From the wiki, perhaps it wasn't as much of a general food shortage as popularly claimed.

The usage of the word famine is a misnomer. Although the potato crop failed, the country was still producing and exporting more than enough grain crops to feed the population. Records show during the period Ireland was exporting approximately thirty to fifty shiploads per day of food produce. As a consequence of these exports and a number other factors such as land acquisition, absentee landlords and the effect of the 1690 penal laws, the Great Famine today is viewed by a number of historical academics as a form of either direct or indirect genocide.
