The International Nitrogen Initiative (INI) was established in 2003 as a joint project between SCOPE and IGBP to address the nitrogen paradox and find solutions to the problems caused by excess nitrogen. INI has regional centers, including INI-Europe which is directed by Wilfried Winiwarter at IIASA. Key areas of focus for INI-Europe include regional nitrogen budgets, effects of nitrogen on ecosystems and human health, and links between nitrogen and phosphorus use and environmental impacts. INI-Europe has produced several reports including the European Nitrogen Assessment and has contributed to several conferences on nitrogen issues.
2. Embedding
• INI was established in 2003
• Joint SCOPE and IGBP Project
• Tries to find solutions to the nitrogen paradox
(needed for plant growth, but causing damage
in excess)
4. INI - Europe
• Director: Wilfried Winiwarter, IIASA
• Steering Committee:
– Bruna Grizzetti, JRC – EU, Italy
– Hans van Grinsven, PBL – Netherlands
– Kevin Hicks, SEI – UK

5. Key focal areas
1. Regional N budgets and N pathways/emissions
2. N compounds in air and water and their relation to effects on
ecosystems and human health
3. Effects of N inputs on terrestrial ecosystems, in interaction with
air quality and climate change
4. N inputs and effects on aquatic/marine ecosystems
5. Links of N and P use and transfer on food productivity and
adverse environmental impacts
6. Regional boundaries for N and P use in view of food production
and adverse environmental impacts
7. N management across Europe and current best practice in
Europe
