Degraded Chalk Stream Environments

Debate between Lord Benyon and Oliver Heald

Monday 22nd July 2019 Commons Chamber

[Richard Benyon]

I have heard similar stories, and I do not know the circumstances of this. I wrote to the company before this debate asking for it to give its side of the argument, but I did not hear back. I am not necessarily criticising the company, as I approached it only at the end of last week.

My point is this: in our management of these rare systems, we need not just to be getting the sort of thing I was just discussing right, but to be looking at agriculture. My right hon. and learned Friend the Member for North East Hertfordshire was so correct in what he said about that. Min-till—minimum tillage—agricultural systems are vital, not least because of the worms that are allowed to prosper in the soil, which affects the permeability of that soil crust so that water goes through to the aquifer, rather than running off and taking with it a lot of the topsoil. We have a wonderful, rare and special opportunity that we can now deliver through the Agriculture Bill and the environment Bill. We are talking about changes that can make sure we are incentivising farmers and working with them right across a catchment to deliver extraordinary benefits.

[Sir Oliver Heald]

I wonder whether my right hon. Friend would wish to comment on the state of the River Kennet, which is a precious chalk stream close to him. Where does he think the Kennet is going—is it improving? Some attempts were made to improve its condition. Secondly, when he was preparing the water White Paper, I think he was hoping that it would be possible for water companies to move water more easily from one area to another. Has he any take on how that has been going?

[Richard Benyon]

One of the most enjoyable things I did in government was writing the water White Paper, and I refer my right hon. and learned Friend to page 35—I think that was the one. It showed a scene of good farming on one side of a river and bad farming on another, so that figuratively laid out before us was what we needed to see more of and what we had to stop happening. I bored my civil servants with that and I bore most of my family, with my wife referring to the River Pang as my mid-life crisis, but the River Kennet is in such trouble. A few years ago, someone spilled about an egg cup-worth of Chlorpyrifos into the system somewhere and it effectively killed several miles of life. That shows us just how extraordinarily vulnerable these ecosystems are.

We can debate great matters of state in this place, and we often do, but rivers are about people’s sense of place. As has been said, we can hold our heads high internationally if we are getting it right on rivers and we cannot if we are getting it wrong. What is shaming is that, while 85% of the chalk streams in the world are in the UK, we are getting it wrong. Wonderful things are done by organisations such as Action for the River Kennet and many of the other organisations that hon. Members in all parts of the House have talked about, but I believe the recommendations at the end of the river fly census are really worth reading.

In the context of the water framework directive, which we are transposing, correctly and with more ambition than exists in that directive as it stands, we should have a special designation for chalk streams. We should also look at the impact of phosphorus spikes and recognise that after we leave the European Union the world is our oyster and we do not have to be stuck by the same rules that govern rivers in southern France and northern Spain. This is our ecosystem, and we have to get it right.
