I beg to move, That this House has considered water scarcity.  It is a pleasure to serve under your chairmanship, Mr Stuart. In a country where we always complain about the rain, we have somehow contrived to have a water shortage. I am reminded of the words of the poet Samuel Taylor Coleridge: “Water, water, everywhere But not a drop to drink” But the honest truth is that it really does not rain like it used to. This year, the UK experienced the hottest and driest spring on record. Farmers endured a devastatingly poor harvest and lost £800 million to drought. Over the long term, the prediction is for ever greater weather volatility. In October—yes, October—my home county of Sussex was placed under drought measures, as Ardingly reservoir fell below 30% capacity, compared with the seasonal average of 76%, and there are greater challenges to come. By 2050, the UK population is forecast to rise by 10 million. Further demand from data centres, renewable energy infrastructure and new industry is also rising quickly, but is yet to be factored in to demand. The National Infrastructure Commission projects a national supply-demand deficit approaching 5 billion litres a day by 2050 unless action is taken. That is a gap equivalent to the daily water use of more than 30 million people, and that does not even include commercial demands, such as farming, manufacturing, horticulture or business activity. For something that has become so precious, we are remarkably careless about it. Fully one fifth of the water that enters the system is lost before it reaches even a single property because of leaky pipes. River abstraction now accounts for 61% of all environmental water abstraction, up from around 40% in the early 2000s. This is clearly contributing to severe pressure on our waterways, especially chalk streams, one of Britain’s most unique ecosystems.
