This document summarizes a presentation given at the Ireland Phosphorus Sustainability Workshop in Belfast on June 21, 2017. The presentation discusses phosphorus stewardship in Ireland and the EU, including challenges around finite phosphorus resources, its role in food security and critical industries, and its role as a water pollutant. It provides data on phosphorus flows within the EU, including imports/exports, losses, and use efficiencies across different sectors. It also compares phosphorus use between Ireland/UK and the overall EU. The presentation promotes the transition to more sustainable phosphorus use through reducing losses and improving recycling, and highlights the role of nutrient platforms like the European Sustainable Phosphorus Platform in enabling collaboration and innovation toward
