My Lords, I apologise to the Committee for not speaking at the Second Reading of this Bill; I was not on the team at that point.
I am grateful to my noble friend Lady Jones of Whitchurch for tabling the two amendments in this group, which we understand to be probing amendments. As my noble friend said about Amendment 2, she is challenging how far technology is applied. Do we want to go beyond certain sectors? How far beyond agriculture do we want to go? Amendment 31 is about the wider environmental concerns and reporting on the potential disruption to the farming ecosystem, which could have adverse effects on other plants.
As several speakers noted at Second Reading, the use of gene-editing technologies in plants is far less contentious than in animals. There is not only a much larger body of evidence from research institutions, following years of trials, but that evidence points to the risks being substantially lower. However, even if the risks are lower and potentially easier to mitigate, we must remain mindful of them. Regardless of whether these technologies are used for plant or animal life, we are dealing with processes that accelerate natural events and which may have—we have already heard this phrase—unintended consequences. Indeed, I have heard that phrase in your Lordships’ House over and again during the process of many Bills this Session. It seems to point to an uneasiness with what is being proposed and a lack of thinking things through during the process of legislation.
One imagines that the bulk of releases and marketing authorisations under this legislation will relate to agricultural products. If we can produce certain crops in a more efficient manner, or make them less susceptible to increasingly frequent extreme weather events, that could be a good thing. But we must remember that agricultural crops live alongside wild plants—grasses, wildflowers, trees and hedgerows—all of which have their own important roles in the natural world and in the careful and precious ecosystem. These amendments allow us to consider how new gene-edited varieties of crops will live alongside and interact with other types of plant life
It may be that there is a place for these technologies beyond agriculture, such as making certain tree species less susceptible to disease. I remember well, as leader of Newport City Council, when we had to deal with the significant problem of ash dieback. Large areas of ash trees were felled, with a significant impact on local wooded areas. We had a policy of planting two trees for every tree cut down on land we were responsible for, so felled ash trees were replaced with other suitable trees. If technology could help prevent such drastic measures, that can only be a positive thing.
Regardless of the precise applications of the technologies, it is not clear that the Bill as drafted takes full account of the potential consequences of new plant varieties
once they are released. The Government’s environmental land management schemes and other initiatives are trying to halt the steady decline in our biodiversity which has been caused in part by the loss of meadows and hedges and the habitats they sustain. These efforts are hugely important, and there is a role for gene-edited plant varieties as we seek to achieve that goal. However, concerns have been raised by experts in this Committee that seemingly minor changes to agricultural, forestry and other land management practices arising from the use of new plant varieties could inadvertently have significant impacts on soil quality and wildlife in the medium to long term. These amendments provide the Government with an opportunity to address these concerns and outline how they will ensure that this new regime fits into efforts to protect and enhance our natural environment. I urge the adoption of them by the Government.
