22:14 The Minister of State, Department for Environment, Food and Rural Affairs (Mr James Paice)

Taking a longer perspective, last week the Secretary of State published a Command Paper setting out the strong economic, social and environmental case for ensuring that our infrastructure is resilient enough to cope with the effects of climate change. Who can tell whether today’s circumstances are the result of climate change? None of us can. None the less, the document pays particular regard to water infrastructure, which will need to cope, we believe, with hotter and drier summers, more extreme weather events and changing precipitation patterns in the years to come.

As my hon. Friend has said, water may well be today’s oil—or tomorrow’s oil at any rate—so to help realise the Government’s vision of a well-adapted infrastructure network that can continue to support our economy, our infrastructure operators have been instructed to prepare climate risk assessments under the Climate Change Act 2008. My noble Friend Lord Henley will publish those assessments from water companies this Friday.

It is clear from what my hon. Friend and I have said that rights of water abstraction are a major issue for farmers. Work is going ahead, in consultation with farmers and a wide range of stakeholders, on the water White Paper, which we have already announced and hope to publish this autumn. We are considering whether to reform the water abstraction regime to facilitate investment, not least in reservoirs, and to respond to increased variability and the reduced availability of water owing to climate change. Of key interest to farmers will be the potential in such reform to increase the regulatory certainty in the abstraction regime in order to help farmers invest in storage.

We are also funding research into a wide range of issues, including investigating ways to improve water use. My hon. Friend referred several times to the use of spray irrigation, which is by far the commonest form of irrigation, although most people would accept that it probably wastes the most water. It is worth pointing out that those who use trickle irrigation are not subject to abstraction licences, so the more that we can do to improve water usage for irrigation—with more effective and perhaps novel strategies—the better. We are also investing in research that aims to anticipate the effects of climate change, so that we can be more accurate in helping people find the best ways to adapt. There is obviously also an issue when it comes to developing new and sustainable ways of providing livestock with sources of potable water, including novel methods for harvesting, storing and delivering water from rainfall, as well as from traditional sources such as rivers and streams.
