Setting the scene:
UK farms are said to produce around 46.5m tCO2e in GHG (Greenhouse Gas) emissions each year; that is, around 10% of the total UK emissions. But additionally, we import around 48% of our food, so the carbon footprint from food production is probably much, much higher (and rising). A WWF-UK / Food Climate Resource Network report in 2010 said the actual UK footprint of farming could be more like 30%.
The relationship between farming and climate change has become somewhat fractious over the years. Farmers say that there is a distinct 'anti-meat' agenda out there, with Guy Smith, Deputy President of the NFU (National Farmers Union) saying, "The vegan lobby are hijacking the climate debate."
The politics can be quite confusing. The Conservative government of the 1990s, for example, told farmers that if they improved their standards, that people would be happy to pay a premium for that additional sustainability and welfare. A ban was put in place on sow stalls that restricted the movement of pregnant pigs - it was, the government said - what the consumer wanted. So farmers invested the money to overcome the law, but they were thwarted; there was no such restriction on imported pork and so that consumer support never happened, as people were happy to go for the cheaper (imported) option!
IPCC report:
The NFU, which represents 55,000 British farmers, says that the International Panel on Climate Change (IPCC) report on 'Change and Land', has been misinterpreted by many - and especially the BBC - they say, basically boiling it down to 'eat less meat and save the planet.' They point that the actual text of the report says;
"Balanced diets, featuring plant based foods, such as those based on coarse grains, legumes, fruit and vegetables, nuts and seeds, and animal sourced food produced in resilient, sustainable and low GHG emission systems, present major opportunities for adaptation and mitigation while generating significant co-benefits in terms of human health."
The industry claim that beef produced in western Europe, for example, is around 2.5 times more efficient in how carbon is managed than the global average.
This gets into another contentious issue. Beef production is the perceived bad boy of agriculture, in climate change terms, as it is a high producer of methane and nitrogen oxides - which are more damaging GHG's than CO2. While carbon dioxide takes a bit of a backseat in this discussion, scientists don't necessarily agree on the outcomes.
Methane was responsible for 56% of farming GHG emissions in 2017, and NO for 31%. This comes from the complexities of soil and microbial processes. The debate surrounds how much weighting they are given in the scientific outcomes. There are those who say that since they are the big GHG emitters, they must be weighted highly; the flip side is that their effects are easier to reverse, as they don't remain in the atmosphere as long, so the weighting should be lowered somewhat.
The NFU and the future:
The NFU vision, set out in September 2019, says that this 46.5m tonnes of emissions could be removed completely in the next 20 years. They say that;
- More efficient production will remove 11.5m tonnes
- Farmland as a store for carbon will remove 9m tonnes
- A boost to renewables and bioenergy will account for a whopping 22m tonnes
The NFU say that if farmers are offered rewards, then this is all achievable.
But there has been no real progress on reducing farming emissions since 2008. A 2013 target to plant 5,000ha of trees a year has also proved difficult; in England in the year up to March 2019, only 1,420ha was planted (according to the Woodland Trust). Guy Smith says, "We are happy with trees on farmland as long as it doesn't significantly curtail production. [Otherwise] you'll just offshore the carbon and they will continue ripping down the Amazon rainforest."
Countryside Online say that in 2017 there were 35,000 agri-environmental schemes happening with farmers in England, all helping to protect the environment and enhance biodiversity.
The dairy industry has produced a Dairy Roadmap for 2020 - 2025, setting environmental targets, such as around fertiliser use and hedgerow protections. They claim that GHG emissions from the UK dairy industry have been reduced by 24% since 1990, and that most farmers now undertake nutrient and manure management programmes to minimise water pollution.
The Royal Society for the encouraging of Arts, Manufacturing and Commerce (RSA) Food, Farming & Countryside Commission has a report out that says farming and food systems must be sustainable by 2030 to help with tackling climate change and meeting government targets.
They say meat must come from 'sustainable livestock', and reflect the NFU claim, that farmers could make these big changes over the next decade if they are given the right backing.
One example would be agro-forestry, where trees are mixed with crop and grazing fields. One farmer engaged in this practice, Ben Raskin, says, "There's a lot of evidence that if an animal is sheltered it's more productive - so its' spending less energy keeping its core warm so it can put more energy into producing milk or putting on weight, which is good, obviously, for production on the farm."
The Wrap:
So, what we see is a need to strike a balance between the need for sustainability and putting in place measures to help reduce carbon emissions and combat climate change; whilst simultaneously dealing with the ever growing demand for cheap (or at least reasonably priced) food.
As with other industries facing the climate change conundrum, it will be a mix of innovation, legislation and willing participation that will lead to UK farming successfully reaching their targets (or otherwise).
