Nitrogen management offers potential for win-win solutions

The Mitigation of Air Pollution and Greenhouse Gases (MAG) Program contributed to papers that highlight how the global nitrogen cycle could change in the 21st century and the extent to which this is reflected in the current set of global emission scenarios.

Increasing use of nitrogen is providing food to the growing world population; at the same time, nitrogen emissions contributed to threats to biodiversity, air and water quality, and climate change.

MAG contributed to papers that highlight how the global nitrogen cycle could change in the 21st century [1] and the extent to which this is reflected in the current set of global emission scenarios [2].

Beyond stock-taking of the current understanding on business-as-usual projections, MAG explored the potential of specific options for mitigation, their immediate costs and benefits, and how they could contribute to other development objectives [3].
