The Earl of Caithness (Con)

My Lords, I support my noble friend Lady Coffey’s Amendment 341, which refers to ponds. She was quite right to mention floods and drought. I would just like to follow up on that and remind your Lordships what happens with flood and drought. It is the loss of topsoil that is so damaging to farms. If one has ponds, one can collect the topsoil before it does further damage. It does further damage in two ways. First, if you are near a chalk stream, you get silt going into the chalk stream, which is destroying the environment of the chalk stream. A chalk stream should not have silt in it. I remember speaking in the House last year, I think, about chalk streams and how a sudden thunderstorm had turned a chalk stream from being a crystal gin-clear stream, as it should have been, into a dirty brown river, and the damage that that was doing to the environment of the chalk stream. Secondly, if the water catchment area goes into a reservoir, a huge amount of topsoil is filling up reservoirs. One might look at a reservoir once it is full of water and think, “Gosh, that’s a really big reservoir”, but one finds that actually a third of it is silted up from years of run-off from the adjoining land. Having ponds that stop that must be a good idea. They can easily be sited in areas of unproductive farmland. I also notice the interpretation of a pond. My noble friend was absolutely right to mention that this should be permanent or seasonal. With the recent flooding we have had, there has been some terrible damage to farmland, sometimes where a pond would have stopped the damage. It would not be a permanent pond, it would be a seasonal pond, but it would help to reduce the damage to farmland from the run-off of the heavy rain. I hope that the Government will look at that amendment particularly carefully.
