Welcome to the European Centre of the INI (INI-Europe)

INI-Europe has been established as a hub of INI-related activities in Europe. More detailed information is available on the concepts and visions of INI-Europe and on the internal structure.

In order to support stringent policy (the Swiss Federal Council defined the goal to reduce ammonia emissions in 2030 by about 40% and nitrogen oxide emissions by about 50% compared to 2005), Switzerland provides information on nitrogen, its use an

An update on the latest activities in Nitrogen has been sent in December 2015. Please sign up for future Nitrogen alerts by signing up to the INI-Europe mailing list (see above).

Eurostat is currently setting up a strategy for agricultural statistics in the next decade and beyond.

„INI Nitrogen alerts“ have been sent – if you wish to be included in future alerts, please sign up to the INI Europe address list as shown above. The complete text of the “Nitrogen alert 2/2015” is accessible here:

Nitrogen plays an important role also in current environmental policy. Details have been compiled in the Nitrogen Alert 1/2015 available here.

This publication from PlantLife summarises current evidence and provides background information to raise awareness of atmospheric nitrogen deposition in the UK, where it is coming from, where it is affecting semi-natural habitats, the impacts on habitats, plants and fungi, and how it is recorded.

Over the past 50 years, human activity has caused significant changes to the world’s ecosystems. Dependency on manufactured nitrogen-based fertiliser to increase crop yields significantly and produce feed for livestock contributes to changes in the global nitrogen cycle. Levels of reactive nitrogen have tripled in Europe and doubled globally in the last century. This is causing unprecedented changes to nutrient cycles and is driving widespread eutrophication of ecosystems and biodiversity loss, exacerbating climate change and causing significant human health impacts.

The report provides further information sources that set out what can be done by different stakeholders to address this issue.

This article not only provides a book review on “The story of N” published by the environmental historian Hugh Gorman. Moreover, it evaluates strategies to tackle problems caused by reactive nitrogen compounds in the environment as described in the book and compares these with current European activities. Both successful abatement examples and the difficulties to achieve progress in other areas are demonstrated.

In this article, W. Winiwarter and coworkers provide an overview of different activities in Europe on management, abatement and science related to environmental effects of reactive nitrogen. While focusing on trans-national activities that exploit the opportunities of European integration, also national approaches that may be influential for all of Europe are being discussed.

The study evaluates the environmental performance of selected dairy farms in the Netherlands. Closing internal nutrient cycles (INC) significantly reduces dairy farm energy use, INC farming reduces the global warming, acidification, and eutrophication potential; nitrogen losses to air and water decrease on average by 5 to 10%.

In a case study in the Netherlands two scenarios of changes in climate, technology, policy, and markets for 2050 are investigated: a ‘global economy’ and a ‘regional communities’ scenario; the first leads to a strong increase in agricultural production, the second to a modest increase in agricultural production and a larger expansion of the nature reserves, with the N losses and deposition remaining at the current level. Nature protection needs more ambitious green policies.

Kevin Hicks

United Kingdom
Deputy Centre Director and Senior Research Associate, Stockholm Environment Institute at York, Environment Department, University of York, UK
Kevin has been a research associate at SEI since 1997 and has 25 years’ experience in the field of air pollution. He has a B.Sc. in Plant Science from the University of Liverpool (1989) and a Ph.D. on ‘The Importance to Upland Vegetation of Enhanced Nitrogen Deposition at High Altitude’ from the Department of Plant and Soil Science, University of Aberdeen, Scotland, UK (1996). His current research interests cover air pollution impacts, especially of nitrogen, on terrestrial ecosystems, linkages between air pollution and climate change, and the transfer of scientific information to the policy process.
He has extensive experience of international cooperation on air pollution issues in Europe and in developing countries and has helped organize various workshops, including a global meeting on Nitrogen Deposition, Critical Loads and Biodiversity in Edinburgh, UK, in 2009. He helped coordinate the 2011 UNEP/WMO Integrated Assessment of Black Carbon and Tropospheric Ozone and is active in the follow-up work in developing countries under the Climate and Clean Air Coalition (CCAC), where he is interested in the development of national action planning and the linkages between energy, food production and water and air quality management in the agricultural sector.
He served on the INI Europe Steering Group under Wilfried Winiwarter from 2013 to 2016, before becoming the INI Europe Director in December 2016.
