Environment Bill — House of Lords, 2021-06-23
Topic: Environment
John Krebs (Crossbench, Unknown): My Lords, I have added my name to Amendment 24, along with the noble Lord, Lord Randall of Uxbridge, and the noble Baronesses, Lady Parminter and Lady Jones of Whitchurch. I also support Amendments 25, 26, 27 and 202 I was going to speak in some detail to Amendment 24 but the noble Lord, Lord Randall of Uxbridge, did such a brilliant job of introducing it that I do not need to repeat anything he said—he said it far better than I could. What I want to say is this: just over 20 years ago I wrote an article entitled "The second Silent Spring?" Those who follow the environmental literature will know that in the 1960s Rachel Carson wrote a book called Silent Spring, which was really the beginning of the environmental movement. She showed how pesticides, particularly DDT, were causing irreparable damage to wildlife. My article analysed how intensive farming practices have silenced the birds in our landscapes. We now understand that reasonably well; as I mentioned in an earlier debate, we have some good evidence on which to change farming practice. Without Amendment 24—indeed, without going further than Amendment 24, as suggested in the other amendments in this group—I will be able to write an article in 10 years’ time, in the early 2030s, called "The third Silent Spring", which will talk about how government inaction has left us without nature recovery Why is it urgent to act now? I will mention a few reasons; they have already been described in earlier debates. The Minister himself pointed out this afternoon that you cannot conjure up habitats overnight. If you need a habitat such as ancient woodland, lowland heath or marshland, you need years to restore those habitats. As the noble Baroness, Lady Young of Old Scone, said, the species we are concerned about preserving and increasing depend on the habitats they live in Secondly, if the cause of decline has been pollution, it will take years for pollution to disappear from the environment and for us to find alternative insecticides or herbicides that are less damaging to wildlife Thirdly, as we heard from the noble Earl, Lord Caithness, and the noble Lord, Lord Curry of Kirkharle, among others, some species are already affected by the impacts of climate change. In the latest climate change risk assessment, published last week, risks to biodiversity and habitat from climate change are listed as one of the eight priority risks for action in the next two years. It estimates that more than a third of species are at risk of adverse effects of climate change. Unless we take action now to improve the condition of those species, they will disappear My final point in explaining why action is urgent now is that some species will be adversely affected by chance extreme events. For instance, the population of Dartford warblers in Surrey declined by 88% in 2009 because of a cold snap in the February, in spite of the creation of special protected areas of lowland heath. That emphasises that if we are to build resilience to future chance events, we have to act now and not dither and delay. A legally binding target will oblige the Government to come clean about what they mean by Amendment 22 and how they will deliver it, and will prevent further dither and delay while some species decline and disappear I have two more points. The noble Baronesses, Lady Bennett of Manor Castle and Lady McIntosh, and the noble Earl, Lord Devon, among others, asked what the amendment actually means by a "species abundance target". I am sure all noble Lords would agree that not all species are created equal. For instance, would it be counted as a success if the Government’s policies achieved a target of increasing the abundance of clothes moths, hair lice or food poisoning bacteria such as salmonella? Some people may think those are important species to increase the abundance of, but when people think of halting species’ decline or restoring nature they are surely thinking of a wider range of species—and probably none of those three species Amendments 26 and 27 try to provide a more precise characterisation. We have heard a number of suggestions. The noble Baroness, Lady Bennett of Manor Castle, suggested, for example, that species at risk of decline or extinction be a possible starting point. The noble Lord, Lord Randall of Uxbridge, suggested the species in the NGO State of Nature report. Another obvious alternative would be to include the 943 species and 56 habitats covered under Section 41 of the Natural Environment and Rural Communities Act 2006 I hope the Minister can shed a bit of light in his response on what sort of group of species will be included in the target. I also hope the target will be strengthened, as the amendment suggests. Can he also suggest how the expert group he referred to will combine these different species into a single metric? This will involve some weighting of their relative importance, as the noble Lord, Lord Cameron of Dillington, mentioned a few minutes ago I have one final point. The Government should be explicit about how potential trade-offs, which my noble friend Lord Vaux of Harrowden referred to earlier, might be managed. Restoring a habitat for one priority species may result in loss of habitat for another. Species A may need more marsh habitat, while species B may need dry meadows. The supply of land in this country is very limited, so choices may well have to be made. I hope the Minister will tell us a bit about how this might be done In summary, while government Amendment 22 looks at first sight to be a fantastic commitment, the more you look at it, the more questions it raises. I very much hope, as other noble Lords have said, that the Government will take it away and revise it, to meet the concerns that have been raised about its current form.
