From roast and mashed to chips and crisps, potatoes are eaten in many different forms. They can also be used in a variety of other ways including in beauty products and for household cleaning tasks.

However, a new report by researchers at Scotland’s Rural College (SRUC) has highlighted a 71% reduction in the demand for fresh potatoes in the UK since the 1970s, with consumers switching to alternatives such as rice and pasta.

More recently, the loss of access to export markets for seed potatoes following Brexit represents another loss of demand, particularly for Scotland where seed production is more important due to its disease-free growing conditions and associated ‘high health’ status.

Overall, the report found the potato market was more stable in Scotland than at a UK level, representing nearly a quarter of the overall potato production from farms.

The farm gate production of potatoes in Scotland – including seed and ware potatoes – had a value of around £245m between 2018-2020. This represented 6% of Scottish agricultural output and 22% of UK potato production.

While the UK is now importing more potato products - including processed products - than it is exporting, it is still a net exporter of seed potatoes, of which Scotland accounts for 75% of the area grown in Britain.

Importantly, the contribution of potato production is greater than its farm gate value, with chilled, frozen, dried and cooked processed products representing further economic activity, in addition to the supply chain which has evolved around the industry – including specialised machinery, storage and processing facilities.

Overall, the Scottish potato sector had an on-farm and upstream economic contribution of £507m output and accounted for 2880 full-time jobs.

Report author, senior agricultural economist at SRUC, Steven Thomson, said: “The work on assessing the economic contribution of the Scottish seed and ware potato sectors is a timely reminder of how complex agri-food supply chains are, and that the integrated potato supply chain operates across the UK and beyond.

Scotland has an international reputation for growing high-health seed potatoes, yet the economic contribution of the seed sector was often only reported as the farmgate value.

“This report demonstrates the economic importance of the Scottish seed potato sector to those growing potatoes for processing and consumption in Scotland, the rest of the UK and internationally.

"With growing concerns about the impacts of potato cyst nematodes (PCN), and other diseases, this provides evidence of the importance of the sector that can help justify Scottish Government support for research and development, knowledge exchange and wider policy measures for the sector.”

Chief plant health officer for Scotland Gerry Saddler welcomed the report and said: “This report highlights the significance of the potato sector to Scotland’s rural economy. In particular, it throws a spotlight on how important our seed potato production is for the potato supply chain in the UK but also for many other countries around the world.

“Potato production worldwide is under constant threat from the actions of pests and our changing climate. This report gives a clear indication of what could potentially be lost if the potato sector, working in partnership with the Government, fails to maintain the high production standards built over many years in Scotland.”

SRUC is running a potato roguing course at Mains of Tertowie Farm, Kinellar, from June 17-21.
