The authors explore the potential of sustainable extensification of agriculture by reducing N inputs and livestock densities. A 2030 scenario for the EU27 reducing production and consumption of animal products by 50% (demitarean diet) decreases N pollution by 10%. In Europe, extensification of agriculture is sustainable when combined with adjusted diets, a change to organic farming, and the externalization of environmental costs to food prices.
