Reactive nitrogen on earth by human activity, with projection to 2050

Year: 2007 Author: Philippe Rekacewicz, Emmanuelle Bournay, UNEP/GRID-Arendal
Description:
The range of the natural rate of bacterial nitrogen fixation in natural terrestrial ecosystems (excluding fixation in agroecosystems) is shown for comparison. Human activity now produces approximately as much reactive nitrogen as natural processes do on the continents.
