My Lords, I welcome the Bill and declare my family interest as a livestock farmer and other interests in the register.
This is a massive Bill. We can see that, overall, we have worked on this topic in many guises before, and that is well exemplified by the huge sections devoted to amending previous legislation, right up to the Natural Environment and Rural Communities Act 2006. In addition, there is a virtual forest of Henry VIII powers, which I hope your Lordships will be able to narrow and point more clinically where necessary.
The elements I draw to your Lordships’ attention are, first, the statement of principles; secondly, the 25-year plan to improve the environment; and, thirdly, the current calculation of our agricultural emissions. On the first, I hope we can get a bit more detail on the principles we can expect over and above the generalities listed, and I eagerly await the government amendments that my noble friend the Minister hinted at earlier. In its briefing, the Countryside Alliance outlined a few suggestions, and I think there could be merit in its innovation principle and possibly in its appropriate scale principle. The Bill already incorporates the precautionary principle, which might do with clarification on whether it applies to definable harms or must include unknown harms, as it has done before.
Other than straightforward environmental elements, the Bill’s essential contribution is that it combines the element of sustainability with environmental and species recovery. The main strategy for this is already laid out in the 2018 policy paper A Green Future: Our 25 Year Plan to Improve the Environment. This incorporates and addresses more directly the questions of mitigating and adapting to climate change.
As we struggle to find a commercial solution to the capture and storage of CO2 to meet the targets set for us, adaptation and mitigation on land is still one of the major paths we have found, so there is immense pressure on land managers. Anyone who farms will see this as an attempt to manage nature—and there are few things which are more unpredictable than nature. Good scientific data in this field is available for the
carbon potential of forests and peat bogs, and there is a lot on emissions from livestock. However, as yet there is nothing very comprehensive on grassland.
Traditional and organic agriculture are heavily dependent on the benefits that accrue from having ruminant animals as part of their rotation; that is stated in the 25-year plan. To address biodiversity and carbon storage, a necessary place to start is with soil, which is much degraded in some areas. The Agriculture and Horticulture Development Board has produced figures some of which sit uncomfortably with our popular preconceptions. It estimates that degraded arable soils contain only 23 tonnes of carbon per hectare, whereas in mixed woodland and improved grassland the soil contains around 63 tonnes of carbon per hectare. The surprise comes with permanent grassland, which contains 83 tonnes per hectare. Surprisingly, if that is then planted with trees, it might take a few years to balance out the loss of storage capacity with the amount of new carbon to be accumulated in the crop.
The latest news on grassland I have received is that our friends in Australia and New Zealand, with whom we are likely to be sharing our markets, are now working towards net zero in the production of sheep and cattle. This would be an immense challenge to our production, and the industry here will be looking to see if there are lessons that we can learn and how we could move in that direction. Agriculture is currently burdened with responsibility for 10% of UK emissions. If these lessons are meaningful, this could change markedly, and it could bring the association of grazing livestock with carbon emissions more into line with other foodstuffs.
I look forward to Committee stage of the Bill.
