My Lords, I support the amendments in the names of the noble Lord, Lord Whitty, and the noble Baroness, Lady Jones. In my view, both are vital to our own safety: to the protection of our countryside, our health and our environment. As we know, pesticides are not benign. They are applied to our crops to kill insects and any other creature that might be around at the time. It is natural behaviour—if you deny the natural world its own food source. However, pesticides do not just kill the creatures that are feeding on the crops. They also damage us. Numerous studies document the associations between exposure to pesticides, increased incidence of respiratory problems, cardiovascular and renal diseases, as well as the ageing phenomenon, not to mention many cancers. If you are an ordinary member of the public who happens to live near a field, or a school kid in a playground that borders a field that is being intensively farmed, you are open to being occasionally sprayed by pesticides.
Let me give a tiny example. I used to live with my husband in a house that bordered an intensively farmed field. One day at the end of the year, when it was being sprayed to kill the cover crop, the wind changed. I kid you not: within an hour, the entire herbaceous border on to which the spray had come was lying in a muddy heap. It was completely destroyed. Any thought I had that there was anything healthy about these products vanished at that point.
Some 22,000 chemicals are registered and in use in Europe. In December 2018, high quality checks had been completed on 94 of them; half were declared unsafe. There are many large out-of-court settlements involving Bayer, the company that has taken over Monsanto. This leads many people to believe—cynically, some noble Lords might say, but I do not think so—that it is suppressing evidence of the chemical links between lymphomas and other common cancers. We have to protect the population from these serious and damaging chemicals. Without a doubt, we need strong mandatory levels for the areas in which they are sprayed.
I believe—and this takes me straight on to the amendment of the noble Baroness, Lady Jones—that farmers have very little choice at the moment in the way that they farm. The common agricultural policy, which thankfully we are coming out of, has paid people per acre, and therefore the striving has been to produce as much as possible, probably of monocrops. The result has been, since the “green revolution” after the war, the incredible use of more and more pesticides,
insecticides and fertilisers. These have had the result of weakening our soil to the point that the World Health Organization has said that, across the world, we probably only have 60 harvests left. The soils are now working only if they are given chemical additives. The amendment from the noble Baroness is therefore vital, because there are many other ways to farm. As the noble Lord, Lord Krebs, and I found when we were doing our Select Committee on Food, Poverty, Health and Environment, a more healthy way of farming is also a more healthy way of eating.
Climate impacts are being felt across the world—you have to be blind not to see it—and our food supplies are going to be affected. We cannot keep our heads in the sand about it. Here, we have seen soil erosion, more flooding and coastal land inundation. We have also seen extreme weather—we have had it in the last year. We really cannot afford to wait. The proposed new clause provides that, by 2030, we have to start reducing emissions from agriculture, first, through better care of the soil, lower livestock emissions and reducing fertiliser; and also, crucially, by storing carbon in the land—so we need to plant trees. Soil sequesters carbon much better than anything else if left to its own devices. We must protect it, along with peat bogs.
There is so much that farmers can do if they are given the right incentives and the direction. However, we must have a target to ensure delivery. If we are to meet our Climate Change Act target for 2050, we have to get to 50% by 2030. If we do not, it will be too much for the world to take on. That means that the policies that we need must be laid down in this Parliament and the next—but primarily in this one. This amendment will complement the existing clauses in the Bill for financial support and for climate mitigation and adaptation, and it will confirm the Government’s commitment to strong action, at a time when we will be hosting COP 26 next year.
