My Lords, I congratulate my colleagues on Sub-Committee D for producing this report, especially those in the background who actually wrote most of it. I also thank my noble friend Lord Carter of Coles for—if I can put it this way—his robust chairmanship. The title of the report is An Indispensable Resource, but like so many other environmental goods, water is often treated as though there is an indefinite amount to go round. As climate change advances, it is likely to become a very scarce resource indeed, especially on a global level, although at some times and in some areas there will be too much of it as well. In other words, a mixture of droughts and floods—as other noble Lords have said—is a vision of our future.

In the UK over the past several years, we have seen just such a mixture. The same is also true at a somewhat more violent level on the continent, for example prolonged droughts interspersed with violent storms and flooding in the Mediterranean area. There was also an unprecedented flash flood in Copenhagen in July 2011, which completely paralysed the city. A recent daunting report on these issues was produced by the European Environment Agency only about a week ago. This showed that the past 10 years were the warmest on record in Europe—again the shape of things to come. I have four questions for the Minister. I shall make some comments and ask for his responses on the report, the Government’s response and the Commission’s blueprint.

First, as elsewhere, climate change will have a differential impact in the UK affecting different areas in opposing ways. Some areas will not have enough water and, as I said before, others will have too much. Water will have to be shipped around the country and new flood defences built. My question for the Minister is how can a national programme be developed, given the level of the industry’s privatisation in England and Wales? As the report makes clear, the English system is more or less unique in the EU in terms of the level of privatisation. Can that be reconciled with adequate overall planning for the future? Secondly, the Government’s response on water savings seems rather thin and inadequate. The report quotes figures of 20% of water wasted across the EU due to inefficiencies. New infrastructure will be needed, but we have to consider other strategic initiatives too. One is inducing culture change in the use of water by business and consumers. As someone who has worked on the many aspects of the field of reducing carbon emissions, it has proved difficult to change people’s everyday habits. Does the Minister think this can be achieved in the area of water efficiency, whether by metering or other means? I have to say that in other areas we have been notably unsuccessful in producing such behaviour change.

Thirdly, we will need some radical advances in technology. The report mentions rainwater harvesting as one area, but there are many others too. Do the Government see the European Innovation Partnership on water as likely to be of any value? What in substance does the Minister see it potentially delivering? Finally, picking out the point touched on by the noble Earl, virtual water is an important notion in this, especially for the future. It is an issue which is important internally in the EU because a lot of water is used invisibly, as it were, in manufacturing and service industries. As the noble Earl mentioned, it is also important in the UK and EU more generally in terms of the embodied water in imports. In this sense, it is similar to CO2 levels, where the EU has, on the face of things, been reducing emissions since 1990. However if you include CO2 emissions produced by transferring manufacture to China and other developing countries the picture looks very different. Does the Minister think that virtual water can effectively be measured and can we base practical policy on it? It is an intrinsically important aspect of the total mix when we try to produce a rational policy on water management. In conclusion, though, the Government’s response was pleasingly detailed, interesting and certainly took the work we did with due seriousness.
