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.
