My Lords, I declare an interest through my involvement with the Rothamsted agricultural research institute. We have covered a wide range of issues in this group and I thank all noble Lords who contributed to the debate last week and again today. The amendments explore in more detail what we will need to deliver environmentally sustainable agriculture. We have had reference to nature-friendly farming, to agroecological systems, to agroforestry, to organically and ecologically sustainable systems, to the improved nutrient content of crops, to integrated pest management and to the importance of soil health. I agree with all those concepts, but also with my noble friend Lady Quin that we need to be clear about the definitions of these phrases when we use them.
All these systems have detailed research behind them, which reinforces the evidence that harnessing nature can improve farm outcomes, as well as enhancing the environment. Many noble Lords will have seen at first hand the positive impact on farmland productivity that can occur when these techniques are embraced. At the same time, we know that nature-based measures to reduce emissions can make a substantial contribution to tackling climate change while preserving or restoring habitats. We agree that natural ecological processes and agroforestry techniques should lie at the heart of the Bill. When adopted on a whole-farm approach, they will reduce the use of agrochemicals, encourage biodiversity, improve soil health, recycle nutrients, energy and waste and generally create more diverse, resilient and productive agroecosystems.
Last year, the RSA Food, Farming and Countryside Commission report set out the case for bringing agroecology systems out of the shadows and into the mainstream of farming practice. It argued that farmers need to be helped to make that transition and recommended a 10-year programme to provide more research, training and capital grants to make this a reality. This would be an excellent use of the financial assistance in the Bill.
I agree with the noble Lord, Lord Lucas, who talked about the need for a long-term programme of soil monitoring. We face a fundamental eradication of soil fertility that will be difficult to reverse. Our APPG on science in agriculture had an excellent evidence session last year on the numerous research projects taking place on this issue, but what we really need is to bring the evidence together in one place. While I am on the subject, will the Minister update us on the work of the Sustainable Soils Alliance, launched by Michael Gove, that was meant to do just that?
The noble Duke, the Duke of Wellington, specifically mentioned the transition to organic farming. I agree that this also has an important role to play. Organic farms have 50% more wildlife than conventionally farmed land and healthier soils, with a 44% higher capacity to store long-term soil carbon. Clearly, if the soil is more fertile, it increases productivity, so organic farming can make a real difference to biodiversity while sustaining food production.
The noble Lord, Lord Teverson, and others talked about agroforestry. We agree that this system of planting has huge benefits over traditional forestry techniques. We know that the pressure is on to plant more trees. The Committee on Climate Change has set a target of between 30,000 and 50,000 hectares of new planting a year, but so far the Government have fallen well short of that target. It is important that trees are planted in a way that is sympathetic to the countryside and to the environment, rather than the monoculture plantations we have seen in the past. Agroforestry supplies the answer to this. Mixed plantings of trees and shrubs grown around crops can reduce erosion, increase biodiversity and create complex habitats, so we very much hope that financial assistance will be available to help farmers to create this mixed planting economy.
Finally, the amendments in the name of noble Baronesses, Lady Bennett and Lady Finlay, highlight the need to reduce the use of herbicides and pesticides. The noble Baroness, Lady Finlay, in particular, highlighted the potentially damaging impacts of pesticides on health, and recommended looking at the evidence and producing an annual report. These views were echoed powerfully by the noble Lord, Lord Wigley, and the very moving examples he gave. The noble Baroness, Lady Finlay, also rightly raised the need to avoid contaminated products being imported into this country. We agree with these objectives and have our own amendments, Amendment 226 on pesticides and Amendment 173 calling for a national food plan that addresses the problem of pesticide residues. I hope that the debates on these amendments will enable us to set out our position in more detail.
This has been a good discussion and I hope the Minister has heard the collective call for a funding priority for nature-based ecological farming. I am sure we will start to narrow down our priorities in this regard as we continue to consider the Bill, but in the meantime I look forward to her response.
