Farmers in Cumbria say they could lose thousands of pounds a year if subsidies paid by the European Union are reduced.
The Single Farm Payment helps to keep many farmers in business, particularly in upland areas.
The changes would mean that payments are reduced by five per cent for those receiving more than 5,000 Euros per year.
Farmers in Cumbria believe they will lose out more than most other parts of Europe if the changes are introduced because British farms tend to be larger than in other parts of Europe.
"A cut in your farm payments when you're already earning less than the minimum wage - the reality is that your average hill farmer is earning significantly less than the minimum wage on their own farms - so a cut of 5% could be hugely debilitating, could put many farmers out of business and certainly will mean that there's no encouragement for the next generation to follow."
