The growing human population is putting pressure on the Earth’s arable land to produce more food, while this land, and other natural resources are deteriorating in quality and abundance as the human-enhanced greenhouse effect strengthens the negative impacts of climate change. This phenomenon is described by Kanayo F. Nwanze, the President of the UN International Fund for Agricultural Development (IFAD) in the sense that, “It is clear that food security and climate change, humanity’s two greatest challenges in the 21st century, are inextricably linked” (UN, 2011).
About 64% of Ireland’s land area is used for agriculture, so it’s impossible to overstate the significance of the sector in environmental terms.
