The true cost of food has been an issue that has affected me since the beginning of my farming life. Ever since I started farming back in the 1970s, I produced milk, wheat and carrots as sustainably as I could manage, but found it difficult to compete with my neighbours who were using chemical production methods, heavily subsidised through the Common Agricultural Policy.

It did occur to me that the root of the problem was connected to the failure of the market to take into account the cost of the damage done by such chemical methods to the environment and public health, evidence of which I recently uncovered when I found a copy of an old article in the Guardian newspaper written in 1984 in my garage. It featured the Sustainable Food Trust board member, Peter Segger, and I asserting that intensively produced crops reliant on pesticides and fertilisers did not actually produce cheap food at all, despite what the price on the shelf may say.

Impacts from food production

Food production has multiple impacts both on and off the farm. These can often be negative, such as the pollution of rivers, the emission of greenhouse gases, the spread of antibiotic resistance, the degradation of soil, the rise of obesity and the spread of disease. Yet none of this damage has featured in the balance sheet of farmers using chemical methods. Although these costs are not reflected in the price of food, consumers are paying in other hidden ways, such as through taxes, health care costs, pollution clean up and water rates. There are also deferred costs, including emissions causing climate change which will have to be paid for by subsequent generations.

Distorted markets

Back in the 1980s, before a full understanding of the scale of the impact of uncosted damage to the environment and public health became clear, I naively assumed we could solve the problem in the marketplace. Throughout my years at the Soil Association we attempted to tackle this through the development of standards which allowed us to charge premiums for organic food. The intention was to ensure farmers received a fair income for the efforts they made in adopting more sustainable production methods. However, even though the organic market has grown, organic producers still have to compete unfairly with a system that financially benefits the intensive, large scale chemical farmers who are receiving misdirected agricultural subsidies and are not charged for the damage they cause to the environment and public health.

More recently, I have come to realise that our economic system is distorted and totally fails to represent the reality of the costs and benefits associated with different methods of food production. But it wasn’t until I set up the Sustainable Food Trust in 2011 that we began to develop the concept of True Cost Accounting.

Towards true cost

This evolving way of thinking seeks to assess the costs and benefits of different food production systems. In doing so, those using production methods that are detrimental to the environment and society would have to pay for the damage they do, while those that are sustainable and deliver a wide range of benefits would be rewarded. This should ultimately have the effect of making food produced in a damaging way expensive, or ideally phased out, whilst sustainable food could become more affordable.

Armed with the necessary knowledge and data, governments would be able to introduce policy and economic measures that bring about the change needed. This could involve a mixture of ‘carrots and sticks’ such as taxes on damaging inputs and subsidies for sustainable practices.

In 2013 we held our first events on this theme. First a symposium in Louisville, Kentucky, followed by a two day event in London. This conference included speakers such as Pavan Sukhdev, leader of ‘The Economics of Ecosystems and Biodiversity’ (TEEB), a global initiative focused on the economic benefits of biodiversity, and Professor Jules Pretty, author of key papers that put costs on externalities.

In April 2016 we held another major event spanning three days in San Francisco. The True Cost of American Food conference brought together high level leaders, scientists and influential thinkers in the world of food and farming. Topics covered ranged from a detailed critique of production systems such as CAFOs (concentrated animal feeding operations), to hard hitting issues such as public health, to bigger picture questions such as how can we put a price on the ‘priceless’.

Can we measure everything?

As part of this conference we worked with Dr Harpinder Sandhu, of Flinders University South Australia, to develop a sustainability assessment tool that could be applied to individual farms. During the course of his research, Sandhu assessed three US farming operations, including organic dairy farms supplying the Straus Organic Creamery in Petaluma, Joel Salatin’s diversified Polyface farm in Virginia and Jim Erdahl’s corn and soy farm in Minnesota. In each case, Dr Sandhu created his own accounting system of the farm which included all inputs and outputs, not only product sales, but also environmental and social impacts.

Sandhu uses ecological economics to quantify and give a monetary value to environmental and social benefits and costs such as pollution, pollination, soil carbon sequestration and knowledge generation. For example, with his accounting system, Sandhu illustrates the value of knowledge generation on Polyface farm which runs regular farm tours and workshops. Or, for the organic dairy farms, he illustrates the environmental costs associated with animal feed and manure management and for the corn and soy farm there are environmental costs associated with GHG emissions from fertiliser use. In summary, this accounting system illustrates that diversified farms generate more environmental and social benefits than monocultures. Sandhu: “When these benefits are included, farm products [from diversified farms] present better value to society as a whole than the so called cheap beef and milk from feedlot systems, which isn’t really cheap at all.”

Academics like Sandhu approach the complex task of quantifying and putting a price on the costs of producing food in many different ways. In the longer term it would be helpful if they could work towards a common methodology so that comparisons could be drawn more easily. One question is whether it is possible, or even ethical, to value everything. We can only attach surrogate (not actual) costs to animal suffering, species extinction or a breathtaking view, for example. Yet, agricultural policies dictate the food systems we have, and these are set by politicians and largely based on harsh economics. So while we need to recognise the limitations and the potential traps of placing a monetary value on everything, doing so is necessary for the widespread transition to more sustainable food production, processing and consumption.

Challenges

Of course our advocacy of True Cost Accounting has its challenges. Being an issue of immense complexity, spanning the worlds of economics, public health, ecosystems, environment and society, it requires an integrated approach. Unfortunately, at least until recently, these different worlds have tended to operate in siloes. For true cost accounting to work, we must share knowledge and data, and adopt a more systemic way of thinking.

Another major issue is conducting the research and gathering the information. At the moment we have relatively little data on the costs of agricultural externalities, and while we are currently drafting a report that will bring together the known research, there remains a huge amount of work to do. Governments urgently need to fund and support research in this area, specifically looking at the impact of agriculture on things such as public health and the environment, but crucially, attempting to put monetary values on these impacts.

A political opening

This data is sorely needed as we rework agricultural policy post-Brexit. With potentially quite dramatic subsidy changes looming on the horizon, we must take this as an opportunity to put sustainability at the heart of future policy. There are encouraging signs that a consensus of opinion is emerging and that such an approach will be the best way to improve the economic environment for sustainable food production. As an example, Dame Helen Ghosh, chief executive of the National Trust, made national headlines when she called for a major shift in post-Brexit farm support with all future subsidies needing to be directly connected with tangible, measurable and ultimately monetised public benefits. Even a few years ago, when Dame Helen was permanent secretary at Defra (Department of Environment, Food and Rural Affairs), calling for such a change in the framework of farm support would have been inconceivable.

So, although more than 30 years have passed since Peter Segger and I were calling for such changes in the Guardian article of 1984, at last the external conditions have arisen whereby such actions could become politically possible.
