I thank my noble friend Lord Blencathra for his amendments. It is a pleasure to follow the thoughtful speech on them by the noble Baroness, Lady Hayman. Like my noble friend, we want people to understand and engage in nature, but it is also important to increase recognition of and engagement with the term “biodiversity”. It is an internationally recognised term that is gaining popularity with the public, parliamentarians and beyond, not least as a consequence of the extraordinary work of Sir David Attenborough, as the noble Lord, Lord Krebs, pointed out. It confers a direction of travel toward greater diversity, which we want everyone to fully support and engage with.
As the noble and learned Lord, Lord Hope of Craighead, pointed out, and this point was echoed extremely interestingly and thoughtfully by the noble Baronesses, Lady Bennett and Lady Ritchie, “nature” is a more expansive term than biodiversity, often taken to include non-living elements, and is potentially more open to interpretation. It is perfectly possible to enhance nature with limited or no value for biodiversity. Many monocultures—for example, a green grass valley; I am using a different example from the one that I used last time—are considered beautiful examples of a natural landscape, and “nature” can have a high amenity value. If we are to boost biodiversity, sometimes it will
mean moving away from simplistic ideas of what nature should be, and thinking scientifically about how to improve the diversity of living things.
In response to my noble friend Lady McIntosh, I confirm on my noble friend Lord Blencathra’s behalf—if I may—that he is not proposing to renegotiate or replace the international conventions, as I understand it from his introductory speech. However, I want to provide a more detailed interpretation of what we mean by “biodiversity” and why it is important. I do this in response to a number of noble Lords, including my noble friends Lady McIntosh of Pickering, Lord Caithness and Lord Trenchard, the noble Lord, Lord Krebs, and the noble Baronesses, Lady Ritchie and Lady Hayman. The Convention on Biological Diversity, which is being hosted in China at the end of this year and is a massively important moment for biodiversity, defines biodiversity as
“the variability amongst living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems.”
It is important that variability and diversity should be conserved and the benefits for people secured. The UK is playing a leading role in negotiating an ambitious global framework for biodiversity under that convention, and setting targets and policies for biodiversity helps to demonstrate and further that alignment.
From a more technical perspective, the Bill applies the terms “nature” and “biodiversity” for specific purposes. Associated guidance and regulations will make that clear. We certainly want these measures to benefit all aspects of nature for wildlife and other environmental objectives. Substituting “nature” for “biodiversity” in the Bill would risk creating confusion about the purposes of the measures, especially where “biodiversity” is already a well-established term. Measures such as the biodiversity duty or biodiversity net gain are already established and understood policies, being strengthened through the Bill, and our aim should be to improve their functioning, not create confusion with new terminology.
I hope this does not sound facetious but there is an implied assumption within the amendment that people en masse are going to devour the Bill and base their understanding on the Act that we hope it will become. It feels to me that what really matters is delivering the measures in the Bill and the wider communications that will support it. I say to my noble friend Lord Caithness that I am not convinced it is the Act itself that will take people with us; rather, it will be the delivery of good policy, good solutions and the wider comms that we all—not just the Government—are going to have to engage in to advance this agenda.
I reassure my local friend Lord Blencathra that I share and understand his vision and the motivation behind his amendment, as I think does every noble Lord, but nevertheless I ask him to withdraw it.
