AGRICULTURAL NEWS - Beef from Brazil, avocados from Mexico, lamb from New Zealand, wines from South Africa and green beans from Kenya – food shopping lists have a distinctly international flavour.
And with many questioning the sustainability of importing so much food from so far away, we are beginning to ask if switching to a vegetarian diet to cut emissions caused by meat production is as sustainable as one might think.
The influence of the global trade of food on local diets and cultural choices has exploded over recent years. Food supply chains operate globally and deliver rural produce to nearly 4-billion people now living in cities and towns.
It was this principle that established the world’s first agricultural research station some 150 years ago when the founders of Rothamsted saw the potential of the agricultural land surrounding London to supply a growing urban population. In the 21st century, the whole world can be your bread basket.
Many are conscious of what they eat – both from a health and environmental perspective. But what is the impact of this? We’re increasingly encouraged to eat less meat to tackle climate change. And meat consumption, in the European Union at least, has reduced and stabilised at around 42-million tonnes over the last 15 years.

And meat consumption, in the European Union at least, has reduced and stabilised at around 42-million tonnes over the last 15 years.
There are also now new labels for different types of meat eaters: flexitarians (only eat meat sometimes) or the reducetarian (aim to eat less meat) that reflect the ways different groups are trying to cut down.
But what about all those fruit, vegetable and staples crossing the globe – can we really label them as more sustainable than eating meat? The growth of ethical food purchases now make up close to 10% of grocery purchases in the UK, which is double that of tobacco. But in addition to the impact of air miles, global land and resource use determine the sustainability of the food we eat – food production can destroy or displace natural resources in order to supply growing demand.

Changing land use to expand avocado production in Mexico, for example, is displacing the rainforest. Or the devastating impact of non-certificated palm oil, used in food but also a whole host of other products. And then there is the issue of food wastage.
Measuring the sustainability of food
However, the first thing we need to be able to do is measure the environmental impact of the food we eat. We can do this for different food supply chains using carbon footprinting methods. The difficulty is that consumers choose foods based on what they like – and this frequently changes but rarely considers the impact of climate change.
