The atmosphere-land-water connectivity of nutrients is not altogether accounted for in the Ganges Basin despite recent studies highlighting its importance. Together with surface inputs, rivers receive N and P through atmospheric deposition (AD), directly on water surfaces, and through lateral transport. Globally, anthropogenic- input of reactive nitrogen (Nr) has increased from ˜15 Tg in 1860 to 187 Tg by 2005 (ref. 1) and is predicted to be doubled by 2050 (ref. 2).

Abstract


The atmosphere-land-water connectivity of nutrients is not altogether accounted for in the Ganges Basin despite recent studies highlighting its importance. Together with surface inputs, rivers receive N and P through atmospheric deposition (AD), directly on water surfaces, and through lateral transport. Globally, anthropogenic- input of reactive nitrogen (Nr) has increased from ˜15 Tg in 1860 to 187 Tg by 2005 (ref. 1) and is predicted to be doubled by 2050 (ref. 2).
