Abstract

At a spatial resolution level of 5 by 5 arc minute, we estimate anthropogenic nitrogen (N) loads to freshwater, globally. The global anthropogenic N load to freshwater systems from diffuse and point sources in the period 2002–2010 was 32.6 million tonnes per year. China contributed about 45% to this global anthropogenic N load. The USA was the second largest contributor (7%), followed by Russia (6%) and India (5%). Three quarters of the N loads came from diffuse sources (agriculture), 23% from domestic point sources and 2% from industrial point sources. Among the crops, production of cereals had the largest contribution to the N loads (18%, of which 7% wheat and 6% maize), followed by vegetables (15%) and oil crops (11%). It is estimated that, globally, 18% of the total N input on crop fields in the form of artificial fertilizer and manure leaches to freshwater systems.
