Lords ChamberMy Lords, we find that we form some unusual alliances in your Lordships’ House, especially in relation to protecting our environment. On this topic, I was very happy to put my name to Amendment 102 in the names of the noble Viscount, Lord Trenchard, the noble Earl, Lord Caithness, and the noble Baroness, Lady Bakewell of Hardington Mandeville. The reason I did that was that I am lucky enough to have spent my life living in the wonderful county of Hertfordshire. For those of you who are not aware, Hertfordshire contains over 20% of the world’s unique and special, natural and precious chalk streams. The noble Viscount has already explained that this country is the custodian of the vast majority of this precious natural resource—more than 85%. To have 20% of that in my county is a real reason for doing all that I can to ensure that they are protected.
From the Rivers Chess and Colne in the west of Hertfordshire and the River Beane, which runs alongside my town, to the Rivers Lea, Stort and Ash in the south and east of the county, along with many others, we are blessed with what should be vital water resources, providing habitats for a huge diversity of species, from damselfly to salmon. Sadly, as we have heard, they are under increasing pressure from overextraction and pollution and, while progress is being made through the catchment-based approach mentioned by the noble Viscount, Lord Trenchard, they are still struggling and under pressure. We need to improve their health and focus on that through the chalk stream strategy. There is still much more to be done.
I am most grateful to the Herts and Middlesex Wildlife Trust, which does so much work in this area and has been incredibly helpful in providing information for me. Our precious monuments and ancient buildings have huge protection in the planning system through the mechanism of listing, but we do not seem to take these precious natural resources as seriously in this regard. I support the aims of the amendment in attempting to do that by ensuring that any development in the area of chalk streams explicitly considers the impact on them and sets out what mitigations will be needed. If our chalk streams were buildings, they would be UNESCO heritage sites. Let us protect them as though they were.
One of the problems that I raised during our debate on 18 May in Committee was the problem of surface water run-off from farms and roads, which was causing problems for our rivers. I am extremely grateful to and would like to thank my noble friend the Minister for the letter that he sent me on 23 June, in which he commented a bit more on the points that I raised. The interesting thing about that letter was his comment on the surface run-off from roads. He said that Defra was
“working with the Department for Transport to reduce the impact of the strategic road network and roads managed by local highways authorities on water bodies”.
It just shows what an important cross-government issue this is.
The difficulty that my noble friend has is that he has to work at one remove from the local authorities. The reason I stress the local authorities is that the next day, on 19 May, I was on the River Piddle, a lovely chalk stream, and at 3.30 pm the river was gin clear—it was what a chalk stream should be. We had quite a good thunderstorm and within an hour that river was chocolate brown; it was full of silt and run-off, and the roads were under water. There was run-off from the farmland adjacent to the river—the whole aquatic environment of the river was affected by that thunder- storm; it was a short-term disaster for the river, created by human behaviour. Something similar happened to us humans when we had the smog in the early 1950s. We tackled that problem; it was a manmade problem and we tackled it with the Clean Air Act. It is equally important that we now tackle the problems facing our rivers. It will take a major effort by the Government and across government to do that.
All our rivers are important, but why are the chalk streams just that bit more important? It is worth reiterating that 85% of the world’s chalk streams are in England; they are our equivalent of the rainforests. We have a special responsibility to those rivers, and if we do not give a lead to the rest of the world on such an important issue, we will not be doing nature justice.
There are three key indicators of the ecological health of rivers: water quality, water quantity and the physical habitat. The key to getting all of those right is management. The Government will need every single tool in the toolbox and every policy to be able to take the necessary action to fight off the vested challenges from all quarters that they will need to do to establish chalk streams to the standard that we expect and fulfil the one big wish, so rightly mentioned by my noble friend Lord Trenchard.
The Bill is about regenerative action and levelling up, and it is intended to give places a sense of identity. As my noble friend Lord Trenchard said, many of the rivers flow through towns as well as the countryside. The restoration of the rivers could bring huge opportunities and benefits to those towns and to the countryside for both nature and humans. If we do not take this opportunity, we will be letting nature and ourselves down.
