Farmers are being urged to effectively boycott any 'forced sales' of Irish farms by vulture funds.
The Irish Farmers Association (IFA) says more than 2,500 farms - or around 150,000 acres of land - across the country could be at risk.
It has launched a campaign urging farmers, auctioneers, solicitors and other businesses not to facilitate sales that do not have the permission of a farmer 'who is willing to commit to a repayment plan'.
The association is also calling on farmers to push for more laws to regulate vulture funds and protect borrowers.
According to the IFA, its latest moves represent a 'significant escalation' in its campaign against vulture funds.
IFA President Joe Healy says it is about the community standing together on the issue.
He explained: "I'm a farmer, and if I had a neighbour, and he was trying to deal with the banks or the vulture funds... if that land was put up for sale, I wouldn't get involved in the buying of it.
"I think I can say that on behalf of most farmers around the country."
He also claimed that 'faceless funds have no understanding of farming', adding: “Farm families should be given the time to repay their debts over a longer term to keep the farm intact."
