Beef Cattle and Sheep (Carbon Footprint)

Eilidh Whiteford Excerpts

Wednesday 26th June 2013 Westminster Hall

[Dr Eilidh Whiteford (Banff and Buchan) (SNP)]

I congratulate the hon. Member for Tiverton and Honiton (Neil Parish) not only on securing the debate but on all his work to drive forward the all-party group’s report.

The impact of livestock production on greenhouse gas emissions and climate change is complex and highly contested. The report does an admirable job of highlighting some of the difficulties associated with carbon footprint modelling, particularly on measuring the impact of carbon sequestration, but that is only one aspect of a much bigger picture.

We need greater recognition of the urgent need to address climate change, and we cannot escape the reality that cattle and sheep produce a lot of methane, but it has become increasingly evident that that is not a zero-sum game; there is an increasing body of evidence showing the significant environmental benefits associated with livestock farming. When we look at both sides of the carbon balance sheet, we see that, overall, methane emissions from ruminants are only one part of the footprint of agricultural production and that cattle and sheep farming, which have been central to our culture for millennia, play a positive role not only in enabling sustainable land use but in maintaining our carbon sinks, protecting biodiversity and creating livelihoods in rural communities.

Those issues are extremely pressing in Scotland, because livestock farming accounts for a high proportion of land use—significantly higher than in other countries of the UK. More than 82% of our agricultural land is grassland, some 70% of which is rough grazing. Those are huge carbon sinks—the Scottish Agricultural College estimates that they represent 80% of the UK’s carbon stocks—so the extent to which carbon sequestration takes place on grassland is very important. We do not yet have enough consistent evidence to reach definitive conclusions, but we know that changing the use of that land could have very adverse consequences, not just for greenhouse gas emissions but for biodiversity and the livelihoods of our farmers and rural communities.

In the past, I have heard simplistic arguments for switching from livestock to arable production, which is a total non-starter in most of Scotland. Some 85% of Scottish land is less-favoured area, and much of it, especially on higher ground, is not suitable for crops. Our climate, combined with marginal land quality, makes arable farming an unviable proposition in many parts of the country. As much of that land is a carbon sink, bringing grasslands and rough grazing into cultivation would, frankly, be destructive and irresponsible in climate and environmental terms; it would increase, not decrease, greenhouse gas emissions.

By contrast, a great deal can be done to maximise the sustainability of livestock farming without compromising livelihoods. Research by Scotland’s Rural College as part of the “Farming for a Better Climate” initiative shows there are lots of simple, practical steps that farmers can take to minimise and mitigate the impact of livestock-related greenhouse gas emissions, from how they manage grazing land to how they use fertilisers and manage waste and slurry; there is also the kind of energy, bedding materials and feed that they use, and even the breeds of sheep and cattle that they rear. Let us not forget that that account cannot end at the front gate—the hon. Member for Sherwood (Mr Spencer), who is no longer in his place, made a point about transport costs—it is also about other aspects of the supply chain, such as packaging and processing costs, all of which potentially have an environmental impact that can be reduced to bring better produce to consumers.

I represent a constituency famous for producing some of the finest beef anywhere in the world. Indeed, Buchan was known as the stockyard of Britain in the days when we still had trains. We are proud of the beef and lamb that we produce in the north-east, but livestock numbers have fallen across Scotland in recent years. As several colleagues from Northern Ireland have said, this has not been an easy time for livestock farmers, who face a range of challenges that are outwith the scope of today’s debate.

When people stop farming, the land stops being stewarded and communities start to diminish. Before we make rash policy decisions, it is important that we have a much better understanding of the role of carbon sequestration. We do not have enough of an evidence base yet, but policy should be based on knowing what we are dealing with and how we can best use our land sustainably. We should recognise that livestock farming is one of the most sustainable ways to manage, maintain and steward grassland and land that is not suitable for cultivation.

I hope the Minister will take on board the all-party group’s concerns about the methodologies used by DEFRA to measure the climate impact of beef and lamb production. I also hope he will recognise the contribution that cattle and sheep farming make to sustainable land management, food security, biodiversity and the well-being of our rural communities.
