. As has been said, one of the effects of not having strong rivers is that they end up with soil in them, particularly if farming techniques are not respectful of the surrounding environment. In an area such as ours with hills that have chalk and soil on top, it makes a lot of sense to go for no-till farming, so that the soil is not blown off the tops of hills and into rivers. There is a lot that can be done.

I pay tribute to the societies in my constituency—including the Friends of the Mimram, the River Beane Restoration Association and the new organisation for the River Rib—which are trying hard to highlight the plight of the rivers. Despite the campaigns, the work that has been done and the reports in this House going back some years, we have made only a little progress against a background of deterioration. It is a question of one step forward and two steps back. I am grateful to my hon. Friend for raising this issue and giving us a chance to highlight the importance of this environment and ecoculture. Much more needs to be done.

On the Abingdon reservoir, I came into this House in 1992, and Thames Water was lobbying us then about building the Abingdon reservoir. Here we are 27 years later, and it has still not been built; it is still a few years away. We need to get on and do this. The background is against us, and action is needed.
