I, too, read the Thames Water briefing that was sent out at the back end of last week. It said—I think the hon. Gentleman mentioned these figures, which caught my eye—that accounting for climate change, population growth and environmental regulations, there will be a daily shortfall of some 350 million litres a day by 2045, and that will, in turn, double in the following 50 years. So this is an environmental catastrophe that is being played out day to day across the country.

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.

I will keep my comments brief. It is interesting that we often talk about the environmental crisis and climate emergency in various other manifestations, but we rarely talk about the threat that water shortages pose to our existence. I think we agree that climate change, as we face it, threatens us in many ways. We are experiencing a changing climate and changing weather events of a new severity. We grew up with wet Aprils, and perhaps even wet Mays, but we no longer experience them.

The hon. Member for Dagenham and Rainham (Jon Cruddas) spoke about the Thames Water briefing that was put out. He said he was struck by the predicted shortfall of 350 million litres a day between the amount of water available and the amount we will need by 2045. Population growth, climate change and environmental regulations will dramatically affect our demand and need for water. I echo the call made by the hon. Member for Warwick and Leamington, because unless we build in safeguards and build in the reuse of water, we are going to find ourselves in a desert and in a drought like no drought we have ever seen. We take water for granted in this country; it is such a shame that we have that attitude. We will have to change it if we are going to preserve our environment, particularly our chalk streams.

This excellent report, which we have all had the opportunity to read, contains a number of recommendations and actions. I will not read them out, but I recommend that the Minister read them carefully and study what could be an important way forward in giving vital protections to this part of our environment. It is unique, and the status of these chalk streams is important not just to the environment in the United Kingdom, but to the world. Once we have lost them, we will never ever get them back. If there is a climate change crisis, there is certainly an even bigger crisis in the state of our chalk streams.

The hon. Gentleman, I and many others in the Chamber agree on and appreciate the wonderful work of the National Farmers Union and the Northern Irish Ulster Farmers Union on habitat, climate change, their commitment to carbon zero and many things. Should we not have on record in this debate the good work of the NFU and farmers who are committed to changes to make things better and preserve the environment for the future, which he and I believe in?

I entirely agree with my hon. Friend. Perhaps I can conclude by entirely endorsing what the farming unions of these islands have agreed, and Minette Batters’ very brave and clear statement about moving to net zero considerably before the rest of the country and making sure that agriculture fulfils its responsibilities. Part of that is about looking at catchments and saying, “How can we lock up more carbon?” The clear, easy way of doing that is to have a more broken-up mosaic of land use, which includes grass as part of the rotations. With encouragement for minimum tillage, not only can we start to see more carbon being locked up, but our rivers will be protected from many of the things that are causing problems at the moment.

20:46 The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Dr Thérèse Coffey)

I have had three years in this very special role as Minister for the environment. I am very fortunate that, by and large, neither an official drought nor an official flood has been declared. I am conscious of the work of my hon. Friend the Member for Boston and Skegness (Matt Warman) on what happened recently in Wainfleet; I visited his constituency to discuss floods. The issues that have been raised about drought worry many of our farmers around the country, who are also considering the impacts of abstraction reform. I am very conscious that my constituency of Suffolk Coastal is one of the driest in the country. That said, at the Latitude festival, which was held this weekend in my constituency, there was a hailstorm, in the middle of July. Who would have thought that in Suffolk, when we are all having a heatwave? That just shows how important it is that we look after the habitat that is special to our country and to our world, while the impacts of climate change do what they do.

I return to the main topic of the debate. While chalk streams contribute to our health and wellbeing, they are principally unique habitats supporting a diverse range of invertebrate and fish species and have long been held in high regard for the quality of the fisheries they support. Only 200 chalk rivers are known globally, and it is amazing to think that 85% of them are found in the UK in the southern and eastern parts of England. It is well recognised, however, that our water resources are under pressure and that this pressure is growing as the climate changes and the demand for water increases from a growing population and greater housing need. As my hon. Friend outlined, our chalk streams are facing an unprecedented challenge, having been heavily affected by human activity, including abstraction, pollution and historic modification.
