Global riverine N and P transport to ocean increased during the 20th century despite increased retention along the aquatic continuum

Global riverine nitrogen (N) and phosphorus (P) input, retention and export during the 20th century A.H.W. Beusen A.F. Bouwman L.P.H. Van Beek J.M. Mogollón J.B.M. Middelburg

Short summary
Intensifying anthropogenic activity over the 20th century including agriculture, water consumption, urbanization, and aquaculture has almost doubled the global nitrogen (N) and phosphorus (P) delivery to streams and steadily increased the N : P ratio in freshwater bodies. Concurrently, the cumulative number of reservoirs has driven a rise in freshwater nutrient retention and removal. Still, river nutrient transport to the ocean has also nearly doubled, potentially stressing coastal environments.
