In 1760 the Industrial Revolution began in Great Britain, in 1801 Ireland joined with Great Britain to form the United Kingdom, and in 1845 the great famine began in the United Kingdom, specifically in Ireland. I'm afraid this feels like moving the goalposts; famine is always going to hit agricultural areas the hardest in any trade-capable country, because even though everyone else still needs food, everyone else still has things to trade for food (and if the agricultural laborers still had anything to trade, there wouldn't be a famine to begin with). It's a bit like saying that the Dust Bowl didn't happen in the industrialized nation of the United States because it happened in Oklahoma.
