Excess nitrogen pollutes air, soil and water, increases greenhouse gas emissions, and impacts biodiversity and ecosystem functioning. Environmental policy measures have been taken to reduce the impacts of nitrogen on ecosystems and human health. However, while OECD nitrogen emissions have been reduced, the concentrations of nitrogen forms in air, soil and water still remain much too high overall. We need better mapping and understanding of the link between sources, pathways and impacts of nitrogen, that is impact-pathway analysis. Governments also need to establish national nitrogen budgets to make sure that policies to address local and global nitrogen impacts are reducing the overall quantities of excess nitrogen being released into the environment at the national level. Watch this video to learn more about the policy approaches to managing the risks and uncertainty of disrupting the nitrogen cycle.
