Nitrogen: a cross-cutting environmental challenge

Wednesday February 27th, 2019, 14:00-16:00

Theatersaal, Austrian Academy of Sciences,

Sonnenfelsgasse 19, 1010 Vienna


Nitrogen, in all its diverse forms, is of great importance in all environmental spheres - living organisms, soil, air and water. As proteins, nitrogen is an indispensable part of our diet. On the other hand, we are becoming increasingly aware of its harmful effects in drinking water or as an air pollutant and greenhouse gas.

This workshop aims to address the connections between human nutrition and the environmental impact of anthropogenic nitrogen use, as viewed by experts from agricultural, environmental and systems sciences.
