Speaking to the Farming Independent this week ahead of the Ploughing Championships, Taoiseach Simon Harris said a lack of certainty around succession in farming is the “number one issue” for the sector.
He said his message to farmers and people in rural Ireland is that farming needs to be “talked up” and not demonised.
“But the number one issue that has genuinely come up with me is, ‘I want my son or my daughter to go into farming, to take on the family farm and I’m not sure what that world looks like’.
“And so the first thing I want to say, and I think this is not unimportant to farmers, I want them to know that I will always champion farming and champion agri-food, and never talk it down.
“The second thing I want them to know is I want to take practical measures to make it easier in terms of succession, passing on the family farm, and also showing people pathways into farming.”
His focus, he said, is “to support young farmers and support the family farm in knowing that it can be passed on to the next generation.”
