The Farming Community Network (FCN) warned of the consequences if not enough attention was given to the human cost of political and legislative decisions.
FCN chief executive Charles Smith said: “In the run up to leaving the European Union there are bound to be winners and losers,” adding consideration had to be given to the impact on farming families of any change to subsidies.
The charity, which has been supporting farmers for more than 21 years and helps about 6,000 people each year, said changes to the annual basic farm payment and the establishment and development of markets for farm produce were of great concern to farmers.
“FCN has an important role to play by raising concerns about the effect of changes on the daily lives of the farming community,” added Mr Smith.
“We will be urging those who are framing the future to consider, very carefully, the potential human cost of their decisions.”
