My Lords, the pressure on our wetlands, rivers and aquifers is huge and growing. Demands for water from domestic and business customers, and from agriculture, are increasing. Climate change is reducing the supply and reliability of rainfall, as well as increasing our demand on water resources. I cannot believe that it is 20 years since I started campaigning for the withdrawal of damaging abstraction licences; it is a sad state of affairs that the argument has not yet been completely won.
I cannot support Amendment 176 in the name of the noble Lord, Lord Carrington. Water is a resource that we all must share. Historic abstraction rights are just that—historic happenstance—and can be inequitable in their impact on the environment and other water users. Overabstraction of water from low-flow rivers can have long-lasting damage; it can cause fish and other wildlife to be lost for ever, particularly in chalk streams. None of that will help with the Government’s biodiversity target if overabstraction continues. It can also result in salt water contamination of water resources, including groundwater, which is difficult to remediate.
In the Water Act 2003, we made some progress with the right to compensation for holders of licences that were causing serious damage being withdrawn, but that was a small provision, and rarely used. The Water Act 2014 removed the requirement to pay compensation for water company abstraction licence changes, which was another step forward.
Many farmers already farm under sustainable abstraction licences and have developed innovative solutions for reducing the amount of irrigation water needed, and developed more on-farm reservoirs, as outlined knowledgably by the noble Lord, Lord Cameron of Dillington. We need to pay farmers under ELMS for developing innovative solutions in adapting to a changing climate. Amendments 176A, 180A and 187ZA, tabled by the noble Lord and outlined so eloquently by him, are highly reasonable, practical and fair, and would enable an acceleration of the deadline by which abstraction should cease. His amendments are based on a lifetime of practical agricultural experience and gain much stature from that. There can be no argument at all about removing compensation for variations to licences to remove excess headroom, where historic licences with unused headroom are hampering the more flexible allocation of water.
I also support Amendment 179A—again, one of the splendid amendments of the noble Lord, Lord Carrington of Dillington—which would correct the narrow definition of ecological health and enable changes to be made in licences that are preventing the effective conservation management of sites of special scientific interest and where abstraction is causing damaging low flows in chalk streams and the main salmon rivers.
