My Lords, I support Amendment 196 in the names of the noble Baronesses, Lady Jones of Whitchurch, Lady Parminter and Lady Bennett of Manor Castle, and the noble Lord, Lord Teverson. I also support other amendments in this group, which I will mention when I come to them.
I join other noble Lords in welcoming government Amendment 194B and the new Schedule 14A, which will include nationally significant infrastructure projects in biodiversity net gain. In this context, I also support Amendment 194C, which aims to close a potential
loophole by including other major infrastructure projects, such as those concentred under a hybrid Bill procedure, in the net-gain requirement.
Amendment 196, as we have heard, seeks to remove the 30-year time limit for off-site compensatory habitat under biodiversity net gain. Many Peers have spoken eloquently in support of this change, although some have said that “in perpetuity” may be too long. So there may be a debate to be had: if not 30 years, how long should it be? Still, it should certainly be for much longer than 30 years.
The Government’s argument for the 30-year limit appears to be that landowners may be reluctant to maintain habitats and lock up land in perpetuity. However, if the aim is to protect nature for future generations, it is crucial for net-gain projects to have a longevity of greater than one generation. Furthermore, the development projects that net gain seeks to off-set will often certainly last much longer than 30 years, as the noble Baronesses, Lady Bennett and Lady Hayman of Ullock, mentioned. If a habitat created to compensate for damage by a development can simply be ploughed up after 30 years while the damaging development is left standing, we will not be passing on a guarantee of nature in better condition to the next generation. This is not damage avoided but damage deferred—an asymmetry that punishes nature.
As it stands, the Bill creates a carousel of land-use changes where landowners are paid to off-set environmental harm for a while before turning the land over to some other use. Instead we need lasting habitat that will genuinely help to create a nature recovery network, even if the result is fewer parcels of habitat for sale; that is the price of restoring nature. As the noble Earl, Lord Devon, rightly pointed out, we have to make hard choices about land use.
Furthermore, as others have pointed out, the creation of new habitats and the arrival of new species can often be a long, slow process. We have already heard several examples, to which I add my local RSPB reserve on Otmoor, near Oxford. It was established in 1997 by converting farmland into wetland, and it is still attracting additional new species of birds each year. A limit on the time horizon of net-gain projects will add to concerns already raised by ecologists at the Durrell Institute of Conservation and Ecology at the University of Kent, who found in a recent report that net gain is leading to large losses of green open space, off-set by the promise of better-quality habitats at an uncertain time in the future. They also found that 95% of the off-setting projects produced small disjointed areas of habitat rather than following the principles of
“more, bigger, better, more joined-up”
proposed by Sir John Lawton.
Given the shortcomings already identified in the operation of net gain, surely the opportunity in this Bill is to strengthen the protection of nature where we can, including by lifting the 30-year restriction. In other jurisdictions, such as the United States and Australia, off-sets are required to last either as long as the development itself or for perpetuity. If the Government are serious about creating real gains for nature from development then those gains need to be lasting.
Amendment 198A in the name of the noble Baroness, Lady Young of Old Scone, seems a no-brainer. Just as we have a waste hierarchy, we should surely have a biodiversity hierarchy: do not do harm, minimise harm and, lastly, compensate for harm.
In conclusion, the onus is on the Minister to explain to us why the perfectly sensible Amendments 194C, 196 and 198A should not be accepted. I very much look forward to his response.
