Abstract: In this paper, we explore the effects of a public policy that reduces by 50% the use of mineral nitrogen in European agriculture. We use two techno-economic models to investigate the impacts on agricultural production, prices, and land use changes at the EU and global levels. Results show that halving synthetic fertilizer use leads to a decrease in agricultural production, a substantial increase in nitrogen use efficiency, and lower use of organic fertilizer. More importantly, we show that the results will critically depend on the potential for supply side adjustment, particularly, regarding the expansion of cropland area.
