The biggest sustainability concern for Irish agriculture is "the risk of not having farmers to supply my business in 10 to 15 years," Nick Whelan, chief executive of leading Northern Ireland dairy processor Dale Farm, told the Alltech One Ideas Forum in Dunboyne, Co Meath, this Tuesday.

Farmer and ready meals manufacturer Michael Hoey of Country Crest agreed, adding that a major threat to Irish farming was the double standards between food sold on supermarket shelves and that available from the hospitality industry.
